500 kV限流用电抗器过电压耐受分析

Gaoya dianqi, 2009
500 kV干式空心电抗器用来限制500 kV系统的短路电流。在制造电抗器前,需要对电抗器的过电压耐受进行评估,保证匝间电压小于绝缘值。笔者在已知电抗器分布参数的基础上,用链型回路等值电抗器,采用PSCAD/EMTDC程序求解在雷电和操作冲击下的匝间电压。计算表明,雷电时外圈首匝匝间过电压最大,可达19.8 kV,操作时首匝匝间过电压最大,可达10 kV,但都小于36 kV的耐受值。

500kV高性能避雷器的开发

Dianci bileiqi, 1991
此避雷器能使雷电和操作冲击过电压迅速对地放电,从而保护电力设备的绝缘。在常规电压下,长期运行及雷电和操作冲击过电压反复放电的情况下,初期,性能不会劣化。基于上述两点,制成了即使在发生内部闪络时充气绝缘罐也不会破坏的结构 ...
