| Abstract: | A case of 500kV composite insulator outer sheaths was damaged in Shandong Power Grid is introduced through the infrared measuring temperature measurement. The damage reasons are analyzed,this paper expounds the electrical test technology in the diagnosis of composite insulator infrared measuring temperate discriminate method,the mechanism of internal defects. The results of infrared temperature measurement and the laboratory experiments show that the infrared imaging method can effectively detect the defect of composite insulator. At last, the measures and the suggestion are presented to improve the level of safe operation of the composite insulator. |
