Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
SF6 gas as insulating and arc-quenching medium· Fig. 11-2 Conversion of water vapour content into dewpoint for SF6 gas at atmospheric pressure. Arcing causes the decomposition of very small amounts of SF6 gas. The decomposition products react with water, therefore the gas's moisture content, particularly in the circuit-breaker, is controlled by drying (molecular) filters.
End-of-life factors in high voltage gas insulated ...· If applicable, the impact of non-SF6 gases or gas mixtures on electrical wear of different circuit breaker design (e.g. CO2-breaker, vacuum breaker) has to be discussed between the end user and the equipment manufacturer. If degradation of gases or gas mixtures during switching is to be expected, the impact on lifetime of circuit breaker should ...
