He wāhanga matua te pūtake ngaohiko i roto i te ara iahiko hiko, e whakarato ana i te pūngao hei akiaki i te iahiko hiko mā roto i te ara iahiko. He maha ngā whakamahinga o ngā pūtake ngaohiko whakakotahi hei whakatutuki i ngā whakaritenga mana teitei ake, hei whakatutuki rānei i ngā ngaohiko me ngā iahiko e hiahiatia ana. Ka matapakihia e tēnei tuhinga ngā pūtake ngaohiko whakakotahi, tae atu ki ō rātou whakamāramatanga, ngā momo pūtake ngaohiko, me pēhea te whakakotahi i ngā pūtake ngaohiko, tae atu ki ngā whakamahinga mahi me ngā wero i roto i te whakamahi i ngā pūtake ngaohiko whakakotahi.
Ngā Momo Pūtake Ngaohiko Hiko
Ka taea te whakarōpū i ngā pūtake hiko kia maha ngā momo i runga i ō rātou āhuatanga me ngā whakamahinga:
1. Pūtake Ngaohiko DC (Au Tika): Ka tukuna e tēnei pūtake ngaohiko te au hiko e rere ana i te taha kotahi. Ko ngā tauira o ngā pūtake ngaohiko DC ko ngā pākahiko me ngā pūtau rā.
2. Pūtake Ngaohiko AC (Au Hurihuri): Ka tukuna e tēnei pūtake ngaohiko te au hurihuri i ia wā. Ko ngā tauira o ngā pūtake ngaohiko AC ko ngā whakaputa hiko me te hiko mai i te whatunga PLN.
3. Pūtake Ngaohiko Pūmau: Ka whakaratohia e tēnei pūtake ngaohiko he ngaohiko pumau. Hei tauira, he pākahiko, e pupuri ana i te ngaohiko pumau puta noa i tōna roanga ora.
4. Pūtake Ngaohiko Taurangi: Ka whakaratohia e tēnei pūtake ngaohiko he ngaohiko ka taea te whakarerekē ina hiahiatia. Hei tauira, he pūtake hiko me te ngaohiko putanga ka taea te whakarerekē.
Me pēhea te whakakotahi i ngā pūtake hiko
E rua ngā huarahi matua hei whakakotahi i ngā pūtake hiko: te hono raupapa me te hono whakarara. He rerekē ngā āhuatanga me ngā whakamahinga o ia tikanga.
1. Te Whakakotahi i ngā Pūtake Ngaohiko i roto i te Raupapa
Ina honoa ngā pūtake ngaohiko i roto i te raupapa, ko te ngaohiko katoa ka puta ko te tapeke o ngā ngaohiko mai i ia pūtake. I roto i te whirihoranga raupapa, ka rere te iahiko kotahi i roto i ia pūtake ngaohiko.
\[ V_{\kuputuhi{katoa}} = V_1 + V_2 + V_3 + \cdots + V_n \]
Kei hea:
– Ko te ahotea katoa ko \( V_{\text{total}} \).
– Ko te ngaohiko o ia pūtake ko \( V_1, V_2, V_3, \ldots, V_n \) .
He mea whai hua te whakakotahi i ngā pūtake hiko ā-raupapa ina hiahia tātou ki tētahi hiko teitei ake i tētahi pūtake kotahi. Hei tauira, mēnā e rua ā tātou pākahiko 1.5V, ā, ka honoa ā-raupapa, ko te katoa o ngā hiko ka 3V.
2. Te Whakakotahi i ngā Pūtake Ngaohiko i te Whakarara
Ina honoa ngā pūtake ngaohiko ki te taha whakarara, ka ōrite te ngaohiko katoa e whakaputaina ana ki te ngaohiko o te pūtake kotahi, engari ko te iahiko katoa ko te tapeke o ngā iahiko mai i ia pūtake.
\[ I_{\text{tapeke}} = I_1 + I_2 + I_3 + \cdots + I_n \]
Kei hea:
– Ko te iahiko katoa ko \( I_{\text{total}} \).
– Ko \( I_1, I_2, I_3, \ldots, I_n \) ngā ia o ia pūtake.
He mea whai hua te hono i ngā pūtake hiko whakarara ina hiahia tātou i tētahi iahiko nui ake i te mea ka taea e te pūtake kotahi te whakarato. Hei tauira, mēnā e rua ā tātou pākahiko he 1.5V te iahiko me te iahiko 2A, mā te hono i a rāua i te whakarara ka puta he iahiko katoa o te 1.5V me te iahiko katoa o te 4A.
Ngā Whakamahinga Whaihua o ngā Pūtake Ngaohiko Whakakotahi
He maha ngā whakamahinga mahi e whakamahia ana ngā pūtake ngaohiko whakakotahi, ahakoa iti, ahakoa nui. Ko ētahi tauira:
1. Ngā Pūnaha Rokiroki Pūngao: I roto i ngā pūnaha rokiroki pūngao, pērā i ngā pākahiko mō ngā waka hiko, ka honoa ngā pūtau pākahiko i roto i te raupapa me te whakarara hei whiwhi i te kaha ngaohiko me te iahiko e hiahiatia ana.
2. Ngā Paewhiri Rā: He maha ngā wā ka honoa ngā paewhiri rā i roto i te raupapa me te whakarara hei whakanui ake i te ngaohiko me te iahiko e whakaputaina ana. Mā tēnei ka taea e ngā pūnaha paewhiri rā te whakatutuki i ngā whakaritenga mana teitei ake.
