Icho chishandiso chemagetsi chinogadzirisa uye kudzora iyo AC voltage, uye mukati meyakatarwa voltage yekuisa renji, inogona kudzikamisa inobuda voltage mukati meiyo yakatarwa kuburikidza nemagetsi regulation.
Fundamental
Kunyangwe paine akawanda marudzi e AC voltage regulators, musimboti wekushanda wedunhu guru wakasiyana, asi zvakanyanya (kunze kwe AC parameter voltage regulators) zvinonyanya kupinza switch sampling maseketi, kudzora maseketi, voltage.
1. Input switch: Sekupinza kushanda switch yevoltage stabilizer, iyo mhepo switch yemhando diki redunhu breaker ine shoma yekudzivirira ikozvino inowanzoshandiswa.
Iyo voltage stabilizer uye midziyo yemagetsi inoita basa rekudzivirira.
2. Voltage regulating device: Icho chinhu chinogona kugadzirisa kubuda kwemagetsi.Inogona kuwedzera kana kuderedza voltage inobuda, inova chikamu chakakosha cheiyo voltage stabilizer.
3. Sampling circuit: inoona kubuda kwemhepo uye ikozvino yemagetsi ekugadzirisa, uye inotumira shanduko yemagetsi ekubuda kune dunhu rekutonga.
4. Kutyaira mudziyo: Sezvo chiratidzo chemagetsi chekudzora chedunhu chisina simba, zvinodikanwa kushandisa mudziyo wekutyaira kuti uwedzere simba uye kutendeuka.
5. Dhivha yekudzivirira mudziyo: mudziyo unobatanidza uye unobvisa kubuda kweiyo voltage stabilizer.Kazhinji, relay kana macontactor kana fuse anowanzoshandiswa.
6. Kudzora dunhu: Inoongorora sampuli yedunhu rekuona muenzaniso.Kana iyo voltage inobuda yakakwira, inotumira chiratidzo chekudzora kudzikisa voltage kumudziyo wekutyaira, uye mudziyo wekutyaira unotyaira voltage regulator kudzikisa inobuda voltage.Kana voltage yadzikira, chiratidzo chekutonga chekuwedzera voltage chinotumirwa kuchishandiso chekutyaira, uye mudziyo wekutyaira unotyaira mudziyo wekudzora magetsi kuti uwedzere simba rekubuda, kuitira kudzikamisa magetsi anobuda kuti azadzise chinangwa chekubuda kwakagadzikana. .
Kana ichinge yaonekwa kuti yakabuda voltage kana yazvino iri kunze kweiyo control range ye regulator.Saiti yekudzora inodzora mudziyo wekudzivirira unobuda kuti ubvise chinobuda kuchengetedza mudziyo wemagetsi, nepo mudziyo wekudzivirira unobuda wakabatana nekubuda pasi pemamiriro akajairwa, uye midziyo yemagetsi inogona kuwana yakagadzikana magetsi.
Machine classification
Chigadzirwa chemagetsi chinogona kupa simba rakagadzikana re AC kumutoro.Iyo inozivikanwawo se AC voltage stabilizer.Kune ma paramita uye mhando zviratidzo zve AC yakagadzikana magetsi, ndapota tarisa kune iyo DC yakagadzikana magetsi ekupa.Midziyo yemagetsi yakasiyana-siyana inoda yakagadzikana magetsi eAC, kunyanya kana tekinoroji yekombuta ikaiswa kune dzakasiyana siyana, iyo yakananga magetsi kubva kune AC magetsi grid pasina kutora chero matanho haichakwanise kuzadzisa zvinodiwa.
Iyo AC yakagadzikana magetsi ine huwandu hwakasiyana hwekushandisa uye akawanda marudzi, ayo anogona kuganhurwa zvakaganhurwa kuva anotevera marudzi matanhatu.
① Ferromagnetic resonance AC voltage stabilizer: Chishandiso che AC voltage stabilizer chakagadzirwa nemusanganiswa weiyo saturated choke coil uye inoenderana capacitor ine inogara voltage uye volt-ampere maitiro.Iyo magineti saturation mhando ndiyo yekutanga yakajairika chimiro cherudzi urwu rweregulator.Iine chimiro chakareruka, kugadzirwa kuri nyore, kusiyanisa kwakasiyana kwakasiyana-siyana kwemagetsi ekuisa, kushanda kwakavimbika uye simba rakawandisa.Asi iyo waveform kukanganisa kwakakura uye kugadzikana hakuna kukwirira.Iyo ichangoburwa voltage stabilizer transformer zvakare chishandiso chemagetsi chinoona kudzikamisa kwemagetsi nenzira yekusaita kweiyo electromagnetic zvikamu.Musiyano uripo pakati payo neiyo magineti saturation regulator iri mukusiyana kwechimiro cheiyo magineti wedunhu, uye yekutanga kushanda musimboti yakafanana.Inoona mabasa maviri emagetsi ekugadzirisa magetsi uye shanduko yemagetsi panguva imwe chete pane imwe musimboti wesimbi, saka yakakwirira kune akajairwa magetsi emagetsi uye magineti saturation voltage regulators.
