纳米晶电力用电流互感器磁芯Power nano crystalline current transformer core电力系统电流互感器的重要作用就是当其初级有交流电流输入时，其次级按比例输出电流。通常，它们应用于高压、大电流发电厂和变电站安全快捷的测量和继电保护。电流互感器使测量和控制电路与被测量的高压电路安全的分开。铁基纳米晶合金互感器磁芯应用于0.2、0.2s、0.1精度等级的精密电流互感器，环氧灌封套管式电流互感器，气绝缘或油浸开关设备，低压、中压、高压开关设备，电力系统、动力系统、继电保护、电能监控装置等    The most important function of power nano crystalline current transformer core is that when there is exchange current inputting in the primary side, there will be current output in the secondary side according to the ratio. Usually, power nanocrystalline current transformer cores are used in high voltage, high current generator factory, safe-quick measurement and protective relaying in power station. The core is widely used in high accurate current transformers, epoxy embedment type current mutual inductor, oil-immersed switch, low voltage, mid voltage, high voltage switch device, power system, generator system, relaying protection, power controlling device, etc.◆ 应用领域Application fields 用于输变电线路测量和监控电流和电能，可满足精度为0.5、0.5S、0.2、0.2S、0.1级互感器的要求。Used in measuring power transmission distribution circuit and monitoring current and energy power.  Able to satisfy the accuracy requirement of mutual inductor glass 0.5, 0.5s, 0.2, 0.2s, 0.1.◆ 性能特点characteristics磁导率高——可提高互感器使用精度；High permeability—improving the applicable accuracy of the mutual inductor.高饱和磁感应强度——减小仪表保安系数；High saturate induction density—minish the coefficient of the instrument.良好的性价比——重量轻，体积小；Reasonable price—light weight, light measurement良好的温度稳定性——可在 -55--130 ℃ 长时间工作。Excellent stability—with the highest serving temperature from -55 to 130 ℃ for long time. 环形铁芯常用规格Normal toroidal core specifications
