ʻO ka laina pahu DC ka laina hoʻouna mai ka ʻōnaehana module photovoltaic i ka inverter ma hope o ka hoʻohuli ʻia ʻana e ka pahu hui.Inā ʻo ka inverter ka puʻuwai o ka ʻōnaehana huina huinaha holoʻokoʻa, a laila ʻo ka ʻōnaehana laina ʻo DC ka aorta.No ka mea, ua hoʻohana ka ʻōnaehana laina kumu DC i kahi hopena ʻaʻole i hoʻopaʻa ʻia, inā he hewa ʻole ke kaula, e ʻoi aku ka nui o ka pōʻino i ka ʻōnaehana a me nā mea hana ma mua o AC.No laila, ʻoi aku ka makaʻala o nā ʻenehana ʻōnaehana PV e pili ana i nā kaula pahu DC ma mua o nā ʻenekini uila ʻē aʻe.
Ke koho ana i ka ponouwea lā DCno ka mea, he mea koʻikoʻi ka ʻōnaehana photovoltaic i hoʻokomo ʻia i kou home a i ʻole ke keʻena i ka hana a me ka palekana.Hoʻolālā ʻia nā kaula lā ikaika e hoʻololi i ka ikehu o ka lā mai kahi ʻāpana o ka ʻōnaehana i kekahi no ka hoʻololi ʻana i ka ikehu uila.Na kāu uea keleawe i kēlā me kēia lā e hana pololei i ka hana a e hoʻopau paha ʻoe i kahi hemahema ʻōnaehana.
ʻO ka loiloi piha ʻana o nā pōʻino like ʻole, manaʻo mākou he 90-95% ka hewa o ke kelepona holoʻokoʻa.ʻEkolu kumu nui o ka hewa ʻāina.ʻO ka mea mua, ʻo nā hemahema o ka hana ʻana i ke kaula he mau huahana kūpono ʻole;ʻO ka lua, ʻo ke kaiapuni hana ʻoʻoleʻa, ʻelemakule kūlohelohe, a pōʻino e nā mana o waho;ʻO ke kolu, ʻaʻole i hoʻonohonoho ʻia ka hoʻonohonoho ʻana a ʻoʻoleʻa ka uwea.
Hoʻokahi wale nō kumu kumu o ka hewa o ka honua--ʻo ka mea hoʻokaʻawale o ke kaula.ʻO ke kaiapuni hana o ka laina kumu DC o nā mea kanu mana photovoltaic he paʻakikī.ʻO nā kahua mana honua nui he wao nahele, ʻāina paʻakai-alkali, me nā ʻokoʻa wela nui i ka lā, a me nā wahi haʻahaʻa loa.No nā kaula i kanu ʻia, ʻoi aku ka kiʻekiʻe o nā koi no ka hoʻopiha ʻana a me ka ʻeli ʻana i nā auwaha kaula;a ʻaʻole ʻoi aku ka maikaʻi o ke kaiapuni hana o nā uwea mana hoʻokaʻawale ma mua o kēlā ma ka honua.E kū nā kaula i nā wela kiʻekiʻe loa, a hiki i ka mahana o ka hale ke hiki i 100-110 ℃.ʻO ke ahi-hōʻoia a me ke ahi-retardant koi o ke kaula, a me ke kiʻekiʻe wela i ka mana nui i ka insulation breakdown voltage o ke kaula.
No laila, ma mua o ka hoʻokomo ʻana a me ka holo ʻana i ka ʻōnaehana, pono ʻoe e hōʻoia i ka nui o ke kaula lā i hoʻokomo ʻia e like me ka manawa a me ka volta o ka ʻōnaehana.Eia kekahi mau hiʻohiʻona, pono e nānā ʻia ma mua o ka hoʻohuli ʻana i ka ʻōnaehana;
1. E hōʻoia i ka like a i ʻole ka nui o ka volta helu o ka pv dc cable ma mua o ka volta helu o ka ʻōnaehana.
2. E hōʻoia i ka like a i ʻole ka nui o ka hiki ke lawe i kēia manawa o ke kaula lā ma mua o ka hiki o ka ʻōnaehana.
3. E hōʻoia i ka mānoanoa o nā kaula a me ka pale pono e kū i nā kūlana kaiapuni ma kou wahi.
4. E nānā i ka hāʻuleʻana o ka volta e hōʻoia i ka palekana.(ʻAʻole pono ka hāʻule o ka voltage ma mua o 2%.)
5. Pono e ʻoi aku ka nui o ka voltage kūpaʻa o ke kelepona DC photovoltaic ma mua o ka volta kiʻekiʻe o ka ʻōnaehana.
Eia kekahi, pono e noʻonoʻo i ka koho a me ka hoʻolālā ʻana o nā kaula kumu PV DC no nā kikowaena mana photovoltaic: ka hana insulation o ke kaula;ʻo ke kūpaʻa ʻana o ka moisture, ke anuanu a me ke anuanu o ke kaula;ka hana wela a me ka lapalapa ahi o ke kaula;ke ʻano o ke kau ʻana o ke kaula;ka mea alakaʻi o ke kaula (Copper core, aluminum alloy core, aluminum core) a me nā kikoʻī ʻāpana o ke kaula.
