Abstract
A composite conductor with different fillets and in the shape of rice field mainly solves the problems of fast temperature rise of the conductors, incompactly applied conductors, large loss of the leads, influence on product performance and reliability. The structure of the conductor is as below: four different fillet enamel-cover copper flat wires are contacted by right angle surfaces to form a rice field shape; and an electrician insulation paper belt is wound continuously for many layers so as to form a winding wire. Two out of four angles of each single enamel-cover copper flat wire are right angles, and the other two are fillets. The utility model employs a structure with different fillets and in rice field shape, so as to increase the number of copper flat wires, reduce corresponding cross section of a single wire and reduce eddy current loss of the winding; besides, compared with common copper flat wires, the rice field shape combination of copper flat wires with different fillets increases cross section and reduces winding temperature rise of the winding, so as to prolong service life of a transformer and reduce production cost of the transformer product. The product is mainly used for manufacture of large-scale oil-immersed power transformer and reactors, etc. and belongs to the technical field of power transmission and transformation.
Description
Technical field
The utility model relates to a kind of matrix pattern composite conductor, particularly a kind of different fillet matrix pattern composite conductor.Winding mainly for the manufacture of large oil immersed power transformer and reactor etc. belongs to the power transmission and transformation technical field.
Background technology
The structure of existing like product mainly contains following several: 1, the copper strap wire of composite conductor is two, because the sectional area ratio of its solid wire is bigger, makes eddy current loss increase, and the temperature rise that causes Transformer Winding easily is fast and influence the insulation property of product.2, the copper strap wire of composite conductor is four, but four angles of every lead are fillet, makes applying defective tightness between lead and the lead, and has reduced mechanical Strength for Winding, has influenced the transformer reliability of operation.Have, the utilance of its copper of winding of this kind structure is not high enough again, and electricity is close low, and loss is big, therefore, and to also affecting in useful life of transformer.
Summary of the invention
The utility model is purpose to address the above problem, and the composite conductor that mainly solves prior art is fast owing to the temperature rise that its structural reason causes, applying defective tightness and loss between the lead are big, and influences properties of product and reliability problems.
For achieving the above object, the utility model adopts following technical proposals: different fillet matrix pattern composite conductors, comprise different fillet enameling copper strap wires, with at least four different fillet enameling copper strap wires, be in contact with one another with the right angle face, be the matrix pattern shape and arrange, make multilayer wrapped and formation winding wire continuously with electrician's insulating paper strip then.Two is the right angle in four angles of the single enameling copper strap wire of it each, and two is fillet.
The beneficial effects of the utility model and advantage:
The utility model compared with prior art because it has adopted the structure of different fillet matrix patterns, this structure makes the copper strap wire radical increase, the cross section of single line is corresponding to be dwindled, and greatly reduces the eddy current loss of winding; On the other hand, adopting the copper strap wire of different fillets to carry out the matrix pattern combination compares with the ordinary copper lenticular wire of same size, the cross section has increased, reduced the winding temperature rise of transformer, simultaneously compare the utilance height of copper, electric close height with the copper strap wire of common fillet, reduce loss, thereby reached the purpose that prolongs transformer useful life, reduces the power transformer product production cost.Also because contacted of lead is the right angle, lead is fitted closely, increased mechanical Strength for Winding, improved the transformer reliability of operation.
