Thyristor amandla Regulator: umzobo umsebenzi siseko kunye nesicelo

Eli nqaku lichaza indlela yokusebenzisa umlawuli thyristor amandla, apho scheme iya kunikwa ngezantsi

Kubomi bemihla ngemihla kudla kakhulu eziyimfuneko ukulawula zombane igunya, ezifana cookers, intsimbi ngelotha, boilers kunye izifudumezi, izithuthi - isantya motor, njl Uncedo iza elula engahlawulwayo radio yoyilo - thyristor amandla Regulator. Hlanganisa isixhobo onjalo nzima, lube isixhobo yokuqala ekhaya-wenza ukuba uya kulenza lobushushu kwincam umsebenzi wolawulo ngelotha abo basandula kuqalisa radio engahlawulwayo. Kufuneka kuqatshelwe ukuba isikhululo ngelotha ogqityiweyo kunye ulawulo lobushushu, kunye nezinye iimpawu ezintle kakhulu ibiza ngaphezu kokuba intsimbi elula ngelotha. Le sethi isezantsi amacandelo likuvumela ukuba kwakhiwe thyristor elula amandla alawulayo-point kweentambo.

Ukuze ufumane iinkcukacha, kwakuxhomekeke ufakelo - indlela Wahlanganisa a macandelo radio-elektroniki ngaphandle kokusebenzisa ibhodi yesekethe eziprintiweyo, kunye nezakhono ezilungileyo, unako ngokukhawuleza bahlanganisane izixhobo ze-elektroniki ukuntsonkotha medium of.

Unako nokuyalela elektroniki umyili thyristor isilawuli, kwaye abo bafuna ukuqonda yonke ngokwakho, ngezantsi umzobo kunye wachaza umgaqo yokusebenza.

nabalawuli Scope thyristor

Phela, lo omnye-phase thyristor amandla Regulator. Loo sixhobo sinokusetyenziswa ukulawula amandla okanye inani yeenguqu. Nakuba kunjalo, kufuneka kuqala siqonde indlela umgaqo osebenza kuyo thyristor, kuba oko kuya kuvumela siqonde uhlobo umthwalo kubhetele ukuba usebenzise umlawuli.

wenza njani screen?

Thyristor - isixhobo semiconductor ezilawulwa ekwaziyo ukuqhuba ngoku kwicala elinye. Igama elithi "ezilawulwa" lisetyenziswa akukho ngozi, ngenxa yokuba ngayo, ngokwahlukileyo ukuya diode, nayo eli liyithweleyo zangoku kwi kwipali omnye kuphela, ungakhetha ixesha xa thyristor iqalisa ukuqhuba yangoku. Le thyristor has ezinjengeetheminali ezintathu:

• Anode.
• Cathode.
• Isango electrode.

Ukuze ukuba ngoku waqalisa flow ngalo thyristor, le miqathango ilandelayo kufuneka nazo: umba kufuneka ibe impahla e kwempixano, ukuba i electrode yokulawula kubonelelwa ukubetha uveza. Ngokungafaniyo transistor, ulawulo thyristor ayifuni ukugcinwa uphawu yolawulo. Kule ezincinane iphele: i thyristor masivalwe zokuphazamisa zangoku kuphela kwisekethe, okanye ekusekeni anode ombane reverse - cathode. Oku kuthetha ukuba ukusetyenziswa thyristors e DC le ngqo kakhulu yaye ngokufuthi vuphukuphuku, kodwa iziphaluka AC, umzekelo kwiphakati efana thyristor amandla komlawuli, isiphaluka sakhiwe ngendlela yokuba ukuqinisekisa ukuba imiqathango emayilandelwe xa kuvalwa. Ngalinye Kwisiqingatha amaza aya ukuvala thyristor ahambelanayo.

Wena mhlawumbi ukuqonda yonke into? Yenza ithemba - ngoku kuchazwa ngokweenkcukacha inkqubo esebenza isixhobo ogqityiweyo.

nabalawuli Scope thyristor

Kwezinye iisekethe ukusebenzisa ngempumelelo thyristor amandla Regulator? Le nkqubo ikuvumela ocoliweyo ukunyenyisa amandla izixhobo zokufudumeza, oko kukuthi, ukuba basebenze umthwalo resistive. Xa sisebenza kunye imithwalo ezenza kakhulu thyristors ukuze nje ayivaleki, oko kunokubangela umonakalo ukuya kwimveliso.

Ngaba kunokwenzeka ukuba alungise isantya injini?

Ndicinga ukuba abafundi abaninzi baye babona okanye wasebenzisa drill, angle screwdriver, nto leyo elidume obizwa ngokuba "Bulgarians", kunye nezinye izixhobo namandla. Usenokuba uye waphawula ukuba inani revolutions ixhomekeke ucinezela indlela isixhobo iqhosha-adubule. Apha kule ngxenye thyristor ehlanganisiweyo nje amandla Regulator (scheme siboniswa apha ngezantsi), nge apho inguqu kwinani yeenguqu.

Ziqapheleni! Thyristor ayikwazi ukutshintsha iinjini isantya induction. Ngoko ke, lo ombane umqokeleli hlengiswe kwinjini baxhotyiswe unit brush.

