  • Relevance of SF6 in Switchgear and its Contribution to

    Sulfur hexafluoride (SF6) is one of the most stable gaseous chemical compounds due to its inertness (Its inertia is comparable with nitrogen (N2) gas) and incombustible nature. It has been more than 6 decades since SF6 is being used in electrical equipment. In fact, Switchgear amounts to 90% of the electronic equipment that uses SF6.

  • CDC - Mining - Electrical Equipment Explosion Protection

    GeneralRecent Niosh-Sponsored Efforts in The Area of Explosion Protection ResearchConsiderations of Other TechniquesFuture Direction of Explosion Protection Research“Explosion protection” refers to techniques used to minimize the potential for electrical and electronic equipment to create an ignition while operating in a hazardous location (HAZLOC). A HAZLOC refers to atmospheres containing flammable gases or vapors and/or combustible dusts. In particular, U.S. coal mines and other gassy mines are required to use equipment in certain areas of the mine that has been approved by the Mine Safety and Health Administration (MSHA) for use in a methane and coal dust environment to limit the risk of the equipment creating an ignition-capable spark or a thermal energy ignition. There are three basic means of providing explosion protection for equipment; these are, precluding the gas (explosive mixture) from reaching the circuitry, limiting the energy of the circuitry so that ignition is not possible, or containing the explosion to the area immediately surrounding the circuitry so that it cannot propagate into the surrounding environment. The NIOSH-spons...
