The electric power conductive paste is applied to the field of electric power equipment connection contact coating. The connectivity of the power equipment is an important factor for the safe operation of the power grid, and is a key for reducing the connection heating faults of the power equipment. The electric conductive paste is an electric contact coating with good electric performance, is suitable for coating copper-copper, copper-aluminum and aluminum-aluminum faying surfaces, and can prevent oxidation and galvanic corrosion phenomena of the faying surfaces caused by the corrosion of atmosphere and corrosive agents, thereby stabilizing the contact resistance of the contact points and reducing the connection heating. As the connection point of the electric power equipment in operation is easy to swing by wind power and electric vibration, the connection point is loose and conductive paste falls off, so that the contact resistance is increased, and the connection point heats. Although the traditional electric conductive paste in the prior art can eliminate invisible electric gaps, the contact is tighter, and heating is reduced, when large electric gaps are filled in a blocky manner, the traditional electric conductive paste does not have conductivity, cannot be charged for secondary filling of heat defect elimination, and the traditional pure charged fastening defect elimination effect is poor and the danger coefficient is high, so that the number of electric defect elimination items caused by stopping heating is increased.
In order to ensure the safe operation of power grid equipment, reduce the thermal fault of equipment connection, relieve the workload of heat elimination and the power failure pressure caused by power failure elimination, develop the conductive paste coating which is suitable for filling large electric gaps in various climatic environments and has excellent conductivity, quick solidification, strong adhesiveness and strong adhesiveness, and become the problem to be solved urgently, so the technical research on the conductive paste coating block filling conductivity, quick solidification, adhesiveness and adhesiveness is particularly important.
