TSTY's fully sealed oil-immersed power transformer is a marvel of engineering excellence. Crafted with precision, it offers
remarkable advantages: low loss, minimal noise, and exceptional efficiency. This innovative design ensures significant energy savings and reduces environmental impact. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. It features an advanced corrugated oil tank that automatically adjusts and compensates for oil volume changes through the elasticity of the corrugated sheet. This design isolates the transformer from air exposure, thereby preventing oil degradation and insulation aging. It significantly improves operational reliability and eliminates the need for maintenance under normal operating conditions.
Key Components:
This exceptional transformer comprises several pivotal parts: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is specifically designed to immerse the windings, ensuring optimal cooling and protection.
2. Complies with stringent IEC standards and is certified with CE/ISO for unmatched reliability.
3. Facilitates easy contact and expansion during load variations, allowing seamless temperature adjustments of the oil.
4. The Buchholz relay, utilized in systems with a conservator tank, detects issues such as oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel that absorbs moisture from the oil, changing from blue to pink when saturated, indicating the need for replacement.
6. The oil indicator reliably shows the oil level within the conservatory unit, ensuring proper monitoring.
7. The temperature detector continuously monitors the oil temperature and disconnects the transformer from service if it exceeds safe levels.
8. The pressure relief device effectively reduces internal pressure, preventing potential transformer explosions.
9. The thermal relay acts as a precise indicator of the winding temperature, ensuring safety and efficiency.
10. Features a full galvanized coating, ensuring complete rust resistance and durability.
11. The bushing connects the internal windings of the transformer with the external electrical network, ensuring seamless integration.
