Sisixhobo sombane esilungelelanisa kwaye silawule amandla ombane e-AC, kwaye ngaphakathi koluhlu lwegalelo lombane oluchaziweyo, sinokuzinzisa umbane ophumayo ngaphakathi koluhlu oluchaziweyo ngolawulo lombane.
Isiseko
Nangona kukho iintlobo ezininzi zolawulo lombane we-AC, umgaqo wokusebenza wesekethe engundoqo wahlukile, kodwa ngokusisiseko (ngaphandle kweparameter voltage regulators AC) ngokwesiseko igalelo lokutshintsha iisampulu zeesekethe, iisekethe zolawulo, amandla ombane.
1. Ukutshintsha igalelo: Njengotshintsho olusebenzayo lwegalelo lwe-voltage stabilizer, uhlobo lokutshintsha umoya oluncinci lwesiphaluka olunokhuseleko oluncinci lusetyenziswa ngokubanzi.
I-voltage stabilizer kunye nezixhobo zombane zidlala indima yokukhusela.
2. Isixhobo sokulawula i-voltage: Sisixhobo esinokuhlengahlengisa i-voltage ephumayo.Inokunyusa okanye inciphise i-voltage ephumayo, eyona nxalenye ibalulekileyo ye-voltage stabilizer.
3. I-sampling circuit: ibona i-voltage ye-output kunye ne-current ye-voltage stabilizer, kwaye idlulisa utshintsho lwe-voltage ephumayo kwisiphaluka sokulawula.
4. Isixhobo sokuqhuba: Ekubeni isignali yombane yokulawula isiphaluka solawulo sibuthathaka, kuyimfuneko ukusebenzisa isixhobo sokuqhuba ukukhulisa amandla kunye nokuguqulwa.
5. Isixhobo sokukhusela idrayivu: isixhobo esidibanisa kwaye sikhuphe ukukhutshwa kwe-voltage stabilizer.Ngokuqhelekileyo, ii-relays okanye abafowunelwa okanye i-fuses zisetyenziswa ngokuqhelekileyo.
6. Ulawulo lwesekethe: Ihlalutya imodeli yokukhangela isampuli yesekethe.Xa i-voltage ephumayo iphezulu, ithumela isignali yokulawula ukunciphisa i-voltage kwisixhobo sokuqhuba, kwaye isixhobo sokuqhuba siya kuqhuba i-voltage regulator ukuthoba i-voltage ephumayo.Xa i-voltage isezantsi, isiginali yokulawula ukonyusa i-voltage ithunyelwa kwisixhobo sokuqhuba, kwaye isixhobo sokuqhuba siya kuqhuba isixhobo sokulawula umbane ukunyusa i-voltage ephumayo, ukuze kuzinziswe umbane wokuphuma ukufezekisa injongo yemveliso ezinzileyo. .
Xa kufunyaniswe ukuba i-voltage ephumayo okanye yangoku ingaphandle koluhlu lolawulo lomlawuli.Isiphaluka solawulo siya kulawula isixhobo sokukhusela isiphumo sokuqhawula umphumo wokukhusela izixhobo zombane, ngelixa isixhobo sokukhusela imveliso sixhunyiwe kwimveliso phantsi kweemeko eziqhelekileyo, kwaye izixhobo zombane zinokufumana ukunikezelwa kombane ozinzile.
Ukuhlelwa koomatshini
Isixhobo sombane esinokunika amandla e-AC azinzileyo kumthwalo.Ikwabizwa ngokuba yi-AC voltage stabilizer.Ngeeparamitha kunye nezalathi zomgangatho we-AC ozinzile unikezelo lwamandla, nceda ubhekisele kwi-DC ezinzile unikezelo lwamandla.Izixhobo zombane ezahlukeneyo zifuna unikezelo lwamandla oluzinzileyo lwe-AC, ngakumbi xa iteknoloji yekhompyutha isetyenziswa kwiinkalo ezahlukeneyo, unikezelo lwamandla oluthe ngqo olusuka kwigridi yamandla e-AC ngaphandle kokuthatha nawaphi na amanyathelo alunakukwazi ukuhlangabezana neemfuno.
Unikezelo lwamandla oluzinzisiweyo lwe-AC lunoluhlu olubanzi losetyenziso kunye neentlobo ezininzi, ezinokuthi zahlulwe ngokungqongqo zibe zezi ntlobo zintandathu zilandelayo.
① I-Ferromagnetic resonance AC voltage stabilizer: Isixhobo sokuzinzisa amandla ombane we-AC esenziwe ngokudityaniswa kwekhoyili egcweleyo yokuqukuqela kunye necapacitor ehambelanayo enevoltheji engaguqukiyo kunye neempawu zevolti-ampere.Uhlobo lokuzalisa imagnethi sisakhiwo esiqhelekileyo solu hlobo lwesilawuli.Inesakhiwo esilula, ukuveliswa okufanelekileyo, uluhlu olubanzi oluvumelekileyo lombane wokufakelwa, ukusebenza okuthembekileyo kunye nomthamo oqinileyo wokulayisha.Kodwa ukugqwethwa kwe-waveform kukhulu kwaye uzinzo aluphezulu.I-voltage stabilizer transformer esandul' ukuphuhliswa ikwasisixhobo sokubonelela ngombane esiqonda ukuzinziswa kwamandla ombane ngendlela yokungahambelani kwezinto ze-electromagnetic.Umahluko phakathi kwayo kunye ne-regulator saturation yamagnetic ilele kumahluko kwisakhiwo sesekethe yamagnetic, kwaye umgaqo osisiseko wokusebenza uyafana.Iqaphela imisebenzi emibini yolawulo lwamandla ombane kunye nokuguqulwa kwamandla ombane ngaxeshanye kumbindi wentsimbi enye, ngoko ke ingaphezulu kuneziguquli zamandla eziqhelekileyo kunye nezilawuli zombane wokuzalisa amandla ombane.
