Above-mentioned auxiliary switch can be assembled in a switching device such as breaker, and operating assembly 30 is in linkage with to the hand of breaker
Handle, the closing position and sub-gate position for making operating assembly that the closing position of the second turntable 22 and open position be driven to correspond to breaker
It sets.And the second trip assembley therefor 29 is in linkage with to the release member of breaker, so that the trip status of the second trip assembley therefor 29 is corresponded to
The trip status of breaker.
As shown in Fig. 2, after breaker (being not drawn into figure) assembling auxiliary switch, switch from its open position to closing position
When, operating assembly 30 can drive the second turntable 22 to turn from its open position shown in Fig. 2 to closing position shown in Fig. 3 accordingly
Dynamic, under the triggering of the second turntable 22, the second microswitch 21 can switch to Fig. 3 from off-state shown in Fig. 2 during being somebody's turn to do
Shown in closed state.And it is disconnected to send out expression when being closed as break-make instruction switch (AS switches) for the second microswitch 21
The signal that road device has been connected.When not threading off when normal operation of circuit breaker, the second trip assembley therefor 29 can be in it always
Latched position, after breaker closing especially shown in Fig. 3, the second trip assembley therefor 29 being in the lock state can make second
Turntable 22 resists the elastic force of the second elastic component 24 to be maintained at closing position (will be discussed in detail hereinafter), and only when open circuit
When device switches from its closing position to open position, operating assembly 30 can just drive the second turntable 22 from shown in its Fig. 3 accordingly
Closing position rotated to open position shown in Fig. 4, because the second turntable 22 no longer touches the second microswitch 21, therefore the process
In the second microswitch 21 can switch to off-state shown in Fig. 4 from closed state shown in Fig. 3, the second microswitch 21 is made
Indicate that switch (AS switches) can send out the signal for indicating that breaker has disconnected for break-make.Auxiliary switch can repeat always Fig. 3 in this way
Switching between state and Fig. 4 states, and breaker conducting and off-state all can (AS be held by the second microswitch 21
Close) instruction.
And break down after breaker closing, after release member (being not drawn into figure) is threaded off, breaker takes off
Button can cause the second trip assembley therefor 29 of auxiliary switch to switch to trip status shown in fig. 5 from its lock-out state shown in Fig. 3.
The second trip assembley therefor 29 in trip status can discharge the second turntable 22, make the second turntable 22 in the elasticity of the second elastic component 24
(will be discussed in detail hereinafter) is rotated from the closing position of Fig. 3 to the open position of Fig. 6 under the action of power, makes the second microswitch
21 switch from its closed state shown in Fig. 3 to off-state shown in fig. 5, accurately to indicate that the circuit state of breaker occurs
Change, has become off-state from conducting state.
As shown in Fig. 2, after breaker (being not drawn into figure) assembles auxiliary switch, before operating for the first time, because of the first turntable
12 also from not moving to its open position, so when the first turntable 12 will not be related with the first trip assembley therefor 19.And when disconnected
After road device closes a floodgate, operating assembly 30 can drive the second turntable 22 from its open position shown in Fig. 2 to conjunction shown in Fig. 3 accordingly
Gate position rotates, and simultaneously, and the second turntable 22 can drive the first turntable 12 from closure position shown in Fig. 2 by its pushing part 23
It sets and is rotated between open position, the first microswitch 11 is made to switch to disconnection shown in Fig. 3 from its closed state shown in Fig. 2
State.
As shown in figure 3, after the first turntable 12 is moved to its open position, the first trip assembley therefor 19 can be in it and lock shape
State, the first trip assembley therefor 19 being in the lock state can make the first turntable 12 resist the elastic force of the first elastic component 14 to keep
In open position.Therefore when normal operation of circuit breaker, when switching between Fig. 3 and state shown in Fig. 4, the first trip assembley therefor 19 is all
The first turntable 12 is set to be maintained at its open position in its lock-out state.
It breaks down after breaker closing, after release member (being not drawn into figure) is threaded off, as described above, breaks
It is shown in fig. 5 that the dropout of road device can cause the second trip assembley therefor 29 of auxiliary switch to be switched to from its lock-out state shown in Fig. 3
Trip status.And the second trip assembley therefor 29 switched from lock-out state to trip status can drive the first trip assembley therefor 19 from its figure
Lock-out state shown in 5 switches and (will be discussed in detail hereinafter) to trip status shown in fig. 6.It is now in the of trip status
One trip assembley therefor 19 can discharge the first turntable 12, make the first turntable 12 under the action of the elastic force of the first elastic component 14 from its figure
Open position shown in 5 is rotated to closed position shown in fig. 6, makes the first microswitch 11 off-state shown in its Fig. 5
Closed state shown in fig. 6 is switched to, fault-signal is exported.Therefore (FC is opened the first microswitch 11 conduct fault detect switch
Close), fault-signal can be exported in time after breaker breaks down and threads off, to indicate that breaker breaks down.
Therefore above-mentioned auxiliary switch can realize two kinds of auxiliary switch functions simultaneously by a mechanism, it is powerful, and structure
It is more compact, production cost can be reduced.
