The innovative fully sealed oil-immersed power transformer, crafted by TSTY ELECTRIC CO., LTD., boasts unparalleled
advantages such as minimal energy loss, whisper-quiet operation, and exceptional efficiency. This transformer delivers outstanding energy-saving performance while mitigating environmental pollution. Unlike traditional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume adjustment is seamlessly managed by the flexibility of the corrugated sheet in the corrugated oil tank. By isolating the transformer from air, we effectively prevent oil degradation and insulation aging, significantly enhancing reliability and virtually eliminating the necessity for maintenance during normal operation.
Main Components:
This transformer is comprised of several vital components, including the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank immerses the windings, ensuring optimal cooling and insulation.
2. Adheres to IEC standards and comes with CE/ISO certifications.
3. Designed for easy contact and expansion during loading, allowing the oil temperature to fluctuate effectively.
4. The Buchholz relay is essential for conservator tanks, detecting issues such as oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs oil moisture. Its color change from blue to pink indicates its saturation level.
6. The oil indicator displays the oil level within the conservator unit.
7. The temperature detector monitors the oil temperature and disconnects the transformer from service if it exceeds safe levels.
8. The pressure relief device mitigates internal pressure to prevent transformer explosions.
9. The thermal relay acts as a temperature indicator for the windings.
10. Fully galvanized coating ensures resistance against rust.
11. The bushing facilitates the connection between the transformer's internal windings and the external electrical network.
