本文对农村配电网存在的问题进行了调查研究,主要是配电室设计容量小,配电台区远离负荷中心,线路架设规划不合理,供电半径过长,导线半径细,表箱、接户线锈蚀、老化严重,变压器三相负荷不平衡,配电出线少,变压器容量配置缺乏灵活性,用户对装设剩余电流末级动作保护装置的重要性认识不足等,本文给出了相关对策。
In this paper, the problems of rural distribution network were investigated, mainly the design capacity of distribution room is small, with the distribution area away from the load center, the unreasonable planning of the erection of the line, the power supply radius is too long, the wire radius is fine, Household corrosion, serious aging, unbalanced three-phase load of the transformer, less distribution outlet, lack of flexibility in the configuration of the transformer capacity, and lack of awareness of the importance of the user in installing the residual current protection device. In this paper, relevant countermeasures are given .
