Our rated voltage can be meticulously tailored to meet your precise requirements.
The state-of-the-art, fully sealed oil-immersed power transformer, engineered by TSTY, boasts an unparalleled combination of
exceptionally low loss, minimal noise, and outstanding efficiency, delivering remarkable energy-saving benefits while significantly reducing pollution. Unlike conventional oil-immersed transformers, our fully sealed variant eliminates the need for an oil conservator. The dynamic oil volume is adeptly managed and compensated through the flexible corrugated sheets of the tank, ensuring the transformer remains isolated from air exposure. This isolation curtails oil degradation and insulation aging, enhancing operational reliability and minimizing the necessity for maintenance during standard operations.
Key Components:
The essential parts of this high-performance transformer include an Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to immerse the windings, providing optimal cooling and insulation.
2. Adheres to IEC standards and certified with CE/ISO
3. Ensures seamless contact and expansion under load, effectively managing oil temperature fluctuations.
4. The Buchholz relay is vital when using a conservator tank, indicating issues such as low oil levels and improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil, changing color from blue to pink when saturated.
6. The oil indicator clearly shows the oil level within the conservator unit.
7. The temperature detector monitors oil temperature, disconnecting the transformer if it exceeds safe levels.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay serves as a temperature indicator for the windings.
10. Fully galvanized coating ensures complete rust resistance.
11. The bushing connects the transformer's internal windings to the external electrical network.
