Electrical cabinet electricity-testing misoperation-prevention operating system

Abstract

The invention relates to the field of power electrical technology, and in particular relates to an electrical cabinet electricity-testing misoperation-prevention operating system. The electrical cabinet electricity-testing misoperation-prevention operating system includes a current sensor, a misoperation-prevention electricity-testing host, an electronic key, and an electronic misoperation-prevention lock; the misoperation-prevention electricity-testing host and the electronic key are timely wirelessly connected through a wireless real-time communication unit so that the electronic key instantly receives locking and unlocking information sent by the misoperation-prevention electricity-testing host, when the misoperation-prevention electricity-testing host detects the charged case, it can immediately send a locking information command to the electronic key, and the electronic key cannot open an electronic misoperation-prevention lock. According to the live condition of the line, the misoperation-prevention host determines by itself whether to authorize the unlocking of the key. When the unlocking command is authorized, the line is unexpectedly powered during the unlocking process, and the host terminates the unlocking authorization in real time through wireless communication, which can ensure safety, greatly improve the safety and reliability of operation, and avoid personal injury to operators.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an electric cabinet anti-malfunction operating system for electric cabinets. Background technique [0002] At present, in the field of power distribution network, the five electrical defenses refer to: preventing mis-distribution and mis-closing of circuit breakers, load switches, and contactors; When the switch is in the closed position, close the circuit breaker and load switch; prevent mistaken entry into the electrified room. The five electrical defenses require that the door of the electrical cabinet cannot be opened when it is charged with high voltage, and must be locked forcibly to prevent misoperation. [0003] In order to meet the above requirements, the existing conventional design is to install a live display and an electromagnetic lock on the cabinet door; install a sensor on the high-voltage line in the electrical cabinet to convert the high voltage into a l...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, there may be safety accidents caused by high temperature or short-circuit electrification during the operation of the line, and there may also be cases where the electrified display is not lit due to a fault and the electromagnetic lock has no power supply. In addition, although the existing electronic key unlocking can improve the reliability of unlocking, after the electronic key receives the authorized unlocking command, if the line accidentally calls during the unlocking process, if you continue to unlock at this time, it will Violation of the requirements of the five defenses, resulting in safety accidents, so the existing electric detection lock unlocking technology still has the problem of unreliable use and potential safety hazards
