标准摘要
[中文适用范围]： IEC61643 的这一部分描述了连接到 50 Hz 至 60 Hz 交流和直流电源电路和额定电压高达 1 000 V rom.s 或 1 500 V dc 的 SPD 的选择、操作、位置和协调原则。 1 对于电力牵引等特殊应用，可能需要附加要求。 注 2 应记住，IEC 60364 系列和 IEC 62305-4 也适用。注 3：本标准仅涉及 SPD，而不涉及设备内部集成的 SPD 组件。 [外文原描述]： IEC 61643-12:2008 describes the principles for selection, operation, location and coordination of SPDs to be connected to 50 Hz to 60 Hz a.c. and to d.c. power circuits and equipment rated up to 1 000 V r.m.s. or 1 500 V d.c. Specific change with respect to the previous edition is the incorporation of Amendment 1, which was not published separately due to the number of changes and pages.
