箱式牵引变电所已经成为了有轨电车牵引供电的首选,但是目前箱式牵引存在诸多的问题。本文通过分析现有设备的问题,提出了10k V电源系统优化,箱变整体布置优化,箱变工厂内完成调试,箱变内系统接地优化,微正压的环境控制,全铜排的连接设计,箱柜一体化的结构设计,箱变与环境和谐统一的外观喷绘设计等方案和结构的优化设计,完善了箱式牵引所在轨道交通行业的应用,为其快速健康发展的提供有力保障。 Box-type traction substation has become the tram traction power supply of choice, but the current box-type traction there are many problems. In this paper, we analyzed the problems of existing equipment, proposed the optimization of 10k V power supply system, the overall layout optimization of box change, the debugging of box change in factory, the optimization of grounding in box system, the positive control of micro- , Bin integrated structural design, bin change and environment, a unified design of the appearance of inkjet design and optimization of the structure of the program to improve the box traction where the application of the rail transit industry for its rapid and healthy development to provide a strong guarantee.
