PV array DC isolator, yomwe imadziwikanso kuti DC disconnect switch kapena DC isolator switch, ndi chipangizo chomwe chimagwiritsidwa ntchito pamakina a photovoltaic (PV) kuti apereke njira yothetsera mphamvu yachindunji (DC) yopangidwa ndi magetsi a dzuwa kuchokera kuzinthu zonse.Ndi gawo lofunikira lachitetezo lomwe limalola ogwira ntchito yosamalira kapena oyankha mwadzidzidzi kuti alekanitse gulu la PV kuchokera ku inverter ndi zida zina pofuna kukonza kapena kuthetsa mavuto.
Nazi mfundo zazikulu za PV array DC isolators:
Cholinga: Cholinga chachikulu cha PV array DC isolator ndikupereka njira yotetezeka yolumikizira magetsi a DC opangidwa ndi ma solar amagetsi ena onse.Imawonetsetsa kuti palibe mphamvu ya DC yomwe ilipo kumbali ya dongosolo panthawi yokonza kapena pakagwa mwadzidzidzi.
Malo: PV array DC isolators nthawi zambiri imayikidwa pafupi ndi mapanelo a dzuwa kapena pomwe mawaya a DC amalowera mnyumbamo kapena chipinda cha zida.Imalola mwayi wopezeka mosavuta komanso kulumikizidwa mwachangu kwa gulu la PV.
Mavoti amagetsi: PV array DC isolator amavotera kuti agwire ma voliyumu ndi magawo apano a PV system.Miyezo iyenera kufanana kapena kupitilira mphamvu yayikulu komanso yapano ya gulu la PV kuti zitsimikizire kuti ntchito yotetezeka komanso yodalirika.
Kugwira ntchito pamanja: PV array DC isolator nthawi zambiri imakhala ma switch pamanja.Amatha kuyatsa kapena kuzimitsa potembenuza chogwirira kapena kuzungulira chogwirira.Wodzipatula akachoka, amaphwanya dera la DC ndikupatula gulu la PV kuchokera kudongosolo lonselo.
Zolinga zachitetezo: PV array DC isolators adapangidwa ndi chitetezo m'malingaliro.Nthawi zambiri amakhala ndi zinthu monga zogwirira zokhoma kapena zotsekera kuti asalowe kapena kusokoneza mosaloledwa.Odzipatula ena amakhalanso ndi zizindikiro zowoneka kuti asonyeze momwe kusinthaku kulili, kusonyeza ngati gulu la PV likugwirizana kapena kuchotsedwa.
Kutsata miyezo: Odzipatula a PV array DC akuyenera kutsatira miyezo ndi malamulo oyenera, monga National Electrical Code (NEC) kapena International Electrotechnical Commission (IEC) miyezo, kutengera mphamvu.Kutsatira kumatsimikizira kuti wodzipatula akukwaniritsa zofunikira zachitetezo.
Ndikofunika kukaonana ndi katswiri wamagetsi kapena woyikira mphamvu ya solar posankha ndi kukhazikitsa PV array DC isolator kuti muwonetsetse kuti makulidwe oyenera, kuyika, ndi kutsata malamulo ndi malamulo amagetsi apafupi,CHONCHO NDAKONDWERERA KUTI TIPEZE PA ZOFUNIKA KWANU KWApadera: https://www.cncele.com/
