Exterior difference between oil immersion transformers and dry transformers

What is the appearance of oil immersion transformers and dry transformers? Below, Xiaobian will introduce you, the small partners who are interested in, take a look at it.

Exterior difference between oil immersion transformer and dry transformer 

The obvious difference between the oil immersion transformer and the dry transformer is to have "oil", but since the oil is liquid, there is fluidity, the oil immersion transformer must be an organic chemical case, the inside of the outer casing is a transformer oil, wash in the oil. The electromagnetic coil of the substrate is not seen from the outside; the dry transformer has no oil, it does not have a shell, and it is possible to see the electromagnetic coil of the substation; there is a characteristic is oil immersion There is a car oil pillow on the transformer, and the transformer oil is stored inside, but the new oil immersion transformer is also manufactured by transformer in the pillow;

In order to better cool the heat, the oil immersion transformer is convenient to better able to better improve the fluidity heat dissipation of the internal transformer oil, and the heat pipe is designed in the external solution, just like a heat pipe radiator. And the dry transformer does not have this heat pipe heat, heat dissipation by the centrifugal fan under the electromagnetic coil, the centrifugal fan is a bit like a household central air conditioner;

Immersion transformers are generally installed in separate transformer rooms or outdoors due to fire safety, while dry transformers are not suspected to be installed in the room, in general, mounting in high and low pressure distribution room, and high and low pressure The power cabinet is connected side by side.
