Abstract

The utility model discloses a major insulation structure of a soft angle ring, which comprises an iron core, a high-voltage coil, a low-voltage coil and a soft angle ring, wherein the soft angle ring is made from two layers of crepe insulating paper with 0.8 mm in thickness and is directly added between the high-voltage coil and the low-voltage coil during coil winding, a piece of common insulating paper with height consistent to the high-voltage coil and the low-voltage coil is simultaneously added, so that the major insulation structure with the total thickness of 2.6 mm is formed. After the major structure is adopted, the insulating strength of the entire transformer is increased, the volume is obviously reduced, the material cost is reduced by about 4%, so that the coil winding process is simplified, and the production efficiency is greatly increased.

Description

A kind of soft corner-ring Main Insulation Structure of Electric
Technical field
The utility model relates to field transformer, particularly a kind of soft corner-ring Main Insulation Structure of Electric.
Background technology
Main insulating structure and structure are one of technology of transformer most critical between the high and low pressure coil.Wherein, the distance of main insulation and structure want to guarantee that the dielectric strength of height coil is not breakdown under various operating modes.Simultaneously, the large young pathbreaker of the distance of main insulation directly affects material cost and the loss of transformer.For a long time, reduce main insulating structure is the technical essential that transformer industry lays siege to always.
As shown in Figure 1, the distance of traditional 10kv distribution transformer main insulation is about 9mm, adopting many thickness on the structure is 9mm, and the stay of width 7mm is intermittently fixed high-voltage coil and low-voltage coil along circumference, and the while is full of transformer oil and forms Main Insulation Structure of Electric in main insulation.This connecing strand mainly is the voltage breakdown path that has guaranteed sufficient length.
Yet traditional Main Insulation Structure of Electric is so that the volume of whole transformer becomes large, and material cost also increases, and comparatively time-consuming when making, and has greatly affected the raising of performance and efficient.
The utility model content
For the problem that above-mentioned traditional Main Insulation Structure of Electric exists, the purpose of this utility model is: propose a kind of soft corner-ring Main Insulation Structure of Electric, to address the above problem.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of soft corner-ring Main Insulation Structure of Electric comprises: iron core, high-tension coil, low-voltage coil and soft corner-ring;
Described soft corner-ring adopts two-layer insulating crepe paper, directly is added on when coil winding between the high and low pressure coil, attaches simultaneously the common insulating paper consistent with the high and low pressure coil height;
The thickness of described insulating crepe paper is 0.8mm.
Described two-layer insulating crepe paper and described common insulating paper consist of the main insulation that gross thickness reaches 2.6mm.
Do not place stay between the described high and low pressure coil, do not keep the space.
Described two-layer insulating crepe paper length exceeds the coil axial height, and the raised area equals the width of cloth of high-tension coil to thickness.
After the bending of described insulating crepe paper the high-tension coil end is covered in, form continuous insulator, thereby effectively guaranteed to reduce the voltage breakdown path behind the main insulating structure.
The beneficial effects of the utility model are: adopt the utility model so that the dielectric strength of transformer integral body improves, volume obviously reduces, and material cost reduced about 4%, makes the coil winding work simplification, has greatly improved the efficient of producing.
Description of drawings
Fig. 1 is traditional 10kv distribution transformer Main Insulation Structure of Electric schematic diagram;
Fig. 2 is the utility model Main Insulation Structure of Electric schematic diagram.
Wherein, 1-iron core, 2-high-tension coil, 3-low-voltage coil, 4-voltage breakdown path, 5-main insulation thickness, 6-soft corner-ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 2, a kind of soft corner-ring Main Insulation Structure of Electric comprises: iron core 1, high-tension coil 2, low-voltage coil 3 and soft corner-ring 6;
It is the 0.8mm insulating crepe paper that described soft corner-ring 6 adopts two layers of thickness, when coil winding, directly be added between the high and low pressure coil 2,3, attach simultaneously the common insulating paper highly consistent with high and low pressure coil 2,3, make it to form the main insulation 5 that gross thickness is 2.6mm;
Do not place stay between the described high and low pressure coil 2,3, do not keep space, simple process.
Described two-layer insulating crepe paper length exceeds the coil axial height, and the raised area equals the width of cloth of high-tension coil 2 to thickness, because crimped paper bends easily, can will after the described insulating crepe paper bending high-tension coil 2 end cover be lived, form continuous insulator, thereby effectively guaranteed to reduce the voltage breakdown path 4 behind the main insulating structure.
The above-described preferred embodiment of utilizing describes the utility model in detail, and unrestricted scope of the present utility model.Those skilled in the art can make trickle change and adjustment by after reading the utility model, and the main idea of the present utility model of will can yet be regarded as place does not also break away from spirit and scope of the present utility model.
