Kev Taw Qhia Kev Tawm Taw Li High Frequency

Yog hais tias koj xav yuav hauv / efd / efd / etd / erl hom transformers hauv Suav teb, koj yuav tsum paub cov suav transformers manufacturers thiab er hom switching transformer lub thawv exporter. Muaj ntau ntau yam ntawm cov kis high hlau transformer factories hauv Suav teb. Qhov tseem ceeb tshaj plaws yog qhov uas koj yuav tsum paub txog cov pa roj carbon ntau .

  Tsab xov xwm no yuav qhia meej meej txog cov pa roj carbon ntau.

Lub tshuab hluav taws xob feem ntau yog qhov tseem ceeb tshaj ntawm cov khoom siv hluav taws xob. Muaj ntau yam khoom hauv kev hloov khoom siv fais fab. Piv txwv li, ib qho hluav taws xob hloov hluav taws xob ib nrab hnub, uas tau hloov ob lub transistors los ua kom muaj lub siab muaj suab paj nruag ntawm 100 kHz, thiab tom qab ntawd tau hloov los ntawm ib lub tshuab hluav taws xob rau cov zis hloov tam sim no, thiab qhov ratio ntawm cov kev lem ntawm txhua qhov sib ntswg ntawm qhov kev hloov ua muaj suab ntau zaus txiav txim siab qhov tso tawm qhov hluav taws xob. Qhov kev pom zoo tshaj plaws ntawm qhov nruab nrab ib nrab ntawm tus choj transformer circuits yog peb qhov kev hloov ua loj ua ke: lub tshuab hluav taws xob tseem ceeb, tus tsav tsheb thiab lub chaw txua hluav taws xob (qhov chaw nres tsheb tos), txhua tus uas muaj nws cov kev ntsuas hauv lub tebchaws. Siv lub tshuab hluav taws xob ua ib qho piv txwv, ntev li ntev nws yog ib lub hwjchim ntawm 200W lossis ntau tshaj, nws cov kabmob (qhov siab) yuav tsum tsis pub tsawg tshaj 35 hli. Lub cav hloov cav, thaum lub hwj chim ntawm lub hwj chim tsis pub tshaj 300W, tub ntxhais txoj kab nruab nrab ntawm 16 hli yog txaus.

Cov neeg ua haujlwm txig ua haujlwm ua haujlwm siab:

Lub tshuab hluav taws xob yog ib qho cuab yeej ua kom hloov tau qhov hloov voltage, tam sim no, thiab impedance. Thaum ib qho hloov tam sim no dhau los ntawm thawj kauj pliag, ib qho kev sib txuas ntawm magnetic flux yog tsim los ntawm cov tub ntxhais hlau (los yog cov tub ntxhais) los ntxias qhov muaj teeb meem (los yog tam sim no) nyob rau hauv qhov kev sib txuas secondary.

Lub tshuab ua kom muaj ib tus tub ntxhais (los yog cov tub ntxhais) thiab lub coil. Cov kauj muaj ob los sis ntau dua. Qhov sib txuas nrog lub hwj huam khoom yog hu ua thawj kauj, thiab lwm qhov kev sib tw yog hu ua secondary coil.

Kev siv cov neeg hloov tsheb loj:

Qhov kev hloov ua lub siab hloov siab yog lub zog ua hluav taws xob nrog kev ua hauj lwm ntau tshaj qhov nrab zaus (10 kHz). Nws tsuas yog siv rau kev siv hluav taws xob pauv ntau hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab tseem rau cov neeg ua haujlwm high-frequency inverter cov khoom siv hluav taws xob thiab high-frequency inverter welding machines. Kuj tsis paub meej lub zog transformer. Raws li kev ua haujlwm, nws tuaj yeem faib ua ntau qib: 10kHz-50kHz, 50kHz-100kHz, 100kHz ~ 500kHz, 500kHz ~ 1 MHz, 1MHz lossis siab dua. Thaum lub hwj huam kis tau tus mob loj, lub hwj huam fais fab feem ntau txais IGBT. Vim cov IGBT muaj qhov teeb meem tailing tam sim no, qhov kev khiav hauj lwm zaus tsawg kuj; lub hwj huam sib kis tau yog tsawg, thiab MOSFET siv tau, thiab kev khiav hauj lwm zaus yog tus neeg siab zog.
