Description
Technical field
The present invention relates to a kind of electric cable fitting, particularly a kind of solid insulated busbar syndeton be connected with user side for switchgear.
Background technology
In circuit on power system, middle pressure sulphur hexafluoride (SF6) gas-insulated switch is conventional a kind of switchgear.At present, the electrical connection of middle pressure sulphur hexafluoride (SF6) gas-insulated switch and other electric equipments and user side is all select power cable and annex thereof to realize as the connected mode of line substantially.Conventional electric cable accessories has inner cone plugging formula terminal and separable connector these two kinds, but these connected modes have the following disadvantages: existing every bar cable line (maximum cross-section 630mm
2) rated current of 1250A can only be met, when user requires the loop of big current (as 2000A or 2500A), just must adopt paired cable circuit, so just increase complexity and the overall dimension of switchgear, also to install and use a set of cable and annex thereof more simultaneously, cost increase is very large, limits using and developing of middle pressure sulphur hexafluoride (SF6) this class switchgear of gas-insulated switch.
In the prior art, the syndeton for cabinet splicing between switch cubicle and switch cubicle, factor that is different due to purposes, that consider is different, applicable situation is different, can not be applied directly to the connection of switch cubicle and user side.
Summary of the invention
The object of the present invention is to provide a kind of solid insulated busbar syndeton be connected with user side for switchgear, this syndeton compact and reasonable, simple installation, use reliable, all insulation, non-maintaining, the rated current of middle pressure sulphur hexafluoride (SF6) gas-insulated switchgear can be improved more than 1 times, big current loop can be directly used in and not need to change switchgear, installing space and the complete machine cost of switchgear can be saved simultaneously significantly.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: a kind of solid insulated busbar syndeton be connected with user side for switchgear, insert in the air chamber of switch cubicle, be electrically connected with the auxiliary equipment in air chamber, it is characterized in that, be made up of solid insulated busbar and the bus plug being set in solid insulated busbar outside, bus plug is stretched out at solid insulated busbar two ends; Solid insulated busbar is provided with outer conducting layer one, and bus plug is provided with outer conducting layer two, is electrically connected and ground connection between outer conducting layer one with outer conducting layer two.
According to as above scheme, solid insulated busbar is inserted in bus plug or bus plug is sleeved on solid insulated busbar and just can be assembled into solid insulated busbar syndeton outward, then insert in air chamber, be electrically connected with the auxiliary equipment in corresponding air chamber and fix, connect user side with the other end of solid insulated busbar, finally can realize the electrical connection of switchgear and user side.Even if also there is device or the equipment of voltage transitions between switchgear and user side, this solid insulated busbar syndeton is applicable equally.
In particular, described solid insulated busbar is made up of copper pipe and the solid insulating layer being coated on copper pipe outside, is realized being electrically connected by copper pipe and the auxiliary equipment in air chamber.
As preferably, described copper pipe refers to copper tube.
As preferably, the junction of the auxiliary equipment in described copper pipe and air chamber is provided with silver coating.
As a kind of design specifically, described bus plug is sleeve-shaped, the cavity in it and the profile of solid insulated busbar suitable, the inwall of bus plug and the contact position of solid insulated busbar are provided with air-gap screened cover.Bus plug can adopt insulating elastic material to make, and closely cooperates with solid insulated busbar.
Described solid insulated busbar is provided with the flange for being connected with air chamber; Described bus plug is positioned at above flange.Solid insulated busbar arranges mounting flange, can the connection of easy solid isolated bus syndeton and air chamber; And bus plug to be set on solid insulated busbar and to be positioned at the top of flange, flange can also play certain support and sealing function, killing three birds with one stone.
Described flange refers to metal flange; Outer conducting layer one is arranged on solid insulated busbar and is positioned at part outside air chamber, and outer conducting layer two is only arranged on one end of bus plug and flange contact, is electrically connected between outer conducting layer one with outer conducting layer two by metal flange.
Described flange is provided with seal groove, is conducive to enhanced leaktightness effect.
Design principle of the present invention is such: adopt said structure for realizing the connection of switch cubicle and user side, solid insulated busbar instead of power cable, bus plug instead of cable termination to be equivalent to use, and have accordingly been shape, structural design and optimization, consider through-current capability and the factors such as facility be installed and draw.Because the conductor cross-sectional flow area in solid insulated busbar in the design is more much larger than the sectional area of power cable, therefore the through-current capability of middle pressure sulphur hexafluoride (SF6) gas-insulated switchgear can be improved more than 1 times; Simultaneously because solid insulated busbar surface is provided with outer conducting layer, so accomplished all insulation, non-maintaining, barrier propterty is high.
The present invention possesses following outstanding advantages and effect relative to prior art:
1, solid insulated busbar syndeton of the present invention, propose for the deficiency of existing power cable connected mode, by using this syndeton, do not need the basic structure and the overall dimension that change switchgear, low cost of manufacture, effective, be the improved procedure best embodying economy, significantly can save installing space and the complete machine cost of switchgear;
2, the solid insulated busbar syndeton of the application of the invention, improves 1 times by the rated current of middle pressure sulphur hexafluoride (SF6) gas-insulated switchgear, can be directly used in big current loop;
3, solid insulated busbar syndeton of the present invention, all insulation, non-maintaining, barrier propterty is high.
