Lub hauv paus ntsiab lus rau xaiv cov shielding hom rau tswj cables

(1) Hloov cov teeb liab, tuaj yeem tiv thaiv tag nrho cov ntaub thaiv npog;
(2) Rau qib siab analog teeb liab, nws raug nquahu kom siv tag nrho kev tiv thaiv ntawm cov tub ntxhais hlau, thiab yog tias tsim nyog, ib feem thaiv ntawm cov tub ntxhais hlau kuj tseem siv tau;
(3) Qib qis analog teeb liab lossis cov cim mem tes yuav tsum tau tiv thaiv nyias los ntawm cov tub ntxhais hlau, thiab yog tias tsim nyog, cov ntaub thaiv npog tag nrho uas muaj cov thaiv thaiv los ntawm cov tub ntxhais hlau kuj tseem siv tau.
Hais txog txoj hauv kev hauv av ntawm txheej thaiv, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
(1) Cov txheej thaiv tiv thaiv kab hluav taws xob rau lub teeb liab analog ntawm lub khoos phis tawj tswj hwm yuav tsum tau muab tso rau ntawm qhov chaw nruab nrab. Qhov laj thawj yog raws li qhov yuav tsum tau ua kom ntseeg tau qhov kev ua haujlwm ib txwm siv ntawm lub khoos phis tawj saib xyuas, vim tias txawm tias qhov cuam tshuam ntawm qhov tsuas yog li 1V tuaj yeem ua rau muaj kev txiav txim siab tsis raug. Concentrating ib tug grounding point yuav zam qhov tshwm sim ntawm grounding ncig;
(2) Tsuas yog cov txheej txheem tswj cable thaiv txheej ntawm lub khoos phis tawj saib xyuas tsuas yog tso cai rau hauv nruab nrab hauv av ntawm ib qho chaw, rau lwm qhov kev tswj hwm cable thaiv cov khaubncaws sab nraud povtseg, ob-point grounding yuav tsum tau siv thaum electromagnetic induction cuam tshuam tseem ceeb, thiab ib qho taw qhia. grounding yuav tsum tau siv thaum electrostatic induction cuam tshuam tseem ceeb;
(3) Cov ntaub thaiv npog sab hauv ntawm ob lub thaiv thaiv npog los yog cov ntaub thaiv npog tag nrho yuav tsum tau muab tso rau ntawm ib qho chaw, thaum cov txheej thaiv sab nrauv tuaj yeem raug grounded ntawm ob lub ntsiab lus;
(4) Thaum xaiv ob lub ntsiab lus hauv av, nws yuav tsum tau txiav txim siab tias txheej thaiv thaiv yuav tsis raug hlawv tawm hauv qhov kev txiav txim ntawm qhov tam sim no.
