The invention discloses a direct current deicing device for a 10KV rural power grid distribution line. The direct current deicing device consists of two parts, namely a plurality of movable 380V alternating current power supplies and a direct current constant current heating power supply. The direct current output end of the direct current constant current heating power supply is connected to endpoints of two phase lines of a transmission line to be deiced through a cable. 380V alternating current power is rectified and filtered to obtain high-voltage direct current, the high-voltage direct current is transmitted to inverter circuits consisting of field effect transistors after being rectified and filtered, and is converted into high-frequency alternating current with an adjustable pulse width through main circuit units, and the high-frequency alternating current is stepped down through high-frequency transformers taking amorphous soft magnetic materials as cores, and then is rectified and converted into direct current heating power required by deicing in Schottky diodes. A control signal output by a control unit can quickly respond to the output of the main circuit units, and make a quick protection response to a failure. Ice and snow on a conducting wire are thawed by utilizing heat produced by the direct current resistance of the conducting wire when heavy current flows through the conducting wire, so that the direct current deicing of an iced 10KV rural power grid distribution line is realized.
