| 講演名 | 2013-11-17 10:25 Experimental study on root profile of molten bridge under different current at low opening speed Xinyun Zhang・Xinglei Cui・○Xue Zhou・Guofu Zhai（Harbin Inst. of Tech.）  EMD2013-108 |

| 抄録 | （和） | To study the molten bridge phenomenon of contacts at the initial breaking process, an experimental device of molten bridge between slowly opening contacts was developed. The system consists of the contact moving control module, the circuit load and the observation module. The molten bridge of copper contact under two load conditions 9V/19A and 9V/7.3A were studied. The voltage and current characteristics curves of Cu molten bridge were extracted and the resistance and the instantaneous power of the molten bridge were analyzed. The image of the Cu molten bridge diameter was captured by CCD under 9V/19A and the influences of the contact force and the separation speed on the molten bridge length and the crater diameter of the anode were studied. The root profile of the Cu contacts after separation was analyzed by digital microscope. Research results show that the Cu molten bridge length has the same changing trend as the diameter of the anode crater. They both decrease with the increment of the separation speed and the decrement of the contact force. |
