Kia pehea te ko te tātaitanga o te kawenga hiko

I mua i puta ki te hoahoa o Electrics i roto i tou whare, fare, whare, me tuatahi hanga koe i te kaupapa tatauranga, ka e kia whakarārangitia te kawenga tūmanakohia katoa i runga i te whare, me te te roa o nga wāhanga takitahi o te taura. Hei whakaputa i te kāri taua a ka hiahia koe ki te tātai i te kawenga hiko. taiawhio hiko tika titoa o te ahanoa ka tangohia ake nga waea me taura e hiahiatia ana ngā wāhanga. I roto i te wā i reira te taura ripeka-wāhanga iti iho i te e hiahiatia ana mō te taumahinga noa o engines tīmata te mana nui taura ki te overheat. A, ka rite ki te putanga ko te whakangaromanga o te mātao. Ka rite ki te hua, kei te tino heke te roanga o te mahi me te tika o te apa waea. Ano, Ka taea e te taura pukā meinga te ahi. tino maha, ka whakamahia kaimahi (ki te whakaora) te āhuatanga e rite puta wāhanga waea, he iti iho i te hiahiatia. Ko te hua ko te taiawhio poto me te ahi. Kia kite a, he aha te mea te tātaitanga o te kawenga hiko.

Ko te kōwhiringa tika o te whakawhiti whakaaro, me te taura ripeka-wāhanga tei runga i te uara rerekē o ngā tawhā o whatunga hiko. Ko te nui tino o ratou ko te nāianei hiko kawenga. I te wā hoahoa taea te whakaritea te nui tohua tikanga anake pāngarau. Kei te whakaaro te reira i te tātai rawa nui o pikaunga hiko i roto i te whatunga toru-wāhanga, rite kia he kawenga o ratou kia whakanohoia whakanoho i roto i te wāhanga, ki te karo i distortions o ngaohiko. Heoi, i roto i te whatunga kāinga kia kawea taua tātaitanga i roto i roto i te hoahoa o te whakangungu rakau e kore anake engari noho ano hoki.

kawea tātai kawenga hiko te roto mō ngā uara o mōhiotia mana hiko whakaaro, te āhua o nga pikaunga, me te ngaohiko mains. tātai whakamahia mō te whakatau i te nāianei kawenga mō whatunga kotahi-wāhanga: ahau = P / (U × cosφ), i reira:

• U - te uara tūturu o te ngaohiko supply (whanganga i volts);
• cosφ - hāngai tauwehe mana.

Hoki whatunga toru-wā kawea te tātai o pikaunga hiko i roto i rite ki te tātai e whai ake nei: ahau = P / (1,73 × U × cosφ).

Tei runga i te āhua o te kawenga uara mana tauwehe tīpakohia te. I roto i te tātaitanga i te kawenga urupare o te mana teitei (awhi nei rama, motors hiko, transformers me ētahi atu fehokotakianga.) Uara Toharite tangohia cosφ = 0.8. I roto i te whakatau i te mana o nāianei hoki te kawenga hohe (huānga whakamahana, aano atu rama) take mana āhua rite ki te kotahi. Heoi, i tetahi kawenga parenga tonu he reira wähanga urupare, na hanga nga tātai whakamahi uara cosφ = 0,95.

I roto i te mutunga, haamana'o tatou e kore e hiko e muru hape, e kore e hoatu e te reira te rua tūponotanga. Haumaru me te tōtika o ngā pūnaha hiko - e te hiahia ki tetahi hiko ngaio. Na kahore he mea i reira mahi ai ia: i mahi ranei i roto i te rāngai tūmataiti. kawenga hiko - ko tetahi o te tawhā hoahoa tino nui e Me whakaaro i roto i tetahi pūnaha tenei.
