Abstract

The invention provides a transformer substation grounding grid monitoring system. The transformer substation grounding grid monitoring system comprises an excitation source module, a grounding grid monitoring module and a processing module, the excitation source module is used for injecting an excitation signal with a specified frequency into the grounding grid through the grounding grid down lead; the grounding grid monitoring module is used for acquiring magnetic induction intensity data of a ground surface detection point of the grounding grid after the excitation source module injects the excitation signal into the grounding grid, and transmitting the magnetic induction intensity data corresponding to the detection point to the processing module; and the processing module is used for controlling the excitation source module to inject the excitation signal into the grounding grid, performing grounding grid performance analysis processing according to the received magnetic induction intensity of each detection point, obtaining a grounding grid performance analysis result, and transmitting the grounding grid performance analysis result to the management terminal. According to the invention, remote and online monitoring of the performance of the grounding grid can be realized, the intelligent level of monitoring of the grounding grid is improved, meanwhile, the investment of labor cost is reduced, and the requirements of modern substation safety construction and management can be met.

Description

technical field [0001] The invention relates to the technical field of power station grounding grid monitoring, in particular to a substation grounding grid monitoring system. Background technique [0002] At present, the grounding grid is an indispensable part of substation construction. It is an important link in the lightning protection technology of the substation and also the guarantee for the safe operation of the entire substation. On the one hand, the construction of the grounding grid can provide a zero reference for the electrical equipment in the substation. On the one hand, it provides grounding protection for the metal casing of the electrical device, the structure of the power distribution device, and the line stem tower, and at the same time provides a lightning current discharge channel for the lightning protection device. At present, the substation grounding grid is usually welded into a grid with 5-6cm steel or copper materials and buried underground. Howe...
