The second transmission member 12 can rotate around the main shaft 10, the opening and closing actuator 400 further includes a first elastic member 14, the first elastic member 14 can be a spring, an elastic sheet, or the like, the elastic force of the first elastic member 14 acts on the second transmission member 12, and the elastic force direction of the first elastic member 14 is a direction away from the second electrical contact 122, when the first abutting surface 110 abuts against the second abutting surface 120 and the first electrical contact 121 contacts the second electrical contact 122, due to the acting force between the first abutting surface 110 and the second abutting surface 120, the acting force between the first electrical contact 121 and the second electrical contact 122, and the elastic force of the first elastic member 14, the opening and closing actuator 400 is balanced in force, and the first transmission member 11 and the second transmission member 12 are kept relatively stationary. And the position of the second electrical contact 122 is fixed, the first electrical contact 121 and the second electrical contact 122 can maintain a contact state, that is, the circuit breaker maintains a closed state. When the first abutting surface 110 and the second abutting surface 120 are turned from the abutting state to the disengaging state (as shown in fig. 7-8, fig. 8 is a diagram of fig. 7 in which the portion of the second transmission member 12 except the transmission portion 13 is hidden), as the acting force between the first abutting surface 110 and the second abutting surface 120 disappears, the force balance between the first transmission member 11 and the second transmission member 12 is broken, the second transmission member 12 rotates under the elastic force of the first elastic member 14, so that the first electrical contact 121 and the second electrical contact 122 are separated, specifically, the elastic force acting point of the first elastic member 14 is between the first electrical contact 121 and the main shaft 10, and when the second transmission member 12 rotates around the main shaft 10, the end provided with the first electrical contact 121 moves away from the second electrical contact 122, the first electrical contact 121 and the second electrical contact 122 are separated, the circuit is cut off, and the opening of the circuit breaker is realized. The first electrical contact 121 and the second electrical contact 122 may be separated by driving the first transmission member 11 to rotate by an external force, that is, the first transmission member 11 rotates when receiving the external force to separate the first electrical contact 121 and the second electrical contact 122.

In a possible implementation manner, in order to make the contact between the first electrical contact 121 and the second electrical contact 122 more stable, as shown in fig. 5, the second transmission member 12 includes a connecting rod 123 and a movable contact 124, the movable contact 124 is rotatably connected to the connecting rod 123, specifically, a rotating shaft 1230 is disposed on the connecting rod 123, the movable contact 124 is rotatably connected to the connecting rod 123 through the rotating shaft 1230, the transmission part 13 is disposed at one end of the connecting rod 123, the first electrical contact 121 is disposed on the movable contact 124, a first stop surface 1231 is disposed on the connecting rod 123, a second stop surface 1241 matched with the first stop surface 1231 is disposed on the movable contact 124, the elastic force of the first elastic member 14 acts on the movable contact 124, and the rotating shaft 1230 is disposed between the elastic force acting point of the first elastic member 14 and the first electrical contact 121, in this way, when the first electrical contact 121 and the second electrical contact 122 are in contact with each other, under the elastic force of the first elastic element 14, the end of the movable contact 124, where the first electrical contact 121 is disposed, tends to rotate in the direction of the second electrical contact 122, so that the first electrical contact 121 and the second electrical contact 122 are in more reliable contact. After the first abutting surface 110 and the second abutting surface 120 are converted from the abutting state to the disengaging state, the connecting rod 123 rotates under the elastic force of the first elastic member 14 and the action force of the second electrical contact 122 on the first electrical contact 121, and simultaneously the movable contact 124 rotates around the rotating shaft 1230 under the elastic force of the first elastic member 14, when the movable contact 124 rotates around the rotating shaft 1230 for a certain angle, the first stop surface 1231 contacts with the second stop surface 1241, so that the movable contact 124 can not rotate around the rotating shaft 1230 any more, and at this time, the connecting rod 123 and the movable contact 124 integrally rotate (as shown in fig. 7), so as to separate the first electrical contact 121 and the second electrical contact 122.

