| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Heat problem, which is generated in the bridge and arcing at breaking contact, is the important origin of the malfunction of the electrical contacts such as transfer and/or wear of the electrodes. In this paper, the effect of holder structure on the heat and temperature rise of the electrode is discussed on the slowly moving contacts, 100~$\mu$m/s, to compare the calculated and experimental results. The bridge generation was related to the heat at the breaking of the electrical contact. To clarify the influence of the heat on the bridge generation and electrode surface temperature rise, 3 types of the holder structure (cylinder type and plate type) with different heat radiation are compared. In the calculated results, there was a difference about twice by the calculation at the electrode surface temperature. The difference of the heat radiation causes the difference of the bridge voltage vibration in the experimental results. When heat radiation was large, the vibration became a faster vibration. It was suggested that the heat radiation influences of heat radiation on the diameter and the length of the bridge. | |
