The invention provides an overhead line system power supply device for heat preservation of a motor train unit and a power supply method thereof. The overhead line system power supply device for heat preservation of the motor train unit comprises an industrial power source and a voltage transformation device (3), and the industrial power source is connected with the input end of the voltage transformation device (3); and the voltage transformation device (3) can convert the voltage of the industrial power supply into 25kV output voltage and supply power to the arrival-departure line contact net (9) or the parking line contact net (11). According to the overhead line power supply device for heat preservation of the motor train unit, a common industrial power supply is adopted nearby, the voltage of the common industrial power supply is transformed to 25 kV, and the overhead line is connected into an arrival-departure line or parking line overhead line for parking the motor train unit and used for heat preservation of the motor train unit. Independent power supply to the arrival and departure line or parking line contact network is realized, and a special power supply line is prevented from being arranged from an adjacent transformer substation to the station, so that the engineering investment and the operation cost can be greatly saved.

    本发明提供了一种用于动车组保温的接触网供电装置及其供电方法,所述用于动车组保温的接触网供电装置包括工业电源和变压装置(3),该工业电源与变压装置(3)的输入端连接,变压装置(3)能够将该工业电源的电压变为25kV的输出电压并为到发线接触网(9)或存车线接触网(11)供电。该用于动车组保温的接触网供电装置就近采用普通工业电源,将其电压变压至25kV,接入停放动车组的到发线或存车线接触网,用于动车组保温。既实现了向到发线或存车线接触网独立供电,又避免了从相邻变电站到本站设置专用供电线路,可大量节省工程投资和运营成本。
