Device and method for monitoring state of grounding wire in transformer substation overhauling operation

Abstract

The invention provides a device and method for monitoring the state of a grounding wire in transformer substation overhauling operation. The device comprises an RFID electronic tag and an intelligentgrounding wire pile. The RFID electronic tag is fixed to the grounding wire and wirelessly connected with the intelligent grounding wire pile. The intelligent grounding wire pile is wirelessly connected with a portable mobile terminal. The portable mobile terminal is wirelessly connected with a monitoring platform. The problems that sometimes a large number of temporary grounding wires are used inthe outage repairing operation process in the prior art, assembling sites are dispersed, management is quite inconvenient, and detachment omission quite easily happens during grounding wire detachment by operators due to high-intensity work, so malicious misoperation events happen to a circuit breaker and a disconnecting switch with a grounding wire are solved.

Description

technical field [0001] The invention belongs to substation maintenance technology, and in particular relates to a monitoring device and a monitoring method for the status of grounding wires in substation maintenance work. Background technique [0002] Temporary grounding wires are the focus and difficulty of substation management. Standardize the management of grounding wires to prevent manual operation errors and improve the management level of substation grounding wires. The grounding wire should complete the following functions during the line construction and maintenance of the power system: the grounding wire should be reliably grounded to ensure the safety of power distribution equipment and construction personnel; the grounding wire should be connected to the determined grounding pile to ensure the corresponding relationship; It is a safety protection device to ensure the personal safety of on-site operators. The operation of installing and disassembling the grounding...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a monitoring device and monitoring method for the status of grounding wires in substation maintenance operations, so as to solve the problem that sometimes a large number of temporary grounding wires are used during power outage maintenance operations in the prior art, and the installed The location is scattered, which is extremely inconvenient to manage. The high-intensity work can easily cause the operator to miss the removal of the grounding wire, resulting in vicious misoperation accidents such as closing the circuit breaker and isolating switch with the grounding wire.
