摘要
铁路10kV配电所及其馈出线路作为铁路重要的基础设施,需要确保两路可靠电源不间断供电,因此铁路配电所一次主接线设计尤为重要。本文首先分析了单母线分段接线在铁路配电所中应用的优势,指出了其在实际工作中存在的问题。针对酒额铁路配电所电气一次主接线存在的问题,在所用变二路第2段母线上加装电气柜,使其与信号所站馈一回路相连,获得第2条供电回路,解决了一级负荷只由1路可靠电源供电的问题,后期加强设备巡视并做好预防性试验,可提高系统供电可靠性。
As an important infrastructure of the railway,the 10kV railway distribution substation and its feeder lines need to ensure uninterrupted power supply from two reliable power sources,so the design of the primary main wiring of the railway distribution substation is particularly important.Firstly,the paper analyzes the advantages of a single bus sectional connection in a railway distribution substation and then points out its problems existed in the practical work.With regard to the problems existed in primary main wiring of distribution substation of Jiuquan-Ejina Railway,an electrical cabinet is added on section segment of bus bar of the second circuit of auxiliary transformer,and let it be connected to a feeder circuit of a signal post.Then a second power supply circuit is obtained,it is able to solve the problem of with only one reliable power supply circuit.The strengthening of equipment patrol and execution of preventive tests in the later stage are able to improve the reliability of system power supply.
