Abstract
The utility model belongs to the electrical apparatus technical field, and particularly relates to a PET polyester film transposed conducting wire; and an insulating layer composed of a PET polyester film is wrapped outside the core of the transposed conducting wire. Because the externally wrapped material has the properties of high temperature resistance, withstand voltage, good mechanical strength, chemical corrosion protection, good thermal conductivity and anti-static, etc., the transposed conducting wire can be used for manufacturing gas transformers, such as sulfur hexafluoride (SF6) transformer windings, and can satisfy the special requirements of the gas transformers.
Description
Technical field
The utility model belongs to technical field of electrical equipment, is specifically related to a kind of transposed conductor that is used to make environment-friendly type variable pressure gas device winding.
Technical background
At present, the transformer in uses such as inner city, stadiums mostly adopts the variable pressure gas device.This transformer adopting gas has the characteristic of low pollution, low noise, nothing discharging as coolant.Very strict to the being perfectly safe property and the environmental requirement of transformer simultaneously.And make the lead that Transformer Winding is used usually, its heart yearn can be many enameling copper strap wires, be divided into two row that wide face is in contact with one another, on request on two row enamelled wires and below do the same transposition that turns to along leptoprosopy, constitute heart yearn bundle (finished product is a transposed conductor).This lead mostly adopts insulating paper to make insulating barrier, and all there are deficiency in its heat conductivility, antiseptic property.
Summary of the invention
The purpose of this utility model is to propose a kind of thermal conductivity and antiseptic property is good, mechanical strength is high transposed conductor.
The transposed conductor of the utility model design, its heart yearn is made up of odd number root enameling copper strap wire, and wherein, the enameling copper strap wire of equal number coincides mutually at wide, is arranged in two row, between two row lining paper layer is arranged; And two row enameling copper strap wires top and followingly do along leptoprosopy and turn to transposition constitutes the sub-thread heart yearn; The outer felt of heart yearn around outside be surrounded by PET polyester film insulating barrier.The thickness of insulating barrier is 0.4-2.0mm; Lining paper layer thickness between two row is 0.075-0.13mm.
In the utility model, the thickness of single enameling copper strap wire is 1.1-2.0mm, and width is 4.5-9mm.
In the utility model, the radical of enameling copper strap wire is 2n+1 in the sub-thread heart yearn, and n is the overlapping radical of every row enameling copper strap wire, and n is generally the integer of 4-35.
The utility model proposes a kind of by the PET polyester film be insulating bag around transposed conductor, make lead have of the requirement of variable pressure gas device winding to wire characteristic, make transformer satisfy environmental protection (low emission, low dry sound, low radiation), chemical defence, corrosion-resistant characteristic, and have proof voltage intensity, a mechanical strength classes height, heat conduction is fast, good cooling results, fail safe is good, to advantages such as public's harmfulness are few.
Description of drawings
The transposed conductor structural profile diagram that Fig. 1 designs for the utility model.
Number in the figure: 1 is copper strap wire, and 2 is paint film layer, and 3 is the lining paper layer, and 4 is PET polyester surrounding layer.
Embodiment
Is that two row coincide with 5～71 odd number root enameling copper strap wires by certain structure shown in Figure 1, the centre has the lining paper layer to isolate, form sub-thread core bundle, twine 4～20 layers of PET mylar tape of outsourcing then, carry out continuous, tight, uniformly overlapping wrapped, every layer of edge pressure 2～4mm forms uniformity, the tight insulation surrounding layer of smooth transposed conductor.Wherein, the thickness of enameling copper strap wire is 1.1-2.0mm, and width is 4.5-9.0mm, must accomplish in the production process that the production scene prevents floating dust, antistatic, and anti-high temperature, other liquids such as anti-machine oil pollute.In the close factory building of full envelope, finish.
In addition, in the utility model, heart yearn also can be the combined wire harness that is formed by certain principle combinations by above-mentioned many (as the 2-4 root) sub-thread heart yearns, and outsourcing 4-20 layer PET mylar tape is formed the insulation surrounding layer then.
Claims (4)
1, a kind of PET polyester film transposed conductor, it is characterized in that heart yearn is made up of odd number root enameling copper strap wire, wherein, the enameling copper strap wire of two groups of equal numbers coincides mutually at wide, be arranged in two row, between two row lining paper layer is arranged, and two row enameling copper strap wires top and followingly make the same transposition formation heart yearn that turns to along leptoprosopy; The outer hand hay cutter of heart yearn twines the outer PET polyester film insulating barrier that is surrounded by; The thickness of insulating barrier is 0.4-2.0mm, and the lining paper layer thickness between two row is 0.075-0.13mm.
2, PET polyester film transposed conductor according to claim 1, the radical that it is characterized in that described enameling copper strap wire is 2n+1, and n is the overlapping radical of every row enameling copper strap wire, and n is the integer of 4-35.
3, PET polyester film transposed conductor according to claim 1 is characterized in that described insulating barrier is made of every layer of edge pressure 2-4mm continuous, tight, smooth overlapping the holding of 4-20 layer PET mylar tape.
4, PET polyester film transposed conductor according to claim 1 is characterized in that heart yearn is the combined wire harness that many sub-thread heart yearns combine.
