内容記述 | This experiment was applied to spectroscopic method for a short arc of Ag and Ag-CdO contacts at the breaking and was measured the change of the intensities of spectral lines with the number of times of the make and break. The number of times of the make and break did up to the 50000 times. The arc temperature was calculated by the ratio of one pair of Agl lines at the thermal equilibrium in the arc column. The temperature is between 3000oK and 50000K under ordinary condition, however, it changes with the number of times of the make and break. The change of the arc temperatures have some penodical character and shows the peak value between 15000 and 25000 times for Ag contact, 20000 times for Ag-5#CdO contact, 25000 times for Ag-15SCdO contact. Considering Ag and Cd atoms in the arc column, the change of Ag atoms are in good agreement with the change of the arc temperature. Bisides, at Ag-CdO contact, it also is confirmed with the spectroscopic that Cd atoms evaporate earlier than Ag atoms. | |||||
