摘要
电磁感应线圈 (茹可夫线圈 )可用于大电流试验回路和断路器的信号检测。研究了电磁感应线圈在信号采集电路中 ,积分电路的时间常数大小对被测电流在积分电路上的电压误差的影响 ,并根据所要求的电压误差给出了可选用的时间常数。
The electromagnetic induction coil may be used for signal detecting of high capacity current test circuit and circuit breaker. For electromagnetic induction coil in signal sampling circuit, the time constant of integrating circuit how to affect voltage deviation of current to be measured in integrating circuit was studied, the optional time constant for required voltage deviation was also given.
