| 抄録(英) | Electrical contacts are extensively used for telecommunication and electric power as a device directly making and breaking electrical circuit. In future those are more indispensable presence. The aim of this work is to compare between mass change and surface morphology by using two types of contact with different form. Concerning contact form, one has a curved surface electrode that is generally used, the other is notched in the center of the electrode. This contact form is made in the motif of twin contacts that give high contact reliability. Therefore we expect to attain high contact reliability with this contact form. First, we focus attention on mass change of contacts because the process of contact erosion and material transfer is less well understood. And we investigate the relation between mass change of contacts and surface morphology, arc duration, arc energy, contact resistance. As a result, although the contact resistances of both types keep low and stable, the mass loss of notched contact is larger than generally used contact. Therefore the advantage of notched contact is not confirmed. But we confirm that mass change has close relation to surface morphology, arc duration and arc energy. |
