Maintenance isolation locking system and method

Abstract

The invention provides a maintenance isolation locking system and method. The system comprises a locking operation instruction generation module, a lock-up release instruction sending module and a first unlocking verification module, wherein the locking operation instruction generation module is used for generating a locking operation instruction according to a work task of a lock-up point requiring locking and sending the locking operation instruction to an intelligent key; the lock-up release instruction sending module is used for sending a lock-up release instruction of an isolation lock required to be unlocked by the intelligent key to an isolation lock management box according to the locking operation instruction; the first unlocking verification module is used for verifying whether the isolation lock to be opened by the intelligent key is correct or not according to the locking operation instruction and outputting an instruction for opening the isolation lock after the condition that the isolation lock to be opened by the intelligent key is correct is determined. The method is an informatization management method for realizing implementation, monitoring and dismantling of a maintenance isolation measure through application of the maintenance isolation locking system. Therefore, the management efficiency of the information process of the safe isolation measure as well as the lock in electric power system maintenance can be improved, the isolation lock is effectively prevented from being lost, and safety accidents caused by faulty operation of the isolation lock are prevented.

Description

technical field [0001] The invention relates to the maintenance field of electric equipment, in particular to an isolation and locking system for inspection and an isolation and locking method for inspection and maintenance realized by using the system. Background technique [0002] The power system uses a large number of power equipment and switching devices in the links of power generation, transformation, transmission and distribution, including various insulation devices, isolating switches, circuit breakers, etc. These devices and switching devices need to be checked frequently to ensure that the equipment safe operation, so as to ensure the safe operation of the power system. Since the maintenance process of power equipment and switching devices requires a large number of switching devices to be opened and closed, if the maintenance work is performed without correctly opening and closing the switching devices and forcibly locking the switch state, it will easily lead t...

AI Technical Summary

Problems solved by technology

[0008] However, the management of isolation locks through manual management often leads to untimely and inadequate management of isolation locks, which affects the management efficiency of isolation locks, leads to untimely statistics of unlocking conditions at each locking point, affects maintenance efficiency, and easily leads to opening and closing. Safety accidents due to faulty gate operation
