ZOCHITIKA ZONSE
Choteteza chachiwiri cha photovoltaic DC ndi chipangizo chopangidwa kuti chiteteze mphamvu ya DC photovoltaic mkati mwa bokosi lophatikizira la solar photovoltaic system. Ntchito yake yayikulu ndikuletsa kuwonongeka kwa zida kapena kusagwira bwino ntchito komwe kumachitika chifukwa cha ma surges kapena kusokoneza kwa ma elekitiroma mu ma photovoltaic system.
Woteteza wamtunduwu nthawi zambiri amatsata miyezo yoyenera yoyeserera, monga EN 5053911 ndi GB/18802-31 monga mwafotokozera. Miyezo iyi imalongosola zofunikira zaumisiri ndi zizindikiro zogwirira ntchito zomwe otetezera ayenera kukwaniritsa kuti atsimikizire kuti angathe kuteteza bwino machitidwe a photovoltaic ku zotsatira za ma surges ndi ma surges.
Makhalidwe akuluakulu
1. Malizitsani maziko opangira ma wiring: Izi zikutanthauza kuti mtetezi ali ndi maziko a wiring, zomwe zimapangitsa kuti zikhale zosavuta kuziyika mu photovoltaic system. Kukonzekera kumeneku kumaganizira njira yapadera yopangira mawaya a photovoltaic system, kupereka mwayi woyika.
2. Njira yolumikizira yofanana ndi Y: Kutengera njira yolumikizira yooneka ngati Y kungapewe kuwonongeka kwa chomangira mphezi chifukwa cha kulephera kwa insulation mu dera la jenereta. Njira yolumikizira iyi imatha kuwongolera kukhazikika komanso kudalirika kwadongosolo, kuchepetsa zoopsa zomwe zingachitike chifukwa cha zolakwika za insulation.
3. Chipangizo chapadera cha anti DC arc: Mbaliyi ikufuna kupewa ngozi zomwe zimachitika chifukwa cha ma arcs. DC arc ingayambitse vuto lalikulu la chitetezo m'makina a photovoltaic, kotero zipangizo zapadera zimagwiritsidwa ntchito pofuna kupewa kuchitika kwa arc, potero kumapangitsa chitetezo cha dongosolo.
