| Abstract(in English) | Large-scale earthquakes occur successively in world each place, and the serious damage happens in every time. It becomes cause by the fact that a fire from an electric appliance is serious as the one. To minimize this, the relays which saved against earthquake disasters are effective. Therefore, by this paper, it was given vibrations equivalent to earthquake outbreak and investigated a relation between values of electric currents and numbers of vibrations when the relays which saved against earthquake disasters were over life time. Then, It was measured contact resistance and observed the surface of the contact spot from micro meter to nano meter scale with the atomic force microscope (AFM). Based on these results, this paper shows the consideration about reliability improvement and decision of a range stable and usable of the relays which saved against earthquake disasters. |
