Dedicated AC voltage regulator
1, tiv thaiv kev cuam tshuam AC tsis tswj fais fab mov
AC parametric tswj fais fab mov, tseem hu ua tsis tu ncua voltage transformer (Constant Voltage Transformer) abbreviated CVT, lub hauv paus ntsiab lus yog siv ferromagnetic resonance hauv paus ntsiab lus ua los ntawm functional converters, ib tug tshwj xeeb qauv ntawm cov hlau core muab tso rau hauv ib tug linear inductance, saturation inductance. thiab them nyiaj ntawm inductance coil, kom ua tiav lawv cov haujlwm. Lub hauv paus tseem ceeb yuav siv cov kab tawm ntawm cov tub ntxhais hlau nplaum sib nqus, thaum cov tub ntxhais kawm theem nrab raug xaiv kom muaj thaj tsam qis qis ntawm cov yam ntxwv sib nqus. Thaum cov input voltage nce ntxiv, nws magnetic teb tsis cuam tshuam rau lub saturated hlau core, thiaj li ua kom tiav lub hom phiaj ntawm kev tswj voltage. Cov qauv ntawm cov khoom siv fais fab no yog qhov tshwj xeeb thiab yooj yim, ruaj khov thiab txhim khu kev qha, kev tswj hluav taws xob ntau yog dav. Thaum cov input voltage txawv ± 20%, cov zis voltage txawv ± 3%, overload tiv thaiv muaj peev xwm; Thaum lub load luv luv Circuit Court, cov zis voltage cia li poob los xyuas kom meej qhov kev ruaj ntseg ntawm cov khoom, lub input thiab output kev ruaj ntseg kev sib cais, tsis muaj hluav taws xob kev twb kev txuas, shielding thiab nqus muaj nuj nqi, ntau pua ntawm hertz mus rau kaum tawm txhiab tus hertz impulse cuam tshuam. Cov teeb liab muaj qhov zoo ntawm ob-txoj kev tsub zuj zuj thiab txo qis, hom kev tsuj ntau dua lossis sib npaug li 50dB. Tsis tas li ntawd, ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws yog txhawm rau tiv thaiv kab sib chaws sib haum xeeb yog pom tseeb, qhov hluav taws xob waveform mus rau qhov kev txhim kho tseem ceeb, qhov thib peb kev sib haum xeeb txo tus nqi ntawm 90% lossis ntau dua, ntawm 5, 6, 7, 8, 11 thiab lwm yam. khib thiab txawm harmonics muaj cuab kev txhim kho, tshwj xeeb tshaj yog rau harmonic pa phem nyob rau hauv txoj kab ntawm ntau yam instrumentation nyob rau hauv lub loj fais fab mov, kuj yuav siv tau rau precision khoom nyob rau hauv lub tswj system hwj chim transformer.
Technology thiab txheej txheem theem, lub tshuab suab nrov yog txo qis, CVT suab nrov thiab cuam tshuam rau kev siv tam sim no tuaj yeem siv nrog kev ntseeg siab.
2, ruaj khov thiab sib haum xeeb tiv thaiv ntawm AC fais fab mov tshiab
Tam sim no, daim phiaj kev sib haum xeeb tau dhau los ua txoj haujlwm tseem ceeb ntawm cov khoom siv hluav taws xob. Nyob rau hauv xyoo tas los no, txoj kev loj hlob ntawm lub hwj chim electronics technology, active zog filtering yog los ua ib tug kev daws teeb meem rau lub hwj chim daim phiaj voltage distortion ntawm lub feem ntau cog lus filtering txoj kev. Kev siv series-type active power filtering method, tau tsim ib hom tshiab ntawm lub hwj huam mov los tswj thiab inhibit harmonics, hu ua series hwj chim zoo xws li (SPQC: Serial Power Quality Controller), zoo ib yam li txawv teb chaws hu ua voltage dynamic restorer. Cov khoom lag luam tuaj yeem tswj hwm qhov hluav taws xob thiab txo cov kab sib txuas sib txuas, tseem hu ua hluav taws xob tswj cov lim dej. Qhov no voltage regulator tseem tuaj yeem yog peb-theem tsis sib npaug voltage flicker, dips, surges, spikes thiab lwm yam kev them nyiaj dynamic, hluav taws xob hluav taws xob tsis ruaj khov, thiab nrog kev sib raug zoo, cov cuab yeej ntsuas tam sim no dynamic voltage them, lub load ntawm lub ntshiab peb-theem sinusoidal balanced. hluav taws xob.
