标准摘要
[中文适用范围]： IEC 61643的本部分适用于针对雷电或其他瞬态过电压的间接和直接影响的浪涌保护设备。这些设备经过封装可连接到 50/60 Hz 交流和直流电源电路，并且设备速率 [外文原描述]： This part of IEC 61643 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are packaged to be connected to 50/60 Hz a.c. and d.c. power circuits, and equipment rated up to 1 000 V r.m.s. or 1 500 V d.c. Performance characteristics, standard methods for testing, and ratings are established for these devices that contain at least one nonlinear component that is intended to limit surge voltages and divert surge currents.
