Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
One has twice repetitive operation, has carried out the operating mechanism of isolating switch in the locking of three diverse locations.Utilize a unique main shaft 3, carry out twice repetitive operation, each rotation predetermined angular, come: isolating switch moving contact is positioned at closing position, it first rotates a predetermined angular, arrives open position, rotate a predetermined angular again and arrive earthing position, three station manipulations like this, and can lock in each position, thus avoid occurring causing the inaccurate consequence in position due to electric power, gravity or other external force.
As shown in figs 1-9, a kind of operating mechanism of tri-station isolating switch, comprise: with the panel 1 of handle hole 2, and to be positioned at inside panel 1 and the main shaft 3 that arrange coaxial with handle hole 2, overlap successively on the main shaft 3 handle hole 2 one end from main shaft 3 and have operating sleeve 4 and back-moving spring 5, back-moving spring 5 one end is fixed, the other end elastically-deformablely can prop up operating sleeve 4, the clamping block 6 that operating mechanism sets firmly is positioned at outside operating sleeve 4, clamping block 6 and operating sleeve 4 are respectively equipped with the first lock tooth 61 and the second lock tooth 41 of form fit engagement, operating sleeve 4 is after panel 1 inboard compression back-moving spring 5 certain distance, first lock tooth 61 and the second lock tooth 41 can depart from, the locking mutually respectively at least three positions that second lock tooth 41 can rotate relative to the first lock tooth 61.
Operating sleeve 4 is provided with waist-shaped hole, and waist-shaped hole axially extends along main shaft 3, and the bayonet lock 31 that main shaft 3 is provided with is fastened in waist-shaped hole 43 and play the guiding role.First lock tooth 61 of arcuate structure is looped around operating sleeve 4 periphery, two draw-in grooves 62 are provided with inside arcuate structure, the angle of two draw-in grooves 62 on arcuate structure is predetermined angular, second lock tooth 41 is three fixture blocks 42 be circumferentially with along operating sleeve 4, and the angle between middle fixture block 42 and the fixture block 42 on both sides is predetermined angular.Fixture block 42 can form fit snap in draw-in groove 62, after operating sleeve 4 is pressed certain distance inside panel 1, fixture block 42 departs from draw-in groove 62, and now operating sleeve 4 can drive main shaft 3 to rotate a predetermined angular.
It is predetermined angular that handle hole 2 is provided with arc angle between two place's breach 7, two breach 7, and with flange on handle, the update that the flange of handle is merely able to coincide with breach 7 overlaps 4 and blocks operating sleeve 4.The periphery of main shaft 3 is also provided with the guide vane end stop 8 of arc, and guide vane end stop 8 is provided with the stopper slot 81 of arc, and the curved angle of stopper slot 81 is predetermined angular, and the structure of stopper slot 81 defines the anglec of rotation of flange.Handle drives operating sleeve 4 to rotate a predetermined angular, the movement latched position mutually rotated between first lock tooth 61 and the second lock tooth 41, main shaft 3 connects travel switch 9, can provide corresponding working state signal (combined floodgate, separating brake and ground connection three signal) like this.
Can the operating mechanism of three-stations load switch of latched position, it comprises an operating sleeve 4, and operating sleeve 4 is in not operation period, and be in the position shown in Fig. 1, under the effect due to back-moving spring 5, operating sleeve 4 cannot be rotated by locating piece locking; During operation, update handle, is advanced to position shown in Fig. 2 by operating sleeve 4, and now operating sleeve 4 goes out of lock the constraint of block 6, can rotate with operation handlebar along (or inverse) hour hands.
Operation handlebar is cylindrical structural, and its side week, its structure was coincide with handle hole 2 structure with a breach 7 just with a side.Need the grounding switch tripping of tri-station isolating switch, by operation handlebar along panel 1A breach 7 update hole 2, turn clockwise one to B breach 7, draw out operation handle, operating sleeve 4 resets, and is locked by locating piece.Now, isolating switch is in gate-dividing state, and locked; When needing tri-station isolating switch to close a floodgate, repeat last operation: by operation handlebar along panel 1A breach 7 update hole 2, the predetermined angular that turns clockwise is to B breach 7, and draw out operation handle, operating sleeve 4 resets, and is locked by locating piece.Now, isolating switch is in "on" position, and locked; To isolating switch separating brake ground connection again, by aforesaid operations reverse operating.Owing to there is guide vane end stop 8, so the side of operation handlebar can be limited between A breach 7 and B breach 7 by limited groove 81.
This operating mechanism has following feature:
1. each position can lock respectively, simple to operate, reliably;
2. only have a handle hole 2, be one by the isolating switch of routine and the handle hole of earthed switch 2-in-1 two, each rotational angle only has the half of main switch total kilometres;
3. during mechanism operation, from ground connection, to combined floodgate, operation in two steps puts in place, avoids switch to occur misoperation, when occurring that major loop is charged never, earthed switch is closed---to separating brake---.
4. back-moving spring 5 only plays reset role, and does not play locking action, and avoid major loop when there is fault, due to electrodynamic effect, withdrawing phenomenon appears in isolating switch, prevents the extension of accident.In the utility model preferred embodiment, predetermined angular is 72 °.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection range of the present utility model.
