Classification ntawm Switching Fais Fab Transformers
Lub tshuab hluav taws xob hloov hluav taws xob yog lub zog hloov hluav taws xob uas sib txuas nrog lub tshuab hluav taws xob hloov hluav taws xob. Nyob rau hauv lub voj voog, ntxiv rau qhov kev hloov pauv ntawm qhov kev hloov pauv ntawm qhov hloov pauv tsis tu ncua, qhov hloov hluav taws xob hloov pauv kuj tseem muaj kev sib cais ntawm rwb thaiv tsev thiab lub zog xa hluav taws xob. Kev hloov hluav taws xob hloov pauv feem ntau yog siv rau hauv cov xwm txheej uas cuam tshuam nrog cov hluav taws xob ntau zaus xws li hloov cov khoom siv hluav taws xob.
Lub luag haujlwm ntawm Kev Hloov Hluav Taws Xob Transformer
Lub zog hloov hluav taws xob hloov pauv thiab hloov raj ua ke ua rau nws tus kheej zoo siab (lossis nws tus kheej zoo siab) sib cuam tshuam oscillator, yog li hloov pauv cov tswv yim DC voltage rau hauv qhov siab-frequency mem tes voltage
Nws ua lub luag haujlwm hauv kev hloov hluav taws xob thiab hloov pauv. Nyob rau hauv lub flyback Circuit Court, thaum lub hloov mus rau hauv, lub transformer converts hluav taws xob lub zog rau hauv magnetic teb zog rau cia. Thaum lub tshuab hluav taws xob kaw, nws raug tso tawm. Nyob rau hauv ib lub voj voog rau pem hauv ntej, thaum hloov pauv, qhov hluav taws xob input yog ncaj qha mus rau lub load thiab lub zog yog khaws cia rau hauv lub zog cia inductor. Thaum lub tshuab hluav taws xob raug kaw, lub zog cia inductor txuas ntxiv mus rau lub nra
Hloov cov input DC voltage mus rau hauv ntau yam tsawg voltages xav tau
Classification ntawm Switching Fais Fab Transformers
Kev hloov hluav taws xob hloov hluav taws xob tau muab faib ua ib qho kev hloov pauv hluav taws xob hloov hluav taws xob thiab ob chav excitation hloov hluav taws xob hloov pauv, thiab cov qauv kev ua haujlwm thiab cov qauv ntawm ob hom kev hloov hluav taws xob hloov pauv tsis zoo ib yam. Lub input voltage ntawm ib qho excitation switching fais fab transformer yog unipolar mem tes, thiab nws kuj outputs rau pem hauv ntej thiab rov qab voltage; Lub input voltage ntawm dual excitation switching fais fab mov transformer yog ib tug bipolar mem tes, uas feem ntau yog ib tug bipolar mem tes voltage tso zis.
Kev sib xyaw ntawm Switching Fais Fab Transformer
Cov ntaub ntawv tseem ceeb ntawm kev hloov hluav taws xob hloov hluav taws xob yog cov khoom sib nqus, cov ntaub ntawv hlau, thiab cov ntaub ntawv rwb thaiv tsev, uas yog cov tub ntxhais ntawm kev hloov pauv hloov pauv.
Cov ntaub ntawv sib nqus: Cov khoom siv sib nqus siv hauv kev hloov pauv hloov pauv yog cov khoom sib nqus ferrite, uas tuaj yeem muab faib ua MnZn series thiab NiZn series raws li lawv muaj pes tsawg leeg thiab daim ntawv thov zaus. Cov qub muaj siab permeability thiab siab saturation magnetic induction, thiab muaj tsawg poob nyob rau hauv nruab nrab thiab tsawg zaus ntau yam. Cov tub ntxhais hlau nplaum muaj ntau yam duab, xws li EI hom, E hom, EC hom, thiab lwm yam
Hlau Khoom - Enamelled Hlau: Feem ntau siv rau winding me me hluav taws xob transformers, muaj ob hom enameled hlau: high-strength polyester enameled hlau (QZ) thiab polyurethane enameled hlau (QA). Raws li lub thickness ntawm cov xim txheej, lawv muab faib ua hom 1 (thin xim hom) thiab hom 2 (thick xim hom). Cov txheej txheej rwb thaiv tsev ntawm yav dhau los yog cov xim polyester, uas muaj cov cua sov zoo heev, thiab cov rwb thaiv tsev thiab hluav taws xob muaj zog tuaj yeem ncav cuag 60kv / mm; Cov txheej rwb thaiv tsev tom kawg yog cov xim polyurethane, uas muaj zog ntawm nws tus kheej-nplaum thiab kev ua haujlwm ntawm tus kheej (380 degree), thiab tuaj yeem ncaj qha welded yam tsis tau tshem cov xim zaj duab xis.
Siab rhiab daim kab xev: Insulating daim kab xev muaj hluav taws xob muaj zog, yog ib qho yooj yim mus use, thiab muaj zoo mechanical zog. Nws yog dav siv nyob rau hauv interlayer, inter pab pawg neeg, thiab sab nraud rwb thaiv tsev ntawm hloov transformer coils. Nws yuav tsum ua kom tau raws li cov hauv qab no: zoo adhesion, tiv thaiv stripping, muaj ib tug tej yam tensile zog, zoo rwb thaiv tsev kev ua tau zoo, zoo voltage kuj, nplaim retardancy, thiab kub kuj.
Cov khoom siv pob txha: Cov pob txha hloov pauv hloov pob txha txawv ntawm cov pob txha hloov pauv dav dav. Ntxiv nrog rau kev ua cov rwb thaiv tsev thiab cov khoom txhawb nqa rau lub kauj, nws kuj tseem ua haujlwm raws li kev teeb tsa, kho, thiab qhov chaw ntawm tag nrho cov transformer. Yog li ntawd, cov khoom siv los ua cov pob txha pob txha yuav tsum tsis tsuas yog ua tau raws li cov txheej txheem rwb thaiv tsev, tab sis kuj muaj lub zog tensile ntau. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv cov vuam kub ntawm cov pins, cov thermal deformation kub ntawm cov khoom siv pob txha yuav tsum siab tshaj 200 degree. Cov khoom siv yuav tsum yog nplaim retardant thiab muaj kev ua tau zoo, Yooj yim rau tshuab rau ntau yam duab
