一种特殊结线操作过电压的动模实验和抑制措施

Physical Model Recovery of Switching Overvoltage

针对限流电抗器并联旁路开关结线系统的操作过电压，通过动模实验复现了过电压现象，用光线录波器记录过电压脉冲获得过电压波形的参数，并对并联氧出辞避雷器、电阻和电容等措施进行了试验。实验结果与理论分析一致、为改进结线、消除过电压危害提供了可靠的实验依据。

?This paper presents physical model test results of recovery of switching ovcrvoltage of substation s where reactance paralleled by breakers. The ovcrvoltage pulse and its parameters are shown according to records. At last some restrain methords are tested, such as paralleling zine-oxide-lightning arresters, resistors, or capacitors. Results are concerted with theoretical analysis. So it provides guidance to applied networks.
