Kuaj covfais fab mov transformerSiv ib tug multimeter raws li nram no:
1. Kev ntsuas rwb thaiv tsev: siv lub multimeter R × 10k nres, ntsig txog, los ntsuas qhov kev tiv thaiv ntawm cov tub ntxhais thiab cov thawj, thawj thiab txhua theem nrab, cov tub ntxhais thiab txhua theem nrab, qhov thib ob winding. Multimeter pointer yuav tsum taw tes rau txoj hauj lwm infinity, yog tias tus taw tes txav mus, qhia tias qhov kev ua haujlwm ntawm lub tshuab hluav taws xob tsis zoo.
2. coil on thiab off detection: lub multimeter yuav muab tso rau hauv lub R × 1 thaiv, kuaj, yog hais tias ib tug winding kuj nqi rau infinity, hais tias muaj ib tug Circuit Court-breaking tsis ua hauj lwm ntawm no winding.
3, txheeb xyuas lub hauv paus thiab theem nrab kauj: lub hwj chim transformer thawj thiab thib ob pins feem ntau yog los ntawm ob sab ntawm cov hlau lead, thawj winding ntau cim nrog 220V, lub thib ob winding yog cim tawm cov nqi voltage, xws li 15V, 24V, 35V , thiab lwm yam. Qhia raws li cov cim no.
4. Tsis muaj-load tam sim no nrhiav tau:
* Direct ntsuas txoj kev: tag nrho cov thib ob windings yuav qhib Circuit Court, lub multimeter muab tso rau hauv lub AC tam sim no thaiv (500mA), strung rau hauv thawj winding. Thaum thawj winding ntawm lub ntsaws rau hauv 220V AC mains, lub multimeter yog qhia los ntawm qhov tsis muaj nqi tam sim no. Tus nqi no yuav tsum tsis txhob ntau tshaj 10% mus rau 20% ntawm lub transformer puv load tam sim no.
* Indirect ntsuas txoj kev: nyob rau hauv thawj winding ntawm lub transformer nyob rau hauv series nrog ib tug 10/5W resistor, lub thib ob yog tseem tag nrho tsis-load. Dial lub multimeter rau AC voltage thaiv, los ntawm kev ntsuas ntawm qhov hluav taws xob rau indirectly xam qhov tsis muaj-load tam sim no.
Thaum cov kauj ruam saum toj no tau ua tiav, koj yuav tsum tau sim tag nrho cov kev ua tau zoo ntawm lub hwj chim transformer. Thov nco ntsoov tias nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem kev ua haujlwm nyab xeeb kom tsis txhob muaj hluav taws xob poob lossis lwm yam kev pheej hmoo thaum ua cov kev ntsuas hluav taws xob.
