摘　　要：避雷器在变电站交接试验中开展持续运行电压下的持续电流试验,由于避雷器还未接入电网无法取得持续运行电压,需要人为对其施加持续运行电压。750kV电网中避雷器工频运行电压高,满足此电压的工频试验变压器存在运输不便问题,交接试验可采用串联谐振方法对其施加持续运行电压。The lightning arrester carries out the continuous current test under the continuous operating voltage in the substation handover test.Because the lightning arrester has not been connected to the power grid and can not obtain the continuous operating voltage,it is necessary to artificially apply the continuous operating voltage to the arrester.The power frequency operation voltage of lightning arrester in 750kV power grid is high,and the power frequency test transformer satisfying this voltage has the problem of transportation inconvenience.Therefore,the series resonance method can be used to apply continuous operation voltage to it in the handover test.
