Kev Paub Txog

Fais fab Transformer Test thiab kev paub

Qhov teeb meem tseem ceeb nrog lub hwj chim transformers yog sab hauv luv luv circuits. Lub multimeter tuaj yeem siv los kuaj xyuas lub zog hluav taws xob thiab txiav txim siab seb nws puas zoo li qub. Yog hais tias lub rwb thaiv tsev kev ua tau zoo ntawm cov zis transformer degrades los yog muaj ib qho chaw luv luv Circuit Court ntawm lem, cov kab scan tam sim no yuav nce sharply, ua rau cov zis voltage ntawm lub switching fais fab mov poob. Cov kab tso zis transformer tuaj yeem txiav txim siab kom muaj luv luv los ntawm kev ntsuas lub zog hluav taws xob.

A. Kev tshuaj xyuas qhov muag: Tshawb xyuas qhov tshwm sim ntawm qhov hloov pauv kom pom tseeb qhov txawv txav. Txheeb xyuas qhov tawg ntawm coil ua, de-soldering, hlawv cov cim ntawm cov khoom siv insulating, xoob hlau-tightening screws, xeb ntawm silicon steel los xij, raug winding coils, thiab lwm yam teeb meem pom.

B. Rwb thaiv tsev Test: Siv lub multimeter ntawm R × 10k teeb tsa los ntsuas qhov kev tiv thaiv ntawm cov tub ntxhais thiab thawj, thawj thiab theem nrab, cov tub ntxhais thiab txhua theem nrab, electrostatic shielding txheej, thiab cov windings theem nrab. Multimeter pointer yuav tsum qhia infinity. Yog tias tsis yog, lub tshuab hluav taws xob rwb thaiv tsev ua haujlwm tsis zoo.

C. Coil Continuity Test: Teem lub multimeter rau R × 1. Yog hais tias tus nqi kuj ntawm ib tug winding yog infinite, lub winding yog faulty.

D. Kev txheeb xyuas cov kauj ruam tseem ceeb thiab theem ob: Thawj thiab theem nrab pins ntawm lub hwj chim transformer feem ntau nyob rau sab nraud. Thawj winding yog sau nrog 220V, thiab lub thib ob winding yog cim nrog lub ntsuas voltage, xws li 15V, 24V, los yog 35V. Txheeb xyuas lawv raws li cov cim no.

E. Tsis-Load tam sim no nrhiav pom:

(a) Direct Measurement: Qhib tag nrho cov windings theem nrab thiab teem lub multimeter mus rau AC tam sim no (500mA), txuas nws hauv series nrog thawj winding. Thaum thawj winding yog ntsaws rau hauv 220V AC fais fab mov, lub multimeter yuav tso saib qhov tsis muaj load tam sim no. Tus nqi no yuav tsum tsis pub tshaj 10% -20% ntawm lub transformer tag nrho load tam sim no. Rau cov khoom siv hluav taws xob sib xws, qhov tsis muaj qhov tsis muaj peev xwm tam sim no yog li 100mA. Yog tias nws dhau qhov no, lub transformer yuav muaj luv luv Circuit Court.

(b) Kev ntsuas tsis ncaj: Txuas lub 10/5W resistor nyob rau hauv series nrog thawj winding thiab tawm lub thib ob winding kiag li disconnected. Teem lub multimeter rau AC voltage. Tom qab fais fab tuag, ntsuas qhov poob qis (U) hla lub resistor, thiab mam li xam qhov tsis muaj load tam sim no (I) siv Ohm txoj cai: Kuv (tsis muaj-load)=U/R.

F. Tsis-Load Voltage Detection: Txuas lub hauv paus ntawm lub zog hloov hluav taws xob mus rau 220V lub zog hluav taws xob, thiab siv lub tshuab multimeter (teeb rau AC voltage) los ntsuas qhov tsis muaj hluav taws xob (U21, U22, U23, U24) ntawm txhua qhov winding. Qhov ntsuas qhov ntsuas yuav tsum poob rau hauv qhov tau txais: high-voltage winding Tsawg dua los yog sib npaug rau ± 10%, low-voltage winding Tsawg dua los yog sib npaug rau ± 5%, thiab qhov sib txawv ntawm qhov sib txawv ntawm ob pawg ntawm symmetrical windings nrog rau nruab nrab kais. yuav tsum tsawg dua los yog sib npaug rau ± 2%.

G. Kub nce: Tsawg-power transformers feem ntau tso cai rau qhov kub siab ntawm 40 degree txog 50 degree . Yog tias siv cov ntaub ntawv zoo insulating, qhov tso cai kom sov tuaj yeem siab dua.

H. Polarity Detection rau Winding Terminals: Thaum txuas ob los yog ntau tshaj cov windings nyob rau hauv series kom tau qhov xav tau voltage, lub polarity ntawm txhua winding (tib-lub npe terminals) yuav tsum tau muab kev cob cog rua kom raug. Kev sib txuas tsis raug yuav ua rau lub tshuab hluav taws xob ua haujlwm tsis zoo.

I. Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb ntawm Cov Hluav Taws Xob luv luv: Lub hwj chim transformer nrog lub luv luv-circuit txhaum yuav pom cov cua kub ntau dhau thiab txawv txav ntawm qhov nruab nrab winding tso zis voltage. Qhov luv luv-circuited tig nyob rau hauv lub kauj, qhov ntau dua qhov luv-circuit tam sim no thiab kub tsim. Ib txoj hauv kev yooj yim los kuaj xyuas qhov luv luv yog los ntawm kev ntsuas qhov tsis muaj kev thauj khoom tam sim no (raws li tau piav qhia ua ntej). Yog hais tias lub transformer muaj ib tug luv luv Circuit Court, tsis muaj-load tam sim no yuav ho ntau tshaj 10% ntawm tag nrho-load tam sim no. Hauv qhov xwm txheej hnyav, lub tshuab hloov pauv yuav ua kom sov sai sai li ntawm ob peb vib nas this ntawm lub zog, thiab cov tub ntxhais hlau yuav hnov qhov kub ntawm qhov kov. Lub sijhawm no, nws pom tseeb tias lub transformer muaj luv luv Circuit Court.
