He maikaʻi a maikaʻi ʻole paha ke kelepona ʻeleʻele?

ʻO nā uea lālā hāʻawi mana AC a me DC ua hoʻopaʻa ʻia i nā kala e maʻalahi ke ʻike ma waena o nā uea like ʻole. I ka makahiki 2006, ua hui like na koho kala uwea UK me na koho kala uwea ma ke koena o ka aina o Europa e like me ka IEC 60446. No ka hopena o na hoololi ana, ua lilo ka uea polū i ka uwea neutral a o ke kaha omaomao/melemele. lepo. , a ʻo ka uea ʻeleʻele i kūkākūkā ʻia ma kēia ʻatikala he uea ola. Ke nīnau nei paha ʻoe, he maikaʻi a maikaʻi ʻole paha ka uwea brown?

E hoʻomau i ka heluhelu no ka hoʻomaopopo pono ʻana i ka hoʻohana ʻana a me nā hana o ka uea ʻeleʻele (ola).

Uea Brown: maikaʻi ʻole?

I loko o ka International Electrotechnical Commission (IEC) DC mana uwila kala code, ka brown uea, i kapaia ola uea, oia ka maikai uea, lepili "L +". ʻO ka hana o ka uwea ʻeleʻele ka lawe ʻana i ka uila i ka mea hana. Inā ola ka uwea ʻeleʻele a ʻaʻole i hoʻopili ʻia i kahi uwea lepo a kū ʻole paha, aia paha kahi manawa e hiki ai iā ʻoe ke wili. No laila, ma mua o kou hoʻomaka ʻana e hana i ka uwea, e hōʻoia ʻaʻole i hoʻopili ʻia kahi kumu mana i ka uwea ola.

Ka hoʻomaopopo ʻana i nā code kala uila

Ma muli o ka hoʻololi ʻana i nā code kala uwila, ʻo nā mains paʻa a me nā uwila uila, a me nā uwea maʻalahi, i kēia manawa ua loaʻa nā uea like ʻole. Aia ma UK ka ʻokoʻa ma waena o kā lākou kala uea kahiko a me nā kala hou.

Ua pani ka uwea neutral polū i ka uwea neutral black mua. Eia kekahi, ʻeleʻele ke kelepona ʻulaʻula kahiko. Pono e hoailona pono ia na uwea me na code kala uwea kupono ina he huikau o na kala kahiko a me na uwea hou e pale aku ai i ka pili hewa ole o ka mahele a me ke ku ole. Lawe ka uea polū (neutral) i ka mana mai ka mea kani, a me ka uwea brown (ola) hāʻawi i ka mana i ka mea kani. Ua ʻike ʻia kēia hui ʻana o nā uea he kaapuni.

ʻO ka uwea ʻōmaʻomaʻo/melemele (ʻāina) kahi kumu palekana koʻikoʻi. ʻO ka hoʻoili uila o kekahi waiwai e hahai mau i ke ala i ka honua e hōʻike ana i ka liʻiliʻi loa. I kēia manawa, hiki i ka uila ke hele i loko o ke kino o ke kanaka ma ke ala o ka honua ke hoʻopōʻino ʻia nā kaula ola a kū ʻole paha, hiki i kēia ke hoʻonui i ka pilikia o ka haʻalulu uila. I kēia hihia, hoʻopaʻa pono ke kelepona ʻōmaʻomaʻo/melemele i ka mea hana, e pale ana i ka hana ʻana.

Manaʻo: Pono e hōʻailona ʻia nā uea paʻa a me nā kaula o nā kala like ʻole, a me nā mea hoʻokomo me nā kaulahao. Pono e kaha ʻia kēia ʻōlelo aʻo ma ka papa fuse, ka mea hoʻopau kaapuni, ka papa hoʻololi a i ʻole ka mea kūʻai aku.

Hoʻohana ʻia ke kala kala i nā keʻena mana DC e hoʻokō me nā kūlana AC, e like me ka mana o ka lā a me nā kikowaena ʻikepili kamepiula.

ʻO kēia ka papa inoa o nā kala kaula mana DC e pili ana i nā kūlana IEC. (1)

Nā noi laʻana

Inā ʻoe i kūʻai hou aku nei i kahi kukui kukui a ke hoʻāʻo nei e hoʻokomo iā ia ma US, e like me ke kukui kaʻa LED a i ʻole ke kukui hale kūʻai. Hoʻohana ka luminaire i nā kūlana uwila honua a me kēia ala, maʻalahi ka maʻalahi:

• ʻO ka uea ʻeleʻele mai kāu mea kukui a i ka uea ʻeleʻele mai kou hale.
• ʻO ka uea polū mai kāu mea kukui a i ka uea keʻokeʻo mai kou hale.
• ʻOmaomao me ke kaha melemele mai kāu mea paʻa i ka uwea ʻōmaʻomaʻo o kou hale.

E hoʻopili paha ʻoe i kekahi mau uwea ola i nā uwea ʻeleʻele a polū o kāu hāmeʻa inā e holo ana ʻoe ma 220 volts a ʻoi aku paha. Eia nō naʻe, pono e hoʻohana ʻia nā volta kiʻekiʻe i nā hihia koʻikoʻi. ʻO ka hapa nui o nā kukui LED hou e koi wale i 110 V, ʻo ia ka lawa. ʻO ke kumu kūpono wale nō ia inā loaʻa nā laina lōʻihi, e like me ka holo ʻana i 200 kapuaʻi a ʻoi aku paha o ka uwea e hoʻomālamalama i nā kahua haʻuki, a i ʻole ke hoʻopili ʻia ka hale i 480 volts.

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

• uwea keʻokeʻo maikaʻi a maikaʻi ʻole
• Pehea e hana ai i nā uwila uila ma kahi haʻahaʻa i hoʻopau ʻole ʻia
• He aha ka nui uwea no ke kukui
