The working principle of electromagnetic shielding cabinet

Author:admin   AddTime:2021-05-09

Earlier, we gave you a brief introduction to electromagnetic shielding cabinets, and a simple understanding of electromagnetic shielding cabinets. So what I want to talk about here is the working principle of electromagnetic shielding cabinets. Here is an introduction for everyone:

The electromagnetic shielding cabinet is to stop the non-metallic isolation between the two time sea areas to control the induction and radiation of the magnetic field, electric field and radio waves from one degree sea area to another degree sea area. In detail, the shielded cabinet body is used to break out the elements, passages, couplings, wires, or the entire system of disturbance sources to prevent the disturbance electromagnetic field from dispersing, and the shielded cabinet body to absorb the passages, facilities or systems to break out and prevent them Subject to external electromagnetic field response.

The editor below introduces the working principle of electromagnetic shielding cabinet:



(1) When the frequency of disturbing the electromagnetic field is high, the vortex generated in the non-metallic material with low resistivity is used to form a counteracting effect on the external electromagnetic wave, so as to achieve the effect of shielding the cabinet.

(2) When the frequency of disturbing radio waves is low, materials with high magnetic permeability should be adopted, so that the magnetic line of force restricts the shielding cabinet from the outside and prevents the time to spread to the shielding cabinet.

(3) In some places, if an excellent shielding cabinet effect is required for both high-frequency and broadcast electromagnetic fields, the same non-metallic materials are often used to form a multi-layer shielding cabinet body.

The working principle of the electromagnetic shielding cabinet is the above we have introduced to you, so that we have a new understanding of why the electromagnetic shielding cabinet can be shielded.
