摘要
随着国内某些地区配电网用电负荷的剧增和可用土地面积的约束,以及其他一些技术因素和客观原因,20kV电压等级的推广应用逐步提到了相应的议程。分析了当前国内外20 kV的应用现状,阐述了20 kV电压等级的优缺点,从实用的角度对20 kV这一电压等级的经济性进行了详细的分析。
With the increasing of the power load in certain distribution network and the restricting of the usable glebe, the voltage level of 20kV is brought forward step by step. The application and the merit are expounded in this paper, and the economical advantages of 20kV distribution system are analyzed in detail.
