Lub cim ntawmFais fais hloov transformeryog (t lossis tm), uas yog cov cuab yeej tseem ceeb tshaj plaws hauv kev hloov. Lub luag haujlwm tseem ceeb ntawm lub zog hloov hluav taws xob yog nce hluav taws xob kom pab txhawb kev xa khoom tsim nyog, faib khoom thiab siv hluav taws xob hluav taws xob. Lub zog hloov hluav taws xob tau muab faib ua cov hloov pauv ntawm cov kauj ruam thiab cov kauj ruam-qis transformers raws li qhov kev hloov pauv hluav taws xob. Chaw hloov chaw ua haujlwm Txhua yam siv cov kauj ruam-qis hloov pauv. Cov kauj ruam kauj ruam-nqes hloov pauv ntawm kev hloov chaw nyob tom plab yog hu ua kev faib khoom xa tuaj. Lub zog hloov hluav taws xob tau muab faib ua R8 muaj peev xwm series thiab R10 muaj peev xwm series raws li muaj peev xwm series. Kuv lub teb chaws hloov tshiab muaj peev xwm ua tau zoo R10 series, thiab muaj peev xwm muaj 100, 120, 3100, 500, 1000kva, thiab lwm yam.
Lub zog hloov hluav taws xob tau muab faib ua ib ntu-theem thiab peb-theem raws li tus naj npawb ntawm theem. Cov chaw hloov chaw ua haujlwm feem ntau siv peb-theem hloov pauv. Cov kev hloov hluav taws xob tau muab faib ua ob pawg raws li cov kev cai voltage (tseem hu ua tsis muaj-excititation voltage txoj cai. Feem ntau cov kev hloov chaw tsim khoom siv tsis-load voltage-tswj kev hloov pauv. Lub zog hloov hluav taws xob tau muab faib ua ob pawg raws li cov khoom siv ntawm cov winding (chev): Tooj winding thiab Aluminium winding. Cov kev hloov chaw ua haujlwm tam sim no feem ntau siv qis-poob hloov pauv hloov pauv. Lub zog hloov hluav taws xob tau muab faib ua ob pawg raws li cov tshuab winding: muab cov tshuab cua tshuab sib dhos, peb-cua tshuab hluav taws xob thiab cov autotransformers. Lub Hoobkas hloov feem ntau siv cov tshuab cua cua cua dub.
Cov kev hloov hluav taws xob tau muab faib ua cov roj-raus, qhuav thiab muaj roj puv (SF6 Ntawm lawv, cov roj tov roj xyaw suav nrog cov roj-txias kom txias, roj-raus dej txias, roj-raus dej-txias thiab yuam cov roj ncig txias. Feem ntau cov kev hloov chaw siv cov roj-imersed tus kheej cua txias hloov pauv. Cov tshuab hluav taws xob sib xyaw ua ke tau muab faib ua ob pawg raws li cov khoom tseem ceeb raws li cov ntawv sinlicon steel steel core transformers thiab amorphous alloy cov hloov pauv. Amorphous alloy cov hloov pauv hloov tau cov hlau qis thiab muaj zog ntau dua. Lub zog hloov hluav taws xob tau muab faib ua ke rau hauv cov hluav taws xob zoo tib yam Tag nrho cov kev hloov pauv tau siv nyob rau hauv cov chaw muaj kuab thiab cov chaw muaj kev nyab xeeb heev, thiab cov hluav taws xob tiv thaiv kev hloov pauv tau siv hauv cov chaw nrog cov xob laim.
Cov qauv yooj yim ntawm lub zog hloov hluav taws xob suav nrog ob qhov chaw loj: cov tub ntxhais thiab cua. Cov winding tau muab faib ua cov hluav taws xob siab thiab cov hluav taws xob qis lossis theem pib thiab theem nrab. Cov sawv cev thiab lub ntsiab lus ntawm tag nrho cov qauv ntawm lub zog hloov hluav taws xob yog raws li hauv qab no
Cov pawg sib txuas ntawm lub zog hloov pauv yog hais txog qhov sib txawv ntawm cov kab sib txawv ntawm cov kab sib txawv ntawm tus thawj thiab theem nrab, thiab qib theem nrab, thiab tertiary) windings ntawm lub transformer. Muaj ob feem kev sib txuas pab pawg rau {{{{{}}} kv} v): yyn0 (piv txwv li Dyn11 (piv txwv li Δ / y0 -11). Rau dyn 11-} Cov ntawv sib txuas lus sib txuas, yog ib qho kev sib txuas zoo) Harmonic tam sim no kev sib txuas, yog li nws yuav tsis raug txhaj rau cov pej xeem siab-voltage daim phiaj. Qhov no yog ntau dua rau kev thuam tus neeg ua kom muaj kev sib raug zoo hauv lub hwj huam hloov pauv ntau dua li lub hwj huam ua ke nrog kev sib txuas ntawm lub hnub qub. Lub Voj-Sequence Irnedance ntawm lub dyn {15}} me dua li ntawm cov khoom siv tsawg-{16}} Cov av tsis sib xws thiab cov kev tshem tawm ntawm qhov txhaum. Thaum lub qis-voltage sab txuas nrog ib-theem tsis muaj zog thauj khoom, nws muaj peev xwm txo nws lub peev xwm los txuas cov cuab yeej siv hluav taws xob tsawg.
GB {50052-2009 "Tsim Specifications rau Cov Khoom Siv Hluav Taws Xob, Dynkulates: Hauv Kev Hloov Pauv Tsis Tau Xaiv.
Qhov nruab nrab ntawm kab tam sim no ntawm qhov qis-voltage sab ntawm Dyn11 txuas transformer tau tso cai rau ntau dua 75% ntawm cov rated tam sim no ntawm cov yyn {{5} Txuas transformer. Lub rwb thaiv tsev muaj zog yuav tsum tau ntawm lub tshav ntuj winding Yog li ntawd, hauv TN thiab TT systems, thaum qhov qes-voltage tsis tshaj li 25% ntawm ib theem tsis tshaj li cov neeg muaj nqi thaum ub tau txuas ntxiv tseem tuaj yeem xaiv tau.
Xob Laim Tiv Thaiv Kev Hloov Pooj Feem ntau siv Yzn11 kev sib txuas pawg. Cov qauv kev coj ua tau yog qhov kev txhaj tshuaj thib ob yog muab faib ua ob ib ib nrab windings nrog cov tig sib npaug, thiab tus zigzag (z-puab) kev sib txuas yog saws. Thaum cov xob laim ua ntau qhov kev nkag tau raws cov sab thib ob ntawm ob qho kev hloov pauv ntawm ob sab ntawm lub zog sib txawv Ib yam li ntawd, yog tias xob laim hluav taws xob cuam tshuam nrog rau sab nraud ntawm ob sab ntawm sab nraud ntawm sab nraud (qis voltage) ntawm lub transformer sib cais.