3, Kev kho mob tshwj xeeb fais fab mov
Kev kho mob CT tshuab tau siv dav hauv cov tsev kho mob, yog tias cov khoom siv hluav taws xob tsis raug teeb tsa kom zoo, ua rau muaj kev daws teeb meem tsis zoo ntawm CT zaj duab xis, uas ua rau muaj teeb meem rau tus kws kho mob qhov kev kuaj mob, tab sis kuj tseem muaj peev xwm siv tsis raug ntawm tus mob. CT tshuab nws tus kheej siv cov yam ntxwv ntawm cov khoom siv fais fab: Ua ntej, qhov tawg tawg thaum cov kev cai ntawm kev tswj fais fab tso zis tam sim no loj, qhov hluav taws xob poob me me, qhov tam sim no tsis tswj; Qhov thib ob, CT nws tus kheej muaj lub voj voog rectifier, tsim kom muaj kev sib haum xeeb, qhov cuam tshuam ntawm kev tswj fais fab kev tswj xyuas tsis raug, ntau tshaj kaum xyoo rau GE-CT txhawb kev tsim hluav taws xob, tswj fais fab mov kom txo tau qhov kev tiv thaiv sab hauv, cov zis tawm. txhawm rau ua kom muaj kev sib haum xeeb lim dej thiab tswj cov circuits txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kom muaj kev sib haum xeeb thiab kev tswj xyuas Circuit
4, AC tswj voltage fais fab mov
Nyob rau hauv xyoo tas los no, kev lag luam xav tau yog maj mam loj hlob, feem ntau ntawm cov kev xav tau ntawm lub peev xwm yog qhov loj, cov txheej txheem ntawm cov regulator thiab voltage regulator ua haujlwm raws li cov khoom lag luam rau "regulator voltage regulator power supply" lossis adjustable regulator yuav ruaj khov. Cov khoom muaj induction, lub hwj chim hluav taws xob thiab transformers thiab lwm yam regulators thiab voltage regulators, txhua hom muaj nws tus yam ntxwv thiab shortcomings, tsis tau piav nyob rau hauv no tsab xov xwm. Kev siv ntau theem voltage regulator thiab kem-hom them AC voltage regulator muaj li ntawm kaw-voj kem voltage regulator, regulator thiab ua kom cov zis voltage nyob rau tib lub sij hawm. Cov regulator regulator no tau tsim sai heev nyob rau hauv xyoo tas los no, lub peev xwm ntau ntawm ntau tshaj 30kVA ~ 20 0kVA, nws yog piv nrog induction hom tsis khaws lub taag tig thiab huab cua sib txawv, tsis muaj load tam sim no thiab tsis muaj load. poob yog me me, lub waveform tsis distorted (waveform distortion<0.5%), regulator speed, instantaneous overload capacity, has been widely used.
Lub peev xwm thauj khoom txuas ntxiv txhim kho, kev kub siab thiab lub peev xwm loj ntawm ntau hom hluav taws xob tswj hluav taws xob xav tau kev xav tau tau muab tso rau tom ntej los ntawm lub sijhawm, qee cov neeg siv tau muab tso rau pem hauv ntej regulator 1000kVA ~ 3000kVA kev thov, kev sib raug zoo thiab cov neeg siv khoom xav tau yog lub zog tsav ntawm technologies txoj kev loj hlob, chav tsev ntau lawm rau cov neeg siv, kev tsim kho ntawm ntau lub luag haujlwm, muaj peev xwm loj regulator kom tau raws li cov kev xav tau ntawm lub zej zog regulator AC fais fab mov yog lub luag hauj lwm unshirkable.
