摘要
10 kV配电变压器重过载运行不仅会影响社会生产,而且会影响到民众的生活秩序。针对配变重过载问题,首先结合供电企业实现配变互换的必要条件定义了相关参数,并提出了负载率限值以限制互换后配变的负载率;其次提出了配变匹配调换方法的具体步骤以及流程图;最后,选取了某市部分配变证明了该方法的实用效果。
10kV distribution transformer overload will not only affect social production, and will affect people＇s lives. According to the distribution transformer overload problems, firstly, some parameters are defined with necessary condition for interchange of distribution transformer, and load limit is proposed to limit the load rate after exchanging transformer. Then, the specific steps of matching exchange method and flow diagram are presented. Finally, the practical effect of this method is proved by selecting some distribution transformer.
