Automatic Vacuum Chamber Helium Leak Test and SF6 Charging Rig for SF6 Thin Shell Switch Gears
The stainessless thin shell shall be filled with SF6 gas, no leak is permitted. As there might have welding defects, it is necessary to do leak test before SF6 fill. The normal solution is auto helium leak test system.
As the stainessless thin shell can only bear limited pressure difference, the helium leak test, dryness test and SF6 fill process are completed inside a integrated system, pressure difference of inside & outside of thin shell is controlled by a precise pressure.
Evacute the vacuum chamber.
Check the pressure drop inside the product for gross leak test.
Evacuate the product and charge helium into the product.
Test the helium signal from the vacuum chamber by the leak detector for fine leak judge.
Recover helium from the product.
Charge SF6 into the product.
Vent vacuum chamber.
