Pioneering with precision, the fully sealed oil-immersed power transformer crafted by TSTY showcases unparalleled innovation.
This modern marvel boasts the advantage of low loss, whisper-quiet operation, and exceptional efficiency. It not only ensures an impressive energy-saving performance but also contributes to pollution reduction. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The ingenious corrugated oil tank's elasticity automatically adjusts and compensates for changes in oil volume. This transformer is hermetically isolated from the air, effectively preventing oil degradation and insulation aging, thereby enhancing operational reliability and virtually eliminating maintenance during normal operation.
Main Components:
The principal components of this state-of-the-art 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 critical function of immersing the windings, ensuring efficient cooling and insulation.
2. Built to meet IEC standards and proudly certified with CE/ISO credentials.
3. Designed for seamless contact and thermal expansion to manage oil temperature fluctuations effectively.
4. The Buchholz relay, essential when a conservator tank is utilized, detects faults such as oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit, equipped with silica gel, absorbs moisture in the oil and changes color from blue to pink when saturated, indicating it's time for replacement.
6. The oil indicator provides a clear reading of the oil level within the conservatory unit, ensuring optimal operation.
7. The temperature detector continuously monitors the oil temperature, triggering a disconnection if levels become too high to prevent damage.
8. The pressure relief device is engineered to reduce internal pressure, preventing potential transformer explosions.
9. The thermal relay acts as an essential temperature indicator for the windings, ensuring safety and efficiency.
10. Features full galvanized coating to prevent rust, ensuring longevity and durability.
11. The bushing connects the internal windings with the external electrical network, facilitating seamless operation.
