摘要
在电力供电电网上,过电压现象十分普遍。如果没有防范措施,随时都可能发生过电压现象。引起电网过电压的原因有很多,主要可分为谐振过电压、操作过电压和雷电过电压。
Power supply system or electrical power supply line, over - voltage phenomenon is very common . If there are no preventive measures, could happen at any time. Over - voltage of power grid causes by many reasons. Can be divided into resonance over- voltage, operation over- voltage and lightning over- voltage .
