基于回归分析的人体工频电场畸变影响分析预测研究
Research on Analysis and Prediction of Distortion Phenomena of Power Frequency Electric Field Around Human Body Based on Regression Analysis
摘要
Abstract
In order to explore the distribution pattern of power frequency electric field surrounding the human body beneath transmission lines and quantitatively analyze the distortion effect of the human body on the field strength when it is situated within the power frequency electric field,this paper takes the power frequency electric field generated by the side conductor of a 500 kV overhead line as the research object.A portable power frequency electric field measurement device is used to detect the electric field strength at various positions and distances in the vertical and horizontal directions relative to the human body,thereby obtaining the distribution pattern of the power frequency electric field around the human body beneath transmission lines.The results show that the head,shoulders,upper arms,waist,buttocks,knees and feet of the human body all have different distortion effects on the electric field strength.When the distance between the measuring position and the human body is greater than 100 cm,the distortion effect of the human body on the electric field in the surrounding air domain can be ignored.On this basis,through regression analysis of the results of the electric field strength detection at different points in the horizontal and vertical directions relative to the human body,a correction equation is obtained for the impact of different parts of the human body and different positions from the electric field center on the power frequency electric field strength,laying an important foundation for proposing protective measures for workers.关键词