3. Pūnaha Hiko Tārua (UPS): I roto i te pūnaha UPS, ka honoa ngā pākahiko i roto i te raupapa me te whakarara hei whakarato i te ngaohiko me te iahiko e ranea ana hei whakahaere i ngā taputapu i te wā e motu ana te hiko.
4. Ngā Ara Hiko: I roto i te maha o ngā ara hiko, ka whakakotahihia ngā pūtake ngaohiko rerekē hei whiwhi i te ngaohiko whakahaere e hiahiatia ana e ngā wāhanga hiko.
Ngā Wero i roto i ngā Pūtake Ngaohiko Whakakotahi
Ehara i te mea ngāwari te whakakotahi i ngā pūtake hiko i ngā wā katoa, ā, he maha ngā wero ka pā mai, tae atu ki:
1. Te Tauritekore o te Ngaohiko me te Iahiko: Me hototahi te ngaohiko me te iahiko o ngā pūtake ngaohiko kua whakakotahitia. Ki te kore, ka puta he tauritekore, ka heke te mahi, ka pakaru rānei ngā pūtake ngaohiko.
2. Te Whakahaere Wera: Mā te whakakotahi i ngā pūtake hiko, inā koa he nui, ka nui rawa te wera. Me whakahaere tika te wera hei ārai i te wera nui me te kino o ngā wāhanga.
3. Te Tohatoha Kawenga Kāore i te Taurite: I roto i te whirihoranga whakarara, ka taea e te tohatoha auhiko kāore i te ōrite i waenga i ngā pūtake ngaohiko te whakararu i ētahi pūtake. Me whakarite tika kia taurite te tohatoha kawenga.
4. Te Uaua o te Hoahoa Ara iahiko: Me whai whakamahere me te hoahoa tupato te whakakotahi i ngā pūtake ngaohiko i roto i ngā whirihoranga uaua. Ka taea e ngā hapa i roto i te hoahoa te arahi ki te rahunga o te pūnaha, te iti rānei o te whai huatanga.
Tauira o te Tātaitanga Pūtake Ngaohiko Whakakotahi
Hei homai i tētahi tirohanga mārama ake mō te whakakotahi i ngā pūtake ngaohiko, anei ētahi tauira tātaitanga.
Tauira 1: Te Hononga i ngā Pūhiko i roto i te Raupapa
Me kī, e toru ā tātou pākahiko, he 1.5V te ngaohiko o ia pākahiko. Mēnā ka honoa raupapatia, ko te ngaohiko katoa ko:
\[ V_{\text{tapeke}} = V_1 + V_2 + V_3 \]
\[ V_{\kuputuhi{katoa}} = 1.5V + 1.5V + 1.5V \]
\[ V_{\kuputuhi{katoa}} = 4.5V \]
Tauira 2: Te Hononga i ngā Pūhiko i te Whakarara
Me kī, e toru ā tātou pākahiko, he 1.5V te ngaohiko o ia pākahiko, ā, he 2A te iahiko. Mēnā ka honoa ngātahitia ēnei pākahiko, ka noho tonu te ngaohiko katoa ki te 1.5V, engari ko te iahiko katoa ko:
\[ I_{\text{tapeke}} = I_1 + I_2 + I_3 \]
\[ I_{\text{tapeke}} = 2A + 2A + 2A \]
\[ I_{\text{tapeke}} = 6A \]
Tauira 3: Huinga Raupapa me te Huinga Whakarara
Me kī e ono ā tātou pākahiko, ko te kaha o ia pākahiko he 1.5V, ko te kaha o te pākahiko he 2A. E hiahia ana tātou ki te hono i ngā pākahiko e toru kia raupapa kia nui ake te ngaohiko, kātahi ka hono i ngā huinga pākahiko e rua kia whakarara kia nui ake te iahiko.
– Te hono i ngā pākahiko e toru i roto i te raupapa:
\[ V_{\text{raupapa}} = 1.5V + 1.5V + 1.5V = 4.5V \]
\[ I_{\text{raupapa}} = 2A \]
– Te hono i ngā huinga pākahiko e rua i roto i te raupapa me te whakarara:
\[ V_{\text{tapeke}} = V_{\text{raupapa}} = 4.5V \]
\[ I_{\text{tapeke}} = I_{\text{raupapa}} + I_{\text{raupapa}} = 2A + 2A = 4A \]
Whakamutunga
He tikanga nui te whakakotahitanga pūtake hiko hei whakatutuki i ngā whakaritenga hiko i roto i ngā momo tono. Mā te whakakotahi i ngā pūtake hiko i roto i te raupapa, i te whakarara rānei, ka taea e tātou te whakatutuki i te hiko me te iahiko e hiahiatia ana e ai ki ngā whakaritenga o te pūnaha. Heoi, he wero anō hoki te whakakotahitanga pūtake hiko e hiahia ana kia aro nui ki a ia, pērā i te whakahaere wera me te tohatoha kawenga ōrite. He mea nui te māramatanga pai ki ngā mātāpono taketake me ngā tātaitanga tika mō te hoahoa i ngā pūnaha whai hua me te pono. Nō reira, kei te noho tonu te whakakotahitanga pūtake hiko hei wāhanga nui o te maha o ngā tono hangarau me ngā tono ahumahi.
