Ukwethulwa kwe-AC voltage stabilizer

Kuwumshini kagesi olungisa futhi ulawule i-voltage ye-AC, futhi ngaphakathi kwebanga lokufakwa kwe-voltage elishiwo, engakwazi ukuzinzisa i-voltage ephumayo phakathi kwebanga elishiwo ngokulawulwa kwamandla kagesi.

Okuyisisekelo

Nakuba kunezinhlobo eziningi zezilawuli zamandla kagesi e-AC, isimiso sokusebenza sesekethe eyinhloko sihlukile, kodwa ngokuyisisekelo (ngaphandle kwezilawuli zamandla kagesi wepharamitha ye-AC) ngokuyisisekelo zingamasekhethi okufaka amasampula okushintsha, amasekhethi okulawula, amandla kagesi.

1. Iswishi yokokufaka: Njengeswishi esebenzayo yokufaka ye-voltage stabilizer, uhlobo lweswishi yomoya i-breaker encane enokuvikelwa kwamanje okulinganiselwe ngokuvamile kusetshenziswa.

I-voltage stabilizer nemishini kagesi idlala indima yokuvikela.

2. Idivayisi elawula amandla kagesi: Iwumshini ongalungisa i-voltage ephumayo.Ingakhuphula noma yehlise i-voltage ephumayo, okuyingxenye ebaluleke kakhulu ye-voltage stabilizer.

3. Isekethe yesampula: ithola i-voltage ephumayo kanye namanje ye-voltage stabilizer, futhi idlulisele ukuguqulwa kwe-voltage okukhiphayo kumjikelezo wokulawula.

4. Idivayisi yokushayela: Njengoba isignali kagesi yokulawula yesifunda sokulawula ibuthakathaka, kuyadingeka ukusebenzisa idivayisi yokushayela ukukhulisa amandla nokuguqulwa.

5. Idivayisi yokuvikela idrayivu: idivayisi exhuma futhi inqamule ukuphuma kwe-voltage stabilizer.Ngokuvamile, ama-relay noma ama-contactor noma ama-fuse avame ukusetshenziswa.

6. Umjikelezo wokulawula: Ihlaziya imodeli yokutholwa kwesifunda esiyisampula.Uma i-voltage ephumayo iphezulu, ithumela isignali yokulawula ukunciphisa i-voltage kudivayisi yokushayela, futhi idivayisi yokushayela izoshayela isilawuli sikagesi ukuze sehlise i-voltage ephumayo.Uma i-voltage iphansi, isignali yokulawula yokwandisa i-voltage ithunyelwa kudivayisi yokushayela, futhi idivayisi yokushayela izoshayela idivayisi elawula amandla kagesi ukuze kwenyuswe i-voltage ephumayo, ukuze kuzinzise amandla kagesi okukhiphayo ukuze kufezwe injongo yokuphuma okuzinzile. .

Uma kutholwa ukuthi i-voltage ephumayo noma yamanje ingaphandle kwebanga lokulawula lesilawuli.Isifunda sokulawula sizolawula idivayisi yokuvikela okukhiphayo ukuze inqamule okukhiphayo ukuze kuvikelwe okokusebenza kukagesi, kuyilapho idivayisi yokuvikela okukhiphayo ixhunywe kokuphumayo ngaphansi kwezimo ezivamile, futhi okokusebenza kukagesi kungathola ukunikezwa kwamandla kagesi okuzinzile.

Ukuhlukaniswa komshini

Idivayisi ye-elekthronikhi enganikeza amandla e-AC azinzile ekulayisheni.Eyaziwa nangokuthi i-AC voltage stabilizer.Ukuze uthole amapharamitha nezinkomba zekhwalithi zikagesi ozinzile we-AC, sicela ubheke ukunikezwa kwamandla okuzinzile kwe-DC.Imishini ehlukahlukene kagesi idinga ugesi we-AC ozinzile, ikakhulukazi uma ubuchwepheshe bekhompyutha busetshenziswa emikhakheni ehlukahlukene, ukunikezwa kwamandla okuqondile avela kugridi yamandla e-AC ngaphandle kokuthatha noma yiziphi izinyathelo ngeke kusahlangabezana nezidingo.

Ukunikezwa kwamandla okuzinzile kwe-AC kunokusetshenziswa okubanzi nezinhlobo eziningi, ezingahlukaniswa cishe zibe izinhlobo eziyisithupha ezilandelayo.

① I-Ferromagnetic resonance AC voltage stabilizer: Idivaysi yokuqinisa amandla kagesi ye-AC eyenziwe ngenhlanganisela yekhoyili egcweleyo yokuklinywa kanye ne-capacitor ehambisanayo enezici ze-voltage ezingashintshi kanye nezici ze-volt-ampere.Uhlobo lwe-magnetic saturation luyisakhiwo esivamile salolu hlobo lwesilawuli.Inesakhiwo esilula, ukwakhiwa okulungile, ububanzi obuvumelekile bobubanzi be-voltage yokufaka, ukusebenza okuthembekile kanye nomthamo oqinile wokugcwala.Kodwa ukuhlanekezela kwe-waveform kukhulu futhi ukuzinza akuphakeme.I-voltage stabilizer transformer esanda kuthuthukiswa futhi iyisisetshenziswa sokuphakela amandla esibona ukuqiniswa kwe-voltage ngokungahambisani kwezingxenye ze-electromagnetic.Umehluko phakathi kwayo nesilawuli sikazibuthe sokugcwaliswa kwesimo usemehlukweni wesakhiwo somjikelezo kazibuthe, futhi isimiso esiyisisekelo sokusebenza siyefana.Iqaphela imisebenzi embaxambili yokulawulwa kwamandla kagesi kanye nokuguqulwa kwamandla kagesi ngesikhathi esifanayo kumongo wensimbi owodwa, ngakho iphakeme kuneziguquli zamandla ezijwayelekile kanye nezilawuli zikagesi zokugcwala kwamandla kazibuthe.

