Fire suppression device formed inside the switchgear {FIRE SUPPRESSION DEVICE FORMED INSIDE SWITCHGEAR}

The present invention relates to a fire suppression device formed inside a switchgear, and specifically, a plurality of detection sensors each formed at the other end of a plurality of injection ports, a chemical agent coupled to the other side of the first injection passage, and in which a powder chemical agent for fire extinguishing is stored. The invention relates to a fire suppression device in which when a storage unit and a plurality of detection sensors detect a fire, a plurality of injection holes are opened and a fire extinguishing powder chemical is ejected, and the fire extinguishing powder chemical can be formed of expanded glass.

In general, a switchboard refers to a power facility that receives special high-voltage electricity of 22,900 [V] from the Korea Electric Power Corporation and reduces it to the required operating voltage of 380 [V] or 220 [V].

The switchboard is the main power facility that supplies electricity to places where electricity is used, and its role is a very important facility. If an accident occurs at the switchgear, the entire building or factory will lose power, so stable operation is a very important task.

To explain the configuration of the switchboard in detail with reference to Figure 1, in the case of an abbreviated facility, a voltage of 22,900 [V] is supplied from the device that protects power, which is the responsibility demarcation point (property limit point) of the Korea Electric Power Corporation, to the consumer, which is a place where electricity is used. CH (Cable Head) - LBS (Line Breaker Switch) or ASS (Auto Section Switch) - PF (Power Fuse) - Connected to TR (Transformer) 1st through MOF (Metering Out Fit), and from TR 2nd, 380[ It is used as a power source and light electric load at low voltages of 220[V] and 220[V].

Therefore, the inside of the switchgear is separated into separate spaces into a special high-voltage panel and a low-voltage panel, and the common features are overload due to an increase in electricity usage, occurrence of sparks due to the corona phenomenon due to partial discharge in the air, and There are many cases where fire occurs due to heat generation due to poor contact or explosion due to short circuit.

Transformers used to lower voltage are largely divided into dry type and oil-immersed type depending on the type. In particular, in the case of the oil-immersed type, the transformer has an iron core inside and is made up of a special high-voltage coil and a low-voltage coil, and the entire inside is filled with insulating oil for insulation and cooling effects.

Typical conditions that insulating oil must meet include high dielectric strength, high flash point, and high chemical stability.

This insulating oil is a necessary material for the efficient operation of the transformer in normal times, but in the event of an accident for various reasons, it can lead to a fire. When a fire due to an explosion starts in earnest, the oil inside is ejected to the outside, causing a large fire. It often leads to fire, and extinguishing the fire is very difficult.

In particular, electrical fires in the switchgear lead to oil fires, and the enclosure of the switchgear is made of metal, making it very difficult to open the heated door, which makes extinguishing the fire even more difficult.

Therefore, there is a need for a fire suppression device that can minimize large-scale fires as much as possible by extinguishing the fire quickly and within the minimum time when a fire accident occurs in the switchgear for the above reasons.

First, the plurality of injection holes 100 is composed of a first injection hole 110, a second injection hole 120, and a third injection hole 130.

Referring to Figures 2 and 3, a first injection passage 210 is formed to extend in the longitudinal direction inside the switchboard, and a first injection hole 110 is formed on one side of the lower part of the first injection passage 210 in a vertical direction. It is formed by extending to

In addition, the second injection hole 120 is formed at a point below the first injection hole 110 and is spaced apart at a predetermined distance on one side of the first injection hole 110, and the third injection hole 130 is It is formed at a point below the second injection hole 120 and is spaced apart at a predetermined distance on one side of the second injection hole 120.

At this time, the plurality of control units can control the operation of the first detection sensor 410, the second detection sensor 420, and the third detection sensor 430, respectively.

In addition, in FIGS. 1 and 2, for convenience of explanation, the number of injection orifices 100 formed in the first injection passage 210 is shown as three, but the number of injection orifices 100 formed in the first injection passage 210 is It is not limited to this and may be three or more or fewer.

