Abstract

The utility model discloses an end ring of a transformer coil. The end ring consists of a first paperboard layer (1), a second paperboard layer (2), a third paperboard layer (3) and a fourth paperboard layer (4). The end ring designed and manufactured is high in mechanical strength and material-saving.

Description

A kind of transformer coil end circle
Technical field:
The utility model relates to a kind of end circle of transformer coil.
Background technology:
Transformer coil end circle in the past sticks up by the paper ring is a sheet by a sheet, what how thickly glue and open.This structure is neither saved material, and mechanical strength can only be calculated again generally.
Summary of the invention:
The purpose of this utility model provides a kind of transformer coil end circle.
The utility model is to adopt following technical scheme to realize its goal of the invention: a kind of transformer coil end circle is comprised of ground floor cardboard 1, second layer cardboard 2, triplex board 3, the 4th layer paperboard 4 couch boards; Second layer cardboard 2 sticks on by glue and connects on the ground floor cardboard 1, and triplex board 3 sticks on the second layer cardboard 2 by glue, and the 4th layer paperboard 4 sticks on the triplex board 3 by glue.
Owing to having adopted above technology the utility model to realize preferably its goal of the invention, a kind of transformer coil end coil structures mechanical strength that designs and produces is stronger, has saved material.

Embodiment:
Be described further below in conjunction with the accompanying drawing summary of the invention:
Embodiment 1:
By summary of the invention as can be known, a kind of transformer coil end circle is comprised of ground floor cardboard 1, second layer cardboard 2, triplex board 3, the 4th layer paperboard 4 couch boards; Second layer cardboard 2 sticks on by glue and connects on the ground floor cardboard 1, and triplex board 3 sticks on the second layer cardboard 2 by glue, and the 4th layer paperboard 4 sticks on the triplex board 3 by glue.
Ground floor cardboard 1 described in the utility model refers to: cardboard, and design is at innermost layer of the present utility model; Behind the hollow cylinder of cardboard coiled required thickness, being a kind of insulating material, is again the pressing plate of coil pressing.
Second layer cardboard 2 described in the utility model refers to: cardboard, and design is at the second layer of the present utility model; It is bonding around ground floor cardboard 1, is a kind of insulating material, is again the pressing plate of coil pressing.
Triplex board 3 described in the utility model refers to: cardboard, and design is at the 3rd layer of the present utility model; It is bonding around second layer cardboard 2, is a kind of insulating material, is again the pressing plate of coil pressing.
The 4th layer paperboard 4 described in the utility model refers to: cardboard, and design is at the 4th layer of the present utility model; It is bonding around triplex board 3, is a kind of insulating material, is again the pressing plate of coil pressing.
The material of ground floor cardboard 1 described in the utility model, second layer cardboard 2, triplex board 3, the 4th layer paperboard 4 is consistent.
Embodiment 2:
The utility model is for realizing the function of its cylindric coiling, and the both sides of every block of cardboard are joined together to form circular cylinder body, and its connector is cardboard interface 5; Its from inside to outside superimposed order be ground floor cardboard 1, second layer cardboard 2, triplex board 3, the 4th layer paperboard 4, the superimposed place between per two blocks of cardboards all is brushed with glue.
Cardboard interface 5 described in the utility model refers to: a position is the junction that every fast board rolls becomes its both sides behind the tubular; When every fast cardboard was bonding, cardboard interface 5 became dislocation bonding not at same position.
Glue described in the utility model refers to: super glue; Superimposed place between per two blocks of cardboards all is brushed with glue; Both strengthen its intensity, improved again its insulation property.
