SF6 Gas Recovery and Filling Machine
- The sf6 recovery and filling machine can recover, purify and replenish SF6-gas with a high degree of safety and reliability during its processing. It also provides a variety of functions through automatic drive and control technology.
- This rugged sf6 gas handling equipment includes multiple components: a 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.
- Our SF6 extraction and aeration equipment can dry, filter, and liquefy SF6-gas to refill internal storage tanks and external SF6 gas cylinders through high-performance and efficient processes.
Description of SF6 Gas Recovery Unit
About SF6 gas
SF6 gas is a good electrical insulator. SF6 gas can provide insulation and ensure the stable operation of the equipment under the normal pressure level that cannot be provided under a vacuum. On the other hand, the SF6 gas can cause a greenhouse effect. If these gases are put into the atmosphere, they will cause great harm to the environment. Therefore, this gas must be handled properly.
About the SF6 gas recovery machine
QTHS-1 series SF6 gas recovery and filling machine is used in the manufacture, use, operation, scientific research, and other departments of SF6 gas-insulated electrical equipment. The SF6 gas was recovered from the tested electrical appliances, and at the same time, it was purified and compressed, and stored in a storage tank. The recovery and purification charging and discharging device are suitable for SF6 electrical appliances and GIS combined electrical appliances.
The tank and purification system of the QTHS-1 series SF6 gas recovery and filling machine are composed of a built-in renewable dry filter, dust filter, ball valve, vacuum gauge, electrical control, control of pressure detection and alarm device, instrument panel, and other auxiliary facilities.
