Muaj nuj nqi ntawm kev hloov hom fais fab mov transformer
Lub luag haujlwm ntawm kev hloov hom fais fab mov transformers
Lub zog hloov hluav taws xob hloov pauv thiab hloov pauv transistor ua ke tsim tus kheej zoo siab (lossis nyias 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 ib lub voj voog flyback, thaum lub tshuab hloov pauv, lub tshuab hloov pauv hloov hluav taws xob mus rau hauv lub zog sib nqus lub zog rau kev cia, thiab thaum lub tshuab hloov pauv, 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 txuas ntxiv mus rau lub nra los ntawm lub zog cia inductor
Hloov cov input DC voltage mus rau hauv ntau yam tsawg voltages xav tau
Classification ntawm Switching Fais Fab Transformers
Switching fais fab mov transformers muab faib ua ib qho excitation switching fais fab mov transformers thiab ob excitation switching fais fab mov transformers. Lub hauv paus ntsiab lus 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 mov transformer yog ib qho polarity mem tes, thiab nws kuj muaj rau pem hauv ntej thiab thim rov qab voltage outputs; Lub input voltage ntawm dual excitation switching fais fab mov transformer yog ib tug bipolar mem tes, feem ntau outputting ib tug bipolar mem tes voltage.
Cov yam ntxwv tsis zoo ntawm hloov hom fais fab mov transformers
Voltage ratio: yog hais txog qhov piv ntawm thawj qhov hluav taws xob mus rau theem nrab voltage ntawm lub transformer
DC kuj: tseem hu ua tooj liab kuj
Efficiency: tso zis hwj chim / input zog * 100 [%]
Rwb thaiv tsev tsis kam: Lub peev xwm rwb thaiv tsev ntawm cov windings ntawm transformer thiab nruab nrab ntawm cov tub ntxhais hlau
Lub zog dielectric: Qhov degree uas lub tshuab hloov hluav taws xob tuaj yeem tiv taus qhov ntsuas hluav taws xob hauv 1 thib ob lossis 1 feeb
Kev sib xyaw ntawm Kev Siv Hluav Taws Xob Transformers
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 ferrite mos, uas tuaj yeem muab faib ua ob pawg raws li lawv qhov muaj pes tsawg leeg thiab kev siv zaus: MnZn series thiab NiZn series. Cov qub muaj siab permeability thiab siab saturation magnetic induction, thiab muaj tsawg poob nyob rau hauv nruab nrab thiab tsawg zaus ranges. 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). Lub rwb thaiv tsev txheej ntawm yav dhau los yog polyester xim, uas muaj superior tshav kub tsis kam, thiab rwb thaiv tsev lub zog muaj peev xwm ncav cuag 60kv / mm; Cov txheej rwb thaiv tsev tom kawg yog ua los ntawm cov xim polyurethane, uas muaj zog ntawm tus kheej-adhesiveness thiab nws tus kheej soldering kev ua tau zoo (380 degree), thiab tuaj yeem welded ncaj qha yam tsis tau tshem cov xim zaj duab xis.
Daim kab xev rhiab heev: Rwb thaiv tsev daim kab xev muaj lub zog hluav taws xob siab, siv tau yooj yim, thiab muaj cov khoom siv zoo. Nws yog dav siv nyob rau hauv interlayer, inter pab pawg neeg rwb thaiv tsev, thiab txheej rwb thaiv tsev ntawm hloov transformer coils. Nws yuav tsum ua tau raws li cov cai hauv qab no: zoo adhesion, tiv thaiv stripping, qee lub zog tensile, zoo rwb thaiv tsev kev ua tau zoo, zoo siab tsis kam, nplaim retardancy, thiab kub tsis kam.
Cov khoom siv pob txha: Cov pob txha ntawm qhov hloov pauv hloov pauv txawv ntawm cov pob txha hloov pauv. Ntxiv nrog rau kev ua haujlwm rwb thaiv tsev thiab cov khoom txhawb nqa rau lub kauj, nws tseem ua lub luag haujlwm hauv 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 hluav taws thiab muaj kev ua haujlwm zoo, ua kom yooj yim rau kev ua ntau yam duab
