摘要
在切、合空载线路时产生的过电压,是由于系统内部电磁能量的变换,传递和积累引起的。如不加以限制将产生很大数值,这种过电压将对线路的绝缘产生很大的冲击,甚至击穿整个系统的绝缘,造成供电系统瘫痪。
In the cutting, together no- load line produced by over- voltage, is due to electromagnetic energy within the system transformation, transmission and accumulation, If not restrictions will have a great value, Such over-voltage insulated lines will have great impact ono Even insulation breakdown of the system, Power supply system caused by paralysis.
