Specializing in the production and sale of High-frequency transformers skeleton and SMD skeleton and other electronic materials

BOBBIN types and characteristics

Category Common Transformer skeleton can be summarized as follows:
1, divided by the number of phases:
1) single-phase transformer: used for single-phase and three-phase transformer load group.
2) three-phase transformer: three-phase system for raising and lowering the voltage.
2, according to the cooling points:
1) dry-type transformers: to rely on air convection for cooling, generally used for local lighting, electronic circuits and other small capacity transformers.
2) oil-immersed transformers: to rely on oil as a cooling medium, such as oil-immersed self-cooled, oil-cooled, oil cooled and forced oil circulation.
3, according to purpose:
1) Power transformers skeleton: for outputting liter distribution system voltage drop.
2) Instrument Transformers: The voltage transformers, current transformers for measuring instrumentation and protection equipment.
3) test transformer: can generate high-pressure, high-voltage electrical equipment test.
4) Special Transformer: If furnace transformer, rectifier transformers, transformers and other adjustments.
4, according to the form of winding points:
1) two-winding transformer: used to connect the two power system voltage levels.
2) three-winding transformer: Usually substation for power system area, connecting three voltage levels.
3) autotransformer appliances: used to connect different voltage power system. Also can be used as an ordinary boost or drop after transformer.
5, according to the core in the form of points:
1) core BOBBIN: a high-voltage power transformers.
2) shell-type transformers: Special transformers for high-current, such as electric transformers, welding transformers; or used in electronic equipment and television, radios and other power transformers.
