SF6-Air Liquefaction System for 121kv

Jul 17, 2014Gas System. Since the gas pressure is very high, a lot of care is to be taken to prevent gas leakage at joints by providing perfect scaling. The low and high-pressure systems are fitted with low-pressure alarms and set of lockout switches which give a warning the moment the gas pressure drops below a certain value

    liquefaction systems are typically slower than refrigerated systems. Refrigeration-Assisted Liquefaction Rather than relying on compressors to generate enough pressure to liquefy, refrigerated systems extract the heat of compression from the SF 6, causing it to condensate. At 40&F, the main compressor need only generate
