The difference between
Dry Type Transformer and
Oil Immersed Transformer is
[Xuzhou transformer manufacturer] different appearance, packaging form
Dry Type Transformers can see the core and coil directly, while oil immersed transformers can only see the transformer shell.
[Xuzhou transformer manufacturer] lead form is different
Dry-type transformers mostly use silicone rubber casings, while
Oil-Immersed Transformers mostly use magnetic casings.
[Xuzhou transformer manufacturer] capacity and voltage are different
Dry type transformer is generally suitable for distribution, the capacity is mostly below 1600 kVA, the voltage is below ten kV, there are also individual 35 kV voltage grade, while the oil-
Immersed Transformer can from small to large to do the whole capacity, the voltage grade page does all the voltage, our country is under construction of UHV 1000 kV experiment, The line must be oil-immersed transformer.
Insulation and heat dissipation are not the same
The transformer is generally insulated by resin, cooled by natural air, and cooled by fan for large capacity. The oil-immersed transformer is insulated by the insulating oil, and the heat generated by the coil is brought to the radiator of the transformer for heat dissipation by the circulation of the insulating oil in the transformer.
[Xuzhou transformer manufacturer] different places of application
Dry type transformer is mostly used in the need for fire prevention, explosion-proof places, generally large buildings, high-rise buildings should be used, and oil-immersed transformer, because of the possibility of oil spray or leakage after the accident, resulting in fire, mostly used in the outdoor, and there is a site to dig the accident oil pool.
[Xuzhou transformer manufacturer] different load bearing capacity
Generally, dry-type transformers should operate at rated capacity, while oil-immersed transformers have better overload capacity.
[Xuzhou transformer manufacturer] the cost is not the same
For the same capacity transformer, the purchase price of the secretary transformer is much higher than the price of the oil-immersed transformer. The dry type transformer model generally begins with Sc(epoxy resin casting encapsulation type), SCR(non-epoxy resin casting solid insulation encapsulation type), SG(open type).
