Ukuxhumeka kwe-Equipotential kumasistimu we-photovoltaic Amadivayisi aphansi kanye nama-conductor avikelayo kumasistimu we-photovoltaic azohambisana ne-IEC60364-7-712:2017, ehlinzeka ngolwazi olwengeziwe. Ubuncane bendawo ephambanayo yomugqa webhondi ye-equipotential kufanele ihlangabezane nezidingo ze-IEC60364-5-54, IEC61643-12 kanye ne-GB/T21714.3-2015. Uma ama-equipotential bonding strips asetshenziswa njengamakhondatha aphansi, indawo yawo encane ewela ingxenye kufanele kube izintambo zethusi ezingu-50mm, noma amakhondatha amandla aphethe amandla alinganayo. Uma i-equipotential bonding strip kulindeleke ukuthi ibambe umbani, indawo yayo encane enqamula izingxenye kufanele kube iphinikhodi engu-16mm, noma umthamo wamanje olinganayo. umqhubi. 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 umqhubi. Ubuncane bendawo ye-cross-sectional ye-conductor exhumayo exhuma izingxenye ze-conductive ku-equipotential bonding strip izoba yi-6mm intambo yethusi, noma umthamo ofanayo wokuthwala wamanje. umqhubi. Uma lungekho uhlelo lwe-photovoltaic oluxhunywe ohlelweni lokuvikela umbani, indawo encane enqamula ingxenye yamakhondaktha axhumayo axhunywe emigqeni ehlukene yokuxhuma kanye namakhondaktha axhunywe ohlelweni oluphansi kufanele kube intambo yethusi engu-6mm, noma efanayo yamanje- ethwele umthamo conductors. Qaphela: Izidingo eziyisisekelo ze-cross-section zamakhondatha ziyahlukahluka kwamanye amazwe. Lo mehluko uchazwe ku-GB/T 217143-2015. Ingxenye ye-LPS okulindeleke ukuthi igeleze ingxenye yombani kufanele ihambisane ne-IEC 62561 (zonke izingxenye). Lapho uhlelo lwe-photovoltaic luvikelwe uhlelo lokuvikela umbani, ibanga elincane lokuhlukanisa eliphephile kufanele ligcinwe phakathi kwesistimu yokuvikela umbani kanye nezakhiwo zensimbi zesistimu ye-photovoltaic ukuvimbela ingxenye yamanje yombani ukuba ingagelezi kulezi zakhiwo. Indawo encane ehlukanisayo yawo wonke amakhondaktha we-equipotential bonding ngu-6mm, ngaphandle kwamakhondaktha aphansi we-class I surge bavikeli kukhabhinethi yokusabalalisa enkulu. Uma amamojula we-photovoltaic evikelwe uhlelo lokuvikela umbani kodwa ibanga lokuhlukanisa eliphephile alikwazi ukugcinwa phakathi kokubili, ukuxhumana okuqondile kufanele kwengezwe phakathi kwesistimu yokuvikela umbani wangaphandle kanye nesakhiwo sensimbi se-photovoltaic array. Lokhu kuxhumana kufanele kukwazi ukumelana nombani wamanje. Indawo ephansi ye-cross-sectional ye-equipotential bonding conductor izohlangabezana nezidingo ze-IEC60364-5-541EC61643-12 kanye ne-GB/T217143-2015. Ubuncane bendawo ephambanayo yawo wonke amakhondaktha we-equipotential bonding izoba ngu-16mm, ngaphandle kwamabhande e-equipotential bonding ukuze agxilise inverter.
