Description

technical field [0001] The invention belongs to the field of coatings for power grids, and relates to grounding grids, in particular to a conductive anti-corrosion coating for power grid grounding grids and a preparation method thereof. Background technique [0002] With the large-scale construction of my country's power grid, substations have sprung up on the land of China like mushrooms after rain. In order to ensure the safe use of various electrical devices in substations, it is necessary to ground these devices. The purpose of grounding is to use the ground as a conduction current. A component of the circuit, so that the potential of the electrical connection is fixed within a certain allowable range under normal conditions, accidents or lightning strikes, so as to ensure the safety of people and equipment, and maintain the safe and reliable operation of systems and facilities. [0003] The grounding grid is an indispensable and important device in the power grid system ...
