Введение в продукт
Wuhan UHV Power Technology Co.,Ltd., is a professional manufacturer and supplier of high-voltage power testing equipment in China.As an insulating gas, SF6 is non‑toxic, non‑flammable, and offers excellent insulation characteristics. Its insulation strength is significantly higher than that of traditional insulating gases, and it also possesses superior arc‑quenching properties. As a result, SF6 is widely used in SF6 electrical equipment.
However, SF6 gas is expensive, and under the action of arcs, sparks, and corona discharges, it can decompose and produce toxic by‑products. Therefore, SF6 gas recovery is necessary during the application of SF6 electrical equipment. This SF6 gas recovery device manufacturer is specially designed for recovering and recharging SF6 gas during the manufacturing and maintenance of SF6 electrical equipment.
The SF6 gas recovery device is suitable for vacuuming, gas filling, recharging, purification, and recovery of SF6 gas in SF6 electrical equipment.
The SF6 gas recovery device consists of an SF6 gas recovery unit. Its main advantages include the ability to directly store recovered SF6 gas in liquid form in a container, recover residual pressure in GIS to 53 kPa (absolute pressure), compact size for easy mobility and placement, fast vacuuming speed, and the ability to dry and filter the recovered SF6 gas. It can also recharge SF6 gas back into SF6 electrical equipment.

FAQ
Q:What is an SF6 gas recovery unit, and what role does it play in power equipment maintenance?
A:SF6 gas recovery unit is a specialized device used for recovering, purifying, storing, and refilling sulfur hexafluoride (SF6) gas. It enables closed-loop gas management during equipment installation, maintenance, and decommissioning. By reducing SF6 gas emissions and supporting gas recycling, it helps lower operating costs, meet environmental requirements, and ensure that high-voltage electrical equipment can be safely and efficiently returned to service.
Q:What is the purpose of an SF6 gas recovery device?
A:The primary purpose is to safely recover SF6 gas from electrical equipment during maintenance or decommissioning, purify it to remove impurities and decomposition products, and store it for reuse. This prevents the release of SF6 (a potent greenhouse gas) into the atmosphere and reduces the cost of purchasing new gas.
Q:How does the purification system work?
A:The SF6 gas recovery device manufacturer uses a three-stage filtration system with American HASON technology. The built-in drying and heating system allows the desiccant to be regenerated after saturation, eliminating the need for replacement. This ensures continuous, maintenance-free operation.
Q:How does the SF6 gas recovery unit maintain the quality of recovered gas?
A:During the recovery process, the equipment removes impurities and moisture from the gas through filtration and drying systems, while minimizing the risk of ambient air ingress into the system to maintain SF6 gas purity. For gas that has been stored for a long time or comes from complex sources, professional testing methods can be used to confirm whether it meets the requirements for reuse, thereby improving the reliability of equipment operation.
Q:Which power equipment is most suitable for use with an SF6 gas recovery unit?
A: The SF6 gas recovery unit is suitable for GIS (gas-insulated switchgear), SF6 circuit breakers, gas-insulated transformers, ring main units, and other equipment that uses SF6 as an insulating or arc-quenching medium. For equipment with large gas volumes or high maintenance frequency, using a professional recovery unit can improve operational efficiency and reduce environmental impact during maintenance.
