He hiko taahiraa-ake pai-mohiotia ...

Ia wāhi he ona ake hangarau pūrere rongonui, titiro i te hunga tino mohio ki ta, te wahi, pehea. Rere - ko te moana, parahutihuti, kaipuke. Hurirere - rererangi, rererangi, wira - pahikara, car, me ētahi atu A e kore matou e whakaata tonu i runga i te meka e kotahi enei whakaaro pērā inaianei ohie, me te mārama i muri, i ētahi wā taahiraa uaua i roto i te whanaketanga o te peka katoa o te engineering engineering aunoa ranei.

he hītori peheé, me te māngai o te engineering hiko pai-mohiotia - hiko. I roto i te kua tawhiti 1831 tomo Faraday te hītori o te kitea o te whakaurutanga hiko - te taketake parau tumu o te mahi o te hiko. i muri anake 45 nga tau, i homai pūtaiao Russian PN Yablochkov he ārai mo te tenenga o te hiko. Ko te rua E kei coils i tuwhera matua, whakapumautia te taea ki te taui i, e ko, tahuri, whakarerekē ngā me ngaohiko. Ko te rawa tuatahi i hanga ake hiko. transformers Modern whai āhuatanga o te whare o te maha patunga ki te hua iti he iti iho i te 1 cm, me to ratou production - ko te peka ārahi o te ahumahi hiko.

whakamahia te tikanga kei te he maha nui o transformers o take rerekē me ia he ona ake ingoa motuhake. Hei tauira, te whakamahi whānui o hiko he taahiraa-ake ngaohiko hiko, i te mea i te ngaohiko whakaputa o te maha kilovolts ko te ngaohiko supply o 220 V.

Ko te kupu, ko te hiko - he aha te mea te reira? Ko te whakamāramatanga matarohia ko e whai ake: Transformer - ko te mīhini hiko e tahuri te wāhi pūtake te mana o nāianei ki te tuarua awhiowhio ki te ngaohiko rerekē. E whakahaerehia ana te hiko ki te ngaohiko AC, no te mea kite pānga arataki te anake, no te te mara hiko. Te whakawhiti (huringa) o te pūngao e tika ana i te faafariuraa o te pūngao hiko i roto i te kopiko i te papa autō tuatahi, a ka atu - he whakawhitinga hoki ki te pūngao o nāianei hiko, engari i roto i te tuarua awhiowhio te. Ki te nui ake te tuarua awhiowhio i runga i te maha o hohoko te tuatahi, to tatou he hiko taahiraa-ake, me te mea te hono koe i te kopiko i runga i te anga ke, ka waiho i te hiko "te ritenga" - whakaiti.

Tera pea e hiahia ana koutou i roto i te karati, e kua he whatunga 36V hiko, te hono i te pikaunga hiko, pērā i tohutohutia akkamuljatora kōwae powered 220 - he take angamaheni i roto i te tikanga ki te tono i te hiko taahiraa-ake. Ko te otinga o tenei raruraru, whakaaro tatou hikoinga mahi.

ka tango 1. rihi Power i te uruwhenua - tino pea ka waiho reira te tahi mea rite 100 Watts. Ite e Me nga wa katoa ki te whai i te taha mo te heke mai, me te i roto i te tirohanga o te tōtika o te hiko o e pā ana ki 0.9, te kaha riro o te 150W awhiowhio te tuatahi ake nei.

2. Tīpakohia te ioka. Ko reira māmā ki te whakahaere i te matua autō e-āhua (te TV tawhito). Ka taea e tatou te whakamahi i tetahi, nei ripeka wāhanga he iti atu tohu i te hononga: P 1 = S * S / 1,44, te wahi P1 me S - te mana hiko i roto i Watts me te matua ripeka-wāhanga i roto i te tapawha cm. Ko te tātai homai he uara o S = 10,2 cm2.

3. Ko te nui tino i te "hanga" o te hiko te mahi i muri mai - e takoto e te maha o hohoko i runga i 1B: N = 50 / S = 50 / 10.2 = 4.9 hohoko / i roto i. Na e mea ohie ki te tātai i te maha o hohoko (ranei, rite "awhiowhio te kōrero"), kopiko tuatahi me te tuarua: W1 = 36 * N = 176 hohoko ko W2 = 220 * 5 = 1078 hohoko.

4. Whakatautuhia te ngā awhiowhio te. mana'o tatou e te mana o ia o nga kopiko o e pā ana ki 150 Watts. I roto i tenei take, whakahaere kopiko nāianei: J1 = 150/36 = 4,2A me J2 = 150/220 = 0,7A.

5. Na i koe nga raraunga katoa ki te whakatau i nga diameters o nga waea o nga kopiko. Ka meatia e matou pera: hoki te d1 pōkai tuatahi = 0.8 * √J1 = 0.8 * 2,05 = 1,64mm sq. ;

rite hoki te d2 awhiowhio te tuarua = 0.8 * √J2 = 0.8 * 0,84 = 0,67 mm tapawha.

Awhiowhio te coils tīpako diameters e haere mai ana i te paerewa.

Mea katoa! Ko runga i te tātai, engari ka taea e hua i te hiko taahiraa-ake me o ratou ringa? Ka rite ki te mea ratou - i reira he mea māmā, ki te hiahiatia kino. Ko te hiahia tūturu - ko reira te diy kaha taraiwa matua, kia e atu kakau, kakau.

6. Hanga e rua tinana i runga i te ara iahiko autō tīpakohia.

maru ia i te tāpae 7. papa mātotoru kei te taha o te hawhe tuatahi awhiowhio a tutakina glass- reira whakamohinu ranei.

8. muri, tāpae i runga i te papa kotahi e te hawhe te tuarua awhiowhio a hoki hipokina ratou whakamohinu.

9. Ko te whakaminenga o te ara iahiko autō, wāhanga coupler ioka - te raruraru e kore he tino uaua. I roto i huihui i te haurua matua autō he minaminatia ki te amuiraa i tetahi hanganga whakamahi ferroporoshka - ka tutakina tenei "i Ingarangi" o te pūrere i roto i te mahi.

Ko te reira! To tatou te kāinga-hanga, e kore e tatou whakaaro e mahi mo te wa roa, me te hari. Na ko wai e ruarua!
