电流对人和牲畜的影响.第4部分:雷击的影响

[中文适用范围]： 本部分IEC 60479概述了雷电及其变异性涉及人类和牲畜的基本参数。指出了雷电对人体和牲畜身体的可能直接和间接相互作用。描述了雷电电流对生物体产生的后果。本文件显示了由于雷电击打而对人类和牲畜产生的影响与来自电气系统的电击产生的影响之间的差异。 [外文原描述]： IEC TR 60479-4:2020 (E) summarizes the basic parameters for lightning and its variability insofar as they apply to human beings and livestock. The possible direct and indirect interactions of strikes with bodies of living beings are indicated. The resulting effects caused by lightning currents for the organism are described. This document shows the differences of effects on human beings and livestock due to lightning strokes versus those effects of electric shocks derived from electrical systems. This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) lightning occurence and climatory effects around the world are depicted; b) direct strike description is extended; c) step voltage effects are expanded; d) upward streamer explanation is enhanced; e) other direct or indirect related effects to lightning injuries to the human body are specified; f) various safety procedures and related possibilities with respect to the personsal danger of lightning are presented.
