E hōʻuluʻulu

ʻO ka mālama ʻana i kahi ʻōnaehana coding kala uea kūpono e hōʻoia i ka palekana a me ka maʻalahi. I kekahi manawa hiki i kēia ke pale i kahi pōʻino make. A i ʻole i kekahi manawa hiki ke kōkua iā ʻoe e palekana i ka wā o kahi papahana. ʻO ia ke kumu i kēia lā ke koho nei mākou i kahi kumuhana maʻalahi me ʻelua pane. He maikaʻi a maikaʻi ʻole paha ka uea ʻeleʻele?

ʻO ka mea maʻamau, pili ka polarity o ka uea ʻeleʻele i ke ʻano o ke kaapuni. Inā ʻoe e hoʻohana nei i kahi kaapuni DC, ʻo ka uea ʻulaʻula no ke au kūpono a ʻo ka uea ʻeleʻele no ke au ʻino. He keʻokeʻo a hinahina paha ka uwea honua inā hoʻopaʻa ʻia ke kaapuni. Ma kahi kaapuni AC, maikaʻi ka uea ʻeleʻele a maikaʻi ʻole ka uea keʻokeʻo. He uliuli ka uwea lepo.

Inā ʻaʻole maopopo ʻoe i ka polarity o ka uea ʻeleʻele, eia kahi wehewehe maʻalahi. Ma nā kaapuni DC, ʻo ka uea ʻeleʻele ka uea maikaʻi ʻole. I nā kaapuni AC, ʻo ka uea ʻeleʻele ka uea maikaʻi. No laila, he mea nui e hoʻoholo i ka ʻōnaehana kaapuni ma mua o ka hoʻoholo ʻana i ka polarity o ka uea ʻeleʻele. Akā naʻe, huikau ka hapa nui o nā kānaka. ʻO ka hana ʻana pēlā hiki ke hoʻopōʻino i nā mea uila.

Nā ʻano code kala uea like ʻole

Ma muli o ke ʻano o ke kaapuni, hiki iā ʻoe ke hālāwai me nā code kala uea like ʻole. ʻO ka ʻike ʻana i kēia mau code kala uea e pōmaikaʻi iā ʻoe ma nā ʻano he nui. ʻO ka mea nui, e hōʻoia i ka palekana. Maʻaneʻi, manaʻolana wau e kūkākūkā i nā code kala uila DC a me AC.

Nā Code kala Uea Mana DC

ʻO ke au pololei, ʻike ʻia hoʻi ʻo ke au pololei, hele ma kahi laina pololei. Eia nō naʻe, ʻaʻole hiki ke hoʻoili ʻia ka mana DC ma kahi lōʻihi e like me ka mana AC. ʻO nā pākahi, nā wahie a me nā pūnaewele lā nā kumu mana DC maʻamau. ʻO kahi ʻē aʻe, hiki iā ʻoe ke hoʻohana i kahi rectifier e hoʻololi i ka AC i DC.

Eia nā code kala uea no ka mana DC.

Uea ulaula no ke au maikai.

Uea ʻeleʻele no ke au ʻino.

Inā he uwea honua ka DC kaapuni, pono ke keʻokeʻo a hina paha.

E hoʻomanaʻo: ʻO ka pinepine, ʻekolu mau uea ka DC kaapuni. Akā i kekahi manawa e loaʻa iā ʻoe ʻelua uea. Hoʻopaʻa ʻia ka uwea nalowale.

Nā Code kala Uea Mana AC

Hoʻohana pinepine ʻia ka ʻauwaʻa alternating, i ʻike ʻia ʻo ia hoʻi ma nā hale a me nā ʻoihana. Hiki ke hoʻololi i ka mana AC i kēlā me kēia manawa. Hiki iā mākou ke kuhikuhi i ke ala ʻokoʻa ma ke ʻano he hawewe sine. Ma muli o ka nalu, hiki i ka mana AC ke hele mamao aku ma mua o ka mana DC.

Ma nā voltages like ʻole, ʻokoʻa ke ʻano o ka mana AC. Eia kekahi laʻana,ʻo nāʻano voltage maʻamauʻo 120V, 208V a me 240V. Hele mai kēia mau voltage likeʻole me nā māhele he nui. Ma kēia pou, e kamaʻilio mākou e pili ana i ka mana ʻekolu-phase.

ʻEkolu mau mana

ʻO kēia ʻano mana AC he ʻekolu uea ola, hoʻokahi uea kūʻokoʻa, a hoʻokahi uea honua. No ka mea hiki mai ka mana mai ʻekolu mau uea like ʻole, hiki i kēia ʻōnaehana 1-phase ke hāʻawi i ka mana nui me ka maikaʻi maikaʻi. (XNUMX)

Eia nā code kala uea no ka mana AC.

He ʻeleʻele ka uea māhele 1, a ʻo ia ke kelepona wela ʻeleʻele a mākou i ʻōlelo ai ma mua o ka ʻatikala.

He ʻulaʻula ka uea Phase 2.

Pono ka uea Phase 3 i uliuli.

ʻO ka uea keʻokeʻo ka uea kūʻole.

He ʻōmaʻomaʻo a ʻōmaʻomaʻo paha ka uea honua me nā kaha melemele.

E hoʻomanaʻo: ʻO nā uea ʻeleʻele, ʻulaʻula a me ka uliuli, he mau uea wela i kahi pilina ʻekolu. Eia naʻe, hiki ke loaʻa i nā uea ʻehā wale nō i kahi pilina hoʻokahi; ʻulaʻula, ʻeleʻele, keʻokeʻo a me ka ʻōmaʻomaʻo.

E hōʻuluʻulu

Wahi a ka National Electrical Code (NEC), ʻo nā code kala uea ma luna nei he mau wili uila US. No laila, e hahai i kēia mau alakaʻi i kēlā me kēia manawa e hana ana ʻoe i kahi papahana uea. E mālama pono iā ʻoe a me kou home. (2)

E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
