Overhauling isolation management system

Abstract

The invention discloses an overhauling isolation management system. The system comprises an overhauling isolation manager and an overhauling isolation authorization key, wherein the overhauling isolation manager is used for determining isolated and locked target equipment according to an overhauling isolation task, associating the overhauling isolation task for the only designated overhauling isolation authorization key and distributing an unlocking authority of an isolation locking state of the target equipment for the designated overhauling isolation authorization key; and the overhauling isolation authorization key is connected to the overhauling isolation manager and is used for unlocking the isolation locking state of the isolated and locked equipment corresponding to the associated overhauling isolation task. The overhauling isolation manager distributes the unlocking authority of the locked and isolated equipment for the overhauling isolation authorization key. In an anti-error system, the equipment to be overhauled is isolated and locked and then overhauling personnel uses the only overhauling isolation authorization key to unlock and maintain the equipment; the equipment in an overhauling state is locked to the outside world and can not operate so that the a condition that power transmission is generated by mistake when the overhauling personnel overhaul the equipment is prevented and work safety of the overhauling personnel can be effectively guaranteed.

Description

technical field [0001] The invention relates to the field of substation safety assurance, in particular to a maintenance isolation management system. Background technique [0002] At present, the power plant mainly uses the management method of "work ticket + on-site safety isolation measures" to ensure the operation safety of the maintenance site, but this method has some potential safety hazards: [0003] 1. The disclosure of security measures and the arrangement of security isolation measures for work tickets depend on the responsibility and technical level of the operators, which is highly subjective and lacks rigid constraints on management measures; [0004] 2. During the maintenance period, the authority to maintain and repair the isolation equipment is still in the hands of the operator, and there is a possibility that power can be sent to the maintenance equipment by mistake after a simulated operation, and there is no restriction on the operation rights of these eq...

AI Technical Summary

Problems solved by technology

[0002] At present, the power plant mainly uses the management method of "work ticket + on-site safety isolation measures" to ensure the operation safety of the maintenance site, but this method has some potential safety hazards:

[0003] 1. The disclosure of security measures and the layout of security isolation measures for work tickets depend on the responsibility and technical level of the operators, which are highly subjective and lack rigid constraints on management measures;

[0004] 2. During the maintenance period, the authority to maintain and repair the isolation equipment is still in the hands of the operator, and there is a possibility that power can be sent to the maintenance equipment by mistake after a simulated operation, and there is no restriction on the operation rights of these equipment;

[0005] 3. The work ticket adopts the method of "one job, one ticket", which lacks effective management methods for cross-overhaul operations on multiple working faces, and there is a possibility of wrongly sending power to the overhaul equipment

[0006] Since the safety of the maintenance personnel is mainly ensured through management means, there is a lack of rigid technical measures to restrict, and there is a possibility of wrongly sending power to the maintenance equipment. Once the operator is negligent or the cross-operation of multiple teams is not properly organized, it may lead to accidents of power transmission to the maintenance equipment by mistake. happened

Cannot really and effectively guarantee the safety of maintenance personnel
