A thermodynamic de-icing device for transformer equipment includes a housing and a substation, A subset is disposed within the housing, An anti-freezing device is arranged on that house and includes aheating assembly, A shake device and a blow device, A shake device includes a first shock plate, a second shock plate and a shock assembly, Thefirst shock plate and the second shock plate are provided, so that the outer snow falls on the first and second panels, A first vibration plate is driven to slide on the upper side of the housing by the vibration assembly, the second shock plate slides reciprocally on the upper side of the first shock plate, The snow falling on the first shock plate and the second shock plate does not accumulate, and the heating assembly helps melt the snow and furtherassists in clearing the snow, and the first shock plate and the second shock plate can push each other so as to loosen the snow with a thicker thickness, thereby realizing the effect that a single shock plate cannot achieve.
