Switching fais fab tuag transformer

Switching fais fab tuag transformer

Switching fais fab tuag yog lub zog ua hluav taws xob nrog switching transistor. Ntxiv rau qhov kev hloov ua hluav taws xob hloov ntawm cov cuab yeej hluav taws xob, nws tseem muaj kev ua haujlwm ntawm kev siv hluav taws xob thiab kev siv hluav taws xob, uas feem ntau siv los hloov kev siv hluav taws xob thiab lwm zaus uas muaj kev tawm suab ntau.

Cov khoom siv tseem ceeb ntawm kev siv cov khoom siv hluav taws xob: cov khoom siv hlau nplaum, cov khoom siv hlau thiab cov khoom siv rwb thaiv tsev yog qhov tseem ceeb ntawm kev siv fais fab tuag.

Sib Nqus Khoom: Cov khoom siv sib nqus uas siv hauv kev hloov hluav taws xob yog muag muag ferrite, uas tau muab faib ua MnZn series thiab NiZn series raws li nws cov lus muaj pes tsawg thiab daim ntawv thov heev.

Cov Khoom Hlau: Cov Hluav Taws Xob (Enameled Wire) rau cov cua tshuab hluav taws xob feem ntau muaj ob hom hluav taws xob muaj zog hluav taws xob (QZ) thiab polyurethane enameled (QA). Raws li lub thickness ntawm enameled txheej, nws muab faib ua 1 hom (thin enameled hlau) thiab 2 hom (tuab enameled xaim). Insulating txheej yog polyurethane xim, nrog muaj zog rau nws tus kheej, nws tus kheej-vuam kev kawm (380 C), yuav tsum ncaj qha welded yam tsis tshem qhov xim zaj dab neeg

Cov kab xev nplaum: cov kab xev thev muaj kev tiv thaiv hluav taws xob, kev siv yooj yim thiab kev kho khoom zoo. Nws yog dav siv nyob rau hauv interlayer, pab pawg neeg dim pa thiab outsourcing rwb thaiv tsev ntawm kev hloov cav ntoo. Nws yuav tsum ua raws li cov hauv qab no: zoo viscosity, ua kom tawv nqaij, qaug zog, qhov hluav taws xob zoo, zoo hluav taws xob, hluav taws kub retardant thiab kub kub.

Lub cev pob txha (Skeleton): Hloov cov pob txha hloov pauv ntawm txawv txav ntawm lub cev. Dhau li yog lub rwb thaiv tsev thiab cov khoom txhawb nqa kev sib raug zoo, nws kuj siv lub luag haujlwm ntawm kev txhim kho thiab nrhiav kev txua hluav taws xob tag nrho. Yog li ntawd, cov ntaub qhwv pob zeb yuav tsum tsis txhob tsuas yog raws li qhov yuav tsum tau rwb thaiv tsev, tab sis kuj muaj lub zog tensile zog, thiab kuj dais lub welding tsis kam ntawm pins. Thermal deformation temperature ntawm cov khoom siv pob txha muaj siab tshaj 200 C. Cov khoom yuav tsum yog nplaim qab, thiab nws yuav tsum tau ua tiav zoo thiab yooj yim rau kev ua tiav rau ntau daim duab.

Kho cov txheej txheem txhim kho cov txheej txheem

1, xyuas cov tsos ntawm lub tshuab ua kom pom tias puas muaj yam khoom txawv txav. Xws li seb cov hlau txhuas puas tawg, cov khoom pov tseg, cov khoom pov tseg, qhov kub nyhiab, cov tub ntxhais hlau hlau nplaum yog xoob, silicon hlau ntawv yog xeb, qhov hluav taws xob ntswj raug pom thiab zoo li ntawd.

2. Kev rwb thaiv tsev. Ntsuas qhov tsis sib haum ntawm cov tub ntxhais thiab thawj, thawj thiab theem nrab, cov tub ntxhais thiab theem nrab, lub electrostatic shielding txheej thiab cov theem ob thiab theem nrab nrog lub multimeter R 65 Tsis yog, qhov kev ua haujlwm ntawm lub tshuab hluav taws xob tsis zoo.

3, qhov tshawb tau ntawm lub on-off ntawm lub kauj. Yog hais tias qhov tsis kam ntawm ib tug winding yog infinite, nws qhia tau hais tias lub winding muaj ib tug txhaum txhaum.

4. Txiav cov thawj thiab theem nrab. Cov thawj thiab theem nrab ntawm cov hluav taws xob hloov hluav taws xob feem ntau yog twv ntawm ob sab, thiab qhov sib tw ua ntej tshaj 220 V, thiab qhov nruab nrab qis yog cim nrov ntsuas, xws li 15V, 24V, 35V. Tom qab ntawd txheeb lawv raws li cov cim no.

