屏蔽機房的功能分類

详情描述：

機房沒有做屏蔽情況下，電子設備容易強電磁干擾源的影響，導致設備無法工作或出現異常。
屏蔽機房的功能分類：
1. 靜電屏蔽：將金屬屏蔽體接地，外側的正電荷將流入大地，便不會有電場存在。
2. 交變電場屏蔽：設法使金屬屏蔽體良好接地，就能使交變電場對敏感電路的耦合干擾電壓變小。
3. 
交變磁場屏蔽：交變磁場屏蔽分高頻和低頻，低頻利用高磁導率的材料構成低磁阻通路，使大部分磁場被集中在屏蔽體內;高頻利用高電導率的材料產生渦流的反向磁場抵消干擾磁場。
4. 交變電磁場：採用電導率高的材料做屏蔽體並接地，並利用屏蔽體在高頻磁場的作用下產生反方向的渦流磁場與原磁場抵消，削弱高頻磁場的干擾。

Functional classification of the shielding room:
1. Electrostatic Shielding: Ground the metal shield and the positive charge 
on the outside will flow into the ground, so there will be no electric 
field.
2. Alternating electric field shielding: Try to make the metal shield well 
grounded, so that the coupling interference voltage of the alternating electric 
field to the sensitive circuit becomes smaller.
3. Alternating magnetic field shielding: alternating magnetic field shielding 
is divided into high frequency and low frequency. Low frequency uses high 
magnetic permeability material to form low magnetic reluctance path, so that 
most of the magnetic field is concentrated in the shielding body; high frequency 
is generated by high conductivity material. The reverse magnetic field of the 
eddy current cancels the disturbing magnetic field.
4. Alternating electromagnetic field: The material with high conductivity is 
used as the shielding body and grounded, and the eddy current magnetic field in 
the opposite direction is generated by the shielding body under the action of 
the high-frequency magnetic field to cancel the original magnetic field, which 
weakens the interference of the high-frequency magnetic field.
