| Abstract(in English) | In this study, the earthquake disaster prevention relay was used, seismic acceleration (972gal) at the Hanshin-Awaji Earthquake level was dealt, and the deterioration process on the surface of the contacts was measured. The surface roughness as the shake frequency rise to increase in the surface of the contacts. It has been understood that the increase of the surface roughness has a big damage on the plating layer on the surface of contact by it, and shortens the contact longevity. The present study examined the mechanism to which the loose contact (sensor defect) occurred because of the oscillatory phenomenon of contacts for a long time. |
