| 摘要: |
| 通过对发电厂，变电所直流系统及其绝缘监察装置的分析研究和实际应用调查发现，该装置存在两个自身无法克服的缺陷，从而提出运用计算机技术和信号检测技术在直流系统中另低频变流小信号并跟踪其变化的微机选线式直流系统绝缘监察装置，以克服现有装置的致命缺陷。 |

| Abstract: |
| Based on the analysis and application investment of direct current system insulation supervisory device of power station and substation,two defects has been found which can't be resolved by itself.In order to remove the fatal defects,a direct current system insulation supervisory device with microcomputer line detection is proposed,which injects small AC signal with low frequency into direct current system and follows up its change by computer technique and signal detection technique. |
| Key words: direct current system,insulation,grounding,supervisory device |
