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
