Management control system and method for preventing error operations of electrical secondary equipment

Abstract

The invention provides a management control system for preventing error operations of electrical secondary equipment. The system comprises a master control device, a computer key, a resident lock and a temporary lock, wherein the master control device is used for receiving set information and generating an operation order according to the set information; the computer key is in communication connection with the master control device and is used for receiving the operation order transmitted by the master control device; the resident lock and the temporary lock are in communication connection with the computer key; the resident lock is mounted on normally closed lock equipment needing to be subjected to resident locking; the computer key controls the resident lock to execute operations according to the operation order; the temporary lock is mounted on temporary locking equipment needing to be subjected to temporary locking; and the computer key controls the temporary lock to execute operations according to the operation order. According to the resident lock and the temporary lock, hierarchical management control of the electrical equipment is realized, the condition that accidents are caused by error operations of the electrical equipment is effectively avoided, and the safety in the plant-station production operation process is improved.

Description

technical field [0001] The invention relates to the technical field of operation safety control of factories and mines, in particular to a control system and control method for preventing misoperation of electrical secondary equipment. Background technique [0002] The power system uses a large number of electrical primary and secondary operating equipment in the links of power generation, power transformation, power transmission, and power distribution, including electrical primary equipment such as circuit breakers, isolating switches, and grounding switches, as well as pressure plates, secondary switches, and buttons. The switching operation of such primary and secondary electrical equipment during operation and maintenance will directly affect the operation safety of the power grid and the personal safety of operators and maintenance personnel. [0003] In order to prevent the occurrence of electrical misuse accidents and ensure the safety of people, power grids and equi...

AI Technical Summary

Problems solved by technology

The safety technical measures for secondary equipment are mainly to hang signs and install barriers (fences) during maintenance operations. This technical measure cannot prevent the secondary switch from missing closing and opening, the air switch from being wrongly closing and opening, and the pressure plate from being thrown incorrectly. , wrong return, wrong connection of current terminals and wiring, wrong touch and other misoperations
