I. Improve economic efficiency.
Transformer parallel connection involves connecting the primary and secondary terminals of two or more transformers with the same polarity to each other via the same busbar. When the load increases to the point that the capacity of one transformer is insufficient, other transformers can be connected in parallel; when the load decreases, the excess transformers can be taken out of operation.
Parallel connection of transformers allows for switching on and off according to the size of the electrical load, reducing transformer losses and improving operational economy.
II. Improve reliability.
When one of the transformers operating in parallel fails, as long as it is disconnected from the power grid, the other transformers can still supply power normally. During maintenance, as long as the transformer under maintenance is isolated, it will not affect the operation of other transformers, thus ensuring the reliability of the circuit.
At the same time, the improved reliability reduces the circuit failure rate and further enhances the economic efficiency of the transformer.
