The utility model provides a direct current ice melting device. The device comprises a thyristor rectifier valve, an alternating current filter, a reactor, an alternating current busbar and a control and protection system. The thyristor rectifier valve is connected with the alternating current busbar through the reactor. The alternating current filter is connected with the alternating current busbar. The alternating current busbar is connected with a low voltage side winding of a substation three winding transformer. The control and protection system controls the switching of the alternating current filter and the work state of the thyristor rectifier valve. According to the direct current ice melting device provided by the utility model, the device has a direct current ice melting function; the economical efficiency and the utilization rate of the whole device are improved; and the cost is reduced.
