Sida dhaqaale ahaan loo doorto fiilooyinka sawir-qaadista ee guriga

In nidaamka photovoltaic, heerkulka ACfiilosidoo kale way ka duwan tahay jawiga kala duwan ee lagu rakibay khadadka. Masaafada u dhaxaysa rookaha iyo barta isku xirka shabakada ayaa kala duwan, taasoo keentay hoos u dhaca danab kala duwan ee fiilada. Heerkulka iyo hoos u dhaca danabku labaduba waxay saamayn doonaan luminta nidaamka. Sidaa darteed, waxaa lagama maarmaan ah in si macquul ah loo naqshadeeyo dhexroorka siliga ee hadda wax soo saarka ee inverter, oo si buuxda u tixgeliyo arrimo kala duwan, si loo yareeyo maalgelinta bilowga ah ee saldhigga korantada photovoltaic iyo in la yareeyo khasaaraha khadka ee nidaamka.
Marka la naqshadeynayo oo la dooranayo fiilooyinka, cabbirrada farsamada sida la qiimeeyay awoodda qaadida hadda, korantada, iyo heerkulka fiilada ayaa inta badan la tixgeliyaa. Inta lagu jiro rakibidda, dhexroorka dibadda, radius foorarsiga, ka hortagga dabka, iwm ee fiilada ayaa sidoo kale la tixgeliyaa. Markaad xisaabinayso kharashka, tixgeli qiimaha fiilada.
1. Inverter-ka wax-soo-saarka hadda jira waa inuu ahaadaa mid la jaan qaadaya awoodda hadda ee fiilada
Hadda wax-soo-saarka rogalaha waxaa lagu go'aamiyaa awoodda. Inverter-ka hal-wajiga ah hadda=awood/230, rogaha saddex-waji ee hadda=awood/(400*1.732), iyo qaar rogrogayasha ah ayaa waliba 1.1 jeer lagu rari karaa.
Awoodda qaadida hadda ee fiilada waxaa lagu go'aamiyaa walxaha, dhexroorka fiilada iyo heerkulka. Waxaa jira laba nooc oo fiilooyinka ah: silig naxaas ah iyo silig aluminium ah, kuwaas oo mid kastaa faa'iido leh. Marka loo eego dhinaca badbaadada, waxaa lagu talinayaa in loo isticmaalo fiilada naxaasta ah ee fiilada AC ee wax soo saarka ee rookaha, iyo BVR jilicsan ayaa guud ahaan loo doortaa hal-waji. Silig, dahaarka PVC, naxaas xudunta u ah (jilicsan) fasalka danab siligga dharka waa 300/500V, saddex-waji dooro 450/750 danab (ama 0.6kV / 1kV) fasalka YJV, YJLV irradiated XLPE dahaaran PVC fiilada korantada, xiriirka ka dhexeeya goynta kaari iyo heerkulka, haddii heerkulka deegaanku ka sarreeyo 35 ° C, hadda la oggol yahay waa in la dhimo. qiyaastii 10% 5°C kasta oo kor u kaca heerkulka; haddii heerkulka deegaanku ka hooseeyo 35°C, heerkulku Marka heerkulku hoos u dhaco 5°C, wakhtiga la ogolyahay waxa lagu kordhin karaa ilaa 10%. Guud ahaan, haddii fiilada lagu rakibo meel hawo leh oo gudaha ah.
2. Cablenaqshad dhaqaale
Meelaha qaar, rogrogaysku wuu ka fog yahay barta isku xirka xadhkaha. Inkasta oo xadhiggu uu buuxin karo shuruudaha awoodda xajinta hadda, khasaaraha khadka ayaa aad u weyn sababtoo ah fiilada dheer. Inta uu bato dagaalku, waxa yaraanaya iska caabbinta gudaha. Laakiin sidoo kale tixgeli qiimaha fiilada, dhexroorka dibadda ee wax soo saarka inverter AC terminal shaabadeeyey.
