用全寿命周期成本法选择地铁变压器

Selection of Transformer Used in Subway by Full Service Life Cyclic Cost Comparison Approach

本文根据地铁负荷的实际情况,通过对在运营的广州地铁一号线中的实际负荷统计,提出应用设备全寿命周期方法选择地铁系统主变压器、牵引变压器和动力变压器,以达到减少地铁变压器安装容量,降低变压器运行损耗,从而节省建设和运营费用的目的。对地铁供电系统的设计和运营具有一定的参考价值。

According the subway real load condition, by investigating the real load Statistic of Guangzhou subway line 1, to table a proposal of the full service life cost comparison approach for selection transformer, traction transformer, power transformer etc. Reduces the capacitance and running wastage of transformer used in subway system, sequentially reach the point of reducing the expenditure of installation and running. There are definite referenced value for design and running of subway power supply system.
