Abstract(in English) | Arc voltage waveform, arc current waveform, Ag II (243.78nm) spectrum intensity, and Ag I (328.07nm) spectrum intensity are measured for Ag break arc, under the condition where source voltage E= 6~48V, load inductance L= 0, 2.3 mH , and closed contact current I_0= 0.6~6A. Spectrum intensity of Ag II (ion) becomes maximum value near the gaseous phase transition point, and it gradually decreases in the gaseous phase. The spectrum intensity of Ag I(excited atom) increases until gaseous phase transition point. After the gaseous phase transition, Ag I becomes constant value which does not depend on the circuit condition. Furthermore, in the boundary closed current at which transition ratio to gaseous phase is 50%, it is clarified that the average spectrum intensity of Ag II has constant value without depending on the circuit condition. Therefore, transition to gaseous phase is made when the mean number of Ag ion in metallic phase exceeds certain value. |
