Kodi ma inverters a photovoltaic amatha bwanji kupirira kutentha kopitilira 40°C?

Chilimwe chino, madera ambiri ku China adapereka zidziwitso zofiira za kutentha kwambiri, kutentha kwa masana m'mizinda yambiri kukuyandikira 40 ° C, zomwe zimapangitsa kuti zikhale ngati 'ng'anjo yamoto'. M'mikhalidwe yotereyi, ngakhale anthu amavutika kusiya malo okhala ndi mpweya, pomwe zida za photovoltaic zomwe zimagwira ntchito panja zimakumana ndi zovuta zazikulu. Makamaka zokhudzana ndi 'ubongo wapakati' wa ma photovoltaic systems - inverter. Kodi zida zimenezi zimapirira bwanji kutentha kwambiri?

Kodi kutentha kwakukulu kumawononga zida za inverter?

Photovoltaic inverters ndi zida zovuta kuphatikiza zida zambiri zamagetsi zolondola kwambiri, kuphatikiza zida zazikulu monga ma inductors, capacitors, ndi ma semiconductor modules. Kutentha kwakukulu sikumangosokoneza magwiridwe antchito a zigawozi komanso kumathandizira kukalamba, kufupikitsa moyo wawo, ndipo kungayambitsenso kulephera kwa zida.

Ma Inductor: M'malo otentha kwambiri, ma inductor amadzaza mosavuta, zomwe zimachepetsa kukhuta kwawo. Izi zimapangitsa kuti mphamvu yamagetsi ichuluke, zomwe zimawonjezera chiopsezo cha kupitirira muyeso komanso kutha kwa zida zamagetsi.

Ma Capacitors: Makamaka ma capacitors a aluminiyamu, amakhudzidwa kwambiri ndi kutentha. Deta ikusonyeza kuti pa kutentha kulikonse kwa 10°C komwe kumawonjezeka, nthawi yawo ya moyo imachepetsedwa ndi theka. Ngakhale kuti ma capacitors a filimu amasonyeza kukana kutentha kwambiri, zoletsa za mtengo ndi kukula zimalepheretsa kugwiritsidwa ntchito kwawo kwambiri.

Ma Power Modules: Pa ma power chips monga ma IGBTs ndi ma MOSFET, 'kutentha kwa junction' kumagwira ntchito ngati gawo lofunika kwambiri la magwiridwe antchito. Kutentha kwa ma chips kukapitirira malire ake, 'kuwonongeka kwa kutentha' kumachitika, zomwe zimapangitsa kuti inverter izitseke mwachindunji.

Kapangidwe ka Kutentha: Chida Chobisika cha Wopanga Inverter

Kuonetsetsa kuti ntchito yokhazikika m'madera otentha kwambiri, ma inverters a photovoltaic amagwiritsa ntchito makina oyendetsera kutentha omwe amapangidwa mwaluso. Mfundo yaikulu ndi kusunga chigawo chilichonse mkati mwa kutentha kwake kovomerezeka.

Njira zodziwika bwino zoyendetsera kutentha ndi:

Makina oziziritsira mpweya: Okhala ndi mafani anzeru osinthasintha liwiro omwe amasintha mpweya woyenda kutengera kusinthasintha kwa kutentha kwamkati, kulinganiza kuziziritsa kwamphamvu ndi kugwiritsa ntchito mphamvu moyenera komanso kuchepetsa phokoso.

Kukonza bwino sinki yotenthetsera: Kupititsa patsogolo kusinthasintha kwa kutentha mwa kuwonjezera malo a sinki yotenthetsera, kukonza bwino nyumba (monga mapangidwe a zipsepse zopyapyala), ndikugwiritsa ntchito zipangizo zotenthetsera kwambiri.

Kapangidwe ka chassis yolumikizidwa: Mochulukirachulukira, ma inverter apamwamba amagwiritsa ntchito aluminium alloy die-casting kuti agwirizane ndi nyumba zotenthetsera kutentha ndi chassis. Kuphatikiza ndi thermal silicone gel ndi zotenthetsera kutentha, izi zimathandiza kutulutsa kutentha mwachangu.

Mwachitsanzo, ma inverter amtundu wa 'high-temperature tolerant' amakhala ndi zida zoziziritsa za inshuwaransi ziwiri zomwe zimakhala ndi zipsepse zazikulu zakumbuyo ndi mafani anzeru. Izi sizimangowonjezera kusinthasintha m'malo ovuta komanso zimatsimikizira kukhazikika kwadongosolo kwanthawi yayitali.

Njira Zotetezera Kutentha kwa Inverter: Kuika patsogolo Kuyika ndi Kukonza

Kupitilira kukana kutentha kwachilengedwe, malo abwino oyikapo komanso kukonza mosamalitsa ndizofunikanso.

Kusankha Malo Ndikofunikira: Ikani ma inverter m'malo opumira bwino omwe ali ndi mpweya wabwino wotetezedwa ku dzuwa lachindunji. Pakuyika panja, ganizirani kuwonjezera mithunzi ya dzuwa kuti muchepetse kukhudzana ndi dzuwa ndi mvula. Mukayika ma inverter angapo moyandikana, onetsetsani kuti muli ndi malo okwanira kuti kutentha kuchotsedwe bwino.

Kuyeretsa Nthawi Zonse N'kofunika: M'malo otentha kwambiri, fumbi limasonkhana mosavuta pa masinki otenthetsera ndi mafani, zomwe zimapangitsa kuti kuziziritsa kusamagwire bwino ntchito. Ndikoyenera kuyang'ana makina oziziritsira osachepera pamwezi kuti awone ngati fumbi lasonkhana kapena zinthu zina zakunja zatsekedwa, ndikuyeretsa mwachangu ngati kuli kofunikira.

Yang'anirani momwe ntchito ikuyendera: Yang'anani nthawi zonse chowonetsera cha inverter, zizindikiro za LED, ndi makina owunikira akutali kuti muwone machenjezo monga 'machenjezo okhudza kutentha kwambiri' kapena 'mavuto a fan'. Ngati pali zolakwika zilizonse, fufuzani nthawi yomweyo ndikulankhulana ndi akatswiri othandizira pambuyo pa malonda ngati pakufunika.

Malingaliro omaliza: Kutentha kwakukulu si ntchito ya Mulungu, koma kuyesa kwa litmus pamapangidwe adongosolo

Pamene kutentha kwachilimwe kumachulukirachulukira chaka chilichonse ku China, kulimba kwa kutentha kwa inverter kwakhala chizindikiro chofunikira kwambiri chodalirika chazinthu. Kwa eni ake a PV ndi ogwira ntchito ku O&M, kusankha ma inverter apamwamba kwambiri omwe ali ndi kasamalidwe kabwino kamafuta ndikofunikira pakuwonetsetsa kuti dongosolo limakhala lopindulitsa komanso lokhazikika.

Kutentha kwakukulu si mdani—kusakonzekera. Tiyeni titeteze ma inverters athu a PV ndi 'chishango cha kutentha kwa kutentha' kuti tipirire mafunde a chilimwe, kuonetsetsa kuti ola lililonse la kilowatt la mphamvu zobiriwira likuperekedwa modalirika.
