摘要 本文研究了电力系统中用于暂态大电流测量的Rogowski线圈电流传感器传感头的频率特性,分析了不同终端电阻值的选取对线圈测量带宽的影响,在此基础上设计一种将无源外积分、有源外积分相结合的复合式积分信号处理电路,论述了复合式外积分器能够在保证传感器具有合适灵敏度的前提下,将传感器的工作频带由低频提高到线圈的谐振频率附近;最后,文中以自制的灵敏度为2mV/A的复合式外积分罗氏线圈为例,给出参数设计过程和实验波形,对50Hz电网电流与250A/μs上升沿的脉冲电流的准确检测验证了该信号处理电路较其他外积分电路可工作在更宽的测量范围。 In this paper, high frequency behavior for a Rogowski coil is analyzed, Considering the model of the coil frequency response, a novel compound integration circuit is described in this paper which is consisted of passive RC integration and active RC integration. This compound integrator improvements the measurement upper frequency limit of transducer across coil natural frequency. A coil of 100 wound number is constructed using compound integrator which is designed under band-width of 1Hz- 2. 8MHz and sensitivity of 2mV/A. Experiment waveforms verify the transducer operates with both a grid current measurement and a transient current of 250A/μs di/dt.
