The rated voltage of the transformer can be tailored precisely to meet our customers' unique requirements.
TSTY proudly presents its fully sealed, oil-immersed power transformer, setting new benchmarks in innovation.
It boasts remarkable features such as ultra-low loss, minimal noise, and exceptional efficiency. This transformer achieves outstanding energy conservation and significantly mitigates pollution. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume is automatically regulated and compensated by the flexible corrugated sheet of the oil tank, ensuring seamless operation. This ingenious isolation from the air prevents oil degradation and insulation aging, thereby enhancing operational reliability and virtually eliminating maintenance under normal conditions.
Main Components:
This exceptional transformer comprises key components such as 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 efficient cooling and insulation.
2. Complies with stringent IEC standards and holds CE/ISO certifications for unmatched reliability.
3. Ensures seamless contact and expands during loading to efficiently manage oil temperature fluctuations.
4. The Buchholz relay functions with the conservator tank, signaling errors such as low oil levels and improper oil flow between the tank and transformer.
5. The Breather Unit, containing moisture-absorbing silica gel, changes from blue to pink when saturated, indicating its effectiveness.
6. The oil indicator accurately displays the oil level within the conservatory unit, ensuring optimal maintenance.
7. The temperature detector monitors oil temperature, disconnecting the transformer from service if limits are exceeded.
8. The pressure relief device reduces internal pressure to prevent potential transformer explosions.
9. The thermal relay acts as a precise indicator for the winding temperature, ensuring safe operations.
10. Fully galvanized coating ensures rust-free durability and longevity.
11. The bushing connects the transformer's internal windings to an external electrical network, facilitating seamless power distribution.
