运用于现场大容量GIS陡前沿冲击可调波尾电阻装置
本技术涉及运用于现场大容量GIS陡前沿冲击可调波尾电阻装置。
技术介绍
电力系统中的高压电气设备在投入运行之前需要进行冲击电压试验来检验其在过电压作用下的绝缘性能。冲击电压发生器主要用于电力设备等试品进行雷电冲击电压全波、雷电冲击电压截波和操作冲击电压波的冲击电压试验,检验绝缘性能。冲击电压发生器波头电阻和波尾电阻,它们相当于各级rf和rt的总和,即Rf=nrf,Rt=nrt,在级数较多的冲击电压发生器中,冲击电压发生器更换波头波尾电阻的方式都是采用人工频繁的取换电阻,取换电阻时间花费较长,效率较低,同时还需准备大量的电阻已备更换,大大增加了成本,在更换电阻时还容易引起人身事故。
