Automatically Vacuum Helium Leak Detection Equipment for Cast-Aluminium Shell of Switch Gears

The cast-aluminium shell shall be filled with SF6 gas, no leak is permitted. As there might have casting defects, it is necessary to do leak test before SF6 fill. The normal solution is auto vacuum chamber helium leak test system.

Test Concept

• Charge high pressure gas into the product for gross leak test and proof test；

• Evacute the vacuum chamber.

• Vent gas from the product.

• 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.

• Vent vacuum chamber.

Technical specification:

• Cycle time:10min/pcs. (for reference, demanded by customer)

• Leak rate:1.0E-6mbar.l/s. (for reference, demanded by customer)
