(NJK801)；
The earthing block mounting base (NJK401~403) setting is described in the outside of conductor mounting base (NJK301~303)
Earthing block mounting base (NJK401~403) is for installing grounding copper bar；
Stiffener plate (NJK501) is designed between the conductor mounting base (NJK301~303)；
It is fixed bracket (NJK701~704) that operating mechanism control electronic box is provided on main casing (NJK101) control electronic box.
The stiffener plate (NJK501) is T-type.
Main casing (NJK101) the side side is plane setting, forms the mounting plane region of control electronic box.
The utility model has the advantages that: 1, this shell compact-sized, both artistic and practical, and dimensional footprint reduces
20% or so, volume/volume reduces 30% or so, weight saving 25% or so.
2, the volume of this shell is small, and SF6 solar term rate improves 15% or so, and leakage rate per year reaches 0.20% or less.
3, the operating mechanism of this shell is safe and reliable to operation, can manipulate with electronic manually, significantly improve GIS and open

Detailed description of the invention
The structural perspective of Fig. 1,2 existing earthing switch operating mechanism shells.
The structural perspective of the utility model earthing switch operating mechanism shell of Fig. 3,4,5.
The main shell structure figure of Fig. 6,7 the utility model earthing switch operating mechanism shells.
Specific embodiment
The utility model operating mechanism shell is described in further detail below in conjunction with attached drawing.
The perspective view of the utility model operating mechanism shell.The primary structure of the utility model operating mechanism shell includes:
Main casing NJK101, be open connecting flange NJK201, conductor mounting base NJK301~303, and earthing block mounting base NJK401~
403, stiffener plate NJK501, operating mechanism external connection interface NJK601, fixed bracket NJK701~704 of operating mechanism control cabinet,
Fixed pivot NJK801 inside operating mechanism.It is detailed in following embodiment.
To realize the miniaturization of GIS device, the technology growth requirement of compact, the utility model operating mechanism shell reduces
The diameter and height of main casing NJK101, volume reduce 35% or so, weight saving 20% or so, while body in order to prevent
Product reduces and influences the installation space of control electronic box, and the utility model is cut down the side of main casing NJK101, thus
Form the mounting plane region (dashed region in figure) of control electronic box.
Since the size of main casing NJK101 is significantly reduced, part-structure can not be designed and arranged, and after comprehensively considering, be taken
Disappeared air charging nozzle structure, observation window flange, earthing block mounting base, to realize the simplification of the utility model operating mechanism shell.
The earthing block mounting base that the utility model will be cancelled is transferred to the outer of 3 conductor mounting base NJK301~303
Side forms new earthing block mounting base NJK401~403, is used to install grounding copper bar, and wherein NJK401 is directly used, and
NJK402~403 is used as service ground block, enables when electric current is more than fixed require.
Since conductor mounting base NJK301~303 need to bear the dynamic impact of operating mechanism, once housing distortion occurs
It is excessive and cause electric fault then to will lead to operating mechanism kinematic error, therefore devises T-type reinforcement between 3 conductor mounting bases
Gusset, to guarantee the safe operation of operating mechanism.
Since the size of main casing NJK101 is significantly reduced, 4 upright post installation structures of existing shell control electronic box can not
Design arrangement, therefore 4 upright post installation structures are changed to 4 rack mounting structures, the i.e. fixed bracket of operating mechanism control electronic box
NJK701~704.
Further explanation is made to the utility model below: to realize technical solution used by the purpose of this utility model
It is: on the basis of existing earthing switch operating mechanism shell, the size of main body of main casing is reduced, is accounted for reducing space
With area, volume and volume are reduced, is laid the foundation for subsequent structural optimization；Since the reduction of main casing size influences whether control electricity
The installation space of case need to be cut down the side of main casing, to form the mounting plane region of control electronic box；Due to master
The size reduction of shell will lead to part-structure and can not be designed and arranged, need to cancel existing air charging nozzle structure, observation window flange,
The structures such as earthing block mounting base；The earthing block mounting base being cancelled is transferred to the outside of 3 conductor mounting bases, forms new connect
Plot mounting base；For the safe operation for guaranteeing operating mechanism, T-type stiffener plate is designed, between 3 conductor mounting bases to prevent
Housing distortion causes operating mechanism kinematic error excessive and causes electric fault；It is existing since the size of main casing is significantly reduced
Have shell control electronic box 4 upright post installation structures can not design arrangement, 4 rack mounting structures need to be changed to.
