 The single phase transformer that is the winding on primary and secondary are single. The single phase transformer has simple structure, small volume and low loss which suitable for low density low-voltage network. Because of simple

structure of single phase transformer that suitable for mass modern production to the benefit of improving products quality. In the theoretical calculation of line loss, it can be found that 80% of the line loss occurs in 20% of the

main trunk, so shortening the distance of the low-voltage main trunk can greatly reduce the low-voltage line loss. Because of the light weight of the single-phase transformer, it can be flexibly installed on the pole for use, which is

convenient for going deep into the load center, reducing the voltage nearby and improving the power supply quality. General single-phase transformer in a small range of power supply, fault wave and surface small, conducive to improve

the reliability of power supply .At the same time, because of the light weight of single-phase transformer, easy installation and maintenance, flexible use, can be used single-phase, also can be three three-phase transformer.

 

In order to reduce the line loss of the low-voltage main trunk, the high-voltage line should be introduced into the load center to increase the investment in the construction of high-voltage line. The no-load loss and load loss of single phase transformer are more than that of single large capacity transformer. The purchase fund of multiple single-phase transformers is also larger than that of single large-capacity transformers. The construction of single-phase

power supply system in light-load areas can reduce the construction investment. The transformation of single-phase power supply system in heavy load area must have larger economic input.
