Behold the 12500kVA 33/11kV Oil Immersed Power Distribution Transformer from TSTY ELECTRIC CO., LTD., engineered for unparalleled reliability and efficiency in power distribution.
The rated voltage can be customized according to customers' specific requirements, ensuring flexibility and tailored solutions for diverse needs.
TSTY proudly presents its fully sealed oil-immersed power transformer, a marvel of engineering that offers
unparalleled advantages, including low loss, minimal noise, and exceptional efficiency. This transformer is designed to deliver outstanding energy-saving performance and significantly reduce environmental pollution. Unlike traditional oil-immersed transformers, our fully sealed design 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, ensuring seamless operation. By isolating the transformer from air, we prevent oil deterioration and insulation aging, thereby enhancing operational reliability and minimizing maintenance during regular use.
Main Components:
This transformer is composed of essential parts including 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 in oil, providing effective cooling and insulation.
2. Our transformer complies with IEC standards and comes with CE and ISO certifications, ensuring high quality and reliability.
3. The conservator expands and contracts with the oil, allowing temperature regulation and maintaining optimal performance.
4. The Buchholz relay activates with a conservator tank to detect faults such as oil loss and improper oil flow, providing an early warning system.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil. When saturated, the gel changes color from blue to pink, indicating it needs replacement.
6. The oil indicator monitors the oil level within the conservator, ensuring consistent transformer performance.
7. The temperature detector continuously monitors the oil's temperature, disconnecting the transformer from service if temperatures exceed safe levels.
8. The pressure relief device safely reduces internal pressure to prevent transformer explosions, enhancing safety.
9. The thermal relay serves as an indicator for winding temperatures, ensuring efficient operation.
10. The transformer features a fully galvanized coating, ensuring long-term protection against rust.
11. The bushing connects the internal windings to the external electrical network, facilitating efficient electrical flow.
