Abstract
The utility model belongs to the technical field of electrical equipment and particularly relates to a Nomex insulating combined transposed conductor which comprises copper flat wires, a paper lininglayer and a Nomex insulating layer. A paint film layer is coated outside each copper flat wire, so as to form an enameled copper flat wire; the core wire of the transposed conductor comprises an uneven number of enameled copper flat wires, wherein the enameled copper flat wires of the same number are overlapped mutually on the wide side, so as to be arranged in two lines; the paper lining layer isarranged between the two lines; the upper surface and the lower surface of the two lines of enameled copper flat wires change the direction and the position along the narrow side so as to form a single strand of core wire; the Nomex insulating layer is twisted and wrapped on the outer side of the core wire; the insulating layer is 0.4 to 2.0 mm in thickness; and the paper lining layer 3 between the two lines is 0.09 to 0.12 mm in thickness. The transposed conductor provided by the utility model meets the requirements of a special transformer winding of ultra high voltage direct current to a conductor, thereby enabling a transformer to have the characteristics of high-temperature resistance, humidity resistance, environmental protection, chemical defense and corrosion protection as well asthe advantages of high degree of mechanical strength and voltage strength resistance, fast heat conduction, good cooling effect, good security, less harmfulness to the public and the like.
Description
Technical field
The utility model belongs to the electric equipment technical field, is specifically related to a kind of paper insulation combined shifting lead.
Background technology
For implementing energy-saving and cost-reducing, the macroscopical target of energy-saving and emission-reduction that country proposes, grid company adopts a kind of new DC converter transformer to substitute the conventional AC transformer at present, and is long apart from the line loss in the power delivery to reduce.The safety that need adapt to high temperature, humid climate and densely populated areas simultaneously in south.So Southern Power Grid Company begins to transform this kind transformer, wherein adopt Nomex (Nomex nylon) (Nomex) paper as wire insulation.Because that this insulating paper has is high temperature resistant (can be anti-200 ℃, and general wood fibre insulating paper is 120 ℃).
Summary of the invention
The purpose of this utility model is to propose a kind of thermal endurance and antiseptic property is good, electrical strength, Nomex (Nomex nylon) (Nomex) insulation combined shifting lead that mechanical strength is high of conducting heat.-
The Nomex (Nomex nylon) insulation combined shifting lead that the utility model proposes, form by copper strap wire 1, lining paper layer 3 and Nomex (Nomex nylon) insulating barrier 4, the every copper strap wire 1 outer paint film layer 2 that all is coated with, constitute enameling copper strap wire, 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, be arranged in two row, between two row lining paper layer 3 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 Nomex (Nomex nylon) insulating barrier 4, the thickness of this insulating barrier is 0.4-2.0mm; Lining paper layer 3 thickness between two row are 0.09mm-0.12mm.
In the utility model, the thickness of single enameling copper strap wire is 1.1-2.0mm, and width is 4.5-9.0mm.
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 5～71 odd number.
In the utility model, described Nomex (Nomex nylon) insulating barrier 4 is made up of continuous, tight, smooth overlapping the holding of 4-20 layer Nomex (Nomex nylon) paper, every layer of edge pressure 2-4mm.
In the utility model, heart yearn is the combined wire harness that many sub-thread heart yearns combine.
The lead that the utility model provides has the requirement of this special transformer winding of superhigh voltage DC to wire characteristic, make transformer satisfy high temperature resistant, humidity, environmental protection (low emission, low noise, 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
