辅助加热高压电源是国家863高技术项目,可分别为低混杂波驱动、中性束注入、离子回旋等辅助加热系统供电。它由两组电源组成,并联设计输出±40kV、72A,串联设计输出±70kV,36A。该电源于1994年基础安装调试完毕后,在年度物理实验中曾多次为中性束注入、低混杂波驱动供电。在1998年的HL-1M装置运行中,本电源连续进行4次、50kV、20A、1300ms的放电。在持续时间、重复性、稳定性方面都达到了历年来最高水平,这主要得益于最近投入使用的高压电源微机反馈调节控制系统。另外,配套完成的微机采集系统可在每次放电后数秒得到本次放电所需8个工作点的电压、电流波形。这对各主要设备的工作状态有了即时了解,提高了实验效率。
Auxiliary heating of high-voltage power supply is a national 863 high-tech projects, which can be low mixed-noise drive, neutral beam injection, ion cyclotron and other auxiliary heating system. It consists of two sets of power supply, parallel design output ± 40kV, 72A, series design output ± 70kV, 36A. The power supply in 1994, the basic installation and commissioning is completed, the annual physical experiments have repeatedly for the neutral beam injection, low hybrid noise-driven power supply. During the operation of the HL-1M unit in 1998, the power supply was continuously discharged 4 times at 50kV, 20A and 1300ms. In the duration, repeatability, stability has reached the highest level in years, mainly due to the recently put into use high-voltage power supply microcomputer feedback control system. In addition, the complete computer acquisition system can be discharged in a few seconds after the discharge required for the 8 operating voltage and current waveforms. This has an immediate understanding of the working status of the major equipment and improves the experimental efficiency.
