Abstract

The utility model relates to an ultra-thin transposed conductor which is mainly used for manufacturing windings of a large-scale oil-immersed power transformer, a reactor and the like. The ultra-thin transposed conductor is formed in a mode that ultra-thin enamelled copper flat wires (1) are combined into two rows of the ultra-thin enamelled copper flat wires (1) of which wide surfaces are contacted; both upper and lower surfaces of the two rows of ultra-thin enamelled copper flat wires (1) are transposed in the same rotating direction along narrow surfaces as required; insulating paper, an insulating paper board or a shielding wire (2) is clamped between the two rows of ultra-thin enamelled copper flat wires (1); and then electrical insulating paper, an electrical insulating rope or an electrical insulating mesh tape (3) is used as a winding wire for continuously lapping. The thickness of the ultra-thin enamelled copper flat wire conductor is less than 1.0mm. The eddy-current loss of the transformer can be greatly reduced. The ultra-thin transposed conductor has wide prospect.

Description

Ultra-thin transposed conductor

Technical field

The utility model relates to a kind of transposed conductor, particularly a kind of ultra-thin transposed conductor.Be mainly used in the winding of making large oil immersed power transformer and reactor etc.

Background technology

Along with country advocates the low-carbon economy theory; comprehensively implement environmental protection and resource-effective requirement; national grid is when building intelligent grid; temperature rise to transformer requires also just more and more stricter; and the thickness of the temperature rise of transformer and winding conducting wire has direct relation, adopts ultra-thin transposed conductor can reduce the temperature rise of hot spot of transformer coil.Usually Transformer Winding is about 1.5mm with the single enameling copper strap wire conductor thickness of transposed conductor, and the eddy current loss that exists transformer is big, wastes energy and the dissatisfactory deficiency of electric property.

Summary of the invention

The purpose of this utility model is to remedy the deficiencies in the prior art, and provides a kind of rational in infrastructure, can satisfy the new type superthin transposed conductor of low-carbon (LC), environmental protection and energy-conservation requirement.

For achieving the above object, the utility model adopts following technical proposals: ultra-thin transposed conductor, mean that the ultra-thin enameling copper strap wire with certain radical is combined into two row that wide face is in contact with one another, on request two row ultra-thin enameling copper strap wire above and below do the same transposition that turns to along leptoprosopy, and, make wrapped winding wire continuously with electrician's insulating paper, rope or guipure then at two row ultra-thin enameling copper strap wire therebetween insulating paper, insulating board or shielding conductors etc.

The conductor thickness of above-mentioned ultra-thin enameling copper strap wire is less than 1.0mm.

Since square being directly proportional of the eddy current loss of transformer and conductor thickness, so lead is thin more, the eddy current loss of lead itself is more little, thus the temperature rise of hot spot of reduction transformer coil; And, also reduced the stray loss of transformer simultaneously because eddy current loss reduces, and also just having reduced the load loss of transformer, the size of having dwindled transformer has to a certain extent reduced the cost of transformer.The thickness of enameling copper strap wire conductor of the present utility model can reduce the eddy current loss of transformer, promise well greatly less than 1.0mm.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

With reference to Fig. 1, ultra-thin transposed conductor, be combined into two row that wide face is in contact with one another by ultra-thin enameling copper strap wire 1, on request two row ultra-thin enameling copper strap wire 1 above and below do the same transposition that turns to along leptoprosopy, and, make wrapped winding wire continuously with electrician insulating paper, rope or guipure 3 then at therebetween insulating paper, insulating board or the shielding conductor 2 of the ultra-thin enameling copper strap wire 1 of two row.

The conductor thickness of ultra-thin enameling copper strap wire 1 is a; The conductor width of ultra-thin enameling copper strap wire 1 is b.

The conductor thickness a of above-mentioned ultra-thin enameling copper strap wire 1 is less than 1.0mm.
