Abstract
The invention relates to a manufacturing method of a stair type combined transposed conductor. The method includes the following steps that the transposed conductor is formed in the mode that insulation varnish coats a bare copper flat wire to form an enamelled flat wire, and then 5 to 83 enamelled flat wires are transposed and wrapped by a transposed conductor isolating layer; two transposed conductors form a set, a stair type combined transposed conductor isolating layer winds the outsides of the two transposed conductors, and an isolating paper board is arranged between the two transposed conductors; after the requirement for the needed length is met in production, one of the two transposed conductors in the set is cut off and is connected with one side of the other one, which is not cut, of the two transposed conductors in the set; the transposed conductor on the upper portion is cut and moved to the position where the transposed conductor on the lower side is located, isolating layers wrap the outer sides of the two adjacent transposed conductors, and a connector isolating protective layer wraps the lap joint portion of the transposed conductors. The transposed conductor is simple in structure, reasonable in design, reliable in performance, capable of effectively guaranteeing isolating performance, simple in manufacturing process, capable of greatly reducing manual operation difficulty and labor intensity, and remarkable in effect.
Description
Technical field
The present invention relates to a kind of manufacture method for converter transformer coil windings line, particularly a kind of manufacture method of staged combined shifting lead.
Background technology
At present, when AC extra high voltage converter transformer coil windings, when transformer centre position winding and peripheral hardware assembling, conventionally need to manually leave the end of a thread, the subsequent treatment work such as joint insulating wrapped are also by manually completing, a large-scale power transformer is generally highly more than two meters, so not only to have strengthened manually-operated difficulty and labour intensity; Also exist after coiling transformer, several sections of line voltage gradients of stem are fallen suddenly, end winding voltage skewness simultaneously, and external lightning once in a while impacts, operation is closed a floodgate etc. causes first section of voltage instantaneous to increase tens times to damage turn insulations, cause the drawbacks such as transformer is fragile.
Therefore, continually develop novel product to adapt to the demand in market, a kind of manufacture method of staged combined shifting lead is provided, the staged combined shifting lead of producing can effectively solve an above-mentioned difficult problem, improves conforming product rate, raises labour productivity.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, the manufacture method of the staged combined shifting lead of a kind of simple in structure, simple process, dependable performance is provided.
The technical solution adopted in the present invention is for achieving the above object: a kind of manufacture method of staged combined shifting lead, is characterized in that making step is as follows:
This transposed conductor is to form enameled sheet wire after applying insulating varnish outward by bare copper flat wire, then by many enameled sheet wires outer cladding transposed conductor insulating barrier after transposition, produces single transposed conductor; If one group of two outer wrapped staging pack transposed conductor insulating barrier of single transposed conductor, sandwiched insulating board between two transposed conductors, in production, reach after Len req requirement, wherein one of one group of two single transposed conductor is cut off, continued access is to a side of not cutting short one; The single transposed conductor of upside is cut off to the position that moves to the single transposed conductor of downside, two adjacent coated splice insulation protective layers of transposed conductor outside coated staging pack transposed conductor insulating barrier ， transposed conductor lap-joint.
The invention has the beneficial effects as follows: the present invention is the manufacture method of staged combined shifting lead for a kind of UHV, and this transposed conductor is applicable to converter transformer coil windings; This transposed conductor is simple in structure, reasonable in design, and performance safety is reliable, has effectively guaranteed the insulation property of transposition line; Manufacturing process simple process, greatly reduces manually-operated difficulty and labour intensity, effect highly significant.
Accompanying drawing explanation
Fig. 1 is the staged combined shifting lead structural representation that the inventive method is made;
Fig. 2 is the staged combined shifting lead schematic cross-section that the inventive method is made;
In figure: 1 bare copper flat wire, 2 enameled sheet wires, 3 transposed conductor insulating barriers, 4 staging pack transposed conductor insulating barriers, 5 insulating boards, 6 splice insulation protective layers, 7 single transposed conductors.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, details are as follows for feature:
As shown in Figure 1 and Figure 2; a manufacture method for staged combined shifting lead, this transposed conductor manufacturing process comprises bare copper flat wire 1, enameled sheet wire 2, transposed conductor insulating barrier 3, staging pack transposed conductor insulating barrier 4, insulating board 5, splice insulation protective layer 6 and single transposed conductor 7.
This transposed conductor making step is as follows:
This transposed conductor is by forming enameled sheet wire 2 after the outer coating insulating varnish of bare copper flat wire 1, then by many enameled sheet wires 2 outer cladding transposed conductor insulating barrier 3 after transposition (existing production technology), produces single transposed conductor 7; If sandwiched insulating board 5 between one group of two outer 4, two transposed conductor of wrapped staging pack transposed conductor insulating barrier of single transposed conductor; For example, after production reaches Len req (71.939 meters) and requires, one in one group of two single transposed conductor to be cut off, continued access is to a side of not cutting short one; Referring to Fig. 1, the single transposed conductor 7 of upside is cut off to the position that moves to the single transposed conductor 7 of downside, two adjacent coated splice insulation protective layers 6 of transposed conductor outside coated staging pack transposed conductor insulating barrier 4 ， transposed conductor lap-joints.
Described enameled sheet wire 2 adopts 5-83 root.
Transposed conductor insulating barrier 3 can adopt electrician's insulating paper, and thickness is 0.065mm-0.105mm.
Staging pack transposed conductor insulating barrier 4 can adopt electrician's insulating paper, and thickness is 0.065mm-0.105mm.
Insulating board 5 can adopt electric insulation cardboard, and thickness is 0.5mm.
Splice insulation protective layer 6 can adopt electrician's insulating paper, and thickness is 0.065mm-0.105mm.
Above-mentioned detailed description of the manufacture method of this staged combined shifting lead being carried out with reference to embodiment, is illustrative rather than determinate, therefore in the variation and the modification that do not depart under general plotting of the present invention, within should belonging to protection scope of the present invention.
