As shown in fig. 1 and 2, when the circuit breaker body 2 needs to be switched on, the manager presses down the first wireless signal transmission button S1 of the portable wireless transmission mechanism a7, so that the wireless transmission mechanism a7 transmits the first path of wireless closing signal, and stops transmitting the wireless closing signal after releasing the hand; after the wireless receiving circuit module a2 of the wireless receiving mechanism receives the first path of wireless closing signal, pin 3 of the wireless receiving circuit module a2 outputs a high level, and the high level is subjected to voltage reduction and current limitation by the resistor R1 and enters the base of the NPN triode Q1, so that the NPN triode Q1 is turned on (power amplification) and the collector outputs a low level, and enters the negative power input end of the relay J1; because the positive power input end and the control power input end of the relay J1 are communicated with the pin 3 of the switch power supply A1, the normally open contact end of the relay J1 is connected with the pin 3 of the trigger signal input end of the time control switches A3 and A4 (the

pins

2 and 4 of the time control switches A3 and A4 are communicated with the pin 4 of the switch power supply A1, and the pin 1 is communicated with the pin 3 of the switch power supply A1), the relay J1 can be electrically attracted at the moment, the control power input end and the normally open contact end are closed, and the pin 3 of the time control switches A3 and A4 can be input with a high level trigger signal; at this time, because the time control switch A3 is in an electrified working state, under the action of the time of outputting the power supply after the internal circuit of the time control switch A3, the 5 and 4 pins of the time control switch A3 set by production technicians and the 3 pin is input to trigger a high level signal every time, the 5 and 4 pins of the time control switch A3 can output 5 seconds of power supply to enter the two ends of the power supply input of the relay J2, and then the relay J2 is electrified to attract the two control power supply input ends (the two control power supply input ends are respectively communicated with the 3 and 4 pins of the switch power supply a 1) and the two normally open contact ends are respectively closed. Because two normally open contact ends of the relay J2 are respectively connected with two input ends of a positive and negative pole power supply of the first set of motor reducing mechanism M1 through leads, the motor reducing mechanism M1 can work for 5 seconds after a manager presses the first wireless signal transmitting key S1 of the wireless transmitting mechanism A7 each time. After the first set of motor speed reducing mechanism M1 works by power, the power output by the motor is reduced by the multi-stage gear speed reducing mechanism in the left end of the shell to increase torque, and then the power is output from the power output shaft and the power output shaft to clockwise synchronously drive the winding drum 61 of the first set of motor speed reducing mechanism M1 (the outer circumference of the winding drum is about 1cm after the pulling rope wound by the winding drum is wound at the outer end of the winding drum) to clockwise rotate for 5 turns (within 5 seconds); in the first two halves of the rotation of the winding drum 61, the pull rope 63 connected with the front upper end of the opening and closing handle of the circuit breaker body can be wound and tensioned (the front pull rope and the front upper end of the opening and closing handle of the circuit breaker body have 2.5cm length allowance), the winding drum 61 can pull the opening and closing handle 22 in the downward opening state to move upwards by about 2.5cm within the last 2.5 seconds of the continuous rotation, so that under the action of an internal mechanism of the circuit breaker body 2, the circuit breaker body 2 can be in the closing state (the opening and closing handle 22 of the circuit breaker body is switched from the downward opening state to the upward closing state, the movement stroke of the front end is about 2.5cm, when the relay J1 is electrified to close the control power supply input end and the normally open contact end, and when the 3 feet of the time control switch A3 are input with a high-level trigger signal, the 3 feet of the time switch A4 are also input with a high-level trigger signal, the time switch A4 is set in an internal circuit and 5 and 4 feet of the, Under the action of power supply output time after a 3-pin input triggering high-level signal every time, 5 pins and 4 pins of the time control switch A4 can output power supply for 2.5 seconds after 5 seconds of interval and enter two power supply input ends of the relay J6, so that the relay J6 is electrified to attract two control power supply input ends and two normally open contact ends of the relay J6 to be respectively closed. Because two normally open contact ends of the relay J6 (two control power supply input ends are respectively communicated with the

