低频高性能屏蔽装置的设计
Design of shielding device with low-frequency and high-performance
摘要
Abstract
A magnetic shielding room is designed in order to evaluate the magnetic shielding effect on low-frequency magnetic fields. A kind of shielding scheme is proposed,in which the shielding effect is studied under the joint influence of static magnetic field and alternating magnetic field. The experimental results show that for the proposed electromagnetic shielding room, indoor static magnetic fieldB≤ 200nT,50Hz AC magnetic interference<0.10μT,greater than 100kHz AC magnetic shielding factor S≥1000,which meets the practical requirements of the magnetic sensor system. This work can provide a necessary theoretical basis for the shielding effect evaluation of shielding room.关键词
