Iyo Yepamusoro-Yazvino Photovoltaic Junction Bhokisi ine Yakazara Met iyo 210 PV Module Zvinodiwa.

Nekugadzirwa kwakawanda kwe166, 182, uye 210 photovoltaic modules, indasitiri inoramba ichikurukura zvakanakira nekuipira kwesilicon wafer saizi shanduko.Chinangwa chehurukuro chinosanganisira magetsi emagetsi uye zviyero zvemamodules, kutakura, uye kushandiswa kwezvinhu zvakasvibirira.Zvechokwadi, kunewo dzimwe nhaurirano pamusoro pekuvimbika uye kusarudzwa kwezvinhu zve photovoltaic junction mabhokisi.Semutengesi wezvinhu ari kuita mukutsvagisa nekusimudzira uye kugadzira kwemabhokisi ejunction kwenguva yakareba, isu tinoongorora hukama pakati pemabhokisi ejunction uye hombe-saizi silicon wafers uye yakakwirira-simba modules kubva pakuona kwezvinhu.

Kushanda Nheyo ye Photovoltaic Junction Box

Basa guru rephotovoltaic junction boxndeyekuburitsa simba rinogadzirwa neiyo photovoltaic module kune rekunze redunhu, kusanganisira goko, diode, mc4 connector, photovoltaic cable uye zvimwe zvikamu, pakati peiyo diode ndiyo musimboti mudziyo.Kana iyo module iri kushanda zvakajairika, iyo diode muPV junction bhokisi iri mune reverse blocking state;kana iyo module cell yakavharwa kana kukuvadzwa, iyo bypass diode inovhurwa kuchengetedza iyo yese photovoltaic module.

Tafura iri pamusoro inoratidza maitiro emagetsi emagetsi e166, 182 uye 210 modules uye kusarudzwa kwehuwandu hwemazuva ano e photovoltaic junction box ye photovoltaic module factory.Iyo module paramita inoratidza yakaderera ikozvino, yakakwira voltage uye yakakwira ikozvino uye yakaderera voltage zvichiteerana.

Photovoltaic Junction Bhokisi uye Diode

Zviratidzo zvakakosha zve photovoltaic junction box zvinosanganisira junction box rated current, diode rated current uye reverse withstand voltage, nezvimwewo, zvichienderana nekugadzirwa kwebhokisi rejunction uye kusarudzwa kwezvinyorwa zve diode.

Kazhinji, certification uye kuongororwa kwe photovoltaic modules uye junction mabhokisi anobva pane: yakarongwa ikozvino ye solar junction mabhokisi ≥ 1.25 nguva Isc yekusarudza uye kuongororwa, uye imwe margin ichachengetwa.Pasi pemamiriro ekushanda akajairika, iyo junction bhokisi diode iri mune reverse cut-off state.Pasinei ne166 uye 182 zvikamu kana 210 zvikamu, diode haizoiti kana kupisa.Kuenzaniswa nezvikamu mazana maviri negumi, iyo junction box diodes ye182 uye 166 zvikamu zvinotakura zvishoma High reverse bias voltage.

Kana nzvimbo inopisa ikaitika mu photovoltaic module, diode inotungamira mberi uye inogadzira kupisa.Tora iyo 210 module uye 25A junction bhokisi semuenzaniso, apo inobuda ikozvino Isc = 18.6A (yazvino kana iyo chaiyo module iri kushanda iri Imp≈17.5A), tembiricha yejunction inenge 120 ° C.Kunyangwe tichifunga nezvechikamu chemhoteredzo ine chiedza chakakwana, kana iri 1.25 times Isc (23.2A), tembiricha yekusangana kweiyo photovoltaic junction box panguva ino inenge 160 ° C, iyo yakadzikira zvakanyanya kupfuura 200 ° C junction. tembiricha yepamusoro muganho weiyo IEC62790 yakajairwa.Ehe, iyo Isc yemamodules 182 uye 166 yakadzikira zvishoma, uye bhokisi rekusangana rine dhizaini yakafanana ine yakaderera kupisa chizvarwa, uye mabhokisi ekusangana ari munzvimbo yakachengeteka yekushanda saka hapana njodzi.

Kuongorora kwepamusoro ndiko kushanda kwebhokisi re photovoltaic junction munyaya yenzvimbo dzinopisa mu photovoltaic module.Kana ari ma modules, apo shiri kana mashizha anovhara nzvimbo dzinopisa uye nokukurumidza kupera, diode thermal escape ichaitika.Iyo module tambo ichaunza pakarepo reverse bias voltage uye kuvuza ikozvino kune diode, uye yakakwira tambo voltage inounza matambudziko makuru kubhokisi rejunction uye diode.Kubva pamaonero ePV junction bhokisi dhizaini, inonzwisisika bhokisi chimiro dhizaini, nyore kupisa kupisa diode kurongedza uye zvirinani chip sarudzo inogona kugadzirisa aya matambudziko.

Kune maviri-sided modules uye hafu chidimbu mamodules, sezvo rimwe divi reyuniti rakabatana rakafanana kune rimwe nerimwe, sezvakaratidzwa mumufananidzo uri pazasi, kana yenzvimbo inopisa nzvimbo uye kupisa kupukunyuka kunoitika, chikamu chakafanana chinogona kuvharirwa, uye muganho wekuchengetedza. yakachengetedzwa nebhokisi rejunction yakatokura.Maererano nekuverenga, mukana wekuti mativi akaenzana, mberi uye kumashure mativi e-double-sided half-cell module akavharwa panguva imwe chete yakaderera zvakanyanya, iyo inenge yechiitiko che 1 module mu10GW.Naizvozvo, pasi pemamiriro chaiwo, hazvigoneke kuve neiyo junction bhokisi inoshanda yakazara yakazara, uye kuvimbika kunogona kuvimbiswa.

