Li-inverters tsa photovoltaic li khona ho mamella mocheso o chesang o fetang 40 ° C joang?

Lehlabuleng lena, libaka tse ngata ho pholletsa le Chaena li fane ka litlhokomeliso tse khubelu bakeng sa mocheso o feteletseng, ka mocheso oa motšehare metseng e mengata o atamela 40 ° C, e leng se etsang hore maemo a re hopotsa 'sebopi sa mollo'. Maemong a joalo a phoroselang, esita le batho ba sokola ho tloha libakeng tse nang le moea o pholileng, ha lisebelisoa tsa photovoltaic tse sebetsang ka ntle li tobane le mathata a maholo. Haholo-holo mabapi le 'boko ba mantlha' ba sistimi ea photovoltaic - inverter. Lisebelisoa tsee li khona ho mamella mocheso o matla joang?

Mocheso o phahameng o kotsi hakae ho likarolo tsa inverter?

Li-inverters tsa photovoltaic ke lisebelisoa tse rarahaneng tse kopanyang likarolo tse ngata tsa elektronike tse nepahetseng haholo, ho kenyelletsa le likarolo tsa mantlha tse kang li-inductors, li-capacitor le li-module tsa semiconductor tsa matla. Lithempereichara tse phahameng ha li senye feela tšebetso e sebetsang ea likarolo tsena empa hape li potlakisa botsofali ba tsona, li khutsufatsa nako ea tsona ea ho phela, ’me li ka ba tsa baka ho hlōleha ha thepa.

Li-inductors: Libakeng tse nang le mocheso o phahameng, li-inductors li tlala habonolo, li fokotsa matla a tsona a mangata. Sena se lebisa ho litlhōrō tse ntseng li eketseha tsa hona joale, ho eketsa kotsi ea ho feta le ho chesa lisebelisoa tsa motlakase.

Li-Capacitors: Aluminium electrolytic capacitor, haholo-holo, e na le mocheso o phahameng haholo. Lintlha li bontša hore bakeng sa keketseho e 'ngoe le e 'ngoe ea 10 ° C mocheso oa tikoloho, bophelo ba bona bo fokotseha ka halofo. Le hoja li-capacitor tsa filimi li bontša ho hanyetsa mocheso o phahameng, litšenyehelo le boholo ba lithibelo li fokotsa ho amoheloa ha tsona hohle.

Matla a Module: Bakeng sa li-chips tsa motlakase tse kang li-IGBT le li-MOSFET, 'mocheso oa mocheso' o sebetsa e le moeli oa ts'ebetso ea bohlokoa. Hang ha mocheso oa chip o feta moeli oa oona, 'ho senyeha ha mocheso' ho etsahala, ho baka ho koala ha inverter ka ho toba.

Moralo oa Thermal: Sebetsa sa Lekunutu sa Moetsi oa Inverter

Ho etsa bonnete ba ts'ebetso e tsitsitseng libakeng tse phahameng tsa mocheso, li-inverters tsa photovoltaic li sebelisa mekhoa ea tsamaiso ea mocheso e hlophisitsoeng hantle. Molao-motheo oa mantlha ke ho boloka karolo e 'ngoe le e' ngoe ka har'a mocheso o amohelehang oa mocheso.

Mekhoa e tloaelehileng ea ho laola mocheso e kenyelletsa:

Sistimi ea ho futhumatsa moea: E na le libapali tse bohlale tse feto-fetohang tse ikamahanyang le phallo ea moea ka bo eona ho latela ho fetoha ha mocheso ka hare, ho leka-lekanya ho pholisa ka matla le ho sebetsa hantle ha matla le ho fokotsa lerata.

Ho ntlafatsa sink ea mocheso: Ho ntlafatsa bokhoni ba phapanyetsano ea mocheso ka ho eketsa sebaka se tebang sa mocheso, ho hloekisa meaho (mohlala, meralo ea serrated fin), le ho sebelisa lisebelisoa tse nang le mocheso o phahameng oa mocheso.

Moralo oa chassis o kopantsoeng: Ka mokhoa o ntseng o eketseha, li-inverters tsa premium li sebelisa aluminium alloy die-casting ho kopanya meaho ea ho qhala mocheso le chassis. E kopantsoe le gel ea silicone ea mocheso le li-spreaders tsa mocheso, sena se thusa ho ntša mocheso ka potlako.

Mohlala, li-inverters tsa mefuta e 'ngoe ea' 'li mamella mocheso o phahameng' li na le lisebelisoa tsa ho pholisa tsa liinshorense tse peli tse nang le mapheo a ka morao a sebaka se seholo le libapali tse bohlale. Sena ha se matlafatse feela ho ikamahanya le maemo libakeng tse feteletseng empa hape se tiisa botsitso ba nako e telele ea tsamaiso.

Maano a Tšireletso ea Mocheso oa Inverter: Ho Bea Pele ho Kenyeletsoa le Tlhokomelo

Ntle le ho hanyetsa mocheso o phahameng, maemo a nepahetseng a ho kengoa le tlhokomelo e hlokolosi ea kamehla le tsona li bohlokoa.

Litaba tsa Khetho ea Sebaka: Kenya li-inverters libakeng tse nang le moea o motle, tse sirelelitsoeng ke khanya ea letsatsi. Bakeng sa ho kenya ka ntle, nahana ka ho kenya li-sunshades ho fokotsa ho pepesehela mahlaseli a letsatsi le pula. Ha u kenya li-inverters tse ngata ka lehlakoreng le leng, etsa bonnete ba hore sebaka se lekaneng se lekaneng ho tsamaisa mocheso o sebetsang hantle.

Ho Hloekisa Kamehla ho Bohlokoa: Libakeng tse nang le mocheso o phahameng, lerōle le bokellana habonolo holim'a litšepe tsa mocheso le li-fan, tse senyang katleho ea ho pholisa. Ho eletsoa ho hlahloba mokhoa oa ho pholisa bonyane khoeli le khoeli bakeng sa ho bokella lerōle kapa ho thibela lintho tse tsoang kantle ho naha, ho etsa tlhoekiso ea kapele moo ho hlokahalang.

Lekola boemo ba tšebetso: Kamehla hlahloba ponts'o ea inverter, matšoao a LED, le lisebelisoa tsa ho beha leihlo u le hole bakeng sa litlhokomeliso tse kang 'litemoso tse fetang mocheso o feteletseng' kapa 'ho se sebetse hantle ha fan'. Haeba ho ka hlaha mathata, etsa lipatlisiso hang-hang 'me u ikopanye le tšehetso ea morao-rao ea thekiso haeba ho hlokahala.

Mehopolo ea ho qetela: Lithempereichara tse phahameng ha se ketso ea Molimo, empa ke teko ea litmus bakeng sa moralo oa sistimi

Ha mocheso oa lehlabula o ntse o eketseha selemo le selemo ho pholletsa le China, ho tiea ha mocheso oa inverter ho fetohile letšoao la bohlokoa bakeng sa ho tšepahala ha sehlahisoa. Bakeng sa beng ba limela tsa PV le basebetsi ba O&M, ho khetha li-inverter tsa boleng bo holimo tse nang le taolo e phahameng ea mocheso ke ntho ea bohlokoa ho netefatsa phaello le botsitso ba sistimi.

Lithempereichara tse phahameng hase sera—ho se itokise. A re sireletseng li-inverters tsa rona tsa PV ka 'thebe ea mocheso oa mocheso' ho mamella maqhubu a chesang a lehlabula, ho netefatsa hore hora e 'ngoe le e 'ngoe ea kilowatt ea matla a tala e fanoa ka botšepehi.
