摘　　要：在高压大容量检测系统中,电流测量系统作为重要的组成部分,用于对开关、熔断器等电气设备进行高压大电流试验时的瞬态数据测量,以及开断能力、抗短路能力等关键指标的测试。传统高压大容量检测系统中电流测量所使用的电流分流器、电磁式电流互感器、罗氏线圈、霍尔传感器等有着各自的应用局限性,对测量系统的精确度、抗干扰、稳定性等对测量结果有直接影响。分析了当前高压大容量测试系统中不同类型电流采集系统的优缺点,对应用于当前系统中的光纤电流互感器的研究过程进行了简要概括,并通过在系统中实际引入光纤电流互感器产品与传统测量方式进行了比较,验证了产品应用于高压大容量检测系统的可行性。In high-voltage high-capacity detection systems,the current measurement system is an important component,used for transient data measurement during high-voltage high-current tests on electrical equipment such as switches and fuses,as well as testing key indicators such as breaking capacity and short-circuit resistance.Because the current shunt,electromagnetic current transformer,roche coil and hall sensor used in the traditional high-voltage and high-capacity test system have their own application limitations,they have a direct impact on the accuracy,anti-interference and stability of the measurement system on the measurement results.This paper analyzes the advantages and disadvantages of different types of current acquisition systems in the current high voltage and large capacity testing system,and briefly summarizes the research process of optical fiber current transformer used in the current system,and verifies the feasibility of the product applied to the high voltage and large capacity testing system by comparing the actual introduction of optical fiber current transformer products in the system with the traditional measurement methods.
