Our transformers ensure reliable three-phase step-down power conversion, making them the ideal choice for efficient oil-immersed distribution in various applications.
The rated voltage is customizable to meet the specific requirements of our valued customers.
The innovative fully sealed oil-immersed power transformer, meticulously developed by TSTY, boasts an impressive array of features:
• Low Loss: Minimize energy waste and maximize efficiency. • Low Noise: Operates quietly, ensuring a peaceful environment. • High Efficiency: Superior performance for optimal energy conversion. This advanced technology delivers exceptional energy-saving benefits and significantly reduces 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 elastic corrugated sheet within the corrugated oil tank. This innovative feature isolates the transformer from air exposure, preventing and mitigating oil degradation and insulation aging. As a result, it enhances operational reliability and ensures maintenance-free performance under normal operating conditions.
Main Components:
This exceptional transformer is composed of several vital 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 submerge the windings completely, ensuring optimal cooling and insulation.
2. Compliant with IEC standards and proudly bearing CE and ISO certifications.
3. This component is engineered for easy contact and expansion during load changes, allowing the oil temperature to rise and fall effectively.
4. The Buchholz relay is crucial for systems using a conservator tank, as it detects critical issues such as low oil levels and improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel that captures moisture from the oil. The gel changes from blue to pink when it has absorbed its maximum capacity of moisture.
6. The oil indicator precisely displays the oil level within the conservator unit.
7. The temperature detector continuously monitors oil temperature. If it exceeds a certain threshold, it will disconnect the transformer from the service to prevent damage.
8. The pressure relief device mitigates internal pressure, safeguarding the transformer from potential explosions.
9. The thermal relay functions as a temperature indicator for the winding, providing real-time data.
10. Fully galvanized coating ensures robust protection against rust.
11. The bushing facilitates the connection of internal windings to an external electrical network, ensuring seamless integration.
