Power transformers are the main equipment for power transmission and distribution in power systems.
The electric energy produced by power plants is sent to high-voltage power grids through step-up transformers at the generator outlet, which raise the low voltage of 10-20kv to high voltage levels such as 220kv, and then sent to large substations through high-voltage transmission lines.
Transformers of different capacities complete the distribution of electric energy at various voltage levels. It is sent to the distribution center, and then the step-down transformer is used to reduce the transmission voltage to 35/110kv for distribution and sent to users. According to the needs of various power equipment and lighting electricity, it is reduced to 6/3kv and 380/220v.
When multiple substations are combined to form a power system, they also rely on various transformers to connect various voltages with lines to form a system. It can be seen that transformers play a very important role in the power system.
Single-phase pole mounted transformer serve as distribution transformer inthe distribution network of decentralized power supply, it has many advan-tages, such as reducing the length of low-voltage distribution line losses andimproving the power supply efficiency.It is designed with high-eficiency and energy-saving wound core structure,featuring pole-type suspension installation, small volume, small capitalinvestment,shorter low-voltage power supply radius, and over 99%%reductionin low-voltage line loss.With a fully sealed structure, the transformer hasstrong overload capability, high reliability in continue operating and easy to maintenance.
