摘要
焊弧是大功率的用电负载 ;手工电弧焊中焊工距焊弧较近。研究焊弧的电磁兼容问题是有实际意义的。本文分析了焊弧的形成机理 ,论述了焊弧电磁辐射的计算方法 ,给出了三维图形 ,对焊弧的辐射进行了测量 。
Welding arc is a power load and welding workers are nearer to the arc when they are working. So the research on arc's EMC is essential. Here mechanism of welding arc is analyzed, the calculation of electromagnetic radiation of welding arc is discussed, and some triaxial figures are given. Furthermore, measurements to the radiation are performed and the comparison is made to the conclusions all the above.
