Description
Technical field
The utility model belongs to fault detect field, relates to a kind of arc fault detection device, is specifically related to a kind of arc fault intelligent detection device.
Background technology
Along with the raising of people's living standard, the attention of country to electrical safety, China starts to develop arc fault detection device, so a reliable and secure arc generating device is absolutely necessary, our conventional arcing device major part or manual operation at present, this method can not be taken manpower and is also easy to an electrode damage very much, the movement with stepper motor band moving electrode having carrys out arcing, the shortcoming of this method is that motor speed is too slow, if two electrodes are every must be far away, the close time of electrode is used longlyer, if the speed of motor is fast, easily damages electrode.There is fraction arc generating device to utilize motor and some travel switches to control motor arcing, but the installation of travel switch is inconvenient and number is many, brought very large inconvenience to us, our desirable situation is that two electrodes are separated by when distant, motor fast moving; Two motors are separated by when closer, and motor advances at a slow speed, therefore needs a kind of novel intelligent motor speed changing method.
Utility model content
For the deficiency addressing the above problem, the utility model provides a kind of arc fault intelligent detection device, and object is that the motor that utilizes range sensor to make arc generating device reaches intelligent switch speed and carrys out detection failure electric arc.
For achieving the above object, arc fault intelligent detection device mainly comprises copper rod A, carbon-point B, high precision range sensor module C and D, motor driver, slide block, walking motor, screw mandrel, base, fixed block and terminals.High-precision distance sensor device is separately fixed on two electrodes of arc generating device, the control line of high precision range sensor is connected distance signal is issued to single-chip microcomputer with the pin of single-chip microcomputer, single-chip microcomputer is according to the arcing distance writing in advance and the size of range distance, the signal that arcing distance and range sensor transmit, the relation between three judged produces corresponding square-wave signal passes to the driver of stepper motor, the square-wave signal that stepper motor driver produces according to single-chip microcomputer just can control step motor velocity of rotation, stepper motor rotates and moves with certain speed on the axis of electrode by screw mandrel band movable slider, making to be fixed on the distance that the electrode on slide block moves between (also move together the one end that is fixed on the range sensor on electrode) two electrodes changes, thereby reach can real-time inspection and control motor speed.
The arcing that is greater than setting when motor distance between apart from mutual inductor apart from time, walking motor fast rotational; The arcing that is less than setting when motor distance between apart from mutual inductor apart from time, walking motor rotates at a slow speed.
Brief description of the drawings
Fig. 1 is the system principle diagram of the present embodiment.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is remake to description.
Referring to Fig. 1, arc fault intelligent detection device, mainly comprises copper rod A, carbon-point B, high precision range sensor module C and D, motor driver, slide block, walking motor, screw mandrel, base, fixed block and terminals.Two electrodes that copper rod A and carbon-point B are arc generator, electrode A can move with the rotation of motor, and electrode B cannot move.C, D are two modules of range sensor, and module C is fixed in electrode A and can moves along with the rotation of motor, and module D is fixed on above electrode B and cannot moves.The output port of range sensor connects single-chip microcomputer, and arcing distance is that the distance between L. range sensor two module C and D is M, range K.
Principle of work: first write single-chip microcomputer in the arcing distance L of setting according to actual conditions and range distance, start arc generating device, as range sensor two module C, when distance M between D is greater than arcing distance L, by Single-chip Controlling stepper motor fast moving, in the time that the distance M between range sensor is less than or equal to arcing distance L, single-chip microcomputer control step motor is switched to slow rotation.Distance when range sensor in the time that two electrodes oppositely move is greater than the stop motion of range K motor.
