1、摘要随着社会经济迅速发展，交通运输方式越来越先进，人们对于运输方式的选择也越来越广泛。汽车客运，传统客运的主要方式之一，一直深受人们的青睐。汽车客运站，作为客运与旅客之间的桥梁,如今它不仅被要求外观审美上的舒适，而且在客运服务系统上要追求完美至善。如此而言，汽车客运站除外形的建筑设计外，电气设计也起着至关重要的作用。设计以某汽车客运站的供配电系统为课题，阐述了客运站的发展现状和研究价值；利用需要系数法对客运站负荷进行负荷计算，利用标么值法对系统高低压侧发生短路故障进行了短路电流计算；根据负荷容量选择合适的变压器并确定主接线方案；根据短路计算电流选择断路器、隔离开关、负荷开关、互
2、感器、导线等一次设备并校验;根据原始资料及计算数据，对0.4kV低压侧进行低压配电设计；根据工程实况，对该系统进行防雷接地保护设计，设计保证了客运站供配电及照明系统安全可靠，满足实际运行要求，使汽车客运站电气设计达到安全、可靠、经济、合理的要求。关键字：汽车客运站；数据计算；设备选择；低压配电；防雷接地IABSTRACTWiththerapiddevelopmentofsocialeconomy,meansoftransportationmoreandmoreadvanced,people'schoiceforthemodeoftransportationismoreandmo
