Posong ea rona e fetileng, re file babali tataiso e sebetsang ea liphanele tsa letsatsi tsa lapeng.Mona re tla ntšetsa pele sehlooho sena ka ho u fa tataiso e arohaneng ea lithapo tsa letsatsi.
Lithapo tsa letsatsi, joalo ka ha lebitso le bolela, ke likotopo tsa phetiso ea motlakase.Haeba u ncha ho litsamaiso tsa PV, ho bohlokoa ho ithuta lintho tsa motheo.
Tsoela pele ho bala ho ithuta haholoanyane ka mofuta ona oa thapo, ho kenyeletsoa hore na li sebetsa joang, li sebelisetsoa eng, le mokhoa oa ho khetha thapo e nepahetseng.
Cable ea letsatsi ka mokhoa oa photovoltaic
Ha feela motlakase o ntse o le teng, ho tlameha ho be le mehala le likhoele.Litsamaiso tsa photovoltaic ha li joalo.
Lithapo le likhoele li phetha karolo ea bohlokoa ho fumana ts'ebetso e ntle ho tsoa litsing tsa motlakase.Tabeng ea litsamaiso tsa photovoltaic, tlhokahalo ea lisebelisoa tsa letsatsi le lisebelisoa tsa boleng bo phahameng e ba tsa bohlokoa haholo.
Lisebelisoa tsa Photovoltaic li na le karolo e le 'ngoe kapa tse ngata tsa letsatsi tse kopantsoeng le li-inverters le lisebelisoa tse ling.E sebelisa matla a letsatsi ho hlahisa motlakase.
E le hore u fumane molemo ka ho fetisisa letsatsing, mochine oa photovoltaic kapa motlakase oa letsatsi o hloka ho sebetsa "e tiile" le ka tatellano.E 'ngoe ea likarolo tsa bohlokoa ke cable ea letsatsi.
Ke eng?
Lithapo tsa letsatsi li etselitsoe ho fetisetsa matla a letsatsi a DC ka lisebelisoa tsa photovoltaic.Li sebelisoa e le likhoele tse hokahanyang bakeng sa liphanele tsa letsatsi le li-photovoltaic arrays ka har'a marang-rang a letsatsi.
Li na le matla a phahameng a mochine 'me li khona ho mamella maemo a leholimo a thata.Mererong ea letsatsi, boholo ba lithapo tsa letsatsi li beoa kantle 'me li pepesehetse mocheso o phahameng.
Nakong ea nako e telele ea bophelo ba lilemo tse ka bang 20 ho isa ho tse 25, li ka tobana le maemo a thata.Ka hona, ho bohlokoa ho hlomella sistimi ea hau ea letsatsi ka lithapo le likhoele tsa boleng bo holimo.
Lithapo tsa letsatsi li arotsoe ho latela palo ea lithapo le litlhaloso tsa tsona.Ho phaella moo, bophara bo boetse bo itšetlehile ka palo ea lithapo le litlhaloso tsa tsona.
Ka kakaretso, ho na le mefuta e meraro ea likhoele tsa letsatsi tse sebelisoang lits'ebetsong tsa photovoltaic:
DC cable ea letsatsi
Solar DC cable e kholo
Mohala oa motlakase oa letsatsi
Mefuta ea cable ea letsatsi
Mererong ea matla a letsatsi, mefuta e fapaneng ea likhoele e hlokahala ho etsa mosebetsi.Ka bobeli lithapo tsa DC le AC li ka sebelisoa.
Phanele ea photovoltaic le inverter, ho kenyeletsoa lebokose la li-junction, li kopantsoe ka mohala oa DC.Ka nako e ts'oanang, inverter le sub-station li kopantsoe ke cable ea AC.
1. Mohala oa letsatsi oa DC
Lithapo tsa letsatsi tsa DC ke likhoele tsa koporo tse nang le konokono e le 'ngoe tse nang le insulation le sheathed.Li sebelisoa ka har'a liphanele tsa letsatsi tsa photovoltaic 'me e ka ba likhoele tsa module kapa likhoele tsa likhoele.
