He aha te rerekētanga i waenga i te AC me te DC?

Hei wāhanga matua o te whatunga hiko, Ngā Whakawhiti Mana kei te pūtake o te tohatoha me te whakamahi i te hiko. Engari ko te hiko e rere ana i roto i ēnei whakawhiti hiko e rua ngā āhua matua: te Au Hurihuri (AC) me te Au Tika (DC). He mea nui te mārama ki te rerekētanga ki te mārama ki ngā pūnaha hiko o ēnei rā.

I[Te Tari Hauora Tūmatanui], he tohunga kiwhakawhiti hikoI roto i te hangahanga, ka mahi mātou ki te hiko AC i ia rā, i ia rā. I roto i tēnei tuhinga, ka whakamāramahia e mātou te rerekētanga i waenga i te AC me te DC, he aha i noho ai te AC hei paerewa mō ngā whatunga hiko, me te wāhi e hiahiatia ai te DC.

Te Rerekētanga Matua: He Whakataurite Māmā

Whakaarohia te rere o te hiko me te wai e rere ana i roto i te paipa.

 

Iahiko Tika (DC)he rite ki te wai e rere anapumau tonu i te huarahi kotahiiho i tētahi paipa tika. He mea matapae, he ōrite hoki.

Iahiko Whakawhiti (AC)he rite ki te waie tere haere ana i mua, i mua hoki me te manawatakii roto i te paipa. Kore te nekehanga kupenga, engari kei te whakawhitihia tonutia te pūngao mā roto i te nekehanga.

 

Ko tēnei rerekētanga taketake i roto i tete ahunga o te rereKoia te mauri o te AC me te DC.

 

 

Whakataurite taha-ki-taha: AC me DC

 

 

Te Ruku Hōhonu ki Ngā Rerekētanga Matua

1. Te Rere me te Aronga o te Au

DC:Ko te kī i konei koTikaKa rere te utu hiko i te ahunga kotahi, kāore e nekenekehia mai i te pito pai ki te pito kino. Whakaarohia he rama hiko e whakamahia ana e te pākahiko; ka rere tika te kaha mai i te pākahiko ki te peera.

Ā:Ko te kī i konei koWhakawhitiwhitiKa huri te ahunga o te utu hiko i ia wā. I roto i te nuinga o ngā pūnaha hiko, ka puta tēnei i te 50, i te 60 rānei ngā wā ia hekona (e inehia ana hei Hertz, Hz). Ko te tikanga o tēnei, kei te wiri haere ngā irahiko i roto i ngā waea o tō whare, e 60 ngā wā ia hekona, kāore e haere tonu ana i roto i te porowhita.

2. Te "Pakanga o ngā Au" me te Take i Toa ai a AC mō te Tukunga Ipurangi

Ehara tēnei i te hītori noa iho; koinei te take matua i hangaia ai tā tātou whatunga hiko ki runga i te AC, ā, nō reira, he aha aingā whakawhiti hikohe tino arohaehae.

I te mutunga o te rautau 19, i tautoko a Thomas Edison i te DC, ko Nikola Tesla rāua ko George Westinghouse i tautoko i te AC. I toa a AC i te "Pakanga o ngā Au" mō tētahi take matua:te āheinga ki te whakarerekē.

Te raruraru o te tuku hiko DC:Ina haere te hiko i tawhiti, ka tūtaki ki te ātete i roto i ngā waea, ka ngaro te hiko hei wera. Hei whakaiti i tēnei ngaronga, me tuku te hiko i te tere tino tere.ngaohiko teiteikātahi ka "heke iho" ki tētahi wāhi haumaru, iti hoki te ngaohiko mō ngā kāinga me ngā pakihi.

Te Koha Whakamate a DC:I te tekau tau atu i 1880, kāore he huarahi whai hua, whai hua hoki hei whakanui, hei whakaiti rānei i te ngaohiko DC.

Ngā Painga Toa a AC:Ka taea te whakanui ake (whakapiki ake) me te whakaiti (whakaheke iho) i te ngaohiko AC mā te whakamahi i tētahi taputapu e kiia nei ko tewhakawhiti.

Koinei te wāhi e puta mai ai ō mātou pūkenga.Ngā whakawhiti hikoI ngā teihana whakaputa hiko, whakanuia te ngaohiko AC ki ngā taumata tino tiketike (pērā i te 400,000 volts, neke atu rānei) kia pai ai te tuku hiko tawhiti me te iti o te ngaronga. Kātahi, i ngā teihana hiko tata ki ngā wāhi taupori, ka whakaitihia e ētahi atu whakawhiti hiko te ngaohiko ki te 120/240V e whakamahia ana e tātou i roto i ō tātou kāinga.

Nā te ngāwari o te whakawhiti i te ngaohiko i noho ai te AC hei paerewa tūturu mō ngā whatunga hiko o te ao.

3. Ngā Whakamahinga Hou: Te Wāhi e Tiaho ai ia Mea

Ahakoa te mana o te hiko AC i runga i te whatunga hiko, ehara i te mea kua tawhito te hiko DC. He tino pai ia momo i roto i tōna ake rohe:

Ko te AC te mea pai mō:

Te whakakaha i ngā tāone me ngā kāinga katoa.

Ngā motuka me ngā mīhini ahumahihe māmā ake, he pono ake hoki i runga i te AC.

Ngā tono mana-teiteipērā i te whakamahana me te rama.

He mea nui te DC mō:

Ngā Hikohiko:Ka whakahaerehia tō waea, tō pona, tō pouaka whakaata, me ngā taputapu matihiko katoa i runga i te hiko DC. Koia te take he kaitahuri AC-ki-DC ā rātou urutau hiko (ngā "kaituku hiko" rānei).

 

Ngā Pūhiko:Ka rongoa, ka tukuna hoki te hiko DC e ngā pākahiko katoa (tae atu ki ērā o ngā EV).

 

Mana Pūngao o te Rā:Ka whakaputahia e ngā panera rā te hiko DC, e hiahiatia ana he kaitahuri hei huri i te hiko ki te AC mō te whakamahi i te kāinga.

 

Ngā Waka Hiko:Ka whakamahia e ngā pākahiko hiko te DC, ā, kei te noho hei paerewa ngā teihana utu tere DC.

 

Whakamutunga: He Hononga Mahi Tahi

Ehara te rerekētanga i waenga i te hiko AC me te hiko DC i te mea ko tēhea te mea pai ake; engari ko tēhea te mea tika mō te mahi. Ko te ao hou e whakawhirinaki ana ki tētahi hononga matatau i waenganui i a rāua.

 

ACko ia te toa ote tuku me te tohatoha hiko tawhiti, i whakaāheitia e te hunga whakaiti engari he mea nuiwhakawhiti hiko.

 

DCko ia te toa ote rokiroki pūngao me ngā taputapu hiko matihikoe whakakaha ana i ō tātou oranga o ia rā.

 

ITe Tari Hauora Tūmatanui, he tohunga mātou ki te taha AC o tēnei hononga. Ka hoahoa mātou, ka hanga hoki i ngā mea ponongā whakawhiti hikoe hanga ana i te tuara o te hanganga hiko, kia pai ai te tuku me te haumaru o te hiko AC e whakaputaina ana i te tipu ki tō tatau.
