用改进的静电探头测量绝缘子表面电荷

Measuring of surface charge of insulator using improved electrostatic probe

设计了用于绝缘子表面静电荷的测量装置。得到了圆柱型绝缘子的表面电荷分布图。实验研究表明设计的电荷测量装置具有分辨力高、电荷泄漏少的优点。

A device used to measure surface charge is designed.Distribution of accumulated charges on the surface of cylindrical insulator stressed by DC voltage is acquired.The test results show that the new type probe is of high resolution with low leakage currents.
