Mabapi le moralo oa tsamaiso, tšebeliso ea likarolo tse phahameng tsa matla le ho lumellana ho feteletseng ho ka fokotsa litšenyehelo tsa pele tsa lichelete le litšenyehelo ka kilowatt-hora ea tsamaiso.
Litsenyehelo tsa lithapo tsa AC le DC tsamaisong li nka karolo e kholo.Moralo le khetho li lokela ho fokotsoa joang ho fokotsa litšenyehelo?
Khetho ea lithapo tsa DC
Lithapo tsa DC li kenngoa ka ntle.Ka kakaretso ho kgothaletswa ho khetha lisebelisoa tse khethehileng tsa photovoltaic tse nang le mahlaseli le li-cross-linked.
Kamora mabone a matla a elektronike a matla a phahameng, sebopeho sa limolek'hule tsa lesela la ho kenya letsoho la thapo le fetoha ho tloha ho mela ho ea ho sebopeho sa limolek'hule tsa mahlakore a mararo, 'me boemo ba ho hanyetsa mocheso bo eketseha ho tloha ho 70 ℃ ho isa ho 90 ℃, 105 ℃ , 125 ℃, 135 ℃, esita le 150 ℃, e leng 15-50% e phahameng ho feta matla a hona joale a ho jara a likhoele tsa litlhaloso tse tšoanang.
E khona ho mamella liphetoho tse matla tsa mocheso le khoholeho ea lik'hemik'hale 'me e ka sebelisoa ka ntle ka lilemo tse fetang 25.
Ha u khetha lithapo tsa DC, u hloka ho khetha lihlahisoa tse nang le litifikeiti tse nepahetseng ho tsoa ho baetsi ba kamehla ho netefatsa ts'ebeliso ea nako e telele ea kantle.
Mohala o sebelisoang haholo oa photovoltaic DC ke PV1-F 1*4 4 square cable.Leha ho le joalo, ka keketseho ea motlakase oa motlakase oa photovoltaic le ho eketseha ha motlakase o le mong oa motlakase, bolelele ba cable ea DC bo ntse bo eketseha, 'me tšebeliso ea 6 square DC cable e ntse e eketseha.
Ho ea ka litlhaloso tse nepahetseng, ka kakaretso ho khothalletsoa hore tahlehelo ea photovoltaic DC e se ke ea feta 2%.Re sebelisa mokhoa ona ho rala mokhoa oa ho khetha thapo ea DC.
Ho hanyetsa mohala oa PV1-F 1 * 4mm2 DC cable ke 4.6mΩ / mitha, 'me ho hanyetsa mohala oa PV 6mm2 DC cable ke 3.1mΩ/mitha.Ho nka hore motlakase o sebetsang oa mochine oa DC ke 600V, tahlehelo ea ho theoha ha motlakase ea 2% ke 12V.
Ho nka hore mochine oa hona joale ke 13A, o sebelisa 4mm2 DC cable, sebaka se tsoang pheletsong e hōle ka ho fetisisa ea mochine ho ea ho inverter e khothalletsoa hore e se ke ea feta limithara tse 120 (khoele e le 'ngoe, ntle le lipalo tse ntle le tse mpe).
Haeba e le kholo ho feta sebaka sena, ho kgothaletswa hore o kgethe thapo ea 6mm2 DC, empa ho kgothaletswa hore sebaka se hole ho tloha pheletsong e hole ya mojule ho ya ho inverter ha se feta 170 metres.
Khetho ea likhoele tsa AC
E le ho fokotsa litšenyehelo tsa tsamaiso, likarolo le li-inverters tsa liteishene tsa matla a photovoltaic ha li tloaelehe ho etsoa ka karolelano ea 1: 1.Ho e-na le hoo, palo e itseng ea ho lumellana ho feta tekano e etselitsoe ho latela maemo a mabone, litlhoko tsa morero, joalo-joalo.
Mohlala, bakeng sa karolo ea 110KW, ho khethoa inverter ea 100KW.Ho latela lipalo tse fetang makhetlo a 1.1 ka lehlakoreng la AC la inverter, boholo ba tlhahiso ea AC hajoale e ka ba 158A.
Khetho ea likhoele tsa AC e ka khethoa ho latela boholo ba tlhahiso ea hona joale ea inverter.Hobane ho sa tsotelehe hore na likarolo li bapisitsoe ho feta bokae, hona joale ho kenyelletsoa ha inverter AC ho ke ke ha hlola ho feta tekanyo e phahameng ea tlhahiso ea motlakase ea motlakase.
Ka tloaelo ho sebelisoa photovoltaic tsamaiso ea likhoele tsa koporo tsa AC li kenyelletsa BVR le YJV le mefuta e meng.BVR e bolela koporo ea mantlha ea polyvinyl chloride e insulated terata e bonolo, YJV cross-linked polyethylene insulated power cable.
Ha u khetha, ela hloko boemo ba voltage le boemo ba mocheso oa cable.Khetha mofuta o thibelang malakabe.Litlhaloso tsa lithapo li hlahisoa ka nomoro ea mantlha, karolo ea "cross-section" le "voltage level": polelo e hlalosang mohala oa lekala e le 'ngoe, 1 * karolo e fapaneng ea lebitso, joalo ka: 1 * 25mm 0.6 / 1kV, e bonts'ang mohala oa lisekoere tse 25.
