The fully sealed oil-immersed power transformer developed by TSTY ELECTRIC CO., LTD. showcases the
advantages of minimal energy loss, reduced noise levels, and exceptional efficiency , which collectively contribute to impressive energy-saving capabilities and environmental sustainability. Unlike standard oil-immersed transformers, this innovative fully sealed model eliminates the need for an oil conservator. The oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet within the corrugated oil tank. This design ensures the transformer remains isolated from air, preventing oil degradation and insulation aging. Consequently, this enhances operational reliability and eliminates the need for routine maintenance during normal operations.
Main Components:
The main 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 submerges the windings in oil to ensure effective cooling and insulation.
2. Complies with IEC standards and certified by CE/ISO.
3. Easily expand during loading to increase and decrease the oil temperature efficiently.
4. The Buchholz relay operates with a conservator tank, signaling issues such as low oil levels 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 once it is saturated.
6. The oil indicator shows the oil level within the conservator unit.
7. The temperature detector monitors the oil temperature, disconnecting the transformer from service if it reaches a critical level.
8. The pressure relief device mitigates excess pressure within the transformer, preventing explosions.
9. The thermal relay indicates the winding temperature.
10. Fully galvanized coating ensures rust resistance.
11. The bushing connects the internal windings to the external electrical network.
