Introducing TSTY's fully sealed oil-immersed power transformer, a marvel of engineering.
Boasting low loss, low noise, and unparalleled efficiency, , this transformer promises remarkable energy-saving potential and significant pollution reduction. Unlike conventional oil-immersed transformers, our fully sealed variant eliminates the need for an oil conservator. The innovative design allows the oil volume to be automatically adjusted and compensated by the flexible corrugated sheet of the tank. Encapsulated to isolate from air, this transformer slows oil deterioration and insulation aging, enhancing operational reliability and ensuring maintenance-free performance during regular operation.
Mainly Components:
The main components of this transformer include the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank serves the crucial role of immersing the windings in oil, providing essential cooling and insulation.
2. Complies with IEC standards and holds CE/ISO certifications
3. Designed for ease of contact and expansion during load variations, ensuring efficient temperature regulation of the oil.
4. The Buchholz relay is essential when a conservator tank is in use. It detects issues such as low oil levels and improper oil flow between the tank and transformer, ensuring early error indication.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil. It serves as an indicator by changing color from blue to pink when it can no longer absorb moisture.
6. The oil indicator provides a clear view of the oil level within the conservatory unit, ensuring optimal operation.
7. The temperature detector continuously monitors the oil temperature. If it rises beyond safe levels, the transformer is automatically disconnected to prevent damage.
8. The pressure relief device mitigates internal pressure to prevent transformer explosions, ensuring safety.
9. The thermal relay acts as a thermal indicator for the windings, providing crucial data on winding temperature.
10. Fully galvanized coating ensures rust-free performance and longevity.
11. The bushing connects the transformer's internal windings with the external electrical network, facilitating seamless power distribution.
