Description
Technical field
The present invention relates to a kind of transformer, particularly relate to environment protection H-grade insulation dry transformer.
Background technology
Dry-type transformer has three kinds at present, one, resin casting dry-type transformer manufacturing process complexity, and instability, the price height moves one section and goes out crack performance, and discharge has no idea to solve.Burning has dense smoke, produces noxious substance.Two, wrapped formula dry-type transformer manufacturing process equipment complexity, prices of raw and semifnished materials height, heat dispersion is poor.Three, dipping dry-type transformer manufacturing process is simple, and humidity resistance is poor, and overload capacity is low, and to sum up all there is the technical deficiency part in three kinds of dry-type transformers, all do not reach optimum efficiency in electrical operation.
Summary of the invention
The present invention has overcome the deficiency on the existing Dry-Transformer Technology, and a kind of class of insulation height, environmental protection and energy saving, little, the lightweight environment protection H-grade insulation dry transformer of being convenient to move of volume are provided.
A kind of environment protection H-grade insulation dry transformer, comprise iron core, high-tension coil, low-voltage coil, high-low pressure insulating cylinder, end insulation, it is characterized in that: the H class F insulating material F is adopted in insulating cylinder and end insulation, the insulating cylinder outside is provided with stay, be provided with cushion block between the coil conductor layer, this cushion block matches fixing with stay; Transformer clamps by board-like folder up and down, with the tension of nonmagnetic steel plate, passes through to press nail fixing by high frequency glass silk fiber briquetting.
Iron core adopts 45 ° of complete oblique three-dimensional seams, with the high magnetic conduction silicon steel sheet of high-quality grain orientation, forms through shearing closed assembly.
Be provided with temperature control system in the space between inside and outside insulating cylinder.
The winding wire of high-tension coil and low-voltage coil adopts the NOMEX paper covered wire.
Cushion block adopts high frequency glass silk fiber cushion block.
Stay adopts high frequency glass silk fiber stay.
The bottom is provided with ventilating system, adopts the transverse ventilation cooling system.
The present invention compared with prior art, beneficial effect is described below:
1, the present invention adopts NOMEX paper and other H class F insulating material F phase configuration, and the class of insulation reaches the H level, the heat-resisting C level that reached of critical component insulation, and perfect heat-dissipating, the thermal life is long.Transformer can bear temperature rise 125T, can reach 145T during overload, 40 ℃ of ambient temperatures, 185 ℃ of maximum temperatures.
2, the present invention adopts the lead that the high magnetic conduction of high-quality has orientation low-loss cold-reduced silicon sheet and high-quality oxygen-free copper bar to draw, and the iron loss of transformer is lower than with 15% of capacity SG type, and copper loss is lower than with capacity SG type 10%.
3, TRANSFORMER INSULATING MATERIAL of the present invention is a flame retardant type, and insulating material is all not combustion-supporting, and burning capacity is extremely low, in the burning down of 800 ℃ of high temperature, non smoke, does not decompose noxious substance, and is free from environmental pollution.The insulating material good springiness is difficult for wearing out, and life-span height, transformer first phase are easy to after useful life decompose, and reclaim, and transformer has fault to keep in repair well.
4, safe, hundred-percent waterproof ability, no partial discharge phenomenon is a dry-type transformer updated article of new generation.
In sum, the present invention has that volume is little, in light weight, thermal diffusivity is good, insulating properties is high, advantages such as overload capacity is strong, good electric property.
