Multiple Stress Testing
1. Test sample: Two test insulators of the same design with a creepage distance between 500mm and 800mm,
2. Procedure: Conduct the test in a sealed, damp, and corrosion-resistant test chamber, with a volume not exceeding 20M3. Figure B1 is a schematic diagram of this test chamber
3. Separate observation holes for wipers and movable ultraviolet filters to observe the equipment in the experiment.
4. Test conditions: As shown in Figure B2, various stress cycles are applied to the insulator, which are repeated for about 5000 hours. During the equipment cycle test, the test sample should be subjected to temperature changes and condensation.
5. As shown in Figure B3, the test is installed vertically in the middle of the test, with a minimum distance of 400mm between the adjacent umbrella edges of the test specimen and the top, as well as between the test specimen and the wall and ground Before the experiment begins, the test sample should be cleaned with deionized water,
7. Up to three pairs of samples with similar creepage distances can be tested simultaneously
8. Voltage: The value obtained by dividing the creepage distance of the test sample (in mm) by 34.6 (equivalent to a creepage distance of 20mm/KV, calculated based on the phase to phase voltage).
