This equipment is suitable for dry leak detection of SF6 switch cabinets/inflatable cabinets/ring network cabinets. It adopts the method of internal inspection in a helium-filled box to reasonably control the range of pressure difference between the inside and outside of the workpiece without causing abnormal deformation of the product to be inspected. At the same time, it adopts The simultaneous use of pressure sensors and vacuum gauges greatly improves the detection safety factor.
Helium leak detection system for vacuum boxes in the power industry
Vacuum box leak detection system
