LH-WY Series
The LH-WY series devices are suitable for power bureaus, power plants, transmission and transformation substations, high-voltage switch manufacturing plants, electrical research institutes, power engineering companies for the recovery, purification treatment and recharging of sulfur hexafluoride gas. They are particularly suitable for on-site installation and maintenance of 110KV to 550KV GIS switches.
The core advantage of this solution lies in the ability to store the recovered SF6 gas in liquid form and recover the residual pressure in the GIS to 53KPa (absolute pressure). The equipment adopts an integrated design, is compact in size, easy to move, and has the ability to quickly evacuate vacuum. It can dry, filter and recharge the SF6 gas back into the GIS. The built-in filtration adsorption system (unique technology) can efficiently remove impurities, moisture and decomposition products to ensure the quality of the gas. The equipment is equipped with phase sequence protector, temperature protection system and drying heating system, and supports heating regeneration of the desiccant without replacement. All electrical systems use domestic brands, are equipped with high-quality casters to protect the ground, and the entire machine is designed with air cooling, requiring no external water source. In addition, the equipment has a vacuum pumping power-off protection function, eliminating the risk of oil return and ensuring safe and reliable operation.
