Introduction to buspā
ʻO nā Busbars nā mea nui i nā ʻōnaehana hoʻoili mana a he mau ala conductive e hoʻomaʻamaʻa i ka hoʻoili pono ʻana o ke au uila. ʻOiai ʻo ka keleawe ka mea i koho maʻamau no nā busbars ma muli o kona conductivity maikaʻi loa a me nā waiwai mechanical, ke waiho nei ka nīnau: pono ke keleawe ka busbar? E ʻimi ana kēia ʻatikala i nā mea like ʻole i hoʻohana ʻia no nā busbars, nā pono a me nā pōʻino o ke keleawe, a me nā mea ʻē aʻe i hiki ke hoʻohana pono ʻia i nā noi like ʻole.
pahu pahu keleawe
ʻOi aku ka maikaʻi o ka uila
ʻIke ʻia ʻo Copper no kāna conductivity uila kiʻekiʻe, ma kahi o 59.6 x 10^6 S/m. Hāʻawi kēia waiwai i nā busbar keleawe e lawe i nā au kiʻekiʻe me ka liʻiliʻi o ka nalowale o ka ikehu, e kūpono ana iā lākou no nā noi hana kiʻekiʻe. ʻO ka conductivity maikaʻi o Copper e hōʻoia i ka holo pono ʻana o nā ʻōnaehana uila, e hōʻemi ana i ka pilikia o ka wela a me ka pau ʻole o ka ikehu.
ʻO ke kūpaʻa ʻino
ʻO kekahi pōmaikaʻi koʻikoʻi o ke keleawe, ʻo ia kona kūpaʻa kūlohelohe i ka corrosion. Hoʻonui kēia hiʻohiʻona i ka lōʻihi a me ke ola lawelawe o ka busbar keleawe, ʻoi aku ka nui ma nā wahi kahi e loaʻa ai ka wai a i ʻole nā mea ʻino. ʻO ke kūpaʻa corrosion o Copper e kōkua i ka mālama pono ʻana i ka pilina uila, e hōʻoia ana i ka hana hilinaʻi lōʻihi.
Ikaika Mechanical
Loaʻa i ke keleawe ka ikaika mechanical maikaʻi loa, e ʻae iā ia e kū i ke kaomi a me ke koʻikoʻi me ka ʻole deforming. He mea koʻikoʻi kēia hiʻohiʻona i nā noi kahi e hiki ai i ka busbar ke haʻalulu a hoʻonui paha i ka wela. Hāʻawi ka ikaika mechanical o nā busbar keleawe i ko lākou hilinaʻi a palekana i nā ʻōnaehana uila.
Nā mea ʻokoʻa no nā busbars
aluminika
ʻOiai he koho kaulana ke keleawe, hoʻohana nui ʻia ka alumini ma ke ʻano he mea ʻē aʻe no nā busbars. Loaʻa i ka alumini ka conductivity uila ma kahi o 37.7 x 10^6 S/m, ʻoi aku ka haʻahaʻa ma mua o ke keleawe akā lawa nō naʻe no nā noi he nui.
Nā pōmaikaʻi o ka pahu pahu alumini
Māmā: ʻOi aku ka māmā o ka alumini ma mua o ke keleawe, e maʻalahi ai ka lawelawe ʻana a me ka hoʻouka ʻana. Hoʻohana pono kēia hiʻohiʻona i nā noi paona, e like me nā kaʻa uila a me ka aerospace.
Kūʻai-pono: ʻO ka ʻōlelo maʻamau, ʻoi aku ka liʻiliʻi o nā busbar alumini ma mua o ke keleawe, e hoʻolilo iā lākou i koho kūpono no nā papahana he nui.
lawa pono conductivity: ʻOiai he haʻahaʻa haʻahaʻa ka alumini, hiki iā ia ke lawe i ka nui o kēia manawa me ka maikaʻi, ʻoiai ke hoʻolālā ʻia me kahi ʻāpana cross-sectional nui.
Busbar hao keleawe
Hoʻohana ʻia nā ʻāpana keleawe e like me ke keleawe a i ʻole ke keleawe i kekahi manawa no nā busbars e hoʻohui i nā pono o ke keleawe me kāna mau waiwai mechanical i hoʻonui ʻia. Hiki i kēia mau mea hoʻohui ke hāʻawi i ka hoʻonui i ka ikaika a me ke kūpaʻa ʻana, e kūpono iā lākou no nā noi kikoʻī.
