Technical Field
The utility model relates to an electromagnetic lock for an outdoor ring main unit, in particular to a passive electromagnetic lock and live monitoring integrated device.
Background
The outdoor ring main unit is simple and reliable, and is widely used in a distribution network power supply network of a city. A mechanical misoperation prevention device is arranged between a load switch and a grounding knife switch of the outdoor ring main unit, and the misoperation prevention device can reliably prevent various misoperation when the wire is led into a power supply of the ring main unit; however, due to the network connection mode of ring network power supply and hand pulling, the power incoming line of the ring main unit has a lower incoming line, which can cause a major safety accident potential of electrified grounding knife switch in the switch cabinet adopting the lower power incoming line, and at the moment, the error prevention device of the ring main unit can not prevent the malignant misoperation of electrified grounding knife switch, so the operation of the grounding knife switch must be controlled, i.e. when the load switch is opened, whether the cable outgoing line (incoming line) is electrified or not must be judged, and the grounding knife switch is allowed to be switched on only when the cable is not electrified; conventionally, an operation hole padlock of an earthing knife is manually judged by an operator when the earthing knife is operated, and the operation is carried out by unlocking when a cable is out of power.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide a passive electromagnetic lock and live monitoring integrated device which can reduce the possibility of misoperation caused by human error and ensure the operation safety and personal safety of a distribution network.
In order to solve the technical problem, the passive electromagnetic lock and electrification monitoring integrated device comprises a shell, an electrification monitoring part and an electromagnetic lock part, wherein the electrification monitoring part and the electromagnetic lock part are arranged in the shell, the electrification monitoring part comprises output ports K1 and K2 of locking signals and an abc three-phase circuit, the electromagnetic lock part comprises a coil and an unlocking operation end connected with the coil, an unlocking key can be inserted into the unlocking operation end, a change-over switch is arranged between the output ports K1 and K2, and the output ports K1 and K2 are respectively connected to the coil and can be operated by the unlocking key through the state of the change-over switch.
And the abc three-phase circuit is respectively connected with a sensor.
And a power supply battery is arranged in the unlocking key.
The power supply battery is a rechargeable battery.
And a charging circuit for charging the rechargeable battery is also arranged in the unlocking key.
After adopting foretell structure, through the electrified monitoring part and the electromagnetism lock part that mutually support that set up, really solved especially that multiple switch under passive environment is difficult to perfect five-prevention difficulty, to the outdoor looped netowrk cabinet of 10kV commonly used, if: the ABB, the Siemens, the Schneider, the Drifsler and other devices can reliably and forcibly close the grounding switch operation hole without changing a mechanical structure, and the structural design of electricity testing and anti-misoperation unlocking integrated replaces operators to perform misoperation prevention control, so that the possibility of misoperation caused by human error is reduced, and the operation safety and the personal safety of a distribution network are ensured.
Drawings
Fig. 1 is a schematic structural diagram of the principle of the passive electromagnetic lock and the electrification monitoring integrated device.
Detailed Description
The passive electromagnetic lock and the integrated device for monitoring electrification of the utility model are further described in detail with reference to the accompanying drawings and the detailed description.
As shown in the figure, the passive electromagnetic lock and electrification monitoring integrated device comprises a shell 1, an electrification monitoring part 2 and an electromagnetic lock part 3 which are arranged in the shell, wherein the electrification monitoring part 2 comprises an output port K1 and an output port K2 of a locking signal, and an abc three-phase circuit, certainly, the electrification monitoring circuit is also necessarily included, the output port K1 and the output port K2 are both connected with the electrification monitoring circuit, the electromagnetic lock part 3 comprises a coil and an unlocking operation end connected with the coil, an unlocking key 4 can be inserted into the unlocking operation end, a power supply battery is arranged in the unlocking key, an internal change-over switch 5 is arranged between the output port K1 and the output port K2, the change-over switch 5 is controlled to be switched on and switched off by signals output by the electrification monitoring circuit, the abc three-phase circuit is also connected with the electrification monitoring circuit and respectively connected with a sensor 6, and the sensor 6 is used for monitoring whether a main circuit is electrified or not, when the main circuit is detected to be uncharged, the change-over switches of the output port K1 and the output port K2 are controlled to be closed by the electrification monitoring circuit, when abc three-phase electrification is detected, the change-over switches of the output port K1 and the output port K2 are controlled to be opened by the electrification monitoring circuit, the output port K1 and the output port K2 are respectively connected to the coil of the electromagnetic lock part 3, the unlocking operation end is matched with a contact of an unlocking key, power is supplied by a power supply battery carried by the unlocking key, when the unlocking key is inserted into the unlocking operation end, a rear contact forms a power supply circuit, due to the existence of the change-over switches, the coil can work only when the change-over switches of the output port K1 and the output port K2 are closed, and the cabinet door can be opened.
Furthermore, the power supply battery is a rechargeable battery, and a charging circuit for charging the rechargeable battery is also arranged in the unlocking key.
The working principle is as follows:
the cabinet body has the pilot lamp usually, and the pilot lamp is lighted to the low pressure that obtains through the step-down of high pressure sensor's well electric capacity, and when having electricity in the cabinet, the pilot lamp is bright, and when there is not electricity in the cabinet, the pilot lamp is not bright, and has two switches in the electromagnetic lock, and one is the access switch of electromagnetic lock, is mechanical hasp (conventional structure), and the other is the button switch on the electromagnetic lock, and passive electromagnetic lock must two switches all can operate under the condition of opening the position.
When the power monitoring part on the grounding knife switch monitors high voltage, the high voltage comparison circuit can not act (the charged monitoring circuit controls the switch of the output port K1 and the output port K2 to be disconnected), the passage of the electromagnetic lock part can not be opened, at this time, even if the unlocking key is inserted into the electromagnetic lock, the electromagnetic lock cannot be operated, and the grounding knife switch is prohibited from being closed.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
