35 kV配电化线路设计的改善

The Improving on Design of 35 kV Distributional Power Line

35 kV配电化线路,由于其投资少,建设快的特点,在20世纪90年代偏远小负荷地域开始建设,之后随着地方经济的发展,负荷上升,又被常规35 kV线路取代。但目前,一些偏远边境地区,出现用电负荷小,供电距离长,负荷性质十分重要的用户,10 kV线路不能满足这些地区电能质量要求,35 kV配电化被提上建设日程。结合近几年设计的工程,分析原有35 kV配电化线路运行中出现的问题,研究改善35 kV配电化线路设计,旨在提高此种线路安全稳定运行,加快边境地区的供电,节约投资,减少占地,提高经济效益。

Due to its low investment and fast construction,35 kV distribution lines began to be constructed in remote and small load areas in the 1990s.Later,with the development of the local economy,the load increased and they were replaced by conventional 35 kV lines.But at present,in some remote border areas,there are users with small power load,long power supply distance,and very important load nature.10 kV lines cannot meet the power quality requirements of these areas,and 35 kV power distribution has been put on the construction schedule.Based on the projects designed in recent years,this paper analyzes the problems that occurred in the operation of the original 35 kV distribution line,and studies and improves the design of the 35 kV distribution line,aiming to improve the safe and stable operation of this line,speed up the power supply in border areas,and save investment,Reduce land occupation and improve economic efficiency.