A second injection passage 220 is formed to extend in the vertical direction on the other side of the lower part of the first injection passage 210, and a drug storage portion 300 is formed in the lower part of the second injection passage 220.

A fire extinguishing agent capable of extinguishing a fire is stored inside the chemical storage unit 300, and the fire extinguishing agent is preferably expanded glass in the form of a porous body.

A fire that occurs within a switchgear does not end with the fire itself, but causes further damage to many people due to a long-term power outage, and recovery takes a long time due to the use of water.

On the other hand, expanded glass formed of a porous body has the advantage of being able to extinguish quickly without involving any moisture because the material characteristic is silicon (Si), thereby greatly saving the time required for recovery and restoration following a power outage. .

Expanded glass made of a porous body is made of a porous body, so it is light compared to its volume and is very resistant to heat.

Next, Figures 4 and 5 show the internal configuration of the first injection hole 110 according to the present invention.

Figure 4 shows the first injection hole 110 when power is not supplied to the electromagnet coil 112 according to the present invention, and Figure 5 shows the first injection hole 110 when power is supplied to the electromagnet coil 112 according to the present invention. The first injection port 110 is shown.

Referring to FIG. 4, the first injection hole 110 is composed of a supply passage 111, an electromagnet coil 112, a fixed part 113, a movable part 114, and () (115), and the supply passage 111 is formed to extend vertically inside the first injection hole 110, and the fire extinguishing agent moves through the supply passage 111 and is ejected toward the outside.

It is preferable that the fixing part 113 is formed at a point on the other side of the supply channel 111 with respect to the supply channel 111, and the position of the fixing part 113 is fixed.

A movable part 114 is formed on one side of the fixed part 113, and the movable part 114 is formed at a point of the moving passage 115 to prevent the extinguishing agent moving through the moving passage 115 from spewing out. Do it.

That is, when the movable part 114 is formed at one point of the moving passage 115 and the detection sensor 400 does not detect a fire because a fire does not occur, the fire extinguishing agent is directed to the moving passage 115 from the outside. This means a case where it is not necessary to eject.

On the other side of the fixing part 113, electromagnet coils 112 are formed to be spaced apart at a predetermined interval, and a supply passage 111 may be formed to extend in the vertical direction on the top of the electromagnet coils 112.

As will be described later, the movable part 114 can move through the groove formed inside the fixed part 113 and come into contact with the electromagnet coil 112, so the movable part 114, the fixed part 113, and the electromagnet coil 112 are It is desirable that they can be positioned on the same line in the longitudinal direction.

The supply passage 111 can be connected to a power supply unit 500 formed outside the first injection hole 110, and power can be supplied to the electromagnet coil 112 through the power supply unit 500. The specific process of supplying power to the electromagnet coil 112 through the power supply unit 500 will be described later.

It is preferable to be formed in the same way as.

Referring to FIG. 5, when a fire occurs inside the switchboard and the detection sensor 400 detects the fire, the detection information can be transmitted to the power supply unit 500 through the control unit formed inside the detection sensor 400. there is.

When detection information is transmitted to the power supply unit 500, power is supplied to the electromagnet coil 112, and current flows through the electromagnet coil, forming a magnetic field around the electromagnet coil 112.

The electromagnet coil 112 is preferably formed as a solenoid made by winding a coil around a cylindrical iron core. When an electric current flows through a cylindrical coil, a magnetic field is formed, and when an iron core is inserted into it, a stronger magnetic field is obtained. Solenoids have a simple manufacturing process and are economical, so they are used in various fields such as daily necessities, office supplies, and automobile parts. Since this is a known technology, detailed description will be omitted.

When a current flows through the electromagnet coil 112, the electromagnet coil 112 attracts the movable part 114, causing the movable part 114 formed at one point of the moving passage 115 to move in the longitudinal direction. The other end is in contact with the electromagnet coil (112). That is, the movable part 114 is preferably made of a magnetic material.

