Control Transformer Dimension & Schematic Diagram
KNOWLEDGE BASE --- Transformer Introduction?
- Transformer Principle
A transformer is an instrument that transforms magnetic power into an electrical power and a device that changes AC voltage based on the electromagnetic induction principle.
- Transformer Sections
The main components of a transformer are magnetic iron core (magnetic section), primary winding and secondary winding (electrical sections). Its primary winding receives power, while the secondary section delivers energy. A magnet iron circuit introduced as the core is usually used to wrap these parts. Whereas these two primary and secondary coils are isolated electrically and are linked magnetically.
- Transformer Working Principle
Once current passes through the primary windings of the transformer, a magnetic field is generated, which generates a voltage in the secondary windings of the transformer. According to the type of application, single phase transformers are used to reduce or increase (step down or step up) the output voltage. This type of transformer is usually a power transformer with high efficiency and less waste.
- Transformer Function
The main functions of transformers are to convert voltage, convert current, convert impedance, isolate and stabilize voltage, etc.
