The following describes in detail the usage steps of a circuit breaker for time-sharing and zone-dividing protection circuit according to the electric appliance power, with reference to fig. 1 to 6:

initially, the induction motor 17 is in a closed state, the arc resistance groove 18 of the arc resistance groove 18, the arc conductive swing rod 51 and the conductive threaded rod 49 are in a mutually close position, the U-shaped sliding block 30 is in any position in the arc sliding groove 19, the symmetrical conductive block 65 is in any position in the sliding resistance groove 21, the lateral sliding block 59 is in any position in the lateral sliding groove intermediate shaft 66 of the intermediate shaft 66, the vertical sliding block 48 is in any position in the resistance sliding groove 43, the conductive moving block 46 is in any position in the symmetrical sliding groove 45, and the reverse insulating block 36 is separated from the insulating pulley 38.

When the power of the electric appliance connected in the circuit breaker is too large or the number of the electric appliances is too large, the induction motor 17 is started, the driving shaft 54 is driven to rotate, the driving belt pulley 29 is driven to rotate, the driving belt 28 is driven to rotate, the driven belt pulley 27 and the driven shaft 31 are driven to rotate, the driving bevel gear 55 is driven to rotate, the rear bevel gear 57, the driven embedded shaft 56, the rear belt pulley 58, the insulating belt 40 and the pivot wheel 53 are driven to rotate, the arc resistance grooves 18 of the arc resistance grooves 18 and the arc resistance grooves 18 are driven to swing away from each other, the middle belt pulley 64 and the middle shaft 66 are driven to rotate, the insulating belt pulley 41 and the insulating shaft 39 are driven to rotate, the fixed wheel 35 is driven to rotate, when the power of the electric appliance is too large and the circuit is damaged, the fixed wheel 35 rotates to drive the reverse insulating block 36 to swing so as to jack the insulating pulleys 38 away, then the insulating pulley 38 is driven to rotate, and further the embedding wheel 37 is driven to move away from each other, at this time, the reverse insulating block 36 enables the insulating pulley 38 and the arc-shaped resistance slot 18 of the arc-shaped resistance slot 18 to be insulated, and when the intermediate shaft 66 rotates, the sliding resistance plate 20 is driven to slightly rotate, and further the three symmetrical conductive blocks 65 are driven to slide on the inner wall of the sliding resistance slot 21, so as to match different resistances to change the current, when the power needs to be supplied again, the fixed wheel 35 is turned over, so that the reverse insulating block 36 is turned over, at this time, the reverse insulating block 36 is separated from the contact with the insulating pulley 38 to cancel the insulation, and the sliding of the symmetrical conductive blocks 65 further stretches or compresses the conductive elastic wire 22, and further the U-shaped sliding block 30 is driven to slide on the inner wall of the arc-shaped sliding slot 19 at different positions to change the resistance on the arc-shaped, the arc resistance grooves 18 and the arc conductive plates 18 of the arc resistance grooves 18 move away from each other to change the resistance, and the effect of protecting the circuit is achieved by changing a series of resistances and adjusting different current sizes required to be matched with the power of the connected electric appliance.
