| 講演名 | 2014-11-29 16:00 Comparisons on Arc Behavior and Contact Performance between Cu and Cu-Mo Alloys in a Bridge-type Contact System ○Mo Chen・Xue Zhou・Guofu Zhai（Harbin Inst. of Tech.）  EMD2014-76 |

| 抄録 | （和） | Cu-Mo alloy carries forward the high conductivity and high-thermal conductivity from Cu and high hardness from Mo. It gets widely applied in electrical contact fields. In this paper, the arc characteristic and erosion characteristic of Cu-Mo contacts are studied with a bridge-type contact high speed break mechanism in DC270V/200A load condition. And in every experiment group, 1000 times break operations are carried out. During every break operation, a high speed AD card is used to collect voltage and current signal of contacts, a high speed camera is applied to record arcing process, and the temperature of contacts and arc are acquired by thermocouple and spectrometer separately. The arc characteristic is studied through the above methods. The mass and contact resistance of contacts is measured before and after every group experiment. Besides, the photograph of contact surface is taken by SEM to help analyze the erosion characteristic. The comparison between Cu-Mo contacts and Cu contacts indicates that although Cu contacts have a better electrical conductivity and thermal conductivity, Cu-Mo contacts can decrease the temperature of arc to prevent thermal breakdown, they are also harder to ablate and have a longer life. |
