知られている。Gases with better insulation performance than SF6 include propionitrile pentafluoride (FsON), which has a dielectric strength 1.8 times that of SF6, and bromochlorosif/, which has a dielectric strength 1.4 times that of SF+.
A group of 70-neck carbons such as L/olomethane (,0BrOσ2) and octafluorocyclobutane (O04Fs) are known.
しかし、これらのガスは単独で絶縁ガスとして用いると

ル％の範囲で好適な結果か借られた。The invention will be explained below. The inventors attempted to separate and quantify carbon powder, which is a 41' FfL particle, from among the powder generated during arc generation, and found that 0.5 mol% of 02F5ON mixed dead metal mixed in SF6 gas was used. ,2
0 mol%, 50 mol%, and 100 mol%, and tested the relationship between the amount of carbon powder produced per unit arc generation time during arc generation and the arc's light (first wave height 1 plane). The results shown in the figure were obtained 7ζ0 According to this, suitable results were obtained for the amount of the fluorocarbon compound mixed in the range of 0.5 to 50 mol % based on the total amount mixed with SF6.

・陽れた分だけ座直の小形化を図ることができる。According to this, it was found that the amount of carbon powder produced by the mixed gas was less than the amount of carbon powder produced by the pure gas. In addition, in the above-mentioned fluorocarbon compound, if the composition ratio of the fluoro(arsenic) compound in the mixed gas is less than 50 mo/lz%, the amount produced is smaller than expected based on the composition ratio.
4. As shown in Table 1, the dielectric strength of the mixture of SFs and fluorocarbon compound is 11 more than that of SF6 gas alone. Therefore, it is possible to reduce the size of the seat by increasing the insulation properties.
