Motor-wāhanga e toru i roto i te whatunga kotahi-wāhanga. nekeneke waea wāhanga

He āhuatanga i roto i te ora, ina e hiahia ana koe ki te whakauru i etahi ahua o te taputapu ahumahi i roto i te supply mains kāinga noa. Na i reira ko te raruraru ki te maha o waea. I mihini hangaia mō te mahi i roto i te tipu, terminals, te tikanga e toru, a ētahi wā wha, a. Aha ki te mahi ki a ratou, te wahi ki te te hono a ratou? Ko te hunga e tamata ki tamata kōwhiringa rerekē, kia e kore nga motors e hiahia noa ki te miro. He ara taea ki te hono i te kotahi-wā e toru-wāhanga nekeneke? Ae, ka taea e koe te whakatutuki i te hurihanga. Meapango, i roto i tenei take, ka hinga i te kaha te taniwha, e tata te hawhe, engari i roto i te tahi mau āhuatanga ko reira - anake te ara i roto i.

Ngaohiko whatunga toru-wāhanga, me o ratou ōwehenga

I roto i te tikanga ki te mahino e founga ki te hono i te pūkaha e toru-wāhanga ki te putanga tikanga, kia matau koutou e founga ki te pā ki te ngaohiko i roto i te whatunga ahumahi. E pai mohiotia uara ngaohiko - 220 me 380 volts. I mua, ko tonu 127 reira, engari i roto i te rima tekau o tenei kōwhiringa i whakarerea i roto i manakohia o atu tiketike. Hea i enei "tau makutu"? He aha e kore 100 ranei 200, ranei 300? Te āhua ki te kia māmā ki tau a tawhio ki te whakaaro.

Te nuinga o te taputapu ahumahi hiko te hangaia mo te hononga ki te toru-wāhanga tauutuutu nāianei. Ko te ngaohiko o ia wāhanga ki te waea kūpapa ko 220 volts, rite noa i runga i tou putanga kāinga. i haere mai hea i 380? Ko reira ngāwari nui ki te whakaaro i te tapatoru waerite ki koki o 60, 30 me te 30 nga nekehanga, i te mea he hoahoa pere o ngaohiko. Ko rite ki te roa o te huha, whakanuia e cos 30 ° te roa o te taha roa. I muri i taea te kite i tātai ohie e 220 x cos 30 ° = 380.

wāhanga nekeneke taputapu

E kore e taea te whakahaeretia ngā momo katoa o motors ahumahi i te wā kotahi. Ko te noa tino o ratou - te "workhorses" e hanga ake te nuinga o mihini hiko i roto i tetahi hinonga - mīhini tukutahingakore ki te kaha o te 1 - 1.5 kVA. Nahea te he pūkaha e toru-wāhanga i roto i ngā pūnaha e toru-wāhanga, hoki nei te tikanga reira?

Ko te ihi o tenei pūrere pāhoro ko te pūtaiao Russian Mikhail Dolivo-Dobrovolsky. Tenei hiko tino ko te kaitautoko o te ariā o mains toru-wāhanga, i roto i to tatou wa riro nei kua tino. Tukutahingakore nekeneke ngā wāhanga mahi e arataki i te kopiko stator i runga i nga conductors rotor e katia. Ka rite ki te hua o to ratou takanga o te kopiko poto-circuited i roto i ia o nei i reira ko te papa autō e pähekoheko ki te rārangi mana stator. Ko te kupu whiwhi taipana, ārahi ki te nekehanga porohita o te tuaka nekeneke.

Kua whakaritea e te kopiko i te koki o 120 °, reira tītaka mara whakaputaina e ia o nga wāhanga raupapa pana ia taha magnetizable o te rotor.

He tapatoru te whetū ranei?

-Wāhanga E toru nekeneke i roto i ngā pūnaha e toru-wāhanga taea te whakawhiti i runga i roto i te ara e rua - ki te kūpapa ranei kahore ia. huaina te tikanga tuatahi te "whetu" i roto i tenei take, ko ia o te kopiko i roto i te wāhanga ngaohiko (wāhanga kore) rite i roto i to tatou tikanga o 220 V. Wiring tā "tapatoru"-wāhanga e toru pūkaha he hononga raupapa o toru kopiko me aho supply (380) te ngaohiko puta noa i te kōpuku whakawhitinga. I roto i te take tuarua, ka hua nui i pā ana ki te hawhe o te mana o te nekeneke.