The transmission portion 13 is connected to the operating element 200, the operating element 200 includes a switching-on position and a switching-off position (as shown in fig. 5 and 12, the operating element 200 is in the switching-on position in fig. 5, and the operating element 200 is in the switching-off position in fig. 12), when the first contact surface 110 and the second contact surface 120 are in contact and the first electrical contact 121 and the second electrical contact 122 are in contact, the operating element 200 is in the switching-on position, and it should be noted that, at this time, the first transmission member 11 and the second transmission member 12 are kept relatively stationary due to the combined action of the acting force between the operating element 200 and the transmission portion 13, the acting force between the first contact surface 110 and the second contact surface 120, the acting force between the first electrical contact 121 and the second electrical contact 122, and the elastic force of the first elastic member 14, the operating element 200 is also held stationary relative to the first transmission part 11 and the second transmission part 12, so that the first electrical contact 121 and the second electrical contact 122 are held in contact, while the operating element 200 is held in the closed position. When the brake is required to be opened, the operating element 200 is operated to move the operating element 200 to the brake opening position, and in the process that the operating element 200 moves to the brake opening position, the transmission part 13 is driven to move, and the second transmission piece 12 and the transmission part 13 move together, so that the first electric contact 121 and the second electric contact 122 are separated, and the brake opening is realized. When the opening is performed by operating the operating element 200, the first contact surface 110 and the second contact surface 120 maintain the contact state.

Specifically, as shown in fig. 14 (in fig. 14, the portion of the second transmission member 11 excluding the transmission portion 13 is hidden), the transmission portion 13 is connected to the operating member 200 through a connecting rod 136, both ends of the connecting rod 136 are respectively rotatably connected with the transmission part 13 and the operating member 200, the transmission part 13 may be provided with a first hole for receiving one end of the connecting rod, the operation member 200 may be provided with a second hole for receiving the other end of the connecting rod, both ends of the connecting rod may rotate in the first hole and the second hole, respectively, in the process of operating the operating member 200 to move to the open position, the operating member 200 rotates around a fixed shaft, the connecting rod 136 follows the movement of the second hole to move the transmission part 13, meanwhile, the rotation of the connecting rod 136 in the first hole and the second hole can prevent the operating part 200 from being stuck in the process of driving the transmission part 13.

Further, in the present embodiment, in order to reduce the operating force of the operating member 200 driving the transmission member 13, the distance from the first electrical contact 121 on the movable contact 124 to the rotating shaft 1230 is equal to the distance from the acting point of the first elastic member 14 on the movable contact 124 to the rotating shaft 1230.

In a possible implementation manner, the switching-off and switching-on executing mechanism 400 includes an internal driving part, so that the switching-off and switching-on executing mechanism 400 supports automatic switching-off of the circuit breaker, specifically, automatic switching-off of the circuit breaker refers to that switching-off is realized by means of the action of the circuit breaker itself without manually operating a component of the circuit breaker. As shown in fig. 9, the switching-closing actuator 400 further includes an internal driving element 15, where the internal driving element 15 is configured to drive the first transmission element 11 to rotate, so that the first abutting surface 110 and the second abutting surface 120 are converted from the abutting state to the disengaging state, and the internal driving element 15 drives the first transmission element 11 to rotate when a short circuit, an overload, or the like occurs in a circuit, or, in other situations requiring switching-off, the circuit breaker receives an external instruction and then controls the internal driving element 15 to drive the first transmission element 11 to rotate.

In a possible implementation manner, the internal driving member 15 includes a power member 151 and a rotating member 152, when the first transmission member 11 is driven to rotate, the power member 151 provides power to enable the rotating member 152 to collide with the first transmission member 11 to rotate, a direction of a collision force of the rotating member 152 on the first transmission member 11 is a direction away from the second electrical contact 122 to enable the first abutting surface 110 and the second abutting surface 120 to be separated, specifically, the power member 151 may be an electromagnetic system including a coil winding, an electromagnetic torque is generated after the coil winding is conducted to provide a suction force for adsorbing the rotating member 152, a return elastic member is disposed on the rotating member 152, and when the opening is required, the power member 151 generates an electromagnetic torque greater than a counter torque of the armature return elastic member, so that two ends of the rotating member 152 rotate in a direction shown by an arrow in fig. 9 to collide with the first transmission member 152 11. After the rotating part 152 drives the opening actuating mechanism to complete opening, the power part 151 no longer provides power, and the rotating part 152 resets under the action of the resetting elastic part, so that the rotating part 152 can realize the next opening driving. Of course, the power element 151 may be another element capable of driving the rotation element 152 to rotate.