Photovoltaic Connectors uye Cables

Seimwe yemagetsi ekufambisa zvikamu, iyophotovoltaic connectorine basa rekubatanidza kwakabudirira kwechiteshi chemagetsi.Parizvino, iyo yakayerwa ikozvino yezvibatanidza zvinonyanya kushandiswa pamusika zvese zvakakwirira kupfuura 30A, uye iyo yepamusoro inogona kusvika 55A, iyo inokwana kuzadzisa zvinodiwa zvekufambiswa kwemagetsi zvezvinhu zviripo zvesimba repamusoro.Izvo zvakasimbiswa kuti mune 55A module reverse ikozvino overload test ye photovoltaic connector ine yakatemerwa ikozvino ye41A kubva kumugadziri, tembiricha inotariswa i76 ° C, iyo yakaderera zvakanyanya kupfuura iyo 105 ° C RTI kukosha kweiyo mbishi. chekubatanidza.Nekudaro, munzvimbo yepamusoro-yazvino yekushandisa, iyo yekubatanidza yekupedzisira inofanirwawo kuedza kudzivirira zvinogona kuitika senge kuganhurwa kwazvino kunokonzerwa nekupokana kwenzvimbo yepamusoro uye nzvimbo yekusangana yenzvimbo yekupisa.Mhinduro dzinoshanda, dzakadai se: kukwenenzvera kuita kwekubata kwemhete yekondukita, kuvandudza chimiro chese chekubatanidza, kuvandudza kunaka kwetambo crimping pamagumo ekubatanidza, uye kuwedzera tin kaviri inishuwarenzi tekinoroji kune chikamu chekubatanidza.

Forphotovoltaic cables, iyo yakatemerwa ikozvino yetambo dzinoenderana ne EN kana IEC zviyero (4mm2 tambo, iyo yakatemerwa ikozvino ndeye 44A kana iyo nzvimbo iri padhuze neimwe) yakakwirira kwazvo kupfuura yakayerwa ikozvino yeiyo photovoltaic junction box, saka hapana chikonzero kunetseka pamusoro pekuvimbika kwayo.

PV Junction Bhokisi Rekugadzira Maitiro uye Musika Overview

Nekuvandudzwa kwakasimba kweyero yekugadzira uye yemhando yekudzora kugona kweiyo photovoltaic junction mabhokisi, kuita uye kuvimbika kwemabhokisi ekusangana kwakanyatso kuvimbiswa, izvo zvinogona kusangana nezvinodiwa zvehukuru-hukuru silicon wafers uye yakakwirira-simba zvikamu.

1. Mukugadzira uye kugadzirwa kweiyo photovoltaic junction bhokisi, nhamba huru yemaitiro matsva uye matekinoroji matsva akave akasimbiswa mumunda we semiconductor, mota, aerospace, nezvimwe zvinounzwa, senge module yekurongedza tekinoroji, yepakati frequency welding. tekinoroji, nezvimwewo, kuvandudza mashandiro emagetsi uye kupisa kupisa kwejunction box zvigadzirwa kugona.

2. MuPV panel junction box kugadzira maitiro, kuwedzera kutsvagisa nekusimudzira nekudyara kwemidziyo otomatiki kunogona kuve nechokwadi chekugadzirisa, kunaka, uye kudzoreka kwemaitiro, uye kuwana maitiro otomatiki uye emhando yekudzora otomatiki.

3. Zvichienderana nePV junction box yekugadzira ruzivo, tarisa pakusimbisa kutonga kwekuvimbika kwekubatanidza pakati pezvishandiso zvebhokisi rejunction uye manejimendi emhando dzakakosha dzekudzora mapoinzi, sekutonga kweiyo compression ratio panzvimbo yekubatanidza, the kaviri inishuwarenzi process zvinodiwa kuti tinning, uye iyo ultrasonic welding process control, Corona kurapwa, uye yekutarisa yakakosha paramita.

Pamusoro pekuvandudzwa kweiyo photovoltaic junction mabhokisi evagadziri kugona kwavo, vagadziri vechikamu uye vechitatu-bato masangano vari kugara vachivandudza kuyedzwa, kuongorora uye kudzora kwemhando yemabhokisi ejunction uye zvikamu, izvo zvakawedzera kukurudzira kuvandudzwa kwehutongi hwemhando uye R&D kugona. yevagadziri vejunction box.

Kutanga kubva muhafu yekutanga ya2020, masangano ezvitupa akadai seTUV aburitsa 25A uye 30A junction bhokisi zvitupa kune vazhinji vanogadzira PV junction box.Mabheji emabhokisi makuru-azvino akapfuura chitupa uye kuyedzwa kwevechitatu-bato masangano, izvo zvakawedzera kusimbisa kuvimba kwejunction box vagadziri uye photovoltaic module vagadziri.Nekuburitswa kwehukuru hwekugadzira 182 uye 210 hombe silicon wafer modules, iyo inotsigira kugadzirwa kwehukuru hweazvino mabhokisi ejunction ichasimbiswa zvishoma nezvishoma uye kuwedzerwa.

Muchidimbu, kushanda, kuvimbika kuvimbiswa uye kukwanisa kwekugadzira kwepamusoro-ikozvino photovoltaic junction mabhokisi uye zvikamu zvakakura, uye zvinogona kuzadzisa zvakakwana zvinodiwa zvemhando dzakasiyana-siyana dzemashizha makuru e-silicon uye zvikamu zvemasimba makuru.
