摘要
将高压脉冲引弧所产生的干扰小和高频高压振荡引弧时的引弧成功率高相结合起来,实现一种低频高压脉冲引弧方式。介绍低频高压脉冲引弧方式的工作原理和参数选择,并通过实验测试发现,该引弧方式产生的干扰小,引弧成功率高。
A low frequency higb vohage pulse arc ignition mode is introduced in this paper,it combines the small interference generated by high voltage pulse arc ignition and the high success rate of arc ignition in high frequency and high voltage oscillating arc ignition. The working principle and parameter selection of this mode are introduced ,and the test results show that this mode generates small interference and high success rate.
