The invention discloses a frame leakage current discharging device of a rail transit power supply system, and belongs to the technical field of rail power supply. The system comprises a frame monitoring system used for detecting frame leakage current flowing through a frame, and a frame leakage current discharge module which is connected between a negative return rail and the ground, receives a frame leakage current detection value from a frame monitoring system, and discharges the frame leakage current to the negative return rail when the frame leakage current value is greater than a specified value. According to the invention, small frame leakage current can be drained to the negative electrode, and stray current is prevented from flowing into the ground.

    本发明公开了一种轨道交通供电系统框架泄漏电流排出装置,属于轨道供电技术领域。本发明包括框架监控系统,用于对流过框架的框架泄漏电流进行检测,还包括:框架泄漏电流排出模块,连接在负极回流轨与大地之间,接收来自框架监控系统的框架泄漏电流检测值,当框架泄漏电流值大于指定值时,将框架泄漏电流排流到负极回流轨。本发明能够使较小的框架泄漏电流排流到负极,避免杂散电流流入地下。