At this time, the movable part 114 that was blocking one point of the moving passage 115 moves in the longitudinal direction, so that the moving passage 115 is opened and the fire extinguishing agent can be ejected to the outside through the moving passage 115.

The movable part 114 can move in the longitudinal direction by passing through a groove formed inside the fixed part 113, and a detailed description of this will be provided later.

Next, Figure 6 shows the configuration of the movable part 114 when power is not supplied to the electromagnet coil 112 according to the present invention.

Referring to FIG. 6, a first movable part groove 1141 is formed at one point on one side of the moving passage 115 according to the present invention, and a fixed part groove 1131 is formed inside the fixed part 113.

When power is not supplied to the electromagnet coil 112, one end of the movable part 114 is inserted into the first movable part groove 1141 and the other end of the movable part 114 is inserted into the inside of the fixed part groove 1131. .

At this time, the length of the first movable part groove 1141 and the fixed part groove 1131 in the vertical direction is long enough to enable the movable part 114 to move within the first movable part groove 1141 and the fixed part groove 1131. It is preferably formed to a length of (the difference between the vertical length of the first movable part groove 1141 and the fixed part groove 1131 and the vertical length of the movable part 114 is preferably 10 cm or less).

That is, one end of the movable part 114 is coupled to the first movable part groove 1141 formed on one side of the moving passage 115, and the other end of the movable part 114 is fixed to the fixed portion 113 formed on the other side of the moving passage 115. ), so that when a fire does not occur, the position of the movable part 114 is fixed to a point in the moving passage 115, so the fire extinguishing agent is not ejected to the outside.

Figure 7 shows the configuration of the movable part 114 when power is supplied to the electromagnet coil 112 according to the present invention.

Unlike FIG. 6, the movable part 114 shown in FIG. 7 can be seen moving in the longitudinal direction.

A second movable part groove 1142 is formed on the other side of the fixing part 113, and the vertical length of the second movable part groove 1142 is the same as the vertical length of the above-described first movable part groove 1141. It is desirable.

After a fire occurs, the fire is detected by the detection sensor 400, and when the power supply unit 500 receives fire detection information from the control unit formed inside the detection sensor 400, the power supply unit 500 uses the electromagnet coil 112. will supply power.

When power is supplied to the electromagnet coil 112, the electromagnet coil attracts the movable part 114 inserted into the first movable part groove 1141, and the movable part 114 moves toward the other side so that the other end of the movable part 114 It comes into contact with the electromagnet coil (112).

At this time, the movable part 114 can move through the fixed part groove 1131 formed inside the fixed part 113, and as a result, one end of the movable part 114 is inserted into the fixed part groove 1131 to form the movable part 113. The other end of 114 is formed by being inserted into the second movable groove 1142.

That is, the first movable part groove 1141, the fixed part groove 1131, and the second movable part groove 1142 are formed in communication, so the first movable part groove 1141, the fixed part groove 1131, and the second movable part groove ( 1142) is preferably formed on the same line in the longitudinal direction, and the movable part 114 is divided into a first movable part groove 1141, a fixed part groove 1131, and a second movable part groove depending on whether or not power is supplied to the electromagnet coil 112. It can move through the interior of (1142).

Therefore, as the other end of the movable part 114 comes into contact with the electromagnet coil 112, the movable part 114 that was blocking the moving passage 115 moves to the other side, opening the moving passage 115, and the drug storage unit 300 ) The fire extinguishing agent stored in moves to the first injection port 110, the second injection port 120, and the third injection port 130 through the first injection passage 210 and the second injection passage 220.

Thereafter, the fire extinguishing agent flows to the outside of the first injection hole 110, that is, to the inside of the switchboard, through the movement passage 115 formed inside the first injection hole 110, the second injection hole 120, and the third injection hole 130. It erupts and extinguishes the fire.

