Pehea e koho ai i nā kelepona Photovoltaic no nā ʻōnaehana Photovoltaic?

Ua piʻi hou ke kumukūʻai o ke keleawe, a ua piʻi pū ke kumukūʻai o nā kaula.I ka huina kumukūʻai o nā ʻōnaehana photovoltaic, ke kumukūʻai o nā mea pono e like meuwea photovoltaica ua ʻoi aku ka nui o nā hoʻololi ma mua o nā mea hoʻohuli, a ʻoi aku ka haʻahaʻa ma mua o nā ʻāpana a me nā kākoʻo.Ke loaʻa iā mākou ke kaha kiʻi o ka hui hoʻolālā a ʻike i nā palena o ke ʻano uea, mānoanoa, kala, a me nā mea ʻē aʻe, hiki iā mākou ke hoʻomaka e kūʻai me ka papa inoa.Eia nō naʻe, nui nā ʻano uea, a nui nā mea hoʻohana i pīhoihoi i nā ʻano uea he nui.ʻO wai ka maikaʻi?

Ke koho ʻana i kahi kaula photovoltaic, pono mākou e nānā mua i ʻelua mau mea: ke alakaʻi a me ka papa insulating.ʻOiai maikaʻi kēia mau ʻāpana ʻelua, ʻike ʻia ka maikaʻi o ka uea i ka hilinaʻi.

1. Ke alakai

Wehe i ka insulation o ke kaula e hōʻike i ka uea keleawe i loko, ʻo ia ke alakaʻi.Hiki iā mākou ke hoʻoholo i ka maikaʻi o nā conductors mai ʻelua mau hiʻohiʻona:

01. kala

ʻOiai ua kapa ʻia nā alakaʻi he "copper", ʻaʻole lākou he 100% keleawe maʻemaʻe, a aia kekahi mau mea haumia i loko o lākou.ʻO ka nui o nā haumia i loko, ʻoi aku ka maikaʻi o ka conductivity o ka conductor.E ʻike ʻia ka nui o nā mea haumia i loko o ka conductor i ke kala.

ʻO ke keleawe maikaʻi maikaʻi loa i kapa ʻia ʻo "copper ʻulaʻula" a i ʻole "copper ʻulaʻula" - e like me ka manaʻo o ka inoa, ʻo ke kala o kēia ʻano keleawe he ʻulaʻula, ʻulaʻula, ʻulaʻula-ʻulaʻula, ʻulaʻula ʻeleʻele.

ʻOi aku ka ʻino o ke keleawe, ʻoi aku ka māmā o ke kala a ʻoi aku ka melemele, i kapa ʻia ʻo "brass."ʻO kekahi keleawe melemele māmā-ua kiʻekiʻe loa ka mea haumia o kēia keleawe.

He keʻokeʻo kekahi o lākou, he mau uwea kūlana kiʻekiʻe kēia.Hoʻopili ʻia nā uea keleawe me kahi papa o ka tin, ʻo ke kumu nui ka pale ʻana i ke keleawe mai ka oxidizing e hana i ka patina.ʻAʻole maikaʻi loa ka conductivity o ka patina, e hoʻonui ai i ka pale a me ka wela.Eia kekahi, hiki i ka tinning copper wires ke pale aku i ka insulation rubber mai ka pipili, blackening a brittleness o ke kumu, a me ka hoʻomaikaʻi ʻana i kona solderability.ʻO nā uwea Photovoltaic DC he mau uea keleawe i hoʻopaʻa ʻia.

02. mānoanoa

Ke like ke anawaena o ka uea, ka manoanoa o ka conductor, ka ikaika o ka conductivity-i ka hoohalike ana i ka mānoanoa, pono wale ke conductor e hoohalike, a me ka mānoanoa o ka insulating papaʻaʻole pono e hoʻohui.

E ho'āʻo e hoʻohana i nā kaula he nui o ka uea maʻalahi.Hoʻokahi wale nō uea koʻikoʻi i loko o ke kaula, i kapa ʻia ʻo ka uea kumu hoʻokahi, e like me BVR-1*6;he nui na uwea kumu i loko o ke kaula, e like me YJV-3*25+1*16, Ua kapaia he uwea multi-core;ua haku ʻia kēlā me kēia uea koʻikoʻi me nā uea keleawe he nui a ua kapa ʻia ʻo ia he uea multi-strand, ʻano palupalu a kūpono i nā ʻōnaehana photovoltaic.Hiki ke hoʻopaʻa pololei ʻia ka uea kaula hoʻokahi ma ka pahu, akā ʻoi aku ka paʻakikī o ka uea hoʻokahi a ʻaʻole kūpono no ka hoʻokomo ʻana i nā wahi me kahi radius huli liʻiliʻi.No nā uea multi-strand ʻoi aku ka liʻiliʻi ma mua o 16 mau mika square, pono e hoʻohana i nā pahu uwea a me nā pliers terminal crimping manual.No nā uea multi-strand ʻoi aku ka nui ma mua o 16 mau mika square, pono ia e hoʻohana i nā pahu kūikawā no nā ʻili hydraulic.

