He aha ke ʻano o nā kaula PV DC?

Mai ka hānau ʻana o ka photovoltaic solar (PV) ʻoihana, ua ʻike ʻia nā ʻano ʻōnaehana PV like ʻole a me nā kaula PV DC ma ka mākeke.

Eia naʻe, i mua o ia ʻano ākea o nā ʻōnaehana PV like ʻole a me nā ʻāpana like ʻole, ua hoʻomohala nā mea hana kelepona i nā ʻano like ʻole nā kaula PV like ʻole i mea e hiki ai i ka hoʻohui kino o kēia mau mea PV.

Ua kapa ʻia kekahi ʻano uwea PV DC cable, akā i kēia manawa, he nui wale ka poe i maopopo ole i keia ano uwea, ʻO ka mea hoʻoponopono uea ZMS ma hope e lawe iā ʻoe e ʻike iā ia!

Photovoltaic Chiki

ʻIke ʻia ʻo Photovoltaic cable ma ke ʻano he kaula kūikawā no ka photovoltaic, hoʻohana nui ʻia i nā kikowaena mana photovoltaic.

Loaʻa i ke kaula nā mea maikaʻi o ke kūpaʻa wela kiʻekiʻe, pale anu, pale ʻaila, ʻakika a me ke kūpaʻa alkali, Pale UV, pale ahi a me ka pale kaiapuni, a me ke ola lawelawe lōʻihi.

Hiki ke hoʻohana ʻia i nā kūlana climatic koʻikoʻi a ʻo nā hiʻohiʻona maʻamau ʻo PV1-F, H1Z2Z2-K.

Nā ʻano o Pphotovoltaic Chiki

Aia nā kaula PV DC, PV AC uwea, a me nā kaula kūikawā no ka PV lā.

Hoʻoholo ʻia kēia e ka ʻōnaehana a me ke kumu o ke kaula PV, a me ke kaiapuni i hoohana ia ai.

PV DC Uea

PV DC uwea, ʻike ʻia ʻo DC PV uwea, he mau uwea i hoʻohana ʻia e hoʻomaloʻo-hoʻohui i nā panela ʻōnaehana solar PV. He ʻōnaehana photovoltaic a i ʻole panel solar he ʻōnaehana hana uila e hoʻomoʻa i ka lā a hoʻololi i ka ikehu māmā i uila. Hana ʻia ka uila ma ka panel, a koi ʻia ka uwea e hoʻihoʻi i ka uila i ka wahi hōʻiliʻili a mea hana paha.

ʻO ke kaula PV DC kahi ʻano uwea kikoʻī i hoʻonohonoho ʻia no ke kaiapuni PV.

I ka ʻoihana hoʻoili mana, Hoʻokaʻawale ʻia ka hoʻoili ʻana i ka mana i loko o ke au ʻokoʻa (AC) a me ke au pololei (DC).

ʻOi aku ka nui o nā poho uila i ka mana AC i ke kaʻina hoʻoili.

ʻOiai ua hoʻolaha pololei ʻia ka mana DC i ka wā o ka hoʻoili mana. He liʻiliʻi ka nui o ka poho, a nui loa ke au, ʻoi aku ka wikiwiki, a ʻoi aku ka maikaʻi o ka ikehu.

Nā palena ʻenehana o nā uwea DC photovoltaic

Ma ʻEulopa, ʻO ke kelepona kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi., pv1-f kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi DC.

Ka nui o ke alakai:0.5mm2 a 10mm2.

Mea alakaʻi: Ke keleawe ʻumeke, keleawe, alumini ʻaʻahu keleawe, aluminika.

ʻO ka hoʻokaʻawale: Iradiated cross-linked polyethylene insulation + iradiated cross-linked polyethylene sheath.

Voltage: DC 1500 V (max).

Nā hiʻohiʻona: Paʻa ka lā, pale wela kiʻekiʻe a haʻahaʻa, pale i ka oxidation, ʻakika a me ke kinoea alkaline, etc.

Loka wela:-40 °C, 70 °C, 90 °C pulu, 105 °C maloʻo, 125 °C.

Ke ʻano hoʻomoe: Alahaka, waiho ʻia, waiho waho, koho hoolewa pololei.

Kapili: Mea alakaʻi hoʻokahi, alakaʻi pālua, (hiki ke hoʻopilikino ʻia me nā ʻāpana like ʻole a me ka helu o nā cores).

Ma ʻEulopa, ʻO ka nui o nā uwea PV DC no nā paneli photovoltaic maʻamau nā mea lawe keleawe ma 3mm2, 2.5mm2, a me 2mm2 nui.

Nui ka nui o na laina kaapuni 2 sq. ft. a i ʻole ka nui a loaʻa nā mea hoʻokele alumini.

Ua helu ʻia ma 1.5kV, ʻO ka laina PV 1kV a me 1.5kV kūkulu hale hele-ma loko o ka mānoanoa insulation like.

1.5ʻO nā kaula kV PV DC ka hana maʻamau no nā ʻōnaehana e koi ana i nā helu kelepona ma luna o 600V.

ʻO nā pono o nā kaula PV DC

1. Hoʻohana ʻia nā ʻōnaehana PV Solar i nā wela kiʻekiʻe a ʻike ʻia i nā ʻano kūlana kaiapuni.

Ma hope o ka manawa lōʻihi, Ua kaupalena ka poʻe i ka hoʻohana ʻana i nā kaula PV DC no ka hoʻouna ʻana i nā kaula no nā mahiʻai PV like ʻole.

