Pollution Flashover Characteristics of Composite Insulator with Joint Insulation Jacket at Transmission Conductor Near Its High Potential End
摘要
Abstract
The method of installing insulation jacket on transmission line conductor can improve the electric field strength of high potential side of composite insulator,but the influences of composite insulator on pollution flashover characteristics have not been made a detailed study until today.In this article,the physical model of composite insulator with insulation jacket was studied in the case of wet contamination,the effects of insulation jacket parameters were analyzed and the conclusion that installing the optimization parameters insulation jacket on transmission line conductor can improve the pollution flashover characteristics of composite insulator was drawn.Furthermore,the correlation between the insulation jacket＇ length and the contamination flashover voltage of composite insulator was obtained by the artificial test.Based on the test results,the optimization insulation jacket parameters are suggested and the relationship curve of contamination flashover voltage of composite insulator installed the suggested insulation jacket and the equivalent salt deposit density（ESDD） was also given.The insulation jackets manufactured according to the optimization parameters were installed onto the transmission line conductor in the field.During one year of operation,the positive effects on the electric field distribution and the reliability of the installed insulation jackets have been confirmed.关键词