Me pēhea te ki te tahuri i runga i te pūkaha i roto i te huarahi i te ritenga?

kia fakahu'unga Mana e toru-wāhanga nekeneke he huringa i roto i te ahunga o te hurihanga i roto i te ritenga atu, arā whakataka. Ki te mahi i tenei, Me tika koe ki te hurihia te waea e rua o te toru.

Hoki te haratau, te huringa aronuinga i roto i te pouaka motor kāpeka e whakaratohia whare pungawerewere, hanga te tikanga o te parahi. Hei tahuri i runga i te "whetu" ata hono tahi nga waea putanga e toru o nga kopiko. "Triangle" whiwhi he iti ake uaua, engari ano hoki e taea te hapai i te reira i tetahi tohu tuarua hiko.

Wāhanga-nuku kaha

Na, i ētahi wā whakatika te pātai, me pehea ki te hono i te pūkaha e toru-wāhanga i roto i te putanga kāinga tikanga. Ki te koe tamata tika ki te hono atu ki te mono e rua waea, e kore e huri i te reira. I roto i te tikanga ki te tiki mahi, he mea e tika ana ki te whakatau i te wā neke ngaohiko tīpakongia i etahi koki (pai 120 °). Hei whakatutuki i tenei pānga, ka taea e koe, ki te tono koe i te huānga wāhanga-neke. Takahi kia me te hiko, a tae noa ātete, engari maha nekeneke e toru-wāhanga i roto i te whatunga wāhanga kotahi kua whakahohe whakamahi hiko tenei te puritanga (pūnga), tuku ki roto i te reta Latin C. Ngā Aronui

No nia i tono o awhi nei, he uaua ki te whakatau tika ki te whīwhiwhi o ratou uara (ki te kore e tohua ai i runga i te pūrere). Ki te whanganga i rahi L hiahiatia he pūrere motuhake kohia hoki tenei kaupapa ranei. I tua atu, i te kōwhiringa o awhi nei e wātea ana e te nuinga o whāiti. Heoi, ka taea e tetahi huānga wāhanga-neke whakamātau tiki ake, engari ko te reira raruraru.

Eaha te tupu no te tahuri te te pūkaha i? I tetahi o nga ngā hononga whangai te kore, i runga i te tahi atu - te kapenga, me te tuatoru - he tetahi ngaohiko neke e te tetahi koki ki te faatura ki wāhanga. Mārama me te mātanga-kore e kore e e kia oti ki te faatura ki te mana take aunoa te mahi pūkaha, engari i roto i ētahi wā ko reira rawaka hurihanga o te meka. Heoi, i te whakaoho kia ara ake ētahi raruraru pērā i te ngaro o ngā tīmatanga, ahei ki te neke i te rotor i ratou torona. Aha ki te mahi i roto i tenei take?

te pūnga tīmatanga

I te wa o te take tīmatanga-ake atu mau tautooraa e hiahiatia ana ki te hinga i te ope o te tūpuku me waku pateko. Hei whakanui i te taipana, he mea e tika ana ki te tāuta i tētahi pūnga atu hono ki te ara iahiko anake i te tīmatanga, ka kē atu. Hoki enei take, te kōwhiringa pai ko ki te whakamahi i te tūranga pushbutton kati. whakaaturia waea hoahoa mō te toru-wāhanga nekeneke ki te pūnga tīmata te raro, he reira ohie, me te māmā. I te wa o te tono ngaohiko e pāwhiri i runga i te pātene "Tīmata", ka tīmata pūnga ka hanga atu neke wāhanga. I muri i te pūkaha untwisted ki te pātene tere e hiahiatia ana, e koe e taea e (a kia) kia haere, a ka noho noa kaha e mahi i roto i te ara iahiko.

