The present invention provides a kind of three phase alternating current motor detection device for phase sequence, and three phase alternating current motor detection device for phase sequence arranges connection line at the control circuit plate that box body is built-in and is connected with the sensor on motor-driven belt pulley；Box body side sets connection phase loss detector and motor respectively for the circuit that externally detection is connected；Phase loss detector separately sets bull circuit and is connected with lack detection circuit.The detection device thus constituted, during use, after being connected with motor, can turn to phase sequence to be used for quickly detecting in motor, motor phase sequence can be avoided to make a fault with this and damages motor and cause other connection loss.
Description
Technical field
The present invention relates to a kind of motor detection apparatus, a kind of three phase alternating current motor detection device for phase sequence.
Background technology
In manufacturing enterprise, involved motor is more, but when the three-phase alternating-current supply of motor connects, loses if there is connecting
By mistake, will result in motor and reversely rotate, connected miscellaneous equipment thus will be caused to make a fault, also can cause not time serious
Predictable accident occurs, and directly harm produces and personal safety.Common three-phase phase-sequence detection is electronic type detection, passes through waveform
The number of degrees at the phase angle of detection three-phase electricity, the phase angle number of degrees between detection three-phase electricity are poor, judge that phase sequence is the most correct, but general
Logical three-phase phase-sequence detection is only applicable to the three-phase electricity situation that waveform comparison is moderately good, causes three-phase electricity not when waveform is distorted
When stablizing, such as mobile generator, or inductive load is to power supply disturbance, and the detection easily affecting three-phase potential angle is inaccurate, leads
Cause Phase sequence detection mistake.
Summary of the invention
The problem that it is an object of the invention to solve above-mentioned existence, it is provided that a kind of volume is little, compact conformation, easy to use
Motor phase sequence detection device, can detect motor direction of rotation, to determine that phase sequence is the most correct.
The present invention includes box body, and the technical scheme used is: three phase alternating current motor detection device for phase sequence is in box body
The control circuit plate put arranges connection line and is connected with the sensor on motor-driven belt pulley；Box body side is for externally detection
The circuit being connected sets connection phase loss detector and motor respectively；Phase loss detector separately sets bull circuit and lack detection circuit
Connect.
The present invention has a following advantageous effect: the detection device thus constituted, after line related connects, and phase loss detector
First detecting whether phase shortage, if phase shortage, motor does not rotates, if not phase shortage, electric machine rotation, sensor can detect motor fast and accurately
Direction of rotation, by the detection to direction of rotation, can quickly detect involved phase sequence, it is to avoid cause accidental loss,
Solve present three phase alternating current motor when connecting power supply, phase sequence error easily occurs and damnous problem, simple science, make
With convenience, detection accurately and reliably.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Shown in Fig. 1: three phase alternating current motor detection device for phase sequence arranges connection line 6 at the control circuit plate 2 that box body 1 is built-in
It is connected with the sensor 3 on motor 5 driving belt dish；Box body 1 side sets circuit 8 respectively for the circuit 8 that externally detection is connected
Connect phase loss detector 4 and motor 5；Phase loss detector 4 separately sets bull circuit 7 and is connected with control circuit plate 2.
Control circuit plate 2 involved in the present invention is the control element of whole detection device for phase sequence, is for receiving phase shortage
Detector 4 and the signal of sensor 3, analytical calculation and whether the most correctly judge phase sequence, intraware by resistance, electric capacity, diode,
The integrated circuit that the elements such as audion, phase inverter, manostat and relay combine；Involved phase loss detector 4 is to use
In detecting whether phase shortage, the integrated circuit being mainly made up of resistance, electric capacity, diode, audion, phase inverter and manostat,
Involved motor 5 for providing the three-phase miniature motor in detection direction, power≤0.5W for sensor 3.Control circuit plate 2 He
Phase loss detector 4 can directly pass through market construction.
