wound core traction transformer
Wound core traction transformer is a kind of energy-saving transformer adopts wound core technology. 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. The product is suitable for electrified railway AT power supply system.
Power plants, substation, large-scale industries, etc.
Voltage level: 110 kV, 220kV
Voltage regulation: ±2×2.5%, ±3×2.5%, ±4×2.5%
Capacity: 8000kVA~63000 kVA
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.
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 140 ºC.
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.
Low partial discharge
Strictly control each part of the electric field intensity, according to the discharge requirements, coil winding and internal assembly is in the dustproof workshop to guarantee the body clean, adopts the high vacuum oil injection process, effectively control discharge of product.
