Embodiment
Technical spirit of the present utility model and beneficial effect can be fully understood in order to make the public; applicant will describe in detail embodiment of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to the utility model design all should be considered as protection range of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model relates to a kind of transducer draw bail of vacuum circuit-breaker, and described vacuum circuit-breaker has vacuum bubbles 1, insulated tension pole 2, connecting lever 3, operating mechanism 4 and transducer 5, and above-mentioned parts are installed on framework 10.One end of described insulated tension pole 2 connects the moved end of vacuum bubbles 1, and the other end of insulated tension pole 2 connects a swinging end of connecting lever 3, another swinging end attended operation mechanism 4 of connecting lever 3, and connecting lever 3 rotates and is arranged on described framework 10.Thus operating mechanism 4 can drive connecting lever 3 to swing, and then drive insulated tension pole 2 to move, the contact system in final drive vacuum bubbles 1 carries out conjunction point action.This operating mechanism 4 also includes energy-stored spring 41, and energy-stored spring 41 provides energy for the action of operating mechanism 4.This operating mechanism 4 is specifically as follows spring operating mechanism or permanent-magnet operating mechanism, to adapt to different client's needs.
Transducer 5 described in the utility model is arranged on the wherein arbitrary dividing plate 101 in three dividing plates on the framework 10 of vacuum circuit-breaker, thus may correspond to arbitrary connecting lever 3.Described dividing plate 101 can only have one, also can meet the demands.By such setting, make the installation site of transducer 5 convertible, adapt to vacuum circuit-breaker internal space requirements.Preferably, described transducer 5 is installed by a support, and namely support installing is on dividing plate 101, and transducer is rack-mount.
Refer to Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, transducer draw bail described in the utility model comprises connecting lever 3, transducer 5, coupling yoke 6 and locking column 7.Coupling yoke 6 is fixed on connecting lever 3 by locking column 7.Connecting lever 3 is lever piece, has a hub setting center, thus two swinging ends of connecting lever 3 can around hub setting pivot.Transducer 5 is fixed on a dividing plate 101 of framework 10, and wherein transducer 5 comprises the coupled position end 51 coordinated with coupling yoke 6, and the position of this coupled position end 51 should coordinate with connecting lever 3.Transducer 5 is for monitoring location state, and after the coupled position end 51 of external belt dynamic sensor 5 moves, position signalling is outwards transmitted according to the location status of coupled position end 51 in transducer 5 inside.Coupling yoke 6 is a metal casting, and the moulding certainly adopting performance to meet the demands also is feasible.Coupling yoke 6 comprises a shift fork pedestal 61, described shift fork pedestal 61 near transducer 5 end face on be provided with coordinate with coupled position end 51 snap in groove 62, and be provided with external part 63 away from the side of transducer 5, external part 63 coordinates with locking column 7, be preferably threaded engagement, namely external part 63 is stud and locking column 7 is thread-hole part.Locking column 7 is a Lock Part, preferably cylindric, and one end is provided with internal thread hole 71, and other end is provided with handle 72, and handle 72 drives this locking column 7 to rotate for manpower, and internal thread hole 71 is for coordinating with the stud external screw thread of external part 63.Connecting lever 3 is provided with cross installing hole 31, cross installing hole 31 coordinates with shift fork pedestal 61 outer rim of coupling yoke 6, the outer rim of shift fork pedestal 61 be length and width do not wait rectangular-shaped, it can be absorbed in cross installing hole 31 two orthogonal positions, now again by the locking of locking column 7, can ensure that coupling yoke 6 is fixing on above-mentioned two positions.In the technical scheme of the present embodiment, described cross installing hole 31 has level and vertical two fixed positions, thus coupling yoke 6 can be fixed on level or upright position.The level of coupling yoke 6 or upright position are defined by the state snapping in groove 62 on it.
The operation principle of above-mentioned parts is as follows: the coupled position end 51 of transducer 5 stretches in the fork groove 62 of coupling yoke 6, and when fork groove 62 is horizontally disposed with, coupled position end 51 is driven by the two side of fork groove 62 and moves up and down; When fork groove 62 is vertically arranged, coupled position end 51 can freely not come in contact with fork groove 62 along fork groove 62 slippage.To sum up, the connection between described transducer 5 and coupling yoke 6, the switching of released state realize by rotating coupling yoke 6, and specifically by rotation coupling yoke 6, and then the fork groove 62 rotated on coupling yoke 6 realizes.When fork groove 62 is horizontal, coupling yoke 6 fastens coupled position end 51, and this coupled position end 51 can move with connecting lever 3, thus allows transducer 5 read its kinematic parameter, and described in above, this kinematic parameter is breaker mechanic property parameter.When fork groove 62 is in vertical position, coupling yoke 6 turns over 90 °, no longer fastens coupled position end 51, thus reaches transducer 5 not with the object of breaker actuation.
