摘　　要：大型及以上铁路客站的供电分区划分方案决定客站内电分段数量,也决定列车受电弓通过电分段产生的电弧烧蚀接触线、承力索或吊弦的概率。结合铁路枢纽典型的牵引供电方案,从工程方面对大型及以上铁路客站牵引供电分束分段进行深入研究,从减少电分段数量、消解电分段两端电压差和环流等方面对传统设计的大型及以上铁路客站供电分区划分、分束分段设置方案进行优化,提出5个优化方案,既减少了列车受电弓通过电分段产生的电弧影响,又确保了站线故障后不会扩大故障影响范围,为新建大型及以上客站的牵引供电分区设计、既有大型及以上客站供电分区优化提升提供参考。The scheme for dvision of switching sections for lage and above passenger station determine the numberof the electrical separations inside the passenger station,as wel as the probability of arc erosion of contat wires,messenger wires and dropp ers generated by the pantograph on top of train passing through the eledtrical sep arations.Cornbining with the typical traction power supply schemes of railway hubs,profound reseach is made for the switching.groups and switching sections for the large and ab ow e railway passenger station in terrns of engineering.The division ofswitching sections and the setting and enlargernent of sw itching groups for the large and above passenger station withtradtional design are optimized in terms of reduction of number of electrical sep ar ations,elimination of voltagedifference betw een both ends of the electrical sep aration as well as the loop current.5 schemes for the optimizationbeing put forwand are able to minimize the influence of electric arcing caused by the pantograph passing through theeledtrical sep aration and ensure that the scope of fault will not be exp anded when the fault is occurred in the station line,providing refarence for the design of eledrical separation for new large and above passenger stations,and theoptimization and improv ement of elecrical separation for existing large and abov e passenger stations.
