摘要
以SLYWV-75-10型漏泄同轴电缆为例,建立疏编织型漏泄同轴电缆外导体展开模型,以某一菱形孔隙为中心,分别求得4根编织线、4股编织线和8股以上编织线围绕孔隙的磁场分布公式;利用MATLAB软件模拟磁场分布.结果表明,孔隙内部靠中心位置磁场强度较小,边缘较大,且在孔隙尖端出现极值,整个磁场呈现中间较平、四周卷曲的分布图样.
Taking SLYWV-75-10 braided coaxial cable as an example,the model of conductor outside the cable has been built up in this work.The magnetic field distribution formula for the cables with four braided wires,four bunches of braided wires and eight bunches of braided wires was obtained by a diamond-shaped aperture as the center,and the distribution of magnetic field was also simulated by means of a Matlab software.The results show that the situation inside the aperture is closer to the center,the magnetic field strength is smaller.Moreover,the maximum value of the magnetic field strength occurs at the aperture tip.However,the magnetic field inside the aperture presents relatively flat and crimps at the edge.
