摘要
介绍了500kV梦罗Ⅰ回调试过电压的计算方法,对500kV梦罗Ⅰ回的调试过电压、避雷器吸收能量、避雷器退出运行后的操作过电压进行了计算和分析,并对避雷器能够吸收操作过电压能量和限制操作过电压的能力进行了评估,提出了防止产生操作过电压的措施。
This paper introduces calculation method of 500 kV Mengluo line I adjusting overvoltnge, calculates and analyzes adjusting overvoltage, arrester absorbing energy and operating overvohage after arrester out of service of 500 kV Mengluo line I, and evaluates the ability that arrester can absorb energy of operating overvohage and can restrict operating overvohage, proposes measure to prevent producing operating overvohnge.
