Vim li cas lub shielding txheej yuav tsum tau grounded?

Lub shielding txheej yog ib tug hlau nrog ib tug hlau braid plhaub tshwj xeeb uas siv los txo cov kev cuam tshuam ntawm sab nraud electromagnetic teb ntawm lub hwj chim mov los yog kev sib txuas lus kab. Qhov zoo ntawm cov hlau thaiv no tseem tiv thaiv lub voj voog ntawm hluav taws xob hluav taws xob hluav taws xob sab nraud.
Yog vim li cas rau grounding lub shielding txheej: Multi-point grounding txoj kev xws li nruab nrab grounding thiab ob-kawg grounding yog haum rau ob-insulated cais shielded cables. Cov txheej txheej sab nrauv induces ib tug tam sim no nyob rau hauv thiaj li yuav qhia tau ib tug muaj peev xwm sib txawv, li no generating magnetic flux uas txo qhov kev siv ntawm qhov chaw magnetic teb, li no Yeej yuav tshem tawm cov voltage induced yam tsis muaj cov ntaub thaiv npog sab nrauv. Cov ntaub thaiv npog sab hauv ntawm ob chav insulated thiab shielded cable yuav tsum tau grounded ntawm ib kawg. Raws li lub hauv paus ntsiab lus uas tsis muaj qhov sib txawv thiab tsis muaj kev cuam tshuam tam sim no, nws tuaj yeem siv rau kev siv tshuaj tiv thaiv zoo li qub.
