| Abstract(in English) | In power relays, in general, the bigger the diameter of a contact becomes, the longer electric durability becomes. From the standpoint of a small-sized and low-cost power relay, it is desirable to quantify the relationship between the diameter and its electric durability to optimize the contact size. We examined the electric durability of a power relay under the conditions of generating deterioration failures by the contact erosion. We found that the bigger the diameter of the contact becomes, the slower the erosion speed becomes, and the rate is not constant and depends on the contact diameter size. For this reason, scattering and re-adhesion of the contact melted by break arcs have been considered. Moreover, in observing the shapes, the sizes, and the locations of re-adhesion traces, these were almost equal, and hence, it is considered that there is a fixed condition among them, and this condition will greatly influence the relationship between the contact diameter and the erosion speed. |
