First receiver module 82, for receiving ammeter arrearage signal; After control assembly obtains the arrearage signal of ammeter, initiatively can make breaker open operation by starter motor 1, separating brake process process is as described above identical, but after sub-switching operation, slide block 25 not reposition position, release lever 36 does not also return, therefore, release lever 36 triggers the tripping mechanism of circuit breaker all the time, now, even if manual toggle circuit breaker handle, circuit breaker handle is made to keep "on" position by External Force Acting, also cannot connect circuit, prevent power stealing.
The present embodiment realizes the sequence of movement of divide-shut brake as mentioned below:
As shown in Figure 1, now circuit breaker is in gate-dividing state, poke rod 321 has the space moved downward in driver slot 261 as can be seen from Figure 1, thus drive block 26 can not stop poke rod 321 to move downward, now then closing by hand can be carried out, stir circuit breaker handle, rotate with the breaker close/open machine moving runner 34 arranged that links, moving runner 34 drives shifting part 32 to rotate, because poke rod 321 has the space moved downward in driver slot 261, thus the rotation of shifting part 32 and moving runner 34 is not interrupted, therefore the operation of closing by hand is carried out to circuit breaker also not interrupted.
When needs control breaker closing by miniature circuit breaker controller, its process is: by control assembly starter motor 1, slide block 25 is made to move (moving downward by Fig. 1) along screw rod 24 from home position to closing position, now, the roof of the driver slot 261 of drive block 26 contacts with the poke rod 321 of shifting part 32, drive block 26 drives shifting part 32 to do turning clockwise in Fig. 1 around shifting shaft 31, and drive moving runner 34 to rotate by the sector gear be molded on shifting part 32, thus the close/open machine action of circuit breaker is driven to complete closing operation.
After completing closing operation, the main circuit current conducting that circuit breaker 9 controls, if be provided with control assembly, controller is after the signal receiving main circuit conducting, drive motors 1 reverses (direction of rotation when just starting with closing operation during starter motor 1 is contrary), slide block 25 is made to move to home position (moving upward by Fig. 1) along screw rod 24 from closing position, (position is provided with position transducer in position in slide block 25 reposition position, once slide block 25 reposition position will trigger position transducer, signal is issued controller by position transducer, it is out of service that controller 80 controls motor 1), drive block 26 and poke rod 321 disengage, transmission matching relationship when relieving combined floodgate between toggle mechanism and moving runner 34, poke rod 321 is positioned at driver slot 261 centre position, poke rod 321 is towards the obstruction driving the motion in breaker open operation direction can not be subject to drive block 26, shifting part 32 and moving runner 34 are towards driving the rotation in breaker open operation direction also unrestricted, state as shown in Figure 3, now, just can stir the handle 91 of circuit breaker manually, make breaker open operation.
Under normal conditions, when circuit breaker closes a floodgate, as shown in Figure 3, when controlling short-circuiting device separating brake by control device of circuit breaker, its process is: starter motor 1, slide block 25 is made to move (moving upward by Fig. 1) along screw rod 24 from home position to closing position, now, projection 262 on drive block 26 withstands one end of dropout actuator 42, dropout actuator 42 is rotated along the clockwise direction shown in Fig. 2 around dropout actuator rotating shaft 41, thus drive release lever 36 to run along clockwise direction in through hole 361, and release lever 36 drives the trip gear action of circuit breaker, make circuit breaker 9 separating brake, circuit breaker handle 91 also can skip to switching-off device, this separating brake mode quick action, promptly can realize separating brake in time.
After completing sub-switching operation, main circuit current disconnects, if be provided with control assembly, controller is after the signal receiving main circuit disconnection, drive motors 1 reverses, slide block 25 is made to move (moving downward by Fig. 1) along screw rod 24 from open position to home position, (position is provided with position transducer in position in slide block 25 reposition position, once slide block 25 reposition position will trigger position transducer, signal is issued controller by position transducer, it is out of service that controller controls motor 1), projection 262 is no longer against release lever 36 simultaneously, under the effect of spring 43 pulling force, dropout actuator 42 also returns to original position, dropout actuator 42 and release lever 36 return to the position in Fig. 2, remove the triggering to tripping mechanism.Poke rod 321 has the space moved downward in driver slot 261 simultaneously.Now, the handle of circuit breaker can be stirred manually, make breaker closing.
Further, described moving runner 34 axle center is provided with gangbar 35, and described gangbar 35, through the axle center of circuit breaker 9 handle 91, drives the handle 91 of all circuit breakers 9 to rotate when described gangbar 35 drives by described moving runner 34 and rotates.
