Research on electrocution protection for wading repair of electric power during extreme rainy season flooding
The regional extreme climate is complex in China,the power equipment in some areas in the rainy season waterlogging will fail or even leak.In order to solve the problem of electric shock in water-logging condition,firstly,the human safety potential is theoretically analyzed to obtain the threshold of human safety potential and to clarify the mechanism of human shock.Secondly,the finite element analy-sis software was used to establish the water dispersion model and the human electric shock model during the wading repair of electric power,to calculate and analyze the influence rule of wading depth on human body potential and cardiac potential,and to simulate the internal and external potential distribution of protective clothing under different protection states.Finally,the human potential distribution under dif-ferent protection conditions is verified by simulation test.The results of this study can provide reference for solving the problem of human electric shock caused by wading repair of electric power.
