Cooling and auxiliary equipment
Generally, it is ONAF/ONAN type, when ONAF, it runs with full load; When ONAN, the load is running 67% of the full load.
The radiator is flake type, the seam between the flakes is welded.
The open and close of the fan motor are controlled by oil temperature and olad, The controlling apparatus is attached on the transformer.
The conservator is in capsule type. There is oil-resisance, high temperature proof, air-sealed capsule to insulate the oil and the outside air, so that oil is outside the capsule and air is inside the capsule. In order to improve the stability of the transformer, the air room of the capsule closes the outside air through silicongel breaher.
