| 摘 要： | 通过理论分析表明,由于操作过电压主要产生在高压电动机的相与相之间,而现行的ZnO避雷器皆为星形接线,所以,它对高压电动机相对地的绝缘可起到一定的保护作用,而对相对相之间的绝缘则完全不能进行保护。

| Abstract: | Theoritical analysis shows that switching overvoltage mainly arises between phase and phase, so Y-scheme of ZnO surge arrester can only protect the phase-earth insulation of H.V. motor in some way but not phase -phase insulation. |
