| 摘 要： | 克尔效应(Kerr Effect)作为一种电光效应,主要表现为:克尔介质在外加电场作用下,会使得入射到其中的探测光带有外加电场的信息.基于上述原理,设计并搭建了由快脉冲高电压源、YAG激光器、同步控制子系统、被测绝缘子及克尔效应单元、相位差检测子系统构成的真空绝缘子表面电场在线测量实验平台.通过对比性测量,观察到了真空绝缘子沿面带电导致的表面电场畸变现象.并进一步对绝缘子表面电场的畸变进行了时间分辨测量.

| Abstract: | Kerr effect is defined as an electro-optical physical phenomenon, in which the testing laser can change its polarization state as passing through a Kerr medium stressed by applied field. In this work, an on-line measurement system based on Kerr effect is established to investigate the surface electric field of insulator stressed by nanosecond HV pulse in vacuum which include a HV pulse source, YAG laser, synchronous controlling apparatus, Kerr cell & insulator sample, optical phase shift detecting subsystem. According to comparison experiments, the distortion of insulator surface electric field caused by surface charging is observed. And a time-resolution measurement on this field distortion is also performed.
