Characteristics of Break Arcs Generated between Cu, Al and Fe Electrical Contacts in a 100-280VDC/10A Resistive Circuit
Aoi Handa, Junya sekikawa (Shizuoka Univ.) EMD2023-38
Abstract (in Japanese) (See Japanese page) 
(in English) Break arcs were generated using Cu, Al, and Fe as electrical contacts in the resistive load circuit with supply voltage of 140-280 V and the current of 10A. Experiments were conducted using the same material for the cathode and the anode, as well as using different materials for the cathode and anode. The break arcs were observed by high-speed cameras. Following results were obtained. Using same materials for cathode and anode, the arc voltage increased with fluctuation only for using Al contacts. When the Fe contacts were used, the emission brightness of the break arcs was higher than when using the other Cu, and Al contact pairs. When different materials of Cu and Al were used for cathode and anode, when Al is used as the anode, the arc voltage increased with fluctuation. The brightness of the break arc was higher when Al was used as the anode than when Cu was used as the anode. The arc duration was slightly longer for cases of Al and Fe contact pairs than that for Cu contact pair. The anode material dominated the arc duration. It was shown that the characteristics of the break arcs were mainly influenced by the contact material used for the anode.
