DC cable, DC cable yog ib hom neeg xyuas pib tshwj xeeb uas siv los xa ncaj qha tam sim no. Nws yog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob, lub zog tshiab thiab kev lag luam tshwj xeeb los muab lub zog rau cov khoom siv uas yuav tsum tau muaj qhov ruaj khov voltage thiab tam sim no.
DC thiab AC yog ob hom kev siv hluav taws xob. Lawv sib txawv heev nyob rau hauv ntau yam:
1, Cov yam ntxwv tseem ceeb thiab txoj hauv kev ua haujlwm
Cov kev taw qhia tam sim no ntawm cov hluav taws xob ncaj qha tseem ruaj khov, thiab qhov hluav taws xob yog qhov ruaj khov, thiab yuav tsis hloov nrog lub sijhawm. Cov kev taw qhia thiab qhov loj ntawm alternating tam sim no yuav hloov raws sij hawm, thiab nws yog feem ntau kis nyob rau hauv daim ntawv ntawm sine yoj.
Hauv kev siv tswv yim, qhov hluav taws xob AC tuaj yeem yooj yim nce thiab txo qis los ntawm kev hloov pauv, uas yog qhov tsim nyog rau qhov ntev - nrug thiab muaj zog sib kis tau zoo xws li State Grid. DC fais fab tuag muaj tsawg dua thaum kis tau tus mob, thiab feem ntau yog siv rau cov khoom siv thiab cov xwm txheej uas yuav tsum tau muaj zog txaus ruaj khov thiab nyob deb.
2.Daim ntawv thov scenarios
Daim ntawv thov ntawm DC cable / fais fab mov: feem ntau yog siv rau cov khoom siv uas yuav tsum tau ruaj khov DC fais fab mov. Feem ntau pom hauv:
Them lossis fais fab mov rau cov khoom siv hluav taws xob xws li xov tooj ntawm tes, laptops, routers, LED teeb, thiab lwm yam.
Lub zog tshiab: Cov hluav taws xob tsim los ntawm lub hnub ci photovoltaic yog qhov ncaj qha tam sim no, uas yuav tsum muaj DC cables rau kev sib kis.
Lwm qhov chaw: hluav taws xob tsheb them nyiaj (DC them ceev), cov chaw zov me nyuam, kev sib txuas lus, thiab lwm yam.
Daim ntawv thov ntawm AC cable / fais fab mov: feem ntau yog siv rau kev faib hluav taws xob thiab tsav tsheb.
Cov khoom siv hluav taws xob hauv tsev thiab kev lag luam: Cov phab ntsa uas peb siv hauv peb lub neej niaj hnub muab AC lub zog, uas yog siv rau cov tub yees, cua txias, teeb pom kev zoo, thiab lub cev muaj zog.
Kev xa hluav taws xob: Daim phiaj hluav taws xob thauj hluav taws xob los ntawm cov chaw tsim hluav taws xob mus rau ntau txhiab tsev neeg, feem ntau yog nyob ntawm kev hloov tam sim no.
3, Cable tsim thiab qauv sib txawv
Vim muaj cov yam ntxwv sib txawv tam sim no, DC cable thiab AC cable kuj sib txawv hauv kev tsim:
Rwb thaiv tsev yuav tsum tau: AC cable yuav tsim alternating magnetic teb thiab daim tawv nqaij nyhuv vim alternating tam sim no, yog li nws yuav tsum tau ntau dua kev ua tau zoo ntawm nws cov rwb thaiv tsev thiab shielding txheej los txo lub zog poob thiab electromagnetic cuam tshuam. Kev faib hluav taws xob hauv hluav taws xob thiab kev poob ntawm DC cable yog qhov sib txawv, yog li cov kev xav tau ntawm rwb thaiv tsev yog qhov tseem ceeb, thiab lub sij hawm ntev tiv taus hluav taws xob ruaj khov yog qhov tseem ceeb dua.
Polarity: DC cables muaj cov ncej zoo thiab tsis zoo. Thaum AC cable tsis muaj polarity, nws yuav tsum paub qhov txawv ntawm cov hlau nyob, xoom xaim thiab hauv av xaim.
Hauv cov ntsiab lus, DC cable yog qhov sib kis ntawm DC lub zog, thiab nws cov yam ntxwv tseem ceeb yog muab kev ruaj khov thiab kev taw qhia tsis sib xws. Qhov tseem ceeb sib txawv ntawm nws thiab AC (alternating tam sim no) yog qhov kev taw qhia ntawm tam sim no thiab seb nws hloov nrog lub sij hawm, uas ua rau muaj kev sib txawv ntawm kev sib kis tau zoo, muaj feem xyuam rau cov xwm txheej thiab cov qauv siv cable. Txawm siv DC lossis AC yog nyob ntawm cov khoom siv tshwj xeeb thiab cov xwm txheej thov.
