Introducing TSTY's fully sealed, oil-immersed power transformer, a marvel of engineering that
boasts low loss, minimal noise, and exceptional efficiency . This innovative design not only delivers outstanding energy-saving benefits but also significantly reduces environmental pollution. Unlike traditional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. It features a corrugated oil tank whose elasticity adjusts and compensates for changes in oil volume automatically. This ensures the transformer remains isolated from air, thus preventing oil degradation and insulation aging. The result is enhanced operational reliability and maintenance-free performance under normal operating conditions.
Mainly Components:
The essential 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 is engineered to submerge the windings, ensuring optimal performance and cooling.
2. Complies with IEC standards and is certified with CE/ISO.
3. Allows for easy connection and expansion during load changes, facilitating efficient temperature regulation of the oil.
4. The Buchholz relay, essential for conservator tanks, alerts you to issues such as oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit, filled with silica gel, absorbs moisture from the oil, changing color from blue to pink when it can no longer absorb moisture.
6. The oil indicator provides a clear reading of the oil level within the conservator unit.
7. The temperature detector monitors the oil's temperature, and if it exceeds a certain threshold, it safely disconnects the transformer from service.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay acts as a temperature indicator for the windings.
10. Fully galvanized coating ensures no rust formation.
11. The bushing connects the internal windings of the transformer to an external electrical network.
