| 摘 要： | 天广直流输电工程广州换流站换流器交流侧MOA运行时,其泄漏电流值偏高,且不稳定,最高峰值达15mA。分析认为,泄漏电流偏高与直流输电换流装置产生的谐波,直流负荷的调整以及设备污秽较严重有关,并不是避雷器受潮或老化引起的。故应加强对避雷器的监视,合理利用停电机会,妥善安排各种检测项目,及时清理污秽,以免对设备造成不良影响。 |

| Abstract: | The leakage current of surge arrester used in a.c. system of Guangzhou converter station of Tian-Guang HVDC transmission project is high up to 15 mA, and not stable during operation. It was found that the high leakage current is related to harmonics produced by converter, load regulation and heavy pollution of apparatus but not caused by damp or deterioration. Based on this, it is proposed to enhance MOA monitoring, proper arrange preventive inspection in period of power cut and intime cleaning off pollution. |
