摘　　要：分析电容柜在谐波状况下元器件损坏的原因,提出采用过零触发、无触点开关合闸克服谐波引起瞬时过电流烧毁元器件的问题,采用两组电容分时投入,克服稳态谐波产生过大电流有效值引起元器件过热烧毁问题。采用上述方法,可保证电容柜在谐波状况下安全可靠运行。The reasons for the breakdown of units under harmonic conditions are analyzed, and the no contact switch and the zero trigger should be selected used to overcome problems resulting from a temporary over current breaking the units. Using two sets of capacitors crossed to overcome rises by the bigger stable harmonic current break units are suggested. Under harmonic conditions, the capacitor panel is safer and more reliable. The operation can be conducted using this method.
