Dianci bileiqi在极端强降雨条件下，输电线路、变电站及换流站中的绝缘子伞裙间距因密集的雨柱而被连接，这一现象会显著改变原有电场分布，造成电场畸变。瓷质绝缘子作为电力系统常见绝缘元件，在长期服役过程中，不仅需承受自身重量，还不断受到风力等外部载荷的作用，这些因素作用下，逐渐导致陶瓷内部绝缘性能的退化，进而形成零值绝缘子。为研究强降雨条件35 kV绝缘子串雷电冲击放电特性，针对输电线路复合绝缘子及U70BP/146D瓷绝缘子串不同零值情况开展雷电冲击放电特性测试。结果表明 ...

Gaoya dianqi, 1986 在压缩气体绝缘的输变电设备中,通常会受到金属性粒子的污染而大大地损害其绝缘强度。大量的实验表明:用绝缘膜复盖电极不仅能改善设备中气体的绝缘性能,而且也能提高激发导电粒子所需的电压。本文总结了近十年来在压缩气体绝缘设备中,采用绝缘膜来提高其绝缘强度的研究情况。
