The fully sealed oil-immersed power transformer developed by TSTY boasts a remarkable design.
It features the advantages of low loss, low noise, and high efficiency, which collectively contribute to excellent energy-saving performance and pollution reduction. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The oil volume adjusts and compensates automatically through the elasticity of the corrugated sheet in the oil tank. This design ensures the transformer is isolated from the air, thereby preventing oil deterioration and insulation aging. As a result, operational reliability is significantly enhanced, offering maintenance-free operation under normal conditions.
Mainly 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 designed to immerse the windings in oil, ensuring optimal cooling and insulation.
2. Compliance with IEC standards, backed by CE/ISO certifications.
3. Facilitates seamless expansion and contraction during loading, enabling the oil temperature to increase and decrease efficiently.
4. The Buchholz relay, utilized with a conservator tank, indicates issues such as low oil levels or improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil. It turns from blue to pink when it can no longer absorb moisture.
6. The oil indicator shows the oil level within the conservatory unit.
7. The temperature detector keeps track of the oil's temperature. If it rises beyond a certain point, the transformer will be disconnected from service to prevent damage.
8. The pressure relief device reduces pressure within the transformer to prevent explosions.
9. The thermal relay acts as an indicator for the winding's temperature.
10. Fully galvanized coating ensures no rust formation.
11. The bushing connects the internal windings of the transformer to the external electrical network.
