Interior connecting lever 5 is arranged in housing 1 by power transmission shaft 6, power transmission shaft 6 is by the transmission of outside transmission mechanism (not shown), in the present embodiment, for making interior connecting lever 5 simple in structure and easy for installation, interior connecting lever 5 is designed to " V " font, and its both ends arrange respectively draw-in groove 51, as shown in Figure 1, at earthed switch 3 and isolating switch 4, under off-state, ES trundle 33 and DS trundle 43 snap in respectively in the draw-in groove 51 at interior connecting lever 5 both ends.
In the present embodiment, draw-in groove 51 is " U " type groove for cross section, and the both ends height of U-shaped groove is unequal and form introducing port.As shown in Figure 3, when interior connecting lever 5 forward (counterclockwise), DS trundle 43 snaps in draw-in groove 51 by introducing port, by rotating interior connecting lever 5, makes draw-in groove 51 extruding DS trundles 43, DS trundle 43 promotes 41 motions of isolation moving contact, makes to isolate moving contact 41 and connects with the quiet end 7 of isolation; As shown in Figure 5, when interior connecting lever 5 reversion (clockwise), ES trundle 33 snaps in another draw-in groove 51 by introducing port, by rotating interior connecting lever 5, makes draw-in groove 51 extruding ES trundles 33, ES trundle 33 promotes 41 motions of isolation moving contact, and the quiet end 8 of ground connection moving contact 31 and ground connection is connected.
In order to prevent in isolating switch 4 connection motion processes, the distance that interior connecting lever 5 drive ground connection moving contacts 31 move backward is excessive, causes the operation failure of three stations; The present invention arranges ES bumping post 21 and ES clamping stagnation device 22 on pedestal, ES bumping post 21 is positioned at ground connection moving contact 31 axial directions, ES clamping stagnation device 22 is positioned at ground connection moving contact 31 radial direction, under the earthed switch off-state, ground connection moving contact 31 arranges trundle 33 1 ends and is resisted against ES bumping post 21, ES bumping post 21 is positioned at ground connection moving contact 31 axial direction 1mm to 2mm to be located, and ES clamping stagnation device 22 is by ground connection moving contact 31 location.
ES clamping stagnation device 22 is comprised of outer cover 221, clamping stagnation pearl 223 and spring 222, and outer cover 221 is arranged on pedestal 2, and clamping stagnation pearl 223 is placed in outer cover 221, and protrudes from outer cover 221, and spring 222 1 ends are against clamping stagnation pearl 223, one ends against outer cover 221; Accordingly, groove 311 is set on ground connection moving contact 31, under ground connection moving contact 31 positioning states, clamping stagnation pearl 223 snaps in groove 311.
Simultaneously, in order to prevent that earthed switch 3 is in connecting motion process, it is excessive that interior connecting lever 5 drives isolation moving contact 41 move distance backward, causes the operation failure of three stations; The present invention arranges DS bumping post 23 and DS clamping stagnation device 24 on pedestal, DS bumping post 23 is positioned at isolation moving contact 41 axial directions, DS clamping stagnation device 24 is positioned at isolation moving contact 42 radial direction, under isolating switch 4 off-states, isolation moving contact 41 arranges trundle 43 1 ends and is resisted against DS bumping post 23, DS bumping post 23 is positioned at isolation moving contact 41 axial direction 1mm to 2mm to be located, and DS clamping stagnation device 24 will be isolated moving contact 41 location.
DS clamping stagnation device 24 is comprised of outer cover 241, clamping stagnation pearl 243 and spring 242, and outer cover 241 is arranged on pedestal 2, and clamping stagnation pearl 243 is placed in outer cover 241, and protrudes from outer cover 241, and spring 242 1 ends are against clamping stagnation pearl 243, one ends against outer cover 241; Accordingly, on isolation moving contact 41, groove 411 is set, under isolation moving contact 41 positioning states, clamping stagnation pearl 243 snaps in groove 411.
In the present embodiment, two draw-in grooves 51 are arranged on interior connecting lever 5, and accordingly, isolation moving contact 41 and ground connection moving contact 31 arrange respectively DS trundle 43 and ES trundle 33.Certainly, also ES trundle and DS trundle can be set respectively on interior connecting lever 5, accordingly, on ground connection moving contact 31 and isolation moving contact 41, draw-in groove is set respectively, the ES trundle inserts the draw-in groove transmission ground connection moving contact 31 on ground connection moving contact 31, or the DS trundle inserts the draw-in groove transmission isolation moving contact 41 on isolation moving contact 41.
In use, as shown in Figures 1 and 2, the present invention is arranged on three station positions of high voltage switchgear in the present invention, and now, earthed switch 3 and isolating switch 4, all in off-state, are initial condition.Trundle 43 on isolation moving contact 41 all is positioned in the draw-in groove 52 of interior connecting lever 5 with the trundle 33 on ground connection moving contact 31, due to outside transmission mechanism in actionless state, interior connecting lever 5 also remains static, the position of the fixing isolation moving contact 41 of the draw-in groove 51 of connecting lever 5 and ground connection moving contact 31 in utilizing.
As shown in Figures 3 and 4, when isolating switch 4 is positioned at on-position, earthed switch 3 and is positioned at open position, this is normal operating condition.Moved to the process of normal operating condition by initial condition: outside transmission mechanism (not shown) drives power transmission shaft 6, and then in driving, connecting lever 5 rotates counterclockwise; Trundle 43 on isolation moving contact 41 snaps in draw-in groove 51 by introducing port, and the rotation of interior connecting lever 5 will be isolated moving contact 41 toward extrapolation, makes isolating switch 4 connect; Simultaneously interior connecting lever 5 also drives ground connection moving contact 31 and moves backward, until ground connection moving contact 31 is blocked by ES clamping stagnation device 22, fixedly connects moving contact 31, and now the trundle 33 at ground connection moving contact 31 places is derived and the interior connecting lever 5 of disengaging by introducing port.
When tri-station isolating switch 4 disconnects, interior connecting lever 5 clockwise rotates, and drives isolation moving contact 41 and disconnects with the quiet end 7 of isolation, gets back to initial condition.
As shown in Figures 5 and 6, when isolating switch 4 is positioned at open position, earthed switch 3 and is positioned at on-position, this is the inspection earthing state.Moved to the process of inspection earthing state by initial condition: outside transmission mechanism (not shown) drives power transmission shaft 6, and then in driving, connecting lever 5 clockwise rotates; Trundle 33 on ground connection moving contact 31 snaps in the draw-in groove 51 of interior connecting lever 5, and interior connecting lever 5 rotates the past extrapolation of ground connection moving contact 31, makes earthed switch 3 connect; Simultaneously interior connecting lever 5 also drives isolation moving contact 4 and moves backward, until isolate moving contact 41, by DS clamping stagnation device 24, is blocked, fixing isolation moving contact 41, and the trundle 43 of now isolating moving contact 41 places breaks away from interior connecting lever 5 by the introducing port derivation.
When three station grounding switchs 3 disconnect, interior connecting lever 5 rotates counterclockwise, and drives ground connection moving contact 31 and disconnects with the quiet end 8 of ground connection, gets back to initial condition.
The relevant term positions such as " up, down, left, right, before and afters " of the present invention, just for convenience of description, not in order to limit the present invention.The foregoing is only one embodiment of the present of invention, not to the restriction of this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection range of this case.