In a possible implementation manner, a first collision portion 152a and a second collision portion 152b are disposed on the rotating member 152, an included angle is formed between the first collision portion 152a and the second collision portion 152b, a first protrusion 11a and a second protrusion 11b are disposed on the first transmission member 11, the first protrusion 11a and the first collision portion 152a are disposed correspondingly, the second protrusion 11b and the second collision portion 152b are disposed correspondingly, when the first transmission member 11 is driven to rotate to realize opening, the first collision portion 152a first contacts with the first protrusion 11a (as shown in fig. 10) to realize a first collision on the first transmission member 11, the first transmission member 11 starts to rotate under the action of a collision force, the first abutting surface 110 and the second abutting surface 120 are converted from an abutting state to a disengaging state, and the distance from the first collision portion 152a to the rotating shaft of the rotating member 152 is smaller than the distance from the second collision portion 152b The distance from the rotating shaft of the rotating member 152 to the rotating shaft is greater than the collision force from the first collision portion 152a to the first transmission member 11 when the rotating member 152 rotates, the distance from the first protrusion 11a to the main shaft 10 is greater than the distance from the second protrusion 11b to the main shaft 10, the moment generated by the collision force from the first collision portion 152a to the first protrusion 11a and driving the first transmission member 11 to rotate is greater, so that the first abutting surface 110 and the second abutting surface 120 can be reliably separated, and after the first abutting surface 110 and the second abutting surface 120 are separated, the second transmission member 12 starts to rotate under the elastic force of the first elastic member 14 and drives the first electrical contact 121 and the second electrical contact 122 to be separated. Further, after the first collision portion 152a collides with the first protrusion 11a, the second collision portion 152b contacts the second protrusion 11b (as shown in fig. 11) to realize a second collision on the first transmission member 11, the first transmission member 11 is provided with a third protrusion 11c, at this time, since the second collision portion 152b collides with the second protrusion 11b, the first contact surface 110 and the second contact surface 120 are already separated by the collision action of the first collision portion 152a and the first protrusion 11a, the first transmission member 11 is in a free state, the first transmission member 11 can accelerate to rotate under the kinetic energy of the collision, the third protrusion 11c provided on the first transmission member 11 can collide with the second transmission member 12, the second transmission member 12 is under the elastic force of the second transmission member 12 under the elastic force of the first elastic member 14, the third protrusion 11c is also subjected to the impact force, so that the rotation speed of the second transmission member 12 is increased, the separation speed of the first electric contact 121 and the second electric contact 122 is increased, the staying time of an arc generated in the separation process of the first electric contact 121 and the second electric contact 122 between the electric contacts is reduced, the short-circuit breaking capacity of the circuit breaker is improved, and the service life of the circuit breaker is prolonged.

Meanwhile, since the distance from the first collision portion 152a to the rotation axis of the rotation member 152 is smaller than the distance from the second collision portion 152b to the rotation axis of the rotation member 152, the stroke of the second collision portion 152b is larger than the stroke of the first collision portion 152a, and therefore, the stroke of the third protrusion 11c generated by the collision of the second collision portion 152b with the second protrusion 11b is larger than the stroke of the third protrusion 11c generated by the collision of the first collision portion 151a with the first protrusion 11a, and only the first collision portion 152a is provided with respect to the rotation member 152, in this embodiment, the second collision portion 152b is provided to enable the third protrusion 11c to generate a larger movement. The opening distance of the first electrical contact 121 and the second electrical contact 122 is larger, and the sectional current limiting effect of the circuit breaker is better. It should be noted that, in the case that the connecting rod 123 and the movable contact 124 are provided on the second transmission member 12, when the third protrusion 11c collides with the second transmission member 12, the first stop surface 1231 provided on the connecting rod 123 and the second stop surface 1241 provided on the movable contact 124 are already contacted, that is, the connecting rod 123 and the movable contact 124 integrally rotate at this time, so that the movable contact 124 and the connecting rod 123 do not relatively rotate after the third protrusion 11c collides.

