摘要
设计了一款可用于触发和自触发的针板型电晕稳定开关,其中针电极直径为2 mm,主间隙距离为10 mm,触发间隙为5 mm。通过静电场的模拟得知其场强的不均匀系数大于7,并且通过大量实验数据得出:开关起晕电压和击穿电压分别为6.8 kV和19.3 kV,由此得知电晕稳定开关的电晕稳定因子为0.55,这说明开关具有较好的电晕稳定性。
A triggered and self-closing rod-plane corona stabilized spark switch is reported. Its rod electrode diameter, main gap and trigger gap are 2 mm, 10 mm and 5 ram, respectively. The degree of field divergence is known to be larger than 7 by simulating electrostatic field of the switch. Experimental results show that, the corona onset voltage and breakdown voltage are 6.8 kV and 19.3 kV, respectively, based on which the corona stabilized factor is caculated to be 0.55. That is, the switch has good corona stabilized performance.
