Further, as shown in fig. 1-10, the operating system comprises an operating mechanism 2, wherein the operating mechanism 2 is used for being in transmission fit with the moving contact mechanism 5-1, i.e. the operating mechanism 2 is in transmission fit with the moving contact mechanism 5-1. The operating mechanism 2 comprises an energy storage torsion spring 2-0, a bracket 2-8 fixedly arranged (for example, the bracket 2-8 is fixedly connected with a shell structure of the control and protection switch and/or is in limit fit with the shell structure to realize the fixed arrangement of the bracket 2-8), and a transmission rod 2-6 rotatably arranged on the bracket 2-8. The two spring arms of the energy storage torsion spring 2-0 are respectively a transmission arm 2-01 which is rotationally connected with the transmission rod 2-6 and a pivoting arm 2-02 which is rotationally connected with the bracket 2-8, namely the energy storage torsion spring 2-0 comprises two spring arms which are respectively a transmission arm 2-01 and a pivoting arm 2-02, the transmission arm 2-01 is rotationally connected with the transmission rod 2-6, and the pivoting arm 2-02 is rotationally connected with the bracket 2-8.
When the operating mechanism 2 is switched on (i.e. when the operating mechanism 2 performs switching-on operation), the transmission rod 2-6 rotates along the direction d2 to enable the moving contact mechanism 5-1 to move to a closed position and drive the transmission arm 2-01 to move to a position p1 to enable the energy storage torsion spring 2-0 to store energy, i.e. when the operating mechanism 2 is switched on, the transmission rod 2-6 rotates along the direction d2 to enable the moving contact mechanism 5-1 to move to a closed position to be closed with the fixed contact 5-2, meanwhile, the transmission rod 2-6 drives the transmission arm 2-01 to move to the position p1 to enable the energy storage torsion spring 2-0 to store energy, and the position p1 of the transmission arm 2-01 corresponds to an energy storage state of the energy storage torsion spring 2-0.
When the operating mechanism 2 is switched off (namely, when the operating mechanism 2 performs switching-off operation), the energy storage torsion spring 2-0 releases energy and is used for driving the transmission rod 2-6 to rotate along the direction d1 through the transmission arm 2-01 so as to drive the movable contact mechanism 5-1 to move to the switching-off position, and simultaneously the transmission arm 2-01 moves to the position p2, namely, when the operating mechanism 2 is switched on, the energy storage torsion spring 2-0 releases energy and drives the transmission rod 2-6 to rotate along the direction d1 through the transmission arm 2-01, and simultaneously the transmission rod 2-6 drives the movable contact mechanism 5-1 to move to the switching-off position so as to be disconnected with the fixed contact 5-2, and simultaneously the transmission arm 2-01 moves to the position p2, and the position p2 of the transmission arm 2-01 corresponds to the energy storage torsion spring 2-0, and the direction d1 and the direction d2 are opposite to each other.

Further, when the operating mechanism 2 is switched on, the contact spring 5-3 presses the support 5-12 of the moving contact mechanism 5-1 to drive the moving contact mechanism 5-1 to move to the closed position linearly to be closed with the fixed contact 5-2, and when the operating mechanism 2 is switched off, the transmission rod 2-6 presses the support 5-12 of the moving contact mechanism 5-1 to drive the moving contact mechanism 5-1 to move to the open position to be disconnected with the fixed contact 5-2, and meanwhile, the support 5-12 enables the contact spring 5-3 to store energy. Further, the support 2-8 may be an independent structure, i.e. the support 2-8 is a structure independent of the housing structure of the control and protection switch and other parts of the present embodiment, or the support 2-8 is implemented by the housing structure of the control and protection switch of the present embodiment, i.e. a part of the housing structure of the control and protection switch of the present embodiment serves as the support 2-8. Further, as shown in fig. 7-8, the direction d1 is clockwise, and the direction d2 is counterclockwise;
Further, as shown in fig. 7-8, the operating system further comprises a handle 1 rotatably arranged, the operating mechanism 2 is realized by the prior art, for example, the operating mechanism 2 further comprises a transmission part 2-1, a front connecting rod 2-2, a locking part 2-3, a trip part 2-4, a rear connecting rod 2-5 and a trip part spring 2-7, the transmission part 2-1 and the trip part 2-4 are respectively rotatably arranged on a bracket 2-8, the handle 1 is in transmission fit with the transmission part 2-1 and used for driving the transmission part to rotate, the transmission part 2-1 is in transmission connection with the locking part 2-3 through the front connecting rod 2-2, the locking part 2-3 is in transmission connection with the transmission rod 2-6 and used for driving the rotation of the locking part 2-3 through the rear connecting rod 2-5, the operating mechanism 2 keeps in snap fit with the trip part 2-4 in a closing state, the locking part 2-3 is in release of the trip part 2-4 in a separating state, and the trip part spring 2-7 acts on the trip part 2-4 for resetting the trip part to an initial position and keeping the initial position. Further, the rotating shaft direction of the transmission part 2-1, the jump fastener 2-4 and the transmission rod 2-6 is the same as the direction d3, the support 2-8 comprises two support side plates which are oppositely arranged side by side along the direction d3, the transmission part 2-1, the front connecting rod 2-2, the jump fastener 2-3, the jump fastener 2-4, the rear connecting rod 2-5 and the transmission rod 2-6 are all positioned between the two side plates, and the rotating shaft direction of the handle 1 is the same as the direction d 4. The operation of the operating mechanism 2 is the same as in the prior art and will not be described here.
