摘　　要：为了提高非转移型等离子弧发生器的功率和耐用度,提出了一种具有辐散式喷嘴等离子弧发生器。用这种喷嘴结构,对非转移型等离子弧进行了实验研究。与圆拄形阳极喷嘴相比较,等离子弧电压降低了3.2~9.1 V,而稳定工作的弧电流可增大到200A。Newly designed divergent nozzle anode were developed in order increase a jet power and an operating duration time of the fored constricted type plasma jet generator. The characterics of the arc and plasma jet were studied experimentally with the nozzle configuration. The arc voltage decreased by 3.2-9.1 V compared with that of a cylindrical nozzle anode, but a stable operating arc current expand up to 200 A.
