Ndi chipangizo chamagetsi chomwe chimasintha ndikuwongolera voteji ya AC, ndipo mkati mwa voteji yomwe yatchulidwa, imatha kukhazikika voteji yomwe imachokera mkati mwamtundu womwe watchulidwa kudzera mu malamulo amagetsi.
Zofunika
Ngakhale pali mitundu yambiri ya owongolera ma voltage a AC, mfundo yoyendetsera dera lalikulu ndi yosiyana, koma kwenikweni (kupatula ma AC parameter voltage regulators) ndizomwe zimalowetsa ma switch sampling circuits, control circuits, voltage
1. Kusintha kolowera: Monga chosinthira chothandizira chamagetsi chokhazikika, chosinthira chamagetsi chaching'ono chokhala ndi chitetezo chocheperako chimagwiritsidwa ntchito nthawi zambiri.
Ma voltage stabilizer ndi zida zamagetsi zimagwira ntchito yoteteza.
2. Voltage yoyang'anira chipangizo: Ndi chipangizo chomwe chimatha kusintha mphamvu yamagetsi.Ikhoza kuonjezera kapena kuchepetsa mphamvu yamagetsi, yomwe ndi gawo lofunika kwambiri la stabilizer.
3. Sampling circuit: imazindikira mphamvu yotulutsa mphamvu ndi yomwe ilipo ya stabilizer yamagetsi, ndipo imatumiza kusintha kwa magetsi opangira magetsi.
4. Chipangizo choyendetsa galimoto: Popeza chizindikiro chamagetsi chowongolera cha dera lowongolera ndi chofooka, m'pofunika kugwiritsa ntchito chipangizo choyendetsa galimoto kuti chikulitse mphamvu ndi kutembenuka.
5. Chipangizo chotetezera galimoto: chipangizo chomwe chimagwirizanitsa ndikuchotsa zotulutsa za voltage stabilizer.Nthawi zambiri, ma relay kapena ma contactor kapena fuse amagwiritsidwa ntchito.
6. Dongosolo loyang'anira: Imasanthula sampuli yowunikira dera.Mphamvu yotulutsa ikakhala yayikulu, imatumiza chizindikiro chowongolera kuti muchepetse voteji ku chipangizo choyendetsa, ndipo chipangizo choyendetsa chimayendetsa chowongolera kuti chichepetse mphamvu.Mphamvu yamagetsi ikatsika, chizindikiro chowongolera voteji chimatumizidwa ku chipangizo choyendetsa, ndipo choyendetsa chimayendetsa chipangizo chowongolera voteji kuti chiwonjezeke voteji, kuti akhazikitse voteji kuti akwaniritse cholinga chokhazikika. .
Pamene wapezeka kuti linanena bungwe voteji kapena panopa ali kunja kwa ulamuliro osiyanasiyana owongolera.Dongosolo loyang'anira lidzawongolera chipangizo choteteza kutulutsa kuti chiteteze zida zamagetsi, pomwe chipangizo choteteza chiwongolero chimalumikizidwa ndi zomwe zimatuluka pansi pamikhalidwe yabwinobwino, ndipo zida zamagetsi zimatha kupeza magetsi okhazikika.
Gulu la makina
Chipangizo chamagetsi chomwe chingapereke mphamvu yokhazikika ya AC pa katundu.Imadziwikanso kuti AC voltage stabilizer.Pa magawo ndi zizindikiro zamtundu wamagetsi okhazikika a AC, chonde onani zamagetsi okhazikika a DC.Zida zosiyanasiyana zamagetsi zimafuna mphamvu yamagetsi ya AC yokhazikika, makamaka pamene luso lamakono la makompyuta likugwiritsidwa ntchito kumadera osiyanasiyana, mphamvu yachindunji yochokera ku gululi yamagetsi ya AC popanda kuchitapo kanthu sikungakwaniritse zosowazo.
Magetsi okhazikika a AC ali ndi ntchito zosiyanasiyana komanso mitundu yambiri, yomwe imatha kugawidwa m'mitundu isanu ndi umodzi yotsatira.
① Ferromagnetic resonance AC voltage stabilizer: Chipangizo cha AC voltage stabilizer chopangidwa ndi kuphatikiza kwa coil yodzaza ndi chokocho ndi capacitor yofananira yokhala ndi mawonekedwe a volt-ampere nthawi zonse.Maginito machulukidwe amtundu ndi momwe zimakhalira momwe zimakhalira zowongolera zamtunduwu.Ili ndi mawonekedwe osavuta, kupanga kosavuta, kusiyanasiyana kovomerezeka kosiyanasiyana kwamagetsi olowera, ntchito yodalirika komanso kuchulukira kwamphamvu.Koma kupotoza kwa waveform ndikokulirapo ndipo kukhazikika sikuli kwakukulu.Voltage stabilizer transformer yomwe yapangidwa posachedwapa ndi chipangizo chamagetsi chomwe chimazindikira kukhazikika kwamagetsi pogwiritsa ntchito kusagwirizana kwa zigawo za electromagnetic.Kusiyana kwake ndi maginito saturation regulator kuli kusiyana kwa kapangidwe ka maginito, ndipo mfundo yoyambira yogwirira ntchito ndiyofanana.Imazindikira ntchito ziwiri za kuwongolera voteji ndi kusintha kwamagetsi nthawi imodzi pachinthu chimodzi chachitsulo, motero imaposa zosinthira mphamvu wamba komanso zowongolera zamagetsi zamagetsi.
