Abstract

Due to long-term exposure to the atmosphere, the solid suspended particles in the air will deposit on the surface of the insulator to form a pollution layer. When encountering humid weather conditions, the pollution layer will form a thin conductive layer when it is damp, which will reduce the insulation level of the insulator and result in a pollution flashover. Pollution flashover seriously threatens the safe and stable operation of the power grid. It not only has a wide range of impact and a long duration, but also causes serious economic losses. In-depth research on insulator pollution and monitoring methods, and the design of online monitoring equipment for pollution discharge based on voiceprint technology is of great significance to suppress pollution flashover accidents. Based on the phenomenon that the pollution discharge of insulators is accompanied by acoustic emission, this paper designs a voiceprint recognition intelligent online pollution discharge monitoring device, which can accurately and effectively collect the insulator discharge sound signal, make judgments on the pollution status of the insulators, and reduce the occurrence of pollution flashover trip faults.
