RTQC-60 Vacuum Pumping Device Mainly Used for Porcelain Column SF6 Circuit Breakers



The vacuum pumping device is mainly used for vacuuming and vacuum degree measurement during installation, operation, and maintenance of porcelain column SF6 circuit breakers, transformers, and other SF6 electrical equipment. It is a compact SF6 gas charging and pumping device, with the entire charging and vacuum pumping device mounted on a very sturdy metal frame that can move freely even on gravel roads. The device complies with the DL/T662-1999 "SF6 Gas Charging and Recovery Device" standard and consists of a vacuum pump, pointer vacuum gauge, regulating valve, gas pipeline, and necessary valves and instrument control components for maintaining SF6 circuit breakers. It has the following main functions: 1. Vacuuming and vacuum measurement for SF6 electrical equipment; 2. Charging SF6 electrical equipment.
