The invention discloses an automatic lifting energy-saving moisture-proof distribution cabinet, including a lower house, Upper case, drying head, humidity sensors and PLC controllers, at both side ofthat lower house, the upper housing is movably clamped by a first electric telescopic rod, an upper end of that low housing is connected with a drying head movably assembled with the through hole through a second electric telescopic push rod. The drying head is provided with an air inlet and an exhaust structure, the air flow of the drying head enters the lower housing through the first air inlethole and is discharged through the drying head when the drying head is raised, the first air inlet hole is blocked when the drying head is lowered, and the air flow is sucked through the air inlet structure of the drying head and is discharged from the exhaust structure. As that humidity sensor sense a higher humidity in the low housing. The second electric telescopic push rod drives the drying head down, the first air inlet hole is blocked, the air flow enters through the upper end of the second air inlet hole and dries under the action of the desiccant when the fan is driven, enters the lower shell and is discharged through the exhaust hole, so that the internal drying can be efficiently ensured on the basis of ensuring heat dissipation.
