Kev tiv thaiv muaj nuj nqi ntawm AC fais fab faib txee
Lub AC fais fab faib txee yuav tsum muaj ntau yam kev tiv thaiv kab mob. Thaum qhov kev tiv thaiv tshwm sim, tus neeg siv tuaj yeem daws nws raws li qhov xwm txheej, tshem tawm qhov txhaum, thiab rov qab kho lub zog.
(1) Tso zis ntau dhau thiab tiv thaiv luv luv
Thaum muaj qhov luv luv -circuit lossis dhau- kev ua haujlwm tsis zoo nyob rau hauv qhov tso zis hluav taws xob, cov khoom siv hluav taws xob sib txuas yuav txiav tawm thiab txiav tawm yim qhov tawm. Thaum muaj xwm txheej hnyav dua, lub fuse yuav txawm tshuab; nyob rau lub sijhawm no, qhov ua rau yuav tsum raug txheeb xyuas ua ntej, qhov txhaum yuav tsum raug tshem tawm, thiab tom qab ntawd cov khoom thauj yuav tsum tau txuas nrog.
(2) Cov tswv yim nyob rau hauv -voltage tiv thaiv
Thaum cov input voltage ntawm lub kaw lus poob mus rau 70 feem pua -35 feem pua ntawm cov ntsuas hluav taws xob ntawm lub hwj huam mov, lub tswv yim tswj kev hloov pauv yuav txiav tawm mus thiab tsuas yog txiav tawm lub hwj chim; Thaum qhov hluav taws xob input ntawm lub kaw lus qis dua 35 feem pua ntawm qhov ntsuas hluav taws xob, qhov hloov hluav taws xob hluav taws xob tsis tuaj yeem raug kaw rau kev xa hluav taws xob. Nyob rau lub sijhawm no, vim li cas thiaj yuav tsum tau kuaj xyuas kom nce qhov input voltage ntawm lub plab, thiab tom qab ntawd rov qab kho lub zog.
Thaum lub AC fais fab faib txee yog siv los ntawm inverter, nws muaj kev ua haujlwm ntawm cov roj teeb undervoltage tiv thaiv. Thaum lub roj teeb tawm mus txog qhov tob, tus maub los xa lub teeb liab los txiav tawm lub nra, tswj lub hwj chim faib txee, thiab lub load relay ntawm P ua rau txiav tawm qhov ntxiv load. Thaum lub hwj chim rov qab los, tsuas yog nias lub pob.
(3) Input interlock tiv thaiv
Kev tiv thaiv kev ruaj ntseg tshaj plaws ntawm AC fais fab faib txee ntawm qhov chaw nres tsheb fais fab photovoltaic yog ob txoj kev tiv thaiv kev tiv thaiv ntawm cov relay thiab Circuit Court breaker hloov ntawm lub tso zis tso quav: qhov cuam tshuam kev tiv thaiv muaj nuj nqi yog tias thaum lub inverter input los yog diesel generator teeb input muaj tsuas yog ib qho. channel nrog 41, lwm yam Tag nrho txoj kev ntawm relay yuav raug kaw, uas yog, lub khawm ua haujlwm hluav taws kub. Nyob rau hauv lwm yam lus, lub Circuit Court breaker hloov interlock tiv thaiv tso cai tsuas yog ib tug hloov mus kaw thiab energized. Lub sijhawm no, yog tias lwm qhov hloov pauv tseem raug kaw, ob lub voj voog yuav raug txiav tawm tib lub sijhawm.
Muaj ntau Fuses, cov khoom lag luam npog tag nrho cov cheeb tsam ntawm lub zog tshiab tsheb (Pack, PDU, BDU, Hluav taws xob tswj, Lub cev muaj zog, MSD, Tsis tshua muaj hluav taws xob thaiv kab hluav taws xob), Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, Photovoltaic PV Hnub ci hlws ris lub thawv, photovoltaic inverter, UPS fais fab mov, 5G Kev sib txuas lus fais fab mov, BS UK plug, Hluav taws xob cov khoom siv hauv tsev tswj vaj huam sib luag, teeb pom kev zoo tsav fais fab mov thiab lwm yam.