Next, the configuration of the power supply unit 500 according to the present invention will be described in detail with reference to FIG. 8.

The power supply unit 500 consists of an AC supply unit 510, an AC/DC converter 520, a DC supply unit 530, a charging unit 540, and an ATS, and converts AC to high voltage/low current using the AC supply unit 510. The voltage is first transmitted, and the AC voltage is converted to DC voltage using the AC/DC converter 520.

Afterwards, the DC voltage converted to DC voltage is supplied to the electromagnet coil and the detection sensor 400 using the DC supply unit 530. In other words, power is supplied to the electromagnet coil 112 and the detection sensor 400. Since this is a known technology, detailed explanation will be omitted.

That is, when a fire is to be extinguished in a state where there are no errors or abnormalities in the internal components of the switchboard, power is supplied to the electromagnet coil 112 through the power supply unit 500.

On the other hand, if an error or abnormality occurs in the internal components of the switchboard and 220 [V], the commercial power, cannot be supplied, the detection sensor 400 and the nozzle 100 for fire suppression may not be able to operate. It can reach.

Therefore, in order to solve this emergency state, by adding a power supply circuit capable of charging within the converter in preparation for an emergency, the power charged in the charging unit 540 formed inside the converter is transferred to the Automatic Transfer Switch (550). ), it is possible to continuously supply DC12[V] power.

The Automatic Transfer Switch (550) is a device that is installed between commercial power and emergency power and connects the commercial power to the load during normal times, but switches to the emergency power in the event of a commercial power failure or power outage. In other words, it is a device that automatically switches from the KEPCO line to the emergency generator so that power is supplied to the emergency generator in the event of an emergency.

If something goes wrong with the commercial power, you can quickly turn off the commercial power and connect to the emergency power using the automatic transfer switch (550), ensuring a smooth power supply and quickly and easily shutting off the commercial power in the event of an emergency. This is effective in preventing major accidents.

Figure 9 shows another embodiment of a fire suppression device formed inside a switchboard according to the present invention.

A 1-1 injection hole 140 is formed to extend vertically on one side of the lower part of the first injection passage 210, and the lower end of the 1-1 injection hole 140 is a 2-1 injection hole 150 to be described later. It is formed by tilting at a predetermined angle toward the part where it is located.

That is, the lower end of the 1-1 injection hole 140 is preferably formed so that the fire extinguishing agent is ejected toward the other side of the 1-1 injection hole 140, and the first detection agent is provided on one side of the 1-1 injection hole 140. A sensor 410 is formed.

A 2-1 injection hole 150 is formed on one side of the 1-1 injection hole 140 and spaced apart at a predetermined interval, and the 2-1 injection hole 150 is a part of the lower part of the first injection passage 210. It is formed by extending in a direction perpendicular to the point.

On the other side of the lower part of the first injection passage 210, the 3-1 injection hole 160 is formed to extend in the vertical direction, and the 2-1 injection hole 150 is located at the lower end of the 3-1 injection hole 160. It is formed by tilting at a predetermined angle toward the part where it is formed.

That is, the lower end of the 3-1 injection hole 160 is preferably formed so that the fire extinguishing agent is ejected toward the other side of the 1-1 injection hole 140, and the third detection agent is disposed on the other side of the 3-1 injection hole 160. A sensor 430 is formed.

Specifically, the angle of the bottom of the 1-1 injection hole 140 and the 3-1 injection hole 160 is preferably 30 - 45°, which means that when spraying is started toward the vicinity of the fire, the fire extinguishing agent flows from the top to the bottom. This is to ensure that the spray is evenly distributed when falling toward .

At this time, if a fire occurs in the area where the third detection sensor 430 is located, that is, near the lower part of the third detection sensor 430, the first detection sensor 410 detects it and then the 1-1 nozzle 140 ), the fire extinguishing agent is ejected through, and at this time, the fire extinguishing agent ejected through the 1-1 nozzle 140 is ejected in a parabolic curve, making it possible to quickly and accurately extinguish the fire occurring near the lower part of the third detection sensor 430. There will be.

