Operation principle:
The operation sequence process of circuit breaker from the experiment position to the service position:
Circuit breaker is when the experiment position, and the pole in the pole 24 is in gate-dividing state.Circuit breaker blocking lever 38 is retracted in the breaker body 31 at this moment; Clockwise rotate leading screw; Circuit breaker slides to the left side of Fig. 2 along guide rail; Drive, the last moving conductive contact arm 21 of the pole in the pole 24 inserts in the fixed contact box 1 with following moving conductive contact arm 22, and circuit breaker is from testing the position to the service position.At this moment, can carry out closing operation to circuit breaker.Press the breaker closing button; The on/off switch magnetizing coil of the permanent magnet mechanism 32 in the breaker body overcomes the moving iron core 33 of permanent-magnetic field intensity drive permanent magnet mechanism to left movement after charged; The moving iron core 33 of permanent magnet mechanism drives oscillating bearing pull bar 35 through transmission mechanism 23 and moves downward; Insulated tension pole 30 and moving contact 27 in interlock connecting lever 40, the pole 24 moves upward simultaneously, makes the moving contact 27 of pole 24 interior poles and fixed contact 26 fit, and major loop of circuit breaker is connected.Simultaneously, because oscillating bearing pull bar 35 drives blocking lever connecting lever 36 action downwards in making process, make to be installed in the also action downwards of circuit breaker blocking lever 38 on the blocking lever connecting lever 36.Stretch out breaker body 31, pin circuit breaker interlocker 17, make breaker body 31 and pole 24 under "on" position, can't slide front and back.The reed switch relay 42 that is installed in breaker body 31 bottom, right side is simultaneously connected with the magnetic approach switch 34 on the chassis supports plate 3, makes the indicator light 41 of circuit breaker position light, and operating personnel can be in the service position to circuit breaker from the cabinet visual observation.
Circuit breaker from the service position to the experiment position the operation sequence process:
When circuit breaker was in "on" position in the service position, breaker body 31 can't be slided front and back with arc control device 24.At this moment; Press the breaker open operation button; The on/off switch magnetizing coil of the permanent magnet mechanism 32 in the breaker body 31 overcomes permanent-magnetic field intensity after charged and drives the moving iron core 33 of permanent magnet mechanism and move right; The moving iron core 33 of permanent magnet mechanism drives oscillating bearing pull bar 35 and moves upward through transmission mechanism 23, and insulated tension pole 30 and the moving contact 27 in interlock connecting lever 40, the drive pole 24 moves downward simultaneously; Make the moving contact 27 of pole 24 interior poles separate with fixed contact 26, major loop of circuit breaker breaks off.Simultaneously,, make to be installed in the also upwards action of circuit breaker blocking lever 38 on the blocking lever connecting lever 36, be withdrawn in the breaker body 31 because in the separating brake process, oscillating bearing pull bar 35 drives upwards action of blocking lever connecting lever 36.Rotate counterclockwise leading screw, slide to the right side of Fig. 2, the moving conductive contact arm 21 that drives on the pole 24 is extracted fixed contact boxes 1 out with following moving conductive contact arm 22, circuit breaker from the service position to testing the position.The reed switch relay 42 that is installed in breaker body 31 bottom left is simultaneously connected with the magnetic approach switch 34 that is contained on the chassis supports plate 3; Make bright 41 of circuit breaker position indicator light, operating personnel can be in the experiment position from the cabinet visual observation to circuit breaker.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
