The switching-on and switching-off process of the switch is described in detail as follows:

in the initial state, the bump 6b1 of the driving gear 6b0 abuts against the pushing rod 5b1, and the pushing rod 5b1 abuts against the moving contact assembly 5b2 and overcomes the counterforce of the counterforce spring 5b4, so that the second moving contact assembly 5b2 and the second fixed contact assembly 5b5 are kept separated.

Further, when the handle 2a0 leaves the brake separating position, the first state detecting device 7b1 is triggered and transmits a signal to the electronic controller 700, and the electronic controller 700 starts to drive the motor 6a0 to rotate after receiving the signal transmitted by the first state detecting device 7b1, and drives the third driven gear 6b0 to operate through the driving gear set 6a1, the protrusion 6b1 also rotates along with the signal, the highest point of the protrusion 6b1 avoids the pushing rod 5b1, then the mutual acting force between the protrusion 6b1 and the pushing rod 5b1 disappears, and the second movable contact 5b2 starts to rotate around the shaft 5b3 under the action of the reaction spring 5b4 until contacting with the second fixed contact 5b 5. At this time, the motor-driven reduction assembly 600 continues to rotate, and when the signal of the second state detecting device 7b2 of the fourth driving gear 6a32 is triggered, the motor 6a0 stops rotating, thereby completing the manual closing of the first contact system 5a0 and the automatic closing of the second contact system 5b0 by the electric operating mechanism 600. In a preferred embodiment, the second contact system 5b0 is closed before the first contact system 5a 0.

Manual brake opening:

specifically, when the handle 2a0 is manually operated to perform the opening operation of the switch, the operating mechanism 200 drives the first contact system 5a0 to complete the opening operation under the driving of the handle 2a 0.

Further, when the handle 2a0 returns to the open position, the first status detecting device 7b1 is triggered and transmitted to the electronic controller 700. When the motor 6a0 is operated, the highest point of the bump 6b1 on the third driven gear 6b0 again abuts against the pushing rod 5b1, and the reaction force of the reaction force spring 5b4 is overcome under the action of the pushing rod 5b1, so that the movable contact component 5b2 and the fixed contact component 5b5 on the second contact system 5b0 are separated again. The motor 6a0 continues to rotate, and when the signal of the third status detection device 7b3 on the fourth driving gear 6a32 is triggered, the motor 6a0 stops rotating, thereby completing the manual opening of the first contact system 5a0 and the automatic opening of the second contact system 5b0 through the electric operating mechanism 600. In a preferred embodiment, the first contact system 5a0 is opened before the second contact system 5b 0.

Automatic brake opening:

specifically, the external signal is triggered, the external signal may be an operating signal such as a residual current operating signal, an overcurrent delay tripping operating signal, a remote control tripping, and the like, the electronic controller 900 sends an instruction to the shunt release, the shunt release receives the instruction from the electronic controller 900 and then operates, the trip lever 2b1 is driven by a pull rod 910910 arranged on the shunt release to operate, the trip lever 2b1 is driven by the pull rod 910910 to rotate, the trip lever 2b1 is in contact with the latch 2b2, the latch 2b2 is hinged to the handle 2a0 through a shaft 2a2, when the trip lever 2b1 rotates, the latch 2b2 rotates upward, at this time, the stable state of the operating mechanism 2b0 is broken, and the first contact system 5a0 automatically opens.

Further, when the first contact system 5a0 is switched off due to the triggering of the shunt release, the handle 2a0 returns to the switching off position, the signal of the first state detection device 7b1 is triggered, the motor 6a0 starts to operate, and drives the second contact system 5b0 to be also switched off rapidly, and the switching off process of the second contact system 5b0 is the same as the switching off process, and is not described again. At this time, the motor 6a0 continues to rotate, and when the signal of the third status detection device 7b3 on the fourth driving gear 6a32 is triggered, the motor 6a0 stops rotating, thereby completing the automatic opening operation of the first contact system 5a0 by a trip device and the second contact system 5b0 by the electric operating mechanism 600.

In a preferred embodiment, since the switch itself is subjected to an excessive current, the overcurrent release of the trip device 900 operates, and the trip device 900 can drive the pull rod 910 to further drive the trip rod 2b1 to perform an unlocking operation, and then the first contact system 5a0 is switched off, when the handle 2a0 returns to the switching-off position, under the trigger of the signal of the first state detection device 7b1, the second contact system 5b0 is also switched off under the driving of the motor-driven speed reduction assembly 600.

Of course, the first contact system 5a0 can realize automatic opening of the brake by the trip device 900, and also can realize automatic opening of the brake by the electric operating mechanism 600, specifically, the motor 6a0 is turned on, the first driven gear set 6a3 is turned on by the driving of the driving gear set 6a1, the stopper 6a33 on the first driven gear set 6a3 is turned together with the first driven gear 6a31 and the second driven gear 6a32, and when the stopper 6a33 is in contact with the connecting rod 6a34 disposed between the electric operating mechanism 600 and the first contact system 5a0, the connecting rod 6a34 is turned on by the stopper 6a33, so as to drive the first movable contact 5a1 to turn, thereby realizing automatic opening of the brake of the first contact system 5a 0.

Automatic closing:

in particular, due to the external signal triggering, the motor 6a0 rotates, and the second contact system 5b0 may be closed by the third driven gear 6b0 according to the above. The motor 6a0 continues to rotate, when the second driven gear 6a32 rotates to the position of meshing with the incomplete gear on the handle 2a0, the second driven gear 6a32 will drive the handle 2a0 to rotate together, so that the first contact system 5a0 is switched on, the motor 6a0 continues to rotate, and when the signal of the second state detection device 7b2 on the fourth drive gear 6a32 is triggered, the motor 6a0 stops rotating, so that the automatic switching-on operation of the first contact system 5a0 and the second contact system 5b0 is realized through the electric operating mechanism 600.