②Isikhulisi sikazibuthe sohlobo lwe-AC voltage stabilizer: idivayisi exhuma isikhulisi kazibuthe kanye ne-autotransformer ochungechungeni, futhi lisebenzisa isekethe ye-elekthronikhi ukuze kuguqulwe ukuthinteka kwesikhulisi sizibuthe ukuze kunzinziswe i-voltage ephumayo.Ifomu layo lesifunda lingaba ukukhuliswa komugqa noma ukuguquguquka kobubanzi be-pulse.Lolu hlobo lwesilawuli lunohlelo lwe-loop oluvaliwe olunokulawula impendulo, ngakho lunokuqina okuphezulu kanye ne-waveform ephumayo enhle.Kodwa-ke, ngenxa yokusetshenziswa kwama-amplifiers kazibuthe ane-inertia enkulu, isikhathi sokutakula side.Ngenxa yendlela yokuzihlanganisa, ikhono lokulwa nokuphazamiseka liphansi.

③Isinzinzisi se-voltage ye-AC esishelelayo: Idivayisi eshintsha indawo yokuthintana okuslayidayo kwe-transformer ukuze izinze ugesi ophumayo, okungukuthi, i-othomathikhi elawula ukuqina kwamandla kagesi we-AC eshayelwa yinjini ye-servo.Lolu hlobo lwesilawuli lusebenza kahle kakhulu, i-waveform ye-voltage ephumayo enhle, futhi azikho izidingo ezikhethekile zemvelo yomthwalo.Kodwa ukuzinza kuphansi futhi isikhathi sokululama side.

④ I-inductive AC voltage stabilizer: idivayisi ezinzisa i-voltage ye-AC ephumayo ngokushintsha umehluko wesigaba phakathi kwe-voltage yesibili ye-transformer kanye ne-voltage eyinhloko.Iyafana ngesakhiwo ne-asynchronous motor yenxeba lenxeba, futhi ngokomthetho ifana nesilawuli se-voltage yokungeniswa.Ibanga layo lokulawula i-voltage libanzi, i-voltage waveform yokuphumayo yinhle, futhi amandla angafinyelela kumakhulu ama-kilowatts.Kodwa-ke, ngenxa yokuthi i-rotor ivame ukukhiyiwa, ukusetshenziswa kwamandla kukhulu futhi ukusebenza kahle kuphansi.Ngaphezu kwalokho, ngenxa yobuningi bezinto zethusi nezensimbi, ukukhiqizwa okuncane kuyadingeka.

⑤I-Thyristor AC voltage stabilizer: I-AC voltage stabilizer esebenzisa i-thyristor njengento yokulungisa amandla.Inezinzuzo zokuzinza okuphezulu, ukusabela okusheshayo futhi akukho msindo.Kodwa-ke, ngenxa yokulimala kwe-waveform yama-mains, kuzodala ukuphazamiseka kwemishini yokuxhumana nemishini kagesi.

⑥Relay AC voltage stabilizer: sebenzisa i-relay njenge-AC voltage stabilizer ukuze ulungise ukujika kwe-autotransformer.Inezinzuzo zebanga elibanzi lokulawulwa kwamandla kagesi, isivinini sokuphendula esisheshayo kanye nezindleko eziphansi zokukhiqiza.Isetshenziselwa ukukhanyisa emgwaqweni nokusetshenziswa kwekhaya kude.

Ngokuthuthukiswa kobuchwepheshe bokuhlinzeka ngogesi, lezi zinhlobo ezintathu ezintsha ezilandelayo zokunikezwa kwamandla okuzinzile kwe-AC zavela ngeminyaka yawo-1980.①Isinzinzisi se-voltage ye-AC esinxeshezelwe: esaziwa nangokuthi isinzinzisi sokulungiswa kwe-voltage ingxenye.I-voltage eyengeziwe ye-transformer yesinxephezelo ixhunywe ochungechungeni phakathi kokunikezwa kwamandla nomthwalo.Ngezinga le-voltage yokufaka, inkinobho ye-AC eshintshashintshayo (othintana naye noma i-thyristor) noma i-servo motor eqhubekayo isetshenziselwa ukushintsha usayizi noma i-polarity ye-voltage eyengeziwe.Ukuze ufeze inhloso yokulawulwa kwamandla kagesi, khipha (noma wengeze) ingxenye ephezulu (noma ingxenye enganele) ye-voltage yokufaka.Umthamo we-transformer yesinxephezelo kuphela mayelana ne-1/7 yamandla okukhipha, futhi unezinzuzo zesakhiwo esilula nezindleko eziphansi, kodwa ukuzinza akuphakeme.② Ukulawulwa kwezinombolo kwe-AC voltage stabilizer kanye ne-steping voltage stabilizer: Isifunda sokulawula sakhiwe ngezinto ezinengqondo noma ama-microprocessors, futhi ukuphenduka okuyinhloko kwe-transformer kuguqulwa ngokuvumelana ne-voltage yokufaka, ukuze i-voltage ephumayo ikwazi ukuzinza.③I-Purified AC voltage stabilizer: Isetshenziswa ngenxa yomphumela wayo omuhle wokuzihlukanisa, ongasusa ukuphazamiseka okukhulu kugridi yamandla.
