Abstract

The invention relates to the field of transformers, in particular to a power electrical transformer with a self-cooling function. The transformer comprises a transformer outdoor closed protection frame, an adjustable transformer on-load fixing base, a self-adjusting driver, a self-adjusting sliding front door, a plurality of ventilation side doors and a compressed air expansion expansion device, the adjustable transformer on-load fixing base is connected to the rear end of the transformer outdoor closed protection frame in a threaded fit mode, the front end of the adjustable transformer on-load fixing base is attached to the self-adjusting driver, the self-adjusting driver is in meshing transmission with the self-adjusting sliding front door, and the self-adjusting sliding front door is rotationally connected into the transformer outdoor closed protection frame. The transformer has the beneficial effects that when the transformer works and the temperature is high, a closed protection shell is automatically opened for ventilation, and when the transformer does not work and the temperature is normal, the closed protection shell carries out effective closed protection on the transformer located outdoors.
