Abstract
The invention discloses a high-voltage gas immersed termination mounting and positioning structure. A pluggable high-voltage gas immersed termination (GIS) comprises a high-voltage cable, an epoxy sleeve, an inner insulator and a plugging and unplugging mechanism. The structure is characterized in that: three groups of sliding pins and springs are radially uniformly distributed on the end part of a moving contact in the plugging and unplugging mechanism; three sliding chutes are axially formed on the inner hole sidewall of an upper electrode of the epoxy sleeve; the roots of the three sliding chutes are radially provided with a positioning groove respectively; and the three groups of sliding pins and springs of the end part of the moving contact are assembled, disassembled, moved and positioned by the three corresponding sliding chutes and the corresponding positioning grooves. The structure realizes the function of plugging and unplugging the cable relative to the epoxy sleeve, improves the positioning accuracy of the cable, simplifies a mounting process and improves the construction efficiency.
Description
Technical field
The present invention relates to the mounting structure of a kind of gas-insulated terminal (GIS terminal), particularly disclose a kind of installation and positioning structure of gases at high pressure insulation terminal, be applicable to the installing and locating of 110kV and above GIS terminal.
Background technology
Gas-insulated terminal (gas immersed termination is called for short the GIS terminal), being installed in gas-insulated sealing switch equipment (GIS) inner is the cable termination of the gas-insulated part of external insulation with sulphur hexafluoride (SF6) gas.High pressure GIS terminal mainly is made up of high-tension cable, epoxy bushing, interior insulation system, mainly is divided into common GIS terminal and plug-in GIS terminal by mounting means.
Common GIS terminal can only be with after the whole terminal installation, and sealing is installed in the whole then GIS of the insertion cylindrical shell.
Plug-in GIS terminal can realize earlier epoxy bushing and GIS cylindrical shell sealing installation, even epoxy bushing can be in the preceding installation of dispatching from the factory of GIS switch, like this, need not to open again the GIS cylindrical shell in the erecting bed, reduce the possibility of polluting GIS inside, and reduce a large amount of vacuum processing time.
Present plug-in GIS terminal generally adopts moving contact, as the watchband fingertip, realizes that the plug on electric connects.The mechanical fixation but cable and epoxy bushing still are unrealized can only be to rely on the cable anchor ear of terminal afterbody to realize the axial restraint (see figure 1).This fixing and unreliable, in case the inner generation of cable axial displacement, the then inevitable occurrence positions of the interior insulation of terminal changes, and the performance of terminal can't guarantee.The cable location of this structure is that the exposed parts length L determines that cable is decided to be accurate inadequately after inserting epoxy bushing by control cable, and installation process and fixed form are also comparatively loaded down with trivial details.
Summary of the invention
The objective of the invention is to address the deficiencies of the prior art, a kind of installation and positioning structure of gases at high pressure insulation terminal is disclosed, it is a kind of installation and positioning structure of fast simple high pressure GIS terminal, realized the plug function of cable with respect to epoxy bushing, improve the accuracy of cable location, simplify installation process, improve efficiency of construction.
The present invention is achieved in that a kind of installation and positioning structure of gases at high pressure insulation terminal, and plug-in gases at high pressure insulation terminals (GIS terminal) comprise high-tension cable, epoxy bushing, interior insulation and push-pull structure; The top electrode of epoxy bushing is provided with endoporus, the endoporus of described top electrode is a blind hole, moving contact cooperates in the endoporus of described top electrode, moving contact and outlet bar are connected as a single entity, the outlet bar adopts mechanical crimping to be connected with the high-tension cable core, the structure of this part of outlet bar is the barrel shell structure, it is characterized in that: described push-pull structure is for to be provided with 3 groups of sliding pins and spring at moving contact end radial equipartition, be axially arranged with 3 chutes at described top electrode endoporus sidewall, root at described 3 chutes radially is provided with location notch, and 3 pairs of sliding pins of moving contact end and spring are respectively by realizing mounting or dismounting running fix in corresponding 3 chutes and the location notch.The radial angle of 3 chutes on the endoporus sidewall of 3 groups of sliding pins of described moving contact end and spring radial angle and top electrode is identical.
The invention has the beneficial effects as follows: realized the plug function of cable with respect to epoxy bushing, make the location of cable more accurate, also guaranteed the long-term reliability of cable location simultaneously, improve site operation efficient, save the cable anchor ear structure of terminal afterbody, make product more succinct attractive in appearance.

Embodiment
With reference to the accompanying drawings 1,2 and 3, a kind of installation and positioning structure of gases at high pressure insulation terminal, plug-in gases at high pressure insulation terminals (GIS terminal) comprise high-tension cable 10, GIS cylindrical shell 8, epoxy bushing 7, interior insulation and push-pull structure.The top electrode 4 of epoxy bushing 7 is provided with endoporus, the endoporus of top electrode 4 is a blind hole, and moving contact 6 cooperates in the endoporus of top electrode 4, and moving contact 6 is connected as a single entity with outlet bar 3, outlet bar 3 adopts mechanical crimping to be connected with high-tension cable core 9, and the structure of outlet bar 3 these parts is the barrel shell structure.Push-pull structure is for to install 3 groups of sliding pins and spring 1 in advance at moving contact 6 end radial equipartitions, top electrode 4 endoporus side-wall shafts to processing 3 chutes 2, root at 3 chutes 2 radially is provided with location notch 5, and 3 pairs of sliding pins of moving contact 6 ends and spring 1 are respectively by realizing mounting or dismounting running fix in corresponding 3 chutes 2 and the location notch 5.The radial angle of 3 chutes 2 on the endoporus sidewall of 3 groups of sliding pins of moving contact 6 ends and spring radial angle and top electrode 4 is identical.
When the 9 location crimping of outlet bar 3 and core, with 3 groups of sliding pins on the outlet bar 3 and 3 chutes 2 on the relative top electrode 4 of the spring relative angle α that staggers.Insert in epoxy bushings 7 processes at cable 10,3 groups of sliding pins on the outlet bar 3 and spring are radially stepped down along with the effect of the variation in top electrode 4 endoporus apertures and spring produces and are resetted, and finally slip into and realize the cable location in the location notch 5 set on top electrode 4 endoporus.
When product needed is dismantled, at first remove GIS cylindrical shell 8, unclamp connecting of epoxy bushing 7 and interior insulation, then with epoxy bushing 7 relative cable 10 rotations one angle [alpha], make 3 groups of sliding pins and spring on the outlet bar 3 of top electrode 4 interior 3 chutes and cable 10 corresponding, remove epoxy bushing 7, realization epoxy bushing 7 separates with cable 10.Because this structure adopts the location notch location, makes the location between cable and the epoxy bushing more accurate, convenient, reliable.
