Effects of current on human beings and livestock - Part 2: Special aspects 当前对人类和家畜的影响 - 第二部分:特殊方面
发布日期: 2019-05-14
IEC 60479-2:20 19描述了当频率范围高于100 Hz的正弦交流电通过时对人体的影响。电流通过人体对以下方面的影响: -具有直流分量的交流正弦电流, -具有相位控制的交流正弦电流,以及 -具有多周期控制的交流正弦电流 给出,但仅被认为适用于从15 Hz到100 Hz的交流频率。 给出了将纯正弦波的适用频率扩展到150 kHz的方法,补充了IEC 60479-1中的数据,并给出了检查随机复杂不规则波形的方法。 该文献描述了以单个和多个连续的单向矩形脉冲、正弦脉冲和由电容器放电产生的脉冲的形式通过人体的电流的影响。规定的值被认为适用于0.1 ms至10 ms(包括10 ms)的脉冲持续时间。 与IEC 60479-1一样,本文件仅考虑由电流源直接施加到身体上产生的传导电流。它不考虑由暴露于外部电磁场引起的体内感应电流。本基本安全出版物主要供技术委员会根据IEC指南104和ISO/IEC指南51中规定的原则编写标准时使用。它不适合制造商或认证机构使用。技术委员会的职责之一是在适用的情况下,在编制其出版物时利用基本安全出版物。除非相关出版物中特别提及或包含,否则本基本安全性出版物的要求、试验方法或试验条件将不适用。本第一版取消并取代IEC TS 60479-2:20 17。本版构成技术修订版。本版本包括以下与IEC TS 60479 2:20 17相关的重大技术变更: a)从技术规范到国际标准的地位变化。
IEC 60479-2:2019 describes the effects on the human body when a sinusoidal alternating current in the frequency range above 100 Hz passes through it. The effects of current passing through the human body for:
– alternating sinusoidal current with DC components,
– alternating sinusoidal current with phase control, and
– alternating sinusoidal current with multicycle control
are given but are only deemed applicable for alternating current frequencies from 15 Hz up to 100 Hz.
Means of extending the frequency of applicability of pure sinusoids to a frequency of 150 kHz are given, supplementing the data in IEC 60479-1 and means of examining random complex irregular waveforms are given.
This document describes the effects of current passing through the human body in the form of single and multiple successive unidirectional rectangular impulses, sinusoidal impulses and impulses resulting from capacitor discharges.
The values specified are deemed to be applicable for impulse durations from 0,1 ms up to and including 10 ms.
This document only considers conducted current resulting from the direct application of a source of current to the body, as does IEC 60479-1. It does not consider current induced within the body caused by its exposure to an external electromagnetic field. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.
This first edition cancels and replaces IEC TS 60479-2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TS 60479 2:2017:
a) change in status from Technical Specification to International Standard.
