Abstract
The utility model relates to a heatproof reinforced mesh belt binding transposed wire which is composed of bare copper flat wires, composite paint insulating layers, a polyester mesh belt insulating layer, a Dennison paper layer, and a Nomex layer. Each bare copper flat wire is coated with the composite paint insulating layer to form an enameled copper flat wire, and a plurality of the enameled copper flat wires are transposed by a transposition device to become an enameled core wiring harness. The bottom of the enameled core wiring harness is pasted with the Dennison paper layer, and the enameled core wiring harness pasted with the Dennison paper layer is coated with the polyester mesh belt insulating layer. The polyester mesh belt insulating layer is coated with the Nomex layer, and the Nomex layer is arranged on the bottom of the Dennison paper layer. The transposed wire bottom of the heatproof reinforced mesh belt binding transposed wire can carry out the electrical insulation and the heat isolation among wires after the molding of a transformer coil winding. Because the heatproof reinforced mesh belt binding transposed wire is arranged inside the winding, the temperature rise of the winding is higher than a contact surface of the winding to a transformer liquid coolant. With the help of the two added insulating papers, the electrical performance and the high temperature resistance performance of the transformer are effectively enhanced.
Description
Technical field
The utility model belongs to the electric equipment technical field, is specifically related to a kind of heat-resisting reinforced guipure binding transposed conductor.
Background technology
So-called guipure binding transposed conductor is by the many enameling copper strap wires of making in advance, carries out rhythmic transposition on special use transposition production equipment, is twisted into enamelled wire heart yearn bundle, carries out continuously with the polyester mesh 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, thereby further improves globality, intensivism and the mechanical strength of transposed conductor.This 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.
But, the electrical strength of heart yearn bundle is decreased owing to cancelled traditional paper insulation in the prior art.Particularly behind the coiling, lead is in contact with one another face and lacks that insulating protection easily produces Lou, creepage phenomenon, influences safe in utilization.
Summary of the invention
The purpose of this utility model is to provide a kind of heat-resisting reinforced guipure binding transposed conductor.
The heat-resisting reinforced band binding transposed conductor that the utility model proposes, by bare copper flat wire 1, compound varnished insulation layer 2, polyester webs tape insulation layer 3, Dan Nisong ply of paper 4 and Nomex (Nomex nylon) layer 5 are formed, wherein: all be coated with compound varnished insulation layer 2 outside the every bare copper flat wire 1, constitute enameling copper strap wire, many enameling copper strap wires are through the transposition of transposition equipment, be twisted into enamelled wire heart yearn bundle, enamelled wire heart yearn bundle bottom is pasted with Dan Nisong ply of paper 4, the enamelled wire heart yearn bundle that posts Dan Nisong ply of paper 4 is coated with polyester webs tape insulation layer 3, polyester webs tape insulation layer 3 external pasting have Nomex (Nomex nylon) layer 5, and Nomex (Nomex nylon) layer 5 is positioned at the loose ply of paper of red layer 4 bottoms.
In the utility model, described Dan Nisong ply of paper 4 is made of individual Dan Nisong paper, and Dan Nisong paper thickness is 0.075mm.
In the utility model, described compound varnished insulation layer 2 adds the compound lacquer of epoxy self-bonding by the polyester acetal and constitutes.
Manufacture method of the present utility model is as follows: heat-resisting reinforced guipure binding transposed conductor, after being the Dan Nisong paper that 0.075mm of lining is thick bottom transposed conductor enamel-cover heart yearn bundle before the guipure binding of guipure binding transposed conductor, the guipure that insulate is wrapped, at last again in insulation guipure transposed conductor product line bottom, the i.e. high temperature resistant NOMEX(Nomex (Nomex nylon) of cushioning one deck again in the outside, bottom surface of Dan Nisong paper) paper is formed.
The utility model adopts single face to have the Nomex(Nomex (Nomex nylon) of viscose glue) heat-resisting paper, sticky surface is pasted mutually with the lead guipure when being beneficial to use, guarantees that paper slip is not shifted.
The utility model design, make special-purposely, make the inboard Dan Nisong paper slip and the Nomex(Nomex (Nomex nylon) in the outside with spacing paper feeding frock) paper slip twines when transposed conductor is made that the process of guipure is forward and backward carries out paper feeding, spacing.Nurse is manually assisted in paster work, through repeatedly achieving success after the experiment.
The beneficial effects of the utility model are:
Transposed conductor of the present utility model bottom surface is carried out electric insulation between can be with each lead after the transformer coli winding moulding and is separated with heat energy and isolate.Because of being in the inside of winding, winding temperature rise is high with respect to the surface that contacts with the transformer cooling fluid, and behind these two kinds of insulating papers of cushioning, electric property, the resistance to elevated temperatures of transformer are all effectively promoted.This lead is applied to the strong current transformer winding, when transformer operation produces big heat energy, guarantees that winding does not break down or reduction of service life because of being heated.This product is applied to the heat-resisting high temperature transformer of big electric current of domestic certain popularity transformer co-partnership company, and applicable cases is good.Can reduce ageing of insulation speed, improve transformer useful life greatly.
Description of drawings
Fig. 1 is a structural diagrams of the present utility model.
Number in the figure: 1 is bare copper flat wire, and 2 for the polyester acetal adds the compound varnished insulation layer of epoxy self-bonding, and 3 is polyester webs tape insulation layer, and 4 is individual layer Dan Nisong paper, and 5 is the high temperature resistant NOMEX(Nomex (Nomex nylon) of one-side band viscose glue) paper.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings below by example.
Embodiment 1: lead is by bare copper flat wire 1, compound varnished insulation layer 2, polyester webs tape insulation layer 3, Dan Nisong ply of paper 4 and Nomex (Nomex nylon) layer 5 are formed, all be coated with compound varnished insulation layer 2 outside the every bare copper flat wire 1, constitute enameling copper strap wire, many enameling copper strap wires are through the transposition of transposition equipment, be twisted into enamelled wire heart yearn bundle, enamelled wire heart yearn bundle bottom is pasted with Dan Nisong ply of paper 4, the enamelled wire heart yearn bundle that posts Dan Nisong ply of paper 4 is coated with polyester webs tape insulation layer 3, polyester webs tape insulation layer 3 external pasting have Nomex (Nomex nylon) layer 5, and Nomex (Nomex nylon) layer 5 is positioned at the loose ply of paper of red layer 4 bottoms.
The said structure transposed conductor is used for certain famous transformer co-partnership company, and its wire gauge is that 1.55mm * 7.45mm * 21(is solid conductor thickness a * width b * lead radical n in parallel).The solid conductor yield strength is δ 0.2 〉=170N/mm