pins

3 and 4 of the switch power supply A1) are respectively connected with two ends of the negative and positive connection power supply input end of the first set of motor reducing mechanism M1 through leads, after a manager presses the first wireless signal transmission key S1 of the wireless transmission mechanism A7 every time, the interval is 5 seconds, and the motor reducing mechanism M1 can be electrified and work for 2.5 seconds again. After the first set of motor speed reducing mechanism M1 works by power, the power output by the motor is reduced by the multi-stage gear speed reducing mechanism in the left end of the shell to increase torque, and then the power is output from the power output shaft and the power output shaft to drive the winding drum 61 of the first set of motor speed reducing mechanism M1 (the pulling rope wound by the winding drum is wound around the outer end of the winding drum with the outer circumference of about 1cm) to rotate counterclockwise for 2.5 turns (within 2.5 seconds); the winding drum 61 rotates anticlockwise for 2.5 seconds, rotate anticlockwise for 2.5 circles, the stay cord 63 of the winding drum like this, no longer be in the taut state between the on-off operating handle 22 of circuit breaker body, the winding drum 61 unreels, then, stay cord and the preceding upper end of circuit breaker body on-off operating handle have had 2.5cm length surplus again at this moment, do benefit to the separating brake operation of follow-up circuit breaker body, when the on-off operating handle of circuit breaker body was down, the stay cord 63 of the winding drum of circuit breaker body upper end can not lead to the fact the hindrance to the fact the branch on-off operating handle is down. Under the effect of the internal elastic fixing mechanism of the circuit breaker body and the like, even if the winding drum loosens the pull rope 63 after the circuit breaker body is in a closing state, as long as the short circuit, the overload and other faults do not occur, the opening and closing operation handle of the circuit breaker body does not move downwards under the action of external force, and therefore the circuit breaker body cannot move downwards and further is prevented from being opened by mistake.

