Embodiment
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
The combined floodgate of circuit breaker and separating brake: when middle moment spent by spring, switching-in spring releases energy, and impels energy-storage system to be rotated counterclockwise and drives transmission swing arm to rotate, and drives power transmission shaft that switch is closed a floodgate, separating brake swing arm simultaneously fastens separating brake semiaxis, makes circuit breaker be in "on" position.Pull separating brake handle, separating brake semiaxis is rotated, and separating brake connecting lever is triped, and drive link makes switch separating brake under the drive of tripping spring.
As shown in figs. 1-7, closing locking device, comprise the movable cover plate 4 for cover cap grounding shaft 1 and isolation axle 2, cover plate 4 is the fronts being arranged on grounding shaft 1 and isolation axle 2, and grounding shaft 1 and isolation axle 2 wear and stretched out by panel 3.The up and down of cover plate 4 is controlled by linkage 5, and described linkage 5 is the lever constructions be made up of bent plate 51, guide plate 52 and guide rod 53, and supporting bracket 55 is supports of lever construction, and guide plate 52 and the pin joint of supporting bracket 55 are fulcrums of lever construction; Bent plate 51 and guide rod 53 are the two ends as lever construction; Guide plate 52, supporting bracket 55 and bent plate 51 are articulated with the second waist hole 521 jointly, make the rotation of this lever construction more flexible; Guide plate 52 can decline along with the rising of bent plate 51 or decline or rise.Bent plate 51 has two the first waist holes 511, and bent plate 51 is movably fixed on top board 54, and bent plate 51 and top board 54 are fixed on the first waist hole 511 by two nut (not shown), and bent plate 51 can move up and down along the direction in the first waist hole 511.At " Contraband " shape limiting plate 56 at panel 3 rear, on described limiting plate 56, lower cross plate 561 respectively has spacing hole 562, and described guide rod 53 is each passed through upper and lower spacing hole 562, guarantees that guide rod 53 can only be vertically up and down.The guide rod 53 of linkage 5 is fixedly connected with cover plate 4 by stud 9, stud 9 is set with torsion bar 10, guide groove 563(Fig. 5 is had) at the vertical direction of limiting plate 56, wherein stud 9 is each passed through cover plate 4, limiting plate 56 and guide rod 53, the dumbbell shaped that guide groove 563 is little in large centre, two, torsion bar 10 is in thin-and-long, torsion bar 10 minor face is that torsion bar can along guide groove 563 up and down (Fig. 7) when moving towards for level, when torsion bar 9 enters guide groove 563 end, rotating the torsion bar 10 i.e. long limit of torsion bar 9 is level trend (Fig. 6), and torsion bar 9 will be stuck in guide groove 563 end.Between the lower cross plate 561 and stud 9 of limiting plate 56, be also provided with back-moving spring 57, back-moving spring 57 is sleeved on guide rod 53.In linkage 5, bent plate 51 is located by rotatable connecting lever 6, and be provided with protruding projection 512 at bent plate 51, connecting lever 6 is provided with the stuck point 61 propping up projection.Cover plate 4 has two profiled holes 41.Described cover plate 4 has location notch 42, and described panel 3 is provided with alignment pin 32, and described alignment pin 32 slides up and down along location notch 42, and limiting cover plate 4 can only be up and down.
As illustrated in fig. 1 and 2, when circuit breaker is in "on" position, swing arm 8 can be freely movable; rotating connecting lever 6 makes stuck point 61 prop up projection 512 on bent plate 51; prevention bent plate 51 rises and is namely in decline state, and guide rod 53 rises and drives cover plate 4 to close isolation axle 1 and grounding shaft 2, proterctive equipment.Now back-moving spring 57 is in extended state, and wherein torsion bar 10 is positioned at the upper end of guide groove 31, rotates torsion bar 10 and makes it be fixed on the top of guide groove 31, avoid linkage 5 to repeat to move up and down.
As shown in Figures 3 and 4, when circuit breaker is in gate-dividing state, rotating connecting lever 6 makes stuck point 61 depart from projection 512, and rotate torsion bar 10 and make stud 9 can be up and down along guide groove 31, back-moving spring 57 compresses and drives guide rod 53 to move down, until torsion bar 10 moves to below guide groove 31, again rotate torsion bar 10 and fix.In addition, bent plate 51 rises and props up swing arm 8 under lever principle effect, forbids breaker closing, ensures the safety of operating personnel; Now isolate axle 1 and grounding shaft 2 corresponding with two profiled holes 41 of cover plate 4 respectively, isolation axle 1 and grounding shaft 2 can free operant.
Above-described, be only preferred embodiment of the present utility model, the scope that this practicality is implemented can not be limited, every equalization change of doing according to the utility model claim and decoration, all should still belong in scope that the utility model contains.
