摘要
依据速调管耗散能量的安全值与最大故障电流、电弧电压和电源供电切断时间的关系,介绍了EAST上2.45 G/2 MW低杂波速调管过流保护系统的设计。采用过电流电路触发和引燃管旁路速调管电流的方法来实时保护速调管。经自检测试和在EAST放电实验中的应用表明,该系统能在50μs内完成保护,完全满足设计需求。
The energy dissipated on the electrodes of a klystron can be estimated from maximal breakdown current, value of the arc discharge voltage and time of turning off the power supply. It mainly introduces the design of over-current protection of Klystrons for 2. 45 G/2 MW LHCD System on EAST. Circuits triggering by an over-current and ignitrons are adopted to protect klystrons. Experiment results prove that the system can protect klystrons efficiently.
