Description

Oil-immersed type transformer coil
Technical field
The utility model relates to a kind of transformer coil, particularly a kind of oil-immersed type transformer coil.
Background technology
Oil-immersed type transformer is the visual plant in power transmission and transforming equipment.Oil-immersed type transformer coil is the part in transformer, very large to the performance impact of oil-immersed type transformer.Traditional oil-immersed type transformer coil is circular, has increased difficulty like this for manufacturing, and transformer is empty, load loss is higher.
Summary of the invention
For the defect of prior art, the utility model provides a kind of oil-immersed type transformer coil.
A kind of oil-immersed type transformer coil, comprise the copper bar 1 that embeds coil Copper Foil 4, the two ends of described coil Copper Foil 4 are provided with coil insulation end 3, described coil Copper Foil 4 shapes are combined by two U-shaped rings and rectangle, and have at least two-layer, filler strip 2 is between described coil Copper Foil 4, and direction is identical with described coil Copper Foil 4 length directions, and pyrocondensation tightening belt 5 is wrapped on described coil Copper Foil 4.
Preferably, described filler strip 2 each other spacing equates, a filler strip circle of well-balanced arrangement formation.
The beneficial effects of the utility model are: manufacture easy, empty, load loss is low, strong, the high safety of stability during work.Be conducive to be set with after little to distance at iron core, steadiness is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model oil-immersed type transformer coil.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, it will be more clear making above-mentioned and other object of the present utility model, Characteristics and advantages.In whole accompanying drawings, identical Reference numeral is indicated identical part.Deliberately do not draw in proportion accompanying drawing, focus on illustrating purport of the present utility model.
As shown in Figure 1, oil-immersed type transformer coil of the present utility model, comprise the copper bar 1 that embeds coil Copper Foil 4, the two ends of described coil Copper Foil 4 are provided with coil insulation end 3, and described coil Copper Foil 4 shapes are combined by two U-shaped rings 6,7 and rectangle 9, and have at least two-layer, filler strip 2 is between described coil Copper Foil 4, direction is identical with described coil Copper Foil 4 length directions, and pyrocondensation tightening belt 5 is wrapped on described coil Copper Foil 4, and 8 is the hollow parts of coil Copper Foil.This manufacture and design easy, empty, load loss is low, strong, the high safety of stability during work.Be conducive to be set with after little to distance at iron core, steadiness is strong.Industrial frequency withstand voltage qualification rate is high, lead-in wire distributing order clear and definite, be convenient to phase sequence clear and definite, insulation distance meets specification requirement, and be conducive to sleeve pipe in lead-in wire.
Described filler strip 2 each other spacing equates, a filler strip circle of well-balanced arrangement formation.The Homogeneouslly-radiating that is conducive to coil, the performance of raising voltage device, reduces and uses the physics loss causing.
In above description, a lot of details have been set forth so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be implemented to be much different from alternate manner described here, so the utility model is not subject to the restriction of disclosed concrete enforcement above.Any skilled personnel are not departing from technical solutions of the utility model scope situation simultaneously, all can utilize method and the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Every content that does not depart from technical solutions of the utility model,, all still belongs in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to technical spirit of the present utility model.

Claims (2)