2. Lae Hookui

ʻO ka papa o ka lāʻau ma waho o ka uea, ʻo ia ka ʻāpana insulation o ka uea.ʻO kāna hana ka hoʻokaʻawale ʻana i ka mea hoʻokele ikaika mai ka honua o waho, pale i ka ikehu uila mai ka kahe ʻana i waho, a pale i ka poʻe o waho mai ka hoʻopuʻi uila.ʻO ka maʻamau, hiki ke hoʻohana ʻia nā ʻano ʻekolu e hoʻoholo ai i ka maikaʻi o ka papa insulating:

1) Hoʻopā, hoʻopā māmā i ka ʻili o ka papa insulating me kou mau lima.Inā ʻoʻoleʻa ka ʻili, hōʻike ia i ka maikaʻi ʻole o ke kaʻina hana o ka papa insulating a hiki i nā hewa e like me ka leakage uila.E kaomi i ka papa insulating me kou manamana lima, a inā hiki iā ia ke hoʻihoʻi koke, hōʻike ia he kiʻekiʻe ka mānoanoa a me ka paʻakikī o ka papa insulating.

2) E kūlou, e lawe i kahi ʻāpana uwea, e kulou i hope a i hope i kekahi mau manawa, a laila e hoʻopololei i ke kaula no ka nānā ʻana.Inā ʻaʻohe ʻike ma ka ʻili o ka uea, hōʻike ia he ʻoi aku ka paʻakikī o ka uea.Ina ka ili o ka uea i maopopo indentation a koʻikoʻi whitening, e hōʻoia i ka uea i ilihune toughness.Ua kanu ʻia i loko o ka lepo no ka manawa lōʻihi, maʻalahi ka makahiki, lilo i palupalu, a maʻalahi hoʻi e kahe i ka uila i ka wā e hiki mai ana.

3) Puhi.E hoʻohana i ka māmā e hoʻomau i ka ʻā ʻana ma ka uea a hiki i ka wā e pio ai ke ahi.A laila e hoʻopau i ka māmā a hoʻomaka i ka manawa-inā hiki ke hoʻopau koke ʻia ke kelepona i loko o 5 kekona, e hōʻike ana ia he maikaʻi ke ahi o ka uea.Inā ʻaʻole, ua hōʻoia ʻia ʻaʻole hiki i ka hiki ke pale ʻana i ka lapalapa o ka uea i ka maʻamau, ʻoi aku ka nui o ke kaapuni a i ʻole ka maʻalahi o ke kaʻapuni e hoʻoulu i ke ahi.

3. Mākaukau Uea Pūnaehana Photovoltaic

Hoʻokaʻawale ʻia ka laina o ka ʻōnaehana photovoltaic i kahi ʻāpana DC a me kahi ʻāpana AC.Pono e hoʻokaʻawale ʻia kēia mau ʻāpana ʻelua o ka laina.Hoʻopili ʻia ka ʻāpana DC i nā ʻāpana, a pili ka ʻāpana AC i ka pā.Nui nā uwea DC ma waena a me ka mana nui.I mea e maʻalahi ai ka mālama ʻana i ka wā e hiki mai ana, pono e hoʻopaʻa ʻia nā helu uea o nā kaula.E hoʻokaʻawale i nā uwea ikaika a nāwaliwali.Inā loaʻa nā uwea hōʻailona, ​​e hoʻokaʻawale iā lākou i mea e pale aku ai i ke keakea.Pono e hoʻomākaukau i nā paipu wili a me nā alahaka, e hoʻāʻo ʻaʻole e hōʻike i nā uea, a ʻoi aku ka maikaʻi o nā uea ākea a me ke kūpaʻa i ka wā e holo ai.E ho'āʻo ʻaʻole e loaʻa nā hono uwea i nā paipu wili a me nā alahaka, no ka mea, ʻaʻole kūpono ka mālama ʻana.

Ma nā pūnaewele photovoltaic, nā papahana hale a me nāʻoihanaʻoihana liʻiliʻi a me nāʻoihana kalepa, aia ka mana o ka mea hoʻohuli ma lalo o 20kW, aʻo ka'āpana'āpana o ke kaula hoʻokahi ma lalo o 10 square.Paipai ʻia e hoʻohanauwea lā nui-core.I kēia manawa, ʻaʻole paʻakikī ka waiho ʻana a maʻalahi hoʻi e mālama;ʻO ka mana o ka mea hoʻololi ma waena o 20-60kW, a ʻo ka ʻāpana cross-sectional o kahi kaula hoʻokahi i ʻoi aku ma mua o 10 square a emi iho ma mua o 35 square, hiki ke koho ʻia e like me nā kūlana kahua;inā ʻoi aku ka mana o ka inverter ma mua o 60 kW a ʻoi aku ka ʻāpana cross-sectional o kahi kaula hoʻokahi ma mua o 35 square, ua ʻōlelo ʻia e koho i nā kaula hoʻokahi maʻalahi e hana a ʻoi aku ka liʻiliʻi o ke kumukūʻai.
