| Abstract(in English) | We have studied Maintaining mechanism of the contact arc discharge. For this object, the spectrum measurement system was composed using two monochromators and a bifurcated image fiber. Arc voltage waveform and W II (239.71nm) spectrum intensity are measured for W break arc, under the variation of closed contact current Io (1～6A), source voltage E (48, 12V), and load inductance L (0, 2.3mH). From comparison of arc voltage waveform and time-varying tendency of spectrum intensity, it is clarified that spectrum intensity of W II continuously increase in metallic phase arc region. Furthermore, relationship between the average spectrum intensity Itm for metallic phase region and Io is investigated. As a result, over the closed current at which transition from metallic to gaseous begins, increasing slope of Itm to Io becomes large. |
