Gas discharge is the various forms of current circulated in the gas atmosphere.Under normal state,gas that is isolated from a variety of external ionization isnot conductive. But,in fact,due to ultraviolet radiation,cosmic rays and radiationfrom the inter...[繼續(xù)閱讀]

    Since the observation of thunder and lightning,humans have gradually explored themysteries of gas discharge,and the study of gas discharge also has a history of morethan 100 years. At present,there are still a lot of people around the worldresearching gas...[繼續(xù)閱讀]

    Depending on the gas pressure,electrical power,electrode shape and other factors,after gas breakdown the discharge will show a variety of different forms; thedischarge phenomenon can be observed through the discharge tube.When the gas pressure is low and ...[繼續(xù)閱讀]

    We do not want gas breakdown in transmission lines and electrical equipment,butin many other areas,the gas discharge has been widely applied,such as energy,metalsprocessing,xerography,environmental protection,etc. They all gradually show greateconomic ben...[繼續(xù)閱讀]

    In order to ensure the safety of electrical equipment and the whole power system,electrical equipment must have reliable insulation,so that it has a certain degree ofelectrical strength. The majority of electrical equipment uses a gas medium as aninsulati...[繼續(xù)閱讀]

    SF6 is a colorless,odorless,non-flammable,non-toxic,extremely stable gas whichis an excellent electrical insulator. SF6 has an octahedral geometry,consisting of sixfluorine atoms attached to a central sulfur atom. SF6 gas has high dielectric strength,exce...[繼續(xù)閱讀]
