标准摘要
[中文适用范围]: 本技术报告提供了低压安装和设备的各种浪涌过电压类型的概述。特别是: - 典型浪涌的幅值和持续时间及其发生频率; - 关于电力系统和通信系统之间相互作用产生的过电压的信息; - 关于绝缘协调界面问题的指导原则; - 基于可用性和风险考虑(包括系统内的相互作用)的浪涌保护手段的指导原则; - 强调临时过电压和其他必须在绝缘协调中考虑的因素,主要与使用浪涌保护装置的防护控制有关。 [外文原描述]: IEC TR 60664-2-2:2002(E) Provides an overview of the different kinds of surge overvoltages that can occur on low-voltage installations and equipment. In particular: - the magnitude and duration of typical surges as well as their frequency of occurrence; - information on overvoltages resulting from interaction between power and communication systems; - guidelines when considering interface issues in relation to insulation coordination; - guidelines concerning surge protection means on the basis of availability and risk considerations, including interaction within the system; - highlights temporary overvoltages and other factors that have to be taken into account for insulation coordination, primarily related to protective control using surge protective devices.
