Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As Fig. 1-shown in Figure 4, the optional circuit breaker of the utility model overlond trip comprises warning device and trip gear, and warning device and trip gear all are arranged in the pedestal 1.
Warning device comprises thermal element 2, bimetal leaf 3, touch part 4, trigger board 5, warning draw bar 6, rotating shaft 14, signal picker 7.Warning draw bar 6 is set in the rotating shaft 14, can 14 rotate around the shaft, and the two ends of rotating shaft 14 are fixed in the pedestal 1.Be set with torsion spring 10 in the rotating shaft 14, a pair of torsion spring pin of torsion spring 10 is kept out respectively on the pedestal 1 and on the warning draw bar 6.Warning draw bar 6 is provided with trigger board 5, and trigger board 5 keeps at a certain distance away with touch part 4.Pedestal 1 is provided with fixed head 9, and signal picker 7 is fixed on the fixed head 9, is positioned on the rotation path of trigger board 5.Signal picker 7 in the present embodiment is a sensitive switch, but it is not limited to sensitive switch, and it can also be travel switch, near the switch of switch or other similar effect.When overload took place circuit, thermal element 2 heatings added thrermostatic bimetal-plate 3 it are occured bending and deformation, and touch part 4 moves toward trigger board 5 directions, until contacting with trigger board 5, trigger board 5 were rotated, thus driving signal collector 7, and this moment, torsion spring 10 was compressed.Signal picker 7 is connected with warning device, and this warning device can be signal lamp or buzzer, and when signal picker 7 was pushed, warning device can send alarm signal.After circuit recovered normally, bimetal leaf 3 set back under the effect of self-characteristic, and touch part 4 breaks away from trigger board 5, and warning draw bar 6 resets under the effect of torsion spring 10.On warning draw bar 6, also be provided with locating part, guarantee that it is parked in initial position.
Trip gear comprises dropout draw bar 11 and release 12.Release 12 is located on the rotation path of dropout draw bar 11, and 11 rotations of dropout draw bar can touch release 12 and finish the action of threading off.Dropout draw bar 11 and warning draw bar 6 in the utility model all are sleeved in the rotating shaft 14.Dropout draw bar 11 has two kinds, the first dropout draw bar 111 and the second dropout draw bar 112.The first dropout draw bar 111 is provided with on replace block 13, the second dropout draw bars 112 does not have replace block 13.This replace block 13 is positioned on the rotation path of warning draw bar 6, and is corresponding with the position of trigger board 4.When in the rotating shaft 14 the first dropout draw bar 111 being installed, warning draw bar 6 can promote the first dropout draw bar 111 and rotate, and triggers release 12 and threads off circuit breaker tripping.When in the rotating shaft 14 the second dropout draw bar 112 being installed, when warning draw bar 6 rotates, can not promote the second dropout draw bar 112 and rotate, so circuit breaker can not being threaded off.Can realize the function of threading off or not threading off by replacing two kinds of dropout draw bars 11, and there are difference in 11 of two kinds of dropout draw bars at replace block 13 places, only need during manufacturing slightly change and get final product the saving cost mould.Dropout in the present embodiment is optional to be realized by replace block 13 is set on dropout draw bar 11, but it is not limited to this implementation, it can also be arranged on replace block 13 on the warning draw bar 6, perhaps position thickening that dropout draw bar 11 is cooperated with warning draw bar 6 etc.Present embodiment does not limit the utility model and also has other multiple implementation.
Further, the size of circuit breaker overload setting value and the distance relation in direct ratio between touch part 4 and the trigger board 5, promptly distance is big more between touch part 4 and the trigger board 5, and the overload setting value is big more.The utility model also provides a kind of adjusting device 8 to adjust distance between touch part 4 and the trigger board 5, thereby changes the overload setting value of circuit.This adjusting device comprises poke rod and knob.Warning draw bar 6 is provided with the groove of stirring that cooperates with poke rod, and poke rod is plugged on to be stirred in the groove.Knob can drive poke rod and rotate, poke rod only otherwise be on the center of rotation of knob, the draw bar 6 that just can promote to report to the police moves axially along rotating shaft 14.In the present embodiment on the trigger board 4 face relative with touch part 5 be the inclined-plane, therefore when the warning draw bar moves axially, the distance between trigger board 4 and the touch part 5 changes, thus setting value is transshipped in change.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
