TSTY proudly introduces its cutting-edge, fully sealed oil-immersed power transformer, designed with precision and innovation.
This transformer stands out for its remarkable features of low loss, minimal noise, and exceptional efficiency, delivering impressive energy-saving benefits and reducing environmental pollution. Unlike typical oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume adjusts automatically, thanks to the elasticity of the corrugated oil tank's sheet. This innovative approach isolates the transformer from air, significantly slowing oil degradation and insulation aging. It ensures superior operational reliability and maintenance-free performance during normal usage.
Main Components:
The main 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 designed to immerse the windings in oil, ensuring optimal cooling and insulation.
2. Complies with IEC standards and comes with CE/ISO certifications.
3. Facilitates easy contact and accommodates expansion during loading, allowing for temperature regulation and efficient operation.
4. The Buchholz relay is essential when using a conservator tank, as it detects issues such as oil level drops or improper oil circulation between the tank and the transformer.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil. It changes from blue to pink when it's saturated and can no longer absorb moisture.
6. The oil indicator shows the oil level within the conservator unit, ensuring proper monitoring.
7. The temperature detector continuously monitors the oil temperature. If the temperature exceeds a certain threshold, the transformer will automatically disconnect to prevent damage.
8. The pressure relief device reduces internal pressure to prevent transformer explosions, ensuring safety.
9. The thermal relay serves as a temperature indicator for the windings, providing critical feedback for operation.
10. Fully galvanized coating ensures no rust, extending the transformer's lifespan.
11. The bushing connects the internal windings of the transformer to the external electrical network efficiently.
