Abstract
The utility model provides a dry-transformer winding conducting wire which belongs to the technical field of winding conducting wires for high voltage electrical apparatuses. A glass fiber band is wound on the surface of a metal bare wire, the glass fiber band is a composite silane glass fiber band without alkali and wax, the metal bare wire is made of material such as copper, aluminum, etc., and the shape of the section of the metal bare wire is flat, elliptical, circular and rectangular. The utility model solves the problems existing in the prior art that the operation is complicated, the cost is high, and the insulating strength is poor.
Description
The utility model relates to High-Voltage Electrical Appliances winding conducting wire technical field, specifically a kind of dry-type transformer winding conducting wire.
At present, the lead of traditional fabrication dry-type transformer winding, be generally the double glass fiber enamelled wire, this line must turn to lead after organdy twines, paint-dipping drying is shaped then, because of double glass fiber enamelled wire characteristic institute extremely, when paint-dipping drying is shaped, be easy to the bubble of portion's generation within it, and cause reduction, the non-refractory, easily aging of its dielectric strength; Moreover above-mentioned PROCESS FOR TREATMENT is quite loaded down with trivial details, and the winding that dielectric strength is had relatively high expectations also need repeatedly twine, dipping lacquer is handled, and it has not only increased cost, but also does not guarantee dielectric strength, has brought many worries to every aspect thus.
The purpose of this utility model is for solving above-mentioned insufficient section, a kind of dry-type transformer winding conducting wire easy and simple to handle, with low cost is provided, with the winding of its coiling through vacuum epoxy resin after annotating, its dielectric strength is higher.
The technical solution of the utility model is by following realization: the surface of metal bare wire is wound with glass fiber tape.Said glass fiber tape is that compound silane alkali-free does not have the wax glass fiber tape.Said metal bare wire is material such as copper, aluminium, and its cross sectional shape is flat, ellipse, circle and rectangle.
Advantage of the present utility model: one, simple in structure, easy making, dielectric strength height, high temperature resistant, ageing-resistant; Two, reduce treatment process, reduced cost; Three, simple installation is time saving and energy saving.
Figure of description is the utility model structural representation.
The contrast accompanying drawing is described in detail the utility model below.
The utility model dry-type transformer winding conducting wire, the surface of metal bare wire 1 is wound with glass fiber tape 2.Said glass fiber tape 2 does not have the wax glass fiber tape for compound silane alkali-free.Said metal bare wire 1 is material such as copper, aluminium, and its cross sectional shape is flat, ellipse, circle and rectangle.During use, the utility model turned to dry-type transformer or electric current, voltage transformer or reactor winding after, be fixed in then in the mould, get final product to its casting epoxy resin by existing vacuum epoxy resin pouring technology.Compound silane alkali-free does not have the wax glass fiber tape and can combine with the higher epoxy resin of dielectric strength.
