摘　　要：分析了广东佛山供电局220kV和北京超高压公司500kV故障复合绝缘子的红外测温结果,说明红外测温技术能够实现远距离、大面积快速扫描,是发现复合绝缘子内部缺陷的有效手段。同时将红外测温结果和电场分布测量结果进行了比较,表明红外测温技术可以发现局部发热的内绝缘缺陷,电场分布测量法可发现导通性通道的内绝缘缺陷。The result of inffrared temperature measurement for composite insulators m 220 kV fault m Guangdong Foshan Power Supply Bureau and m 500 kV fault m Beijing UHV Co. was analyzed. It is explained that infrared temperature measurement technology is the effective means to discover the internal defect of composite insulator and can realize fast scanning h long distance and large area. At the same time, the results of infrared temperature measurement and electric field distribution method were compared. It is shown that infrared temperature measurement technology can discover the internal insulation defect h local heating, and electric field distribution method can discover the internal insulation defect m conduction channel
