He kūpono ia no ka AC 3-phase eha-wire, ʻekolu-phase five-wire system, frequency 50 ~ 60Hz, helu volta a hiki i 690V, helu ʻia e hana ana i kēia manawa 250 ~ 5000A lako a me ka hāʻawi ʻana i nā ʻōnaehana, ma ke ʻano he mea kōkua no ka lako a ka hāʻawi ʻana i nā lako hana i ka ʻoihana, mining, ʻoihana a me nā hale kiʻekiʻe, kūpono loa no ka hoʻololi ʻana i nā hale hana a me nā ʻoihana kahiko.Hoʻopaʻa ʻia ka hui ʻana o ka pahu busbar paʻa me nā bolts insulating, ʻoiai ke hoʻohana ʻia ka lālani keleawe lua e hoʻopili ai, e hoʻonui pono i ka wahi pili o ka hui a hoʻemi nui i ka piʻi ʻana o ka wela o ka ʻāpana hui.Hoʻopili ʻia nā lālani conductive o ka busbar paʻa me ka lapalapa-retardant cross-linked polyethylene heat-shrinkable lima lima, nona nā waiwai insulating ikaika a ʻaʻole e hoʻokuʻu i nā kinoea ʻawaʻawa i ke ahi.
Inā kiʻekiʻe loa ka mahana o ka ʻauwai busbar, e hāʻule.I mea e palekana ai, pono mākou e hoʻomaopopo i ke ala e hoʻomāalili ai i ka pahu pahu paʻa i mea e pale aku ai i ka wela kiʻekiʻe e pili ana i ka busbar.
Haʻahaʻa-voltage laina laina uwea, uwea, uwea, lālā paa busbar trough, bare conductive bar, puncture cable, etc.ʻO ka huahana like, ka uea nui like, ma o ka manawa like, i ka piʻi ʻana o ka wela wela e hoʻololi pū ʻia ka hana;ma muli o nā hoʻolālā like ʻole o ka ʻāpana cross-sectional, ʻokoʻa ka piʻi ʻana o ka mahana.ʻOiaʻiʻo, ke piʻi ka mahana a piʻi ka waiwai kū'ē, piʻi ke kaomi a piʻi ka nalowale o ka ikehu.
ʻO ka pahu busbar paʻa ka like, no laila, ua helu ʻia ka conductivity dense busbar conductor e like me ke kahe o kēlā me kēia square millimeter he hewa, hoʻolālā hoʻolālā, hoʻopau wela, akā pili like ka impedance, inductance a me nā mea ʻē aʻe i ka hiki ke lawe i kēia manawa.No laila ʻo Gb7251 - 2006 National Standard e kuhikuhi ana i ka piʻi ʻana o ka wela o ka palena o kēia manawa no ka hoʻoholo ʻana i ka hiki ke halihali i ka pahu busbar paʻa.
No laila, pono e ana ʻia ka waiho ʻana o nā pahu busbar ma ka pūnaewele, ʻo ka lōʻihi o ka laina laina e pono ai ke kiʻekiʻe kiʻekiʻe, a ʻo ke kiʻekiʻe o ka pahu hoʻololi plug-in o nā pahu busbar dense e hoʻoholo ʻia e like me ka hoʻolālā.Ke hūnā ʻia nā laina hoʻolaha ahi, pono e waiho ʻia i loko o ka hale non-combustible, a ʻo ka mānoanoa o ka pale pale ʻaʻole e emi ma lalo o 30 mm.ke waiho ʻia ma kahi ākea, pale ʻia nā paipu metala a i ʻole ka pahu metala me ka pena ahi, no ka mea, ʻaʻohe hana pale ahi i nā paipu metala a me nā pahu metala.I ka hoʻohana ʻana i ka insulation a me ka sheathing no nā mea hiki ʻole ke puhi ʻia o ke kaula, ʻaʻole hiki ke komo i ke kumu i ka paipu metala, ka pale ʻana i ka metala, akā ʻo ka laina ma ka papahele o ke kumu, pono e hele i ka paipu pā, pale slot, luna a ʻelua mau wēlau o ka paipu, pono e hoʻopaʻa ʻia ka ʻāpana waha e hoʻopaʻa i ka ʻāpana.
