The cutting-edge fully sealed oil-immersed power transformer from TSTY ELECTRIC CO., LTD. stands out with its innovative design and advanced functionality.
This transformer boasts remarkable advantages such as low operational loss, minimal noise, and exceptional efficiency. These features culminate in outstanding energy-saving capabilities and a significant reduction in environmental pollution. Unlike conventional oil-immersed transformers, our fully sealed version eliminates the need for an oil conservator. Instead, the oil volume changes are managed automatically through the elasticity of the corrugated sheet in the oil tank. This design ensures the transformer remains air-isolated, which helps to prevent oil deterioration, slow insulation aging, enhance operational reliability, and eliminate the need for regular maintenance.
Main Components:
The main components of this high-performance 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 submerge and cool the windings efficiently.
2. Complies with IEC standards and certified by CE/ISO.
3. Ensures easy contact and expansion during loading, allowing for effective temperature regulation of the oil.
4. The Buchholz relay operates when a conservator tank is used, indicating issues such as oil loss and improper oil flow.
5. The Breather Unit contains silica gel that absorbs moisture; it changes color from blue to pink when it loses absorption capability.
6. The oil indicator shows the oil level within the conservator unit.
7. The temperature detector monitors the oil's temperature, disconnecting the transformer for safety if a certain threshold is reached.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay serves as an indicator for winding temperature.
10. Full galvanized coating ensures no rust.
11. The bushing connects the transformer’s internal windings to an external electrical network.
