Abstract
The utility model discloses a kind of loop construction improving anti-short circuit capability, include high and low pressure coil, high-tension coil is centered around the outside of low-voltage coil, the interior edge of high-tension coil is passed through even to be arranged with multilayer glue dispensing paper, is provided with stay curtain by bonding between the interior edge of multilayer glue dispensing paper and the outer of low-voltage coil.This utility model makes corrugated board into stay curtain, will batten or cardboard lath be bonded on a gummed paper, the deep equality of thickness and corrugated sheet；Adopt multilayer glue dispensing paper to replace cardboard, multilamellar is even around making thickness equal with base board simultaneously；The part contacting with point gummed paper when device body is dried will stick together, and make high-low pressure form an entirety, the changing of the relative positions will not occur each other, improve the anti-short circuit capability of distribution transformer.
Description
Technical field
This utility model is related to the coil field of distribution transformer, specifically a kind of coil knot improving anti-short circuit capability
Structure.
Background technology
Distribution transformer, in short circuit, bears radial short-circuit force and axial short-circuit force simultaneously, not only has phase between high-low pressure
Repulsive interaction, and have upper and lower changing of the relative positions power.In prior art, it is to be separated by corrugated board and cardboard between high-low pressure, because Concha Arcae
The elasticity of cardboard makes to be easy to sliding transfer between high-low pressure, more loosening between high-low pressure after being particularly dried, and causes
When transformator is subject to short-circuit force, the high-voltage coil and low-voltage coil changing of the relative positions is bigger, easily occurs damaging.
Utility model content
The purpose of this utility model is to provide a kind of loop construction improving anti-short circuit capability, to solve high in prior art
The problem of the changing of the relative positions between low pressure, to improve the anti-short circuit capability of distribution transformer.
The technical solution of the utility model is as follows：
A kind of loop construction improving anti-short circuit capability, includes high and low pressure coil, described high-tension coil is centered around institute
State the outside of low-voltage coil it is characterised in that：The interior edge of described high-tension coil is passed through even to be arranged with multilayer glue dispensing paper, described multilamellar
It is provided with stay curtain by bonding between the interior edge of point gummed paper and the outer of described low-voltage coil.
The loop construction of described raising anti-short circuit capability it is characterised in that：Described stay curtain is described many for being bonded in
The batten on edge or hardboard in layer point gummed paper.
The beneficial effects of the utility model：
This utility model makes corrugated board into stay curtain, will batten or cardboard lath be bonded on a gummed paper, thickness with
The deep equality of corrugated sheet；Adopt multilayer glue dispensing paper to replace cardboard, multilamellar is even around making thickness equal with base board simultaneously；In device body
The part contacting with point gummed paper when being dried will stick together, and make high-low pressure form an entirety, the changing of the relative positions will not occur each other,
Improve the anti-short circuit capability of distribution transformer.
Brief description
Fig. 1 is this utility model structural representation.
Specific embodiment
Referring to Fig. 1, a kind of loop construction of raising anti-short circuit capability, include high and low pressure coil 1,4, high-tension coil 1 encloses
It is wound on the outside of low-voltage coil 4, the interior edge of high-tension coil 1 is passed through even to be arranged with multilayer glue dispensing paper 2, the interior edge of multilayer glue dispensing paper 2
It is provided with stay curtain 3 by bonding between the outer of low-voltage coil 4.
In this utility model, stay curtain 3 is to be bonded in the batten on edge or hardboard in multilayer glue dispensing paper 2.
