Customized Various Models
1. Classification by use 1. Step-up transformer: mainly used to increase low voltage to high voltage to meet the needs of long-distance power transmission.
In power plants and substations, step-up transformers are usually connected to generators and transmission lines to step up the electrical energy generated by the generator and transmit it to distant locations.
2. Step-down transformer: used to reduce high voltage to the low voltage required by users to meet the needs of various electrical equipment.
Step-down transformers are usually installed in substations or near users to provide appropriate voltage for various electrical equipment.
3. Contact transformer: used to connect two power grids with different voltage levels to achieve interconnection between power grids.
Contact transformers play an important role in regional grid interconnection and improving grid power supply reliability.
2. Classification by number of phases 1. Single-phase transformer: a transformer with only one winding, usually used for single-phase loads or special needs.
Single-phase transformers have a simple structure, but when used in a three-phase system, multiple units need to be connected in parallel to achieve high visibility of the three-phase balance.
2. Three-phase transformer: A transformer with three windings used for power conversion in three-phase power systems.
Three-phase transformers are widely used in power systems and can meet most power needs.
3. Classification by cooling method 1. Dry-type transformer: uses natural cooling or forced air cooling to dissipate heat, and is suitable for indoor or dry environments.
