Kufunika kwa ma diode a photovoltaic pakupanga mphamvu ya dzuwa

M'magawo apakati a cell solar, diode ndi chipangizo chodziwika bwino, diode yomwe imagwiritsidwa ntchito kwambiri ndi silicon rectifier diode, posankha zofunikira kuti musunge magawo, kupewa kuwonongeka.Nthawi zambiri, voteji yam'mbuyo yakuwonongeka komanso kuchuluka kwaposachedwa kuyenera kupitilira nthawi za 2 za voteji yomwe imagwira ntchito komanso yomwe ikugwira ntchito.Pali mitundu iwiri ikuluikulu ya ma diode mu machitidwe a photovoltaics.

Diode yoletsa kubweza mobwerera (kupewa kubweza kwapano)

Imodzi mwa ntchito za Diode popewa kupewa kulipiritsa m'mbuyo (kupewa kubweza reverse) ndikuletsa kuti ma cell a solar asasunthidwe kupita ku cell solar kapena masikweya array pomwe cell solar kapena square array sikupanga magetsi. Udindo uli mu gulu la batri, kuteteza zomwe zilipo pakati pa nthambi za gulu losinthidwa.Izi ndichifukwa choti voteji ya nthambi iliyonse pamndandanda sangakhale wofanana, nthawi zonse pamakhala kusiyana pakati pa voteji yayikulu ndi yotsika panthambi iliyonse, kapena voteji ya nthambi imatsitsidwa chifukwa cha vuto la nthambi imodzi, shading. , etc. , panopa wa mkulu voteji nthambi idzayenda ku low voltage nthambi ndipo ngakhale kuchepetsa okwana linanena bungwe voteji wa lalikulu array.Chodabwitsa ichi chikhoza kupewedwa mwa kulumikiza ma diode odana ndi kumbuyo-kudzaza mndandanda munthambi iliyonse.

Slocable'sAnti-Reverse Diodeali ndi voteji ovotera 1600V, magetsi kudzipatula voteji mpaka 3100V pakati chip ndi gawo lapansi, galasi passivated Chip soldered, makhalidwe abwino kutentha ndi mphamvu kupalasa njinga, ndi silicon carbide diode, kuposa wamba ma diode mphamvu yoposa 15. %.Kuvotera panopa mpaka 55 A. Ngati dongosolo lanu lili ndi chiwerengero chamakono choposa 12A, diode iyi ikulimbikitsidwa kuteteza zigawo zanu.

Bypass diode

Pamene ma modules a ma cell a solar amalumikizidwa motsatizana kuti apange nthambi ya gulu la ma cell kapena gulu la cell, ma diode amodzi (kapena awiri kapena atatu) amayenera kulumikizidwa motsatana motsatana pazotsatira zabwino ndi zoyipa za gulu lililonse, diode iyi. , yomwe imagwirizanitsidwa mofanana pa malekezero onse a Msonkhano, amatchedwa bypass diode.

Udindo wa bypass diode ndikuletsa chigawo kapena gawo la gawo lalikulu mumzerewu kuti zisasunthike kapena kuyimitsidwa kukupanga mphamvu pakagwa kulephera, mndandanda wazinthu zomwe zilipo zimadutsa zida zolakwika ndikudutsa mu diode popanda. kukhudza kupanga mphamvu kwa zigawo zina zabwinobwino, komanso kuteteza zida zolambalalitsidwa ku kukondera kwapamwamba kapena kuwonongeka chifukwa cha“Hot malo zotsatira”kutentha.

Bypass diode nthawi zambiri imayikidwa mwachindunji mubokosi lolumikizirana, malinga ndi kukula kwa gawo la mphamvu ndi kuchuluka kwa mabatire, kuyika kwa 1 ~ 3 diode.

The by-pass diode sikufunika muzochitika zilizonse, pamene zigawozo zimagwiritsidwa ntchito zokha kapena zofanana, sikoyenera kulumikiza diode.Pazigawo zingapo zotsatizana komanso malo abwino ogwirira ntchito, mutha kuganiziranso kugwiritsa ntchito ma bypass diode.
