摘要
通过直流电晕放电将正、负极性电荷附到绝缘子表面 ,然后将电压从直流快速切换成雷电波或陡波 ,研究 SF6气体中绝缘子沿面闪络特性。实验结果表明 。
The positive or negative charges is injected into the spacer surface by DC corona discharges, and the flashover characteristics are investigated by a sudden change from DC to lightning or steep fronted impulse in presence of a conducting particle attached on spacer in SF 6. Experimental results shows that the polarity of surface charges has a great influence on impulse flashover voltages.