Driving thyristor amandla Regulator thyristors kunye ezimbini

scheme lohlobo ukuqokelela amandla thyristor ngezandla zabo kubonisiwe kulo mzobo ungezantsi.

, I ombane imveliso kule yesekethe volts-15 ukuya 215 kwimeko thyristors bathi ezinyuselwe olubi ubushushu gesi malunga 1 kW. Indlela switsha Ngokukhanya nokuvula umbane eziluzizi yenziwe kwesikim enjalo.

Ukuba awufuni ummiselo ombane ngokupheleleyo kwaye ufumane imveliso ngokwaneleyo ukusuka volts 110 ukuya 220, sebenzisa le umzobo obonisa enesiqingatha-wave thyristor igunya Regulator.

Zisebenza njani?

Iinkcukacha ezichazwe ngezantsi isebenziseka kwiisekethe ezininzi. Amagama Ileta iya kuthathwa ngokungqinelana yokuqala scheme thyristor isilawuli

Thyristor amandla komlawuli, umgaqo yayo isekelwe phezu ulawulo kwisigaba utshintsho ixabiso ombane kunye namandla. Lo mgaqo siyifumana yokuba kwiimeko eziqhelekileyo umthwalo umsinga nokuxuba ukusuka kumsebenzi womnatha lekhaya, iyahluka sinusoidally. Ngaphezu kwinkcazo umgaqo neyokusebenza thyristor, kwathiwa ukuba isixhobo nganye isebenza kwicala elinye, leyo ilawulwa bawo-nokulatyuza lencinibakazi sine. Kuthetha ukuthini?

Ukuba kuya kuba ngaphantsi kuba lombane (ixabiso olusebenzayo, leyo "ufumana" umthwalo) lingaphantsi kwe-network nge thyristor ukudibanisa ngamathuba umthwalo ngephanyazo echazwe kakuhle, ixabiso ombane RMS. Le meko kuboniswa kule grafu.

Le ndawo eyenziwe mnyama - oku indawo ukugogeka ubonakele phantsi komthwalo. Le leta "a" kwi iasi enqamlezileyo ibonisa kuvulwa thyristor. Xa isiphelo entle isiqingatha-yomtshangatshangiso uqale ixesha kunye ezimbi isiqingatha-yomtshangatshangiso otshangatshangisiweyo, omnye thyristors ivaliwe, kwaye ngexesha elinye evula thyristor yesibini.

Masiqonde ukuba isebenza njani thyristor amandla Regulator ethu

scheme lokuqala

Nquma kwangaphambili ukuba amazwi 'positive "yaye" ezimbi "ukuba kusetyenziswa" lokuqala "no" yesibini "(halfwave).

Ngoko ke, xa icebo lethu ukusebenza yokuqala isiqingatha-yomtshangatshangiso, ukuqalisa ukutshajisa umthamo C1 no-C2. Izinga kwentlawulo anqongophele ngenxa potentiometer R5. into esebenzayo iyaguquguquka, kwaye sebenzisa yona ukuba esekwe ombane kwimveliso. Xa C1 capacitor kubonakala kuyimfuneko ukuze lokuvula dynistor VS3 ombane dynistor ivula, ngoku yhuu therethrough, ngokusebenzisa evulekileyo thyristor VS1. Lo mzuzu yokuwa dynistor na indawo "a" kule grafu thaca kwicandelo angaphambili ale nqaku. Xa ombane udlula zero kwaye elijikeleza phantsi yesibini isiqingatha-yomtshangatshangiso, lo VS1 thyristor evaliwe kwaye le nkqubo iphindiwe kwakhona, kuphela dynistor yesibini, thyristor kunye ekondensa. Resistors R3 ne R3 asetyenziswa ukulawula umda yangoku, kunye R1 R2 - kuba circuit sinjalo thermal.

Umgaqo tyando uyafana yesibini scheme, kodwa iya kuphela kulawulo omnye besiqingatha njengamaza ombane nokuxuba. Ke kaloku, esazi umgaqo cebo, ungakwazi ukudibanisa okanye ukulungisa amandla thyristor ngezandla zabo.

Ukusetyenziswa komlawuli ekhaya kunye nokhuseleko

Asikwazi ukuba eli cebo ayiboneleli bodwa galvanic evela mbane, ngoko kukho umngcipheko ugesi. Oku kuthetha ukuba akazukuyibamba izandla control cruise. Kufuneka usebenzise ityala ekude. Kuyimfuneko ukuba bayile ulwakhiwo isixhobo sakho ukuze akwazi xa kunokwenzeka ukuba Wabugusha kwiphakati ilawulwa, fumana isihlalo esingenanto izindlu. Ukuba isixhobo elawulwa yi zokubhala, ngoko ngokubanzi iyavakala ukudibanisa kuyo nge utshintsho ukulawula ukukhanya ukukhanya. Le isisombululo ngokuyinxenye kusikhusela yabanjwa ugesi, uya kuphelisa imfuno yokuba lokufumana izindlu ezifanelekileyo, ine- imbonakalo enomtsalane futhi akhiwe indlela mveliso.
