Yuav Ua Li Cas PV Array DC Isolator Hloov Tiv Thaiv Cov Txheej Txheem Photovoltaic?

       PV array DC isolator hloov, raws li lub npe qhia, yog qhov hloov pauv uas cais DC.Nws feem ntau yog siv nyob rau hauv photovoltaic fais fab chaw nres tsheb systems, thiab yog siv nruab nrab ntawm high-voltage DC photovoltaic arrays thiab daim phiaj-connected inverters los txiav tawm arcs generated los ntawm DC fais fab tuag, tsis txhob muaj xwm txheej txaus ntshai, thiab xyuas kom meej kev ruaj ntseg.Lawv nyob ze ntawm lub inverter thiab xav tau ib txoj kev ntawm manually cais tag nrho PV array thaum lub sij hawm installation los yog tej yam kev kho tom ntej.

Dab tsi yog Kev Tiv Thaiv Kev Ua Haujlwm ntawm PV Array DC Isolator Hloov?

(1) Thaum txhim kho lub tshuab hluav taws xob photovoltaic, tus installer feem ntau tig tawm DC hloov ua ntej kom cais cov tswv yim ntawm lub hnub ci vaj huam sib luag los ntawm inverter.Thaum lub sij hawm txuas thiab ntsaws ntawm DC terminals, DC lub hwj chim tsis txuas nrog DC sab ntawm lub inverter los tiv thaiv tus kheej hluav taws xob thiab kev puas tsuaj rau lub inverter thiab cov khoom siv rov qab.Yog li ntawd, thaum txhim kho lub system, peb xav tau ib tug PV array dc cais cais lub zog DC ntawm lub inverter thiab lub roj teeb vaj huam sib luag.

(2) Hauv qhov chaw nres tsheb fais fab photovoltaic, lub inverter yog "core center".Txhawm rau kom muaj lub sijhawm tsim hluav taws xob txaus, lub inverter tsis muaj lub pob pib nres.Tsuav yog muaj teeb pom kev zoo (txawm tias huab cua los nag), lub hnub ci vaj huam sib luag tuaj yeem tsim hluav taws xob thiab lub inverter tuaj yeem ua haujlwm tau.Txawm li cas los xij, qhov no kuj ua rau muaj teeb meem.Thaum hloov lossis kho lub inverter, txawm hais tias sab AC tau raug txiav tawm los ntawm kev teeb tsa AC Circuit Court breaker, DC sab ib txwm muaj zog.Nyob rau hauv rooj plaub no, yog tias lub inverter tsis muaj lub hnub ci array dc isolator hloov mus cais lub zog DC ntawm cov panels, nws yooj yim ua rau hluav taws xob poob siab thiab cov khoom puas.

(3) Tam sim no, feem ntau ntawm cov inverters nyob rau hauv kev ua lag luam yog ntawm TL series, uas yog, tsis muaj hluav taws xob cais nyob rau hauv, thiab muaj peev xwm rov qab ntws los ntawm AC sab mus rau DC sab.Thaum lub sijhawm tu, yog tias qhov hloov pauv AC thiab DC hloov pauv lub cev sib cais, nws tuaj yeem tiv thaiv kom nyab xeeb dua.

Ntau hom kev teeb tsa

Muaj 5 hom kev teeb tsa: Ib lub qhov mounting hom, vaj huam sib luag mounting hom, Rail mounting hom, Qhov rooj xauv mounting hom, thiab sab nrauv mounting hom.

Nta ntawm Slocable PV Array DC Isolators:
