Abstract: The DC interrupting device includes a main current conduction unit including a main interrupting switch, which is a mechanical switch, a reverse current power supply unit connected to an input terminal of the main current conduction unit and configured to generate a predetermined reverse current, and a reverse current conduction unit configured to supply the reverse current to an output terminal of the main current conduction unit. The reverse current power supply unit includes a first reverse current dedicated capacitor charged by a voltage applied to an input terminal of the main current conduction unit, a polarity reversing inductor configured to reverse a polarity of the first reverse current dedicated capacitor, and a reverse current power supply unit switch configured to perform circuit connection such that the polarity reversing inductor reverses the polarity of the first reverse current dedicated capacitor.

Abstract: The present invention relates to an insulating gas used for electrical insulation or arc extinguishing of an electrical device, and an electrical device for insulating electricity using the same. The insulating gas of the present invention, which may replace SF6 gas, consists of a mixed gas of trifluoromethyl trifluorovinyl ether (CF3OCFCF2) and a carrier gas. The insulating gas of the present invention has the characteristics of a low boiling point, high dielectric strength, low toxicity, and a low global warming potential (GWP=1 or less), and thus may replace SF6, and the low global warming potential with no loss of high insulating capacity and arc extinguishing capability may reduce greenhouse gases.
