Analysis on Influence on Human Body by Compound Electric Field Strength of Ultra-high Voltage DC Power Transmission Lines
摘要
Abstract
In allusion to the problem of electric magnetic environment caused by ultra-high voltage DC power transmission lines,ANSYS software is used to established a human body model close to human body shape.Taking ±800 kV ultra-high voltage power transmission line from Sichuan Xiangjiaba to Shanghai Fengxian as an example,this model is used to simulate distribution of electric field strength inside human body under two conditions including human body ground insulation and hu-man body grounding,in addition,APDL language is used for programming and calculating different distances between hu-man body and power transmission line so as to analyze influence on human body electric field by compound electric field strength.Calculation results indicate that at the time of human body ground insulation and human body grounding,maxi-mum electric field strength values both occur under the armpit,which are respectively 27.9 mV/m and 13.6 mV/m.With changes of different distances being apart from the center of power transmission line,change of the maximum electric field strength inside human body may show a parabola curve ,and the maximum value occurs at the point of 1 8 m being apart from the center of power transmission line which is 650 mV/m and somewhat higher than the limit value of exposed electric field strength for human body under different exposed situations of high voltage power transmission lines regulated by Inter-national Commission on Non-ionizing Radiation Protection (ICNIRP).At this time the electric field strength being apart from the head is 1 10 mV/,which is within the specified limit value range.关键词
