Lub zog thiab lwm yam ntxwv ntawm tus hloov pauv tau qhia nyob rau ntawm cov ntaub ntawv txuas nrog lub khw tsim khoom rau txhua lub cuab yeej. Tab sis dab tsi yog tias daim phiaj no npog lossis ploj? Thaum hom transformer thiab nws cov tsis paub, lawv tuaj yeem raug txiav txim siab siv lub tshuab ntsuas thiab ntsuas yooj yim.

Cov Lus Qhia
Kauj ruam 1
Siv cov multimeter (autometer), txiav txim siab qhov chaw nyob ntawm cov terminals ntawm tag nrho cov windings ntawm transformer thiab ntsuas lawv qhov kev tawm tsam. Thawj kauj ntoo yog tus uas muaj qhov tawm tsam zoo tshaj plaws. Qhov no yog txoj kev yooj yim tshaj plaws los txiav txim siab thawj qhov kev sib tw.
Kauj ruam 2
Yog tias qhov kuaj xyuas qhov hloov pauv muaj ntau tshaj ob qhov cua, thawj zaug yuav tsum tau muab cov winding uas tsis tshua muaj kev tiv thaiv yog qhov sib thawj. Thov siv hluav taws xob qis AC (xws li 10 volts) rau nws siv lub zog hluav taws xob. Ntsuas qhov ntsuas ntawm txhua qhov windings. Raws li cov txiaj ntsig ntawm kev ntsuas, ntsuas qhov tseeb qhov tseem ceeb ntawm kev hloov pauv ntawm qhov hloov pauv. Ntsuam xyuas koj tus kheej los ntawm rov ntsuas ntsuas thaum siv ntau voltage rau windings.
Kauj ruam 3
Tom qab ntawd, saib xyuas qhov sib txawv nruab nrab ntawm lub kauj thiab sib nqus Circuit Court, cua ib lub xaim me me rau ntawm qhov windings, yog li tsim dua lwm qhov winding. Qhov ntau tig ntawm cov hlau yog qhov txhab, ntau dua qhov tseeb ntawm qhov kawg qhov kawg yuav yog. Yog tias tsis muaj chaw nyob hauv lub tshuab pauv hloov rau lwm txoj kev siv cua, siv ib feem ntawm qhov muaj tam sim no sab nrauv winding. Txhawm rau ua qhov no, ua tib zoo tshem cov txheej sab nrauv sab hauv ntawm lub kauj kom muaj kev nkag tau yooj yim mus rau lub txheej kawg ntawm cov kab uas twb muaj lawm.
Kauj ruam 4
Nrhiav qhov kawg ntawm qhov qhib winding thiab suav txhua cov lej lem los ntawm nws. Nco ntsoov tias tus lej sib lem no cuam tshuam ncaj qha rau cov txiaj ntsig kev xam. Ntawm lub voj kawg, ua tib zoo tev tawm ntawm qee qhov txha hniav laus. Tau npaj rau multimeter, nrog ib qho ntawm nws cov coj, kov lub cev liab qab ntawm winding siv rab koob xaws rau qhov no. Tom qab thov voltage rau thawj winding, ntsuas qhov voltage ntawm winding koj tsim los yog ntawm suav lem.
Kauj ruam 5
Laij suav pes tsawg tus lem lem hauv txhua qhov cua. Txhawm rau ua qhov no, ntau qhov ntsuas hluav taws xob nyob ntawm qhov ntsuas cua los ntawm tus xov tooj ntawm lem tau los ntawm koj tus kheej lossis suav rau hauv txheej kawg. Faib qhov tshwm sim los ntawm qhov ntsuas voltage thov rau kev kuaj ntsuas.
Kauj Ruam 6
Tom qab suav cov naj npawb ntawm cov lem rau txhua qhov qauv transformer windings, laij ib qho chaw ib ntu ntawm qhov sib nqus. Txhawm rau ua qhov no, ntau qhov ntau ntawm cov xov hluav taws xob nyob rau ntawm thawj qhov sib npaug ntawm 50 thiab faib los ntawm tus naj npawb ntawm lem ntawm qhov winding. Qhov tshwm sim yuav yog thaj chaw ntawm qhov tseem ceeb ntawm lub sib nqus Circuit Court, qhia nyob rau hauv square centimeters.
Kauj Ruam 7
Txhawm rau suav lub zog ntawm lub zog tshawb xyuas qhov hloov pauv, square qhov tau txais qhov chaw ntu ntawm thaj chaw sib nqus thiab sib faib los ntawm 1, 3. Qhov tshwm sim yuav qhia lub zog ntawm cov cuab yeej hauv watts.
