Oil-immersed transformers are one of the most widely used transformer devices in the power industry, generally installed in a separate transformer room. But when choosing the oil-immersed transformer, it is not just a transformer can meet the needs of users, must be integrated to consider. So, how to select oil-immersed transformer?
1.Consider the nature of the load, different use of the transformer load requirements are different.
2.Consider the environment of the use, in the normal medium conditions, we can choose oil-immersed transformers or dry-type transformers, such as industrial and mining enterprises, agricultural independent or attached to the substation, residential independent substation.
3.The choice of electricity load and capacity, the capacity of oil-immersed transformers need integrate the capacity of various electrical equipment to calculate the load, the apparent capacity after compensation is the basis for selecting the transformer capacity and the number of units. General transformer load rate is about 85%. This method is simpler and can be used for estimating capacity.
