Elevate your power management solutions with TSTY's high-performance, oil-immersed transformers designed to deliver superior distribution and operational longevity.
The rated voltage can be tailored to meet customers' specific requirements, providing unparalleled customization and flexibility.
The state-of-the-art fully sealed oil-immersed power transformer developed by TSTY offers exceptional performance and reliability.
This innovative transformer boasts low loss, low noise, and high efficiency, which leads to significant energy savings and reduced pollution. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet within the corrugated oil tank. Isolated from air, this transformer prevents oil deterioration and insulation aging, thus enhancing operational reliability and minimizing the need for maintenance during normal operations.
Main Components:
The essential parts 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 immerses the windings, providing efficient cooling and insulation.
2. Built to comply with IEC standards, this transformer boasts CE/ISO certification.
3. Designed for seamless contact, it effectively manages thermal expansion, ensuring steady temperature regulation of the oil.
4. The Buchholz relay, used with a conservator tank, signals issues like low oil levels and improper oil flow, enhancing system reliability.
5. The Breather Unit, containing silica gel, absorbs moisture in the oil. Its color change from blue to pink indicates saturation and necessitates replacement.
6. The oil indicator precisely shows the oil level within the conservatory unit, ensuring optimal operation.
7. The temperature detector continuously monitors the oil temperature, disconnecting the transformer if it reaches critical levels to prevent damage.
8. The pressure relief device mitigates internal pressure, preventing potential explosions.
9. The thermal relay serves as a crucial indicator for winding temperature, ensuring operational safety.
10. Fully galvanized coating ensures durability and rust resistance.
11. The bushing connects internal windings to the external electrical network, facilitating seamless power transmission.
