What are the classifications of transformers?
There are various ways to classify transformers, and they are classified differently from different perspectives. The classification is mainly based on criteria such as usage, structure, and cooling method. The following are common classifications and specific explanations:
1、 Classified by purpose
1. Power Transformer: Used for voltage conversion and energy transmission in power systems, including step-up transformers, step-down transformers, and distribution transformers.
2. Special transformers: designed for specific scenarios, such as electric furnace transformers, rectifier transformers, test transformers, mining transformers, etc.
3. Instrument transformers: used for measurement and protection, such as current transformers and voltage transformers.
4. Voltage regulating transformer: voltage regulation is achieved by adjusting the winding turns ratio, which is divided into two types: no-load voltage regulation and on load voltage regulation.