②Magineti amplifier mhando AC voltage stabilizer: mudziyo unobatanidza iyo magineti amplifier uye autotransformer munhevedzano, uye inoshandisa yemagetsi dunhu kushandura iyo impedance yemagineti amplifier kudzikamisa yakabuda voltage.Yayo yedunhu fomu inogona kuita mutsara amplification kana pulse wide modulation.Iyi mhando ye regulator ine yakavharwa-loop system ine mhinduro yekudzora, saka ine yakanyanya kugadzikana uye yakanaka kubuda waveform.Zvisinei, nekuda kwekushandiswa kwemagineti amplifiers ane inertia yakakura, nguva yekudzorera yakareba.Nekuda kweiyo yekuzvibatanidza nzira, iyo anti-kupindira kugona kwakashata.
③Sliding AC voltage stabilizer: Chishandiso chinoshandura chinzvimbo chekutsvedza kubatwa kwetransformer kuti igadzikane inobuda voltage, kureva, otomatiki voltage inodzora AC voltage stabilizer inofambiswa ne servo mota.Iyi mhando ye regulator ine hunyanzvi hwepamusoro, yakanaka kubuda voltage waveform, uye hapana zvakakosha zvinodiwa pamhando yemutoro.Asi kugadzikana kwakaderera uye nguva yekudzorera yakareba.
④ Inductive AC voltage stabilizer: mudziyo unodzikamisa inobuda AC voltage nekushandura mutsauko wechikamu pakati pechipiri voltage yetransformer uye yekutanga voltage.Izvo zvakafanana muchimiro kune waya ronda asynchronous mota, uye musimboti yakafanana neye induction voltage regulator.Yayo voltage regulation regulation yakakura, yakabuda voltage waveform yakanaka, uye simba rinogona kusvika mazana emakilowatts.Zvisinei, nokuti rotor inowanzovharwa, kushandiswa kwesimba kwakakura uye kushanda kwakaderera.Mukuwedzera, nekuda kwehuwandu hwemhangura nesimbi zvinhu, kugadzirwa kuduku kunodiwa.
⑤Thyristor AC voltage stabilizer: An AC voltage stabilizer inoshandisa thyristor sechinhu chekugadzirisa simba.Iine zvakanakira kugadzikana kwepamusoro, kupindura nekukurumidza uye pasina ruzha.Nekudaro, nekuda kwekukuvara kweiyo mains waveform, zvinokonzeresa kukanganisa kumidziyo yekutaurirana uye michina yemagetsi.
⑥Relay AC voltage stabilizer: shandisa relay se AC voltage stabilizer kugadzirisa mhepo ye autotransformer.Iyo ine mabhenefiti ehupamhi voltage regulation renji, kukurumidza kupindura kumhanya uye yakaderera mutengo wekugadzira.Inoshandiswa kuvheneka mumugwagwa uye kushandiswa kwemusha kure.
Nekuvandudzwa kwehunyanzvi hwekugovera magetsi, mhando nhatu dzinotevera dze AC dzakadzikama magetsi dzakaonekwa muma1980.① Yakabhadharwa AC voltage stabilizer: inozivikanwawo sechikamu chekugadzirisa voltage stabilizer.Iyo yakawedzera voltage yemubhadharo wekushandura inobatanidzwa mumutsara pakati pemagetsi uye mutoro.Nechiyero cheiyo voltage yekupinda, inopindirana AC switch (contactor kana thyristor) kana inoenderera servo mota inoshandiswa kushandura saizi kana polarity yekuwedzera voltage.Kuti uwane chinangwa chekugadzirisa magetsi, bvisa (kana kuwedzera) chikamu chepamusoro (kana chikamu chisina kukwana) chemagetsi ekuisa.Kugona kwemuripo wekushandura inongosvika 1/7 yesimba rekubuda, uye ine zvakanakira chimiro chakareruka uye yakaderera mutengo, asi kugadzikana hakuna kukwirira.②Nhamba yekudzora AC voltage stabilizer uye inotsika voltage stabilizer: Iyo yekudzora yedunhu inoumbwa nezvinhu zvine logic kana microprocessors, uye matendeuko ekutanga etransformer anoshandurwa zvinoenderana nemagetsi ekuisa, kuitira kuti inobuda voltage igadzikane.③Yakacheneswa AC voltage stabilizer: Inoshandiswa nekuda kwekunaka kwayo yekuzviparadzanisa nevamwe, iyo inogona kubvisa kukanganiswa kwepamusoro kubva kune gidhi remagetsi.
