The revolutionary fully sealed oil-immersed power transformer from TSTY ELECTRIC CO., LTD. offers unparalleled performance.
It boasts remarkable advantages such as low loss, minimal noise, and exceptional efficiency, delivering significant energy-saving benefits while contributing to environmental protection. Unlike conventional oil-immersed transformers, our state-of-the-art fully sealed transformer eliminates the need for an oil conservator. The oil volume is dynamically regulated and compensated by the corrugated sheet's elasticity within the corrugated oil tank, ensuring the transformer remains isolated from air exposure. This innovative design prevents oil degradation and insulation aging, significantly enhancing operational reliability. Moreover, it requires no maintenance under normal operating conditions.
Mainly Components:
The primary components of this high-performance 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 to immerse the windings, ensuring optimal cooling and insulation.
2. Adheres to stringent IEC standards and holds CE/ISO certifications for quality assurance.
3. Easily accessible and expandable during loading, allowing for efficient temperature regulation of the oil.
4. The Buchholz relay is vital when using a conservator tank. It detects issues such as low oil levels and improper oil flow between the tank and transformer, providing early warning signs of potential failures.
5. The Breather Unit contains silica gel that absorbs moisture from the oil, changing color from blue to pink when it can no longer absorb moisture, indicating the need for replacement.
6. The oil indicator displays the oil level within the conservatory unit, ensuring proper maintenance.
7. The temperature detector constantly monitors the oil temperature. Should the temperature exceed a set threshold, the transformer will automatically disconnect from service to prevent damage.
8. The pressure relief device mitigates internal pressure to prevent the risk of transformer explosions.
9. The thermal relay provides real-time temperature readings of the windings, ensuring safe operation.
10. Features a full galvanized coating to resist rust and extend the transformer's lifespan.
11. The bushing facilitates the connection between the internal windings of the transformer and an external electrical network, ensuring efficient power distribution.
