Description

technical field [0001] The invention belongs to the field of transmission line insulator detection and relates to a method for judging the pollution level of transmission line insulators based on a neural network. Background technique [0002] High-voltage transmission lines are responsible for the important task of transmitting electric energy, and their safety and reliability will directly affect the power supply level of the power system. With the rapid development of the power network, the voltage level of the transmission line is getting higher and higher, and higher requirements are placed on the reliability of the power supply of the power company. However, with the continuous increase of atmospheric pollution, the pollution flashover phenomenon of transmission line insulators has become a major hidden danger that threatens the safe and stable operation of the power system. In view of the long-term exposure of insulators to harsh atmospheric environments with severe ...
