  • Development Sf6 Alternative Gases in Switchgears - Switchgear

    Nov 23, 2019 · Sf6 gas is widely used in electric power transmission and distribution systems, as for example in gas insulated switchgear (GIS), circuit breakers (CB) and load break switches. It combines unique electrical insulation and arc interruption capability. However, it is also a very strong greenhouse gas with a global warming potential (GWP) of about 23500 over a time horizon of 100 years and its use and release are regulated with further restriction being discussed.

  • 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.
