U ka khetha lithapo tsa Solar DC joang bakeng sa limela tsa matla a letsatsi?

Ho tsoa ho lisebelisoa tsa cable conductor:

Maemong a mangata, lithapo tsa DC tse sebelisoang liteisheneng tsa matla a letsatsi li sebelisetsoa mosebetsi oa ka ntle oa nako e telele.Ka lebaka la moeli oa maemo a kaho, lihokelo li sebelisoa haholo bakeng sa khokahano ea cable.Lisebelisoa tsa li-cable conductor li ka aroloa ka mokokotlo oa koporo le motheo oa aluminium.Copper core cable e na lekhanyetso e ntle ea oxidation ho feta aluminium, bophelo bo bolelele, botsitso bo botle, ho theoha ha motlakase o tlaseletahlehelo ea matla a tlase;kahong, hobane mokokotlo oa koporo o fetoha le maemo 'me radius e lumelletsoeng ea ho kobeha e nyane, ho bonolo ho reteleha le ho feta phala;'me mokokotlo oa koporo o hanyetsana le mokhathala le ho khumama khafetsa ha ho bonolo ho senya, kahoo wiring e loketse;ka nako e ts'oanang, mokokotlo oa koporo o na le matla a phahameng a mochine 'me o khona ho mamella tsitsipano e kholo ea mochine, e leng se tlisang boiketlo bo boholo ba ho haha le ho beha,' me se etsa hore ho be le maemo bakeng sa kaho ea mechine.Ho fapana le hoo, likhoele tsa mantlha tsa aluminium lie sekametseng ho oxidation(electrochemical reaction) manonyeletsong a ho kenya ka lebaka la thepa ea lik'hemik'hale ea lisebelisoa tsa aluminium, haholo-holo lintho tse etsahalang, tse ka lebisang habonolo.mefokolo.

Ka hona, likhoele tsa koporo li na le melemo e ikhethang ts'ebelisong ea liteishene tsa matla a letsatsi, haholo-holo tšimong ea phepelo ea motlakase e patiloeng ka kotloloho.E ka fokotsa sekhahla sa kotsi, ea ntlafatsa ts'epo ea phepelo ea motlakase, 'me e loketse bakeng sa kaho, ts'ebetso le tlhokomelo.Lena ke lona lebaka leo ka lona likhoele tsa koporo li sebelisoang haholo phepelong ea motlakase e ka tlas'a lefatše Chaena.

Phapano ke efe lipakeng tsa lithapo tsa Normal DC le lithapo tsa Solar DC?

Ho ea ka pono ea thepa ea sheath ea cable insulation:

Nakong ea ho kenya le ho sebetsa le ho hlokomela liteishene tsa matla a letsatsi, lithapo li ka ’na tsa tsamaisoa mobung o ka tlas’a lefatše, tsa tlala lehola le mafika, lintlheng tse bohale tsa mohaho oa marulelo, ’me li pepesehetse moea.Lithapo li ka ba le matla a fapaneng a kantle.Haeba sheath ea cable e se matla ka ho lekaneng,lera la insulation la cable le tla senyeha, le tla ama bophelo ba ts'ebeletso ea mohala kaofela, kapa sesosae khuts'oane, mollo, lelikotsi tsa motho ka mong.Patlisiso ea mahlale a lithapo le basebetsi ba tekheniki ba fumane hore thepa e hokahaneng le radiation e na le matla a holimo ho feta pele ho kalafo ea radiation.Ts'ebetso ea ho hokahanya e fetola sebopeho sa lik'hemik'hale tsa polymer ea thepa ea sheath ea cable, thepa ea fusible thermoplastic e fetoloa hore e be lisebelisoa tse sa fusible elastomeric, 'me mahlaseli a marang-rang a ntlafatsa haholo thepa ea mocheso, mochini le motlakase oa thapo. thepa ea ho itšireletsa.Lintho tsa lik'hemik'hale.

Hangata loop ea DC e angoa ke lintlha tse sa tšoaneng tse sa thabiseng nakong ea ts'ebetso, e leng se etsang hore ho be le motheo, ho etsa hore tsamaiso e se ke ea sebetsa ka mokhoa o tloaelehileng.Joalo ka extrusion, tlhahiso e mpe ea li-cable, lisebelisoa tse sa tšoaneleheng tsa ho koala, ts'ebetso e tlase ea insulation, botsofali ba sistimi ea DC e kenang, kapa mefokolo e itseng e ka bakang ho theoa kapa ho ba kotsi ea motheo.

Ho latela pono ea ho hanyetsa boima ba mochini:

Bakeng sa lithapo tsa solar dc, nakong ea ho kenya le ho sebelisoa, lithapo li ka tsamaisoa lintlheng tse bohale tsa mohaho oa marulelo.Ka nako e ts'oanang, likhoele li tlameha ho mamellakhatello, kobeha, tsitsipano, meroalo e tsitsinyehanglekhanyetso e matla ea tšusumetso, e phahametseng likhoele tse tloaelehileng tsa dc.Haeba u sebelisa likhoele tse tloaelehileng tsa dc, sheath e na lets'ebetso e mpe ea ts'ireletso ea UV, e leng se tla etsa hore sekhahla sa ka ntle sa mohala se tsofala, se tla ama bophelo ba tšebeletso ea mohala, e leng se ka lebisang ho ponahalo ea lipotoloho tse khutšoanyane, lialamo tsa mollo le likotsi tse kotsi ho basebetsi.

Ka mor'a ho khantša mahlaseli, sheath ea mocheso oa motlakase oa letsatsi oa dc o na le thepa ea ho hanyetsa mocheso o phahameng, ho hanyetsa mahlaseli a ultraviolet, ho hanyetsa oli le ho hanyetsa serame.Bophelo ba ts'ebeletso bo feta lilemo tse 25, tse ke keng tsa bapisoa le likhoele tse tloaelehileng tsa dc.
