Ground wire hanging anti-error blocking system and method thereof

Abstract

The invention discloses a ground wire hanging anti-error blocking system and method. The system disclosed by the invention mainly comprises a ground wire hanging inductor, a ground wire electronic signboard, a ground wire signal acquisition unit, a ground wire management terminal, a ground wire signal fail-safe interface machine and a dispatching (centralized control station) anti-error monitoring terminal. According to the method disclosed by the invention, by utilizing the system disclosed by the invention, ground wire hanging state detection and hanging anti-error blocking can be carried out through devices and programme software in the invention; functions of detection, storage, analysis, display, inquiry and blocking signal output in a use state and a hanging state of the ground wirecan be realized; the system and the method disclosed by the invention can be widely applicable to the ground wire management and hanging anti-error blocking in equipment overhaul places, such as power stations, converting stations, distribution substations and the like; and electric equipment and worker safety are ensured.

Description

technical field [0001] The invention belongs to the technical field of electric power system substation inspection and maintenance safety maintenance, and in particular relates to the anti-mis-detection management of grounding wire connection and the improvement method of the five-prevention system. Background technique [0002] The safe and reliable operation of the power system is related to all levels of the national economy, and the safe and reliable operation of substations is the most important. The safe operation of power systems and substations requires the protection of equipment and personal safety during operation. [0003] During substation maintenance, in order to protect the safety of operators, it is necessary to adopt the technology of temporary grounding wire. The temporary grounding wire is hooked to the grounding pile buried in the ground at one end, which is used to guide the current into the ground when there is a leakage, so as to ensure the safety of w...

AI Technical Summary

Problems solved by technology

[0011] In view of the deficiencies in the prior art above, the technical problem to be solved by the present invention is to overcome the problem that the existing "five defenses" system cannot solve the problem of safe disassembly of the temporary grounding wire, and the existing "five defenses" system cannot be used for the safety of equipment maintenance. Monitoring, grounding wires and the working status of the "five-defense" system itself cannot be fed back to the dispatcher, so that the dispatcher cannot fully grasp the on-site situation, which may lead to problems such as wrong orders, and provide a grounding wire hooking anti-misoperation locking system and the method thereof, realize the detection and monitoring of the use state and the connection state of the temporary ground wire, and connect the detected signal with the existing five-prevention system of the substation, and automatically generate a signal for locking or opening the switch operation according to the connection situation of the ground wire, And send it to the five-proof interface machine, and the five-proof system will complete the locking or unlocking of the relevant switch operations
