Simulation Study on Potential Distribution Characteristics of Backfilling Water in Distribution Room

Aiming at the problem of electrocution casualties of personnel in emergency repair after water flooding in underground distribution room caused by rainstorm weather, finite element simulation software was used to establish the water dispersion model in underground distribution room, calculate and analyze the influence of water medium and other factors on potential distribution, and obtain the potential distribution rule under the condition of water accumulation. The simulation results show that when connecting zones are installed around the distribution room, the water potential changes from 285.76 V without connecting zones to 48.14 V. With the water depth changing from 0.1 to 0.8 m, the water potential increased by 10.8%. The research results are of great significance for reducing electric shock casualty rate and ensuring underground production safety.
