<p>PURPOSE:To prevent the bad influence due to the contamination, etc., of an insulation substance due to liquefaction detecting the liquefaction starting point of the sealed gas by dissolving the liquefied detected substance into a sensitive substance and detecting the fluidization of the sensitive substance through the reduction of viscosity. CONSTITUTION:When the environmental temperature of the SF6 gas equipment lowers and the temperature of the SF6 gas becomes close to the liquefaction temperature, the dissolution of SF6 in a liquefaction detection body 102 containing fluorocarbon as main constituent proceeds speedily, and the viscosity of the sensitive substance reduces, and a fluidic state is generated. Since load is concentrated at one edge of an accommodation container 101, it turns, having one of a supporting rotary shaft 104 as fulcrum, and the liquefaction detecting contact points 1071 and 1072 are put into each conduction state, and the signals for driving a heater 12 and a blower 11 are transmitted. When the restoration to a prescribed gas pressure is performed, a driving part 1062 for the reset of the accommodation container is excited by the signal supplied from a controller, and one edge of a driving part 1061 for the reset is attracted, and the accommodation container 101 turns, having one of the rotary shaft 104 as fulcrum. At this time, the contact point part is put into electric conduction state, and a detection body 102 set to one side is reset.</p> |
