The layout principle of each device in the fire fighting system is comprehensively considered according to the device layout of the converter station.
The control process of the control system provided by the embodiment is as follows:
as shown in fig. 3, firstly, the system is powered on, and initialization operations such as self-test are performed on the system device; then the fire alarm system starts to monitor fire alarm, if the fire alarm is monitored, whether fire extinguishing system starting logic is met is judged, if the fire extinguishing system starting logic is met, a monitoring system camera is controlled to aim at a fire point, the fire fighting robot system sends out the fire fighting robot to detect, if the fire extinguishing system does not meet the starting logic, the system confirms the fire condition through the monitoring system and the fire fighting robot system, if the fire condition is not confirmed, the system informs operation and maintenance personnel of confirming the fire condition, after the fire condition is confirmed, the system informs a station-parking fire fighting team to prepare fire extinguishing work, starts a fire fighting robot fire extinguishing program, starts a current conversion variable spray fire extinguishing system, and starts a fire monitor system.
In the fire extinguishing process, the control system comprehensively judges and controls the corresponding opening and closing of each subsystem according to various information collected by the sensors of each subsystem, and operation and maintenance personnel can participate in control according to various data.
After the fire is over, all system equipment resets, and the fire-fighting robot returns.
It should be noted that:
1. at present, the fire control subsystem (spraying system) that the change of current becomes to arrange on every side starts to have current logic, when taking place the fire alarm, accords with current logic and opens this subsystem promptly, but can't start the fire monitor system, and there is the blind area in current logic, can't accomplish to cover comprehensively. If the existing logic judgment fails, namely the subsystem cannot be started, the first time of fire extinguishing and suppression is missed when the operation and maintenance personnel realize the problem and open the deluge valve on site, and the subsequent influence is great.
The monitoring system and the fire-fighting robot are added to participate in logic judgment in the embodiment, as shown in fig. 4, wherein the monitoring system 101 comprises a plaza camera and a valve hall cornice camera, and the fire-fighting robot is arranged near a converter transformer on a plaza. The existing logic, the monitoring system and the fire-fighting robot can perform multiple judgments, so that all fire-fighting systems can be started at the first time.
2. At present, the fire extinguishing systems that change of current transformer disposed includes atomizing system, fixed fire gun system etc. and atomizing system sets up at change of current transformer near position all around, can carry out the total flooding cover to change of current transformer basically, and fixed fire gun system sets up at far away end, and it puts out a fire to change of current transformer near the top position through high-pressure injection. Through many experiments, the spraying system has a good fire extinguishing effect and is configured as a main system, and a fixed fire monitor system is configured as an auxiliary fire extinguishing system.
The spraying and fire-fighting gun can independently extinguish the transformer fire, and when the same medium is used, the spraying fire-fighting time is shorter
The fire extinguishing medium used in the current converter station is generally water or foam, and the fire water supply system supplies water to the spraying system and the fire monitor at the same time.
If the fire water supply system has sufficient water supply flow, it is sufficient to supply both the spray system and the fire monitor system.
When spraying system and fire gun use same medium, this patent can select the very first time to start spraying system and fire gun simultaneously.
When the spraying system is used for extinguishing fire, and the fire monitor is used for extinguishing fire, if the spraying system and the fire monitor are simultaneously opened, the water spray can disperse the foam injected by the fire monitor. When the mist system extinguishing medium is foam and the fire monitor extinguishing medium is water, the water monitor may break the foam mist if the mist system and the fire monitor system are turned on simultaneously. Both of these conditions result in a reduction in the fire fighting effect. So when spraying system and fire gun adopted different fire extinguishing medium, only started single system, according to above-mentioned experimental result, this patent can select very first time to start the main system, also is spraying system, and fire gun system is supplementary as reserve.
At present some fire control water supply system of converter station supply water flow is not enough, only when enough starting single system, according to above-mentioned experimental result, the very first time of this patent can be selected and the main system is started, namely spraying system, and the fire monitor system is supplementary as reserve.
When the spraying system is started at the first time and the fire monitor system is not started, a situation may occur that the spraying system is in close proximity to the converter transformer, the converter transformer explodes and catches fire or the high-temperature combustion for a long time may cause damage to a nozzle or a pipeline of the spraying system, and the spraying system is depressurized, as shown in fig. 5.
Therefore, the spraying system can be selected to be closed when the spraying system is in a pressure loss state, the fire monitor system is started, the channel of the fire water supply system to the spraying system is closed, the fire water supply system is enabled to independently supply the fire monitor system, and the pressure of the fire monitor is guaranteed.
3. Another difficulty in fire fighting in the converter station is that a large number of live equipment are contained in the station, when one converter transformer is on fire, even if the non-electric protection action trips, the group of converter transformers are tripped, and a large number of live equipment exist nearby, so that fire fighting and rescue are affected to a certain extent. At present, only a circuit breaker disconnection signal of a converter transformer is connected into a starting logic of a spraying system, state information of a rear self device and adjacent equipment is not connected, and a commander in a central control room needs to consider a fire-fighting system and an original electrical system at the same time, so that fire emergency is seriously influenced. It is considered that these signals also affect the subsequent fire fighting system start-up and rescue command. This patent will change the electrical quantity information of flow and adjacent equipment and all insert, join simultaneously and judge the logic.
The transformer contains a large amount of insulating oil inside, satisfies the insulating requirement of inner structure, if carry out emergent oil extraction in electrified state, will cause the large tracts of land to discharge because of the lack of insulating oil, causes the result that can't imagine. For solving this problem, this patent judges just can start emergent oil extraction system under the condition of converter transformer outage, ensures the safe oil extraction of transformer, reduces the control of converter transformer conflagration and the degree of difficulty of putting out a fire.
Even if the converter transformer is powered off, under the condition that the converter transformer and adjacent equipment thereof are not overhauled, a fire rescue troop still has great risk of entering a field for rescuing. For example, the telescopic arm of a high-speed vehicle is likely to cause the induction discharge to cause injury to the vehicle and personnel during the extension process. In order to solve the problem, the gate system is opened under the condition that the converter transformer is judged to be changed to be overhauled, a station fire brigade is informed to enter the fire extinguishing, and the valve hall roof cooling system is started simultaneously.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
