Equipotential kev sib txuas hauv photovoltaic systems Cov khoom siv hauv av thiab cov khoom tiv thaiv hauv cov tshuab photovoltaic yuav tsum ua raws li IEC60364-7-712: 2017, uas muab cov ntaub ntawv ntxiv. Qhov tsawg kawg nkaus hla ntu ntawm cov hlua khi sib txuas yuav tsum ua raws li cov cai ntawm IEC60364-5-54, IEC61643-12 thiab GB / T21714.3-2015. Yog hais tias equipotential bonding strips yog siv los ua tus neeg xyuas pib, lawv qhov tsawg kawg nkaus ntu ntu yuav tsum yog cov xov tooj ntawm 50 hli, los yog sib npaug tam sim no cov khoom muaj peev xwm. Yog hais tias lub equipotential bonding sawb yuav tsum ua xob laim tam sim no, nws qhov tsawg kawg nkaus cross-sectional cheeb tsam yuav tsum yog 16 hli tus pin hlau, los yog sib npaug tam sim no muaj peev xwm. tus thawj coj. If the equipotential bonding strip is expected to conduct only induced lightning current, its minimum cross-sectional area shall be 6mm copper wire or equivalent current-carrying capacity tus thawj coj. Qhov tsawg kawg nkaus cross-sectional cheeb tsam ntawm kev sib txuas tus neeg xyuas pib txuas cov khoom siv hluav taws xob mus rau equipotential bonding sawb yuav tsum yog 6 hli tooj liab hlau, lossis sib npaug tam sim no nqa lub peev xwm. tus thawj coj. Thaum tsis muaj lub tshuab hluav taws xob photovoltaic txuas nrog kev tiv thaiv xob laim, qhov tsawg kawg nkaus ntawm qhov chaw sib txuas ntawm cov khoom sib txuas txuas nrog cov kab sib txuas sib txawv thiab cov conductors txuas nrog hauv av yuav tsum yog 6 hli tooj liab hlau, los yog sib npaug tam sim no- nqa peev xwm conductors. Lus Cim: Yam tsawg kawg nkaus qhov yuav tsum tau muaj rau cov neeg xyuas pib sib txawv hauv qee lub tebchaws. Cov kev sib txawv no tau piav qhia hauv GB / T 217143-2015. Ib qho LPS uas xav tias yuav ntws ib feem ntawm cov hluav taws xob tam sim no yuav tsum ua raws li IEC 62561 (txhua qhov chaw). Thaum lub kaw lus photovoltaic tiv thaiv los ntawm kev tiv thaiv xob laim, qhov tsawg kawg nkaus kev nyab xeeb kev sib cais yuav tsum tau khaws cia ntawm qhov kev tiv thaiv hluav taws xob thiab cov txheej txheem hlau ntawm photovoltaic system kom tiv thaiv ib feem ntawm xob laim tam sim no los ntawm cov qauv no. Qhov tsawg kawg nkaus cross-sectional cheeb tsam ntawm tag nrho cov equipotential bonding conductors yog 6 hli, tshwj tsis yog cov av conductors ntawm chav kawm I surge protectors nyob rau hauv lub ntsiab tis txee. Yog tias cov khoom siv hluav taws xob photovoltaic muaj kev tiv thaiv los ntawm kev tiv thaiv xob laim tab sis kev sib cais kev nyab xeeb tsis tuaj yeem tswj hwm ntawm ob, kev sib txuas ncaj qha yuav tsum tau ntxiv ntawm cov hluav taws xob tiv thaiv sab nraud thiab cov qauv hlau ntawm photovoltaic array. Qhov kev sib txuas no yuav tsum muaj peev xwm tiv taus qee qhov hluav taws xob tam sim no. Qhov tsawg kawg nkaus cross-sectional cheeb tsam ntawm equipotential bonding conductor yuav tsum tau raws li cov kev cai ntawm IEC60364-5-541EC61643-12 thiab GB/T217143-2015. Qhov tsawg kawg nkaus cross-sectional cheeb tsam ntawm tag nrho cov equipotential bonding conductors yuav tsum yog 16 hli, tshwj tsis yog rau equipotential bonding straps rau grounding lub inverter.
