At.
The working principle of liquid magnetic circuit breaker:
One, liquid magnetic circuit breaker combined floodgate and separating brake
Handle 211 rotates clockwise, i.e. Fig. 1 state to Fig. 8 state.Pull rod 212 is under the action of handle 211, the company of promotion
Fishplate bar 302 around axis 50 rotate, thus drive moving contact 421 take advantage of a situation needle rotation, contacted with static contact 410, complete close a floodgate.
At the same time, pull rod 212 also pushes tripping 301 to rotate clockwise, work of the lock 303 in lock reset spring 305
It is also rotated clockwise under, drive rod 304 also rotates clockwise therewith.
Conversely, in the state shown in fig. 8, rotating handle 211 counterclockwise, operation and the making process of component are on the contrary, dynamic
Contact 421 and static contact 410 disconnect, and realize separating brake.
Two, overlond trip process
Handle is closed, liquid magnetic circuit breaker conductive structure is all turned on.
As shown in Figure 6 and Figure 8, when operating current is less than specified setting current, the overlond trip of overlond trip mechanism 500
The suction that dynamic iron core 502 obtains is not enough to overcome the counter-force of overlond trip reset spring 504, and overlond trip dynamic iron core 502 cannot
It is moved to 501 direction of overlond trip static iron core；Overlond trip actuator 503 does not move up, the driving member of transmission mechanism 300
304 do not rotate, and overlond trip mechanism 500 does not work, and liquid magnetic circuit breaker conductive structure works normally.
When operating current is greater than specified setting current, what the overlond trip dynamic iron core 502 of overlond trip mechanism 500 obtained
Suction is enough to overcome the counter-force of overlond trip reset spring 504, and overlond trip dynamic iron core 502 is to 501 side of overlond trip static iron core
To movement；Overlond trip actuator 503 moves up, and the driving member 304 of transmission mechanism 300 is pushed to rotate counterclockwise.
Driving member 304 drives the rotation counterclockwise of lock 303, and lock 303 is threaded off with tripping 301, transmission mechanism tripping, starting
Mechanism 100 resets under the action of moving contact reset spring 422, moving contact 421 and 410 disjunction of static contact, liquid magnetic circuit breaker point
Lock.
Three, short-circuit tripping process
Handle is closed, liquid magnetic circuit breaker conductive structure is all turned on.
As shown in Figure 8 and Figure 9, when operating current is less than short-circuit setting current, the short circuit tripping of short-circuit tripping mechanism 600
The suction that dynamic iron core 602 obtains is not enough to overcome the counter-force of short-circuit drop-away reset spring 604, and short circuit tripping dynamic iron core 602 cannot
It is moved to short circuit tripping 601 direction of static iron core；Short circuit tripping actuator 603 does not move right, the lock 303 of transmission mechanism 300
It does not rotate, short-circuit tripping mechanism 600 does not work, and liquid magnetic circuit breaker conductive structure works normally.
When operating current is greater than short-circuit setting current, what the short circuit tripping dynamic iron core 602 of short-circuit tripping mechanism 600 obtained
Suction is enough to overcome the counter-force of short-circuit drop-away reset spring 604, and short circuit tripping dynamic iron core 602 is threaded off 601 side of static iron core to short circuit
To movement；Short circuit tripping actuator 603 moves right, and the lock 303 of transmission mechanism 300 is pushed to rotate counterclockwise.
Lock 303 is threaded off with tripping 301, transmission mechanism tripping, work of the actuating mechanism 100 in moving contact reset spring 422
With lower reset, moving contact 421 and 410 disjunction of static contact, liquid magnetic circuit breaker separating brake.
