摘　　要：为了提高铁路枢纽地区、短程市域铁路牵引变电所主接线的可靠性,最大限度地避免牵引变电所严重故障造成的全所退出运行情况,以全户内布置的110 kV分支接线牵引变电所为例,本文从可靠性、灵活性、经济性3个方面研究了牵引变电所高压侧与低压侧多条进线、多台牵引变压器的主接线方案,总结了适用于铁路系统的牵引变电所多条进线、多台牵引变压器的最优主接线方案。外电可靠性较高时,高压侧主接线推荐采用两进线三主变分支接线方案;外电可靠性较低时,高压侧主接线推荐采用三进线三主变接线方案,低压侧主接线推荐采用第3台主变27.5 kV侧进线侧独立设置的主接线方案。In order to improve the reliability of the main wiring of railway traction substations in railway hub areas and shortdistance urban areas,and to avoid the withdrawal of the whole traction substations caused by serious faults to the maximum extent,this paper takes the 110 kV branch wiring traction substations arranged inside the house as an example.The main wiring scheme of multiple power supply lines and multiple traction transformers on the high and low voltage sides of traction substation is studied from the aspects of reliability,flexibility and economy.The optimal main wiring scheme suitable for multiple power supply lines and multiple traction transformers in traction substation of railway system is summarized.In the case of high reliability of external power,it is recommended to adopt the main wiring scheme of two power supply lines and three main transformer branches on the high voltage side.In the case of low reliability of external power,it is recommended that the high-voltage side main wiring scheme should be three power supply lines and three main transformers,and the low-voltage side main wiring scheme should be independently set at the 27.5 kV side inlet line of the third main transformer.
