The Contamination Flashover Analyses Of Electric Network Equipment And The Research Of Monitor Device

The accident that contamination flashover of electric network had made a huge threat on safe work in equipment of network, and economic damage and social influence it aroused is very enormous.Thesis aiming at the condition that large-acreage contamination flashover happened in electric network many times in our country under bad weather, the cause of large-acreage contamination flashover is analyzed from such ways as the insulated level of the power transformation device, air pollution and meteorological factor and so on. We present the configuration principle of the insulated level of the power transformation device and some measures about preventing contamination flashover at present. Aiming at the specially geographical and meteorological condition of Fu-xin city, analyzed the cause of contamination flashover on Chuang-ye transformer substation in Fu-xin. The technical measure against contamination flashover of the power transformation device in electric network in Fu-xin city is studied and determined.And a system of on-line state monitor for the insulator base on the wireless technical GPRS has been developed.
