M'chilimwe, zomera zamphamvu za photovoltaic zimakhudzidwa ndi nyengo yovuta monga kutentha, mphezi ndi mvula yambiri.Momwe mungasinthire kukhazikika kwa mafakitale amagetsi a photovoltaic kuchokera pamawonekedwe a inverter, kapangidwe kake ndi kapangidwe ka magetsi?
01
Nyengo yotentha
-
Chaka chino, chochitika cha El Niño chikhoza kuchitika, kapena chilimwe chotentha kwambiri m'mbiri yakale chidzabweretsa, zomwe zidzabweretse mavuto aakulu kwa zomera zamagetsi za photovoltaic.
1.1 Zotsatira za kutentha kwakukulu pazigawo
Kutentha kwakukulu kudzachepetsa magwiridwe antchito ndi moyo wa zigawo, monga ma inductors, ma electrolytic capacitors, ma module amphamvu, ndi zina zambiri.
Inductance:Pa kutentha kwakukulu, inductance imakhala yosavuta kukhutitsidwa, ndipo inductance yodzaza idzachepa, zomwe zimabweretsa kuwonjezeka kwa mtengo wapamwamba wa ntchito yamakono, ndi kuwonongeka kwa chipangizo chamagetsi chifukwa cha kupitirira.
Capacitor:Kwa ma electrolytic capacitor, nthawi ya moyo ya ma electrolytic capacitor imachepetsedwa ndi theka pamene kutentha kwapakati kumakwera ndi 10°C.Aluminium electrolytic capacitor nthawi zambiri amagwiritsa ntchito kutentha kwa -25~+105°C, ndipo ma capacitor opanga mafilimu nthawi zambiri amagwiritsa ntchito kutentha kwa -40~+105°C.Chifukwa chake, ma inverters ang'onoang'ono nthawi zambiri amagwiritsa ntchito ma capacitor a filimu kuti azitha kusintha ma inverters mpaka kutentha kwambiri.
Moyo wa capacitors pa kutentha kosiyana
Power module:Kutentha kwapamwamba, kumapangitsanso kutentha kwa chip pamene gawo la mphamvu likugwira ntchito, zomwe zimapangitsa kuti gawoli likhale ndi kupsinjika kwakukulu kwa kutentha ndikufupikitsa kwambiri moyo wautumiki.Kutentha kukadutsa malire a kutentha kwapakati, kumayambitsa kuwonongeka kwa module.
1.2 Njira za Kutentha kwa Inverter
Inverter imatha kugwira ntchito panja pa 45 ° C kapena kutentha kwambiri.Mapangidwe a kutentha kwa inverter ndi njira yofunikira yowonetsetsa kuti ntchito yokhazikika, yotetezeka komanso yodalirika ya gawo lililonse lamagetsi muzogulitsa mkati mwa kutentha kwa ntchito.Kutentha kwa kutentha kwa inverter ndi inductor yowonjezereka, inverter inductor, ndi module ya IGBT, ndipo kutentha kumachotsedwa kupyolera mu fani yakunja ndi kumbuyo kwa kutentha kwambuyo.Zotsatirazi ndi zokhotakhota kutentha kwa GW50KS-MT:
Kutsika kwa kutentha kwa inverter ndi kutsika kwa katundu
1.3 Kumanga njira yolimbana ndi kutentha kwakukulu
Padenga la mafakitale, kutentha kumakhala kokwera kwambiri kuposa pansi.Pofuna kuteteza inverter kuti isawonekere ndi kuwala kwa dzuwa, inverter nthawi zambiri imayikidwa pamalo amthunzi kapena chododometsa chimawonjezeredwa pamwamba pa inverter.Tiyenera kukumbukira kuti malo ogwirira ntchito ndi kukonzanso ayenera kusungidwa pamalo omwe fani ya inverter imalowa ndikutuluka mphepo ndi fani yakunja.Zotsatirazi ndi inverter yokhala ndi mpweya wakumanzere ndi kumanja ndikutuluka.Ndikofunikira kusunga malo okwanira mbali zonse za inverter, ndikusunga mtunda woyenera pakati pa visor ya dzuwa ndi pamwamba pa inverter.

Tmphepo yamkuntho
-
Mphepo yamkuntho ndi mvula m'chilimwe.
2.1 Njira Zoteteza Mvula ya Inverter ndi Chitetezo cha Mvula
Njira zotetezera mphezi za inverter:Mbali za AC ndi DC za inverter zili ndi zida zapamwamba zoteteza mphezi, ndipo zowuma zowuma zimakhala ndi ma alarm oteteza mphezi, zomwe zimakhala zosavuta kuti kumbuyo kudziwe momwe chitetezo champhezi chilili.
Njira zoteteza mvula ndi anti-corrosion inverter:Inverter imatenga mlingo wapamwamba wa chitetezo cha IP66 ndi C4 & C5 anti-corrosion level kuti zitsimikizire kuti inverter ikupitiriza kugwira ntchito pansi pa mvula yambiri.
Kulumikizana kwabodza kwa cholumikizira cha photovoltaic, kulowa kwa madzi pambuyo pa chingwe kuonongeka, zomwe zimapangitsa kuti pakhale dera lalifupi kumbali ya DC kapena kutsika kwapansi, zomwe zimapangitsa kuti inverter asiye.Chifukwa chake, ntchito yozindikira arc ya DC ya inverter ndiyofunikanso kwambiri.
2.2 Njira yonse yoteteza mphezi (yomanga).
Chitani ntchito yabwino yapadziko lapansi, kuphatikiza ma terminals ndi ma inverters.
Miyezo yoteteza mphezi pa solar panel ndi inverter
Mvula yamvula imathanso kupangitsa kuti udzu ukule ndikupangitsa kuti pakhale mthunzi.Pamene madzi amvula amatsuka zigawozo, zimakhala zosavuta kuyambitsa fumbi m'mphepete mwa zigawozo, zomwe zidzakhudza ntchito yoyeretsa yotsatira.
Chitani ntchito yabwino poyang'anira dongosolo, fufuzani nthawi zonse za kutchinjiriza ndi zinthu zosalowa madzi za zolumikizira za photovoltaic ndi zingwe, onani ngati zingwezo zanyowa pang'ono m'madzi amvula, komanso ngati pali ukalamba ndi ming'alu ya chingwe chotchinga.
Kupanga magetsi kwa Photovoltaic ndikopanga mphamvu zanyengo zonse.Kutentha kwakukulu ndi mvula yamkuntho m'chilimwe zabweretsa zovuta kwambiri pakugwira ntchito ndi kukonza magetsi a photovoltaic.Kuphatikiza inverter ndi mapangidwe onse opanga magetsi, Xiaogu amapereka malingaliro omanga, ntchito ndi kukonza, ndipo akuyembekeza kukhala othandiza kwa aliyense.
