提高城市轨道交通车站配电变压器负荷率措施

摘要

以已运营城市轨道交通车站配电变压器负荷率普遍偏低的现象为出发点，通过对城市轨道交通典型车站动力照明负荷构成、负荷分级、运行方式等的特征分析，并结合变压器运行特性，提出根据城市轨道交通动力照明负荷特性合理确定变压器容量，以及充分利用变压器过负荷能力，从而有效提高城市轨道交通车站配电变压器负荷率的措施。%　　In view of the low distribution transformer load rate of urban rail transit stations in service, measures to effectively improve the load rate through determining the transformer capacity in accordance with the power&lighting load characteristics and making full use of the capability of overload of transformers are put forward based on analysis of the load composition, load classification and operation mode of power&lighting load of typical stations in combination with the operation characteristics of transformers.
