The fully sealed oil-immersed power transformer developed by TSTY ELECTRIC CO., LTD. offers a transformative advantage with
benefits such as low loss, minimal noise, and exceptional efficiency. This design achieves remarkable energy-saving effects while significantly reducing environmental pollution. Unlike conventional oil-immersed transformers, this innovative fully sealed transformer eliminates the need for an oil conservator. The dynamic oil volume is automatically regulated and compensated by the elasticity of the corrugated sheets in the oil tank, isolating the transformer from air exposure. This results in prolonged oil integrity, delayed insulation aging, enhanced operational reliability, and maintenance-free performance under typical conditions.
Main 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, providing optimal insulation and cooling.
2. Complies with IEC standards and carries CE/ISO certifications.
3. Ensures easy contact and expands during load variations, enabling the oil temperature to rise and fall accordingly.
4. The Buchholz relay is essential when a conservator tank is present, detecting issues such as 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 accurately displays the oil level within the conservator unit.
7. The temperature detector monitors oil temperature, automatically disconnecting the transformer if the temperature exceeds safe limits.
8. The pressure relief device mitigates internal pressure to prevent transformer explosions.
9. The thermal relay serves as an indicator of the winding temperature.
10. Features full galvanized coating to ensure rust-free operation.
11. The bushing links the internal windings of the transformer to an external electrical network.
