GDQT-2 2m³/h High Vacuum SF6 Gas Recovery and Refilling Machine for SF6 Circuit Breaker Maintenance
Product Description
GDQT-2 2m³/h High Vacuum SF6 Gas Recovery and Refilling Machine for SF6 Circuit Breaker Maintenance
SF6 (sulfur hexafluoride) gas, as an efficient insulation arc extinguishing gas, is increasingly being used in the power industry. However, its high-temperature decomposition products are toxic (its harm is thousands of times that of carbon dioxide gas).Due to its nature as a greenhouse gas, it has caused inconvenience for the maintenance and repair of equipment using SF6 gas.
Our company has conducted research on various SF6 gas recovery and treatment devices both domestically and internationally, exploring various processes for gas recovery, filling, drying, ventilation, and replenishment of SF6 circuit breakers. As a result, we have designed this SF6 recovery and filling device.
Main Systems of GDQT-2 2m³/h High Vacuum SF6 Gas Recovery and Refilling Machine:
Which consists of recovery system, vacuum pumping system, adsorption filtration system, electrical control system, etc.
Main Functions of GDQT-2 2m³/h High Vacuum SF6 Gas Recovery and Refilling Machine
5) Filter and adsorb impurities and moisture in SF6 gas, and purify SF6 gas.
Technical Index of GDQT-2 2m³/h High Vacuum SF6 Gas Recovery and Refilling Machine
| 1 | Recovery gas pressure | Initial pressure ≤ 0.88MPa (20°C), final pressure ≤ 1mbar |
| 2 | Vacuuming speed | ≥ 16m3/h |
| 3 | ultimate vacuum | ≤ 10Pa |
| 4 | Compressor system | Adopts oil-free compressor, compressor recovery rate is 2m3/h, output pressure ≥50bar. |
| 5 | Using the metal hard sealing principle, the leakage rate of the joint connection system is less than 1*10-8 mbar l/sec. | |
| 6 | Vacuum degree maintenance of the device: When the vacuum degree reaches 133Pa, after shutting down for 30 minutes and maintaining it for 5 hours, the increase in vacuum degree of the device should not exceed 200Pa (calculation starts when the vacuum degree reaches 133Pa. Keep the vacuum pump running for at least 30 minutes, stop the pump and connect it with the pump Isolate, read the vacuum degree A after watching for 30 minutes. Then wait for more than 5 hours, and read the vacuum degree B. The rising value of the vacuum degree (B-A) ≤200Pa). | |
| 7 | Back-charging speed (20°C): Assume that the equipment volume is 1m3, the initial air pressure is less than 100Pa (<1mBar), the final pressure is 0.5MPa (5Bar), and the filling time does not exceed 30 minutes. | |
| 8 | Quality control of gas purified:

Characteristics of GDQT-2 2m³/h High Vacuum SF6 Gas Recovery and Refilling Machine
(1) The structure of the device is reasonably arranged and beautiful. Each component has good anti-rust and shock-proof capabilities. It is firmly installed and reliable in use.
(2) The frame material is Q235A, and all pipelines and tanks are made of 304.
(3) The connection, disassembly and assembly of each pipeline of the device and the maintenance of each component of the equipment are convenient and easy to operate.
(4) Compression system: Uses a special SF6 closed compressor, no leakage.
(5) Under various conditions of use, the entire gas circuit system is well sealed.The gas system will not introduce impurities such as oil, air, metal dust, etc. into the SF6 gas.
(6) The vacuum system uses a two-stage rotary vane vacuum pump with a solenoid valve to prevent oil return.
(7) The purification system uses a special filter. The filter is electrically heated and equipped with high-efficiency adsorbent. The purification effect is more significant (no need to frequently replace the adsorbent).
(8) The operating system diagram is clear on the 10" touch screen, with intelligent control and one-key control functions.
(9) The equipment has a built-in spiral heater with patented technology to fully vaporize SF6 and inflate it externally.
(10) It has the function of adsorbing and filtering decomposition products and toxic low fluoride.
(11) Has the function of effectively filtering strong acidic gases.
