Dry type transformer is a commonly used power transformer. It is directly reflected with the atmosphere. It is suitable for relatively dry and clean indoor environment. Generally, there are two cooling methods: air self cooling and air cooling.
Enclosed dry-type transformer: the dry-type transformer is located in the enclosed enclosure and does not directly contact with the atmosphere (due to poor sealing and heat dissipation conditions, it is mainly used for mining and belongs to explosion-proof type).
Pouring type of dry-type transformer: epoxy resin or other resin casting is used as main insulation. It has simple structure and small volume, and is suitable for transformers with small capacity.
Temperature control system of dry type transformer
The safe operation and service life of dry-type transformer largely depends on the safety and reliability of transformer winding insulation.
