Siv lub multimeter los xyuas seb qhov rov qab conduction thyristor puas zoo lossis phem
Siv lub multimeter thiab megohmmeter los xyuas seb qhov rov qab conduction thyristor puas zoo lossis phem. Cov ntsiab lus xeem feem ntau muab faib ua peb yam:
1. xyuas retrograde
Xaiv qhov R × 1 ntau ntawm multimeter, txuas cov kev sim dub coj mus rau K ncej, thiab qhov kev sim liab ua rau A ncej. Tus nqi kuj yuav tsum yog 5 ~ 10Ω. Yog tias qhov tsis kam yog xoom, nws ua pov thawj tias lub diode sab hauv yog luv luv; Yog hais tias qhov tsis kam yog infinite, nws txhais tau hais tias lub diode qhib.
2. Ntsuas qhov pem hauv ntej DC breakover voltage V (BO)
Tom qab txuas lub voj voog, co lub megohmmeter ntawm qhov ntsuas ceev kom RCT tawg nyob rau hauv cov kev taw qhia pem hauv ntej, thiab nyeem V (BO) tus nqi los ntawm DC voltmeter.
3. Txheeb xyuas qhov muaj peev xwm ua tau
Piv txwv: Siv 500-hom multimeter thiab ZC25-3 megohmmeter los ntsuas S3900MF thim rov qab thyristor. Xaiv R × 1k, R × 100, R × 10 thiab R × 1 txhawm rau ntsuas qhov thim rov qab ntawm AK ncej, thiab tib lub sijhawm siv txoj kev nyeem hluav taws xob kom tau txais qhov rov qab voltage VTR ntawm lub diode sab hauv (ua tau lub zog pem hauv ntej ntawm lub diode VF). Tom qab ntawd siv lub megohmmeter thiab multimeter los ntsuas tus nqi V (BO) ntawm 500VDC. Tag nrho cov ntaub ntawv raug muab tso rau hauv Table 1. Qhov no ua pov thawj tias qhov zoo ntawm RCTs kuaj tau zoo.
