Trust in TSTY ELECTRIC CO., LTD. for cutting-edge, oil-immersed distribution transformers that elevate your power infrastructure.
The rated voltage can be tailored to meet the unique specifications and requirements of our valued customers.
The state-of-the-art, fully sealed oil-immersed power transformer, meticulously developed by TSTY ELECTRIC CO., LTD., offers unparalleled
advantages such as ultra-low loss, minimal noise, and exceptional efficiency. This transformer not only delivers outstanding energy savings and significantly reduces pollution, but it also distinguishes itself from conventional oil-immersed transformers. The absence of an oil conservator allows for automatic adjustment and compensation of oil volume through the corrugated sheet's elasticity in the corrugated oil tank. Completely isolated from air, this design prevents oil degradation and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during standard operation.
Key Components:
The primary components of this advanced transformer include an 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, ensuring optimal cooling and insulation.
2. Compliant with IEC standards and accredited with CE/ISO certifications.
3. Facilitates easy contact and expansion during loading, allowing oil temperature to rise and fall efficiently.
4. The Buchholz relay is essential when a conservator tank is employed. It detects faults such as oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel, which absorbs moisture from the oil. It changes from blue to pink when saturated.
6. The oil indicator shows the oil level within the conservator unit, ensuring optimal operation.
7. The temperature detector monitors oil temperature. If it exceeds a safe threshold, the transformer disconnects from service to prevent damage.
8. The pressure relief device mitigates internal pressure to prevent transformer explosions.
9. The thermal relay indicates the winding temperature, providing crucial data for maintenance.
10. Full galvanized coating ensures no rust, extending the transformer's lifespan.
11. The bushing connects the internal windings to the external electrical network efficiently.
