随着农电事业的大发展,农村电气化建设正在深入进行,我国农村供电面越来越大。但随之而来的不安全用电问题也在农村不断出现,本文试图通过对380/220伏配电线路的重复接地进行粗浅的分析来说明其重要性,供农村电工同志参考。当前农村380/220伏配电系统中绝大多数是单相负荷和三相动力负荷共用一个电源,而农村的自然村又特别分散,也就是供
With the great development of rural power, the electrification of rural areas is being carried out in depth. The power supply area in rural areas in our country is growing. However, the ensuing problems of unsafe electricity consumption are also emerging in rural areas. This article attempts to illustrate the importance of using repeated grounding of 380/220 volt distribution lines to explain the importance of this for the reference of rural electricians. The current rural 380/220 volt distribution system, the vast majority of single-phase load and three-phase power load share a power supply, and rural villages are particularly scattered, that is for
