Used for maintenance of high voltage switch cabinets below 220kV
SF6 compact loading and unloading device, specially designed for little and medium gas insulated switchgear. the utmost tank capacity is 70L. Equipment with filtering and drying functions, providing automatic manual selection.
The sulphur hexafluoride gas is recovered and stored for liquefaction, and therefore the stored sulphur hexafluoride gas are going to be re-injected into the switch cabinet to filter and dry the recovered sulphur hexafluoride gas, thereby vacuuming the equipment itself
Digital vacuum gage or vacuum sensor is employed to accurately display the vacuum degree. With negative pressure recovery, improve recovery efficiency. Reserve the staple gas stroke bottle interface. The outlet of the air pump is provided with an environmentally friendly discharge device. The air pump features a spare oil valve to stop oil backflow. Optional 70L tank is provided with a separate tank gas heating plant to enhance filling efficiency.
