摘 要：介紹了泵站電力系統(tǒng)的二次電壓回路，共性上二次電壓的回路結(jié)構(gòu)都可以分解為源頭、母線、分支和隔離保護(hù)設(shè)備，并給出了造成二次電壓回路個(gè)性的原因。通過對(duì)仙人大港泵站雙向運(yùn)行泵站中的二次電壓回路的分析，檢查出電壓互感器V-V 連接方式接地線接錯(cuò)的問題，排除了熔斷高壓熔絲的隱患。
關(guān)鍵詞：二次電壓回路；故障排除；雙向運(yùn)行泵站

Abstract: Introduction was made to the secondary voltage circuit of power system in the pumping station. The secondary voltage circuit structure from the corner of generality could be divided into source, bus bar, branch and insulation blocking equipment, and the cause of secondary voltage circuitindividuality was given. After the analysis of the secondary voltage circuit of two-way running pump station in Xiaren grand port pump station, the voltage transformer was examined and it was found that the V-Vconnection with grounding wire was wrong, which eliminates the hidden danger of the high pressure fuse.
Key words: secondary voltage circuit; troubleshooting; two-way running pump station