Ho phaella moo, li tla le li-connectors tse loketseng 'me li hahiloe pele ho phanele.Ka hona, u ke ke ua khona ho li fetola.
Maemong a mang, o tla hloka khoele ea likhoele tsa letsatsi tsa DC ho e hokahanya le liphanele tse ling.
2. Mohala o moholo oa letsatsi oa DC
Mohala o moholo oa DC ke mohala o moholo oa pokello ea matla.Ba kopanya lebokose la jenereithara ho lithapo tse ntle le tse mpe tsa inverter e bohareng.
Ho phaella moo, li ka ba lithapo tsa mantlha tse le 'ngoe kapa tse peli.Khoele e le 'ngoe ea mantlha e nang le insulation habeli ke tharollo e sebetsang ea ho fana ka ts'epo e phahameng.Ka nako e ts'oanang, khokahano lipakeng tsa inverter ea letsatsi le lebokose la jenereithara la jenereithara, ts'ebeliso e ntle ka ho fetisisa ea thapo ea DC e habeli.
Ka kakaretso litsebi li khetha ho kenya ka ntle lithapo tse kholo tsa letsatsi tsa DC.Boholo hangata ke 2mm, 4mm le 6mm.
Tlhokomeliso: Ho qoba mathata a joalo ka potoloho e khuts'oane le ho thella fatše, ho khothaletsoa hore lithapo tse nang le polarity tse fapaneng li tsamaiswe ka thoko.
3. Ac cable
Lithapo tsa Ac li hokahanya inverter ea letsatsi ho lisebelisoa tsa ts'ireletso le marang-rang a matla.Bakeng sa litsamaiso tse nyane tsa PV tse nang le li-inverters tsa mekhahlelo e meraro, thapo ea AC ea mantlha e mehlano e sebelisoa ho hokela marang-rang.
Kabo ea lithapo e tjena:
Lithapo tse tharo tse phelang,
Mohala o le mong oa fatše le terata e le 'ngoe e sa jeleng paate.
Keletso: Haeba sistimi ea hau ea PV e na le inverter ea mokhahlelo o le mong, sebelisa thapo ea AC ea likarolo tse tharo.
Bohlokoa ba cable ea letsatsi mererong ea PV
Joalokaha ho boletsoe pejana, lisebelisoa tsa letsatsi li fetisetsa matla a letsatsi a DC ho tloha karolong e 'ngoe ea mochine oa photovoltaic ho ea ho o mong.Tsamaiso e nepahetseng ea cable e bohlokoa ha ho tluoa tabeng ea polokeho le nako e telele ea tsamaiso e 'ngoe le e 'ngoe ea PV.
Ho kenngoa ha lithapo mererong ea letsatsi ho itšetlehile ka mahlaseli a ultraviolet, mocheso o feteletseng le mongobo oa moea.Ba ka mamella litlhoko tse thata tsa tsamaiso ea photovoltaic - ka hare le ka ntle.
Ho phaella moo, lithapo tsena ha li matla feela, empa li boetse li hanyetsa boemo ba leholimo.Ba ka mamella khatello ea maikutlo, ho kobeha kapa ho otlolla, le khatello ea lik'hemik'hale ka mokhoa oa:
Khetha thapo e nepahetseng ea letsatsi bakeng sa sistimi ea hau ea PV
Lithapo tsa letsatsi li lokela ho lekana bakeng sa lits'ebetso tse batloang haholo tsa sistimi ea PV.Khetha mofuta o nang le khanyetso e phahameng ka ho fetesisa ea liqholotso tsa sepakapaka joalo ka UV, ozone le mongobo.
Eseng seo feela, empa thapo e lokela ho khona ho mamella mocheso o matla (-40 ° C ho isa ho 120 ° C).Ho na le moferefere, tšusumetso, ho taboha le khatello.
Mohato o mong hape, mofuta o nepahetseng oa letsatsi