Pono kēia mau kaula PV DC e hoʻokō i ka pale ʻana o ka lā a me ka mahana e koi ʻia e ke kaiapuni.

2. Hoʻonohonoho ʻia nā kaula PV DC no ka hoʻohana ʻana i nā lako PV, ʻoiai ke hana mau ʻia nei kekahi mau ʻano hana PV no nā noi komo komo o lalo.

Loaʻa i kēia mau ʻano uwea ka insulation cross-linked irradiated a kū i ka lā a i ʻole ke kanu pololei ʻana.

3. ʻOkoʻa nā uwea Photovoltaic DC mai nā kaula ʻē aʻe e pili ana i ka mānoanoa insulation, helu uila, a me ka wela hana.

Loaʻa i nā kaula PV DC ka insulation ʻoi aku ka mānoanoa a kūpono no ka hoʻomaloʻo ʻana e kū i nā ʻano ʻano ʻino..

ʻOiai ua helu ʻia nā kaula ʻē aʻe a hiki i 600 V, Ua helu ʻia nā uwea PV DC ma 1500 V no nā kaula DC.

4. Loaʻa i nā ʻano uea ʻē aʻe ke kiʻekiʻe o ka mahana hana uwea o 90° C, ʻoiai hiki i nā kaula PV DC ke kū i nā wela kiʻekiʻe.
5. ʻO nā kaula PV DC kekahi o nā ʻano conductor hoʻokahi me ka volta helu ʻoi aku ma mua o 600V hiki ke hoʻohana ʻia no ke kanu pololei ʻana me ka ʻole o nā pale..

Hoʻomoe a me ka hoʻokele ʻana o PV DC

Hoʻopili pinepine ʻia nā modula PV me nā conductors hoʻokahi a me nā plug-hoʻohui wikiwiki no ka hoʻonohonoho maʻalahi o ke kahua.

Eia naʻe, hiki ke paʻakikī ka hoʻokele ʻana i nā hoʻonohonoho uea ma nā wahi paʻa ʻole a i ʻole nā ​​​​rodents i pilikia.

Pono nā mea hoʻokomo e hōʻoia i ka hoʻopaʻa ʻia ʻana o nā uea a hoʻopaʻa ʻia i kahi e hōʻemi ai i ka abrasion o ka papa waho o ke kaula.. A hoʻohana maʻamau nā mea hoʻokomo i nā kiʻi uea i hiki ke hoʻopaʻa i ke kaula PV i ke kiʻi module.

ʻO kekahi mea hoʻonā i hoʻohana ʻia ma kēia wahi ʻo nā kaula pale-lā i hoʻohana ʻia no ka hoʻopaʻa ʻana i nā kaula PV.

No ka mea, ua ʻae ʻia ʻo PV no ka hoʻohana ʻana i nā pā kahi i pilikia ai nā rodents a i ʻole kahi hiki ke kanu pololei ʻia nā kaula., Hiki ke hoʻopili ʻia nā pā uea i ka ʻaoʻao ma lalo o nā ʻāpana lā ma luna o ka honua.

Pono paha nā code kūloko a ʻoihana paha i ke kākoʻo a me nā ʻano pale.

Ka hopena

Pono e waiho ʻia nā kaula PV DC ma waho i nā kūlana kaiapuni koʻikoʻi a pono e hoʻokumu ʻia nā mea kelepona ma ke kūʻē ʻana i ke kukui UV., ozone, hoʻololi wela nui, a me ka hoʻouka kemika.

ʻO ka hoʻohana lōʻihi ʻana i nā uwea PV maʻamau i loko o ia mau kaiapuni hiki ke lilo i ka hulu uwea e lilo i palupalu a hoʻoheheʻe i ka hoʻokuʻu uwea. E hoʻopōʻino pono kēia mau kūlana i ka ʻōnaehana kelepona, a i ka manawa like e hoʻonui ai i ka pilikia o ke kaula e ʻike i kahi o ke alanui. I ka manawa waena a me ka lōʻihi, ʻano kiʻekiʻe nō hoʻi ka hiki ʻana o ke ahi a i ʻole nā ​​ʻeha i hana ʻia e ke kanaka. Hoʻopilikia nui i ke ola lawelawe o ka ʻōnaehana.

No laila, ʻaʻole pono ka hoʻohana ʻana i nā kaula photovoltaic a me nā ʻāpana i nā mea kanu mana photovoltaic.

Me ka hoʻomau mau ʻana o ka ʻoihana photovoltaic, Ua hoʻokumu mālie ka mākeke modul photovoltaic.

Hiki i nā ʻōnaehana mana Photovoltaic DC ma ka nānā ʻana i nā palena ʻenehana kiʻekiʻe ke lanakila i nā manawa hoʻohana like ʻole. No ka hana ʻana i kahi ʻano o ka hoʻohana ʻana i ka ikehu-emi ka mana hoʻoili mana.

E like me ka ikaika o ka hana o ka mana o ka lā e hōʻemi i ka poho.

Hāʻawi ka ʻōnaehana uila photovoltaic solar i ke kahe mau o ka uila.

ʻO ka hana kūikawā o nā kelepona photovoltaic DC e ho'ēmi i ka paʻakikī o ka mālamaʻana a me ka mālamaʻana i kēlā me kēia lā. No laila, ʻO ke kelepona kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi.
