摘要

为解决1~100kA的脉冲大电流校准问题,建立了脉冲大电流校准系统,开展了脉冲大电流校准及溯源技术研究。校准系统由脉冲大电流发生装置、脉冲分流器组、光纤电流传感器、罗氏线圈电流传感器、宽带数据采集系统及测量软件组成;通过该校准系统,可开展脉冲幅度为1~100kA,持续时间为20μs~100ms的脉冲大电流发生/测量系统的校准,开展罗氏线圈传感器、光纤电流传感器等测量器具的校准,校准不确定度优于1%。

Abstract

In order to solve the problem of high pulse current calibration from 1 to 100kA, a high pulse current calibration system was established, and the research on high pulse current calibration and traceability technology were carried out. The calibration system consists of a high current pulse generator, a pulse shunt set, an optical fiber current sensor, a Rogowski coil current sensor, a broadband data acquisition system and a measurement software. The calibration system can be used to calibrate the pulsed high current generation/measurement system with pulse amplitude of 1~100kA and duration of 20μs~100ms. The calibration of Rogowski coil sensor, optical fiber current sensor and other measuring instruments can be carried out, and the calibration uncertainty is better than 1%.
