Abstract

The utility model discloses a parallel composite transposition lead which comprises two groups of copper flat wires, wherein the outside of single group of copper flat wires is coated with an internal insulating paper layer; the two groups of copper flat wires are axially arranged in parallel; and the outsides of the two groups of copper flat wires are coated with external insulating paper layers. The transposition lead has large section surface, large voltage volume, good insulating effect and stronger breakdown resisting capability, and can be widely used for winding of high-voltage high-capacity transformer coils of 500KV, 750KV, megavolt and the like.

Description

Parallel composite transposed conductor
Technical field
The utility model relates to transformer coil in a kind of power equipment, specifically a kind of parallel composite transposed conductor.
Background technology
Present common transposed conductor is twisted into wide overlapped winding wire by several to tens enameled sheet wires through the transposition of transposition head and forms, in order to adapt to the requirement of high voltage, high-power transformer coil winding, the used enameled sheet wire size radical increasing, enameled sheet wire of transposed conductor also gets more and more.Because the restriction of production equipment and process conditions, the radical of enameled sheet wire is relevant with the strand cage number of transposition unit, at present the strand cage of transposition unit has 48,56,88 etc. several substantially, enameled sheet wires success, lead talking over the wire easily, the loosing circle that should not replace after surpassing 88, the production operation difficulty, properties of product are difficult for controlled.The enameled sheet wire size is big more, pitch of transposition, transposition bending more difficult control, and enameled sheet wire is because stressed big, and impaired, the size of causing easily insulating changes, and technology is difficult for controlled.
Summary of the invention
In order to overcome the problem that existing common transposed conductor exists, the purpose of this utility model provides a kind of parallel composite transposed conductor, this transposed conductor sectional area is big, voltage capacity is big, good insulating effect, breakdown characteristics is stronger, can be widely used in the coiling of high voltage high-power transformer coils such as 500KV, 750KV and hundred Wan Fu.
The purpose of this utility model is achieved through the following technical solutions:
A kind of parallel composite transposed conductor is characterized in that: this parallel composite transposed conductor comprises two groups of copper strap wires, insulating paper layer in coating outside single group copper strap wire; Two groups of copper strap wires are axially arranged side by side; Outside two groups of copper strap wires, coat the external insulation ply of paper.
In the utility model, described single group copper strap wire is the single transposed conductor that is made of common enameled sheet wire.
The utility model is adjusted the transposition production technology, transposition earlier, and then it is compound that two transposed conductors are carried out parallel connection (the height face is overlapping) outsourcing insulating paper.
The utility model sectional area of wire is bigger, and voltage capacity increases, and insulation effect is better, and breakdown characteristics is stronger, can be widely used in the coiling of high voltage high-power transformer coils such as 500KV, 750KV and hundred Wan Fu.Product testing shows, parallel composite transposed conductor has stronger adaptability during " AC-DC " special transformation in electrical network is carried.Use the transformer effect of parallel composite transposed conductor satisfied.
Description of drawings
Fig. 1 is the process chart of parallel composite transposed conductor;
Fig. 2 is a structural representation of the present utility model.
Embodiment
A kind of parallel composite transposed conductor described in the utility model is seen Fig. 2, and this parallel composite transposed conductor comprises two groups of copper strap wires 1, insulating paper layer 2 in coating outside single group copper strap wire 1; Two groups of copper strap wires 1 are axially arranged side by side; Outside two groups of copper strap wires 1, coat external insulation ply of paper 4.
Fig. 1 is the process chart of parallel composite transposed conductor.At first copper coin is processed into the copper bar, obtains enameled sheet wire through wire drawing, enamelling process then, make single transposed conductor, again that two transposed conductor parallel connections are compound, obtain the parallel composite transposed conductor finished product.Single group copper strap wire 1 is the single transposed conductor that is made of common enameled sheet wire.Earlier common enameled sheet wire is carried out insulating paper layer 2 in the outsourcing, obtain single transposed conductor, again that two overlapping outsourcing external insulation ply of papers 4 in parallel of transposed conductor height face are compound.Like this because sectional area of wire increases, and voltage capacity is bigger, again because solid conductor is coated with insulating varnish outward, transposed conductor outsourcing insulating paper, two transposed conductors be the outsourcing insulating paper again, makes insulation effect outstanding, resist wear, the Short Circuit withstand performance is excellent more.Though increased the in parallel compound operation of transposed conductor one, whole production is easy and simple to handle, technical maturity is controlled, properties of product are guaranteed.

Claims (2)

1. parallel composite transposed conductor, it is characterized in that: this parallel composite transposed conductor comprises two groups of copper strap wires (1), insulating paper layer (2) in the outer coating of single group copper strap wire (1); Two groups of copper strap wires (1) are axially arranged side by side; Outside two groups of copper strap wires (1), coat external insulation ply of paper (4).
