Raws li qhov yuav tsum tau ua ntawm tus qauv IEC61730-2 [2] : Photovoltaic modules yuav tsum muaj peev xwm tiv taus rov qab tam sim no overload. Cov kev cai ntawm kev ntsuas rov qab overcurrent yog raws li nram no: Rau pv modules nrog A siab tshaj plaws fuse tam sim no ntawm 15A, A 2-teev xeem ntawm 20.25A (1.35 zaug) yog yuav tsum tau, cov modules yuav tsum tsis txhob hlawv, muslin thiab nyias daim ntawv dawb nyob rau hauv kev sib cuag nrog cov modules yuav tsum tsis txhob hlawv lossis hlawv, thiab MST 17 xeem (kev ntsuas ntub dej tam sim no) yuav tsum ua tau raws li qhov yuav tsum tau ua raws li qhov kev sim thawj zaug.
Yog li, photovoltaic modules tau ntawv pov thawj raws li IEC61730-2 yuav tsum muaj peev xwm tiv taus 1.35 npaug ntawm qhov rov qab tam sim no 2h.
Raws li cov kev cai saum toj no, kev ntsuas yuav tsum tau ua los tiv thaiv DC tsheb npav ntawm sab ntawm photovoltaic inverter (lossis DC lub thawv tsheb npav) los ntawm kev txhim kho kev nyab xeeb thiab txuas ntxiv lub neej ntawm photovoltaic modules. Yog li ntawd, IEC60269-6 [3] tus qauv rau photovoltaic fuse (15A) cov kev cai:" yuav tsum tau fuse tam sim no ntawm 21.75A (1.45 zaug) hauv 1 teev". Txawm li cas los xij, hauv UL2579 [4] tus qauv, nws yuav tsum tau fuse hauv 1 teev thaum qhov tam sim no yog 20.25A (1.35 zaug).
Raws li qhov rov qab muaj peev xwm tshaj qhov tam sim no ntawm cov khoom siv (IEC61730-2), UL tus qauv yuav tsum tsim nyog, thiab cov kev cai ntawm IEC 60269-6 tus qauv yuav raug kho dua. Rau fuses nrog ntsuas tam sim no tsawg dua 32A (xws li 32A), lawv yuav tsum tau fused hauv 1h thaum dhau 1.35 npaug ntawm qhov ntsuas tam sim no. Mainstream fuse manufacturers xws li Bussmann thiab Littelfuse, uas yog ceev los teb rau technology, kuj tau hloov kho cov khoom parameter yuav tsum tau rau tus tsim ntawm photovoltaic fuses.
Dissmann tau tsim thiab tshawb fawb, mob siab rau fuses rau cov tshuab photovoltaic uas muab kev tiv thaiv kev tiv thaiv, Matching Europe, America thiab Middle East kev lag luam. Tshwj xeeb fuses rau cov khoom photovoltaic: ua ke lub thawv; 10 * 38, 10 * 85, 14 * 51, 14 * 65 fuse; MEV fuse; BS88 fuse; HEV fuse; NH hom fuse. Nws tuaj yeem ua tiav feem ntau hauv lub zog tshiab& Kev xav tau lub zog tauj dua tshiab, zoo li lub tsheb hluav taws xob, chaw nres tsheb them nqi, roj teeb pob, 5G kev sib txuas lus, photovoltaic fuse, lub zog cia, lub thawv sib txuas fuse, hnyav kev lag luam hauv tsheb laij teb thiab lwm yam ...
Yog li ntawd, thaum lub fuse tam sim no tsis ntau tshaj qhov txwv ntawm qhov kev tiv thaiv tam sim no ntawm photovoltaic modules thiab lub sij hawm fuse tsis ntev tshaj li lub sij hawm rov qab tam sim no kam rau ntawm photovoltaic modules, lub fuse tuaj yeem tiv thaiv photovoltaic modules.
