市政雨水泵站站用系统杂散电流的产生与消除分析

Analysis of Stray Current Generation and Elimination in Municipal Rainwater Pumping Station System

雨水泵站站用系统的不合理接线极易产生杂散电流,使泵站运行存在较大的安全隐患,本文对市政雨水泵站配电系统的常规设计进行简要描述,对站用系统产生杂散电流的原因进行分析,并提出相关的解决措施。同时针对规范中转换开关极数选择的相关要求适用性进行分析,并根据以上结论,对由变压器至低压系统的接线方法提出多种可行方案。

The unreasonable wiring of the rainwater pumping station system is very easy to produce stray current,which makes the operation of the pumping station have great potential safety hazards.This paper briefly describes the conventional design of the power distribution system of the municipal rainwater pumping station,analyses the causes of the stray current generated by the station system,and puts forward relevant solutions.At the same time,the applicability of the standard for selecting the poles of transfer switch is analyzed.Based on the above conclusions,several feasible schemes are proposed for the connection method from transformer to low voltage system.