Litlhaloso tsa likhoele tsa makala tse sothehileng tse nang le mefuta e mengata: palo ea likhoele tse ka har'a loop e le 'ngoe * ka lebitso la sefapano, joalo ka: 3*50+2*25mm 0.6/1KV, e bonts'ang lithapo tse phelang tse lisekoere tse 3 50, terata e sa nke lehlakore ea lisekoere tse 25 le terata ea 25 square ground terata.
Phapano ke efe lipakeng tsa thapo e le 'ngoe ea mantlha le ea li-multi-core?
Cable e nang le "single-core" e bolela thapo e nang le conductor e le 'ngoe feela sebakeng sa insulation.Multi-core cable e bolela thapo e nang le li-cores tse fetang bonngoe.Mabapi le ts'ebetso ea ho kenya letsoho, likhoele tse peli tsa mantlha le tse ngata li tlameha ho fihlela maemo a naha.
Phapang pakeng tsa li-multi-core cable le single-core cable ke hore mohala o le mong oa motheo o thehiloe ka ho toba lipheletsong tse peli, 'me lera le sireletsang tšepe la mohala le ka boela la hlahisa hona joale ho potoloha, ho fella ka tahlehelo;

Ho ea ka pono ea matla a potoloho, bakeng sa lithapo tse le 'ngoe le tse ngata-ngata, matla a hona joale a ho jara a lithapo tsa motlakase a le mong a kholo ho feta a lithapo tse tharo-kholo bakeng sa karolo e tšoanang ea sefapano;
Ts'ebetso ea ho felisa mocheso oa likhoele tse nang le li-single-core e kholo ho feta ea lithapo tse ngata.Tlas'a mojaro o tšoanang kapa maemo a khutšoanyane a potoloho, mocheso o hlahisoang ke lithapo tse nang le lisebelisoa tse le 'ngoe o fokotsehile ho feta oa lithapo tse ngata, tse sireletsehileng haholoanyane;
Ho ea ka pono ea ho beha lithapo, lithapo tse nang le lithapo tse ngata li bonolo ho beha, 'me likhoele tse nang le ts'ireletso ea lera le ka hare le tse ngata li bolokehile ho feta;Lithapo tsa mantlha li bonolo ho kobeha ha li beoa, empa bothata ba ho beha sebaka se selelele bo boholo bakeng sa likhoele tsa mantlha ho feta lithapo tse nang le li-multi-core.
Ho ea ka pono ea ho kenya hlooho ea mohala, lihlooho tsa li-cable-core li bonolo ho li kenya le tse loketseng ho arola line.Mabapi le theko, theko ea yuniti ea likhoele tse ngata-ngata e phahame hanyenyane ho feta ea lithapo tsa li-single-core.
Bokhoni ba ho kopanya tsamaiso ea photovoltaic
Mehala ea tsamaiso ea photovoltaic e arotsoe ka likarolo tsa DC le AC.Likarolo tsena tse peli li hloka ho kopanngoa ka likhoele ka thoko.Karolo ea DC e hokahane le likarolo, 'me karolo ea AC e hokahane le marang-rang a matla.
Ho na le lithapo tse ngata tsa DC liteisheneng tsa motlakase tse mahareng le tse kholo.E le ho nolofatsa tlhokomelo ea nako e tlang, linomoro tsa mohala oa cable ka 'ngoe li lokela ho khomarela ka thata.Lithapo tsa motlakase tse matla le tse fokolang lia aroloa.Haeba ho na le mehala ea matšoao, joalo ka likhokahano tse 485, li lokela ho tsamaisoa ka thoko ho qoba tšitiso.
Ha u tsamaisa lithapo, lokisa likotopo le marokho.Leka ho se pepese lithapo.Ho tla shebahala ho le betere haeba lithapo li tsamaisitsoe ka holimo le ka holimo.Leka ho se be le likhoele tsa likhoele likotopong le marokhong hobane ha ho bonolo ho li hlokomela.Haeba lithapo tsa aluminium li nka sebaka sa lithapo tsa koporo, li-adapter tse tšepahalang tsa koporo-aluminium li tlameha ho sebelisoa.
Tsamaisong eohle ea photovoltaic, lithapo ke karolo ea bohlokoa haholo, 'me karolo ea bona ea litšenyehelo tsamaisong e ntse e eketseha.Ha re rala seteishene sa motlakase, re hloka ho boloka litšenyehelo tsa sistimi ka hohle kamoo ho ka khonehang ha re ntse re netefatsa ts'ebetso e tšepahalang ea seteishene sa motlakase.
Ka hona, moralo le khetho ea likhoele tsa AC le DC bakeng sa litsamaiso tsa photovoltaic li bohlokoa haholo.
Ka kopo, ikutloe u lokolohile ho ikopanya le rona bakeng sa lintlha tse ling mabapi le lithapo tsa letsatsi.
