Grounding wire management operating system

Abstract

The invention relates to a grounding wire management operating system for connecting a substation and a power plant with a microcomputer five-prevention system and carrying out the safe standardized administration of grounding wire access. The microcomputer five-prevention system is connected with a communication circuit through a grounding wire cabinet monitoring system and transmits a right operation ticket to a computer key through an adaptor, the computer key operates an electric coding lock control mechanism which is communicated with a contact detection circuit, the computer key is respectively connected with a clock circuit, a data memory, a nixie tube driving circuit, a telecommunication circuit and a contact detection circuit, an alternating current power supply supplies power to the clock circuit, the data memory, the nixie tube driving circuit, the telecommunication circuit and the contact detection circuit by a power supply module (1) through a microprocessor, and the alternating current power supply supplies power to the electric coding lock control mechanism through a power supply module (2). The invention supports the integrated application of the grounding wire management and the microcomputer five-prevention system, ensures the whole grounding wire access process to accord with the operation flow, eliminates the hidden danger of serious accidents and improves the modern management levels of the station and the plant.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a grounding wire management operating system used in substations, power plants, etc., which is linked with a microcomputer five-proof system and performs safety and standard management on the access of ground wires. Background technique [0002] The microcomputer five-proof system is composed of five-proof computers, computer keys, adapters, mechanical coded locks, electric coded locks and other functional components. The electrical primary wiring diagram of the substation (power plant) and the operating rules of the equipment are pre-edited in the system software. When the operator performs a simulated preview operation on the anti-mistake software of the computer (simulation screen), the anti-mistake computer will lock the system according to the pre-edited The relationship judges each operation, refuses to execute the operation that violates the "five preventions" principle...

AI Technical Summary

Problems solved by technology

According to the latest statistics of the State Grid Corporation of China, the vicious accident with grounding wire (grounding knife switch) closing ranks first in various misoperation accidents, and most of these accidents are caused by misoperation of the grounding wire and lack of safety supervision. Caused, concentratedly reflecting problems such as imperfect organization and management measures of grounding wires or lax implementation
