Abstract(in English) | If contact members made by steel carrying electric currents wer separated just before separation, the contac resistance and joule heat increase to melt down real contact area between them. Because of the existence of melting bridge betweenh then, electric currents are still flowing in them after geometric separation (boundary contact). After separation, surface damages of them were observed by laser microscope. If supplied voltage was low enough and arc discharge does not occure between them, the damage of anode and cathode were completely unsymmetrical. An hole was digged on the anode, but an pole was constructed on the cathode. If arc discharge occurred between them, the damage of anode and kathode are almost same. Same size holes were digged on them. |
