摘要
在我国,20kV电压等级曾经出现过很长一段时间,后来被35kV所替代;随着电网发展和负荷密度不断提高,20kV作为配电电压代替10kV再次受到关注。本文对20kV配电电压等级的历史沿革、应用现状进行综述,同时从建设运行和用户两个角度指出了20kV配电的优势所在,并对20kV电网的发展提出部分建议。
In our country,20kV voltage level had existed for a long time,but later was replaced by 35kV. With the development of the power grid and the continuous improvement of the load density,20kV voltage level for distribution instead of 10kV is being another cause for concern. In this paper,the history and applications of 20kV are overviewed. At the same time,the advantages of 20kV from the views both in the operation and the users are pointed out,and some proposals which in terms of 20kV power grid development are raised.
