采用静电间隙放电实验研究了Ag-CdO电极的电弧侵蚀行为。通过记录每次放电的击穿电压，从而记录电极间隙距离，连续监测腐蚀深度。基于实验数据和简单的模型，确定了不同电弧能量下的侵蚀机理。低能电弧对电极的腐蚀主要是由蒸发引起的，高能电弧对电极的腐蚀主要是由熔化和烧蚀引起的。腐蚀效率估计为0.003至0.009，这表明大部分电弧能量在电极间大气中消散，并通过传导进入电极，只有一小部分电弧能量实际引起电极腐蚀。>
The arc erosion behavior of Ag-CdO electrodes has been investigated by static gap discharge experiments. By recording the breakdown voltage of each discharge, and thus the interelectrode gap distance, the erosion depth was continuously monitored. Based on the experimental data and a simple model, the mechanisms of erosion at different levels of arc energy were identified. When struck by low-energy arcs, the electrode erosion was found to be mainly due to vaporization, but when struck by high-energy arcs the electrode erosion was by melting and ablation. The efficiency of erosion was estimated to be 0.003 to 0.009, which suggests that most of the arc energy is dissipated in the interelectrode atmosphere and by conduction into the electrodes, and that only a small fraction of the arc energy actually causes electrode erosion. >
