Classification of high-voltage transformers:
1. Classified by function:
Voltage transformer: such as JDZ series
Current transformer: such as LZZB series
2. Classified by filling material:
Oil type transformer: internally filled with insulating oil
Dry Type Transformer: filled with epoxy resin internally
3. According to the closure level
Semi enclosed transformer: For example, the corner shaped JDZ transformer, wiring terminals, and other parts are exposed, while other parts are enclosed.
Fully enclosed transformer: The whole body is enclosed.
In AC circuits, transformers are commonly used to convert high voltage into low voltage, and large current into small current, which is then used for measurement, control, and protection. This not only increases the range of measuring instruments, facilitates instrument standardization, reduces the voltage and current of control and protection equipment, but also isolates the instruments from equipment or high-voltage circuits, ensuring the safety of instruments, equipment, and personnel.
