The Experimental Study of Vibration in Exclosure of GIS by Internal Partial Discharge.
摘要
本文实验研究GIS盆式绝缘子局部放电引起的壳体机械振动
采用压电式加速度传感器及电荷放大器可在低干扰环境下测出局部放电信号
信号的大小与局部放电量及放电重复率均有关
Abstract
This paper investigates experimentally the mechanic vibration in the enclosure of GIS caused by partial discharge of basin insulators. By means of piezo-electric acceleration sensor
the signal due to internal partial discharge can be detected under low noise condition.The amplitude of signal is related to the apparent charge and the repetition rate partial discharge as well.
