Simulation Experiment And Modeling Of Electric Shock Human Body Suffered In Ionized Electric Field

With the steady improvement of China's economy,the demand for electricity in various regions is increasing day by day.However,the distribution of energy and load in China is not uniform.In order to develop the national economy rapidly,it is necessary to build long-distance and large-capacity transmission channels to connect energy center and load center.However,limited by land resources,the construction of transmission line projects will inevitably be close to densely populated areas,resulting in electromagnetic environment problems caused widespread concern.This paper focuses on the transient electric shock caused by human body moving in the synthetic electric field near the HVDC line.In order to obtain the characteristics of the human body affected by the synthetic electric field of HVDC transmission lines,the simulation model of the circuit is established and the actual situation is analyzed on the basis of the characteristic experiment of the transient electric shock platform built in the laboratory.Firstly,this paper introduces the mechanism of transient electric shock and the equivalent model of objects under human contact line,and on this basis,conceives the experimental content and designs the experimental model.By erecting wires in the laboratory and charging with high voltage DC power supply,the DC synthetic electric field environment is built,the transient electric shock experimental platform and measurement system are built,and the experimental equipment and equipment involved are also designed.The parameters are introduced in detail.Secondly,using the experimental platform of transient electric shock,the experiment was carried out in the DC synthetic electric field environment in the corona laboratory,and the synthetic electric field produced by the unipolar high voltage DC conductor was measured.At the same time,the data of transient electric shock discharge current and model potential change under different experimental conditions were collected,and a large number of repetitive experiments and comparative experiments were carried out to obtain the experimental results in the laboratory.The characteristics of transient electric shock in synthetic electric field environment under unipolar DC conductor.Finally,on the basis of the experiment of transient electric shock characteristics,a circuit model of transient electric shock simulation is established,and compared with the experimental results,the validity of the simulation model of transient electric shock is verified.Then,the actual situation of transient electric shock of metal objects under human contact line is calculated and analyzed.The transient electric shock of human body under DC transmission line is analyzed and the electric shock of human body is evaluated.
