IV. Technical Parameters
1. AC Hipot: Applied AC high voltage from the silicon steel sheet to iron core, and test the current of testing loop.
|Output voltage setting range/ precision:||AC 200~3000V±(2%×setting value+10V)|
|breakdown current testing range/precision:||0.10~20.00mA±(2%×display value+0.05mA)|
|breakdown current presetting alarm range:||Max:0.10~20.00mA;Min:0.00~20.00mA|
|test time range/resolution:||0.5~999.9s 0.1s/step|
|arc detection:||1~9 (9 is the most sensitive level)|
2. Insulation resistance: apply DC high voltage between winding and iron core and check the insulation resistance of testing loop.
|output voltage setting range/precision:||DC 500V/1000V±(2%×setting value+10V)|
|insulation resistance testing range/precision:||1~500MΩ≤100MΩ:±(3%×display value+0.5MΩ); >100MΩ:±(5%×display value+5MΩ)|
|insulation resistance alarm setting range:||Max:0~500MΩ;Min:1~500MΩ|
|test time range/resolution:||0.5~999.9s 0.1s/step|
3. Surge: apply impulse high voltage to windings, and compare the oscillation graph with the saved graph.
|output voltage setting range/precision:||500~3000V±(3%×display value+8V)|
|Surge graph comparison:||Area, area difference, corona, phase. Three surge graphs will be displayed on the test interface|
4. DC winding resistance: four-wire resistance measuring method. Apply DC current to the windings and test the temperature and winding resistance under current environment. The resistance will be converted to the value under designated temperature(generally 20℃ or 25℃) automatically.
|measuring range and precision:||10.0mΩ~20KΩ±(0.3%×display value+3 words) temperature compensation can be set|
|test time range/resolution:||0.5~999s 0.1s/step|
|temperature probe/measuring range:||DS18b20 -10.0℃~+50.0℃|
5. Inductance: apply electric level signal with preset frequency to the windings and test the inductance of windings.
6. Direction of rotation:the rotation is tested by monitoring the change of magnetic field
|Rotation:||CW, CCW and still|
V. Picture show
VI. Test methods:
1. Set the test sequence and parameters range as to the stator parameters and establish a new model for this type of stator (The model of one stator type needs to be established only for the first time)
2. Put the tested stator on a designated station and clamp it
3. Sliding cover to start the test and the “in-test” indication light is lightening.
4. All the items will be tested. The operator is not allowed to touch the stator during the test.
5. Pass or fail signal will be triggered after completing all items test.
6. Take out the tested stator and continue to test next one from step 2.
VII. Software function introduction
1. All the items can be selected to test or disabled.
2. The motor model can be established up to 1000.
3. The maximum and minimum test value of each type of motor can be entered and saved. The resistance and inductance has the function of setting and displaying the unbalanced degree.
4. Two options are available in case of failing the test result: “continue to test” and “stop the test”. If the winding resistance test failed, the test can be stopped after testing the three windings.
5. The testing data is stored in the data base, and can be exported via USB port.
