The utility model discloses a laminated-screen composite transposed conductor, belonging to electric equipment technical field, which comprises two bundles of the same transposed conductors; wherein, the two bundles of the same transposed conductors are made in advance and arranged in parallel axially; a screen wire which comprises four copper strips is arranged between the two bundles of the parallel transposed conductors; the external periphery of the four copper strips are covered by insulating paper; the four copper strips are contacted with each other in the narrow face, arranged orderly and used as shield; an outer pack insulation layer is arranged on the outer flank of the two bundles of the parallel transposed conductors. The utility model has the advantages of being applicable to the transformer winding of the direct current power network key equipment and satisfying the specific transformation requirement of AC-to-DC in the power network transportation.
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 prepare high voltage, high-capacity direct current Transformer Winding.
Technical background
So-called transposed conductor is meant by certain radical (odd number is as 31,45) enameling copper strap wire, overlap into two row by wide contact, on request on two row enamelled wires and below do the same transposition that turns to along leptoprosopy, and make the lead that multilayer closely holds composition continuously with electrician's insulating tape, be used to make high voltage, high-power transformer or other electrical equipment winding.In the past, this transposed conductor all was that sub-thread is identical from head to tail, and this transposed conductor is difficult to satisfy such as the special transformer performance requirement by interchange-DC converting.
Summary of the invention
The purpose of this utility model is proposing a kind of novel combined shifting lead, is used for making the special transformer winding of power transmission and transformation network direct current conveying by " interchange-direct current ".
The utility model proposes combined shifting lead, axially form side by side by two strands of identical transposed conductors making in advance, between two strands of transposed conductors arranged side by side, be provided with the screen line of forming by 4 copper strap wires, these 4 copper strap wire peripheries are surrounded by insulating paper, and be in contact with one another at leptoprosopy, arrange in order, as shielding.These 4 copper strap wires do not allow overlapping mutually, and are super wide to avoid size, influence shield effectiveness, also do not allow the gap simultaneously, avoid producing leakage field, see shown in Figure 2.Be provided with outsourcing insulation in two bursts of transposed conductor outsides arranged side by side.
In the utility model, the structure of sub-thread transposed conductor and manufacture method are conventional structure and manufacture method.This sub-thread transposed conductor is constituted by 2n+1 root enameling copper strap wire, and wherein, n root copper strap wire overlaps into row by wide, two row between be provided with lining paper, whole sub-thread transposed conductor outer felt around outside be surrounded by insulating barrier, its structure is as shown in Figure 1.Wherein, n=12-22, the thickness of every copper strap wire is identical, and width is also identical, and thickness is generally 1.1-2.0mm, and width is 4.5-9mm.
In the utility model, middle copper strap wire as the screen line, the width of every copper strap wire is 5-8mm, and thickness is 0.8-1.2mm, and the thickness of insulating layer in two bursts of transposed conductor outsides arranged side by side is 0.4-1.0mm.
The folder screen combined shifting lead of the utility model design can be used for preparing high voltage, high-capacity direct current Transformer Winding, can satisfy the specific (special) requirements by " interchange-direct current " in power transmission and transformation network direct current is carried of this kind transformer.
Description of drawings
Fig. 1 is a sub-thread transposed conductor sectional view.
Fig. 2 is folder screen combined shifting lead sectional view.
Number in the figure: 1 is copper strap wire, and 2 is paint film layer, and 3 is insulating barrier, and 4 are lining paper between row, and 5 is transposed conductor, and 6 are the screen line, 7 insulating barriers for the screen line, and 8 is outsourcing insulation.
Embodiment
Illustrated in figures 1 and 2, the structure of sub-thread transposition layer line 5 is made by common technology as shown in Figure 1.Wherein, single copper strap wire 1 thickness is 1.9mm, and width is 5.7mm, n=18, and the thickness of the lining paper 4 between two row copper strap wires is 0.8mm, and outsourcing insulation 3 adopts because of Su Duer paper (insuldur), and thickness is 1mm.Two strands of middle screen lines 6 of transposed conductor are rearranged by leptoprosopy by 4 copper strap wires, and the thickness of every copper strap wire is 0.8mm, and width is 6.2mm.The screen line insulating layer 7 of outsourcing adopts because of Su Duer paper, and thickness is 1.6mm.The outer felt of two strands of transposed conductors adopts because of Su Duer paper around the insulating barrier 8 of outsourcing, and thickness is 0.6mm.During preparation, adopt two-step process.Be that wherein one transposed conductor elder generation and four single copper strap wires (screen line) through the insulating barrier parcel position, arrange earlier specifically, hold by equipment temporarily, to guarantee each lead accurate positioning, fixing, reliable (this holds layer and need remove) when secondary formally makes up, reach (as 2000m) closing quotation after the requirement fixed length.Wire harness and another strand transposed conductor with this occasional combination carries out the secondary combination again, before combination interim lapping layer removed with the method for casting off a skin.Adopt this manufacture method, guaranteed between two strands of transposed conductors the position, in proper order, gap, requirement such as fixing, the unsurmountable technical difficulty of having avoided the six roots of sensation (thigh) to bring when making up simultaneously.
So-called " method of casting off a skin " is promptly before once interim wrapped, in the side of transposed conductor, before the wrapped machine first wrapped cage, pre-buried one 0.3～0.5 nylon wire is wrapped up the wire harness that has made up with cheap wrapping paper more temporarily, fastening location, accurate to guarantee each line position.And before take-up, use applying adhesive tape on wrapping paper, and when secondary is wrapped, only need nylon rope is pulled out, at once interim paper is torn disengagement, owing to be sticked together by adhesive tape between the every circle of wrapping paper.So wrapping paper is removed just as the snake slough skin, does not promptly pollute the operation place, damage wires not again.Like this, make and remove interim bag paper place and formal bag paper place, and each line two ends all fixed at a distance of tighter, thus make displacement, the gap increase, problem such as loose is all solved.
