The cutting-edge, fully sealed oil-immersed power transformer by TSTY features the
advantages of remarkably low loss, minimal noise, and outstanding efficiency, which collectively ensure excellent energy-saving capabilities and significantly reduce environmental pollution. In contrast to conventional oil-immersed transformers, this innovative, fully sealed model eliminates the need for an oil conservator. The variation in oil volume is seamlessly adjusted and compensated by the corrugated sheet's elasticity in the corrugated oil tank. This design isolates the transformer from air, thereby preventing oil degradation and insulation aging, enhancing operational reliability, and ensuring maintenance-free performance under normal operating conditions.
Main Components:
The primary components 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 is essential for immersing the windings in oil, offering superior insulation and cooling capabilities.
2. Complies with IEC standards and comes with CE/ISO certifications, ensuring top-notch quality and reliability.
3. Designed to easily adapt and expand during loading, allowing the oil temperature to rise and fall efficiently.
4. The Buchholz relay is activated with a conservator tank, signaling errors such as oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit features silica gel that absorbs moisture in the oil, changing color from blue to pink when it becomes saturated.
6. The oil indicator displays the oil level within the conservator unit, providing clear and accurate measurement.
7. The temperature detector monitors the oil temperature, disconnecting the transformer from service if temperatures reach critical levels.
8. The pressure relief device reduces internal pressure to prevent transformer explosions, ensuring safety.
9. The thermal relay acts as a temperature indicator for the winding, safeguarding the transformer by monitoring critical heat levels.
10. Fully galvanized coating ensures rust-free operation and longevity.
11. The bushing facilitates the connection between the internal windings of the transformer and the external electrical network, ensuring seamless integration.