ʻO ka hapa nui o nā kaula PV DC i waiho ʻia ma waho a pono e pale ʻia mai ka makū, ka lā, ke anu, a me ka ultraviolet.No laila, koho maʻamau nā kaula DC i nā ʻōnaehana photovoltaic i hoʻokaʻawale ʻia i nā kaula kūikawā i hōʻoia ʻia i ka photovoltaic, me ka noʻonoʻo ʻana i ka hopena o nā mea hoʻohui DC a me nā modula photovoltaic.I kēia manawa, ʻo nā kelepona photovoltaic DC i hoʻohana mau ʻia he PV1-F 1*4mm kikoʻī.
ʻO ka mānoanoa o ke kaula lā āu e koho ai no ka ʻōnaehana e pili ana i ka volta o ka ʻōnaehana.ʻO ke kiʻekiʻe o ka volta pūnaewele, ʻoi aku ka lahilahi o ke kaula, no ka mea, e hāʻule ka mana DC.E koho i ka mea hoʻohuli nui e hoʻonui i ka uila ʻōnaehana.
Hiki ke ʻike ʻia ka nalowale o ka volta i loko o kahi ʻōnaehana photovoltaic e like me: nalowale uila = hele i kēia manawa * ka lōʻihi o ke kaula * helu uila.Hiki ke ʻike ʻia ma ke ʻano o ka nalo ʻana o ka volta e like me ka lōʻihi o ke kaula.No laila, pono e hahai ʻia ke kumu o ka array to inverter a me ka inverter i kahi kikoʻī i ka wā e ʻimi ai i ka pūnaewele.Ma keʻano laulā, ʻaʻole e ʻoi aku ka nalowale o ka laina DC ma waena o nā kiʻi kiʻi kiʻi a me ka mea hoʻohuli i ka 5% o ka voltage puka o ka papa, a ʻo ka nalowale o ka laina AC ma waena o ka mea hoʻohuli a me ka helu like ʻaʻole e ʻoi aku ma mua o 2% o ka volta puka o ka mea hoʻohuli.Hiki ke hoʻohana ʻia ke ʻano empirical i ke kaʻina hana ʻenehana:△U=(I*L*2)/(r*S)
Ma waena o lākou △U: hāʻule uila uila -V
I: Pono ke kaula e kū i ke kaula kiʻekiʻe-A
L: Ka lōʻihi o ke kau ʻana i ke kaula -m

ʻO ka lōʻihi o ke kaula kekahi mea nui e noʻonoʻo ai i ke koho ʻana i ke kaula kūpono no ka ʻōnaehana solar.I ka hapanui o nā hihia, ʻoi aku ka lōʻihi o ke kelepona, ʻoi aku ka maikaʻi o ka hoʻouna ʻana i kēia manawa.Akā ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā lula maʻalahi no ka helu ʻana i ka lōʻihi uea i makemake ʻia e pili ana i ka hiki o kēia ʻōnaehana.
I kēia manawa / 3 = ka nui uwea (mm2)
Me ka hoʻohana ʻana i kēia ʻano, hiki iā ʻoe ke loaʻa i ka nui o ke kelepona ʻōnaehana kūpono a me ka pale ʻana i nā pōʻino a i ʻole nā ʻōnaehana hemahema.
ʻO ka papa insulating (sheath) o nā huahana kūpono he palupalu, maʻalahi a maʻalahi, a ʻo ka ʻili o ka ʻili he paʻa, ʻoluʻolu, ʻaʻohe ʻino, a he ʻōlinolino maʻemaʻe.ʻO ka ʻili o ka papa insulating (sheath) pono e akaka a me ka scratch-resistant Mark, nā huahana i hana ʻia me nā mea insulating informal, ʻike ʻia ka ʻāpana insulating i akaka, brittle, a ʻaʻole paʻakikī.
E hōʻailona ʻia nā kaula maʻamau me nā kaula photovoltaic.E kaha i nā kaula kūikawā no nā photovoltaics, a ua kaha ʻia nā ʻili o waho o nā kaula me PV1-F1*4mm.
Loaʻa ka ʻikepili maʻemaʻe i ka pae ʻāina ma ka wahi ʻoi loa o ka ʻano like ʻole o ka papa insulation uea a me ka mānoanoa awelika.ʻO ka mānoanoa o ka insulation uea maʻamau he ʻano like, ʻaʻole eccentric, a paʻa paʻa i ka conductor.
