Kapangidwe ndi Ntchito Zazikulu za Solar Panel Connection Box

       Mabokosi olumikizana ndi solar panelamagwiritsidwa ntchito ndi akatswiri amagetsi kuteteza zingwe kuti zisagwedezeke ndi kulumidwa ndi tizilombo pogwiritsa ntchito njira zakunja kwa zingwezo.Ndipo polumikiza chingwe (kapena pakona ya chitoliro cha chingwe), gwiritsani ntchito bokosi lolowera ngati kusintha.Machubu awiri a chingwe amalumikizidwa ku bokosi lolumikizirana, ndipo zingwe zomwe zili mkati mwa machubu zimalumikizidwa mkati mwa bokosi lolumikizirana.Bokosi lolumikizira dzuwa limagwira ntchito yoteteza ndi kulumikiza zingwe.

Ntchito ya bokosi la Solar junction ndikulumikiza magetsi opangidwa ndi gawo la PV ku waya wakunja.Popeza mapanelo adzuwa nthawi zambiri amafunika kugwiritsidwa ntchito m'malo ovuta ndipo amakhala ndi chitsimikizo mpaka zaka 25, ma solar amakhalanso ndi zofunika kwambiri pamabokosi olumikizirana.Kuwonjezera kuonetsetsa kudalirika kwa kugwirizana, kuonetsetsa chitetezo cha mawaya mkati, solar panel kugwirizana bokosi ayeneranso kukhala mkulu odana ndi ukalamba, anti-UV mphamvu;kukhala ndi mulingo wambiri wosalowa madzi komanso wosalowa fumbi, nthawi zambiri kukwaniritsa IP67 kapena kupitilira apo;akhoza kupirira mkulu panopa (nthawi zambiri amafuna kuposa 20A), mkulu voteji (nthawi zambiri 1000 volts, mankhwala ambiri akhoza kufika volts 1500);ntchito osiyanasiyana kutentha (-40 ℃ ~ 85 ℃), otsika kutentha kutentha ndi mndandanda wa zofunika.Komanso, kuti muchepetse ndikupewa kutentha kwa malo otentha, ma diode amaphatikizidwa mkati mwa bokosi lolumikizana ndi solar.

Mapangidwe a pv panel junction box: chivundikiro cha bokosi (kuphatikiza mphete yosindikizira), thupi la bokosi, ma terminals, ma diode, zingwe, ndi zolumikizira.

Kapangidwe ka Solar Panel Connection Box

1. Thupi la bokosi ndi chivundikiro cha bokosi lolumikizirana

Zida zoyambira za bokosi la bokosi ndi chivundikiro cha bokosi lolumikizana ndi solar panel zimagwiritsidwa ntchito PPO, yomwe ili ndi zabwino zolimba, kukana kutentha kwambiri, kusayaka, mphamvu yayikulu komanso mphamvu zabwino kwambiri zamagetsi.Kuonjezera apo, PPO imakhalanso ndi ubwino wa kukana kuvala, kusakhala ndi poizoni, kukana kuwononga chilengedwe, kukana kwa nyengo yabwino, ndi zina zotero. PPO ili ndi imodzi mwazitsulo zazing'ono kwambiri za dielectric ndi kutayika kwa dielectric pakati pa mapulasitiki a engineering, ndipo sichimakhudzidwa ndi kutentha ndi chinyezi, kulola iyenera kugwiritsidwa ntchito m'magawo amagetsi otsika, apakati komanso apamwamba kwambiri.PPO yoyera yosasinthika imakhala ndi kukhuthala kwakukulu, kusasunthika bwino komanso kusinthika, ndipo sikungapangidwe ndi makina opangira jakisoni.Pofuna kuthetsa vutoli, PPO ikhoza kusinthidwa ndi njira zakuthupi kapena zamankhwala, ndipo PPO yosinthidwa imatchedwa MPPO.Hot melt mtundu MPPO amawumbidwa ndi jekeseni akamaumba makina kupanga bokosi thupi.Njira yopangira chivundikirocho ndi yofanana ndi thupi la bokosi, nkhungu yokha ndiyosiyana.Kupititsa patsogolo magwiridwe antchito amadzi, chivindikirocho chimakhala ndi chisindikizo chopangidwa ndi silikoni.

2. Pokwerera

Mbali yolowera ya terminal imalumikizidwa ndi sink bar ya solar panel, ndipo mbali yotuluka imalumikizidwa ndi chingwe.Zida za pothera nthawi zambiri zimakhala zamkuwa wangwiro kapena zamkuwa, mkuwa wokutidwa ndi malata ndi wamkuwa wokhala ndi chitsulo chopyapyala chachitsulo pamwamba.Tin makamaka amagwira ntchito kuteteza mkuwa kuteteza mkuwa kuti oxidized kupanga mkuwa wobiriwira kukhudza madutsidwe.Nthawi yomweyo, malo otsika osungunuka a malata, osavuta kuwotcherera, komanso kuwongolera bwino kwamagetsi, mutha kugwiritsanso ntchito mkuwa wokutidwa ndi chromium kuti mupange cholumikizira.

3. Diode

Ma diode ali ndi mawonekedwe a conductor amodzi.Ma diode amatha kugawidwa ngati ma diode owongolera, ma diode othamanga, ma diode owongolera ma voltage ndi ma diode otulutsa kuwala.

