Abstract
In order to investigate the influence of copper shield winding manner on the safety operation of pipe type In order to investigate the influence of copper shield winding manner on the safety operation of pipe typebusbar, this paper focused on 35kV AC sides of the busbar insulation burned down case in a 110kV substation.Accordingto the imaging of the breakdown point, the finite element simulation of the busbar was used to analyze the po -tential distribution of the semiconducting layer , current density and resistance loss density under copper shield wrapped and stacked way.The results show that the potential distribution , current density and resistance loss density are significantly different.The potential in the copper shield is high, and the current and resistance heating power density of semiconducting layer surface are large, there exist an obvious hot point when the copper shied is wrapped .The potential, surface current and resistance heating power density of the semiconducting layer are close to zero , and there is no obvious hot point when the copper shied is stacked .These features may improve the wingding way of the copper shield and provide a theoretical basis for the actual production work .关键词
