Appearance and anti-corrosion layer inspection |
√ |
Inspect the anti-corrosion layer, casing color, appearance and size of metal parts; |
|
|
Terminal inspection |
√ |
After inserting the plug of the connecting wire into the socket of the terminal, it shall have a self-locking function; |
|
|
Protection device inspection |
√ |
Apply power frequency voltage from low to high to the protective device between each low-voltage terminal of the capacitor and the ground; |
|
|
Air pressure check |
√ |
/ |
|
|
Tightness test |
√ |
Wrap the sealing surface of the capacitor and let it stand for 24, then perform a quantitative test; |
|
|
Mechanical performance inspection |
√ |
Fill the capacitor with nitrogen at 2 times the rated pressure for 72 hours; |
|
|
Withstand voltage test |
√ |
During the test, the capacitor 0 voltage should be continuously boosted to 330kV and kept for 1 minute; |
|
