| 摘 要： | 用电气几何模型(A-W theory)和EMTP程序定量研究了中国特高压变电站设备的绝缘配合问题。与出厂雷电冲击试验电压波形不同，由绕击雷电侵入波在主变压器上产生的电压波形在波头有高频振荡且波尾时间长。考虑多重雷的绕击雷电侵入波，在线路入口安装瓷柱式避雷器和罐式避雷器可以更好地保护断路器和高抗。 |

| Abstract: | This paper studies the insulation coordination of the UHV substation equipment in China quantitatively using the A-W theory and EMTP analysis method. The voltage waveform on the transformer terminal caused by shielding failure surge has high-frequency oscillation at the front with a long-tailed duration, which is absent in impulse test voltage at factories. Both porcelain and tank type of arresters installed at the line entrance are preferable to fully protecting gas circuit breaker (GCB) and shunt reactor (SHR) from multiple lightning shielding failure surge. |