② Magnetic amplifier mtundu wa AC voltage stabilizer: chipangizo chomwe chimalumikiza maginito amplifier ndi autotransformer mndandanda, ndikugwiritsa ntchito dera lamagetsi kusintha kutsekeka kwa maginito amplifier kuti akhazikitse mphamvu yamagetsi.Mawonekedwe ake ozungulira amatha kukhala amplification amzere kapena kusinthasintha kwa pulse wide.Wowongolera wamtunduwu ali ndi dongosolo lotsekeka lokhala ndi mayankho, motero amakhala ndi kukhazikika kwakukulu komanso mawonekedwe abwino otuluka.Komabe, chifukwa chogwiritsa ntchito maginito amplifiers okhala ndi inertia yayikulu, nthawi yochira imakhala yayitali.Chifukwa cha njira yodzigwirizanitsa yokha, mphamvu yotsutsana ndi kusokoneza imakhala yochepa.
③Sliding AC voltage stabilizer: Chipangizo chomwe chimasintha malo olumikizirana ndi thiransifoma kuti akhazikitse voteji yomwe imatulutsa, ndiye kuti, voteji yomwe imayendetsa AC voltage stabilizer yoyendetsedwa ndi servo motor.Zowongolera zamtunduwu zimakhala ndi magwiridwe antchito apamwamba, mawonekedwe abwino otulutsa magetsi, ndipo palibe zofunikira zamtundu wa katunduyo.Koma kukhazikika kumakhala kochepa ndipo nthawi yochira ndi yayitali.
④ Inductive AC voltage stabilizer: chipangizo chomwe chimakhazikitsa voteji ya AC posintha kusiyana kwa gawo pakati pa voteji yachiwiri ya thiransifoma ndi magetsi oyambira.Ndilofanana ndi kapangidwe ka ma waya asynchronous motor, ndipo kwenikweni ndi ofanana ndi induction voltage regulator.Mitundu yake yoyendetsera magetsi ndi yayikulu, mawonekedwe amagetsi otulutsa ndi abwino, ndipo mphamvu imatha kufika mazana a kilowatts.Komabe, chifukwa rotor nthawi zambiri imatsekedwa, mphamvu yogwiritsira ntchito mphamvu imakhala yaikulu ndipo mphamvu zake zimakhala zochepa.Kuonjezera apo, chifukwa cha kuchuluka kwa zinthu zamkuwa ndi zitsulo, kupanga kochepa kumafunika.
⑤ Thyristor AC voltage stabilizer: AC voltage stabilizer yomwe imagwiritsa ntchito thyristor ngati chinthu chosinthira mphamvu.Zili ndi ubwino wokhazikika kwambiri, kuyankha mofulumira komanso popanda phokoso.Komabe, chifukwa cha kuwonongeka kwa mawonekedwe a mains waveform, zidzasokoneza zida zoyankhulirana ndi zida zamagetsi.
⑥ Relay AC voltage stabilizer: gwiritsani ntchito relay ngati AC voltage stabilizer kuti musinthe mafunde a autotransformer.Ili ndi maubwino osiyanasiyana owongolera ma voltage, kuthamanga kwachangu komanso mtengo wotsika wopanga.Amagwiritsidwa ntchito powunikira mumsewu komanso kugwiritsa ntchito kunyumba zakutali.
Ndi chitukuko chaukadaulo wamagetsi, mitundu itatu yotsatirayi yamagetsi okhazikika a AC idawonekera m'ma 1980.①Kulipiridwa kwa AC voltage stabilizer: komwe kumadziwikanso kuti pang'ono kusintha voteji stabilizer.Mphamvu yowonjezera ya transformer yamalipiro imagwirizanitsidwa mndandanda pakati pa magetsi ndi katundu.Ndi mulingo wamagetsi olowera, chosinthira cha AC (cholumikizira kapena thyristor) kapena injini yopitilira servo imagwiritsidwa ntchito kusintha kukula kapena polarity yamagetsi owonjezera.Kuti mukwaniritse cholinga chowongolera magetsi, chotsani (kapena kuwonjezera) gawo lapamwamba (kapena gawo losakwanira) lamagetsi olowera.Mphamvu ya thiransifoma yamalipiro ndi pafupifupi 1/7 ya mphamvu yotulutsa, ndipo ili ndi ubwino wa kapangidwe kosavuta komanso mtengo wotsika, koma kukhazikika sikuli kwakukulu.②Kuwongolera manambala a AC voltage stabilizer ndi stepping voltage stabilizer: Dongosolo lowongolera limapangidwa ndi zinthu zomveka kapena ma microprocessors, ndipo matembenuzidwe oyambira a thiransifoma amasinthidwa molingana ndi mphamvu yolowera, kuti voteji yotuluka ikhale yokhazikika.③Purified AC voltage stabilizer: Imagwiritsidwa ntchito chifukwa cha zabwino zake zodzipatula, zomwe zimatha kuthetsa kusokoneza kwakukulu kwa gridi yamagetsi.
