電磁屏蔽室指標的確定

2021年03月16日 |閱讀次數：512

一、對于防護性電磁屏蔽室，應根據以下原則確定屏蔽指標：

1.應根據實(shí)際測量值設計干擾場(chǎng)中外部電磁波的強度。當沒(méi)有測量數據時(shí)，理論計算值加上10dB的余量可以用作環(huán)境干擾場(chǎng)強水平的值。該值與電磁屏蔽室內工作區域中的允許干擾電平（dB）之差用作屏蔽有效性指標的要求。

2.電磁屏蔽室的工作頻率范圍應根據需要保護的頻帶來(lái)確定，并應考慮由多次諧波等因素引起的頻帶擴大。

電磁屏蔽室指標的確定

二、根據本規范要求建立的電磁屏蔽室，應在滿(mǎn)足其指標要求的基礎上，根據工程的實(shí)際情況進(jìn)行適當調整，但不得低于設備的要求。

三、用于安全保密的電磁屏蔽室，防止信號泄漏，屏蔽效果應符合保密規定的要求。
