Comparison of DC breakdown characteristics and ionization capabilities of button-type metal diverter strips
摘要
Abstract
[Objectives]To enhance the effectiveness of button-type metal diverter strips in ship-radome lightning protection,their ionization characteristics should be investigated under conditions simulating the vi-cinity of approaching lightning leaders.[Methods]We present the experimental results of DC breakdown voltage for button-type diverter strips with various button spacings,button shapes,and diverter strip lengths,for comparing their ionization capabilities.Accordingly,we performed electrostatic field distribution calcula-tions for the corresponding strips.[Results]Our experimental results show that,with increasing diverter strip length,the breakdown voltage of diverter strip exhibits saturation.For a fixed diverter strip length,a lar-ger spacing between metal buttons results in higher breakdown voltage.Moreover,the breakdown voltage of elliptical-button diverter strip is the lowest,roughly 77%of that of circular-button diverter strips.Furthermore,the breakdown voltage of rectangular-button diverter strips is about 86%of that of circular-button diverter strips.Our electrostatic field calculations suggest that the electric field intensity distribution of button-type di-verter strip is relatively high at both ends and low in the middle,and that the smaller the spacing between but-tons,the higher electric field strength at the gap near both ends.Compared with the circular-button and rectan-gular-button diverter strips,the electric field strength at both ends of the elliptical-button diverter strip is the highest.The electric field strength between the two ends of the diverter strip gap decreases nonlinearly with the increasing diverter strip length,thus explaining the variation in breakdown voltage observed in the experi-ments due to differences in button shapes and specifications.[Conclusions]Results provide a basis for the optimization of button-type metal shunt strips,thereby enhancing the lightning protection performance of radomes.关键词
