The invention provides a direct current thawing device. The direct current thawing device comprises an SCR (silicon controlled rectifier) rectification valve, an alternating current filter, an electric reactor, an alternating current conflux bus and a control and protection system, wherein the SCR rectification valve is connected with the alternating current conflux bus through the electric reactor, the alternating current filter is connected with the alternating current conflux bus, the alternating current conflux bus is connected with a low voltage side winding of a three winding transformer of a transformer substation, and the control and protection system controls switching of the alternating current filter and work states of the SCR rectification valve. The direct current thawing device achieves a direct current thawing function, improves overall economical efficiency and usage rate, and reduces cost.
