Helium Leak Detection With SF6 Filling System for High Voltage Switch Gears
The vacuum helium leak test system is suitable for air tightness detection and helium filling of SF6 High Voltage Switch Gears. It mainly refers to filling helium into workpieces, processing helium recovery filling SF6 gas into workpiece within the specified time, then control the filling pressure to guarantee the qualified rate of the product.
The automatic helium leak detection system has 1 vacuum chamber. The operator puts the workpiece into the fixture in the vacuum chamber, connects the workpiece interface with the quick connector, and turn on the button to close the chamber. After the door closes, the system can automatically complete the whole process like vacuum, gross leakage, helium filling, Fine leak detection, helium recovery, SF6 filling and so on.
