Research on Electric Shock Protection for Electric Power Water related Repair in Extreme Rainy Season Flooding

China's regional extreme climate is complex, some areas of the power equipment in the rainy season waterlogging in the failure or even leakage risk. In order to solve the problem of electric shock in waterlogging condition, firstly, the human safety potential is theoretically analyzed, the threshold of human safety potential is obtained, and the mechanism of human shock is clarified. Secondly, the finite element analysis software was used to establish the water dispersion model and the human electric shock model during the electric power wading repair, and the influence rule of wading depth on human potential and cardiac potential was calculated and analyzed, and the internal and external potential distribution of protective clothing under different protection states was simulated. The results of this study can provide reference for solving the problem of human electric shock caused by water rush repair.
