What Should Be Paid Attention to During the Oil Immersed Transformer Selection Process?
1. Load characteristics When there are a large number of primary or secondary loads, two or more transformers should be installed. When any one of the transformers is disconnected, the capacity of the remaining transformers can meet the primary and secondary loads. First, the secondary load is as concentrated as possible and should not be too dispersed.
2. When the seasonal load capacity is large, a special transformer should be installed. Such as air conditioning refrigerator load in large civil buildings, electric heating load for heating, etc.
3. When the concentrated load is large, special transformers should be installed. Such as large heating equipment, large X-ray machines, electric arc furnaces, etc.
