Industrial Power Transformer Capacity And Number

1) The industrial power transformer capacity is generally selected according to the planned load of 5-10 years after the completion of the transformer, and the long-term load development of 10-20 years is properly considered.

2) For transformers with important loads, it should be considered that when one transformer is out of service, it can guarantee the user's Class I and II loads; for general transformers, when one transformer is out of service, the capacity of the remaining transformers should be able to guarantee the full load 70%-80% of that.

3) The industrial power transformer capacity of a single unit with the same level of voltage should be as few as possible. When the ring network has been formed on the middle and side, it is advisable to install two transformers for the transformer. For regionally isolated primary transformers or industrial-specific transformers. The possibility of installing 3-4 transformers should be considered in the design.

4) For industrial power transformer with only two Anhui transformers installed, it should be determined whether there should be a possibility of replacing a transformer with a larger capacity in light of the long-term development.
