随着铁路运输事业的发展,电气化铁路规模与日俱增,牵引变电所单直流电源系统越来越不适应生产和管理的需要,给检修和事故抢修带来许多不便。鉴于一些既有所直流电源改造还存在一定的困难,以及直流系统的故障机率较低的特点,建议在单直流电源系统的变电所采用移动式抢修检修备用直流电源。
With the development of railway transportation and the increasing scale of electrified railways, the single DC power supply system in traction substation is becoming increasingly unsuited to the needs of production and management, which brings many inconveniences to maintenance and accident repairs. In view of some existing DC power transformation there are still some difficulties, as well as the lower the probability of failure of the DC system, it is recommended to use a mobile power overhaul in the single DC power system substation backup DC power supply.
