TSTY's fully sealed oil-immersed power transformer boasts advanced engineering.
It offers remarkable benefits: low loss, minimal noise, and outstanding efficiency, resulting in exceptional energy savings and reduced pollution. Unlike standard oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. Instead, it automatically adjusts the oil volume through the elasticity of the corrugated oil tank. This design ensures that the transformer remains isolated from air, preventing oil degradation and insulation aging. This enhances operational reliability and virtually eliminates maintenance during standard operation.
Mainly Components:
The primary components of this high-performance transformer include: 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 for efficient cooling and insulation.
2. Complies with IEC standards and comes with CE/ISO certifications for assured quality and safety.
3. Designed for easy connectivity and expansion, allowing the oil temperature to efficiently rise and fall.
4. The Buchholz relay, ideal for conservator tank setups, detects issues such as oil leaks and improper oil flow, promptly signaling errors.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil, indicating its capacity by changing color from blue to pink when saturated.
6. The oil indicator provides a clear reading of the oil level within the conservator.
7. The temperature detector meticulously monitors the oil temperature, ensuring disconnection if it exceeds safe limits.
8. The pressure relief device mitigates internal pressure to prevent potential transformer explosions.
9. The thermal relay indicates the winding temperature, safeguarding the transformer from overheating.
10. Features a full galvanized coating to prevent rust, ensuring longevity.
11. The bushing facilitates a secure connection between the transformer's internal windings and the external electrical network.
