The influence of magnetic fields is significant, and there are some places where magnetic fields need to be isolated. Therefore, shielding rooms or equipment will be built, such as shielding test halls, which are also important. In order to fully utilize their functions, the design of shielding test halls is very meticulous. When designing the shielding test hall, there are corresponding principles that need to be followed.
1. The function of the shielding test hall is to perform shielding, so there are corresponding shielding standards. The general standards are: the shielding efficiency of the shielding test hall for near field personnel protection is 102 105, and the shielding efficiency of the shielding test hall for industrial interference protection is 105 108.
2. The size and location of the shielding test hall should be determined based on the actual situation, such as the power, output form, operating conditions, and on-site environment of the RF equipment. Generally, the distance between the shielding test hall and the RF equipment should not be less than 2 to 3 meters, and the distance should be uniform and equal.
3. The power lines in the shielding test hall should be designed reasonably. As the power lines or communication signal lines are also conductors, they may carry electromagnetic signals and cause interference. Therefore, corresponding filters should be installed to remove them.
4. The shielding test hall should be equipped with corresponding ventilation, entrances, and lighting facilities, but electromagnetic leakage should be minimized to the greatest extent; The shielding test hall should have good corrosion resistance, sufficient mechanical strength, hexagonal structure, and good electrical connectivity between various shielding components.
In summary, the design principles of the shielding test hall are quite important. The shielding test hall is playing an increasingly important role in today's use, and we believe that after improving the overall performance, we will also leverage its advantages. The shielding effectiveness varies depending on the purpose. So this also needs to be considered when designing. Overall, the price of the shielding test hall is quite expensive, so more consideration should be given when designing it.
