Basic Knowledge Ntawm Hlau Thiab Cable

Cov hlau thiab cables feem ntau muab faib ua tsib pawg: cov xov hlau liab qab, cov xov hlau hluav taws xob, hluav taws xob cables, xov hlau thiab cables rau cov khoom siv hluav taws xob thiab kev sib txuas lus cables. Ntau hom xov hlau thiab cables muaj ntau lub ntsiab lus thiab kev ua haujlwm. Cia's ua tib zoo saib ntawm cov hom ntawm cov xov hlau thiab cables.

Liab qab hlau yog ib hom hlau uas tsis muaj pob khoom thaiv, uas yog siv rau sab nraum zoov nyiaj siv ua haujlwm.

Electromagnetic hlau yog hais txog cov hlau siv nyob rau hauv electromagnetic coil, uas yog tag nrho cov xov hlau electromagnetic. Electromagnetic hlau muaj cov kev xav tau siab rau cov txheej txheem xaim, thiab yuav tsum tau hloov mus rau qhov hnyav ib puag ncig xws li kev vibration muaj zog, centrifugation, kub kub, corrosion thiab lwm yam.

Fais fab cables yog siv los xa thiab faib hluav taws xob hluav taws xob. Cov qauv siv hluav taws xob yog tus cwj pwm hauv cov ntawv roj, roj hmab lossis yas yog qhwv rau ntawm tus neeg xyuas pib. Lub cable muaj kev tiv thaiv corrosion, muaj zog rwb thaiv tsev, tuaj yeem tiv taus hluav taws xob siab thiab tsis tshua muaj kev xav tau rau ib puag ncig kev pabcuam.

Hlau thiab cables rau cov khoom siv hluav taws xob feem ntau yog siv hauv lub neej txhua hnub. Lawv tsuas yog siv los sib sau cov khoom siv hluav taws xob thiab cov cuab yeej siv hluav taws xob thiab hloov hluav taws xob hluav taws xob.

Kev sib txuas lus cable feem ntau yog siv los xa TV, xov tooj, network thiab tshaj tawm xov xwm. Nws muaj cov yam ntxwv ntawm lub teeb liab loj muaj peev xwm thiab muaj zog tiv thaiv kev cuam tshuam.

Muaj peb hom cable tais: jumper tray, uas feem ntau yog siv rau cov kab loj loj xws li fais fab cables. Trough hom ncaj nraim los ntawm tus choj feem ntau yog siv rau kev sib txuas lus cables xws li kev sib txuas lus, kev sib txuas lus thiab kev tiv thaiv hluav taws, thiab tais hom ncaj nraim los ntawm tus choj yog siv rau cov fais fab cables thiab cov teeb liab, nrog rau ntau yam kev siv.

Cov khoom siv hluav taws xob uas xav tau rau kev tso kab hluav taws xob muaj xws li cable davhlau ya nyob twg hlws ris lub thawv, cable intermediate junction box, txuas yeeb nkab thiab davhlau ya nyob twg, steel phaj txuas zawj, cable choj, thiab lwm yam,

Thaum xaiv cov xov hlau thiab cables, feem ntau them sai sai rau cov teeb meem hauv qab no:

1. Qhov ntsuas hluav taws xob ntawm cov hlau yog 1.5 npaug siab dua qhov tseeb voltage.

2. Lub peev xwm nqa tam sim no ntawm tus neeg xyuas pib feem ntau ntau dua 1.5 npaug ntawm qhov tam sim no.

3. Thaum tso cov cables ntev, qhov kev poob qis yuav tsum raug xam raws li qhov ntev.

4. Tus neeg xyuas pib yuav tsum tau dais qhov voltage thiab tam sim no thaum lub cuab yeej tiv thaiv ua haujlwm.
