SF6 Gas Recovery and Filling Machine

  • The sf6 recovery and treatment device can recover, purify and replenish SF6-gas with a high degree of safety and reliability during its processing, and provides a variety of functions through automatic drive and control technology.
  • This rugged sf6 gas handling equipment includes multiple components including recovery system, aeration system, vacuum system, purification system and gas storage system. Can store gaseous and liquid SF6.
  • The SF6 tank can withstand pressures up to 5.0mPa, and the SF6 gas can be recovered to a final vacuum of 1 mbar to 5 mbar, which far exceeds the IEC 62271-4 regulations. This type of equipment is equipped with semi-automatic controls and is easy to operate.
  • Through high performance and efficient processes, our SF6 extraction and aeration equipment can dry, filter and liquefy SF6-gas to refill internal storage tanks and external SF6 gas cylinders.

   Description


Description of SF6 Gas Recovery Unit

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.

Gas treatment, purification and filling equipment 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 or test equipment, then fill to storage tank after purifying and compressing. The recovery device is suitable for SF6 electrical appliances and GIS combined electrical apparatus. It consists of a gas recovery system, and an inflating system, a vacuum system, a purification system and a gas storage system.

Advantages of SF6 Gas Recovery Machine

SF6 is commonly used in power applications and is used worldwide in high-voltage circuit breakers, metal-enclosed switch cabinets, linear accelerators, high-voltage transformers, capacitors, and gas-insulated circuits. Due to the special application of gas, there should also be a standardized process for recovering SF6 gas.

Yuneng provides the function of recovering and refilling one air chamber while emptying another air chamber. Our SF6 gas recovery unit uses completely dry compressors and vacuum pumps. The SF6 treatment and recovery device has high safety and reliability in the treatment process, and can recover, purify and supplement SF6 gas.
