摘要
本文金属钮扣式分流条的雷电防护能力与其在雷电环境中的击穿特性密切相关,而这种分流条的击穿特性决定于其纵向电场分布特性。本文可以为钮扣式分流条用于雷达罩的雷电防护提供理论参考。借助于有限元分析软件,对钮扣式分流条的纵向静电场分布进行仿真研究,研究金属钮扣间隙的长度、钮扣的形状和绝缘基带相对介电常数等因素对其纵向电场分布的影响规律。结果表明:金属钮扣式分流条钮扣间隙的电场分布以中间间隙为中心两侧对称分布,且呈现两边高、中间低的分布特点。间隙电场随着间隙长度的增大而减小;金属钮扣的形状,会影响纵向电场的分布,长方形钮扣间隙的电场强度低于椭圆形;绝缘基带的相对介电常数对钮扣间隙的电场分布有影响,相对介电常数越大,电场分布越趋于平缓。结论为金属钮扣间隙长度、钮扣的形状、基带的相对介电常数对金属钮扣式分流条的纵向电场分布都有影响,在进行分流条的设计时,应着重考虑。
The lightning protection ability of the metal button diverter strips are closely related to its breakdown characteristic in the environment of the lightning,and the breakdown characteristics of this kind of diverter strips depend on their longitudinal electric field distribution.The results of the study for the button diverter strips used for radome can provide the theory reference for radome lightning protection.The simulation research about the longitudinal electric field distribution of the button diverter strips have been done by The Finite Element Analysis Software.The research is about the influence on longitudinal electric field distribution by the length of the metal buttons’gaps,the shape of buttons,the and the relative dielectric constant of insulating baseband.The distribution of gaps’electric field of the metal button diverter strips centers on middle gap and is bilateral symmetry.Its electric field is high on both sides and low in the middle.The gaps’electric field decreases with the increase of gaps length.The shape of the buttons affect the distribution of longitudinal electric field.The electric field intensity of rectangle buttons’gaps is lower than the oval.The relative dielectric constant of insulating baseband influence the distribution of longitudinal electric field.The greater the relative dielectric constant,electric field distribution is leveling off.All the the shape of the buttons,the length of the metal buttons’gaps and the relative dielectric constant of insulating baseband affect the distribution of longitudinal electric field.In the design of the diverter strips,they should be considered carefully.
