Abubuwan lantarki na igiyoyin hotovoltaic

1. DC juriya

Juriya na DC na cibiyar gudanarwa na gamawana USB photovoltaica 20 ℃ bai fi 5.09Ω/km ba.

2. Gwajin wutar lantarki na nutsewar ruwa

Kebul ɗin da aka gama (20m) yana nutsewa cikin (20± 5) ℃ ruwa don 1h sannan kuma an yi gwajin ƙarfin lantarki na 5min (AC 6.5kV ko DC 15kV) ba tare da lalacewa ba.

3. Dogon wutar lantarki na DC

Samfurin yana da tsayi 5m kuma an sanya shi a cikin ruwa mai narkewa wanda ke dauke da 3% sodium chloride (NaCl) a (85 ± 2) ℃ don (240 ± 2) h, tare da duka iyakar da aka fallasa zuwa saman ruwa don 30cm. Ana amfani da wutar lantarki na DC na 0.9kV tsakanin tsakiya da ruwa (an haɗa ginshiƙan gudanarwa zuwa madaidaicin sanda kuma an haɗa ruwan zuwa sandar mara kyau). Bayan fitar da samfurin, ana yin gwajin ƙarfin lantarki na nutsewar ruwa, ƙarfin gwajin shine AC 1kV, kuma ba a buƙatar rushewa.

4. Juriya na rufi

Juriya na rufi na kebul na photovoltaic da aka gama a 20 ° C ba zai zama ƙasa da 1014Ω · cm ba,

Juriya na kebul na ƙãre a 90 ° C ba zai zama ƙasa da 1011Ω · cm ba.

5. juriya na sheath

Juriya na saman kumfa na USB da aka gama ba zai zama ƙasa da 109Ω ba.