In addition, if a fire occurs in the area where the first detection sensor 410 is located, that is, near the lower part of the first detection sensor 410, the third detection sensor 430 detects it and then the 3-1 nozzle 160 ), the fire extinguishing agent is ejected through, and at this time, the fire extinguishing agent ejected through the 3-1 nozzle 160 is ejected in a parabolic curve, making it possible to quickly and accurately extinguish the fire occurring near the lower part of the first detection sensor 410. There will be.

In other words, different injection ports 100 operate depending on the fire occurrence area to release the fire extinguishing agent, which has the effect of minimizing the intersection area of unnecessary chemical spray that appears in the existing gas-based fire extinguishing agent injection port 100.

Accordingly, not only can the number of fire extinguishing agent discharge nozzles that must be installed in the switchgear be reduced, but also the efficiency of fire extinguishing equipment can be improved by minimizing costs and other losses.

In addition, by forming the 1-1 nozzle 140 and the 3-1 nozzle 160 to have a predetermined angle, fire suppression can be performed more quickly than with conventional mechanical operations.

Next, with reference to FIG. 10, the operation process of the first to third detection sensors 410 to 430 for another embodiment according to the present invention will be described in detail.

First, when a fire occurs inside the subpanel, the first detection sensor 410, the second detection sensor 420, and the third detection sensor 430 begin to detect the fire occurrence area.

When the third detection sensor 430 detects that a fire has occurred near the lower part of the first detection sensor 410, the control unit formed in the third detection sensor 430 transmits the detection information to the power supply unit 500.

At this time, the power supply unit 500 supplies power to the electromagnet coil formed inside the 3-1 injection port 160, and the moving passage 115 is opened to eject the fire extinguishing agent through the 3-1 injection port 160. It will happen.

That is, as described above, the 3-1 injection port 160 is inclined at a predetermined angle, making it possible to quickly extinguish a fire occurring near the lower part of the 1-1.

In addition, if a fire does not occur near the bottom of the first detection sensor 410, but a fire occurs near the bottom of the third detection sensor 430, the first detection sensor 410 detects it.

At this time, the control unit formed in the first detection sensor 410 transmits the detection information to the power supply unit 500, and the power supply unit 500 supplies power to the electromagnet coil formed inside the 1-1 injection hole 140. Then, the moving passage 115 is opened and the fire extinguishing agent is ejected through the 1-1 injection hole 140.

In addition, if a fire does not occur near the lower part of the third detection sensor 430, but a fire occurs near the lower part of the second detection sensor 420, the second detection sensor 420 detects it.

At this time, the control unit formed in the second detection sensor 420 transmits the detection information to the power supply unit 500, and the power supply unit 500 supplies power to the electromagnet coil formed inside the 2-1 nozzle 150. Then, the moving passage 115 is opened and the fire extinguishing agent is ejected through the 2-1 injection port 150.

In this way, different spray nozzles 100 operate depending on the fire occurrence area to release the fire extinguishing agent, which has the effect of minimizing the intersection area of unnecessary chemical spray that appears in the existing gas-based fire extinguishing agent nozzle 100.

In addition, the fire suppression device formed inside the switchgear according to the present invention has the advantage of being able to suppress the fire by constructing a scientific and active mechanism and system within a minimum amount of time.

In addition, even if a fire occurs within the switchgear for various reasons, the effect of suppressing a large-scale fire in advance can be expected by extinguishing the fire as locally as possible.

In addition, it is not limited to dealing with fire accidents that occur in switchboards, but when applied to other fields that are experiencing many difficulties due to fire accidents, it serves as an opportunity to derive methods applied exponentially, thereby improving the method of suppressing fire accidents. It could have a significant impact on improvement and safety.
