摘要：

介绍了 HL-2A装置低杂波加热系统中的低压部分实时保护系统的原理和工作情况。实时保护电路工作可靠, 系统低压部份响应延迟时间小于 1μs。在 2004年的单只速调管实验中, ,速调管管体电流和速调管集电极过流进行了实时保护, 各个保护对象都有专用的探头进行测量, 其中管体电流探头精度达到 0. 7%。实验信号的分析表明保护系统的设计达到了实验要求, 有效地保护了实验对象。

关键词: 拉弧打火, 管体电流, 过流

Abstract:

The principle and operation of the low-voltage real-time protection system for the lower hybrid current drive (LHCD) system on HL-2A tokamak has been presented. The real-time protection is carried out by hardware circuits which must be reliable with response time less than 1μs. The real-time protection for wave guide arcing protection, klystron body-current protection and over-current protection of klystron collector had been realized in the LHCD experiments using single klystron in 2004. Special detector for each protected target was used . The precision of body-current detector reaches 0. 7 %. The protection system works reliably.

Key words: Arcing , Body-current , Over-current
