牵引变电所接地引下线的选择

Selection of Traction Substation Earthing Down Lead

针对越来越多的牵引变电所采用高电压等级供电,牵引变电所进线侧的系统短路容量和短路电流越来越大的工程实际情况,对牵引变电所接地引下线的选择进行了讨论。

With respect of the actual situation of more greater system short circuit capacitance and short circuit current at incoming line side of the traction substation along with more and more application of high voltage level power supply in traction substation, the paper discusses the selection of the traction substation earthing down lead.
