Background technology
Under the prerequisite that each item index of present miniature circuit breaker improves constantly, the applicable occasion of miniature circuit breaker also more and more widely basically all can be used miniature circuit breaker at the terminal of low-voltage distribution; The occasion that has automatic control and Long-distance Control to require simultaneously is also more and more.
The automatic control system of miniature circuit breaker is little disconnected type duplicate supply automatic control system, and is many in the market, and is little disconnected type motor-operating mechanism to the execution original paper that miniature circuit breaker carries out Long-distance Control, domestic blank, abroad also seldom.
In extensive market, under the urgent situation of demand, need a little disconnected type motor-operating mechanism that is used to control miniature circuit breaker branch, combined floodgate of exploitation to come like product outside the subrogate country, fill out the cloth domestic blank.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art the actuator circuit device of a kind of miniature circuit breaker simple and reliable for structure, lower-cost with motor-operating mechanism to be provided.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of miniature circuit breaker is with the actuator circuit device of motor-operating mechanism; Include power supply, motor, transmission device and handle, this device also includes combined floodgate, the separating brake knob of handle, four relay J 1, J2, J3 and J4; Four sensitive switch K2, K2', K3 and K3', the loop correspondence is provided with the closing circuit and the sub-gate circuit of J1b', J2b', J3b' and the J4b' composition of parallel connection.
More excellent is that said closing circuit includes series circuit K2, J4 and series circuit K2', the J1 of parallel connection.
More excellent is that said sub-gate circuit includes series circuit K3, J3 and series circuit K3', the J2 of parallel connection.
More excellent is all to be parallel with delay capacitor on said four relay J 1, J2, J3 and the J4.
More excellent is, the J1b' in the said loop is in series with J4b, and J2b' is in series with J3b.
More excellent is, said switch knob is parallel with J3a', and opening button is parallel with J4a', the J3a of series connection.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Shown in accompanying drawing 1, press switch knob, J4 connects J4a' is connected the switch knob self-locking, and J4b' connects simultaneously, and motor counter-rotating lead agency makes handle close a floodgate, making process state when handle arrives closing position;
Shown in accompanying drawing 2, touch sensitive switch K2, make the J4 outage, the J1 energising; J1b' connects, but J4 institute and the effect of delay capacitor under, motor continues some angles of counter-rotating, thereby guarantees the reliability of K2 triggering; The electric capacity time-delay finishes, the action of J4 dead electricity, and J4b connects, and motor just changes; Touch switch K1 when driven by motor mechanism forwards the centre position to; K1 is broken off, and make the J1 outage but J1 institute and the effect of delay capacitor under, some angles are just being changeed in the motor continuation; Thereby guarantee the reliability that K1 triggers; The electric capacity time-delay finishes, and the action of J1 dead electricity is broken off J1b', and motor quits work and gets into the combined floodgate halted state;
Shown in accompanying drawing 3, press separating brake and make J3 connect, J3a' connects the switch knob self-locking, and J3b' connects simultaneously, and motor is just changeing lead agency makes the handle separating brake, separating brake process status when handle arrival separating brake position;
Shown in accompanying drawing 4, touch sensitive switch K3, make the J3 outage, the J2 energising; J2b' connects, but J3 institute and the effect of delay capacitor under, motor continues some angles of counter-rotating, thereby guarantees the reliability of K2 triggering; The electric capacity time-delay finishes, the action of J3 dead electricity, and J3b connects, the motor counter-rotating; Touch switch K1 when driven by motor mechanism forwards the centre position to; K1 is broken off, and make the J2 outage but J2 institute and the effect of delay capacitor under, some angles are just being changeed in the motor continuation; Thereby guarantee the reliability that K1 triggers; The electric capacity time-delay finishes, and the action of J2 dead electricity is broken off J2b', and motor quits work and gets into the separating brake halted state.
Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
