Background
The transformer is an important device of a power system, the reliable operation of the transformer has great significance to the safe and economic operation of the power system, and once a fault occurs, serious economic loss is often caused, and even the stability of the operation of a power grid is damaged. The traditional dry-type transformer for the thermal power plant often causes damage to internal equipment of the dry-type transformer due to a complex environment of the thermal power plant in the use process, and the main reason is that the conventional dry-type transformer is not matched with the running environment of the whole machine from a heat dissipation system, so that the service life of the dry-type transformer is greatly reduced. More specifically, the problem that the cooling efficiency cannot reach the verification efficiency due to the fact that a self-cooling system of a transformer is difficult to maintain under severe operating conditions such as serious dust emission in a thermal power plant is solved. In view of the above problems, a corresponding solution is still lacking.
