随着上海铁路局全面电气化时代的来临,铁路电气化动力心脏牵引变电所的安全运行成为关键。从投入、产出的安全性、经济性角度出发,提出了牵引所操作后备直流电源蓄电池容量的选择计算方法。该计算适用于设计、设备选型、后期维护等各个时期的容量计算和校核。 With the advent of the full electrification era of Shanghai Railway Bureau, the safe operation of the electrified heart traction substation of railway electrification becomes the key. From the point of view of input and output safety and economy, a method of selecting and calculating the battery capacity of backup DC power source operated by traction is proposed. The calculation applies to the design, equipment selection, maintenance and other stages of capacity calculation and check.
