| 摘 要： | 为了降低避雷器的残压,从而降低其拐点电压,使避雷器荷电率升高。由于不同荷电率下,阻性电流占全电流的比例不同,检测的标准不同。笔者通过对不同型号的避雷器用电阻片(MOV)测量不同荷电率下电流、电压的关系,还得出不同型号、不同配方的MOV在相同荷电率下的阻性电流占全电流的比例不同,为避雷器在线监测提供依据

| Abstract: | At present,some MOA researcher try to reduce residual voltage the knee point voltage to get the ideally the knee point voltage.Because the percentage of resistive current to the total current under different charged rate is different,so the standard of inspection is different.Through measuring different types MOV′s relationship of current and voltage under different charged rate,it is also got that the percentage of resistive current to the total current of different types and different recipes MOV are different and the basis of MOA′s on-line monitoring is provided. |
