标准摘要
[中文适用范围]: IEC 62226 的这一部分适用于以人体暴露于电场时产生的电压或电流感应为基础的频率范围。本部分详细定义了耦合因子 K – 由 IEC 62226 系列引入,用于对复杂暴露情况(如非均匀磁场或扰动电场)进行暴露评估 – 适用于暴露于均匀电场的简单人体模型的情况。耦合因子 K 具有不同的物理解释,具体取决于它是与电场暴露有关还是与磁场暴露有关。它就是所谓的“电场形状因子”。当电场可被视为均匀时,可以使用 IEC 62226 的这一部分,频率至少高达 100 kHz。这种暴露于“均匀”电场的情况主要见于高压架空电力系统附近。因此,本部分给出的图示针对的是电力频率(50 Hz 和 60 Hz)。 [外文原描述]: Applies to the frequency range for which exposure limits are based on the induction of voltages or currents in the human body when exposed to electric fields. Defines in detail the coupling factor K - introduced by the IEC 62226 series to enable exposure assessment for complex exposure situations, such as non-uniform magnetic field or perturbed electric field - for the case of simple models of the human body, exposed to uniform electric fields. The coupling factor K has different physical interpretations depending on whether it relates to electric or magnetic field exposure. It is the so called "shape factor for electric field". This part of IEC 62226 can be used when the electric field can be considered to be uniform, for frequencies up to at least 100 kHz. This situation of exposure to a "uniform" electric field is mostly found in the vicinity of high voltage overhead power systems. For this reason, illustrations given in this part are given for power frequencies (50 Hz and 60 Hz).
