Chilichonse chimalumikizidwa ndi netiweki ya equipotential. Ma netiwekiwa amayeneranso kulumikizidwa ndi netiweki yanyumbayo.
kukhazikitsa mtundu 2 SPD mu EVSE iliyonse
Mtundu wa 3 SPD umalimbikitsidwanso ku Load Management System (LMS) ngati zida zamagetsi zosazindikira. Mtundu wa 3 SPD uyenera kukhazikitsidwa kutsika kwa mtundu wa 2 SPD (womwe umalimbikitsidwa kapena kufunikira pa switchboard komwe LMS imayikidwa).

Kutetezedwa kwambiri kwa EVSE yakunja - yokhala ndi zoteteza mphezi (LPS) - mwayi wopezeka pagulu

Mkuyu. EV34 - Kutetezedwa kwambiri kwa EVSE panja - ndi njira yoteteza mphezi (LPS) - mwayi wopezeka pagulu

Nyumbayi ili ndi ndodo (zoteteza mphezi) kuteteza nyumbayo.

Pamenepa:

Mtundu wa 1 SPD umafunikira mu switch low voltage switchboard (MLVS)
Mtundu wowonjezera 2 SPD umafunikira pagawo laling'ono (mtunda kawirikawiri> 10m kupita ku MLVS)

Kuphatikiza apo:

EVSE ikalumikizidwa ndi kapangidwe kake:

gwiritsani ntchito zopezera zida zomangira nyumbayo
ngati EVSE ndi yochepera 10m kuchokera pagawo laling'ono, kapena ngati mtundu wa 2 SPD woyikika pagawo laling'ono uli Up <1.25kV (pa I (8/20) = 5kA), palibe chifukwa chowonjezerapo ma SPD ena mu ZOKHUDZA

EVSE ikayikidwa pamalo oimikapo magalimoto, ndikupatsidwa chingwe chamagetsi chapansi:

Chilichonse chimakhala ndi ndodo yokomera.
Chilichonse chimalumikizidwa ndi netiweki ya equipotential. Ma netiwekiwa amayeneranso kulumikizidwa ndi netiweki yanyumbayo.
ikani mtundu 1 + 2 SPD mu EVSE iliyonse

Mtundu wa 3 SPD umalimbikitsidwanso ku Load Management System (LMS) ngati zida zamagetsi zosazindikira. Mtundu wa 3 SPD uyenera kukhazikitsidwa kutsika kwa mtundu wa 2 SPD (womwe umalimbikitsidwa kapena kufunikira pa switchboard komwe LMS imayikidwa).

EV nawuza chitetezo uyenderere
