Kev siv hluav taws xob AC tswj tau tuaj yeem faib dav rau hauv tsib pawg hauv qab no.
(1) ferromagnetic resonant AC voltage regulator: kev siv saturated choke thiab sib xyaw ua ke ntawm capacitors nrog qhov tsis tu ncua voltage volt-ampere yam ntxwv thiab ua los ntawm AC voltage regulator. Sib nqus saturation hom yog cov qauv tsim thaum ntxov ntawm cov regulator. Nws yog ib qho yooj yim qauv, yooj yim rau siv, lub input voltage tso cai rau ib tug ntau yam ntawm cov kev hloov, txhim khu kev qha, muaj zog overload muaj peev xwm. Tab sis lub waveform distortion yog loj, stability tsis siab. Nyob rau hauv xyoo tas los no, txoj kev loj hlob ntawm voltage regulator transformer, kuj nrog kev pab los ntawm non-linear electromagnetic Cheebtsam kom ua tiav cov hauj lwm ntawm voltage regulator fais fab mov ntaus ntawv. Nws yog qhov sib txawv ntawm qhov sib nqus saturation regulator yog daim ntawv ntawm cov qauv sib nqus, thiab cov hauv paus ntsiab lus ntawm kev ua haujlwm yog tib yam. Nws yog nyob rau hauv ib tug tub ntxhais nyob rau tib lub sij hawm kom ua tau raws li cov kev cai voltage thiab voltage ob chav muaj nuj nqi, yog li nws yog zoo dua li qub zog transformers thiab sib nqus saturation regulator.
Sib nqus amplifier hom AC voltage regulator: lub magnetic amplifier thiab autotransformer txuas nrog nyob rau hauv series, thiab hluav taws xob Circuit Court yog siv los hloov lub impedance ntawm lub magnetic amplifier kom stabilize cov zis voltage. Nws daim ntawv Circuit Court tuaj yeem yog linear amplification, tseem tuaj yeem ua pulse width modulation, thiab lwm yam.. Hom kev tswj hwm no nrog kev tawm tswv yim tswj kev kaw lub voj kaw, yog li kev ruaj ntseg siab, cov zis waveform yog qhov zoo. Txawm li cas los xij, vim yog siv cov khoom sib nqus amplifiers nrog cov inertia loj, yog li lub sijhawm rov qab tau ntev dua. Thiab vim yog kev siv autocoupling, yog li kev tiv thaiv kev cuam tshuam tsis zoo.
③ zawv zawg AC voltage regulator: hloov txoj hauj lwm ntawm zawv zawg sib cuag ntawm lub transformer, thiaj li hais tias cov zis voltage kom tau ib tug ruaj khov ntaus ntawv, uas yog, tsav los ntawm ib tug servo lub cev muaj zog tsis siv neeg voltage regulator AC regulator. Cov regulators no muaj kev ua haujlwm siab, zoo tso zis voltage waveform, tsis muaj tshwj xeeb yuav tsum tau ntawm lub load. Tab sis qhov ruaj khov yog qis dua, lub sijhawm rov qab ntev dua.
Induction AC voltage regulator: los ntawm kev hloov cov theem sib txawv ntawm qhov nruab nrab voltage ntawm lub transformer thiab cov thawj voltage, cov zis AC voltage yog stabilized. Nws zoo ib yam li cov hlau-qhov txhab asynchronous lub cev muaj zog hauv cov qauv, thiab lub hauv paus ntsiab lus zoo ib yam li induction regulator. Nws qhov voltage stabilization ntau yog dav, qhov tso zis voltage waveform yog qhov zoo, thiab lub zog tuaj yeem yog ntau pua kilowatts. Tab sis vim hais tias lub rotor feem ntau nyob rau hauv lub xeev thaiv, yog li lub hwj chim noj yog loj, tsis muaj efficiency. Lwm cov tooj liab, hlau cov ntaub ntawv, yog li tsawg ntau lawm.
⑤ Thyristor AC voltage regulator: AC voltage regulator nrog thyristor raws li lub zog hloov lub caij. Nws muaj qhov zoo ntawm kev ruaj ntseg siab, teb ceev ceev, tsis muaj suab nrov. Tab sis vim yog cov khoom siv hluav taws xob ua kom puas tsuaj rau cov khoom siv sib txuas lus thiab cov khoom siv hluav taws xob ua rau muaj kev cuam tshuam.
