摘　　要：牵引变电所出口端设置自耦变压器的供电方式,每个取流点都通过自耦变压器电磁关系传递能量,供电距离长、非常适合缺少牵引变电所上级电源的区域,在现场应用中有一定的优势。但在自耦变压器的设置方面存在影响设备安全运行的问题、在故障点测距配合方面存在影响因素较多且不准确的问题。针对现场实际,讨论了自耦变压器等高压设备的设置原则。The AT feeding of setting auto-transformer in exit passes of traction substation energy from electromagnetism,power supply distance long,well adapted for traction substation of lack power,on the spot application have certain advantage.But it exists influence equipment safety circulate of problem on auto-transformer setting and not accurate problem of fault location.Aiming at the actual issues,the principle of auto-transformer etc.high-tension equipment is determined for its settings.
