HL-2A装置欧姆电源的变流器状态检测器

Converter Status Detector for Ohmic Heating Power Supply of HL-2A

简要介绍了HL-2A装置的欧姆电源系统及其逻辑无环流工作方式,其中变流器状态检测器通过测量每个晶闸管的开通或关断状态来判断变流器的输出电流是否为零。由于第一版检测器的精度和可靠性并不高,为此对检测器进行了改进并给出了实验结果。目前第二版的检测器取得了较好的性能,响应时间约为1ms,并且在电源工作异常的情况下也能准确反映变流器的状态。

The ohmic heating power supply of HL-2A and the operation mode without circulating current are introduced. The principle of the converter status detector is given,h monitors the turning on and turning off statuses of each thyristor to show whether the output eurrent is zero,Because the accuracy and reliability of first generation of converter status detector are not very high ,the improvement on the second generation of detector has been carried out and the experimental results are given.Now the second generation detector gets better performance.The response time can be 1 ms,and the detector can reflect the status of converter accurately even in some accidents.
