基于真实外形人体模型的非均匀电磁场曝露评估
Exposure Assessment of Non-uniform Electromagnetic Filed Based on Realistic Human Model
摘要
Abstract
To realize long-distance electricity transmission,staffs in electric utility need to work long time under high level electromagnetic field.However,excessive exposure will harm human health.Therefore,exposure assessment of electromagnetic field is very important in the development of new energy technologies.For the current exposure assessment methods,the calculation cost of voxel hmnat model is very high,and insufficient attention is paid to the non-uniform electromagnetic field in real working condition.This paper proposes two practical methods for assessing the exposure of non-uniform electromagnetic fields.A realistic human body model is established,and the correctness of the model is verified.Equivalent uniform electromagnetic field is obtained by comparing the maximum electromagnetic field level which people is exposed to and the corresponding induced electric field in human body.The spatial average of exposure through the whole body is determined by arithmetic mean averaging and quadratic mean averaging,respectively.An assessment example of non-uniform magnetic field exposure around air-core reactor is given to demonstrate the effectiveness of the equivalent uniform electromagnetic field approach and the spatial averaging approach in assessing non-uniform exposure based on realistic human body model.关键词
