Kulumikizana kwa equipotential mu ma photovoltaic systems Zipangizo zoyatsira pansi ndi zotetezera zotetezera mu photovoltaic systems zidzatsatira IEC60364-7-712: 2017, yomwe imapereka zambiri. Chigawo chocheperako chamzere wolumikizana ndi equipotential chiyenera kukwaniritsa zofunikira za IEC60364-5-54, IEC61643-12 ndi GB/T21714.3-2015. Ngati ma equipotential bonding strips agwiritsidwa ntchito ngati ma conductor otsika, gawo lawo locheperako liyenera kukhala mawaya amkuwa a 50mm, kapena ma kondakitala onyamulira pakali pano. Ngati chingwe cholumikizira equipotential chikuyembekezeka kuchititsa mphezi, gawo lake locheperako liyenera kukhala waya wa pini wa 16mm, kapena mphamvu yofananira pano. kondakitala. 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 kondakitala. Chigawo chocheperako cholumikizira cholumikizira cholumikizira magawo olumikizirana ndi chingwe cholumikizira chizikhala cha waya wamkuwa wa 6mm, kapena mphamvu yonyamulira yofananira. kondakitala. Pakakhala kuti palibe photovoltaic system yolumikizidwa ndi chitetezo cha mphezi, gawo locheperako la ma conductor olumikizira omwe amalumikizidwa ndi zingwe zolumikizira zosiyanasiyana ndi ma conductor olumikizidwa ndi dongosolo lokhazikitsira pansi ayenera kukhala waya wamkuwa wa 6mm, kapena wofanana pakali pano- kunyamula capacity conductors. Zindikirani: Zofunikira zochepa pama kondakitala zimasiyana m'maiko ena. Kusiyana kumeneku kumafotokozedwa mu GB/T 217143-2015. Gawo la LPS lomwe likuyembekezeka kuyenda gawo la mphezi liyenera kutsatira IEC 62561 (mbali zonse). Pamene dongosolo la photovoltaic limatetezedwa ndi chitetezo cha mphezi, mtunda wocheperapo wolekanitsa wotetezeka uyenera kusungidwa pakati pa chitetezo cha mphezi ndi zida zachitsulo za photovoltaic system kuti zisawononge mbali ya mphezi yomwe ikudutsa muzinthuzi. Malo ocheperako opangira ma equipotential bonding conductors ndi 6mm, kupatula ma conductor apansi a kalasi I oteteza oteteza mu nduna yayikulu yogawa. Ngati ma modules a photovoltaic amatetezedwa ndi chitetezo cha mphezi koma mtunda wolekanitsa wotetezeka sungathe kusungidwa pakati pa ziwirizi, kugwirizana kwachindunji kuyenera kuwonjezeredwa pakati pa njira yotetezera mphezi yakunja ndi zitsulo zamtundu wa photovoltaic. Kulumikizana kumeneku kuyenera kupirira mphezi zina. Malo ocheperako opangira ma equipotential bonding akwaniritsa zofunikira za IEC60364-5-541EC61643-12 ndi GB/T217143-2015. Malo ocheperako opangira ma equipotential ma kondakitala onse azikhala 16mm, kupatula zingwe zomangira zolumikizirana kuti zikhazikitse inverter.
