电极材料对碳酸丙烯酯冲击击穿性能的影响

摘要
研究了不锈钢、黄铜与铝三种电极材料对碳酸丙烯酯液体电介质冲击击穿性能的影响。实验结果表明碳酸丙烯酯的冲击击穿电压在平行板不锈钢、黄铜与铝电极对情况下依次递减。为了研究电极材料对碳酸丙烯酯冲击击穿性能的影响机理,利用克尔电光测量方法测量了三种不同电极情况下液体中电场与空间电荷的分布情况。测量结果表明,三种金属材料的空间电荷注入能力铝最强,黄铜次之,不锈钢最弱,而相应地,液体中电场畸变率在不锈钢、黄铜与铝电极对情况下依次增加。这说明了冲击电压作用下三种金属电极材料在碳酸丙烯酯中的电场畸变率差异,造成了冲击击穿特性的不同。
In this paper,the three types of metal( stainless steel,brass and aluminum) are used to study the electrode material effect on the breakdown performance of propylene carbonate under impulse high voltage. The breakdown test shows that the impulse breakdown voltage of propylene carbonate under a pair of parallel-plate electrodes made of stainless steel,brass and aluminum decreases in sequence. To investigate the electrode material effect on breakdown property under impulse voltage,the electric field and space charge distributions in propylene carbonate under the three types of electrodes are measured. The measurement results indicate that the charge injection ability of aluminum electrodes is highest,followed by brass,and then stainless steel electrodes. Accordingly,the electric field distortion rate of propylene carbonate increases in the sequence of stainless steel,brass and aluminum electrodes. This finding illuminates that the difference of electric field distortion rate among the three types of electrodes leads to the difference of breakdown performance in propylene carbonate.
