摘要
分析了实际运行中的4起复合绝缘子发生事故的原因,说明复合绝缘子端部联接金具的结构形成对复合绝缘子的运行寿命有重要影响。复合绝缘子对两端联接金具的要求不应与盘式绝缘子相同,但目前使用的复合绝缘子都采用盘式瓷绝缘子的端部金具联接形式,因而带来隐患。
The paper analyzed the reasons of 4 faults of composite insulator in actual operation, and explained that the configuration of connection fittings for end of composite insulator has important influence on operation life of composite insulator. The requirements of connection fittings for two ends of composite insulator should not be same for the disk type insulator, but now, the connection fittings used for end of composite insulator are same with that for disk type porcelain insulator, which brings hidden trouble.
