Tukutahinga nekeneke - huapai me ngā huakore

riro te tino whānui e whakamahia ana te mīhini pērā i te pūkaha tukutahinga te i roto i te ahumahi te wahi i reira he rere hiko i te tere aumou. Hei tauira, compressors ki engines kaha, papua actuators. Ano, Ko te wāhanga, me taputapu whare maha he nekeneke tukutahinga, pērā i te mea i roto i haora.

Ko te parau tumu o te mahi o tenei mīhini Ko te tino māmā. Ko te pāhekoheko o te papa autō tītaka o te armature whakaputaina e te tauutuutu nāianei hanga mara, me te autō i runga i te amo pūpoapoa nāianei tamau ko te pūtake o te parau tumu o te mahi o te pūrere pērā i te pūkaha hiko tukutahinga. Tikanga, he pūpoapoa kei i runga i te rotor, me te punga - te stator. engines mano rite amo te whakamahi i electromagnets. Ko reira te mea he momo o te kaha-iti - he nekeneke tukutahinga ki aukume pūmau. Ko te rerekētanga matua i waenganui i ngā mīhini tukutahinga me tukutahingakore - stator me te hoahoa rotor.

Ki te whakatere i te pūkaha ki runga ki te taumata tere te tauanga maha whakamahi aratau tukutahingakore. I roto i tenei aratau, awhiowhio te poto-circuited te pūpoapoa. I muri i te pūkaha haere ki te tere tauanga, kaiwhakawhiwhi te rectifier DC pūpoapoa. Ka taea e anake tere iti nekeneke tukutahinga te mahi takitahi.

He maha ngā painga i te nekeneke taua. Ko ia he tikanga o te nui matatini atu mīhini tukutahingakore, engari wāhikē tenei e te maha o ngā painga. Ko tētahi o nga painga matua - tona kaha ki te mahi i waho te kai o te kaha urupare pānga ranei. Ko te kupu he rite ki te kotahitanga te take mana pūkaha. I raro i enei tikanga, he anake te pūkaha AC tukutahinga kaha wähanga whatunga kawenga. He pānga taha ko ki te whakaiti i te rahi te nekeneke (mo te nekeneke arataki, tatau te stator awhiowhio te me te ngā kaha, me te urupare i runga). Heoi, ka taea e te pūkaha tukutahinga whakaputa mana tūturu me urupare, whakahaere i roto i te aratau overexcitation.

Ko nui iti tairongo ki rerekē te nekeneke tukutahinga me makaka ngaohiko i roto i te whatunga. Ko te hunga i waka hiko i te ātete teitei ki overloads. taea ki te whakapiki ake i te āheinga kikī o te pūkaha e whakanui ake i te nāianei excitation. Ko hoki te painga ki te mīhini tukutahinga tamau tere hurihuri iti i tetahi kawenga (anake kikī).

Te feaa, he ona ake paruparu i te mīhini pērā i te nekeneke tukutahinga. E pā ana ratou ki utu tiketike, me te mahi uaua. Ko te raruraru matua ko te excitation o te pūkaha me tona whakataki ki synchronism. kitea tēnei wā exciters thyristor horapa, e whai he nui teitei tōtika, i te hoki tukumate hiko. Heoi, ko te nui teitei to ratou utu. Mā te whakamahi i te whakakā thyristor taea whakaoti maha ngā raruraru: te excitation ture tino pai o nāianei, tautoko whenu Phi uara tamau, te ngaohiko mana i runga i te tupare, te whakahaere i nga ngā stator me te rotor i roto i te aratau whawhati tata, a roto i te take o te kikī.
