摘要
通过对北京地铁1、2号线原供电系统设备现状和供电方案研究,提出地铁变电所在改造过程中,交流10kV供电网络、直流750V牵引供电系统、低压0.4kV配电系统的过渡方案和应急预案;指出地铁在不停运的条件下,供电系统改造的难点和过渡方案存在的风险性;最后给出了北京地铁1、2号线供电系统改造优化研究方案。
The paper proposes a transitional scheme and an emergency scheme for the AC 10 kV supply net, the DC 750 V traction supply system and the 0.4 kV low-voltage system in the renovation of the transformer substations through the investigation into the old supply scheme and the state of the equipment of the existing supply system. It points out the difficulties in the renovation of the power supply system and the risks of the transitional scheme under the condition of operation without interruption, Finally, it puts forward an optimal scheme for the renovation of the power supply system on line 1 and line 2 of Beijing Subway.
