Auto Helium Leak Detection Equipment For High Voltage Switch Gears With SF6 Filling System
Product Introduction:
According to the basic leak detection principle of helium, the system uses helium as the tracer gas, helium filled into the helium chamber, and then detect the leak within the helium signal through the helium leak detector, can quickly and accurately determine the leakage accuracy of the workpiece

Application
The 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.
Operation process
The 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.
