Direct-current deicing output electric switching device

The invention provides a direct-current deicing output electric switching device. The direct-current deicing output electric switching device is composed of an A-phase switching device body (1), an A-phase electric control system (2), an A-phase block system (3), a B-phase switching body (4), a B-phase electric control system (5), a B-phase block system (6), a C-phase switching device body (7), a C-phase electric control system (8) and a C-phase block system (9), wherein the output end of the A-phase electric control system (2) and the output end of the A-phase block system (3) are connected with the input end of the A-phase switching device body (1), the output end of the B-phase electric control system (5) and the output end of the B-phase block system (6) are connected with the input end of the B-phase switching device body (4), and the output end of the C-phase electric control system (8) and the output end of the C-phase block system (9) are connected with the input end of the C-phase switching device body (7). The device has the advantages of being free of hand-operated wiring, high in efficiency, capable of switching among six deicing modes, simple, convenient to use, short circuit resistant, safe and reliable.
