Mfundo yogwirira ntchito ya solar photovoltaic junction box

Solar photovoltaic junction box ndi cholumikizira pakati pa solar cell array yomwe ili ndi ma module a solar cell ndi chipangizo chowongolera dzuŵa.Ndi mawonekedwe ophatikizika ophatikiza magetsi, kapangidwe ka makina ndi sayansi yazinthu.Solar cell module junction box ndi yofunika kwambiri pakupanga gawo la solar, ntchito yayikulu ndikulumikiza magetsi opangidwa ndi dzuwa ku mzere wakunja.Bokosi lolumikizana limamangiriridwa kumbuyo kwa chigawocho ndi gel osakaniza silikoni.Zingwe zotuluka m'chigawocho zimagwirizanitsidwa ndi zingwe zamkati mu bokosi lolumikizirana, ndipo zingwe zamkati zimagwirizanitsidwa ndi zingwe zakunja kuti chigawocho chigwirizane ndi zingwe zakunja.Pali ma diode mu bokosi lolumikizirana kuti zitsimikizire kuti zigawozo zitha kugwira ntchito bwino pomwe kuwala kwatsekedwa.

Bokosi lolumikizira dzuwa limatha kupanga mphamvu yamagetsi pansi pamlingo wina wa kuwala, womwe ungagwiritsidwe ntchito polumikiza zida zamagetsi.Cholinga chake ndi chakuti zomwe zimapangidwira pa nthawi ya unit ndizokulirapo kuposa kugwiritsa ntchito chipangizocho.Muzochitika zenizeni, kugwiritsidwa ntchito kwamtunduwu ndikochepa.Nthawi zambiri amagwiritsidwa ntchito ngati dongosolo lonse.

Mitundu ya ma solar photovoltaic junction boxes

Pakadali pano, bokosi lolumikizana ndi dzuwa limapangidwa makamaka ndi kristalo imodzi, polycrystal ndi amorphous.Pakati pawo, kristalo imodzi ndiyo yabwino kwambiri, yapamwamba kwambiri, mtengo wapamwamba;Kuchita bwino kwa polycrystalline ndi 2% kutsika, mtengo ndi wofanana, ndipo nthawi ya moyo wa awiriwa ndi zaka zoposa 25;Amorphous otsika dzuwa, moyo waufupi, koma wotsika mtengo.Kuchokera pamalingaliro otsika mtengo, kapena kristalo wapamwamba kwambiri.

Makhalidwe akuluakulu ogwira ntchito a solar photovoltaic junction box

Mphamvu ya solar photovoltaic mphambano bokosi anayesedwa pansi mikhalidwe muyezo: kutentha madigiri 25, AM1.5, 1000W/M2.Nthawi zambiri amatanthauzidwa ndi WP, koma amathanso kutchulidwa ndi W. Mphamvu yoyesedwa pansi pa muyezo uwu imatchedwa mphamvu yadzina.

1. Chipolopolocho chimapangidwa ndi zida zotsogola zochokera kunja, zokhala ndi anti-kukalamba kwambiri komanso kukana kwa UV;

2. Ndi yoyenera kugwiritsidwa ntchito panja pansi pa zovuta zachilengedwe, ndipo kugwiritsidwa ntchito kwenikweni ndi zaka zoposa 25.

3. 2 mpaka 6 ma waya amatha kumangidwa momwe amafunira.

4. Mitundu yonse yolumikizira imatengera plug-in yolumikizira mwachangu.
