Product application
It is mainly used in SF6 gas filled cabinet / environmental protection cabinet / pole switch / load switch / power casting and other products in the power industry. The size of the inspected products is large and the content is large. Because the wall thickness of most switch cabinets is very thin, the vacuum chamber and workpiece should be vacuumized synchronously.
Main technical parameters reference
Detection accuracy: SF6 annual leakage rate is 0.05% ~ 0.5%;
Detection time: 20min-60min / single chamber;
Inner cavity size of vacuum chamber: customized according to the shape and size of the workpiece to be inspected;
Method of vacuumizing and filling helium: vacuum chamber and workpiece are vacuumized and filled with helium synchronously;
Door opening mode: left and right sliding door, tunnel type, etc;
Leak detection features: three levels of leak detection technology, including large leak detection, medium leak detection and micro leakage detection, can detect the overall leakage rate and find the leakage point;
Helium recovery rate: more than 98%. The helium recovery rate is greatly improved by using low-pressure helium replenishment and seal upgrading;
SF6 is the leading micro water treatment system, which can effectively remove the excessive water
Control mode: PLC control, touch screen operation;
Degree of automation: after manually connecting the workpiece, start the equipment: opening and closing the door, synchronous vacuum pumping, helium filling, detection, recovery and SF6 filling.
Security protection: grating protection, built-in safety switch, electrical interlock, level password control, sound and light alarm.
