摘　　要：本文研究了牵引变电所里备用牵引变压器“热备”功率损耗、功率因数附加费及“冷备”状态转“运行”状态所需投切时间。结果表明,备用牵引变压器采用“冷备”方式经济效益更好。并根据国内电气化铁路运行经验对该项目备用牵引变压器日常维护提出了一些具体做法。This paper studies the"hot standby"power loss of the standby traction transformer,the power factor surcharge,and the switching-on time required for the"cold standby"state to"operation"state of the standby traction transformer in the traction substation.The results show that it is more economical to use the"cold standby"method for standby traction transformers.And according to the domestic electrified railway operation experience,some specific methods are put forward for the daily maintenance of the standby traction transformer of this project.
