Abstract:

该文介绍了一种在线校验用标准电流互感器的设计。该电流互感器基于电磁感应原理,利用双铁芯工作,并引入了无源补偿,具有开合式结构,能够在线安装,抗干扰能力强,其输出为模拟小信号,能直接被采集系统采集。实验结果表明,其精度优于0.05级,并且在开合50次后,仍能满足0.05级的标准要求。
This paper introduces the design of a standard current transformer for on-line calibration. The current transformer based on the electromagnetic induction theory works with dual cores and has the passive compensation circuit. It not only can be installed on line due to the open-close structure, but also possesses a strong anti-jam capability. The output of the current transformer is small analog signal which can be picked up directly by acquisition system. The testing results show that the accuracy class of the current transformer is better than 0.05 and it still can meet the standard when opened and closed 50 times.
