Simulation Analysis of Induced Electricity During Climbing and Grounding of Weather Resistant Steel Pole Towers
摘要
Weather-resistant steel pole tower has great application space in the field of power engineering construction. However, there is a dense rust layer with high resistance value on its surface, which makes the pole tower in a bad conductor state. Inspection personnel in the maintenance can not be effectively grounded on the outage conductor, easy to electrocution hazards. In this paper, with the same tower and double-back transmission line single-loop outage work as the research object, through the electrostatic field simulation, analyzed the induced voltage of the maintenance personnel in different positions of the weathering steel pole tower; put forward a new type of weathering steel grounding wire design scheme, extracted the distributed capacitance of each part of the grounding circuit, established an equivalent circuit model of the outage conductor hanging grounding wire, and obtained the transient current when the outage conductor is hanging grounding wire. The transient current is obtained when the grounding wire is suspended from the outage conductor, and the anti-electrocution grounding scheme for the maintenance operation of weathering steel tower is finally formed. The results of the study can provide a reference for optimizing the weathering steel tower grounding repair process.
