不同服役年限下动车组高压隔离开关用绝缘子运行性能研究

open access: yesDianci bileiqi, 2022
随着动车组服役年限的增加,其车顶绝缘子的绝缘性能会发生衰退。为研究不同服役年限下高压隔离开关用绝缘子性能衰退特性,本研究以动车组车顶复合支柱绝缘子为研究对象,对其进行了憎水性、绝缘电阻测试和雷电冲击试验。基于绝缘子憎水性测试,研究表明,服役年限为3年的绝缘子憎水性最好,为HC3级。与服役年限为3年的绝缘子相比,服役年限为4年、5年、6年和10年的绝缘子憎水性普遍下降,均为HC4-HC5左右;基于绝缘子绝缘电阻测试,研究表明,不同服役年限下绝缘子泄漏电流变化不大,均维持在30.6μA~42.0μA ...