As shown in fig. 1 and 2, when the circuit breaker body 2 needs to be opened, the manager presses the second wireless signal transmitting button S2 of the portable wireless transmitting mechanism a7, so that the wireless transmitting mechanism a7 transmits a second wireless closing signal, and stops transmitting the wireless closing signal after releasing the hands; after the wireless receiving circuit module a2 of the wireless receiving mechanism receives the second wireless closing signal, pin 4 of the wireless receiving circuit module a2 outputs a high level, and the high level is subjected to voltage reduction and current limitation by the resistor R2 and enters the base of the NPN triode Q2, so that the NPN triode Q2 (power amplification) is conducted, and the collector of the NPN triode Q2 outputs a low level and enters the negative power input end of the relay J3; because the positive power input end and the control power input end of the relay J3 are communicated with the 3 pins of the switch power supply A1, the normally open contact end of the relay J3 is connected with the 3 pins of the trigger signal input ends of the time control switches A5 and A6 (the 2 and 4 pins of the time control switches A5 and A6 are communicated with the 4 pins of the switch power supply A1, and the 1 pin is communicated with the 3 pins of the switch power supply A1), the relay J3 can be electrically attracted at the moment, the control power input end and the normally open contact end are closed, and the 3 pins of the time control switches A5 and A6 can be input with high level trigger signals; at this time, because the time control switch a5 is in an electrified working state, under the action of the time of outputting the power supply after the internal circuit of the time control switch a5, the 5 and 4 pins of the time control switch a5 set by production technicians and the 3 pin is input to trigger a high level signal every time, the 5 and 4 pins of the time control switch a5 can output 5 seconds of power supply to enter the two ends of the power supply input of the relay J5, and then the relay J5 is electrified to attract the two control power supply input ends (the two control power supply input ends are respectively communicated with the 3 and 4 pins of the switch power supply a 1) and the two normally open contact ends are respectively closed. Because two normally open contact ends of the relay J5 are respectively connected with two input ends of a positive and negative pole power supply of the second set of motor reducing mechanism M2 through leads, the motor reducing mechanism M2 can work for 5 seconds after a manager presses the second wireless signal transmitting key S2 of the wireless transmitting mechanism A7 each time. After the second set of motor speed reducing mechanism M2 works by power, the power output by the motor is reduced by the multi-stage gear speed reducing mechanism in the left end of the shell to increase torque, and then the power output shaft outputs power and the power output shaft clockwise synchronously drive the winding drum 61 of the second set of motor speed reducing mechanism M2 (the outer circumference of the winding drum is about 1cm after the pulling rope wound by the winding drum is wound at the outer end of the winding drum) to clockwise rotate for 5 turns (within 5 seconds); in the first two and a half circles of the winding drum 61 before rotating, the pull rope connected with the front lower end of the breaker body opening and closing handle 22 can be wound and tensioned (the front pull rope and the front lower end of the breaker body opening and closing handle have 2.5cm length allowance), the winding drum 61 can pull the opening and closing handle 22 which is in the upward closing state before within the last 2.5 seconds of continuous rotation to move downwards by about 2.5cm, and then under the action of the internal mechanism of the breaker body, the breaker body 2 can be in the opening state (the opening and closing handle of the breaker body is converted from the upward closing state to the downward opening state, and the movement stroke of the front end is about 2.5 cm). When the relay J3 is powered on to close the control power supply input end and the normally open contact end of the relay J3, and a high-level trigger signal is input into the pin 3 of the time control switch A5, a high-level trigger signal is also input into the pin 3 of the time control switch A6, the time control switch A6 outputs power supply into the two ends of the power supply input end of the relay J4 at an interval of 2.5 seconds after the internal circuit of the time control switch A6 and the pin 5 and the pin 4 of the time control switch A6 are input with the trigger high-level signal every time and then under the action of power supply time, so that the relay J4 is powered on to close the two control power supply input ends (the two control power supply input ends are respectively communicated with the pin 3 and the pin 4 of the switch power supply A1) and the two normally open contact ends of the relay J4. Because two normally open contact ends of the relay J4 are respectively connected with two negative and positive connection power input ends of the second set of motor reducing mechanism M2 through leads, after a manager presses a second wireless signal transmission key S2 of the wireless transmission mechanism A7 every time and at an interval of 5 seconds, the motor reducing mechanism M2 can be electrified again to work for 2.5 seconds. After the second motor speed reducing mechanism M2 works by power, the power output by the motor is reduced by the multi-stage gear speed reducing mechanism in the left end of the shell to increase the torque, and then the power is output by the power output shaft and the power output shaft to anticlockwise synchronously drive the winding drum 61 (the outer circumference of the winding drum is about 1cm after the pulling rope wound by the winding drum is wound at the outer end of the winding drum) of the second motor speed reducing mechanism M2 to anticlockwise rotate for 2.5 circles (within 2.5 seconds); the winding drum 61 rotates anticlockwise for 2.5 seconds, rotates anticlockwise for 2.5 circles, so the pull rope 63 of the winding drum before, the opening and closing handle of the circuit breaker body is no longer in a tensioning state, the winding drum 61 unreels, then, the pull rope and the front lower end of the opening and closing handle 22 of the circuit breaker body have 2.5cm length allowance again at the moment, the follow-up closing operation of the circuit breaker body 22 is facilitated, when the opening and closing handle 22 of the circuit breaker body goes upward, the pull rope 63 of the winding drum at the lower end of the circuit breaker body cannot cause obstruction to the upward movement of the opening and closing handle 22. Under the effect of the inside elastic fixing mechanism of the circuit breaker body and the like, even if the winding drum loosens the pull rope 63 after the circuit breaker body 22 is in the opening state, the opening and closing handle of the circuit breaker body does not move upwards under the action of external force, and the circuit breaker body cannot move upwards and further leads to mistaken closing. This neotype motor reduction gears M1, M2 power output shaft rotational speed 60 revolutions per minute, because the supply of stable voltage has effectively been guaranteed in the switching regulated power supply A1 power supply, its rotational speed can not change. When the winding drums of the two sets of motor reduction mechanisms M1 and M2 unwind the pull rope 63, the unwinding is only 2.5 seconds and 2.5cm, so that the rewinding of the winding drums to the pull rope 63 cannot be caused due to too much unwinding. Relays J1, J3 are small 5V relays of the pinolen brand having two power inputs, a control power input, a normally open contact end, and a normally closed contact end. Relays J2, J4, J5, J6 are 5V relays of the brand Songle having two power input terminals, two control power input terminals, two normally open contact terminals, two normally closed contact terminals. The resistances of the resistors R1 and R2 are 1K. The model numbers of NPN triodes Q1 and Q2 are 9013. This novel circuit breaker that is applicable to any model specification uses. This novel well stay cord adopts the cotton thread that has certain intensity, nylon line etc, can also adopt the rubber band that has certain intensity as the stay cord, thus, even the extreme condition motor reduction gears rotates the number of turns too much, but because it has elasticity, the divide-shut brake handle makes progress or the pulling is target in place downwards, the continuation motion can not lead to the too much influence to normal work of pulling divide-shut brake handle movement distance because the ductility of rubber band yet (because divide-shut brake handle up-and-down motion drive moment is not big, as long as the rubber band intensity is suitable, can guarantee the upwards or the downstream of pulling divide-shut brake handle under the initial condition).
