摘　　要：电流互感器是为电力系统二次设备获取一次回路电流信息的一种传感器,但由于电流互感器常连接在一次回路中,运行时易受各种冲击电压、静电电压、运行电压和潮气等多种不利因素共同作用,存在着绝缘不断降低的危险。A current transformer is a sensor that gets primary current information for the secondary equipment of the power system.But the current transformer is often connected to the primary circuit,it is easy subject to various unfavourable factors of surge voltages,static voltages,working voltage and moisture and so on,leading to insulation to be continuously reduced danger.