Further, as shown in fig. 1-2, 7-8, the operating mechanism 2 is arranged side by side with the contact system 5 along the direction d 4.
Further, as shown in fig. 1-6, the operating system further includes a control module 8, a breaking electromagnet 3 for being driven by the control module 8 to act, a push rod 7 linked with a driving arm 2-01 of the energy storage torsion spring 2-0, and a control switch 14 connected in series in a power circuit of the control module 8, wherein the breaking electromagnet 3 acts to drive the moving contact mechanism 5-1 to move to an off position, that is, the control module 8 receives a control signal to drive the breaking electromagnet 3 to act, and then the breaking electromagnet 3 drives the moving contact mechanism 5-1 to move to the off position and disconnect from the fixed contact 5-2, the driving arm 2-01 moves from the position p2 to the position p1 (that is, when the operating mechanism 2 is switched on), the push rod 7 triggers the control switch 14 to switch on the power circuit of the control module 8, that is, when the operating mechanism 2 is switched off, the driving arm 2-01 moves from the position p2 to the position p1, the push rod 7 triggers the control switch 14 to switch on, and the power circuit of the control module 8 is switched off, and the driving arm 2-01 moves from the position p2 to the position 7 to the off position, that the control switch 14 is controlled to resume the on state. The linkage of the push rod 7 and the transmission arm 2-01 means that the push rod 7 acts due to the action of the transmission arm 2-01, and the push rod 7 only moves when the transmission arm 2-01 moves, otherwise, the push rod 7 and the transmission arm 2-01 are relatively stationary. The term "during the movement of the driving arm 2-01 from the position p2 to the position p 1" refers to the whole process that the driving arm 2-01 starts to move from the position p2 to the position p1, so that the moment when the push rod 7 triggers the control switch 14 is the moment when the driving arm 2-01 moves to the position p1 or the moment when the driving arm 2-01 starts from the position p2 and moves to the position p1 before, and in this embodiment, the moment when the push rod 7 triggers the control switch 14 can be slightly earlier than the moment when the driving arm 2-01 moves to the position p1, thereby ensuring that the push rod 7 can trigger the control switch 14. The "control signal" received by the control module 8 may be a remote brake-off signal or a fault signal, including a residual current fault signal and an over-current fault signal.
The push rod 7 is matched with the operating mechanism 2, when the operating mechanism 2 is switched off, the control switch 14 is triggered to disconnect the power supply circuit of the control module 8, the situation that the control module 8 is still continuously electrified to be damaged after the control and protection switch of the embodiment is switched off is avoided, the transmission arm 2-01 of the energy storage torsion spring 2-0 is matched with the push rod 7 to trigger the control switch 14, the transmission structure is simple, the transmission path is short, and the transmission process is reliable.
As another embodiment of the operating system, the difference between the operating system and the present embodiment is that the push rod 7 triggers the control switch 14 to turn off the power circuit of the control module 8 in the process of moving the driving arm 2-01 from the position p1 to the position p2 (i.e. when the operating mechanism 2 is switched off), that is, the control switch 14 is normally closed, when the operating mechanism 2 is switched off, the driving arm 2-01 moves from the position p1 to the position p2, the push rod 7 triggers the control switch 14 to be switched off so as to turn off the power circuit of the control module 8, when the operating mechanism 2 is switched on, the driving arm 2-01 moves from the position p2 to the position p1, and the push rod 7 is far away so as to release the control switch 14, so that the control switch 14 is restored to the on state.
Further, as shown in fig. 9, the control module 8 includes a triac. Or as shown in fig. 10, the control module 8 comprises an intermediate relay.
Further, as shown in fig. 2-6, the control switch 14 is a micro switch. Specifically, the micro-switch comprises an operation rod 14-0, and the push rod 7 presses the operation rod 14-0 to trigger the micro-switch to switch the working state.
Further, as shown in fig. 2-6, the control switch 14 is arranged on the support of the breaking electromagnet 3.
Further, as shown in fig. 3-6, the operating system further includes a push rod reset member 15 in transmission fit with the push rod 7, when the driving arm 2-01 moves from the position p2 to the position p1, that is, when the operating mechanism 2 is switched on, the push rod 7 enables the push rod reset member 15 to store energy, that is, when the operating mechanism 2 is switched on, the driving arm 2-01 needs to overcome the acting force of the push rod reset member 15 to drive the push rod 7 to move, when the driving arm 2-01 moves from the position p1 to the position p2, that is, when the operating mechanism 2 is switched off, the driving arm 2-01 avoids the push rod 7, that is, when the operating mechanism 2 is switched off, the driving arm 2-01 continues to avoid the push rod 7 without applying the acting force to the driving arm, and the push rod 7 can reset under the action of the push rod reset member 15.
The push rod resetting piece 15 can drive the push rod 7 to reset, and can apply acting force to the transmission arm 2-01 through the push rod 7, so that the energy release process of the energy storage torsion spring 2-0 is accelerated, the rotation speed of the transmission rod 2-6 is accelerated, the disconnection speed of the movable contact mechanism 5-1 and the fixed contact 5-2 is improved, and the breaking capacity of the contact system 5 is improved.
