摘要
制作了大型浮顶储罐的等比例模型,研究了储罐模型浮顶在直击雷作用下,使用1根和6根铜编织带时储罐浮顶中心、浮顶边缘、罐壁及罐底各点对地电压分布情况,还使用有限元电场分析软件对储罐罐体以及浮顶上的电压分布进行了计算.结果表明,增加铜带数量可以有效降低浮盘和罐壁间的电位差,从而在一定程度上减少电火花的产生.
The scale-down tank model was set up in the laboratory,and the author measured the potential distribution of the center and edge of roof,as well as the wall and bottom of tank under direct lightning strike using one and six pieces of copper strips respectively.Then the voltage of tank and roof was calculated by the finite element analysis software.The results showed that the increase of copper strip could effectively reduce the potential difference,which could reduce the spark to some extent.
