| Abstract |
In this paper, breakdown characteristics of pure Kr, Ar and N₂ gas with gas pressure range were investigated, and the measured values were compared with those in Ar/N₂ and Kr/N₂ gas mixtures with pressure varying. Also, various characteristics with gas mixtures in practical incandescent lamps were investigated. Summarizing the experimental results, the breakdown voltages of N₂ gas were increased than those of Kr and Ar gas with large molecular weight, and the breakdown voltage increased with gas pressure increasing. The breakdown voltages of Ar/N₂ and Kr/N₂ gas mixtures were decreased with decreasing the mixtures ratio of N₂ gas, and corona inception voltage of Kr/N₂ gas mixtures under non-uniform fields were increased than those of Ar/N₂ gas mixtures. In case of practical incandescent lamps, luminous and lifetime of Kr(70%)/N₂(30%) gas mixtures were increased about 94[㏐] and 380[hr] than those of Ar(70%)/N₂(30%) gas mixtures. and injection pressure of gas mixtures with cooling temperature of 20[℃] in incandescent lamps were increased about 13[%] than those with cooling temperature of 40[℃]. |
