输电线路复合绝缘子的电气及机械特性

Electrical and Mechanical Performance of Transmission Line Composite Insulator

以挂网运行线路110 kV、220 kV复合绝缘子为研究对象,对其电气、机械性能进行了试验检测;在此基础上对复合绝缘子的运行状态进行了有效评估。结果表明,运行多年的复合绝缘子,其电气和机械综合性能仍基本满足线路运行要求,老化特征与其运行时间之间存在一定的相关性。试验研究结果可为复合绝缘子的运行和维护工作提供参考。

Taking 110 kV and 220 kV operation line composite insulators as research objects, the electrical performance and mechanical performance were investigated in this paper. On this basis, the con-dition of running composite insulator was effectively evaluated. The results show that the electrical and mechanical properties of the composite insulators running for many years are still eligible for the basic requirements of operation line. The aging characteristic of composite insulators has some correlation with the running time. The test results can provide a reference for the operation and maintenance of composite insulators.
