Main Property:
All test items of electrical performance are done automatically at one time fast.
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 stator.
Do auto compensation to ambient temperature. It ensures test accuracy.
Single working station/ 2 working stations (selective), high test efficiency and perfect use
Withstand voltage and inter turns voltage adjustment could be operated in manual mode or auto mode.
Systems switch device is made of imported high pressure vacuum steel spring relay, withstand voltage is 10000V, working test 100 million times
Item program could be done according to the test requirement by customers.
Reverse winding inserting test could find out the wrong inserted winding and visually locate it.
Flash-over test focuses on external slot lead. Electric arc appears in high voltage test. It couldn’t verify the motor quality.
It could save, edit and transfer each test standard. |
