摘 要:介绍了从俄罗斯引进的用于交变磁场的国防标准——交变中磁标准装置的基本工作原理,以及对其设计方案的剖析。该标准装置工作频率(20~1 000)Hz,复现交变磁场强度(0.1~1 000)mT,在这一领域内代表国际最高水平。通过对其信号获取、磁场感应信号的放大处理、大电流的产生办法、安全互锁设计,以及整体系统理论计算的分析,为该领域内标准装置的国产化提供理论基础,具有较好的实用价值。[著者文摘]
An Analysis of a Standard Set from Russia for Moderate Intensity AC Magnetic FieldZHAI Jing-jing YANG Yun No.710 R&D Institute,CSIC,Yichang 443003Abstract:In this paper,a standard set from Russia in moderate intensity AC magnetic field is researched.The magnetic field this standard set can produce is(0.1~1 000)mT,(20~1 000)Hz.So,in order to design the standard set by ourselves the standard set's method to obtain signal,way to deal with the induction signal,system to produce big circuit,safety system and the whole set's theorefical coumputation are analyzed.All these are preferably practical.[著者文摘]
