  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, Sulfr hexafluoride circuit breakers are wid

  • CGA S-7—2005 METHOD FOR SELECTING PRESSURE RELIEF DEVICES FOR

    1 Introduction2 Scope5 Description of Method and Procedures6 ReferencesThis publication presents a method for selecting pressure relief devices (PRDs) for compressed gas mixtures packaged in cylinders having water capacities of 1000 lb (454 kg) (see U.S. Department of Transportation [DOT] Title 49 of the U.S. Code of Federal Regulations [49 CFR] Part 173.301 [f]). This standard also applies to DOT 3AX, 3AAX, and 3T cylinders having water capacities over 1000 lb (454 kg) that comply with the specifications, charging, and maintenance regulations of DOT or the corresponding specifications and regulations of Transport Canada (TC) [1, 2].1 The task is more involved than the method for determining the appropriate valve outlet connections for gas mixtures. For the latter, as described in CGA V-7, Standard Method of Determining Cylinder Valve Outlet Connections for Industrial Gas Mixtures, mixture component rating numbers are assigned to the various compressed gases based on the physical properties of the gases, i.e., flammability, toxicity, state of the gas,...
