The invention provides a device and a system for reducing running rail current, the device comprises an input end, an output end and a filtering unit, the filtering unit receives a voltage signal and/or a current signal of a running rail at the input end and releases a harmonic compensation current according to the voltage signal and/or the current signal, and the harmonic compensation current is used for reducing the running rail current. The harmonic compensation current enters the walking rail through the output end; wherein the harmonic compensation current is used for eliminating backflow harmonic components in the running rail. The device and the system using the device can filter the harmonic component in the backflow of the running rail so as to avoid the leakage of the flow.

    本发明提供了一种减少走行轨迷流的装置及系统,所述装置包括输入端、输出端和滤波单元,所述滤波单元在所述输入端接收走行轨的电压信号和/或电流信号,并根据所述电压信号和/或所述电流信号释放谐波补偿电流,所述谐波补偿电流通过所述输出端进入所述走行轨;其中,所述谐波补偿电流用于消除所述走行轨中的回流谐波成分。该装置及利用该装置的系统能够对走行轨回流中的谐波成分进行滤波,以避免迷流外泄。
