| 摘 要： | 本文介绍一种封闭母线对计算机电磁干扰计算方法。通过计算母线在三相短路时的剩余电流，从而导出母线壳外磁场强度。按计算机场所防电磁干扰的要求，进一步计算出母线相对计算机场所的最小允许距离。以此校验母线及计算机场所布置，可保证计算机长期安全运行。此法将为工程设计人员提供设计依据和计算方法。

| Abstract: | This paper deals with a method to calculate electromagnetic field interferene with computerfrom strong current enclased bus. By calculating bus surplus current in 3-phase short-circuit,the magnetic field intensity outside bus case can be obtained.According to requirements of preventing electro-magentic interference of computer site,the minimum allowable distance between enclosed bus andcomputer site can be determined by this computational method. |
