Maintenance-free moisture absorption device for transformer

Abstract

The invention discloses a maintenance-free moisture absorption device for a transformer, and relates to the technical field of transformers, the maintenance-free moisture absorption device comprises two fixed metal plates, the bottom surfaces of the two fixed metal plates are fixedly connected with drying cylinders, the lower sides of the inner walls of the two drying cylinders are fixedly connected with moisture absorption cylinders, and the surfaces of the two moisture absorption cylinders are provided with a plurality of ventilation openings; the multiple ventilation openings are arc openings, and the upper sides of the inner walls of the two drying cylinders are fixedly connected with conveying vertical pipes. A drying material in the device has the effect of being convenient to replace, the problem that continuous drying of the transformer cannot be guaranteed due to the fact that the drying material in the device is moist or the drying material is aged for a long time and loses the moisture absorption function is solved, the device adopts a left-right mutual exchange drying mode, it is guaranteed that dry air in the device is smooth and not blocked, and the drying efficiency is improved. The device has the function of discharging condensed water generated by heating and drying, and the problem of electric energy loss caused by re-evaporation of the condensed water by the device is avoided.
