Mphamvu zamagetsi za zingwe za photovoltaic

1. DC kukana

Kukaniza kwa DC kwa conductive pachimake chomalizaphotovoltaic chingwepa 20 ℃ si wamkulu kuposa 5.09Ω/km.

2. Kuyesa kwamagetsi omiza m'madzi

Chingwe chomalizidwa (20m) chimamizidwa m'madzi (20 ± 5) ℃ kwa 1h ndiyeno kuyesedwa kwa 5min voteji (AC 6.5kV kapena DC 15kV) popanda kusweka.

3. Kukana kwamagetsi kwa DC kwa nthawi yaitali

Chitsanzocho ndi chautali wa 5m ndipo chimayikidwa m'madzi osungunuka omwe ali ndi 3% sodium chloride (NaCl) pa (85±2) ℃ kwa (240±2)h, mbali zonse ziwiri zimawonekera pamwamba pamadzi kwa 30cm. Magetsi a DC a 0.9kV amagwiritsidwa ntchito pakati pa pachimake ndi madzi (co conductive core imalumikizidwa ndi mtengo wabwino ndipo madziwo amalumikizidwa ndi pole). Mukatenga chitsanzo, kuyesa kwamagetsi omiza m'madzi kumachitika, voteji yoyesa ndi AC 1kV, ndipo palibe kuwonongeka komwe kumafunikira.

4. Insulation resistance

Kukaniza kukana kwa chingwe chomalizidwa cha photovoltaic pa 20 ° C sichiyenera kukhala chochepera 1014Ω · cm,

Kukaniza kukana kwa chingwe chomalizidwa pa 90 ° C sikuyenera kukhala pansi pa 1011Ω · cm.

5. M'chimake pamwamba kukana

Kukaniza pamwamba pa chingwe chomalizidwa sikuyenera kuchepera 109Ω.
