FTHS series SF6 gas recovery device is suitable for vacuuming, filling, refilling, purifying and recovering sulfur hexafluoride gas in SF6 electrical equipment. The system includes vacuuming and refilling system, purification system, compression system and condensation system, and can be used in power supply companies, power transmission and transformation engineering companies, power plants, ultra-high voltage transmission and transformation stations, SF6 electrical switch manufacturers and other departments as auxiliary equipment used in the installation, adjustment and maintenance of SF6 electrical products such as GCBP, GCBT and GIS.
Main Functions
1). Vacuuming and Measuring the vacuum degree of the device and electrical equipment;
2). Recycle the gas in the electrical equipment;
3). Dry and purify SF6 gas recovered and refilled;
4). Inflate SF6 electric appliance;
5). Compressed storage and bottle filling of SF6 gas in electrical appliances.
1) Advanced design, full function and compact structure with simple operation.
2) Compressed systems: it takes closed compressor to ensure no leakage.
3) Vacuum systems: it takes rotary vane vacuum pump to prevent oil returning
4) Purification systems: Equipped with special filters which takes electric heating and high efficient
adsorbents. Without frequent replacement of the adsorbents, so the purification result is better.
5) Electric systems: Equipped with reliable three phase power devices and automatic protection of phase break in the electrical system of the device, failure protection.
6) Control systems: adopts SF6 special valve with the latest technology.
7) Storage system: Provide the storage tank according to user's requirements.
