introduction of 35kV dry-type transformer
GNEE TRANSFORMER supplies 35kV dry-type on-load voltage regulating power transformer.
Dry transformer with OLTC are usually designed for larger voltage and capacity applications. Relying on the accurate and timely action of the on-load tap-changer (OLTC), it can not only reduce and avoid large fluctuations in grid voltage, but also force the distribution of loads, tap the reactive and active output of the equipment to ensure stable power system operation, it can meet the range of different regulation demands, flexible and convenient for operation.
Features
- 1.Safe, fireproof, pollution-free, can be run directly in the load center.
- 2. Adopt domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life.
- 3. Low loss, low noise, obvious energy-saving effect, maintenance-free.
- 4. Good heat dissipation performance, strong overload capacity, and can increase capacity operation when forced air cooling.
- 5. Good moisture-proof performance, adapt to high humidity and other harsh environment operation.
- 6. It can be equipped with perfect temperature detection and protection system. Adopting intelligent signal temperature control system, it can automatically detect and display the respective working temperature of three-phase winding, and automatically start and stop the fan, and have function settings such as alarm and tripping.
- 7. Small volume, light weight, occupying less space and low installation cost.