Further, in order to switch the breaker from the open state to the closed state by operating the operating element 200, after the opening and closing actuator 400 opens, the operating element 200 is in the open position. When the brake opening operation is performed by operating the operating element 200, the operating element 200 is moved to the brake opening position, and when the brake opening operation is performed by the internal driving element 15, after the first abutting surface 110 and the second abutting surface 120 are converted from the abutting state to the disengaging state, the transmission part 13 moves along with the second transmission element 12 so that the operating element 200 reaches the brake closing position.

The switching actuator 400 includes a second elastic member 18, and when the internal driving member 15 is used to perform switching, after the first abutting surface 110 and the second abutting surface 120 are switched from the abutting state to the disengaged state, the elastic force of the second elastic member 18 acts on the first transmission member 11 to cause the first abutting surface 110 and the second abutting surface 120 to abut again, so that the first abutting surface 110 and the second abutting surface 120 return to the switching state while the abutting state is maintained. Specifically, the second elastic element 18 is fixedly disposed, the second elastic element 18 may be fixed to the circuit breaker or the main shaft, and the second elastic element 18 may be a spring, an elastic sheet, or the like. Fig. 12 to 13 illustrate an embodiment when the second elastic member 18 is a spring, as shown in fig. 15, the elastic portion of the second elastic member 18 does not contact the first transmission member 11 when the first abutting surface 110 and the second abutting surface 120 abut, after the first transmission member 11 rotates to make the first abutting surface 110 and the second abutting surface 120 change from the abutting state to the disengaged state, the first transmission member 11 continues to rotate, at the same time, the second transmission member 12 drives the transmission portion 13 to move, the first transmission member 11 contacts the second elastic member 18 after rotating to a certain angle, the rotation is limited, after the second transmission member 12 rotates to a certain angle, the transmission portion 13 contacts the first transmission member 11 again, the elastic force of the second elastic member 18 acts on the first transmission member 11, the frictional force between the first abutting surface 110 and the second abutting surface 120 is overcome, so that the first abutting surface 110 and the second abutting surface 120 abut again (as shown in fig. 12 to 13, fig. 13 is a view in which the portion of the second transmission member 12 in fig. 12 except the transmission portion 13 is hidden). The second transmission member 12 is provided with a third stop surface 125, when the first abutting surface 110 and the second abutting surface 120 abut against each other again, the third stop surface 125 contacts with a limiting structure arranged on the circuit breaker, so that the second transmission member 12 cannot rotate continuously, the first transmission member 11, the transmission portion 13 and the second transmission member 12 keep relatively still again, and the first electrical contact 121 and the second electrical contact 122 are kept in a separated state. At this time, the first transmission member 11 and the second transmission member 12 may rotate around the main shaft 10 as a whole, and when the switch is closed, a driving force is applied to rotate the first transmission member 11 and the second transmission member 12 as a whole until the first electrical contact 121 and the second electrical contact, so that the switch is closed. When the operating element 200 is provided, after the first abutting surface 110 and the second abutting surface 120 abut against each other again, the operating element 200 may be operated to close the switch, and when the switch is closed, the operating element 200 moves from the open position to the closed position to drive the transmission part 13 to move, and the first transmission member 11 rotates together with the second transmission member 12 due to the abutting force of the first abutting surface 110 and the second abutting surface 120, so that the first electrical contact 121 and the second electrical contact 122 contact each other, and the switch is closed. After closing, the switching-closing actuator 400 returns to the closing state, that is, the switching-closing actuator 400 maintains balance until the operating element 200 is operated or the first transmission element 11 rotates, so that the switching-closing actuator 400 is unbalanced and performs a switching-off operation.
