QAT-2B generator armature integrated tester
This testing machine is applied to test kinds of generator armature, Its LCD shows all technical data which obtained by industrial control computer, which check and verify the quality of testing stator.
Machine specification:
1.AC withstand voltage test.
(1).testing voltage range: AC100～2800V。
(2).voltage adjusting mode(-M: manual adjust.-A: auto adjust)
(a).manual adjust: manual no step adjust
(b).auto adjust: input testing voltage to the software, thus machine do automatic loading to the setting value through the test.
(3).Voltage precision: ±3.0%
(4).Capacity: 500VA
(5).leakage current setting 5 steps(0.5/1/2/5/10mA). precision: ±1.0%
(6).Voltage load way: between coil and iron core.
(7).OK/ Reject verify way: goods of its leakage current value higher than setting value is taken as reject. The software will give acousto-optic alarm accordingly.
2. Insulation resistance test
(1).Testing voltage: DC500V
(2).Testing range: 10～500MΩ
(3).Integrated accuracy: ±5.0%
(4).Voltage load mode: between coil and iron core.
(5).OK/ Reject verify way: manual setting the low limit of insulation resistance, when the
goods of its insulation resistance value lower than setting value is taken as reject. The software will give acousto-optic alarm accordingly.
3. cold resistance test
(1). Testing range:
  (a)0.001-9.999 (resolution ratio 0.100 uΩ).
  (b)1.000-99.99 (resolution ratio 0.010 mΩ)
  (c)100.0～999.9(resolution ratio 0.100 mΩ)
(2). Precision: ±0.5% auto temperature compensate, could be calculated to resistance
value at 20℃
(3).testing way: between winding and winding.
(4). OK/ Reject verify way: Program reads the testing value of winding and verify ok/reject by comparison of upper and low reference value. The software will give acousto-optic alarm accordingly when it's reject.
4. Between turns insulation test
(1). Testing voltage range: 100V～2800V
(2). Voltage Precision: ±3%
(3). Voltage adjusting mode(-M: manual adjust,-A: auto adjust).
(a). manual adjust: manual adjust with no section.
(b). auto adjust: input testing voltage to the software, load to the setting value automatically when testing.
(4). Pulse rising time: 1.2μs
(5). Verify way:  Δs/s  Δf/f
(6). Voltage load way: testing each winding respectively.
(7). OK/Reject verify way: Program reads the standard value of wave between turns, compare the testing wave to standard wave. The software gives acousto-optic alarm if beyond setting value.
Main feature:
1.All test items of electrical performance are done automatically at one time fast.
2.Each test items could be on or off randomly. Approval standard also could be set up randomly. The machine will give acousto-optic alarm for reject armature
3.Do auto compensation to ambient temperature. It ensures test accuracy.
4.Single station/double station can be chosen, with high utility and testing efficiency
5.Withstand Voltage and between turns voltage can adjust by manual or automatic.
6.System switch part use imported high voltage vacuum steel spring tube relay, withstand voltage 10000V,work test 100000000 times
7.Customer can do item programming automatically as per testing requirement.
8.It can save, edit, call kinds model stator and check data specification automatically.
