LH-WY Series SF6 Gas Recovery Equipment
The core advantage of this scheme is the ability to store the recovered SF6 gas in liquid form and recover the residual pressure inside the GIS to 53KPa (absolute pressure). The equipment adopts an integrated design, with a compact size, easy mobility, and fast vacuum pumping capability. It can dry, filter, and recharge SF6 gas to GIS. The built-in filtration and adsorption system (unique technology) can efficiently remove impurities, moisture, and decomposition products, ensuring gas quality. LH-WY Series SF6 Gas Recovery Equipment is equipped with a phase sequence protector, temperature protection system, and drying heating system, supporting desiccant heating regeneration without the need for replacement. All electrical systems adopt domestic brands, equipped with high-quality casters to protect the ground, and the whole machine is designed with air cooling without the need for an external water source.

Advantages
The core advantage of this solution lies in its ability to store recovered SF6 gas in liquid form and recover the residual pressure inside the GIS to 53KPa (absolute pressure).
The equipment adopts an integrated design, making it compact in size, easy to move, and capable of rapid vacuum pumping.
It can dry and filter SF6 gas and refill it into the GIS. The built-in filtration and adsorption system (proprietary technology) efficiently removes impurities, moisture, and decomposition products, ensuring gas quality.
The equipment is equipped with a phase sequence protector, a temperature protection system, and a drying heating system, supporting desiccant regeneration through heating without the need for replacement.
All electrical systems use domestic brands. It is equipped with high-quality casters to protect the floor. The air-cooled design of the whole machine eliminates the need for an external water source.
In addition, the equipment features a power-off protection function during vacuum pumping to eliminate the risk of oil backflow, ensuring safe and reliable operation.
Application
The LH-WY Series SF6 Gas Recovery Equipment is suitable for the recovery, purification, and refilling of sulfur hexafluoride gas in power supply bureaus, power plants, transmission substations, high-voltage switch manufacturers, electrical research institutes, and power engineering companies. It is particularly suitable for on-site installation and maintenance of 110KV to 550KV GIS switches.
FAQ
Q: What is the minimum residual pressure the device can achieve inside a GIS unit during recovery?
A: The device is designed with high-efficiency recovery capabilities. It can recover SF6 gas until the residual pressure inside the GIS reaches 53 KPa (absolute pressure), ensuring minimal gas wastage. Furthermore, it stores the recovered gas in liquid form to maximize storage capacity.
Q: Does the equipment require an external water source for cooling during operation?
A: No, it does not. The entire machine adopts an air-cooled design, which eliminates the need for an external water source. This makes the device highly adaptable to various on-site environments where water might not be readily available.
Q: How does the device handle the regeneration of the desiccant (drying agent)?
A: The equipment features a built-in drying heating system that supports desiccant heating regeneration. This means the desiccant can be regenerated in situ by heating, so there is no need to frequently replace the desiccant material, reducing maintenance costs and effort.
Q: What safety mechanisms are in place to protect the vacuum pump during unexpected power outages?
A: The device is equipped with a specific vacuum power-off protection function. In the event of a sudden power failure while the vacuum pump is running, this system activates to prevent oil from flowing back into the system (oil return risk), ensuring the safety and reliability of the equipment.
Q: Is the device suitable for on-site maintenance, or is it stationary?
A: It is specifically designed for mobility. The unit features a compact, integrated design and is equipped with high-quality casters (wheels) that protect the floor. This allows for easy movement and makes it particularly suitable for on-site installation and maintenance of 110KV to 550KV GIS switches.
Q: What measures are taken to ensure the purity of the recovered SF6 gas?
A: LH-WY Series SF6 Gas Recovery Equipment utilizes a proprietary built-in filtration and adsorption system. This unique technology efficiently removes impurities, moisture, and decomposition products from the gas during the recovery and purification process, ensuring that the refilled SF6 gas meets high-quality standards.
