Detailed Description

The principle of the utility model lies in that the electrified magnetic shielding is arranged in a certain area of the space for weakening the measure of the field intensity caused by some sources. In most cases, the shield can be made of metal such as copper, aluminum, steel, etc., but for constant and very low frequency magnetic fields, materials such as ferrite can also be used as the shield.

The utility model discloses a: the device comprises a shell 1, ferrite 2, wave-absorbing cotton 3, an illumination power supply 4, a box door 6 and an observation window 7.

The present invention will be further explained with reference to the drawings and examples.

Example 1: as shown in attached figure 1, a shell 1 of the box body is compounded with ferrite 2 and wave-absorbing cotton 3, a lighting power supply 4 is arranged in the box body, and a box door 6 and an observation window 7 are arranged on the outer wall of at least one side of the box body.

In the above, the power filter 5 is installed inside the box body, and the power filter 5 is connected to the lighting power source 4.

In the foregoing, the handle 8 is mounted on the top of the box body.

In the foregoing, the fixing frame 9 is installed inside the box body.

In the foregoing, the indicator light 10 is mounted on the outer wall of the box body, and the indicator light 10 is connected with the lighting power supply 4.

In the foregoing, the detection terminal 11 is mounted on the outer wall of the box body, and the detection terminal 11 is connected to the inside of the box body.

In the foregoing, the bottom of the box body is provided with the support legs.

In the embodiment of the present invention, the ferrite 2 is a metal oxide having ferrimagnetism. In terms of electrical properties, ferrites have a much higher resistivity than elemental metal or alloy magnetic materials, and also have higher dielectric properties. The magnetic properties of ferrites are also characterized by a high permeability at high frequencies. Therefore, ferrite has become a non-metallic magnetic material with wide application in the high-frequency weak-current field. Because the magnetic energy stored in the unit volume of the ferrite is low, the saturation magnetic induction intensity (Bs) is also low and is only 1/3-1/5 of that of pure iron, the application of the ferrite in the fields of low frequency strong electricity and high power requiring high magnetic energy density is limited.
