Introduction of Traction Transformer
TUNGWELL's liquid-filled substation transformers are designed, built, and tested in accordance with international standards including IEC 60076, GB1094, ANSI C.57, CSA, NEMA and IEEE. The insulating liquid can be mineral oil, high flash point ester fluid and silicon oil. The product is suitable for electrified railway traction power supply system.
Usually, the transformer core is laminated type, and our wound type core is also possible if required by customer, Wound core traction transformer is a kind of energy-saving transformer with many outstanding advantages: Low no-load loss, low no-load current, low noise, strong anti-short circuit ability and overload capacity, the transformer is energy efficient and environmentally friendly.
Range
- Voltage level: 2×27.5kV/27.5kV
- Capacity: 5000kVA~40000 kVA
Technical characteristics
Low no-load loss, low no-load current, low noise
The cores are wound tightly without any juncture, reducing magnetic resistance and noise; Its cross section is inscribed polygon, high fill factor. After high temperature annealing of eliminating stress, no-load loss is greatly reduced.
Low impedance
Use multiple splitting structures to reduce impedance and adjust core diameter, number of turns, splitting group to make the impedance value small enough.
Strong overload capacity
With oil flow guide control technology, the quantitative calculation of the oil flow, optimize the structure of oil circuit, reduce the hot-spot coefficient, to ensure that under the condition of rigorous overloading load, the winding hot-spot temperature does not exceed 140ºC.
Strong anti-short circuit ability
By analyzing and calculating the worst short circuit, adopting high strength wire and effective support to strengthen the structure, adjusting the coil distribution to ensure all stress have enough margin. Self-developed winding technology can make the coils wind tightly.
