Embodiment
The opening and closing induction current vacuum switch device that the utility model patent application proposes, consists of the operation panel of vacuum switch portion and vacuum switch subordinate portion, and vacuum switch is arranged in insulating sleeve.Because the technical characterstic of present techniques scheme does not relate to the vacuum switch portion structure on top, so only show composition mechanism and its action implementation procedure in operation panel.
Mounting panel in operation panel casing, actual is in the present embodiment two parallel installation clamping plate 18,19, two install rotational support between clamping plate 18,19 is provided with the moving connecting lever axle 4 of parallel control lever shaft 1, main shaft 3, driving shaft 2 and lock, the moving connecting lever 41 of lock on the moving connecting lever axle 4 of lock cut-offs and above pushes away closed switch control member as the lower contact feeler lever that drives vacuum switch is longitudinally drop-down, has mounted sluice separating spring 8 on it.The manipulatable end of control lever shaft 1 is drawn casing, and external control drives the clockwise or counterclockwise reciprocating rotating of control lever shaft 1.As shown in Figure 2, control lever shaft 1 clockwise revolution for separating brake actuating to, turning anticlockwise be combined floodgate actuating to.
The Knucle-gear 33 of main shaft 3 passes through sector 13 speed increasing ratio engaged transmission with control lever shaft 1, the moving connecting lever 31 of spring is fixedly installed on main shaft 3, combined floodgate spring 5 one end are mounted on the moving connecting lever 31 of spring, cam 30 on main shaft 3 closes a floodgate to turn to the sour jujube sheave 34 that is fixed on main shaft 3 through ratchet 32 and coordinates, and moving connecting lever 31 bearing of trends of the arc effect protrusion direction of described cam 30 and spring are reverse.
Acting on the mountain plate 21 of the moving connecting lever 4 of lock and the roller crank 20 coordinating with cam 33 is fixedly mounted on driving shaft 2.Between control lever shaft 1 and driving shaft 2, be provided with dogging portion, separating brake driving effect is played by dogging portion, it is by the chuck 10 being fixed on control lever shaft 1, the pendulum plate 22 that the driving shaft 2 of take is pivot, with be hinged on pendulum plate 22 1 sides, by spring-force driven dual, the pike pole 23 of hook end in chuck 10 surfaces formed jointly, chuck 10 is provided with separating brake to draw-in groove, pendulum plate 22 opposite sides are provided with the rigidity plectrum 222 with the spacing banking stop coordinating 221 of mounting panel 18 and effect Yushan Hill plate 21, because spring-force driven dual is by banking stop 221 and mounting panel 18 effects, make to put plate 22 in spacing place.Described mountain plate 21, a lateral edges with respect to the moving connecting lever 41 of lock on it is the arc-shaped guide rail 211 of the moving connecting lever 41 upper and lower reciprocally swingings of guiding lock, the top of mountain plate 21 is Katos 210 of the moving connecting lever of jacking lock top roller 40, and described arc-shaped guide rail 211 is from the paraxial point edge of root, to seamlessly transit the camber line rail at the axle point edge far away place to top.
Setting is that initial bit is carried out closing operation from gate-dividing state.As shown in Figure 1, in separating brake static state, the outer end of the moving connecting lever 31 of spring pulls the static initial bit in right-hand member because combined floodgate spring 5 resets to shrink, cam 30 on main shaft 3 has also been crossed the cooperation position with roller crank 20, the top roller of roller crank 20 drops down onto the root place of cam 30, and the top roller 40 of the moving connecting lever 41 of lock is the arc-shaped guide rail root in mountain plate 21 also.The realization of closing operation: as shown in Figure 2, control lever shaft 1 is driven by inverse time closing operation, the rotation of control lever shaft 1 makes separating brake that pike pole 23 slippages go out chuck 10 to draw-in groove, and make driving shaft 2 keep static, main shaft 3 rotates through Knucle-gear 33 and control lever shaft 1 sector engagement, the ratchet 32 of cam 30 is matched with main shaft sour jujube sheave 34, and start to return back to roller crank 22 belows downwards with main shaft 3, meanwhile, spring moves connecting lever 31 upper half stretching combined floodgate springs 5, for feed motion continues energy storage, until the rotation of control lever shaft 1 makes the moving connecting lever of spring 31 outer ends gradually when crossing combined floodgate spring 5 limit of stretch position, combined floodgate spring 5 retractions discharge the moment of energy storage, the moving connecting lever 31 of spring is pulled and makes the very fast continuation revolution of main shaft 3, cam 30 thereupon high velocity effect in roller crank 20, force very fast the erecting of mountain plate 21 of driving shaft 2, pendulum on the moving connecting lever 41 of very fast promotion lock, until top roller 40 cards of the moving connecting lever 41 of lock fall within Kato 210, realize vacuum switch portion feed motion.Now, top roller 40 centers of the moving connecting lever 41 of lock are crossed perpendicular to the vertical line of main shaft and are deviated from and are not more than 5 ° of angles, cross dead point, vertical line place, the stable "on" position that remains on.
The realization of sub-switching operation: combined floodgate static structure as shown in Figure 4 starts, control lever shaft 1 is handled by clockwise separating brake, it turns round a road and to draw-in groove, pulls pike pole 23 through the separating brake of chuck 10, the rigidity plectrum 222 of driving pendulum plate 22 is stirred mountain plate 21 and is clockwise rotated, top roller 40 at the moving connecting lever 41 of lock has just departed from Kato 210 in a flash, stressed in sluice separating spring 8, lock moves the very fast downslide of connecting lever 41, the lower contact feeler lever of drop-down vacuum switch portion, complete sub-switching operation, the top roller 200 of roller crank 20 also drops down onto the root of cam 30 thereupon again.
