A subway-oriented power transmission facility comprises a DC transformer, power storage equipment, electric quantity monitoring equipment and a PLC. The DC transformer is connected to the DC side of the power transmission line in parallel; during subway power transmission work, the DC transformer converts 600V electromotive force of a DC side of a power transmission line into 160V electromotive force meeting electromotive force standards of power storage equipment; and after the subway loses power, the 160V electromotive force of the power storage equipment is boosted to achieve 600V electromotive force specification of the DC side of the power transmission line, so that power transmission of the subway when the subway passes through a power-free interval is achieved. And in combination with other structures, the defects that in the prior art, no electromotive force is provided for the subway when the subway passes through the non-electric intervals, so that the suitability of the subway is weakened, and the suitability of passengers is further not facilitated when the subway passes through the non-electric intervals are effectively overcome.

    一种面向地铁的输电设施,包括DC变压器、蓄电设备、电量监控设备以及PLC;所述DC变压器并连于输电线路的DC边;在地铁输电工作时,DC变压器把输电线路DC边的600V电动势转变为满足蓄电设备电动势规范的160V电动势;在地铁失电后,把蓄电设备的160V电动势执行增压,来达成输电线路DC边的600V电动势规范,达成地铁在过无电区间时的输电。结合其它结构有效避免了现有技术中在通过无电区间之际未有电动势给以地铁、使得地铁的适宜性减弱、在通过若干无电区间时进一步不利于乘客适宜性的缺陷。
