The invention discloses an overhead ground wire ice melting device and method based on a Scott transformer, and the device comprises the Scott transformer, a compensation element, a matching element, a circuit breaker and a measurement and control unit, and can be integrated on a mobile carrier to achieve the mobile deployment. The Scott transformer serves as the core and is matched with the compensation element to adjust the impedance of the ice melting loop, the matching element can enable a single-phase load to be equivalent to a two-phase symmetrical load, and the measurement and control unit and the circuit breaker achieve monitoring, regulation and control and protection of the device. The invention also provides a two-phase ice melting method and a single-phase ice melting method, which are respectively adapted to overhead ground wire ice melting scenes of double-loop different towers and double-loop same tower / single loop, and the Scott transformer converts a three-phase power supply into an adapted two-phase power supply to output ice melting current by constructing a symmetrical load or impedance matching. The problems that three-phase unbalanced current is generated when conventional alternating-current ice melting is applied to the overhead ground wire, and a direct-current ice melting device is complex and poor in maneuverability are solved.
