Description
Technical field
The utility model relates to the control and protective switching device field in the low-voltage electrical apparatus, particularly, relates to a kind of operating mechanism of control and protective switching device.
Background technology
" control and protective switching device " (or being called the control protector) is the novel product in the low-voltage electrical apparatus, and its product category code name is " CPS ", is the abbreviation of English " Control and Protective Switching Device ".CPS can realize control and defencive function integrated, that internal coordination cooperates at the product of single structure form, can substitute multiple traditional discrete components such as circuit breaker (fuse), contactor, overload (or overcurrent, disconnected phase) protection relay, starter, isolator.KB0 is the large series products of domestic first generation CPS.KB0 is mainly used in exchanging 50Hz(60Hz), rated voltage comprises the electric current under the overload condition of regulation to 690V, electric current connection in the electric power system of 0.16A to 125A, carrying and the disjunction normal condition, and can connect, carry and the non-normal condition of disjunction regulation under electric current (such as short circuit current).KBO adopts the version of modular single product; the major function of integrated traditional circuit breaker (fuse), contactor, overload (or overcurrent, disconnected phase) protection relay, starter and isolator has far distance automatic controlling and directly the function of manpower control, panel are indicated and dynamoelectric signal warning function and have the time meta-current protection characteristic (having inverse time lag, specified time and instantaneous three section protection characteristic) of cooperation on the spot.Match as required functional module or annex, can realize the load of motor of motor load, Fraquent start to general (not Fraquent start) and control and the protection of power distribution circuit load.
In the prior art, circuit breaker has two types on warning tripping type and alarm non-tripping type.Warning tripping type circuit breaker will make the warning device action and drive trip gear and move to thread off when circuit overload or short circuit.

In the present embodiment, described warning retainer 19 and described dropout retainer 20 that described retainer 1 comprises are one-body molded, be to be provided with on the described retainer 1 for the warning stop ledge 102 that engages with the described alarm card platform 17 of described warning cam 2 or separate and the dropout stop ledge 101 that engages or separate with described the trip arm 18 of described deflecting cam 3, wherein, the drop-away time of described dropout braking boss 101 and described deflecting cam 3 is greater than the drop-away time of described warning stop ledge 102 and described warning cam 2.Except above-mentioned, other structures of the described operating mechanism of the present embodiment are identical with operating mechanism among the embodiment one, no longer describe in detail at this.
The operating principle of described retainer 1 is as follows:
Described driving lever 7 is when the fire-fighting position, described warning push rod 6 receives overload signal and moves and promote described retainer 1 rotation, because the drop-away time of described dropout braking boss 101 and described deflecting cam 3 is greater than the drop-away time of described warning stop ledge 102 and described warning cam 2, therefore, described warning cam 2 and described alarm, brake boss 102 are with the dropout output alarm signal, simultaneously, described warning push rod 6 stops mobile, described dropout braking boss 101 is not yet threaded off with described deflecting cam 3, thereby satisfies the only fire-fighting demand of alarm non-tripping of transshipping.
Described driving lever 7 is when home position, because described release lever 8 contacts with described warning cam 2, therefore, the rotation of described warning cam 2 will drive described release lever 8 rotations and promote described retainer 1 and be rotated further, export trip signal so that described deflecting cam 3 is threaded off with described dropout braking boss 101, thereby satisfy the primary demand that overload-alarm is threaded off.
Embodiment three
In the present embodiment, described warning push rod 21 and described dropout push rod 22 that described warning dropout push rod 6 comprises are one-body molded, be that described warning dropout push rod 6 can either receive overload signal and moves, also can receive over-current signal and move, at this moment, described warning dropout push rod 6 receives stroke that overload signals move and is less than and receives the stroke that over-current signal moves.In addition, the operating mechanism among other structures of the described operating mechanism of the present embodiment and the embodiment one or identical with operating mechanism among the embodiment two no longer is described in detail at this.
The operating principle of described warning dropout push rod 6 is as follows:
Described driving lever 7 is when the fire-fighting position, described warning dropout push rod 6 receives overload signal and moves and promote described retainer 1 rotation, because the stroke that described warning dropout push rod 6 reception overload signals move is less than and receives the stroke that over-current signal moves, described warning cam 2 is with the dropout output alarm signal, owing to just stopping mobile behind the described warning dropout push rod 6 mobile alarm strokes, therefore, described deflecting cam 3 is not yet threaded off, thus the fire-fighting demand of alarm non-tripping only when satisfying overload.
Described driving lever 7 is when home position, because described release lever 8 contacts with described warning cam 2, therefore, the rotation of described warning cam 2 will drive described release lever 8 rotations and promote described retainer 1 and be rotated further, export trip signal so that described deflecting cam 3 is threaded off with described dropout braking boss 101, thereby satisfy the primary demand that the overload alarm is threaded off.
Obviously, above-described embodiment only is for example clearly is described, is not the restriction to execution mode.Those of ordinary skill in the field can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.The apparent variation of being extended out thus or change still are among the protection range of the utility model creation.
