Lenaneong la photovoltaic, mocheso oa ACthapoe boetse e fapane ka lebaka la libaka tse fapaneng tseo mela e kentsoeng ho tsona.Sebaka se pakeng tsa inverter le sebaka sa marang-rang sa marang-rang se fapane, se fella ka ho theoha ho fapaneng ha motlakase ho cable.Ka bobeli mocheso le ho theoha ha motlakase ho tla ama tahlehelo ea sistimi.Ka hona, hoa hlokahala ho rala ka mokhoa o utloahalang bophara ba terata ea tlhahiso ea hona joale ea inverter, 'me u nahane ka ho pharaletseng lintlha tse sa tšoaneng, e le ho fokotsa letsete la pele la seteishene sa motlakase sa photovoltaic le ho fokotsa tahlehelo ea mohala oa tsamaiso.
Ha o rala le ho khetha likhoele, ho nahanoa haholo ka litekanyetso tsa tekheniki tse kang matla a ho jara a hajoale, voltage le mocheso oa thapo.Nakong ea ho kenya, bophara ba ka ntle, radius e kobehang, thibelo ea mollo, joalo-joalo ea cable e boetse e nkoa.Ha u bala litšenyehelo, nahana ka theko ea mohala.
1. Phallo ea motlakase ea motlakase e lokela ho lumellana le matla a hona joale a ho jara a cable
Phallo ea hona joale ea inverter e khethoa ke matla.Mokhahlelo o le mong inverter current = matla / 230, inverter ea mekhahlelo e meraro ea hona joale = matla / (400 * 1.732), 'me li-inverters tse ling li ka boela tsa imeloa ka makhetlo a 1.1.
Bokhoni ba hona joale ba thapo bo khethoa ke thepa, bophara ba terata le mocheso.Ho na le mefuta e 'meli ea likhoele: terata ea koporo le terata ea aluminium, e' ngoe le e 'ngoe ea tsona e le molemo.Ho latela pono ea polokeho, ho khothaletsoa ho sebelisa terata ea koporo bakeng sa thapo ea AC ea inverter, 'me terata e bonolo ea BVR hangata e khethoa bakeng sa mohato o le mong.terata, PVC insulation, koporo core (bonolo) lesela terata voltage sehlopha ke 300/500V, mekhahlelo e meraro khetha 450/750 voltage (kapa 0.6kV/1kV) sehlopha YJV, YJLV irradiated XLPE insulated PVC Sheathed thapo ea matla, kamano pakeng tsa ho fokotseha ha conductor le mocheso, haeba mocheso o potolohileng o phahametse 35 ° C, hona joale ho lumelloa ho lokela ho fokotsoa ka hoo e ka bang 10% bakeng sa keketseho e 'ngoe le e 'ngoe ea 5 ° C mocheso;haeba mocheso oa tikoloho o ka tlase ho 35 ° C, mocheso Ha mocheso o theoha ka 5 ° C, hona joale ho lumelloa ho ka eketsoa ka hoo e ka bang 10%.Ka kakaretso, haeba thapo e kenngoa sebakeng se nang le moea o kenang ka tlung.

Libakeng tse ling, inverter e hole haholo le ntlha ea khokahanyo ea marang-rang.Le hoja mohala o ka finyella litlhoko tsa matla a hona joale a ho jara, tahlehelo ea mohala e batla e le khōlō ka lebaka la mohala o molelele.Ha e le kholoanyane warp, e fokotseha khanyetso ea ka hare.Empa hape nahana ka theko ea thapo, bophara bo ka ntle ba inverter AC output tiisitsoe terminals.
