摘要: 提出了双光路光学电流传感器检测方法及其数据处理方法，即激光输出功率保持不变时，可采用双光路结构和反正切函数处理方法求出待测脉冲大电流。采用双光路光学电流传感器和罗果夫斯基线圈对比测量了充电电压为18 kV、电容为31.8 F的电炮的短路电流，两种测试方法的实验结果取得了较好的一致性,证明了双光路光学电流传感器的有效性。

Abstract: Measuring technology and data processing method of two-path optical current sensor were proposed. High pulse current could be measured by two-path configuration and arc-tangential function processing method with the constant output power of laser. The electric guns short current was contrastively measured by two-path optical current sensor and Rogowski coil at 18 kV voltage, 31.8 F capacity. The experimental result of optical current sensor agreed well with that of Rogowski coil. It proves that two-path optical current sensor can be used to measure high pulse current effectively.
