| Abstract(in English) | It had been difflcult to measure spectra radiated from switching arc igniting in a miniature relay because of its short duration of less than 1 ms and these weak intensities. In this report, its measurement is carried out using multichannel spectroscopic measurement system with high sensitivity and high speed resolution. A power source and load resistances in the experimental circuit were dc 30V and3Ω, respectively. Contact material mounted on the relay was Pd. The experimental results are as follows. Eight spectra of Pd neutral atoms were identified from spectroscopy. The intensities remarkably increased from ignition, became maximum, and decreased in its termination. As local thermal equilibrium was confirmed with Boltzmann plot, arc temperature was estimated from 7000 to 12,000K. |
