IEC 60364-7-712: 2017

Kev teeb tsa hluav taws xob hluav taws xob tsawg - Tshooj 7-712: Yuav tsum muaj rau kev teeb tsa tshwj xeeb lossis chaw nyob - Hnub ci photovoltaic (PV) lub zog hluav taws xob

International Electrotechnical Commission (IEC) tau tso tawm IEC 60364-7-712: 2017 rau "kev tso hluav taws xob tsis tshua muaj hluav taws xob - Tshooj 7-712: qhov xav tau rau kev teeb tsa tshwj xeeb lossis chaw nyob - Hnub ci photovoltaic (PV) lub zog hluav taws xob".

Nqe lus piav qhia: "IEC 60364-7-712: 2017 siv rau kev teeb tsa hluav taws xob ntawm PV systems npaj los muab tag nrho lossis ib feem ntawm kev teeb tsa. Cov cuab yeej ntawm kev teeb tsa PV, ib yam li lwm yam khoom siv, tau ua nrog tsuas yog kom nws xaiv thiab thov hauv kev teeb tsa muaj kev txhawj xeeb. Tsab ntawv tshiab no suav nrog kev hloov kho tseem ceeb thiab txuas ntxiv, suav nrog kev paub dhau los hauv kev tsim kho thiab kev ua haujlwm ntawm PV kev teeb tsa, thiab kev tsim kho hauv tshuab, txij li thawj tsab ntawm tus qauv no tau luam tawm. "

Tau:

Qhov no ntawm IEC 60364 siv rau kev teeb tsa hluav taws xob ntawm PV systems npaj los muab tag nrho lossis ib feem ntawm kev teeb tsa.

Cov khoom siv ntawm lub PV installation, zoo ib yam li lwm yam khoom siv, tau hais txog tsuas yog kom deb li deb nws xaiv thiab daim ntawv thov hauv lub installation muaj kev txhawj xeeb.

Ib qho PV installation pib los ntawm PV module lossis teeb tsa ntawm PV modules txuas nrog hauv nrog lawv cov kab hluav taws xob, muab los ntawm PV module chaw tsim tshuaj paus, mus txog tus neeg siv teeb tsa lossis cov khoom siv hluav taws xob (taw tes ntawm kev sib koom ua ke).

Yuav tsum muaj cov ntaub ntawv no siv rau

• PV nruab nrog tsis txuas rau cov kab ke xa hluav taws xob rau pej xeem,
• PV nruab nrog tso rau hauv cov kab ke rau kev faib hluav taws xob rau pej xeem,
• PV kev teeb tsa ua lwm txoj hauv kev rau cov hluav taws xob faib rau cov pej xeem,
• tsim nyog kev sib txuas ntawm cov saum toj no. Cov ntaub ntawv no tsis hais txog cov teeb meem tshwj xeeb kev teeb tsa rau cov roj teeb lossis lwm txoj kev cia zog.

CEEB TOOM 1 Cov kev cai ntxiv rau kev txhim kho PV nrog cov roj teeb cia muaj peev xwm nyob rau sab DC tau tab tom txiav txim.

NCO TSEG 2 daim ntawv no npog cov kev tiv thaiv cov cai ntawm PV arrays uas tsim tawm los ntawm kev siv roj teeb hauv PV nruab.

Rau cov tshuab siv DC-DC hloov, yuav tsum ntxiv txog qhov ntsuas hluav taws xob thiab kev ntaus nqi tam sim no, hloov mus, thiab cov khoom siv tiv thaiv tuaj yeem siv tau. Cov tseev kom muaj nyob hauv kev txiav txim siab.

Lub hom phiaj ntawm cov ntawv no yog los daws cov qauv kev nyab xeeb ntawm kev tsim qauv uas tshwm sim los ntawm cov yam ntxwv tshwj xeeb ntawm kev sib txuas PV. DC systems, thiab PV arrays tshwj xeeb, ua rau muaj qee qhov phom sij ntxiv rau cov uas tau txais los ntawm cov pa hluav taws xob tshwj xeeb, suav nrog kev muaj peev xwm tsim thiab txhawb cov hluav taws xob hluav taws xob nrog cov khoom hluav taws xob uas tsis loj dua li ib txwm ua haujlwm tam sim no.

Nyob rau hauv daim phiaj sib txuas nrog PV kev teeb tsa kev nyab xeeb cov cai ntawm daim ntawv no yog, txawm li cas los xij, qhov tseem ceeb nyob ntawm PCE cuam tshuam nrog PV arrays ua tau raws li cov cai ntawm IEC 62109-1 thiab IEC 62109-2.
