12500kVA 33/11kv Oil Immersed Power Distribution Transformer
The rated voltage can be tailored to meet the specific needs and requirements of our esteemed customers.
The innovative fully sealed oil-immersed power transformer from TSTY is engineered to provide
exceptional advantages such as low loss, minimal noise, and outstanding efficiency, delivering excellent energy-saving performance and environmental benefits. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. This innovation allows for automatic adjustment and compensation of oil volume through the elasticity of the corrugated oil tank's sheet. By being completely isolated from air, the transformer minimizes oil deterioration and insulation aging, significantly increasing operational reliability and reducing the need for maintenance during regular operation.
Mainly Components:
The primary components of this transformer include: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank submerges the windings, providing effective cooling and insulation.
2. Engineered to meet IEC standards, and certified with CE/ISO credentials.
3. Facilitates easy contact and expansion during load variations, ensuring efficient temperature regulation.
4. The Buchholz relay operates when a conservator tank is present, detecting faults like oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel to absorb moisture from the oil, changing color from blue to pink when moisture absorption capacity is exhausted.
6. The oil indicator displays the oil level within the conservator unit for easy monitoring.
7. The temperature detector keeps track of the oil temperature and disconnects the transformer if it rises beyond a safe threshold.
8. The pressure relief device mitigates excess pressure within the transformer to prevent potential explosions.
9. The thermal relay serves as a temperature indicator for the windings, ensuring optimal performance.
10. Full galvanized coating ensures longevity and prevents rust.
11. The bushing connects the internal windings to the external electrical network, facilitating seamless energy transfer.
