雷暴警报系统.雷电防护

[中文适用范围]： 本文件描述了雷电预警系统（TWS）的特征，以便实施防雷预警措施。单传感器和/或传感器网络（例如闪电定位系统）可用作TWS。本文件提供了收集相关参数准确数据、提供雷暴和大气电活动实时信息的传感器和网络的要求。它描述了由这些传感器和网络收集的数据以警告和历史数据形式的应用。本文件包括：可用TWS技术的总体描述；预警方法的指南；可能的预防措施的信息性示例。以下方面不在本文件范围内：a) 防雷系统：此类系统由IEC 62305（所有部分）[1]覆盖；b) 其他与雷暴相关的现象，如雨、冰雹、风；c) 基于卫星和雷达的雷暴探测技术；d) 便携式设备（传感器不固定的设备）。注意：便携式设备的校准和测试可能不足以提供有效的预警。 [外文原描述]： IEC 62793:2020 describes the characteristics of thunderstorm warning systems (TWSs) in order to implement lightning hazard preventive measures. Single sensors and/or a network of sensors (e.g. lightning location system) can be used as a TWS. This second edition cancels and replaces the first edition, published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - portable devices are no longer covered by this standard; - in Clause 5, classes of TWS have been deleted; - in Clause 6, updated figures and more detailed text are provided to better illustrate the alarm timeline; - in Clause 9, the text has been summarized and refers now to the application guide given in Annex F; - annexes have been reorganized; - Annex E is normative.
