A mistaken lock prevention ground line control system and control method

Abstract

The invention provides a misoperation-proof locking earth wire control system and a control method with convenient construction and management, which can avoid the misoperation, and can effectively conduct assemble and disassemble management of the temporary earth wire and real-time radio signal communication. The misoperation-proof locking earth wire control system comprises a temporary earth connection device and a five-prevention main machine, the temporary earth connection device comprises an earth wire clamp, a cable, as well as an earth wire pile head; the earth wire clamp comprises an earth wire connecting device can conveniently conduct connection and dismantlement with a power transmission line and a cable clamp device connected with an earth wire cable, wherein, the earth wire clamp is also arranged with a controller circuit that can detect whether the power transmission line exists and can outwardly transmit the detected signals, and the controller circuit is sealed and packaged on the earth wire connecting device; the five-prevention main machine comprises a misoperation-proof locking judgment module and a wireless signal transceiver module.

Description

technical field [0001] The invention relates to a control system and a control method for an anti-misoperation locking ground wire, in particular to a control system and a control method for preventing electrical misoperation used in a power system for judging the working state of a temporary ground wire. Background technique [0002] The "five-prevention" locking system is a control system for my country's power system to prevent misoperation of switching during power transmission and distribution in power plants and substations. Pull and close the knife switch with load, prevent the live wire from hanging the ground wire, and prevent the knife switch from being connected with the ground wire. Over the years, the switching misoperation has repeatedly caused serious accidents in the power system, especially for the misoperation of the live wire hanging on the ground and the grounding wire closing the knife switch. Due to the incomplete management of the installation and disas...

Problems solved by technology

At present, most of the temporary grounding lines use printing or numbering to identify the different grounding lines, but there is a lack of technical means to allow the five-proof host or other automation systems to identify and manage the grounding lines, let alone real-time monitoring at the application site Check and manage the connection and removal of temporary grounding wires, especially for the removal of grounding wires after the electrical equipment is overhauled. Unremoved ground wires will cause serious misoperation accidents, resulting in huge equipment losses and economic losses