Tātaitanga o nga uara te puritanga

Na, ka kitea e matou e roto i te tikanga ki te taea te nekeneke e toru-wāhanga i roto i te whatunga kotahi-wāhanga rapu atu hoahoa waea i roto i nei, i roto i te tua ki te pātene tīmatanga, ngā rua pūnga iahiko. Me ratou ki mohio te uara, te kore e kore e te pūnaha mahi. Hei timata ki tautuhi tatou uara te puritanga hiko hiahiatia ki te faahepo i te rotor ki te wahia atu. Tūhono i roto i te whakarara ko reira te moni o:

C = Hk + Cp, te wahi:

v C - tīmata atu te puritanga switchable i muri i te wakarererangi;

C p - te pūnga mahi, e whakarato ana te hurihanga.

Otiia e hiahia ana matou i te uara o te n ahau nāianei tauanga (te e rārangi reira i runga i te tapanga piri ki te pūkaha i te wheketere). taea hoki te takoto tenei tawhā whakamahi tātai māmā:

Ahau N = P / (3 x U), i reira:

U - te ngaohiko i honotanga "whetu" - 220, a ki te te "tapatoru", te 380 V;

P - te mana e toru-wāhanga nekeneke, he reira te tahi mau taime i roto i te take o te mate o whakatū papa whakaritea e te kanohi.

Na, i runga i te mana whakahaere e hiahiatia ana rānei tatau e:

CP = CP = 2800 N ahau / U - no te "Star";

C p = 4800 N ahau / U - no te "tapatoru";

Tīmata pūnga Me nui atu te mahi o 2-3. Unit o mehua - microfarad.

He ara tino tino māmā ki te tātai i te puritanga: C = P / 10, engari homai tenei tātai nga tau kia kaua ki te tona uara. Heoi, te takirimatia te i roto i tetahi take he mea e tika ana.

Aha Me whakatikatikanga

Ko te tikanga o te tātaitanga i runga he whakatau tata. Tuatahi, ko te uara ränei i runga i te whare o te kaha hiko kia rerekē nui i te tūturu. Tuarua, pūnga iahiko pepa (te tikanga e korero ana, he mea e kore e cheap) te whakamahia pinepine te rua ringa, a he ana ratou katoa o te tahi atu taonga, i raro ki te hoholo, e arata'i deflection ki ara nui o mea tawhā. Te toru, te nāianei e ka pau e te pūkaha tei runga i te kawenga mīhini i runga i te take, a koia anake e taea te arotake i te reira experimentally. Me pēhea te ki te mahi i te reira?

ka rapua e te reira i te moka o te manawanui. Ka taea e te hua e huinga rawa whakaemi o ngā pūnga hono i roto i whakarara, me te i roto i te raupapa. Ko te mea matua - i muri ki te mahi pai katoa whakatika, kia rite kore ki te taka atu i nga pito soldered o nga wiri ahu i te pūkaha. A reira ka kore kino anō-uiui i nga hua, me te pea ki te faaohie i te hoahoa.

Te tuhi ake o nga ipu pūhiko

Ki te te tikanga o nga rangatira he kahore nohinohi -hiko motuhake, e taea ana ki te ine i nāianei ki waho whawhati i nga mekameka, he mea e tika ana ki te hono i te iahiko i roto i te raupapa ki ia waea, ngā nei i roto i te pūkaha e toru-wāhanga. I roto i te whatunga kotahi-wā ka rere uara tapeke, me te kōwhiringa o ngā pūnga kia feinga mo nga coils utanga tino ōrite. Kia mahara te reira e ka heke daisy te puritanga katoa rite ki te ture:

1 / C = 1 / C1 + 1 / C2 ... a na i runga i, a i roto i te whakarara - i runga i te anga ke, whakawhanake reira.

Ano, e kore me wareware koe e pā ana ki taua tawhā nui rite te ngaohiko i runga i te pūnga tātai te. e kore e waiho te reira i iti iho i te uara ränei o te whatunga, a he pai ki te rāhui.

iahiko rere

wāhanga Scheme motor hono i waenganui i tetahi wāhanga me te kaiwhakahaere kūpapa, i ētahi wā tāpiri resistance. tavini te reira ki te whakarite kia tiaki i te pūnga tīmata kore e putu toe i muri i te mīhini kua tahuri atu. Ka taea e tēnei pūngao meinga ru hiko, e kore e kino, engari rawa kino. I roto i te tikanga ki te kia haumaru, kia kia whakarara ki te puritanga tīmata ki te hono i te parenga iahiko (y hiko e huaina "whakanekeneke"). Ko te uara o ona resistance nui - i te hawhe ki Meg Meg, ka he iti, kia pretty me te mana poluvattnoy te rahi o te reira. Heoi, ki te kore ia e wehi ki te kia "timonga", e kahore tenei taipitopito Ko te tino taea ki te mahi i te kaiwhakamahi.

