摘　　要：通过对河南电网某220 kV变电站的测试和分析,找出了无功补偿电容器(C2)频繁烧保险的原因在于5次谐波电流过载。通过调整电容器回路的参数,减少了其中的谐波电流含量,从而保证了电容器的正常运行。By analyzing and testing the harmonics at a certain 220kV station in Henan power network, the reason of the frequent fusion of the capacitor fuse was found out. It is that the 5th harmonic current was overloaded. By adjusting the parameters of the capacitor loops, the harmonic content of current in the capacitor is reduced and the capacitors can run safely.

关 键 词：电容器 谐波电流 串联谐振
