He aha ka2 pin mana kaula me ka SAA palapala? ʻEhia mau ʻano o nā kaula kaula ma ka mākeke i kēia lā? E ʻike kākou i ka ʻike pono e pili ana i kēia huahana ma o ka ʻatikala ma lalo nei.
ʻO ke kaula mana he laina huahana maʻamau e huki i nā laina pūnaewele, nā laina hoʻouna hōʻailona no nā mea lekiō. Eia naʻe, i loko o kēia huahana he nui nā ʻano like ʻole. No laila he aha kā lākou hoʻohana kikoʻī? E hahai i ka ʻatikala ma lalo nei no ka loaʻa ʻana o ka ʻike pono hou e pili ana i ke kaula uila.
He aha ke kaula uwea?
Uaʻike muaʻia nā kaula pūnaewele Cordial i ka makahiki 1880. A hiki i kēia lā, uaʻoi aku ka nui o nā mea maʻamau i nāʻoihana uila a me ka uila. I ke kumu,ke kaula mana me ka palapala SAAhe uwea uila i loko o ke kumu. Loaʻa iā ia kahi dielectric nui e pale ai i ka hele ʻana o ke au.
Ma waho aʻe o kēia papa, ua ʻōwili nā kānaka i kahi papa hou o ke kaula hao; ʻo ka ʻaoʻao waho loa he ʻūhā hoʻopololei. Pēlā nō, ʻo ka huahana uea maʻamau maʻamau ka uea antenna i kāu TV.
ʻO ka noi maikaʻi loa o ke kaula mana 2 pin me ka palapala SAA
No ke aha i kaulana ai kēia laina huahana e like me2 pin mana kaula me ka SAA palapala?Loaʻa kēia inoa mai ka ʻoiaʻiʻo e kaʻana like nā uhi āpau i kahi axis geometric maʻamau. Loaʻa i kēlā me kēia ʻāpana i loko o ka ʻōnaehana cordial network kāna hoʻohana ponoʻī e hāʻawi i ka hoʻouna hōʻailona maikaʻi loa no nā mea hoʻohana.
Hoʻohana i nā kaula pūnaewele - nā kaula mana
He mea maʻamau nā huahana kaula uila ma ka ʻupena kīwī uwea. Hele mai kēia ma kāna hoʻouna hōʻailona maikaʻi loa. Maikaʻi: hiki i ka wikiwiki o ka hoʻouna ke hiki i 35Mbps a i ʻole hiki ke hoʻouna i ka ʻikepili me ka wikiwiki e like me nā haneli o MHz. Eia kekahi, ʻoi aku ka maikaʻi o ka hiʻohiʻona hoʻoili hōʻailona ma mua o nā kaula keleawe maʻamau.
Nui nā hoʻohana like ʻole o ke kaula mana 2 pin me ka palapala SAA
Ma waho aʻe o ke kīwī uwea, ʻike nui ʻia ke kaula mana i nā lawelawe pūnaewele kiʻekiʻe, nā kāmela kiaʻi, kelepona, VoilP, a pēlā aku.
Lawe ke kaula i nā hiʻohiʻona a pau o ka mana maʻamau2 pin mana kaula me ka SAA palapala.kikoʻī:
●Hoʻokumu ʻia ma nā laina ʻenehana Iapana, nā kaula maoli e hana i ka hilinaʻi piha i ka maikaʻi o ka huahana i hoʻopau ʻia.
.ʻO ke kumu keleawe o ke kaula a hiki i ka 1.02mm mānoanoa
.Hoʻokumu ʻia ka ʻāpana solvent-insulating me FPE plastic material, e hāʻawi ana i ka lōʻihi kiʻekiʻe a pale i ka lawe ʻana i ka mana kiʻekiʻe i waho.
Hoʻemi maikaʻi ka papa pālua anti-interference i ka nalowale o ka lawe ʻana
●ʻO ka pahu waho i hanaʻia i nā mea PVC no ka ikaika nui a me ka pale kaula, e hoʻonui i ke ola o ka lawelawe
● Eia kekahi, hoʻohui pono i nā kaula mana ma nā kaula
●Similarly, kiʻekiʻe uwea ikaika, inert pane i nā mea a pau maʻamau kūlana
Me kēia pūʻulu o nā hiʻohiʻona, hāʻawi maikaʻi nā ʻoihana ʻoihana2 pin mana kaula me ka SAA palapala. .
He nui nā ʻano ʻano like ʻole o nā kaula kaula:
Ke hoʻohālikelike ʻia me nā ʻano huahana ʻē aʻe, ʻo 2 pin ka mea maʻalahi loa ma ka mākeke a ʻo ia ka mea maʻamau. ʻO ka ʻokoʻa o kēia ʻano uea, ʻo ia ka uhi ʻana i ka metala anti-interference e hoʻokaʻawale ana i ke kaula mai ka pahu plastik waho.
No laila, ua kapa ʻia ke ʻano me kēia papa anti-interference he kelepona FTP; kapa ʻia kekahi he uwea UTP. Eia kekahi, ʻoi aku ka maikaʻi o ka hoʻouna ʻana i ka hōʻailona o ka uea 2pin.
