Described many semihard copper strap wires are combined into two row that wide face is in contact with one another.
The number of plies that described polyester guipure twines is 1 layer.
The outer overlapping lapped insulation ply of paper of described polyester guipure removes when using coiling as protection.
Described being provided with between outer guipure and insulating paper layer torn rope.
The utility model advantage is:
1, the utility model is rational in infrastructure simple, manufactures easily, and cost is low.
2,, tack semihard transposition core is to increase the epoxy coating with self-adhesion characteristic to form on the basis of common acetal paint envelope curve, after winding transposition wire becomes winding, in the winding drying, bonding together mutually between enamelled wire from adhesive coating layer, making between the single enamelled wire can integral body of for good and all bonding one-tenth, thereby has improved whole transposed conductor and mechanical Strength for Winding greatly.
3, semi-hard conducting wire has improved the mechanical strength of lead self by particular processing technology, and self-adhesion and semihard transposed conductor have all improved the anti-sudden short circuit ability of winding in various degree, and both share the effect that can reach better.
4, the self-adhesive layer on polyester guipure and enamelled wire surface (epoxy heat bonding lacquer) in the winding drying course, can bond together, thereby further improves globality, intensivism and the mechanical strength of transposed conductor.
5, transposition core bottom or top can be provided with crimped paper as required, prevent that lead slides mutually when coiling, damage outer field guipure.
6, above-mentioned transposed conductor is compared with traditional paper insulation transposed conductor, has good conductivity of heat, and rapid heat dissipation can reduce the operation temperature rise of transformer, increases the service life, and occupies little space because of insulating barrier simultaneously, can reduce volume of transformer, saves cost.

Embodiment
A kind of netted rope binding type self-adhesion acetal semihard enamel-cover transposed conductor, comprise the transposition core, the transposition core comprises many semihard copper strap wires, and semihard copper strap wire outside scribbles the insulation enamelled coating, the insulation enamelled coating is the acetal enamelled coating, and described single acetal paint envelope curve outside scribbles self-adhesive layer; Described transposition core outside is surrounded with the polyester guipure, and the outer wrapped outer layer insulation paper of described polyester guipure is provided with lining paper between described transposition core, lining paper is a known technology in this area, and relevant criterion is arranged.Transposition core bottom can be provided with aromatic series paper or crimped paper as required.
Self-adhesive layer is an epoxy heat bonding enamelled coating, and many semihard copper strap wires are combined into two row that wide face is in contact with one another.The number of plies that the polyester guipure twines is 1 layer, and outer layer insulation paper is overlapping wrapped in polyester guipure outside, is provided with between outer guipure and insulating paper layer and tears rope.
Tack semihard transposition core is to increase the epoxy coating with self-adhesion characteristic to form on the basis of common acetal paint envelope curve.The many self-adhesion semihard acetal enameling copper strap wires of making in advance, be combined into two row that wide face is in contact with one another by certain radical, on request on two row enameled sheet wires and below do the same transposition that turns to along leptoprosopy, be twisted into enamelled wire heart yearn bundle, after winding transposition wire becomes winding, in the winding drying, bonding together mutually between enamelled wire from adhesive coating layer, making between the single enamelled wire can integral body of for good and all bonding one-tenth, thereby has improved whole transposed conductor and mechanical Strength for Winding greatly.Semi-hard conducting wire then is when producing solid conductor, has improved the mechanical strength of lead self by particular processing technology.Self-adhesion and semihard transposed conductor have all improved the anti-sudden short circuit ability of winding in various degree, and both share the effect that can reach better.
Lead is by the tack acetal enamel-cover semihard made in advance transposition core, carries out continuously with the polyester webs band then that rhythmic to hold binding fastening.This polyester guipure bonds together with the self-adhesive layer (epoxy heat bonding lacquer) on enamelled wire surface in the Transformer Winding dry run.The outer surface of the transposition core of forming at singularization root semihard enameling copper strap wire bundlees with the polyester webs band of transformer oil resistant, and can be as required add lining paper between core replacing, and the bottom is provided with aromatic series paper or crimped paper.
At the wrapped one deck insulating paper of skin, adopt overlapping wrappedly, protect netted insulating barrier, when coiling uses, pull in outer insulating paper the prepositioned rope of tearing and remove outer field insulating paper.Tearing the line that rope is common similar setline, being placed between outer guipure and insulating paper layer, in use; pullling line scratches insulating paper; remove insulating paper, the purpose of insulating paper is to get final product in order to protect whole lead not to be damaged in transportation, to remove when using coiling.
Can in transposition core bottom or top crimped paper be set as required in addition; Perhaps behind wrapped guipure insulating barrier, the aromatic series paper of being with tack is set on the bottom or the top of transposed conductor.Prevent that lead slides mutually when coiling, damage outer field guipure.
The hardness of lead is according to degree national standard JB/T6758-2007, different requirement of mechanical strength, the regulation disproportional extension strength Rp0.2:C1 Rp0.2 (〉 100 ~ 180 of double hard copper conductor) N/ mm
2C2 Rp0.2 (〉 180 ~ 220) N/ mm
2C3 Rp0.2 (〉 220 ~ 260) N/ mm
2Can be controlled at 0 ~+10% according to different hardness requirements, make hardness more uniform and stable, dispersed little.According to different electric insulation requirements, can select thin paint film 0.08-0.11mm or paste paint film 0.12-0.16mm for use, the self-adhesive layer thickness of hot sticky enameling copper strap wire is generally 0.03-0.05mm.Can produce the insulating varnish layer thickness according to customer requirement.
Replace conventional insulating paper wrapped with guipure as skin, its radiating effect be other kind transposed conductors can't compare, use netted insulation to come secure wires, the lacquer that relies on enamelled wire itself is as insulating between line, the guipure of special material is then selected in public insulation for use, the conductor of winding coil is directly contacted with transformer oil, eliminate the oil sac between insulating paper and lead, help improving the heat dispersion of transformer; Simultaneously can also reduce the size of oil duct, and can reduce the external diameter value of transformer, the manufacturing cost of transformer is further reduced.
