Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment of switchgear of the invention, as shown in Figure 1 to Figure 3, switchgear include isolation ground connection combination
Switch A, isolation ground connection stacked switch A includes isolating switch mechanism and earthing switch mechanism.Earthing switch mechanism includes that ground connection is opened
Close moved end touch base 1, earthing switch static side touch base component 2 and earthing switch feeler lever 3.Earthing switch static side touch base component 2 includes connecing
Ground switch static side touch base 21 and the earthing switch static side touch base shielding case 22 for being sleeved on 21 outside of earthing switch static side touch base.Ground connection
Switch static side touch base 21 is cylindricality, is internally provided with the inner hole being inserted into for earthing switch feeler lever 3, and the inner wall of inner hole, which is equipped with, to be used
In conductive spring touch finger 25.Earthing switch static side touch base shielding case 22 is tubular construction, and the front end of tubular construction is the knot that closes up
Structure, rear end, which is equipped with, is used for mounting hole, and earthing switch static side touch base shielding case 22 is fixed on by corresponding bolt after passing through mounting hole
On the touch base of disconnecting switch moved end.Striking circle 23 is cirque structure, and the inner hole of the circular ring structure is connected to the inner hole of touch base, is used
In for ground connection feeler lever insertion.23 rear end of striking circle striking ring platform 231 with outward extension keeps its overall structure pre-small post-large
Step Shaft shape structure, the front end of striking circle inner hole is equipped with the tapered surface 232 for guidance.The force transmission element 24 of isolation material is ring
Shape structure, the size of inner hole is in the same size with the periphery of striking circle 23, and such force transmission element 24, which can cover, is attached to striking circle
In the path section of 23 front ends, 24 rear end of force transmission element step 241 with outward extension, the shape and earthing switch of step 241 be quiet
221 shape of closing-in structure of end 22 front end of touch base shielding case is just adapted to, so that closing-in structure 221 can be fastened on step 241
On.
After the assembly in place of earthing switch static side touch base component 2, earthing switch static side touch base 21 is bolted on isolation
It switchs on moved end touch base 7, earthing switch static side touch base shielding case 22 is fixed on disconnecting switch moved end by the mounting hole of its rear end
On touch base, force transmission element 24 is pressed into outside striking circle 23 by earthing switch static side touch base shielding case 22 by the closing-in structure of its front end
In land on week, cooperate the front end face block of striking circle 23 and earthing switch static side touch base, realizes the fixation of striking circle, this
When force transmission element 24 constitute shielding case closing-in structure the force transmission element between striking circle, after being installed in place, the receipts of shielding case 22
The front end face of mouth structure 221 is concordant with the front end face of the front end face of force transmission element and striking circle, makes compact-sized at this.It is logical in this way
It crosses shielding case the installation of striking circle can be realized and fix, avoid in addition setting fixed structure and fixing piece to fix striking circle,
Reduce the number of parts of touch base component, structure is simple, and cost also accordingly reduces.In use, earthing switch feeler lever exists
During touch base adaptation plugs together, first close to striking circle, if you occur electric discharge phenomena, electric arc just generate feeler lever and striking circle it
Between, avoid fingertip on touch base is made its electric conductivity be affected by the ablation of electric arc.
In the above embodiment of the invention, between the closing-in structure and striking circle of earthing switch static side touch base shielding case
It is to make earthing switch static side touch base shielding case and striking circle insulated contact that force transmission element, which is arranged, and such electric current would not be from ground connection
It circulates on switch static side touch base shielding case, the fever deformation of earthing switch static side touch base shielding case is avoided, it is, of course, also possible to connecing
Insulating coating is set at the closing in of ground switch static side touch base shielding case or is set on the position that striking circle is contacted with closing-in structure
Insulating coating is set so that mutually insulated between earthing switch static side touch base shielding case and striking circle, at this time the closing-in structure of shielding case
Striking circle is directly fitted in the hole of the jack of touch base along upper；It sets striking circle on the striking circle of circular ring shape, makes striking circle
Structure is simple, easy to process, and the shape of striking circle can be just adapted to the end face of touch base, keep touch base modular construction tight
It gathers, volume reduces；Earthing switch static side touch base shielding case is fastened on the step of force transmission element by the closing-in structure of its front end, is passed
Power part is set on the periphery of striking circle and cooperates with striking ring platform block, processes land on force transmission element and striking circle in this way
, keep component structural simple, it is easy to process, it is, of course, also possible to which annular groove is arranged on the rear end face of force transmission element, opened in ground connection
It closes and turning edge to rear side is set at the closing in of static side touch base shielding case, this, which turns edge, when installation is buckled in annular groove, this to turn edge and ring
The fit structure of slot also can be realized the installation of earthing switch static side touch base shielding case and force transmission element, can also be after striking circle
Annular groove is set on end face, sets force transmission element to also to can be realized force transmission element in this way with the annulus of the annular groove shape adaptation at this time
Being fixed to each other between striking circle；The tapered surface of the inner hole front end of striking circle can also be rounding corner structure.In common ground connection
It can also be using the structure of the earthing switch static side touch base component in above-described embodiment in switch.
The embodiment of touch base component of the invention, the touch base component are opened with the ground connection in the embodiment of above-mentioned switchgear
