Auto Helium Leak Testing Vacuum Chamber and SF6 Charging Rig for SF6 Thin Shell Switchgears

Equipment Overview
The switch shell filled with SF6 gas, no leakage, but may exist welding defects, gas filling to tightness test. Shell switches usually use helium leak detection system of automatic vacuum box.
Switch thin shell, unable to bear large pressure difference, usually helium, dry degree detection and SF6 filling technology for are integrated within a system, the system has precision sensor to control thin shell pressure difference between the inside and outside.
Detection principle
Vacuum chamber vacuum;
Detection of pressure drop in the workpiece to determine the large leakage;
Workpiece vacuum;
Workpiece filled with helium;
Vacuum leak detection of helium leakage signal to judge the small box;
Helium recovery
Workpiece filling SF6
Vacuum tank filling atmosphere
Technical parameter:
Production beat: 1 hours / piece
Detection leakage rate: 1 x 10-6mbar.l/s
Detection pressure: 0.5bar
