Yuav ua li cas txiav txim siab seb lub hnab los tiv thaiv kev tiv thaiv zoo li qub tau ua tsis tiav?
Cov hnab thaiv kev tiv thaiv zoo li qub yog siv rau kev ntim khoom sab nraud ntawm lub rooj sib txig, hluav taws xob qhov chaw thiab cov khoom siv hluav taws xob tiv thaiv hluav taws xob zoo li qub. Nws tuaj yeem tiv thaiv electrostatic rhiab Cheebtsam ntau tshaj plaws los ntawm cov peev xwm ntawm electrostatic. Lawv qhov tshwj xeeb Faraday tawb tsim hom" qhov induction npog" cov nyhuv, ntxiv rau daim ntaub thaiv thiab tiv thaiv zoo li qub cov ntsiab lus ntawm lub hnab.
Tab sis txhua yam muaj nws tus kheej tshwj xeeb. Piv txwv, lub hnab los tiv thaiv zoo li qub yuav ua swb. Koj puas paub yuav ua li cas thiaj li txiav txim siab tias lub hnab tiv thaiv kev tiv thaiv zoo li qub tau ua tsis tiav?
Hauv MIL-B-81705C daim ntawv tus qauv, yog tias ib qho ntawm cov xwm txheej hauv qab no tau ntsib, nws tuaj yeem raug suav tias yog qhov tsis raug:
1. Yog tias qhov tshwm sim txheej txheej nthuav dav hauv Ntu 4. 8. 4. 1 tshwm.
2. Attenuation tus nqi ntawm electrostatic kev tso tawm ntau dua li ntawm 2 vib nas this.
3. Attenuation ntawm electromagnetic cuam tshuam tsawg dua li 10 dB.
4. Muaj qhov me me hauv lub hnab thiab lub taub loj dua 2 hli.
5. Cov xwm txheej ntawm electrostatic tawm hauv qab 30 kV tsis tuaj yeem tiv thaiv.
6. Qhov chaw tiv thaiv ib puag ncig thaj tsam sab hauv thiab sab nraud yog ntau dua ntawm 10 ^ 12, thiab sab hauv tsis kam rau thaj chaw ib thaj tsam tsawg dua ntawm 10 ^ 5.
Hauv cov ntawv luv luv, vim yog qhov tshwm sim Faraday, yog tias muaj cov khoom plig lossis lub qhov me me hauv lub hnab los tiv thaiv zoo li qub, nws zoo dua rau qhov muab pov tseg thiab tsis txhob ua kom puas rau sab hauv vim cov nqi ntawm lub hnab.
