The grounding grid is the first equipment to be constructed when a substation is built. The grounding grid mainly plays a protective role and can effectively ensure the leakage safety of electrical equipment. Most grounding grids are buried underground, which makes the grounding grid corroded by acid and alkali substances in the soil, causing damage to the grounding grid. Therefore, it is necessary to monitor the grounding grid regularly.

In the present invention, the surface of the connecting wire is cleaned.

[0004] However, the above method still has the following defects: a detachable cleaning block is used to effectively remove dust and attached impurities on the surface of the connecting cable; however, in actual operation scenarios, during the winding process of the connecting cable, as the connecting cable is wound and moved, the cleaning blocks in the upper and lower parts are often difficult to remain stable, and are prone to position displacement or even accidental falling off. This unstable state interrupts the continuity of the connecting cable cleaning process, thereby reducing the overall cleaning effect. Summary of the invention

[0005] The purpose of the present invention is to provide a grounding grid corrosion monitor to solve the problem in actual operation proposed in the above background technology that the detachable cleaning block is prone to become unstable due to movement when the connecting line is wound, causing the upper and lower cleaning blocks to shift or fall off, affecting the cleaning continuity and reducing the overall effect.
