| 摘 要： | 在城市轨道交通直流牵引供电回流系统中,钢轨电位与杂散电流为回流系统中相互关联的参数,而钢轨电位限制装置(OVPD)与排流柜各自独立工作,互不协调。为进一步限制回流系统中的钢轨电位与杂散电流,需对OVPD与排流柜进行综合优化。分析了多区间情况下OVPD与排流柜的投入与退出对钢轨电位及杂散电流的影响,并提出了OVPD与排流柜综合优化方案。

| Abstract: | In the reflux system of traction power supply,rail potential and stray current are interrelated parameters of reflux system,but OVPD and drainage cabinet work independently without any coordination.To further limit the rail potential and stray current,it is necessary to optimize OVPD and drainage cabinet comprehensively.In this paper,the influences on rail potential and stray current by the working conduction of OVPD and drainage cabinet at multiple intervals are analyzed,comprehensive optimization on OVPD and drainage cabinet is proposed. |

| Keywords: | rail potential stray current OVPD (over-voltage protection device) drainage cabinet |