②I-Magnetic amplifier uhlobo lwe-AC voltage stabilizer: isixhobo esidibanisa i-amplifier magnetic kunye ne-autotransformer kuthotho, kwaye isebenzisa isekethe ye-elektroniki ukuguqula i-impedance ye-amplifier yamagnetic ukuzinzisa umbane ophumayo.Ifom yesekethe yayo ingaba yi-linear amplification okanye i-pulse wide modulation.Olu hlobo lomlawuli lunenkqubo evaliweyo kunye nolawulo lwempendulo, ngoko inozinzo oluphezulu kunye ne-wave wave form.Nangona kunjalo, ngenxa yokusetyenziswa kwe-amplifiers magnetic ene-inertia enkulu, ixesha lokubuyisela lide.Ngenxa yendlela yokuzidibanisa, amandla okuchasana nokuphazamiseka akubi.
③I-Sliding AC voltage stabilizer: Isixhobo esitshintsha indawo yoqhagamshelwano olutyibilikayo lwe-transformer ukuzinzisa umbane ophumayo, oko kukuthi, umbane ozenzekelayo olawula ukuzinziswa kombane we-AC oqhutywa yi-servo motor.Olu hlobo lwesilawuli lusebenza kakuhle kakhulu, i-voltage waveform elungileyo, kwaye akukho mfuno zikhethekileyo zohlobo lomthwalo.Kodwa ukuzinza kuphantsi kwaye ixesha lokubuyisela lide.
④ I-inductive AC voltage stabilizer: isixhobo esizinzisa i-voltage ye-AC ephumayo ngokutshintsha umahluko wesigaba phakathi kombane wesibini we-transformer kunye nombane oyintloko.Iyafana nesakhiwo kwinxeba locingo i-asynchronous motor, kwaye ngokomgaqo iyafana ne-induction voltage regulator.Uluhlu lolawulo lwamandla ombane lubanzi, i-voltage waveform ilungile, kwaye amandla anokufikelela kumakhulu eekilowatts.Nangona kunjalo, ngenxa yokuba i-rotor ihlala ivaliwe, ukusetyenziswa kwamandla kukhulu kwaye ukusebenza kakuhle kuphantsi.Ukongezelela, ngenxa yobuninzi bezinto zobhedu kunye nentsimbi, imveliso encinci iyadingeka.
⑤I-Thyristor AC voltage stabilizer: I-AC voltage stabilizer esebenzisa i-thyristor njengento yokulungelelanisa amandla.Ineenzuzo zokuzinza okuphezulu, ukuphendula ngokukhawuleza kwaye akukho ngxolo.Nangona kunjalo, ngenxa yomonakalo kwi-maza waveform, iya kubangela ukuphazamiseka kwizixhobo zonxibelelwano kunye nezixhobo zombane.
⑥I-Relay AC voltage stabilizer: sebenzisa i-relay njenge-AC voltage stabilizer ukulungelelanisa ukujika kwe-autotransformer.Ineenzuzo zoluhlu olubanzi lolawulo lombane, isantya sokuphendula ngokukhawuleza kunye neendleko eziphantsi zokuvelisa.Isetyenziselwa ukukhanyisa ezitalatweni kunye nokusetyenziswa kwekhaya elikude.
Ngokuphuhliswa kobuxhakaxhaka bokubonelela ngombane, ezi ntlobo zintathu zilandelayo zobonelelo lwamandla oluzinzisiweyo lwe-AC lwavela ngeminyaka yoo-1980.①Imbuyekezo ye-AC voltage stabilizer: ekwabizwa ngokuba yi-partial adjustment voltage stabilizer.I-voltage eyongezelelweyo ye-transformer yembuyekezo ixhunyiwe kwichungechunge phakathi kokunikezelwa kwamandla kunye nomthwalo.Ngomgangatho we-voltage yegalelo, i-intermittent AC switch (i-contactor okanye i-thyristor) okanye i-servo motor eqhubekayo isetyenziselwa ukutshintsha ubungakanani okanye i-polarity ye-voltage eyongezelelweyo.Ukufezekisa injongo yokulawulwa kwamandla ombane, thabatha (okanye ungeze) inxalenye ephezulu (okanye inxalenye engonelanga) yegalelo lombane.Umthamo we-transformer yembuyekezo kuphela malunga ne-1/7 yamandla aphumayo, kwaye ineenzuzo zesakhiwo esilula kunye neendleko eziphantsi, kodwa ukuzinza akuphezulu.② Ulawulo lwamanani I-AC voltage stabilizer kunye ne-steping voltage stabilizer: Isiphaluka solawulo senziwe ngezinto ezinengqondo okanye i-microprocessors, kwaye ukujika okuphambili kwe-transformer kuguqulwa ngokuhambelana nombane wokufakelwa, ukuze umbane ophumayo uzinze.③Izinzisi zombane ze-AC ezihlanjululweyo: Isetyenziswa ngenxa yesiphumo sayo esihle sokwahlula, esinokususa uphazamiseko oluphezulu kwigridi yamandla.
