transformer daim ntawv

Taw qhia rau cov kev paub yooj yim ntawm transformer

Lub transformer yog tsim los ntawm ib tug hlau core (los yog magnetic core) thiab ib kauj. Lub kauj muaj ob los yog ntau tshaj windings, uas cov winding txuas nrog lub hwj chim mov yog hu ua thawj kauj, thiab lwm yam windings yog hu ua thib ob kauj.

1, Kev faib tawm

Kev faib tawm los ntawm hom txias: hom qhuav (tus kheej txias) transformer, roj raus (tus kheej txias) transformer thiab fluoride (evaporative txias) transformer.

Muab faib los ntawm txoj kev ya raws-pov thawj: qhib hom transformer, potted hom transformer thiab kaw hom transformer.

Kev faib tawm raws li cov tub ntxhais hlau lossis cov qauv coil: core transformer (ntxig core, C-hom core thiab ferrite core), plhaub transformer (ntxig core, C-hom core thiab ferrite core), nplhaib transformer thiab hlau ntawv hlau transformer.

Kev faib tawm raws li tus naj npawb ntawm cov theem fais fab: ib-theem transformer, peb-theem transformer thiab multi-theem transformer.

Kev faib tawm los ntawm kev siv: fais fab transformer, voltage regulating transformer, audio transformer, intermediate zaus transformer, high zaus transformer thiab mem tes transformer.

2, Cov yam ntxwv tsis zoo ntawm lub zog transformer

1. Kev khiav hauj lwm zaus

Qhov poob ntawm transformer core yog ze ze rau qhov zaus, yog li nws yuav tsum tau tsim thiab siv raws li kev siv zaus, uas yog hu ua kev ua haujlwm zaus.

2. Rated zog

Nyob rau hauv qhov teev zaus thiab voltage, lub transformer tuaj yeem ua haujlwm ntev yam tsis muaj ntau tshaj qhov tso zis hluav taws xob ntawm qhov ntsuas kub nce.

3. Rated voltage

Nws hais txog qhov hluav taws xob tso cai rau siv rau ntawm lub coil ntawm lub transformer, uas yuav tsum tsis txhob ntau tshaj qhov teev tus nqi thaum ua haujlwm.

4. Voltage piv

Nws hais txog qhov piv ntawm thawj qhov hluav taws xob mus rau theem nrab voltage ntawm transformer, uas txawv ntawm qhov tsis muaj qhov hluav taws xob voltage piv thiab load voltage piv.

5. Tsis muaj load tam sim no

Thaum lub thib ob ntawm lub transformer yog qhib Circuit Court, tseem muaj ib tug tej yam tam sim no nyob rau hauv thawj, uas yog hu ua tsis muaj-load tam sim no. Tsis muaj load tam sim no muaj magnetization tam sim no (tsim magnetic flux) thiab hlau poob tam sim no (ua los ntawm core poob). Rau 50Hz fais fab transformer, qhov tsis muaj-load tam sim no yog qhov sib npaug ntawm cov hlau nplaum tam sim no.

6. Tsis muaj load poob

Nws yog hais txog lub zog poob ntsuas ntawm lub hauv paus thaum lub thib ob ntawm lub transformer yog qhib Circuit Court. Qhov kev poob tseem ceeb yog qhov poob ntawm qhov tseem ceeb, ua raws li qhov poob (tooj liab plam) tshwm sim los ntawm qhov tsis muaj kev thauj khoom tam sim no ntawm cov thawj coil tooj liab tsis kam, uas yog me me heev.

7. Kev ua haujlwm zoo

Yog qhov feem pua ​​​​ntawm qhov piv ntawm lub zog theem nrab P2 rau lub zog thawj P1. Feem ntau, qhov siab dua qhov ntsuas lub zog ntawm lub transformer, qhov ua tau zoo dua.

8. Rwb thaiv tsev tsis kam Qingzhou thoob ntiaj teb electronics

Nws qhia txog kev ua haujlwm rwb thaiv tsev ntawm txhua kauj ntawm transformer thiab nruab nrab ntawm txhua lub kauj thiab cov tub ntxhais hlau. Lub rwb thaiv tsev tiv thaiv yog cuam tshuam nrog kev ua haujlwm, kub thiab av noo ntawm cov ntaub ntawv insulating siv.

3, Cov yam ntxwv tsis zoo ntawm lub suab zaus transformer thiab siab zaus transformer

1. zaus teb

Nws yog hais txog tus yam ntxwv uas cov zis hluav taws xob theem nrab ntawm lub transformer hloov nrog cov zaus ua haujlwm.

2. Passband

Yog hais tias qhov tso zis voltage ntawm transformer ntawm qhov nruab nrab zaus yog U {{{0}}}, qhov ntau zaus thaum cov zis voltage (input voltage tseem tsis hloov) poob rau 0.707u0 hu ua passband B ntawm lub transformer.

3. Thawj thiab theem nrab impedance piv

Thawj thiab theem nrab impedance ntawm transformer txuas nrog qhov tsim nyog impedance RO thiab RI kom phim cov thawj thiab theem nrab impedance ntawm transformer, ces qhov piv ntawm RO thiab RI yog hu ua thawj thiab theem nrab impedance piv. Nyob rau hauv cov ntaub ntawv ntawm impedance txuam.
