摘要
国内电力行业中运用的配电网等级主要集中为10 kV、35 kV,这在早期社会发展中基本上能满足用户的使用需求。但随着社会城市化建设进程加快,之前所运用的10 kV、35 kV电压等级已经无法与社会经济发展协调,这对配电网电压等级的标准提出了更严格的要求。20 kV电压等级凭借其自身的优势在电网运行中得到了广泛的应用,促进了社会供电系统的持续运行。文章重点分析了20 kV电压等级的运行优势、制约因素及推广方式。
The use of domestic power industry level mainly as a distribution network 10 kV,35 kV,which in early social development can basically meet the needs of the users.But with the accelerated process of urbanization of society,before the use of 10 kV,35 kV voltage level has been unable to coordinate with the social and economic development,which for the standard voltage distribution network made more stringent requirements.20 kV voltage level,with its own advantages the power grid has been extensive operation,and promoting the social power system running.This article focuses on analysis of the 20 kV voltage level of the operational benefits,constraints and popularization way.
