When a failure occurs it, delayed time system 200 in response to the failure actuator handling system 300, then operating system
The moving contact 402 of 300 operation electric contact-systems 400 is separated with static contact 401, so that breaker 1 is cut from switch closed condition
Change to switch open condition.
The operating process of breaker 1 described in detail below.Fig. 5 A-5E are the section views according to breaker 1 of the present utility model
Figure, respectively illustrates multiple states during breaker 1 is operated.
As shown in Figure 5A, it illustrates breaker 1 be in switch closed condition, switch closed condition be also breaker 1 just
State when often operating.Now, static contact 401 and moving contact 402 are contacted.In addition, armature 301 is separated with limit 203, handle
305 is in the close position.Electric current flows to the first binding post 511 according to above-mentioned current trend from the second binding post 521.
As shown in Figure 5 B, it is in switch open condition it illustrates breaker 1.Now, static contact 401 and moving contact 402
Separation, handle 305 is in an open position, and electric current can not flow to the first binding post 511 from the second binding post 521, so that disconnected
Circuit breaker 1.
In case of need, operator can manually cut-off breaker 1, that is, manually by breaker 1 from figure
Switch closed condition shown in 5A switches to the switch open condition shown in Fig. 5 B.Specifically, operator is manually by handle 305
Open position is switched to from closing position, now, the drivening rod mechanism 302 of handle 305 is moved, then drive connecting rod 304 to transport
It is dynamic, the moving contact 402 being fixed in connecting rod 304 is disengaged and is no longer contacted with static contact 401 from static contact 401,
So that the switch closed condition shown in breaker 1 from Fig. 5 A switches to the switch open condition shown in Fig. 5 B.
Conversely, the switch open condition shown in breaker 1 from Fig. 5 B manually can also be switched to Fig. 5 A institutes by operator
The switch closed condition shown.Specifically, handle 305 is manually switched to closing position, now, hand by operator from open position
The drivening rod mechanism 302 of handle 305 is moved, and then drives connecting rod 304 to move, and thus makes to be fixed on dynamic tactile in connecting rod 304
First 402 contact with static contact 401, so that the switch open condition shown in breaker 1 from Fig. 5 B switches to opening shown in Fig. 5 A
Close conjunction state.
Fig. 5 C-5E respectively illustrate breaker 1 when breaking down and are automatically switched to switch opening from switch closed condition
The process of state.
In the normal operation period, breaker 1 is in the switch closed condition shown in Fig. 5 A.When a failure occurs it, for example when
Occur circuit overloads or short circuit when, the electric current for flowing through breaker 1 is significantly increased, that is, flow through magnet coil 202 electric current show
Increase is write, the magnetic force that thus magnet coil 202 is produced increased dramatically, and be enough armature 301 being attracted in limit 203, also
Be now armature 301 contact jaw in the presence of the magnetic force of increase rain limit 203 contact, as shown in Figure 5 C.
While armature 301 is attracted to limit 203, the pivot axis of armature 301 turn, then the actuation ends of armature 301
Actuation trip mechanism 303.The connecting rod 304 of the actuation link mechanism 302 in the case where being activated by armature 301 of tripping mechanism 303,
Move connecting rod 304.The motion of connecting rod 304 causes the moving contact 402 being fixed in connecting rod 304 to move together, so that
Moving contact 402 is set to depart from the contact with static contact 401, as shown in Figure 5 D.
In the case where static contact 401 is separated with moving contact 402, breaker 1 is disconnected, and electric current can not be from the second wiring
Terminal 521 flows to the first binding post 511.Now, in magnet coil 202 there is no electric current, then magnet coil 202 is no longer produced
Magnetisation power, sucking action is no longer produced to armature 301, thus, and the pivot axis of armature 301 transfer to depart from the contact with limit 203,
As shown in fig. 5e.In this case, breaker 1 is in the switch open condition shown in Fig. 5 B.
It can be seen that, in case of a failure, breaker 1 can be automatically from the switch closed condition shown in Fig. 5 A
Switch to the switch open condition shown in Fig. 5 B.And after Failure elimination, operator, which can be manually operated, makes breaker 1
The switch closed condition shown in Fig. 5 A is switched to from the switch open condition shown in Fig. 5 B.
Operated by the mutual cooperation of delayed time system 200, operating system 300 and electric contact-system 400, the He of static contact 401
Moving contact 402 can cooperate to realize the closure or opening of breaker 1, so that the circuit connection of correlation is connected or disconnects,
To be played a protective role in the case of overload or short circuit.
