Product Introduction
This series of products are suitable for high fire protection requirements, large load fluctuations and dirty and humid environments. Such as: airports, power plants, metallurgical operations, hospitals, high-rise buildings, shopping centers, densely populated areas, as well as petrochemical, nuclear power plants, nuclear submarines and other special environments.
Executive standards
2.1 IEC60076-11:2004 Dry-Type Power Transformer 2.2GB1094.1-1996 Power Transformer
2.3GB1094.11-2007 Dry Type Power Transformer
2. Technical parameters and requirements of 4GB/T10228-2008 dry-type power transformer
2.5 JB/T10088-2004 6kV ~ 500kV Power Transformer Sound LevelModel and its meaning
Performance characteristics
The 4.1 has good heat dissipation conditions, long thermal life, extremely strong overload capacity, and can operate at full load for a long time without forced air cooling under 120% long-term overload conditions.
4.2 high safety and flame retardant performance, no smoke generated at 800 ℃ high temperature long combustion
4.3 strong thermal shock resistance (can be immediately full load at 50 ℃)
4.4 hundred percent waterproof sealing, excellent hydrophobicity, moisture resistance.
4.5 the unique coil structure and strong field calculation, the product is almost no partial discharge.
The 4.6 loss is low and the energy saving effect is remarkable. Compared with SC9 series dry-type transformer, the no-load loss is reduced by 10% on average and the load loss is reduced by 5%.
After the 4.7 life, the insulation material and copper wire can be easily separated and recycled without polluting the environment.
Structural features
5.1 unique porcelain insulation structure, using MORA insulation Jane and high-frequency ceramic pads, never deformation
The 5.2 high and low voltage coils are made of DuPont N0MEX insulation material, and are impregnated with special formula H-class insulation paint for many times by VP1 vacuum pressure equipment. After baking and curing for many times, the coils are sealed with high-strength insulation material. And high temperature curing. The high-voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation conditions.
The 5.3 core material is made of high-quality high-permeability silicon steel sheets stacked, with a 45-degree full-tilt structure, and an elastic fixing device is used between the winding and the core, so that the transformer has lower no-load loss and noise. The surface of the core is treated by special process. The iron core is moderately clamped by the pull screw, the upper and lower clamps are connected by the pull plate and fixed with the base as a whole, the winding is fixed by the elastic pad, and the buffer structure can reduce the vibration degree of the winding and reduce the noise.
The 5.4 lead terminal is fixed on the upper part of the winding, the tap is in the middle of the winding, and the low-voltage lead terminal is a plate conductive bar, and argon arc welding is used.Product Parameters
