Abstract

The phenomena of surface charging are investigated using the capacitive probe method. In order to decrease the charge leakage a new type probe with high resolution is designed. The influence of voltage amplitude, duration, polarity and surrounding humidity on the surface charging are studied. The accumulation competition between positive charges and negative charges is observed. The experimental results show that at different places on the insulator surface the surface charging has different saturation time constants.

直流电压下绝缘子表面电荷积累

用电容探针法研究了表面充电现象。为了减少电荷泄漏，设计了一种新型的高分辨率探头。研究了电压幅值、持续时间、极性和周围湿度对表面充电的影响。观察到正电荷和负电荷之间的积累竞争。实验结果表明，在绝缘子表面不同位置，表面充电具有不同的饱和时间常数。
