Ngophuhliso olukhawulezayo lweshishini elitsha lamandla, ukuveliswa kwamandla e-photovoltaic kuninzi kwaye kusetyenziswe ngokubanzi.Njengenxalenye ephambili yeenkqubo zokuvelisa amandla e-photovoltaic, ii-inverters ze-photovoltaic zisebenza kwiindawo zangaphandle, kwaye ziphantsi kovavanyo olunzima kakhulu kunye nobunzima beendawo.
Kwii-inverters ze-PV zangaphandle, uyilo lwesakhiwo kufuneka luhlangabezane nomgangatho we-IP65.Kuphela ngokufikelela kulo mgangatho unokuthi ii-inverters zethu zisebenze ngokukhuselekileyo nangokufanelekileyo.Ukulinganisa kwe-IP kukwinqanaba lokukhusela lezinto zangaphandle kwindawo evalelwe izixhobo zombane.Umthombo ngumgangatho we-International Electrotechnical Commission we-IEC 60529. Lo mgangatho waphinda wamkelwa njengomgangatho welizwe lase-US ngo-2004. Sihlala sisithi inqanaba le-IP65, i-IP sisishunqulelo soKhuseleko lokuNgena, apho i-6 inqanaba lothuli, (6) : ukuthintela ngokupheleleyo uthuli ekungeneni);I-5 yinqanaba lokungangeni manzi, (5: amanzi ahlamba imveliso ngaphandle komonakalo).
Ukuze ufezekise ezi mfuno zoyilo ngasentla, iimfuno zoyilo lwezakhiwo ze-photovoltaic inverters zingqongqo kakhulu kwaye zinengqiqo.Oku kukwayingxaki ekulula kakhulu ukubangela iingxaki kwizicelo zentsimi.Ke siyenza njani imveliso yoguqulo olufanelekileyo?
Okwangoku, kukho iintlobo ezimbini zeendlela zokukhusela ezisetyenziswa ngokuqhelekileyo ekukhuselweni phakathi kwekhava ephezulu kunye nebhokisi ye-inverter kwishishini.Enye kukusetyenziswa kweringi ye-silicone engenamanzi.Olu hlobo lwesangqa se-silicone esingangeni manzi ngokubanzi luyi-2mm ubukhulu kwaye ludlula kwikhava ephezulu kunye nebhokisi.Ukucinezela ukufikelela kwisiphumo sokungangeni kwamanzi kunye nothuli.Olu hlobo loyilo lokukhusela lukhawulelwe ngumlinganiselo we-deformation kunye nobunzima be-silicone yerubha engenamanzi, kwaye ifanelekile kuphela kwiibhokisi ezincinci ze-inverter ze-1-2 KW.Iikhabhinethi ezinkulu zineengozi ezifihlakeleyo ngakumbi kwimpembelelo yazo yokukhusela.
Lo mzobo ulandelayo ubonisa:
Enye ikhuselwe yi-German Lanpu (RAMPF) i-polyurethane styrofoam, eyamkela ukubumba kwe-foam yokulawula amanani kwaye idibaniswe ngokuthe ngqo kwiindawo zesakhiwo ezifana nesigqubuthelo esingaphezulu, kwaye ukuguqulwa kwayo kunokufikelela kwi-50%.Ngaphezulu, ifaneleka ngakumbi kuyilo lokhuseleko lwe-inverters yethu ephakathi kunye nenkulu.
Lo mzobo ulandelayo ubonisa:
Kwangaxeshanye, okona kubalulekileyo, kuyilo lwesakhiwo, ukwenzela ukuba kuqinisekwe uyilo olungenamanzi, igroove engenamanzi iya kuyilwa phakathi kwesigqubuthelo esingaphezulu se-photovoltaic inverter chassis kunye nebhokisi ukuqinisekisa ukuba nangona inkungu yamanzi. idlula kwikhava ephezulu kunye nebhokisi.Kwi-inverter phakathi komzimba, iya kukhokelwa kwakhona kwitanki yamanzi ngaphandle kwamathontsi amanzi, kwaye ugweme ukungena ebhokisini.
Kwiminyaka yakutshanje, kukho ukhuphiswano oluqatha kwimarike ye-photovoltaic.Abanye abavelisi be-inverter benze ezinye izinto ezilula kunye nokutshintsha ukusuka kuyilo lokhuseleko kunye nokusetyenziswa kwezinto eziphathekayo ukuze kulawulwe iindleko.Umzekelo, lo mzobo ulandelayo ubonisa:
Icala lasekhohlo luyilo lokunciphisa iindleko.Umzimba webhokisi ugobile, kwaye iindleko zilawulwa kwiphepha lesinyithi kunye nenkqubo.Xa kuthelekiswa nebhokisi egotywayo kathathu kwicala lasekunene, ngokucacileyo kukho umsele omncinci ovela kwibhokisi.Amandla omzimba nawo aphantsi kakhulu, kwaye olu yilo luzisa amandla amakhulu okusetyenziswa ekusebenzeni kokungena kwamanzi kwe-inverter.
Ukongeza, ngenxa yokuba uyilo lwebhokisi ye-inverter lufezekisa umgangatho wokukhusela we-IP65, kwaye iqondo lokushisa langaphakathi le-inverter liya kwanda ngexesha lokusebenza, umahluko woxinzelelo obangelwa ubushushu obuphezulu bangaphakathi kunye nokutshintsha kwangaphandle kweemeko zokusingqongileyo kuya kukhokelela kumanzi angena kwaye wonakalise ubuthathaka be-elektroniki. amacandelo.Ukuze ugweme le ngxaki, sidla ngokufaka i-valve yokuphefumla engenamanzi kwibhokisi ye-inverter.I-valve engenamanzi kunye neyokuphefumulayo inokulinganisa ngokufanelekileyo uxinzelelo kunye nokunciphisa i-condensation phenomenon kwisixhobo esitywiniweyo, ngelixa ivimbela ukungena kothuli kunye nolwelo.Ukuze kuphuculwe ukhuseleko, ukuthembeka kunye nobomi benkonzo yeemveliso ze-inverter.
Ke ngoko, sinokubona ukuba i-photovoltaic inverter yoyilo lwesakhiwo olufanelekileyo lufuna uyilo olucokisekileyo kunye nolungqongqo kunye nokhetho kungakhathaliseki ukuyilwa kwesakhiwo se-chassis okanye izinto ezisetyenzisiweyo.Kungenjalo, ithotywa ngobumfama ukulawula iindleko.Iimfuno zoyilo zinokuzisa kuphela iingozi ezinkulu ezifihlakeleyo ekusebenzeni okuzinzile kwexesha elide le-photovoltaic inverters.
