The cutting-edge fully sealed oil-immersed power transformer by TSTY ELECTRIC CO., LTD. boasts remarkable features
such as ultra-low loss, minimal noise levels, and exceptional efficiency, delivering outstanding energy-saving performance and reducing environmental pollution. In comparison to the conventional
our fully sealed variant eliminates the need for an oil conservator. The transformer ingeniously adjusts the oil volume automatically using the elasticity of the corrugated sheet in the corrugated oil tank. This design isolates the transformer from the atmosphere, significantly slowing down oil degradation and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during normal operation.
Main Components:
The primary parts 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, ensuring optimal cooling and insulation.
2. Complies with IEC standards and holds CE/ISO certifications.
3. Facilitates easy contact and expansion during loading, allowing the oil temperature to rise and fall efficiently.
4. The Buchholz relay is essential with the conservator tank, signaling issues like oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel that absorbs moisture from the oil, changing color from blue to pink when saturated.
6. The oil indicator shows the oil level within the conservator unit.
7. The temperature detector keeps track of the oil temperature, disconnecting the transformer from service if a critical level is reached.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay acts as an indicator for the winding temperature.
10. Fully galvanized coating ensures a rust-free exterior.
11. The bushing connects the internal windings of the transformer to the external electrical network.
