冲击电压发生器同步特性的改善措施

Improvement on Synchronism Characteristic of Impulse Voltage Generator

试验研究了冲击电压发生器的同步特性 ,提出了改善冲击电压发生器同步特性的 3项措施。一台 2 4级冲击电压发生器 ,改善后的同步特性范围在 2 5 0 0 k V雷电冲击电压下提高～ 40 % ,在 35 0 0 k V下雷电冲击提高～ 2 0 % ;在 130 0 k V(2 5 0 /2 5 0 0 μs)操作冲击下提高～ 2 5 %。

With a new 4 800 kV impulse generator, the synchronism characteristics are analyzed and investigated by experiments. Three measures to improve such performance are introduced. The results show that the synchronism range increases greatly with these measures. It reaches 40% at the output voltage of 2 500 kV, and 20%of 3 500 kV.
