摘　　要：介绍了以高压引燃管为核心的撬棒快速保护技术,它用来满足功率直流高压电源(3～30MW/35～100kV)场合下以μs级快速转移微波放大管负载故障电流的需要。通过对负载吸能极限的必要分析和对撬棒回路旁路故障能量的具体计算,选择相应的引燃管串并联方式和抗干扰触发电路,并按核聚变装置中功率速调管的保护要求给出撬棒快速保护技术线路。实验结果表明撬棒回路在32μs内可完全转移高功率微波管的故障电流。Fast protection technology of crowbar base of ignitron is described in this article which apply in the high-voltage power supply on the microwave amplifier (3-30 MW/35-100 kV), the fault current can be transfer from the klystron to the ignitron which protect the tube from arcing in a few micro-seconds, according to circuit analysis for consumption of load energy and fault energy bypassed by crowbar circuit, ignitions are series-parallel connected with certain mode as well as anti-jamming trigger circuit is adopted, to satisfy the requirement of the protection technology for klystron in fusion system, technical project and virtual experiment of the crowbar protection are given below, and the experimental result is shown that the fault current can be transfer from the klystron to the crowbar entirely in 32 μs.
