The complete working principle and working procedure of the above embodiments 1-2 are as follows:
initial state of each part: the torsion spring 15 is in a deformation state, and torsion acts on the rotating rod 14 and the first gear 11; the spring plate 23 is in contact with the contact block 22, the spring plate 23 is in a deformed state, the contact block 22 is in a deformed state, and the elastic force acts on the contact block 22; the first gear 11 drives the contact resisting rod 19;
the first schedule is 1 to all working schedules of the compression bar 18:
referring to fig. 1 to 6, when a circuit fails and the current in the circuit in the breaker body 1 increases many times instantaneously, the internal components are triggered to spring down the switch 2, the current conducted by the wire 6, the electromagnet 7 and the bimetal 8 is also increased many times instantaneously when the wire 6, the electromagnet 7 and the bimetal 8 are connected in parallel with the circuit in the breaker body 1, if the switch 2 is blocked during the spring down process or the electromagnet in the switch does not work smoothly with the striker, the switch 2 cannot spring down smoothly to disconnect the circuit, and at this time, because the current conducted by the wire 6, the electromagnet 7 and the bimetal 8 also increases many times instantaneously, the temperature on the bimetal 8 increases instantaneously, the bimetal 8 is a composite material composed of two or more metals or other materials with proper properties, when two or more than two bimetallic strips with different thermal expansion coefficients are heated, the bimetallic strips bend into an arch-shaped shell, when the bimetallic strips are heated, a narrow bimetallic strip bends into an arc with a certain radius, at the moment, the electric wire 6, the electromagnet 7 and the bimetallic strip 8 no longer form a passage, so that the electromagnet 7 is powered off, the magnetic force disappears, because the torsion spring 15 is in a deformation state, torsion force acts on the rotating rod 14 and the gear one 11, when the electromagnet 7 no longer adsorbs the iron block 9, the pull rope 10 and the connecting block 12 cannot continuously pull the gear one 11, the torsion spring 15 drives the gear one 11 to rotate anticlockwise, the gear one 11 and the gear two 16 are meshed with each other, the gear two 16 rotates clockwise, the transmission rod 17 and the compression rod 18 are driven to press the switch 2, the auxiliary switch 2 ejects down to open a circuit, and the radius of the gear one 11 is a power arm, the distance from the center of the second gear 16 to the pressing rod 18 is a resistance arm, and the torsion force of the torsion spring 15 is power, which is known as follows: in the device, the power arm and the resistance arm are all fixed values, and the power arm is twice as much as the resistance arm, so that the resistance is twice as much as the power, namely, the compression bar 18 can overcome larger resistance by adding the power arm, so that the compression bar 18 can not assist the switch 2 to smoothly bounce down to open a circuit due to the clamping and the tightening of the switch 2;
the second schedule is all work progress of the abutment lever 19 to the slot 25:
referring to fig. 7 to the drawing rope 10, when the gear one 11 drives the gear two 16 to rotate, the gear one 11 and the gear two 16 respectively drive the contact rod 19 and the plugboard 24 to rotate, the contact rod 19 is in contact with the lower contact block 22 in the rotating process, the contact block 22 is made of rubber, the contact block 22 deforms, namely the lower half part of the contact block 22 is folded and deformed to the rear side until the lower half part of the contact block 22 is separated from the mounting ring 20, the contact block 22 is not in contact with the mounting ring 20 at the moment, the spring plate 23 is in contact with the contact block 22, the spring plate 23 is in a deformation state, the spring plate 23 is made of a metal material, the contact rod 21 is driven to move forwards by the elasticity of the spring plate 23, meanwhile, the gear two 16 drives the plugboard 24 to rotate clockwise, and when the torsion spring 15 is recovered to be in an initial state, the gear one 11 and the gear two 16 stops rotating until the contact rod 24 is vertical to the horizontal plane, and meanwhile, the switch 21 is inserted into the slot 25 and the switch 21 is not in contact with the slot 18, and the switch 18 cannot be lifted by the aid of a pressing rod 2, and the switch is not lifted by the person 2;
after the professional completes fault checking and removing, the user opens the shell 3 to pull the inserting rod 21 backwards, so that the inserting rod 21 is separated from the slot 25, the upper abutting block 22 abuts against the spring plate 23, the spring plate 23 is driven to deform, the lower abutting block 22 abuts against the mounting ring 20, the spring plate 23 abuts against the upper abutting block 22, the lower abutting block 22 abuts against the mounting ring 20 to form a stable clamp and state, the position of the inserting rod 21 is fixed, then the user can smoothly lift the switch 2 and drive the pressing rod 18 to lift, recovery of a circuit is completed, because the switch 2 completes circuit disconnection, current on the bimetallic strip 8 disappears, the temperature on the bimetallic strip 8 is recovered to be normal, the bimetallic strip 8 is not bent any more, so that after the circuit in the circuit breaker main body 1 is recovered, the electromagnet 7 is electrified to generate magnetic force, the current is absorbed, the pull rope 10 and the pulling gear 11 are driven to rotate clockwise to recover the initial state, the electromagnet 7 is larger than the torsion spring 15, and the lower torsion spring 15 is repeatedly deformed when the torsion spring 15 is stressed, and the circuit in the process is repeatedly deformed, and the circuit is deformed, so that the circuit is 18 is deformed.