Mā te electrolytes

Ka rite ki kua tuhia, ki te kiriata pepa ranei capacitances utu hoko, a kahore e ratou rite ohie rite e hiahia ana tatou. Ka taea e koe te whakaputa i te hononga kotahi-wāhanga o motors e toru-wāhanga mā te whakamahi i ngā pūnga -hiko inexpensive me wātea. I roto i tenei take, nui atu iti, ratou ano e kore e, rite ki te tu atu ki te 300 volts DC. No te take haumaru, kia kia shunted ratou ngōhiko Semiconductor (D 245 ko D 248, hei tauira), engari ko te reira pai ki te mahara e whiwhi i te ngaohiko tauutuutu ki te kawehiko, me te tuatahi kaha wera i te reira ki runga i te kătahi o enei whakaaro, ka ka pahū, nui, me te mīharo te. Na reira, kore e tino āhei, he reira pai ki te whakamahi i te pūnga iahiko momo pepa taua, ko te iti rawa tamau, ahakoa tāupe te ngaohiko. Ētahi rangatira tukua rawa te whakamahi o electrolytes i roto i te ara iahiko tīmata. Nā ki te rongo wā-poto ki te ngaohiko tauutuutu, e kore ai ratou e whai wa ki te pahū. He pai kore ki te whakamātau.

Ki te mea i reira e kore pūnga iahiko

Hea tangata noa e kore e nei whai wāhi ki te wahi hiko, me te hiko pai-hoko, hoko ratou? I ngā mākete puruhi, me te "hokohoko puruhi". He ratou, tiaki vypayat o te tangata (te tikanga ruhiruhia) ringa o mīhini horoi tawhito, televisions me ētahi atu tūemi whakaputaina o whare me te whare, me te hangarau ahumahi. Te aniraa i hoki enei hua Soviet rota production: e mohio ana kaihoko e ki he tika te tūemi, ka hoko i te reira, a ki te kahore - a kore e tango i te mea homai noa. tupu te reira i e tika nga matea whanau (i roto i tenei take i te pūnga) he kore noa. Na te aha e koe te mahi i? kore e mea faufaa te reira! Heke me parenga, anake e hiahia ana kaha, pai uku me vitrified. O te akoranga, e kore e te pai ātete (kaha) wāhanga nuku, engari kahore i roto i tenei ao e kore he tino, a i roto i tenei take, ko te reira pai. Katoa te tinana tinana he-hiko whaiaro, kaha hiko me te resistivity, kia reira he otaota iti o te puehu i te maunga nui ranei. Tahuri te pūkaha e toru-wāhanga i roto i te turanga riro taea mā te whakakapi i te parenga ia pūnga i runga i te kaupapa i runga, te hāhi tatau nei i te tātai:

R = (0,86 x U) / ki, ai:

ki - te nui o te nāianei mō te hononga e toru-wāhanga, me;

U - to tatou taiva ore 220 volts.

He aha engines ka whakatata?

I mua i whiwhi koe i te rota o te motor moni e hiahia rangatira tupato ki te whakamahi i rite te puku mo te wira huri, kite porowhita, pēhia drill ranei atu tetahi pūrere kāinga whai hua e kore e kino ia ki te whakaaro e pā ana ki tona faaohiparaa mō tenei whakaaro. Ehara i te katoa ko te pūkaha e toru-wāhanga i roto i te supply wāhanga kotahi taea te mahi i te katoa. Hoki tauira, kia mukua te raupapa o MA (tona rotor kirera-whare herehere ki te whare herehere rua) kia rite kore ki te whai ki te lug kāinga he taimaha nui, me te memeha. I roto i te whānui, he reira pai ki te whakamātau tuatahi, ranei fakaafe'i he tangata mātanga, hiko, hei tauira, me ki kōrero ki a ratou i mua i te hoko koe. Tino pai e toru-wāhanga tukutahingakore raupapa nekeneke UAD, APN, AO2, kamupene tahi-take, me te, o te akoranga, me te A. enei waehere tohua i runga i te nameplate.
