【摘要】：中国新能源的资源分布与需求分布具有逆向性。为实现电能的长距离传输,相关作业人员需要长期工作于高水平的电磁环境中。为防止过度曝露对健康造成伤害,电磁环境研究是发展新能源技术的重要部分之一。针对现有评估中体素人体模型计算代价高以及对真实职业电磁环境非均匀性考虑不充分,文中提出两种实用的评估方法。搭建外形真实的人体模型,验证模型的准确性;基于体内感应量极值与体表所承受的最大曝露水平确定等效的均匀电磁场;基于算术平均法与均方值平均法,确定身体各部分承受的电磁场水平平均值。通过对空心电抗器周围典型非均匀磁场的分析,证明了基于真实外形人体模型,匀场等效法与空间平均法对非均匀电磁场曝露评估的有效性。
[Abstract]:The distribution of resources and demand of new energy in China is reverse. In order to realize the long distance transmission of electric energy, related operators need to work in high level electromagnetic environment for a long time. In order to prevent excessive exposure from harmful to health, electromagnetic environment research is one of the important parts of developing new energy technology. In view of the high calculation cost of human body model and inadequate consideration of the non-uniformity of electromagnetic environment in real occupation, two practical evaluation methods are proposed in this paper. Build a real human body model, verify the accuracy of the model; determine the equivalent uniform electromagnetic field based on the maximum exposure level and the maximum exposure level of the body surface; based on the arithmetic average method and mean square average method, Determine the average of electromagnetic field levels to which all parts of the body are subjected. Based on the analysis of the typical nonuniform magnetic field around the hollow reactor, the effectiveness of the uniform field equivalent method and the spatial average method for the assessment of the exposure to the non-uniform electromagnetic field is proved based on the real human body model.
