Abstract
The utility model discloses a kind of three pillar supporting insulator of disc type for ultra-high/extra-high voltage GIS/GIL, including epoxy composite insulator, low-pressure side metallic shield ring, high-pressure side metallic shield and aluminium alloy bushing pipe.This structure need not inside low-pressure side epoxy composite insulating materials casting metal inserts, and supporting insulator can with pipe parent phase to slide, can discharge current-carrying tube mother temperature rise change produce deformation, realize electricity, heat, power distribution uniformity.The utility model can lift the safety and reliability of supporting insulator longtime running.
Description
Technical field
A kind of supporting insulator is the utility model is related to, more particularly to a kind of ultra-high/extra-high voltage gas-insulated switch that is used for fills
Put the three pillar supporting insulator of disc type of GIS/ gas-insulated transmission lines GIL.
Background technology
Ultra-high/extra-high voltage GIS/GIL supporting insulators mainly have disc insulator and pillar insulator at present.Disc insulator
It is required that installed in the flange or flange neighbouring position of GIS/GIL elementary cells, but when elementary cell is longer, it cannot be basic
Installation provides support and insulating effect inside unit.Pillar insulator may be mounted inside elementary cell, but in its low pressure
Metal insert is installed in end ring oxygen compound inslation body.The presence of metal insert in pillar insulator, can be in metal insert and ring
Electric field and stress field is caused to be concentrated at oxygen insulator interface, the accidental fine fisssure of meeting and shelf depreciation cause absolutely under the conditions of longtime running
Edge fails, and influences the safety and reliability of GIS/GIL longtime runnings.
Utility model content
The purpose of this utility model is to solve the problems, such as that existing design exists, there is provided one kind is used for ultra-high/extra-high voltage
The three pillar supporting insulator of disc type of GIS/GIL.
To reach above-mentioned purpose, the utility model adopts the following technical solution realizes：
A kind of three pillar supporting insulator of disc type for ultra-high/extra-high voltage GIS/GIL, including epoxy composite insulator are low
Side metallic shield ring is pressed, high-pressure side metallic shield and aluminium alloy bushing pipe, epoxy composite insulator are cast on aluminium alloy bushing pipe,
Aluminium alloy bushing pipe and pipe mother's sliding contact, high-pressure side metallic shield are installed on aluminium alloy bushing pipe, and epoxy insulator passes through low
Press side Boards wall.
Epoxy composite insulator outer ring is disc, and middle part is three trapezoidal, fan-shaped or other forms pillars, at center
It is integrated with the cast of aluminium alloy bushing pipe, plays a part of to support GIS/GIL current-carrying tubes mother and isolated tube mother and housing.
Epoxy composite insulator is cast on aluminium alloy bushing pipe, installation two or more polytetrafluoroethylene ring in aluminium alloy bushing pipe
Shape circle and pipe mother's sliding contact, aluminium alloy bushing pipe end installation metallic shield, epoxy composite insulator outer ring ring body pass through gold
Belong to shading ring to fix.
The utility model has the advantage of：Supporting insulator low-pressure side is fixed by metallic shield ring, eliminates low-pressure side
Metal insert, improve the safety and reliability of supporting insulator longtime running；Supporting insulator can be with pipe parent phase to cunning
It is dynamic, the deformation that pipe mother is produced due to current-carrying temperature rise can be discharged.

GIL flow tubes mother and the female effect with housing of isolated tube.
Three pillar supporting insulator low-pressure side of disc type by the metallic shield for being welded on a metal shell inner surface ring with
The symmetric figure metallic shield ring of removable installation is fixed.
Three pillar supporting insulator high-pressure side of disc type is by installing more than 2 polytetrafluoroethylene (PTFE) annular circles in aluminium alloy bushing pipe
With pipe mother's sliding contact, current-carrying tube mother opposite in aluminium alloy bushing pipe can slide.
The high-pressure side of three pillar supporting insulator of disc type is equipped with metallic shield, and installation site is in aluminium alloy bushing pipe end.
During installation, first three pillar supports insulative substring of disc type can be sleeved on current-carrying tube mother, then with removable metal screen
Ring is covered to be fixed on the metallic shield ring of metal shell inner surface welding；Also first three pillar supporting insulator of disc type can be consolidated
It is scheduled on the metallic shield ring of metal shell inner surface welding, is then passed through pipe mother.