4. PV Chingwe

Zingwe zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi ma conductor a mkuwa kapena malata mkati ndi zigawo ziwiri zoteteza kunja, zomwe ndi polyvinyl chloride (PVC) insulation plus PVC jacket, koma PVC simakwaniritsa zofunikira za ukalamba ndipo imakhala ndi halogen, yomwe imatulutsa mpweya wa chlorine ukatenthedwa ndipo siwotetezeka kwambiri.Photovoltaic zingwe amafunika owala mtanda zogwirizana polyolefins kuwonjezera kondakitala (kulumikizana ndi ukadaulo wolumikizira kuwoloka kumatanthawuza momwe zimalumikizirana ndi ma macromolecules zomwe zimatheka kudzera pakuwunikira, kotero kuti polima liniya amakhala polima wokhala ndi mawonekedwe atatu digiri danga maukonde, kotero kuti Kutentha kwake kovomerezeka kwa nthawi yayitali kumawonjezeka kuchoka pa 70 ° C kufika ku 90 ° C, ndipo kutentha kwafupipafupi kumawonjezeka kuchoka pa 140 ° C kufika ku 250 ° C, ndikusunga mphamvu zake zoyambirira zamagetsi ndikuwongolera kugwiritsira ntchito kwenikweni ntchito. ) Mkati mwa chingwe cha photovoltaic ndi waya wamkuwa wokhala ndi gawo la 4mm2.Ngati mphamvu yamtundu wa solar panel (osakwana 10 amps) imawerengedwa, waya wamkuwa wa 2.5mm2 ndi wokwanira, koma poganizira kuti mapanelo a dzuwa nthawi zambiri amagwira ntchito pansi pa kutentha kwakukulu, pamene mphamvu ya chingwe imachepetsedwa ndipo dongosolo lamakono ndilokwera kwambiri. , malo okulirapo a waya wamkuwa ayenera kugwiritsidwa ntchito kuonetsetsa chitetezo cha dongosolo.

5. Cholumikizira

Zolumikizira zimatchinga kapena kudzipatula pakati pa mabwalo, kutsekereza kuyenda kwaposachedwa kuti dera likwaniritse zomwe akufuna.Zolumikizira ziwiri zimakhala ndi cholumikizira chachimuna ndi cholumikizira chachikazi, chogwiritsa ntchito PPO ngati zida zotetezera.Cholumikizira chachimuna chimagwiritsidwa ntchito ngati cholumikizira chabwino cha chigawocho ndipo cholumikizira chachikazi chimagwiritsidwa ntchito ngati cholumikizira cholakwika.

6. Glue wa Potting

Mabokosi ambiri olumikizira dzuwa amagwiritsa ntchito zomatira za silicone kuti ateteze zida zawo zamkati ndikuwongolera magwiridwe antchito amafuta.Junction box potting zomatira ndizokhazikika pazigawo ziwiri za silicone.Silicone yokhala ndi zigawo ziwiri imapangidwa ndi guluu A, B mitundu iwiri ya guluu, Guluu wamtundu wina umatchedwa guluu wapansi, gulu B la guluu amatchedwa wochiritsa.Guluu wamtundu wa AB ukasakanizidwa mugawo lina musanagwiritse ntchito, umayikidwa m'bokosi lolumikizirana kuti muchiritsidwe mutasakanikirana.Njira yosakaniza iyenera kukhala yosamala kwambiri kuti muchepetse kusakaniza kwa mpweya.Zomatira zomatira za silicone zimatha kuchiritsidwa kutentha (25 ℃) kapena potenthetsa.Kutentha kwa chipinda kuchiritsa zomatira zomata kungathenso kufulumizitsidwa ndi kutentha.Mankhwalawa ayenera kusakanizidwa musanagwiritse ntchito, chifukwa mvula imatha kuchitika panthawi yobereka ndi kusunga.Mankhwalawa amatha kuchitapo kanthu ndi chinyezi mumlengalenga, choncho chisamaliro chowonjezereka chiyenera kuchitidwa kuti musagwirizane ndi mpweya musanagwiritse ntchito.

Ntchito ya Solar Connection Box

1. MPPT ntchito: konza pazipita mphamvu kutsatira luso ndi kulamulira chipangizo gulu lililonse kudzera mapulogalamu ndi hardware, luso limeneli akhoza kukulitsa kuthekera kwa kupititsa patsogolo mphamvu mphamvu mphamvu kuchepetsa wa siteshoni mphamvu chifukwa cha makhalidwe osiyanasiyana gulu arrays, ndi kuchepetsa "Mtsuko wa mbiya" pamagetsi opangira magetsi, ukhoza kuonjezera mphamvu yopangira magetsi pa siteshoni yamagetsi.Kuchokera pazotsatira zoyeserera, mphamvu yayikulu yopangira mphamvu zamakina imatha kukulitsidwa ndi 47.5%, ndikuwonjezera kubweza ndalama ndikuchepetsa kwambiri nthawi yobwezera.

2. Kutsekera kwanzeru pazikhalidwe zachilendo monga moto: Kukayaka moto, pulogalamu yolumikizira bokosi la solar idzagwirizana ndi dera la hardware kuti zitsimikizire mkati mwa 10 milliseconds ngati vuto lachitika, ndikuyambapo kudula kugwirizana pakati pa gulu lirilonse, voteji ya 1000V mpaka pafupifupi 40V voteji zovomerezeka anthu kuonetsetsa chitetezo cha ozimitsa moto.

3. Kugwiritsa ntchito MOSFET thyristor Integrated control technology, m'malo mwa chikhalidwe Schottky diode.Pamene mthunzi umachitika, mutha kuyambitsa nthawi yomweyo MOSFET yodutsa pano kuti muteteze chitetezo cha gululo, pomwe MOSFET chifukwa cha mawonekedwe ake otsika a VF, kotero kuti m'badwo wonse wa kutentha m'bokosi lolumikizana ndi gawo limodzi mwa magawo khumi a bokosi lolumikizana. , teknoloji imakulitsa kwambiri moyo wautumiki wa bokosi lolumikizirana, kuteteza bwino moyo wa batri.
