摘　　要：通过对大功率长寿命等离子体炬的基本特性的深入了解 ,得到了一套完整的等离子体炬运行参数。制成的等离子体炬功率在 80～ 2 5 0 k W之间可任意调节 ,弧电压最高达到 490 V,热效率最高达到 73% ,等离子体射流长度大于 40 cm。研制的等离子体系统运行稳定 ,性能可靠 ,阴极烧损量仅为 4.1ng·C- 1。该等离子体炬已成功地应用于三废处理实验中 ,运行时间已超过 10 0A complete set of plasma torch operating parameters is obtained through deep going understanding of the basic properties of a high power arc plasma torch with long life. The completed plasma torch has an adjustable power in the range of 80～250kW with arc voltage up to 490V, thermal efficiency up to 73% and jet length more than 40cm. The plasma torch system operates stably and reliably, and the cathode burnup is only 4.1ng·C -1 .This plasma torch has successfully operated in waste disposal experiments for more than 100 hours.
