Research on the calibration system of flexible DC current sensors based on the superconducting equal ampere-turns coil

直流大电流测量设备的准确性对企业产品质量、能耗控制等诸多方面有着重要影响。由于对现有直流大电流测量设备开展计量校准工作时存在一些困难,本文提出采用超导等安匝线圈代替传统等安匝线圈制作校准系统,对用于测量大电流的柔性直流电流传感器进行计量校准,以实现降低系统中标准直流大电流源技术指标要求的目标。

The accuracy of DC high current measuring equipments has an important influence on the quality of products,energy consumption control and so on.Because there are some difficulties in caribrating DC high current measuring equipments,this paper proposes to use the superconducting equal ampere-turns coil instead of the traditional equal ampere-turns coil to make the caribration system.The system will be used to calibrate flexible DC current sensors for measuring high current,and this technology can reduce the technical index requirements of the standard DC current source in the system.
