Three-phase oil-immersed power transformer voltage is suitable for three-phase power systems of 50 Hz, 10 KV, 20 KV, 35 KV and below. It is the main transformer equipment of small and medium-sized substations for industrial, agricultural power distribution, power and lighting.
Implementation Standards: GB1094.1-2-1996 Power Transformers, GB1094.3, 5-2003 Power Transformers
Technical parameters and requirements of GB1094.4-2005 power transformer and GB/T6451-2008 three-phase oil-immersed power transformer
Compared with S9 transformer, the no-load loss of this series transformer is reduced by about 30% on average.
Low-voltage windings with capacity ranging from 630 kvA to 2000 kvA adopt barrel or spiral structure with high mechanical strength, balanced ampere-turn distribution and good short-circuit resistance.
The positioning structure is added to the body so that no displacement occurs during transportation. At the same time, all fasteners are equipped with fastening nuts to ensure that the fasteners are not loosened during the long-term operation of the product and meet the requirements of no suspension core.
The transformer adopts corrugated oil tank, eliminating oil storage tank. The cover and edge of the tank are completely welded or fastened by bolts, thus prolonging the service life of transformer oil.
After degreasing, embroidery and phosphating, the surface of the product can be sprayed with primer and topcoat, which can meet the special requirements of metallurgical, petrochemical systems and wet and polluted areas.
Selected components adopt fully sealed transformer oil tank. Pressure release valves, signal thermometers, gas relays are installed according to the standard requirements to ensure the safe operation of transformers. This series of products have beautiful appearance, small volume, and can reduce the installation area. It is an ideal maintenance-free high-quality product.
