摘　　要：根据轨道交通以往建设经验,8B列车采用DC 750 V电压等级供电较为罕见。本文基于北京地铁13A线改造工程,考虑既有线改造外部制约因素较多,从降低改造风险、实现A/B线互联互通及资源共享、节省投资等角度对北京地铁13A线供电方案进行分析,首选与既有13号线相同的DC 750 V供电制式,并在常规变电所主接线方案基础上增加了3#整流机组。该三机组接线方案提高了变电所的供电可靠性,避免了实际运营中出现变电所解列的工况,是改造工程的一种新的探索,具有合理性和可实施性,为轨道交通线路改造供电制式的选择提供借鉴。According to the past construction experience of urban rail transit,it is rare that 8B train adopts DC 750 V voltage level power supply.Regarding to the reconstruction of Line 13 of Beijing Metro,and with considering that there are many external constraints for reconstruction of the existing line,by analyzing the power supply scheme for Line 13 of Beijing Metro in terms of reduction of reconstruction risk,realizing the interconnection of lines of A/B and resource sharing,saving investment,DC 750 V power supply system,identical to that of line 13,and the third rectifier unit is supplemented to the main wiring scheme for the traditional substation.The wiring scheme of the three rectifier units that is able to improve the power supply reliability of the substation,avoid the outage of substation during actual operation.It is rational,feasible and is able to provide reference for selection of power supply system for reconstruction of existing urban rail transit.
