The working principle of the starter is as follows: the opening and closing of the circuit breaker structure 2 is controlled by a spring operating mechanism 21, and a first insulating pull rod 23 drives a movable contact and a fixed contact of a corresponding circuit breaker arc extinguish chamber 24 to open and close; the on-off of the contactor structure 3 is controlled by an electromagnetic operating mechanism 31, and a movable contact and a fixed contact of a corresponding contactor arc extinguish chamber 34 are driven to be on-off by a second insulating pull rod 33;

when the spring operating mechanism 21 stores energy and works, the energy storage motor 2121 drives the rotating disc 2124 to rotate, so that the closing spring 2131 is driven to stretch, and after the closing spring 2131 stores energy in place, power is contacted with the energy storage sector plate through the roller on the cam 2123 and the energy storage sector plate is restrained and maintained with the closing half shaft. When the electromagnetic operating mechanism 31 needs to be switched on, a switching-on button or a switching-on release is manually pressed to push a switching-on half shaft to rotate, so that the constraint of an energy storage sector plate and a roller is removed, the energy of a switching-on spring 2131 is released to drive a cam 2123 to rotate, the cam 2123 impacts a connecting plate 2152 to rotate, an output crank arm 2162 is rotated through the connecting rod 2153 to drive the first insulating pull rod 23 to move so as to realize switching-on, the indicating plate 52 and the connecting rod 2153 synchronously move, the moving direction of the indicating plate 52 is the same as that of the connecting rod 2153, because the interlocking push rod 51 only has the degree of freedom of sliding between the circuit breaker structure 2 and the contactor structure 3, in the moving process of the indicating plate 52, the input end of the interlocking push rod 51 and the lower end of the bending part of the indicating plate 52 are far away from each other to enable the output end of the interlocking push rod 51 to move towards the direction, when the switch-on is in place, the holding piece is contacted with the roller on the connecting plate and is restrained with the switching-off half shaft, and the switch-on action is finished;

then when contactor structure 3 closes the floodgate: the electromagnetic actuator 3121 drives the transmission main shaft 313 to rotate forward through the base 311 and realize closing, and the second opening spring 317 compresses and stores energy, the upper holding pawl 3181 buckles the upper holding roller on the transmission main shaft 313, the blocking pin of the rotating block 3182 blocks the upper holding pawl 3181, and the lower holding pawl 3183 buckles the lower holding roller on the rotating block 3182, so that the switch is kept at the closing position.

Compared with the technical background, the invention has the following advantages:

1. through integrating circuit breaker structure 2 and contactor structure 3, and still be provided with insulating looks post 4 and interlocking device 5 between circuit breaker structure 2 and contactor structure 3, not only have the respective function of circuit breaker and contactor, can also realize interlocking and the breaking function of circuit breaker to the contactor through interlocking device 5 and insulating looks post 4, solved protecting roughness and current capacity is less, mechanical interlocking is difficult to realize, the problem that the cost is high in the background art.

2. The starter switch integrates a circuit breaker structure 2 and a contactor structure 3, the size of the starter switch is common to that of a vacuum contactor fuse combined electrical appliance or a vacuum circuit breaker, and even the size of the starter switch can be exchanged, wherein the circuit breaker structure 2 and the contactor structure 3 are respectively horizontally arranged and mutually aligned up and down, and the circuit breaking channels 22 are arranged side by side, so that the starter switch has the advantages of simple scheme, small width and compact structure.

In summary, the circuit breaker structure 2 and the contactor structure 3 have corresponding functions, and the insulating phase column 4 and the interlocking mechanism 5 are arranged between the circuit breaker structure and the contactor structure, so that the circuit breaker has the advantages of compact structure, multiple functions and low manufacturing cost.

The invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
