Abstract
The utility model provides a three -phase alternating current motor phase sequence detection device, three -phase alternating current motor phase sequence detection device set up interconnecting link at the built -in control circuit board of box body and are connected with the sensor on the motor drive pullery, box body one side is used for the external circuit that links to each other that detects to divide two to connect open -phase detecting ware and motor respectively, the open -phase detecting ware is established the bull circuit in addition and is connected with control circuit board. The detection device who from this constitutes during the use, in the back that links to each other with the motor, can carry out the short -term test to the phase sequence that turns to of motor to but this to avoid electrical phase sequence make a fault and damage the motor and lead to other to connect the loss.
Description
Technical field
This utility model is related to a kind of motor detection apparatus, specifically a kind of three phase alternating current motor Phase sequence detection dress
Put.
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 to reversely rotate, connected miscellaneous equipment thus will be led to make a fault, also can cause not when serious
Predictable accident occurs, and directly harm produces and personal safety.Common three-phase phase-sequence detection is electronic type detection, by 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, to judge whether phase sequence is correct, but general
Logical three-phase phase-sequence detection is only applicable to the moderately good three-phase electricity situation of waveform comparison, leads to three-phase electricity not when waveform is distorted
When stablizing, to power supply disturbance, easily the detection at impact three-phase potential angle is inaccurate, leads for such as mobile generator, or inductive load
Cause Phase sequence detection mistake.
Content of the invention
The purpose of this utility model is to solve above-mentioned problem, provides a kind of small volume, compact conformation, user
Just motor phase sequence detection means, can detect to motor direction of rotation, to determine whether phase sequence is correct.
This utility model includes box body, and the technical scheme being adopted is：Three phase alternating current motor detection device for phase sequence is in box
The control board setting connection line put in vivo is connected with the sensor on motor driving belt disk；Box body side is used for externally
The circuit that detection is connected bifurcates and connects phase loss detector and motor respectively；Phase loss detector separately sets bull circuit and control circuit
Plate connects.
This utility model has following advantageous effect：The detection means thus constituting, after line related connects, phase shortage is examined
Survey device and first detect whether phase shortage, if phase shortage, motor does not rotate, if not phase shortage, motor rotates, and sensor can fast and accurately detect
Motor direction of rotation, by the detection to direction of rotation, can quickly detect to involved phase sequence, it is to avoid cause unexpected damage
Lose, when solving present three phase alternating current motor connection power supply, phase sequence easily occurs and slips up and damnous problem, simple section
Learn, easy to use, detection accurately and reliably.
Brief description
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is this utility model structural representation.
Specific embodiment
Shown in Fig. 1：Three phase alternating current motor detection device for phase sequence arranges connection line 6 in the built-in control board of box body 12
It is connected with the sensor 3 on motor 5 driving belt disk；The circuit 8 that box body 1 side is connected for external detection bifurcates and connects respectively
Connect phase loss detector 4 and motor 5；Phase loss detector 4 is separately set bull circuit 7 and is connected with control board 2.
Control board 2 involved by this utility model is the control element of whole detection device for phase sequence, is for receiving
Phase loss detector 4 and the signal of sensor 3, analytical calculation and whether correctly judge phase sequence, intraware by resistance, electric capacity, two
The integrated circuit that the elements such as pole pipe, audion, phase inverter, manostat and relay combine；Involved phase loss detector 4
It is for detecting whether phase shortage, the integrated electricity being mainly made up of resistance, electric capacity, diode, audion, phase inverter and manostat
Road, involved motor 5 is used for providing the three-phase miniature motor in detection direction, power≤0.5W for sensor 3.Control board
2 and phase loss detector 4 can directly pass through market construction.
