Dab tsi yog qhov txawv ntawm AC thiab DC lub thawv sib txuas?

AC (Alternating Current) thiab DC (Direct Current)cov thawv sib xyawua haujlwm sib txawv hauv cov tshuab hluav taws xob, tshwj xeeb hauv cov tshuab hluav taws xob txuas ntxiv xws li hnub ci photovoltaic (PV) kev teeb tsa.

AC combiner lub thawv yog siv los ua ke ntau yam AC circuits los ntawm hnub ci inverters lossis lwm qhov chaw AC. Cov circuits no muaj alternating tam sim no, uas yog hom tam sim no feem ntau siv nyob rau hauv tsev thiab lag luam hluav taws xob systems.

DC Combiner Box:DC Combiner Box, ntawm qhov tod tes, yog siv los ua ke ntau txoj hlua DC lossis arrays ntawm lub hnub ci vaj huam sib luag ua ntej lawv txuas nrog lub hnub ci inverter. Cov hlua los yog cov arrays no tsim cov tam sim no ncaj qha, uas yog hom tam sim no tsim los ntawm cov hnub ci vaj huam sib luag.

AC cov thawv sib txuas feem ntau ua rau qis qis qis vim tias lawv cuam tshuam nrog cov zis los ntawm inverters, uas hloov DC rau AC ntawm qhov hluav taws xob tsim nyog rau kev sib txuas kab sib txuas (xws li 120V, 240V, 480V).

DC Combiner Box: DC cov thawv sib txuas yuav tsum tswj cov qib hluav taws xob ntau dua vim tias lawv tau cuam tshuam nrog cov khoom siv hluav taws xob DC los ntawm cov hnub ci vaj huam sib luag, uas muaj peev xwm ntau ntawm ntau pua volts mus rau ntau dua 1,000 volts nyob ntawm qhov kev teeb tsa thiab qhov loj ntawm lub system.

Cheebtsam hauv AC cov thawv sib txuas, xws li cov khoom siv hluav taws xob lossis cov fuses, feem ntau yog ntsuas rau AC daim ntawv thov thiab tej zaum yuav muaj qhov sib txawv tshwj xeeb piv rau cov siv hauv DC cov thawv sib txuas.

DC Combiner Box: Cheebtsam hauv DC cov thawv sib txuas, suav nrog fuses, Circuit Court breakers, thiab surge protectors, yuav tsum tau tsim tshwj xeeb thiab ntsuas rau DC daim ntawv thov vim muaj qhov sib txawv ntawm DC hluav taws xob.

Kev txiav txim siab txog kev nyab xeeb:

Kev txiav txim siab txog kev nyab xeeb rau AC cov thawv sib txuas tsom rau kev tiv thaiv overcurrent thiab luv circuits, nrog rau kev muab kev sib cais thiab kev txiav tawm txhais tau tias raws li qhov xav tau los ntawm cov lej hluav taws xob.

Ntxiv nrog rau kev tiv thaiv overcurrent thiab luv luv Circuit Court, kev ntsuas kev nyab xeeb rau DC cov thawv sib txuas kuj suav nrog kev tiv thaiv arcing thiab rwb thaiv tsev tsis ua haujlwm vim muaj qhov sib txuam ntau dua.

Hauv cov ntsiab lus, AC thiabDC Combiner BoxSib txawv ntawm hom tam sim no lawv tuav, qib voltage, xaiv cov khoom siv, thiab kev xav txog kev nyab xeeb. Lawv ua lub luag haujlwm sib txawv hauv cov tshuab hluav taws xob tauj dua tshiab thiab yuav tsum tau xaiv thiab teeb tsa kom tsim nyog raws li cov cai tshwj xeeb ntawm qhov system.