2 Pin Uku Mana
ʻO ka maikaʻi o kēia ʻano kelepona i hoʻohālikelike ʻia me ke kaula mana 2pin ʻo ia ka hiki ke hoʻouna i nā hōʻailona ikaika a ʻoi aku ka maikaʻi o ka hoʻohaʻahaʻa ʻana i ka leo hoʻouna.
Nā Uila Mana 3 Pin
Nui ka poʻe e kāhāhā i ka wikiwiki o ka hoʻouna ʻana i ka hōʻailona o2 pin mana kaula me ka SAA palapala. Mahalo i kēlā, paʻa mau ka laina hoʻouna a ʻo ka hoʻouna maikaʻi loa.
No ke aha ʻoe e pono ai i ke kaula mana 2 pin me ka palapala SAA?
ʻO kēia paha ke ʻano o ka conductor me ka wikiwiki a me ka ikaika o ka hoʻouna ʻana i nā hōʻailona o nā huahana āpau i luna. I kēia alakaʻi, ua hoʻonui nui ʻia ka maʻamau o kēlā me kēia ʻāpana:
● ua hoʻonui nui ʻia ka mānoanoa o nā ʻuala o nā cores
●ʻoi aku ka hoʻomohala anti-interference shell, me ka nui anti-interference hiki
●Pēlā hoʻi, ʻo ka ʻili o waho e hōʻoia i ka maikaʻi maikaʻi e kūʻē i nā kūlana o ka wā.
He mea maʻamau kēia ʻano uea no ka hoʻouna ʻana i nā hōʻailona ma kahi lōʻihi, kokoke i ka paʻa ʻana i ke kūlana o ke kaula mana nui no nā ʻōnaehana uwila televise.
Uea, uwea a me ke kaula - he mea nui nā ʻokoʻa?
A aia kekahi mau ʻokoʻa? ʻO ka maikaʻi o nā hana uila e ʻōlelo maopopo ʻole aia aia, a he mau mea koʻikoʻi. Akā ʻo ka hapa nui o nā "mea hoʻohana uila" e ʻike pono2 pin mana kaula me ka SAA palapala.
No ke aha e noʻonoʻo ʻole ai i hoʻokahi manawa a no nā mea āpau, e kau ana i nā "i" āpau? Eia kekahi, ʻaʻole paʻakikī loa: heluhelu wale nō! He laʻana abstract: ʻike pono kēlā me kēia o mākou i ka ʻokoʻa o kahi kaʻa kaʻa, kahi SUV a me kahi kaʻa.
ʻO kahi kūlana like me ka uwea, ke kaula a me ke kaula! ʻO lākou a pau he mau ʻelele o ka ʻohana hoʻokahi - ka ʻohana o nā huahana kelepona. A ʻaʻole ʻoi aku ka paʻakikī o ka hoʻokaʻawale ʻana iā lākou ma mua o kā mākou hiʻohiʻona mai ka honua huila.
He aha nā mea a mākou e hoʻohana ai i ke kaula mana 2 pin me ka palapala SAA?
Akā ma kahi o ka polyethylene, aia paha ka wili a i ʻole ka braid i hana ʻia i nā mea fibrous a i ʻole uea. He mea nui nō hoʻi ka maʻalahi o ka uea i ka insulate - ʻo ia hoʻi, ke kumu conductive i loko o ke kāʻei o Adamu lāua ʻo Eva (uaea ʻole). ʻO ka hoʻolālā kikoʻī o2 pin mana kaula me ka SAA palapalapili i ke kumu. ʻO ka makani manuahi he mea ia no nā uwea ʻole (PSO, PS, A, AC, etc.).
He mea maʻamau ia ma nā laina hoʻouna ma luna; akā, ua maʻa mau nā uea i hoʻopaʻa ʻia iā ia iho. He mea maʻamau nā uea insulated ma nā ʻupena home. ʻO kahi kikoʻī koʻikoʻi: ʻaʻole manaʻo ka uea no ka moe ʻana ma lalo o ka lepo a i ka wai. ʻO ia ke kumu, ʻoiai he ʻokoʻa paha nā sheaths, ʻoi aku ka haʻahaʻa o nā conductors i ka hoʻohālikelike ʻana i ke kaula.
ʻO ka hoʻohana ʻana i nā ʻano ʻokoʻa o ka insulation a me nā busbar uea ka mea maʻamau no ka hōʻailona ʻana i ke kaula:
●Ua hōʻailona ʻia ka vein phase i ka ʻeleʻele a me ka ʻeleʻele;
● Eia kekahi, nā uea kū ʻole - uliuli;
●Similarly, grounding conductors – melemele-'ōmaʻomaʻo kala kala.
Ka lā pau o ke kaula mana
Hiki ke ʻokoʻa ka manawa maoli o ka hoʻohana ʻana i ka huahana e like me nā ʻano ʻenehana maʻamau. No nā kaula me ka insulation plastic, ʻo ka lōʻihi maoli a me ka manawa o ka hoʻohana ʻana ma kahi o 25 mau makahiki. He maʻalahi ka hoʻohana ʻana i nā uea pepa impregnated no 30 mau makahiki.
