摘　　要：通过对500kV三堡变电站的串联补偿装置的运行、操作、控制分析研究,在全面阐述电容器、MOV、触发间隙、阻尼电抗器原理的基础上,重点分析研究了外熔丝电容器与内熔丝电容器及其优缺点,指出了故障电容器元件对分布电压的影响;分析了MOV、触发间隙、旁路断路器的作用,提出了限制出现在电容器组上的过电压,保护电容器组措施,进一步确定对串联补偿装置正确的操作与控制方法。Based on the analysis ot the operation, switching and control of me series compensauon device in a 500kV substation, the principles of the capacitor, MOV, triggering gap and damping reactor are comprehensively expounded. In this paper, the capacitor with external fuse and internal fuse, the corresponding advantages and disadvantages are studied emphatically. The protection measures to restrain the overvoltage occurred in the capacitor bank are suggested. The correct switching and control methods to the series compensation device are further determined.
