We measured the spectrum-line intensity distribution during arc discharging for each electrode. It was found that for Cu, CuCc CuBi, and AgWC electrodes, the total of the spectrum intensity from 300nm to 900 (i.e. evaporation quantity) increase in the order of Cu, CuCc CuBi, and AgWC, and the chopping current decrease in the same order. The spectrum intensity of pure Cu and Cu alloy was investigated. It was found that the intensity peak (Um) decrease in the order of Cu, CuCr and CuBi, but the chopping current did not increased in the same order. It decreased in the same order with the decline speed of the intensity (dU/dt). The chopping current is mainly determined by the evaporation quantity and the thermal properties of the additives in Cu alloy. We also observed the intensities during arc voltage oscillating for each electrode. It was found for every electrode that the oscillation voltage rises to the same direction with the arc voltage, and the spectrum intensity sharply decreases at the arc voltage oscillation. It supports the view that spotless discharge (a kind of glow discharge) occurred during this period.","PeriodicalId":137370,"journal":{"name":"XXIst International Symposium on Discharges and Electrical Insulation in Vacuum, 2004.

A wire-plane electrode arrangement has been chosen, as an example. The invariability of the electric Intensity force lines In the case of corona discharge in comparison with the case without discharge Is a fundamental assumption of this algorithm. So the distribution of electric intensity in the case of the corona discharge E cor along a force line can be expressed by the formula E cor = S E el , where E el is an electric intensity in the case without discharge, S is a some scalar function of coordinates. The computational algorithm consists of several stages. At the first stage the electric field distribution without taking into account a volume charge was calculated. At the following stage force lines were constructed and distributions of a volume charge and an electric field at corona discharge was calculated along these lines. Further, the current density distribution was specified so that drop of potential along whole force line was equal to the applied voltage, and new calculation was made with the specified value of a current. As these tasks are non-standard for ANSYS package, special programs were developed for their calculation in this package. At last stage the accuracy of received solution was estimated. Estimation has shown the solution satisfies to the Initial equations of corona discharge with accuracy about 10-15 %. Then calculated density of electric forces was used for the electric wind task solution, therefore pressure and velocity distributions were received.","PeriodicalId":137370,"journal":{"name":"XXIst International Symposium on Discharges and Electrical Insulation in Vacuum, 2004.
