Momwe Mungasankhire Zingwe za Photovoltaic za Photovoltaic Systems?

Mtengo wamkuwa wakwera posachedwapa, ndipo mtengo wa zingwe wakweranso.Mu mtengo wonse wa photovoltaic systems, mtengo wa zipangizo mongazingwe za photovoltaicndipo masiwichi adutsa ma inverters, ndipo ndi otsika kuposa zigawo ndi zothandizira.Tikapeza zojambula za kampani yopanga mapangidwe ndikudziwa magawo a mtundu wa waya, makulidwe, mtundu, ndi zina zotero, tikhoza kuyamba kugula ndi mndandanda.Komabe, pali mitundu yambiri ya mawaya, ndipo ogwiritsa ntchito ambiri amadabwa ndi mitundu yambiri ya mawaya.Ndi iti yabwino?

Posankha chingwe cha photovoltaic, choyamba tiyenera kuyang'ana mbali ziwiri: conductor ndi insulating layer.Malingana ngati mbali ziwirizi zili bwino, ubwino wa waya umatsimikiziridwa kukhala wodalirika.

1. Kondakitala

Chotsani kutsekera kwa chingwe kuti muwonetse waya wamkuwa mkati, uyu ndiye kondakitala.Titha kuweruza mtundu wa ma conductor m'njira ziwiri:

01. mtundu

Ngakhale otsogolera onse amatchedwa "mkuwa", sali 100% mkuwa woyera, ndipo padzakhala zonyansa zina.Zonyansa zambiri zomwe zili, zimayipitsitsa kwambiri conductivity ya conductor.Kuchuluka kwa zonyansa zomwe zili mu kondakitala nthawi zambiri zimawonekera mumtundu.

Mkuwa wabwino kwambiri umatchedwa "mkuwa wofiira" kapena "mkuwa wofiira" - monga momwe dzinalo likusonyezera, mtundu wa mkuwa woterewu ndi wofiira, wofiirira, wofiirira-wofiira, wofiira wofiira.

Mkuwa woipa kwambiri, mtundu wake umapepuka komanso umakhala wachikasu kwambiri, womwe umatchedwa "mkuwa."Mkuwa wina ndi wopepuka wachikasu - zonyansa za mkuwawu zakwera kale kwambiri.

Ena mwa iwo ndi oyera, awa ndi mawaya apamwamba kwambiri.Mawaya amkuwa amakutidwa ndi tini, chifukwa chachikulu ndikuletsa mkuwa kuti usakhale ndi oxidizing kupanga patina.Ma conductivity a patina ndi osauka kwambiri, zomwe zimawonjezera kukana ndi kutayika kwa kutentha.Kuphatikiza apo, mawaya amkuwa amatha kuletsanso mphira wotsekerayo kuti asamamatire, akuda ndi kuphulika pachimake, ndikuwongolera kusungunuka kwake.Zingwe za Photovoltaic DC zimakhala ndi mawaya amkuwa okhala ndi malata.

02. makulidwe

Pamene waya wam'mimba mwake ndi wofanana, wowonjezera wochuluka kwambiri, amphamvu kwambiri-poyerekeza ndi makulidwe, woyendetsa yekha ayenera kufananizidwa, ndipo makulidwe a insulating wosanjikiza sayenera kuwonjezeredwa.

Yesani kugwiritsa ntchito zingwe zingapo za waya wosinthasintha.Pali waya umodzi wokha mu chingwe, wotchedwa single core wire, monga BVR-1*6;pali mawaya angapo apakati pa chingwe, monga YJV-3 * 25 + 1 * 16, Amatchedwa waya wamitundu yambiri;waya aliyense wapakati amapangidwa ndi mawaya angapo amkuwa ndipo amatchedwa waya wamitundu yambiri, womwe ndi wofewa komanso woyenera pamagetsi a photovoltaic.Waya wamtundu umodzi ukhoza kudulidwa mwachindunji pa terminal, koma waya wamtundu umodzi ndi wovuta kwambiri ndipo siwoyenera kuyika m'malo omwe ali ndi kachigawo kakang'ono kotembenukira.Kwa mawaya azingwe ang'onoang'ono ochepera 16 masikweya mita, tikulimbikitsidwa kugwiritsa ntchito ma terminals a chingwe ndi ma pliers amanual crimping terminal.Kwa mawaya amitundu yambiri akulu kuposa 16 masikweya mita, tikulimbikitsidwa kugwiritsa ntchito ma terminals apadera a ma hydraulic clamps.

