摘要
以挂网运行线路110 k V、220 k V复合绝缘子为研究对象,对其电气、力学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有效评估。结果表明:运行多年的复合绝缘子的电气性能和力学性能仍满足线路运行要求,其老化特征与运行时间之间存在一定的相关性。试验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 composite insulators as research object, we tested their electrical and mechanical properties. On this basis, the operating condition of composite insulators was evaluated effectively. The results show that the electrical and mechanical properties of the composite insulators after operating for many years still satisfy the line operation requirements. The ageing characteristic has some correlation with the operating time of composite insulators. The test results can provide reference for the operation and maintenance of composite insulators.
