Outdoor dehumidification electrical cabinet for transformer substation

The invention belongs to the technical field of power equipment, and particularly relates to a transformer substation outdoor dehumidification electrical cabinet which comprises a cabinet body, a cabinet door, a mounting plate and a dehumidification component. Water absorption cotton is arranged on the top faces, the back faces and the two side faces of the cabinet door and the cabinet body, then condensation generated on the inner wall of the cabinet body is absorbed, a controller controls a first motor to rotate forwards and backwards, then a belt wheel and a synchronous belt drive a rotating shaft to rotate, then the rotating shaft drives blades to rotate, all the blades rotate synchronously, and therefore the condensation effect is improved. The water-absorbing cotton is rotated to the outer side or the inner side of the cabinet body, the wet water-absorbing cotton is aired or condensation on the inner side of the cabinet body is absorbed, the water-absorbing cotton can be reused, condensation is prevente
