The present invention detects whether the auxiliary circuit / main circuit is opened / closed in place through the first micro switch group 33 and the second micro switch group 32, and controls the electric drive component 28 to drive or stop according to this signal, and detects the opening / closing state of the auxiliary circuit / main circuit through the third micro switch group 34 and the fourth micro switch group 35, and transmits this signal to the external output communication port on the control board 31, which is used to feedback the opening / closing state of the auxiliary circuit / main circuit to the outside; The control unit 30 also includes a supercapacitor component (not shown in the figure). Under extreme conditions where the power is completely cut off outside the switch, the discharge of the supercapacitor can provide the electric operating mechanism with the power required to open the switch.

[0034] The specific control principle of the switch of the present invention is: first, the drive shaft 22 is in the initial position, at which time the main circuit and the auxiliary circuit are in the open state, that is, the current switch is in the open mode, such as Figures 12-13As shown; the driving shaft 22 is rotated clockwise by manual operation or electric control. At this time, the fan-shaped limit block 221 slides in the fan-shaped clutch groove 2311, and the first side shaft 254 slides in the first arc groove 223. When the fan-shaped limit block 221 hits the side wall of the protrusion 2312, the driving shaft 22 drives the active gear 231 to rotate clockwise. At this time, the first side shaft 254 hits the side wall of the first arc groove 223. The driving shaft 22 also drives the first rotating frame 251 to rotate clockwise, compressing the first energy storage spring 274, and then the other end of the first side shaft 254 slides in the second arc groove 2531. When the first energy storage spring 274 is compressed past the dead point, the elastic force is released to push the first rotating frame 251 to rotate rapidly clockwise, and the other end of the first side shaft 254 hits the second arc groove 2531 inner wall, thereby pushing the auxiliary circuit driving turntable 253 to rotate rapidly clockwise, and the auxiliary circuit driving turntable 253 drives the auxiliary circuit moving contact shaft 151 to rotate rapidly clockwise, so that the auxiliary circuit moving contact piece 152 quickly abuts against the auxiliary circuit static contact piece 133, so that the auxiliary circuit moving contact assembly 15 and the auxiliary circuit static contact assembly 13 are in contact and closed. At this time, the first arc-shaped limiting hole 2151 and the third arc-shaped limiting hole 2161 simultaneously limit the rotation of the first rotating frame 251. During the process, although the active gear 231 drives the driven gear 232 to rotate counterclockwise, the second side shaft 244 still slides in the third arc-shaped groove 2321, so the second rotating frame 241 does not rotate, and the main circuit is still in the open state. At this time, the auxiliary circuit is in the closed state, and the main circuit is in the open state, that is, the switch is now in the standby mode. Figures 14 and 15As shown; the driving shaft 22 continues to rotate clockwise, pushing the driving gear 231 to drive the driven gear 232 to continue to rotate counterclockwise. When the second side shaft 244 hits the side wall of the third arc groove 2321, the driven gear 232 drives the second rotating frame 241 to rotate counterclockwise, compressing the second energy storage spring 264, and then the other end of the second side shaft 244 slides in the fourth arc groove 2431. When the second energy storage spring 264 is compressed past the dead point, the elastic force is released to push the second rotating frame 241 to rotate counterclockwise rapidly. The other end of the second side shaft 244 hits the side wall of the fourth arc groove 2431, thereby pushing the main circuit driving turntable 243 to rotate counterclockwise rapidly. The moving turntable 243 drives the main circuit moving contact shaft 141 to rotate rapidly counterclockwise, so that the main circuit moving contact piece 142 quickly abuts against the main circuit static contact piece 123, so that the main circuit moving contact assembly 14 and the main circuit static contact assembly 12 are in contact and closed. At this time, the second arc-shaped limiting hole 2152 and the fourth arc-shaped limiting hole 2162 simultaneously limit the rotation of the second rotating frame 241. Although the driving shaft 22 rotates clockwise during the process, the first side shaft 254 slides in the first arc groove 223, so the first rotating frame 251 does not rotate, and the auxiliary circuit is still in the closed state. At this time, the auxiliary circuit is in the closed state, and the main circuit is in the closed state, that is, the switch is now in the transition mode, such as Figures 16 and 17 As shown; at this time, the driving shaft 22 is rotated counterclockwise, and the fan-shaped limit block 221 slides in the fan-shaped clutch groove 2311, and the first side shaft 254 slides in the first arc groove 223. When the first side shaft 254 hits the side wall of the other end of the first arc groove 223, the driving shaft 22 drives the first rotating frame 251 to rotate counterclockwise, compressing the first energy storage spring 274, and then the other end of the first side shaft 254 slides in the second arc groove 2531. When the first energy storage spring 274 is compressed past the dead point, the elastic force is released to push the first rotating frame 251 to rotate counterclockwise rapidly. When the other end of the first side shaft 254 touches the side wall of the second arc groove 2531, it pushes the auxiliary circuit driving turntable 253 to rotate counterclockwise rapidly. The driving turntable 253 of the circuit drives the auxiliary circuit moving contact shaft 151 to rotate rapidly counterclockwise, so that the auxiliary circuit moving contact piece 152 and the auxiliary circuit static contact piece 133 are quickly separated, so that the auxiliary circuit moving contact assembly 15 and the auxiliary circuit static contact assembly 13 are separated and opened. At this time, the first arc-shaped limiting hole 2151 and the third arc-shaped limiting hole 2161 simultaneously limit the rotation of the first rotating frame 251. During the process, although the driving shaft 22 pushes the active gear 231 to drive the driven gear 232 to rotate clockwise, the second side shaft 244 still slides in the third arc-shaped groove 2321, so the second rotating frame 241 does not rotate, and the main circuit is still in the closed state. At this time, the auxiliary circuit is in the open state, and the main circuit is in the closed state, that is, the switch is now in the closed mode. Figures 18 and 19As shown; continue to rotate the driving shaft 22 counterclockwise, the driving shaft 22 pushes the driving gear 231 to drive the driven gear 232 to continue to rotate clockwise, when the second side shaft 244 hits the side wall of the other end of the third arc groove 2321, the driven gear 232 drives the second rotating frame 241 to rotate clockwise, compressing the second energy storage spring 264, and then the other end of the second side shaft 244 slides in the fourth arc groove 2431, when the second energy storage spring 264 is compressed past the dead point, the elastic force is released to push the second rotating frame 241 to rotate rapidly clockwise, the other end of the second side shaft 244 hits the side wall of the fourth arc groove 2431, and then pushes the main circuit driving turntable 243 to rotate rapidly clockwise, and the main circuit driving turntable 243 drives the main circuit moving contact shaft 141 to rotate rapidly clockwise, so that the main circuit moving contact piece 142 and the main circuit static contact piece 1 23 quickly separates, so that the main circuit moving contact assembly 14 is separated and opened from the main circuit static contact assembly 12. At this time, the second arc-shaped limit hole 2152 and the fourth arc-shaped limit hole 2162 simultaneously limit the rotation of the second rotating frame 241. Although the driving shaft 22 rotates counterclockwise during the process, the first side shaft 254 slides in the first arc groove 223, so the first rotating frame 251 does not rotate, and the auxiliary circuit is still in the open state. At this time, the auxiliary circuit is in the open state, and the main circuit is in the open state, that is, the switch is now in the open mode, and the driving shaft 22 returns to the initial position; the present invention is different from the traditional control switch. During the opening and closing process, a preparatory and transitional control mode is set, so that the switch unit can reasonably configure the on and off of the energy storage battery charging and discharging circuit according to the instruction, thereby improving the system operation reliability and reducing the risk of accidents.
