直供全并联供电方式下并联所设计方案探讨

摘要

By analyzing the normal operating mode, the overhaul operating mode, the fault operating mode and the relay protection needs of the traction power supply system in the different wiring scheme, several main wiring proposals of parallel switching post in TRNF all-parallel supply mode are proposed, and the recommended wiring proposals of the parallel switching post are given under different route standards. Based on those recommended proposals, corresponding relay protection formula is devised.%文章通过分析不同接线方式下牵引供电系统的正常运行、检修运行、故障运行方案及继电保护需求，给出了直供全并联供电方式下并联所的几种主接线方案，单纯并联所、半分段并联所、全分段并联所，得出了在不同线路标准下并联所接线型式的推荐方案。并针对推荐的接线方案提出了相对应的继电保护方案。
