QTHS SF6 Gas Refilling and Treatment Device

  1. Yuneng is a manufacturer of sf6 gas refilling device. This sf6 gas filling equipment uses advanced refiling technology for a wide range of gas treatment, gas purification and gas filling.
  2. SF6 gas is a good electrical insulator. SF6 gas can not only provide insulation, but also ensure the stable operation of the equipment under the normal pressure level that cannot be provided under vacuum. On the other hand, the SF6 gas can cause a greenhouse effect. If these gases are put into the atmosphere, it will cause great harm to the environment. Therefore, this gas must be handled properly.
  3. This series of SF6 gas processing equipment uses high-pressure liquefaction and air-cooling technology to store gas in the form of liquefied gas, which is safe and not easy to leak. The recovered SF6 gas dust content is less than 1 micron. The power of the equipment can be adjusted according to your needs.

Application of SF6 Gas Refilling Device

SF6 Gas Handling and Refilling Machine widely used in SF6 gas insulated electrical equipment factory, use, operation, scientific research departments and so on, to create a vacuum for a variety of electrical equipment, and fill electric equipment with SF6 gas, and recover SF6 gas from the use of test equipment, then fill to storage tank after purifying and compressing. The recovery device is suitable for SF6 electrical appliance and GIS combined electrical apparatus. The gas recovery unit of  SF6 is based on the standard of DL/T662-2009 "SF6 gas filling and recovery device", which consists of a recovery system, and inflating system, a vacuum system, a purification system and gas storage system.


Features of SF6 Gas Refilling Device

  1. Vacuum and check vacuum pressure for retrieving device itself including its storing vessel and pipes;
  2. Vacuum and check vacuum pressure for the insulation equipment;
  3. Retrieve and store SF6 gas and check the remaining vacuum pressure of the insulation equipment;
  4. Get rid of water content and other particulates in the SF6gas with filtration and purification process;
  5. Refill up the SF6 gas into the insulating equipment to specified operating pressure.

Advantages of SF6 Gas Refilling Device

  1. Advanced design, full function and compact structure with the simple operation;
  2. Compressed systems: it takes a closed compressor to ensure no leakage;
  3. Vacuum systems: it takes the rotary vane vacuum pump to prevent oil returning;
  4. Purification systems: Equipped with Ingersoll Rand filters which take electric heating and high efficient adsorbents. Without frequent replacement of the adsorbents, so the purification result is better;
  5. Electric systems: Equipped with automatically confirmation three-phase power devices, failure protection;
  6. Control systems: the valves take the latest technology;
  7. Storage system: Provide the storage tank according to users' requirements;
  8. This equipment is a mobile type.
