500kV输电线路不停电跨越电力线施工探讨

Construction Discussion on 500 kV Transmission Line Spanning Power Line Without Power Cut

介绍了江西省送变电建设公司在三峡孝感—汉阳Ⅱ回500kV输电线路工程中,采用迪尼玛承力绳不停电跨越220kV、110kV电力线路施工并获成功的方法,该施工方法与传统的跨越施工方法相比,在技术上和经济上都具有较好的优越性,该方法不仅能较好解决电力线路运行单位提出的跨越施工时线路不停电的问题,而且对跨越高速公路铁路,经济作物等跨越施工也具参考价值。

This paper introduces using DiNiMa catenary to span 220 kV, 110 kV electric power line construction without power cut and gains success in the project of Sanxia Xiaogan-Hanyan 11 circuit 500 kV transmission line. Compared to the traditional span construction method,this span construction method has the advantage in technology and economics. This method can not only solve the problem of line withont power cut when span construction,but also supply reference value to span construction.
