摘　　要：分析各种典型铁磁材料抑制和消耗中性束注入(neutral beam injector,NBI)系统中分布电容故障能量的特性,搭建测试平台利用1∶10的短路放电测试实验优选出合适的材料组合,对集中式和分布式缓冲器结构进行仿真分析,推导出适用于80kV中性束实验用分布式缓冲器设计参数并进行实物研制.结果表明,所研制的缓冲器可将故障能量抑制在5J以内.In neutral beam injector （NBI） system, material to inhibit fault current and consume fault it is important to choose proper ferromagnetic energy. To find appropriate type of material, the features of some typical ferromagnetic materials were fully analyzed. The test platform was established to conduct short circuit experiment with 1 ： 10 scale for choosing the optimal material. Simulations were implemented to compare the effects of distributed core snubber with concentrated core snubber. The results show that the developed distributed core snubber could ensure 80 kV neutral beam injector system running safety and the fault energy could be limited to five joules.
