The cooling mode of dry type transformer is explained in detail

Dry transformer is a kind of important equipment widely used in power system, its main feature is to separate the iron core and winding, cooling by air or special insulating oil. Compared with the traditional oil-immersed transformer, dry transformer has the advantages of small size, light weight and easy maintenance. However, due to the particularity of its heat dissipation mode, the dry transformer needs to take certain cooling measures during operation to ensure its normal operation.

Natural air cooling: The natural air cooling of dry transformers is a simple cooling method. Vents are set up around the transformer to cool the transformer using the air flow in the natural environment. This method is suitable for occasions with low ambient temperature and small load. However, when the ambient temperature is high or the load is large, natural air cooling may not meet the cooling requirements, and other cooling methods need to be taken.

2. Forced air cooling: In order to improve the heat dissipation effect of dry transformers, forced air cooling can be used. The external air is introduced into the transformer through the fan, forming a airflow cycle and taking away the heat generated by the transformer. Forced air cooling can improve the cooling effect, but it will increase energy consumption and maintenance costs.

In short, there are a variety of cooling methods for dry transformers, and the appropriate cooling method needs to be selected according to the actual working conditions and environmental conditions. At the same time, in order to ensure the normal operation of the dry transformer, it is also necessary to check and maintain the cooling system regularly to ensure that the cooling effect is good.
