Abstract

Abstract:

With the continuous improvement of the voltage level of transmission line, people pay more and more attention to the power frequency electromagnetic field problems. This paper analyzes the power frequency electric field effects of simplified human body model in 750kV AC transmission lines. In order to compare the distribution of induced electric field of human body with different postures, prolapsing and lifting of hands, taking an umbrella and walking human body model is built. Taking both hands prolapse model as an example, we study the influence of the height from the ground to the overhead transmission line on human electric field effect. The simulation calculation results show that the existence of human body will change the distribution of the electric field near the ground. There will be the maximum local field strength near the head, ear and shoulder of human body. The change of body posture will affect the distribution of induced electric field and the maximum local field strength always appears in the contour parts of human body. The higher the wire above the ground is, the smaller the electric field value on human body is. It can be concluded that the maximum local field strength of human body model in different postures is still within the numerical range of health and the power frequency electric field of 750 kV UHV transmission line won't cause harm to human body health.

Key words: 750 kV, power frequency electric field, simulation calculation, finite element method (FEM), human body model
