The insulation resistance tester under UHV power can help many power workers conduct various power tests more conveniently.

1. It is not required to be in a water state when measuring insulation. When there is no water, the stator is qualified when measured with a vibration exciter of 2M or more; The coil water is not dry, measure it using the vibrating screen wiring method. After passing through water, the intelligent insulation resistance tester is a cold intelligent insulation resistance tester, and the motor insulation tester is 6M. The above are qualified.

2. Due to the grounding of the external cold water pipeline, the shielding is the leakage current generated in the water after the vibration table is pressurized.

3. The water collection ring and the external fixed cold water pipeline are insulated with connecting flanges.

4. The operating conditions measured by the dual water dedicated vibrator are: the stator enters the water through the coil; The insulation resistance of the water collection pipe and the water intake pipe should be greater than 30K Ω; the water-cooled motor should undergo a water test, and the conductivity should not exceed 2.0 × 102 μ S/m2 when it is 20 ℃. When measured with a regular vibration meter, the stator coil should be blown clean and measured

5. If using a water-cooled generator to measure the insulation of the stator, a dedicated water shaker should be used and the water connection of the intelligent star battery tester should be shielded.
