20kv distribution transformer
2025.02.25
A 20kV distribution transformer is a device used in power distribution systems, mainly used to reduce high voltage (such as 20kV) to a low voltage suitable for user use (such as 380V/220V). This type of transformer is commonly used in urban and rural distribution networks to ensure safe and stable power supply to households and industrial users.
###Main features:
- Voltage level: 20kV is one of the standard voltage levels for high-voltage distribution systems, suitable for medium voltage distribution networks.
- Power level * *: The power level of a 20kV distribution transformer usually ranges from several hundred kilovolt amperes to several thousand kilovolt amperes to meet the needs of different users.
- Cooling method * *: Oil immersed or dry cooling methods are generally used. Oil immersed transformers are cooled by transformer oil and are suitable for high-power transformers; Dry type transformers use air cooling, which is suitable for small power and special environments.
- Insulation Material * *: High quality insulation materials are usually used on the high-voltage side to ensure safe operation under high voltage.
- Protective measures * *: Distribution transformers are generally equipped with safety devices such as overload protection and short circuit protection to prevent equipment damage and accidents such as fires.
###Application areas:
-Residential area: provides electricity for household users.
-Industrial Zone: Provides stable power supply for factories and enterprises.
-* * Business District * *: Provides power to commercial facilities such as shopping malls and office buildings.
###Maintenance and Management:
-Regularly check the oil level, temperature, and insulation status of the transformer.
-Monitor the load condition of the transformer to prevent overload.
-Clean the environment around the transformer and ensure good ventilation.
20kV distribution transformers play a crucial role in modern power systems, ensuring the safety and reliable supply of electricity.
