difference between dry transformer and oil transformer
The dry type transformer and the oil type transformer are the transformer types we are more familiar with, and we all need to use them in production and life. We can see many problems in the comparison between dry type and oil type transformers. In this way, we can strengthen our use and care, and we must continue to improve its maintenance. For use, operation and maintenance There are many benefits to maintenance. Then what is the difference and relationship between the two?
1、Dry-type transformers are more expensive than oil-type transformers.
2、Oil-type transformers generally have a larger capacity than dry-type transformers. Dry-type transformers are generally suitable for power distribution. Most of the capacity is below 3000KVA, the voltage is below 35KV; while oil-type transformers can achieve full capacity and voltage levels from small to large. All voltages.
3、Use place comparison: Dry-type transformers are generally used in indoor, such as comprehensive buildings (basements, floors, roofs, etc.) and crowded places. Oil-type transformers are used in independent substations. Transformers in box substations generally use dry-type transformers, and oil-type transformers are generally used for outdoor temporary electricity use.
4、Oil-type transformers are larger than dry-type transformers. Therefore, when using oil-type transformers, more space is required, and dry-type transformers can only be used when the space is crowded.
5、dry-type transformers mostly use silicone rubber bushings, while oil-type transformers mostly use porcelain bushings. Comparison of load bearing capacity-Generally dry-type transformers should be operated at rated capacity, while oil-type transformers have better overload capacity.
