本文在对牵引供电系统现采用自动重合闸方式分析基础上,提出新的牵引供电系统自动重合闸方式,即采用分区所“一次”重合闸与牵引变电所“检压”重合闸配合的方式,可以有效的减少接触网发生永久性故障时对一次设备特别是牵引变压器、断路器影响,从而延长一次设备的使用期限。
Based on the analysis of the auto-reclosure method of the traction power supply system, a new auto-reclosure method of traction power supply system is proposed in this paper, that is to say, the “one time” reclosure and the traction substation Gate with the way, can effectively reduce the catenary network permanent failure of a device, especially the traction transformer, the impact of circuit breakers, thereby extending the life of a device.
