High Voltage Wound Core Traction Transformer for Railway, Power Plant

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.

Application

Power plants, substation, large-scale industries, etc.
 

Range

Voltage level: 110 kV, 220kV

Voltage regulation: ±2×2.5%, ±3×2.5%, ±4×2.5%

Capacity: 8000kVA~63000 kVA

Features

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.

Parameter
