【摘要】 长大隧道的配电,供电距离长,电压损失大,影响用电设备的正常工作,采用交流电压补偿器不能有效提高其供电距离,只有采用高压进洞才能减少电压损失和电能损失,获得较好的经济性,本文就施工初期的低压进洞及施工中后期的高压进洞方案进行分析和研究,设计了广大铁路祥云隧道高压配电方案,满足了施工设备的用电需求,降低了运行成本。更多还原

【Abstract】 The voltage loss of long distance power supply always affects the normal operation of electrical equipment in the tunnel. AC voltage compensator can not effectively improve its power supply distance. Only by applying the high voltage power supply can reduce the voltage loss and power loss. In this paper, the low voltage power supply at the early stage and the high voltage power supply in the later stage are analyzed; the high voltage power supply programs of Xiangyun tunnel are designed. The construction process shows that the program can meet the electricity demand and reduce the operating cost.更多还原
