Single fracture type classes in other high voltage circuit breakers

With sulfur hexafluoride (SF6) gas as the extinguishing medium or a circuit breaker also be used as insulating medium. Its single fracture type classes in other high voltage circuit breaker. In EHV circuit breakers, SF6 circuit breaker component count, high reliability and breaking capacity, long maintenance cycle, no fire hazard, and  electri cenergy meter  very popular, is developing rapidly. Sulfur hexafluoride gas which is an ideal modern arc  electric meter  medium, by the Frenchman Moisan (Moissan) and Lebow (Lebeau) synthesized in 1900, 1904, began to be used as the extinguishing medium. It is due to its excellent properties with the "negative" of the discharging process, the negative electron and ion forming a plurality of negatively charged binding.
