摘　　要：为了进一步了解高压输电线路下工频电场对人体内部的影响,使用Pro/Engineer软件建立了带有心脏的人体三维模型。利用该模型,基于ANSYS软件仿真了考虑人体内血液和不考虑人体内血液两种情况下人体和心脏的内外部电场分布,并在此基础上计算了人体总感应电流和心脏感应电流密度。计算结果表明:人体总感应电流为66.3μA,心脏感应电流密度为33.6μA/m2,在国际非电离辐射防护委员会制定的安全限值内;考虑人体内血液时,心脏内部的电场强度增大,而人体外部电场强度减小。In order to further understand affect on human body by working frequency electric field of high voltage power transmission lines, PRO-E software was used to build a 3D human body model with heart. By using this model and on the ba- sis of ANSYS software, inside and outside electric field distribution of human body and the heart under conditions of consid- ering and disregarding blood inside human body was simulated, furthermore, total induced current of human body and in-. duced current density of the heart was calculated. Calculation results indicate that total induced current of human body is 66.3 μA and induced current density of the heart is 33.6 μA/m^2 which are both within safe limit values range formulated by International Commission on Non-ionizing Radiation Protection. Meanwhile, when considering of blood inside human body, electric field intensity inside the heart increases while electric field intensity outside human body decreases.