5. Tsis muaj kev thauj khoom tam sim no

A, ncaj qha ntsuas. Tag nrho cov theem ob lub qhov rooj qhib tag nrho, thiab lub multimeter raug muab tso rau hauv ib qho kev thaiv tam sim no (500mA), uas yog txuas nrog cov thawj sib zog. Thaum lub plhaub ntawm qhov txuas thawj yog ntxig rau 220V AC fais fab, qhov nqi tsis muaj nuj nqi tam sim no yog qhia los ntawm ntau lub suab paj nruag. Cov nqi no yuav tsum tsis pub ntau tshaj li 10% ~ 20% ntawm qhov kev hloov puv tam sim no. Lub cev tsis muaj zog tam sim no ntawm cov hluav taws xob transformers hauv cov khoom siv hluav taws xob yuav tsum nyob ib ncig ntawm 100mA. Yog hais tias nws mus dhau deb, nws qhia tau hais tias tus transformer yog luv luv circuited.

B thiab ntsuas kev ncaj ncees. Hauv thawj tus qauv ntawm lub tshuab hluav taws xob, 10? / 5W resistor txuas nrog koob, thiab cov theem haujlwm tseem tseem khoob. Tig lub multimeter mus rau qhov teeb meem AC voltage. Tom qab fais fab tuag, qhov poob siab ntawm U ntawm ob hnub ntawm kev ua haujlwm R yog ntsuas nrog ob lub cwjmem, thiab tom qab ntawd tsis muaj qhov ntsuas kuv qhov chaw, piv txwv li I-chaw = U / R, yog ua raws Ohm txoj cai. F? Tsis muaj kev kub ntxhov siab. Qhov ntsuas qhov tsis-load voltage (U21, U22, U23, U24) ntawm txhua qhov ntsuas ntsuas nrog ib qhov kev sib txuas ntawm multimeter AC voltage yuav tsum muaj raws li qhov yuav tsum tau ua. Qhov tso cai yuam kev yog feem ntau: high-voltage winding <10%, low-voltage="" winding=""><5%, thiab="" voltage="" qhov="" sib="" txawv="" ntawm="" ob="" qho="" sib="" txawv="" ntawm="" cov="" kab="" nrig="" nrog="" lub="" hauv="" siab=""><>

6. Qhov tso cai kub ntawm qhov cub hluav taws xob me me yog 40 ~ 50 ~ C. Yog tias cov khoom siv thaij duab zoo, qhov kev tso cai kom sov siab tuaj yeem kho tau.

7, ntes thiab txheeb npe rau tib lub npe xaus ntawm txhua qhov sib tw. Thaum siv lub tshuab hluav taws xob, muaj qee zaum ob los sis ntau tshaj lwm cov cua ntsig siv tau ua ke kom thiaj li tau txais qhov yuav tsum tau muaj qhov siab thib ob. Thaum fais fab tuag yog siv rau hauv txoj hauv kev, tib lub npe terminals ntawm txhua tus kab hauv koob yuav tsum txuas nrog kom raug thiab tsis tuaj yeem ua yuam kev. Txwv tsis pub, lub tshuab hloov tsheb yuav tsis ua haujlwm zoo.

8. Tshawb fawb thiab kev ntxub ntxaug ntawm qhov teeb meem luv luv ntawm faiv fab ntawm cov hluav taws xob transformers. Cov tsos mob ntawm cov hluav taws xob tseem ceeb ntawm cov hluav taws xob hloov hluav taws xob yog qhov kub tob hau thiab tsis txawv txav hluav taws xob ntawm kev sib tw zaum ob. Feem ntau, qhov ntau qhov chaw luv luv ntawm cov kev sib tshuam, qhov ntau dua qhov luv luv tam sim no, thiab qhov loj dua cov tshuab hluav taws xob. Ib txoj hauv kev yooj yim los tshawb xyuas thiab txiav txim siab seb puas muaj lub zog ua hluav taws xob muaj qhov ua txhaum cai luv luv yog txhawm rau ntsuas tsis muaj qhov tam sim no (raws li tau piav qhia ntxov). Lub tshuab hluav taws xob nrog luv luv teeb meem faults yuav deb tsawg tshaj li 10% ntawm kev thauj khoom tam sim no. Thaum lub luv luv yog loj heev, lub tshuab hloov ua hluav taws xob yuav kub sai sai hauv li kaum tawm vib voog tom qab tsis muaj hwjchim hlo li. Kov hlau tub ntxhais ntawm tes yuav ua rau lub tshuab ua kom sov siab. Nyob rau lub sij hawm no, tsis muaj kev ntsuas tam sim no tuaj yeem ntsuas, thiab nws yog xaus tias muaj qhov point-short circuit nyob rau hauv qhov kev hloov tshuab.
