多芯电缆耦合外界强电磁场规律研究
Research on the laws of multi-core cable coupling with external electromagnetic field
摘要
Abstract
Cable is usually used to transfer control or communication signals, and often interfered by external electromagnetic field. In order to research the laws of multi-core cable coupling with an external electromagnetic field, MTL equations are decoupled by matrix similarity transformation method, then the time solutions of the induced currents are gotten by fast Fourier transform technique. The factors that affect the induced currents such as cable length, height, earth parameters, incidence angles of EMP and conductance of cable core lines are analyzed. By comparison with correlated method, the implement of algorithm in present paper is simple, and it is convenient to be used on the research of cable coupling with electromagnetic field. The results in present paper has some reference value in electromagnetic protection of cables used by electric power, communication, etc.关键词
