The utility model has the advantages of convenient installation, good consistency among phases of the load switch, higher strength, greater impulsive force and better resistance to bending.
Description
The utility model relates to a kind of indoor sulphur hexafluoride on-load switch insulating cover relevant with insulation property with the mounting means of load switch body.
The structure of existing its Threephase common-box of sulphur hexafluoride on-load switch adopts metal shell mostly, and outlet terminal needs to fix with insulator.The on-load switch of other kind also is the installation form that generally adopts by insulator, support, supplemental support, exist volume big, influence deficiency such as outward appearance.
The purpose of this utility model is the deficiency at above-mentioned existence, proposes a kind of brand-new insulation support and the indoor sulphur hexafluoride on-load switch insulating cover of sealing means.
Technical solution of the present utility model:
Form by upper and lower insulating cover 1,3, they become a sealed insulation cover after with bolted, wherein go up insulating cover 1 and become a whole one with fixed contact 6 cast, arc-chute 2 is fixedly mounted on the fixed contact 6, following insulating cover 3 pours into as a whole with outlet terminal 8, moving contact 4 is installed on the outlet terminal 8 and drives by connecting plate and connecting lever, insulating cover 3 front ends down operating mechanism is installed and fill, vent valve, and offer two watch windows; The rear portion is the design of pressure release passage formula, and the bottom is the umbrella skirt construction of vertical direction, and the adsorbent groove has been offered in inside, interior dress adsorbent, and earth terminal 5 usefulness screws directly are fastened on down the bottom of insulating cover 3;
The top arch of last insulating cover 1, the bottom rectangle, top, horizontal umbrella-skirt type structure is provided with flange around the bottom, and three-phase fixed contact and last insulating cover 1 pour into as a whole, and arc-chute 2 can be fixed together with elastic cylindrical pin and fixed contact;
The top rectangle of following insulating cover 3, the bottom arch, the vertical umbrella-skirt type structure in bottom is established flange around the top;
The front end of following insulating cover 3 can be installed operating mechanism, and can be connected with on-load switch main shaft 7 by axis hole, and the rear portion of following insulating cover 3 is the design of pressure release passage formula;
Three-phase lower wire end pours into as a whole with following insulating cover 3.
Advantage of the present utility model:
Guarantee the insulation creep distance all more than 240mm, easy for installation, each alternate high conformity of on-load switch, and improved the whole outer existing of on-load switch greatly, have better intensity, impulsive force and bending resistance.
Accompanying drawing 1 is a structural representation of the present utility model.The 7th, main shaft
Accompanying drawing 2,3 is respectively the structural representation of the upper and lower insulating cover of the utility model.
Further describe technical solution below in conjunction with accompanying drawing:
Form by upper and lower insulating cover 1,3, they become a sealed insulation cover after with bolted, wherein go up insulating cover 1 and become a whole one with fixed contact 6 cast, arc-chute 2 is fixedly mounted on the fixed contact 6, following insulating cover 3 pours into as a whole with outlet terminal 8, moving contact 4 is installed on the outlet terminal 8 and drives by connecting plate and connecting lever, insulating cover 3 front ends down operating mechanism is installed and fill, vent valve, and offer two watch windows; The rear portion is the design of pressure release passage formula; The bottom is the umbrella skirt construction of vertical direction; The adsorbent groove has been offered in inside, interior dress adsorbent, last insulating cover top is the umbrella skirt construction of horizontal direction, earth terminal 5 usefulness screws directly are fastened on down the bottom of insulating cover 3, and rely on earthy inserts to link to each other with the outside, pre-portion of insulating cover and bottom are the umbrella-skirt type structure, have guaranteed that the insulation creep distance is all more than 240mm.
This on-load switch adopts the structure of Threephase common-box, and three-phase fixed contact and insulating cover cast are as a whole.On-load switch is sealed in the upper and lower insulating cover, and fills SF6 gas as arc extinguishing and dielectric.Following insulating cover front end operating mechanism is installed and fill, vent valve, and offer two watch windows; The rear portion is the design of pressure release passage formula; The bottom is the umbrella skirt construction of vertical direction; The adsorbent groove has been offered in inside, interior dress adsorbent.Last insulating cover top is the umbrella skirt construction of horizontal direction.Insulating cover plays the installation supporting role of whole on-load switch, can play alternate, the insulating effect relatively of galvanic circle again.
Molding materials is an epoxy resin, and moulding process is the epoxy injection moulding process.
The top arch of last insulating cover 1, the bottom rectangle, top, horizontal umbrella-skirt type structure is provided with flange around the bottom, is convenient to install.
Three-phase fixed contact and last insulating cover as the galvanic circle pour into as a whole.
Arc-chute 2 can be fixed together with elastic cylindrical pin and fixed contact.
The top rectangle of following insulating cover 3, the bottom arch, the vertical umbrella-skirt type structure in bottom is established flange around the top, is convenient to install.
The front end of following insulating cover 3 can be installed operating mechanism, and can be connected with on-load switch main shaft 7 by axis hole; The front end of following insulating cover offer install fill, valve opening and two watch windows of vent valve.Inside offers the adsorbent groove, can place adsorbent.
The rear portion of following insulating cover 3 is the design of pressure release passage formula.
Three-phase lower wire end pours into as a whole with following insulating cover.
Earth terminal can be directly fixed on insulating cover inside with screw, and the required part of other on-load switch can be installed
Insulating cover adopts the epoxy injection forming technology, have higher dimensional accuracy, mechanical strength and good electrical properties than traditional vacuum pouring forming technology, the design of flange support makes insulating cover when on-load switch is worked, and has better intensity, impulsive force and bending resistance.
