Embodiment
See also Fig. 1, shown in 2 or 3; The present invention includes operating mechanism 1 and three vacuum interrupters 2; It is characterized in that: described operating mechanism 1 comprises on support 11 supports 11 and is fixed with three pairs of sliding support plates 12; Sliding support plate 12 respectively is provided with up and down parallel chute 13,14, be rotationally connected the respectively insulated tension pole 21 of three vacuum interrupters 2 of an end of isolating switch slip connecting lever 3, the other end by spacer pin 4 rotational fixation on isolating switch pull bar 5; Spacer pin 4 drops in the upper hopper chute 13 of sliding support plate 12; Be rotationally connected the respectively insulated tension pole 21 of three vacuum interrupters 2 of one end of earthed switch slip connecting lever 6, the other end is sold 7 rotational fixation on earthed switch pull bar 8 by ground connection, and ground connection pin 7 drops in the gliding groove 14 of sliding support plate 12; Isolating switch slip connecting lever 3 is provided with chute 31,61 with corresponding respectively spacer pin 4 of earthed switch slip connecting lever 6 other ends and ground connection pin 7; Also be fixed with on the support 11 and isolate connecting lever support 15, ground connection connecting lever support 16, isolate connecting lever 9 one ends and be rotatably connected on the isolation connecting lever support 15, the other end is rotationally connected on the isolating switch pull bar 5; Ground connection connecting lever 10 1 ends are rotatably connected on the ground connection connecting lever support 16, and the other end is rotationally connected on the earthed switch slip connecting lever 6.
It is the distance of opening of vacuum interrupter 2 isolating switches that described isolation connecting lever 9 drives isolating switch pull bar 5 mobile stroke in upper hopper chute 13, and it is the distance of opening of vacuum interrupter 2 earthed switches that ground connection connecting lever 10 drives earthed switch slip connecting levers 6 mobile stroke in upper hopper chute 14.
When described isolating switch slip connecting lever 3 was grounded switch lever 8 drive actions at earthed switch slip connecting lever 6, spacer pin 4 slided in chute 31, does not drive isolating switch pull bar 5; When described earthed switch slip connecting lever 6 drove action at isolating switch slip connecting lever 3 isolated pass pull bars 5, spacer pin 4 slided in chute 61, does not drive earthed switch pull bar 8.
Described isolation connecting lever 9 drives rotation by isolating power shaft 91; Drive isolating switch pull bar 5; The insulated tension pole 21, three that passes to three vacuum interrupters 2 by isolating switch pull bar 5 drive isolating switch slip connecting levers 3 links, and drives the divide-shut brake action of isolating switch.
Described ground connection connecting lever 10 is driven by ground connection power shaft 101 and rotates; Drive earthed switch pull bar 8; The insulated tension pole 21, three that passes to three vacuum interrupters 2 by earthed switch pull bar 8 drive earthed switch slip connecting levers 6 links, and drives the divide-shut brake action of earthed switch.
Shown in Fig. 1 or 2; When being rotated counterclockwise isolation power shaft 91, isolating power shaft 91 drive isolation connecting levers 9 and be rotated counterclockwise, thereby drive isolating switch pull bar 5 to left movement; And through spacer pin 4 promote isolating switch slip connecting levers 3 in the upper hopper chute 13 of sliding support plate 11 to left movement; Thereby promote the insulated tension pole 21 interior isolation switch contact length of spring compressed of vacuum interrupter 2, and promote insulating contacts motion in the vacuum interrupter 2, isolating switch closes a floodgate.When insulated tension pole 21 isolated pass slip connecting levers 3 promote; Earthed switch slip connecting lever 6 is grounded pin 7 and drives, because ground connection slip connecting lever 6 other ends are provided with chute 14, this moment is when earthed switch slip connecting lever 6 is stressed; Just motion in the chute 14 of earthed switch slip connecting lever 6 of ground connection pin 7; Because this chute 14 guarantees that earthed switch pull bar 8 is motionless, thus isolating switch slip connecting lever 3 when motion, 7 of spacer pins move the chute 14 of earthed switch slip connecting lever 8 in; And can in the gliding groove 14 of sliding support plate 11, not move; Just can not apply the effect of any power, so when isolating switch moves, can not produce any involving to earthed switch to ground connection switch lever 10 and ground connection power shaft 101 yet.The action of earthed switch is identical with isolating switch, and just one of active force to insulated tension pole is a pulling force, and one is thrust, and the action step of earthed switch is just given unnecessary details at this no longer one by one.
More than describing is to explanation of the present invention, is not to qualification of the present invention, and institute of the present invention restricted portion is referring to claim, and under the situation of spirit of the present invention, the present invention can do any type of modification.
The above; Only being preferred embodiment of the present invention, is not that the present invention is done any restriction, every according to the present invention technical spirit to any simple modification that above embodiment did; Change and equivalent structure change, and all still belong in the protection range of technical scheme of the present invention.
