Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Circuit breaker, also referred to as automatic air-break switch, can be used to connect and disjunction load circuit, also can be used to the motor controlling infrequently to start.Its function is equivalent to electrical appliance part or whole function summations such as knife switch, overcurrent relay, no-voltage relay, thermal relay and earth leakage protective device, is a kind of important protective device in low-voltage network.
The main contacts of circuit breaker is by manual operation or electric switch-on.After main contacts is closed, main contacts is locked on closing position by free tripping mechanism.
In the present invention's one adopts, driven off by shaft automatic switching on device is made up of circuit breaker and control module.Wherein, circuit breaker has defencive function, can realize overcurrent tripping and overlond trip; Control module is made up of axle, 3.-rotating disk, 4.-boss, 5.-turbine, 6.-scroll bar and control circuit in 1.-stepping motor, 2.-transmission.Adopt axle in transmission to drive circuit breaker to carry out switching on, the synchronism that contact of breaker is closed is better, and in transmission, axle is the Axis Tripod of metal material.
The power source of control module inside of the present invention is stepping motor, can control step motor forward or reverse by circuit, scroll bar and turbine adopt gears meshing to be connected, stepping motor can drive turbine rotation by the scroll bar that axle is installed, rotating disk can be promoted by the boss of two on turbine during turbine rotation, Axis Tripod is fixed on rotating disk, and circuit breaker is driven by the rotation of Axis Tripod.The combined floodgate of on-load switch and operating a switch is controlled by external signal.
Making process: stepping motor is rotated by scroll bar and drives turbine, turbine rotates clockwise and promotes rotating disk by the boss on the left side, and rotating disk rotates clockwise and drives breaker closing by Axis Tripod.When circuit breaker arrives closing position, stepping motor starts to rotate back into position as shown in the figure counterclockwise, does not affect the trip free of circuit breaker.
To operate a switch process: stepping motor is rotated by scroll bar and drives turbine, turbine rotates counterclockwise and promotes rotating disk by the boss on the right, and rotating disk rotates counterclockwise and drives circuit breaker to operate a switch by Axis Tripod.When being operated a switch in position in circuit breaker arrival, stepping motor stops the rotation.
In transmission, axle is the Axis Tripod of metal material, has enough intensity; Stepping motor is opened loop control unit stepping motor part electric impulse signal being changed into angular displacement or displacement of the lines.When non-overload, the rotating speed of motor, the position of stopping only depending on frequency and the umber of pulse of pulse signal, and not by the impact of load variations, when step actuator receives a pulse signal, it rotates a fixing angle with regard to Driving Stepping Motor by the direction of setting, be called " step angle ", its rotation runs step by step with fixing angle.Pilot angle displacement can be carried out by control impuls number, thus reach the object of accurately location; Speed and the acceleration of electric machine rotation can be controlled simultaneously by control impuls frequency, thus reach the object of speed governing; Control circuit is controlled by an input signal, control module can have automatic switching on, prevents from closing a floodgate, and pattern switches, the functions such as state instruction.
The automatic switching on function of the present invention refer to when circuit breaker receive operate a switch or close a floodgate order time, drive axle in transmission to control circuit breaker by step motor control and operate a switch or close a floodgate.
Stepping motor is locked after circuit breaker receives order of operating a switch to prevent combined floodgate from referring to, prevents circuit breaker closing by hand.
Mode of operation of the present invention is divided into manual mode and automatic mode, when circuit breaker is operated in automatic mode, receives when closing a floodgate and operate a switch order and drives circuit breaker to perform combined floodgate and order of operating a switch by stepping motor in control module; In a manual mode, receive stepping motor when operating a switch and drive circuit breaker to operate a switch, when receiving combined floodgate order, circuit breaker is automatic closing not, waits for user's closing by hand in circuit breaker work.
Circuit breaker has status indicator lamp, and during normal work, indicator light colors is green, and with the frequency scintillation of 1Hz, when there is operation irregularity, indicator light is red, long bright.Control signal is the level signal of 0v or 220v.
Embodiment
In the present invention's one adopts, driven off by shaft automatic switching on method is specific as follows:
Making process:
Level signal by 0V saltus step to 220V;
Control module internal mechanism drives Axis Tripod to rotate forward until breaker closing;
Inner switching-on mechanism reversion certain angle, can trip status to make circuit breaker get back to.
To operate a switch process:
Level signal by 220V saltus step to 0V;
Control module internal mechanism drives Axis Tripod to rotate backward certain angle, and circuit breaker is operated a switch;
Now circuit breaker should pass through manual closing operation (anti-closing protective).
Close a floodgate and allow:
In a manual mode, level signal by 0V saltus step to 220V;
Control module internal mechanism drives Axis Tripod to rotate forward certain angle, eliminates anti-closing protective, enters combined floodgate enable state, can closing by hand.
Table 1 is mode of operation explanation
Table 1
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, those of ordinary skill in the field are to be understood that: although can modify to the specific embodiment of the present invention with reference to above-described embodiment or equivalent replacement, these do not depart from any amendment of spirit and scope of the invention or equivalent replacement, are all applying within the right of the present invention awaited the reply.
