Nws yog ib qho khoom siv hluav taws xob uas kho thiab tswj qhov hluav taws xob AC, thiab nyob rau hauv qhov ntsuas qhov ntsuas hluav taws xob, tuaj yeem tswj cov zis hluav taws xob nyob rau hauv qhov kev teev tseg los ntawm kev tswj hluav taws xob.
Tseem ceeb
Txawm hais tias muaj ntau hom AC voltage regulators, lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub ntsiab Circuit Court yog txawv, tab sis qhov tseem ceeb (tshwj tsis yog rau AC parameter voltage regulators) yog cov tswv yim hloov cov qauv circuits, tswj circuits, voltage.
1. Cov tswv yim hloov pauv: Raws li kev hloov pauv hloov pauv ntawm lub zog hluav taws xob, lub tshuab hluav taws xob hloov hluav taws xob me me nrog kev tiv thaiv tam sim no feem ntau siv.
Lub zog stabilizer thiab cov khoom siv hluav taws xob ua lub luag haujlwm tiv thaiv.
2. Voltage regulating device: Nws yog ib qho khoom siv uas tuaj yeem kho qhov tso zis voltage.Nws tuaj yeem nce lossis txo qhov tso zis hluav taws xob, uas yog qhov tseem ceeb tshaj plaws ntawm qhov voltage stabilizer.
3. Sampling Circuit Court: nws kuaj pom qhov tso zis voltage thiab tam sim no ntawm qhov hluav taws xob stabilizer, thiab xa cov kev hloov pauv ntawm cov zis hluav taws xob mus rau qhov kev tswj xyuas.
4. Cov cuab yeej tsav tsheb: Txij li thaum lub zog tswj hluav taws xob teeb liab ntawm cov tswj Circuit Court tsis muaj zog, nws yog ib qho tsim nyog yuav tsum tau siv lub tshuab tsav tsheb rau lub hwj chim amplification thiab hloov dua siab tshiab.
5. Tsav cov cuab yeej tiv thaiv: ib qho khoom siv uas txuas thiab txiav tawm qhov tso tawm ntawm qhov hluav taws xob stabilizer.Feem ntau, relays lossis contactors lossis fuses feem ntau yog siv.
6. Tswj Circuit Court: Nws soj ntsuam cov qauv kuaj xyuas Circuit Court.Thaum cov zis hluav taws xob siab, nws xa cov teeb liab tswj kom txo qhov hluav taws xob mus rau lub tshuab tsav tsheb, thiab cov cuab yeej tsav tsheb yuav tsav lub voltage regulator kom txo cov zis voltage.Thaum qhov hluav taws xob qis, lub teeb liab tswj kev nce qhov hluav taws xob raug xa mus rau lub cuab yeej tsav tsheb, thiab cov cuab yeej tsav tsheb yuav tsav lub tshuab hluav taws xob tswj hluav taws xob kom nce qhov tso zis hluav taws xob, txhawm rau txhim kho cov zis hluav taws xob kom ua tiav lub hom phiaj ntawm cov zis ruaj khov. .
Thaum nws pom tias qhov tso zis voltage lossis tam sim no nyob sab nraum qhov kev tswj hwm ntawm tus tswj hwm.Lub Circuit Court tswj yuav tswj cov khoom siv tiv thaiv tawm los txiav tawm cov zis los tiv thaiv cov khoom siv hluav taws xob, thaum cov khoom siv tiv thaiv cov zis txuas nrog cov zis hauv ib txwm muaj, thiab cov khoom siv hluav taws xob tuaj yeem tau txais cov khoom siv hluav taws xob ruaj khov.
Kev faib tshuab
Ib qho khoom siv hluav taws xob uas tuaj yeem muab AC lub zog ruaj khov rau lub nra.Kuj tseem hu ua AC voltage stabilizer.Rau qhov tsis zoo thiab qhov ntsuas tau zoo ntawm AC stabilized fais fab mov, thov xa mus rau DC stabilized fais fab mov.Ntau yam khoom siv hluav taws xob xav tau cov khoom siv hluav taws xob AC ruaj khov, tshwj xeeb tshaj yog thaum siv tshuab computer siv rau ntau qhov chaw, cov khoom siv hluav taws xob ncaj qha los ntawm AC daim phiaj hluav taws xob yam tsis muaj kev ntsuas tsis tuaj yeem ua tau raws li qhov xav tau.
AC stabilized fais fab mov muaj ntau hom kev siv thiab ntau hom, uas tuaj yeem faib ua 6 hom hauv qab no.
① Ferromagnetic resonance AC voltage stabilizer: Ib qho AC voltage stabilizer ntaus ntawv ua los ntawm kev sib xyaw ua ke ntawm cov choke choke coil thiab cov capacitor sib xws nrog cov yam ntxwv tsis tu ncua thiab volt-ampere.Hom magnetic saturation yog cov qauv tsim thaum ntxov ntawm hom regulator.Nws muaj cov qauv yooj yim, kev tsim khoom yooj yim, kev hloov pauv dav dav ntawm cov khoom siv hluav taws xob, kev lag luam txhim khu kev qha thiab muaj zog tshaj qhov muaj peev xwm.Tab sis lub waveform distortion yog loj thiab stability tsis siab.Lub tam sim no tsim voltage stabilizer transformer kuj yog ib lub hwj huam mov ntaus ntawv uas paub txog voltage stabilization los ntawm cov nonlinearity ntawm electromagnetic Cheebtsam.Qhov sib txawv ntawm nws thiab cov sib nqus saturation regulator nyob rau hauv qhov sib txawv ntawm cov qauv ntawm lub magnetic Circuit Court, thiab cov hauv paus ntsiab lus ntawm kev ua hauj lwm yog tib yam.Nws paub txog ob txoj haujlwm ntawm kev tswj hluav taws xob thiab kev hloov hluav taws xob nyob rau tib lub sijhawm ntawm ib tus tub ntxhais hlau, yog li nws yog qhov zoo tshaj rau lub zog hluav taws xob zoo tib yam thiab sib nqus saturation voltage regulators.