2. Insulation Layer

Wosanjikiza wa mphira kunja kwa waya ndi gawo lotsekera la waya.Ntchito yake ndikulekanitsa woyendetsa mphamvu kuchokera kudziko lakunja, kuteteza mphamvu yamagetsi kutuluka kunja, ndikuletsa anthu akunja kuti asatengeke ndi magetsi.Nthawi zambiri, njira zitatu zotsatirazi zingagwiritsidwe ntchito kuweruza mtundu wa insulating layer:

1) Gwirani, gwirani pamwamba pa gawo lotsekera pang'onopang'ono ndi manja anu.Ngati pamwamba ndi ovuta, zimatsimikizira kuti njira yopangira chiwombankhanga ndi yosauka ndipo imakhala ndi zolakwika monga kuwonongeka kwa magetsi.Kanikizani wosanjikiza wotsekera ndi chala chanu, ndipo ngati chitha kubwereranso mwachangu, zimatsimikizira kuti chotchingiracho chimakhala ndi makulidwe apamwamba komanso kulimba kwabwino.

2) Pindani, tengani chidutswa cha waya, pindani mmbuyo ndi mtsogolo kangapo, ndiyeno muwongole waya kuti muwone.Ngati palibe chotsatira pamwamba pa waya, zimatsimikizira kuti waya ali ndi kulimba bwino.Ngati pamwamba pa wayayo ali ndi indentation yoonekera kapena yoyera kwambiri, zimatsimikizira kuti wayayo ndi yolimba kwambiri.Kukwiriridwa pansi kwa nthawi yayitali, kumakhala kosavuta kukalamba, kufooka, komanso kutulutsa magetsi mosavuta m'tsogolomu.

3) Kuwotcha.Gwiritsani ntchito choyatsira kuti chiziyakabe pawaya mpaka mawayawo ayaka moto.Kenako zimitsani choyatsira ndikuyamba kuyika nthawi-ngati waya atha kuzimitsidwa mkati mwa masekondi 5, zimatsimikizira kuti wayayo ili ndi vuto lamoto.Kupanda kutero, zimatsimikiziridwa kuti mphamvu yobwezeretsa lawi la waya siili yoyenera, dera ladzaza kwambiri kapena dera ndilosavuta kuyambitsa moto.

3. Maluso a Wiring System Photovoltaic

Mzere wa photovoltaic system umagawidwa kukhala gawo la DC ndi gawo la AC.Magawo awiriwa a mzerewo ayenera kukhala ndi mawaya padera.Gawo la DC limalumikizidwa ku zigawozo, ndipo gawo la AC limalumikizidwa ndi gridi.Pali zingwe zambiri za DC m'malo opangira magetsi apakatikati ndi akulu.Kuti zithandizire kukonza mtsogolo, manambala a waya a zingwe ayenera kumangirizidwa.Patulani mawaya amphamvu ndi ofooka.Ngati pali mawaya owonetsera, ayendetseni padera kuti musasokonezedwe.Ndikoyenera kukonzekera mipope ndi milatho, yesetsani kuti musamaulule mawaya, ndipo mawaya opingasa ndi okwera adzawoneka bwino akamayendetsedwa.Yesetsani kuti musakhale ndi zingwe zolumikizira mapaipi ndi milatho, chifukwa kukonza ndizovuta.

Mu machitidwe a photovoltaic, mapulojekiti apanyumba ndi ntchito zazing'ono zamakampani ndi zamalonda, mphamvu ya inverter ili pansi pa 20kW, ndipo malo ozungulira a chingwe chimodzi ali pansi pa 10 square.Ndi bwino ntchitozingwe zambiri za solar.Panthawiyi, sikovuta kuyala komanso kosavuta kusamalira;Mphamvu yosinthira ili pakati pa 20-60kW, ndipo gawo laling'ono la chingwe chimodzi ndiloposa 10 lalikulu ndi zosakwana 35 lalikulu, zomwe zingasankhidwe malinga ndi malo a malo;ngati mphamvu ya inverter ndi yoposa 60 kW ndipo gawo laling'ono la chingwe chimodzi ndiloposa 35 lalikulu, tikulimbikitsidwa kusankha zingwe za Single-core ndizosavuta kugwiritsa ntchito komanso zotsika mtengo pamtengo.