He uea kumu ia i hana ʻia mai nā mea keleawe maʻemaʻe a hoʻopaʻa ʻia i ke kaha kiʻi uea, annealing (hoʻomaʻamaʻa), a me ka stranding.ʻO kona ʻili he ʻōlinolino, ʻoluʻolu, ʻaʻohe burrs, a ʻo ka paʻa paʻa ʻana he palahalaha, palupalu a paʻakikī, ʻaʻole maʻalahi ke haki.ʻO ke kumu uwea maʻamau he uea keleawe ʻulaʻula.ʻO ke kumu o ke kelepona photovoltaic he kālā, a ʻo ka ʻāpana keʻa o ke kumu he uea keleawe poni.
Alohilohi ka conductor, a ua kūpono ka nui o ka conductor i nā koi maʻamau.ʻO nā huahana uea a me nā kaula e hoʻokō i nā koi o ka maʻamau, inā he alumini a keleawe paha, he ʻano māmā a me ka ʻole o ka aila, no laila ke kū nei ke kūpaʻa DC o ka conductor i ke kūlana, he conductivity maikaʻi a me ka hana kiʻekiʻe.
Pono ka palapala hōʻoia huahana maʻamau e hōʻike i ka inoa o ka mea hana, helu wahi, kelepona lawelawe ma hope o ke kūʻai aku, ke kumu hoʻohālike, ka hoʻolālā kikoʻī, ka ʻāpana nominal (maʻamau 2.5 square, 4 square wire, etc.), helu volta (hoʻokahi-core wire 450 / 750V. , ʻelua-core sheath sheath cable 300/500V), ka lōʻihi (ʻo ke kūlana aupuni stipulate ʻo ka lōʻihi he 100M±0.5M), helu limahana nānā, lā hana, a me ka helu maʻamau o ka huahana a i ʻole ka hōʻailona hōʻoia.ʻO ka mea nui, ʻo ke kumu hoʻohālike o ka uea palaki keleawe kumu hoʻokahi i kaha ʻia ma ka huahana maʻamau ʻo 227 IEC01 (BV), ʻaʻole BV.E ʻoluʻolu e hoʻolohe i ka mea kūʻai.
Ma ke ʻano he huahana e pili ana i ka poʻe a me ka waiwai, ua helu mau ʻia nā kelepona ma ke ʻano o ka nānā ʻana a me ka nānā ʻana o ke aupuni.ʻO nā mea hana maʻamau e nānā ʻia e ka ʻoihana kiaʻi i kēlā me kēia manawa.No laila, hiki i ka mea kūʻai aku ke hāʻawi i ka hōʻike nānā o ka ʻoihana nānā maikaʻi, inā ʻaʻole, ʻaʻohe kumu o ka maikaʻi o ka uea a me nā huahana kelepona.
Eia kekahi, no ka hoʻoholo inā he kaula pale ahi a me ke kaula irradiated, ʻoi aku ka maikaʻi o ke ʻoki ʻana i kahi ʻāpana a hoʻā.Inā ʻā a ʻā koke ia, ʻaʻole ia he uwea pale ahi.Inā lōʻihi ka manawa e ʻā ai, i ka wā e haʻalele ai i ke kumu ahi, e pio ia iā ia iho, ʻaʻohe mea ʻala, e hōʻike ana he uwea pale ahi ia (ʻaʻole hiki ke hoʻomālamalama ʻia ke kaula ahi, paʻakikī. e puhi).Ke wela ia no ka manawa lōʻihi, e loaʻa i ke kaula irradiated kahi leo popping liʻiliʻi, ʻoiai ʻaʻole ʻo ke kaula unrradiated.Inā lōʻihi ka wela, e hāʻule nui ka ʻili o ka insulating sheath, a ʻaʻole i piʻi nui ke anawaena, e hōʻike ana ʻaʻole i hoʻokō ʻia ka lāʻau lapaʻau cross-linking.
A hoʻokomo i ke kaula i loko o ka wai wela 90 degere, ʻaʻole e hāʻule koke ke kūpaʻa insulation o ke kaula irradiated maoli ma lalo o nā kūlana maʻamau, a e noho ma luna o 0.1 megohm/km.Inā hāʻule koke ke kū'ē a haʻahaʻa paha ma mua o 0.009 megohm i kēlā me kēia kilomika, ʻaʻole i hoʻopili ʻia ke kaula a hoʻomālamalama ʻia.
ʻO ka mea hope loa, pono e noʻonoʻo ʻia ka hopena o ka mahana ma ka hana o nā uwea dc photovoltaic.ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka haʻahaʻa o ka hiki ke lawe i kēia manawa o ke kaula.Pono e hoʻokomo ʻia ke kaula i kahi wahi e hiki ai.