②Magnetic amplifier hom AC voltage stabilizer: ib lub cuab yeej uas txuas cov magnetic amplifier thiab cov autotransformer hauv series, thiab siv cov hluav taws xob hluav taws xob los hloov cov impedance ntawm magnetic amplifier kom stabilize cov zis voltage.Nws daim ntawv Circuit Court tuaj yeem yog linear amplification lossis pulse width modulation.Hom kev tswj hwm no muaj lub kaw lus kaw nrog kev tawm tswv yim tswj, yog li nws muaj kev ruaj ntseg siab thiab zoo tso zis waveform.Txawm li cas los xij, vim yog siv cov khoom sib nqus amplifiers nrog cov inertia loj dua, lub sijhawm rov qab tau ntev dua.Vim yog txoj kev sib txuas ntawm tus kheej, lub peev xwm tiv thaiv kev cuam tshuam tsis zoo.
③Sliding AC voltage stabilizer: Ib qho cuab yeej uas hloov txoj hauj lwm ntawm zawv zawg sib cuag ntawm lub transformer kom stabilize qhov tso zis voltage, uas yog, tsis siv neeg voltage tswj AC voltage stabilizer tsav los ntawm lub servo lub cev muaj zog.Hom regulator no muaj kev ua haujlwm siab, zoo tso zis voltage waveform, thiab tsis muaj tshwj xeeb yuav tsum tau rau qhov xwm ntawm lub load.Tab sis lub stability yog tsawg thiab lub sij hawm rov qab yog ntev.
④ Inductive AC voltage stabilizer: ib qho cuab yeej uas tswj cov zis AC voltage los ntawm kev hloov cov theem sib txawv ntawm qhov nruab nrab voltage ntawm lub transformer thiab thawj voltage.Nws zoo ib yam nyob rau hauv cov qauv rau ib tug hlau qhov txhab asynchronous lub cev muaj zog, thiab nyob rau hauv lub hauv paus ntsiab lus yog zoo li ib tug induction voltage regulator.Nws qhov kev tswj hwm qhov hluav taws xob yog qhov dav, qhov tso zis voltage waveform yog qhov zoo, thiab lub zog tuaj yeem ncav cuag ntau pua kilowatts.Txawm li cas los xij, vim tias lub rotor feem ntau raug kaw, lub zog siv tau loj thiab qhov ua tau zoo yog tsawg.Tsis tas li ntawd, vim muaj cov khoom siv tooj liab thiab hlau ntau, yuav tsum muaj tsawg dua.
⑤ Thyristor AC voltage stabilizer: AC voltage stabilizer uas siv thyristor ua lub zog hloov pauv.Nws muaj qhov zoo ntawm kev ruaj ntseg siab, ceev teb thiab tsis muaj suab nrov.Txawm li cas los xij, vim muaj kev puas tsuaj rau lub mains waveform, nws yuav ua rau muaj kev cuam tshuam rau cov khoom siv sib txuas lus thiab cov khoom siv hluav taws xob.
⑥Relay AC voltage stabilizer: siv relay ua AC voltage stabilizer los kho qhov winding ntawm lub autotransformer.Nws muaj qhov zoo ntawm cov kev cai dav dav, cov lus teb ceev ceev thiab cov nqi tsim khoom tsawg.Nws yog siv rau txoj kev teeb pom kev zoo thiab siv tej thaj chaw deb hauv tsev.
Nrog rau kev txhim kho cov cuab yeej siv hluav taws xob, cov nram qab no peb hom tshiab ntawm AC stabilized fais fab mov tau tshwm sim hauv xyoo 1980s.①Compensated AC voltage stabilizer: tseem hu ua ib nrab hloov voltage stabilizer.Qhov ntxiv qhov hluav taws xob ntawm qhov them nyiaj hloov pauv yog txuas nrog hauv cov kab nruab nrab ntawm cov khoom siv hluav taws xob thiab cov khoom thauj.Nrog rau theem ntawm cov input voltage, ib qho kev sib tshuam AC hloov (tus neeg sib cuag los yog thyristor) los yog lub servo lub cev muaj zog txuas ntxiv yog siv los hloov qhov loj lossis polarity ntawm qhov ntxiv voltage.Txhawm rau ua tiav lub hom phiaj ntawm kev tswj hluav taws xob, rho tawm (lossis ntxiv) qhov siab dua (lossis ib feem tsis txaus) ntawm cov khoom siv hluav taws xob.Lub peev xwm ntawm kev them nyiaj hloov pauv tsuas yog kwv yees li 1/7 ntawm cov zis hluav taws xob, thiab nws muaj qhov zoo ntawm cov qauv yooj yim thiab tus nqi qis, tab sis kev ruaj ntseg tsis siab.②Numerical control AC voltage stabilizer thiab stepping voltage stabilizer: Kev tswj Circuit Court yog tsim los ntawm cov ntsiab lus logic lossis microprocessors, thiab cov thawj lem ntawm lub transformer yog hloov dua siab tshiab raws li cov input voltage, thiaj li hais tias cov zis voltage yuav stabilized.③ Purified AC voltage stabilizer: Nws yog siv vim nws cov txiaj ntsig zoo ntawm kev sib cais, uas tuaj yeem tshem tawm qhov cuam tshuam siab tshaj plaws los ntawm kab hluav taws xob.