ʻO nā pōmaikaʻi o ka busbar copper alloy
Hoʻonui i ka ikaika: Hiki i nā'āpana keleawe ke hāʻawi i ka ikaika mechanical kiʻekiʻe ma mua o ke keleawe maʻemaʻe, e kūpono iā lākou no nā kaiapuni kiʻekiʻe.
ʻO ke kūpaʻa ʻino: He nui nā keleawe keleawe i kū'ē i ka corrosion maikaʻi, hiki ke hoʻonui i ke ola lawelawe o ka busbar ma lalo o nā kūlana koʻikoʻi.
Nā Mea Hana ʻē aʻe
Ma waho aʻe o ke keleawe a me ka alumini, hana ʻia nā busbars i nā mea ʻē aʻe e like me ke kila kila a me nā mea hoʻohui i nā noi kūikawā.
Pahu pahu kila kila
ʻO ke kila kila maikaʻi ke kūpaʻa ʻana i ka corrosion a me ka ikaika mechanical, kūpono i nā wahi kahi e pono ai nā waiwai ʻelua. Eia naʻe, ʻoi aku ka haʻahaʻa o kona conductivity ma mua o ke keleawe a me ka aluminika, hiki ke kaupalena i kona hoʻohana ʻana i nā noi kiʻekiʻe.
Pākuʻi huikau
Ke ʻimi ʻia nei nā mea hoʻohuihui, ʻo ia hoʻi ka hui pū ʻana o nā mea metala a me nā mea insulating, no nā noi busbar. Hiki i kēia mau mea ke hāʻawi i nā waiwai kūʻokoʻa e like me nā hale māmā a me ka hoʻokele thermal i hoʻonui ʻia.
Nā mea e pili ana i ke koho mea
Ke hoʻoholo nei inā pono ke keleawe no nā busbars, pono e noʻonoʻo ʻia kekahi mau mea:
1. Hiki ke halihali i kēia manawa
Pili pololei ka conductivity o kekahi mea i kona hiki ke lawe i ke au uila. No nā noi me nā koi o kēia manawa, ʻoi aku ka nui o nā mea conductive e like me ke keleawe. Eia nō naʻe, hiki i ka alumini ke lilo i mea ʻē aʻe inā hoʻolālā pono ʻia.
2. Nā kūlana kaiapuni
He mea koʻikoʻi ke kaiapuni hana i ke koho ʻana i nā mea. Inā ʻike ʻia nā busbars i ka makū a i ʻole nā mea corrosive, ʻoi aku ka maikaʻi o nā mea me ke kūpaʻa kiʻekiʻe o ka corrosion, e like me ke keleawe a i ʻole kekahi.
3. Kaumaha a me ka hakahaka
Ma nā noi kahi e hopohopo ai ke kaumaha, e like me ka halihali a i ʻole aerospace, makemake ʻia nā pahu pahu alumini no ko lākou kaumaha māmā.
4. Noonoo Kumukuai
Hiki i nā kaohi kālā ke ho'ololi nui i ke koho waiwai. ʻOiai he waiwai maikaʻi ke keleawe, ʻoi aku ka maikaʻi o ka alumini no kekahi mau noi.
i ka hopena
I ka hōʻuluʻulu ʻana, ʻoiai ʻo ke keleawe he koho kūpono a kuʻuna no nā busbars ma muli o kona conductivity maikaʻi loa, ka pale ʻana i ka corrosion, a me ka ikaika mechanical, ʻaʻole ia wale ke koho. ʻO ka aluminika, nā ʻāpana keleawe, ke kila kila a me nā mea hoʻohuihui hiki ke lilo i mau mea ʻē aʻe, ma muli o nā koi kikoʻī o ka noi. He mea koʻikoʻi ka hoʻomaopopo ʻana i nā pōmaikaʻi a me nā palena o kēlā me kēia mea i ka hoʻoholo ʻana i ka manaʻo e hoʻomaikaʻi i ka pono a me ka hilinaʻi o nā ʻōnaehana hoʻoili mana. ʻO ka mea hope loa, pono e hoʻokumu ʻia ke koho ʻana i nā mea busbar ma ka loiloi akahele o nā koi noi, nā kūlana kaiapuni, a me nā noʻonoʻo kālā.
