Ntiv kev fauly capacitors feem ntau yog siv siv ntau
Pointer multimeter rau detecting capapror ua txhaum
1. Txhaum kev paub ntawm cov tsis-polar capacitors:
Thaum kuaj, thawj lub tshuab xoom lub pointer multimeter. Tom qab ntawd xaiv RX10Kk Ohm thaj tsam ntawm motimeter ntau yam ntawm lub capacitor tau sim, soj ntsuam qhov kev hloov pauv ntawm tus nqi tiv taus los ntawm compentimeter.
Yog hais tias tus cwj mem txuas tau tam sim ntawd, tus pointer viav vias me ntsis rau sab xis thiab tom qab ntawd rov qab los rau infinity; Tom qab hloov cov kev sojntsuam thiab ntsuas dua, yog tias tus pointer tseem ua viav vias mus rau sab xis thiab rov qab ua rau lub sijhawm sib txuas, nws qhia tias lub capacitor yog ib txwm.
Yog hais tias tus pointer ntawm ntau kev sib tw viav vias mus rau sab xis ze {0}} Nyob rau lub fapacitecture, nws qhia tau tias lub capacitor tau tawg lossis tau tawg.
Yog hais tias tus pointer ntawm multimeter tsis tuaj yeem rov qab mus rau infinity tom qab viav vias mus rau sab xis ntawm lub sijhawm sib txuas, nws qhia tias lub capacitor yog xee hluav taws xob.
Yog hais tias tus pointer ntawm malulitional tsis tsiv mus nyob rau lub sijhawm ntawm kev sib txuas, nws qhia tau tias lub capacitor yog qhib Circuit Court.
2. Txhaum tau pom ntawm electrolytic capacitors:
Electrolytic capacitors yog polarized capacitors. Ua ntej kev xeem, siv cov ntsia hlau los yog txoj kab ncaj nraim rau kev tso cai them nqi hauv lub capacror. Tom qab ntawd txuas cov kev sojntsuam dub ntawm ntau sib deev ntawm lub chaw zoo ntawm lub capacorics thiab kev sojntsuam liab mus rau qhov tsis zoo, thiab saib cov oscillation ntawm lub ntsuas dej taw tes.
Lub sijhawm ntawm kev sib txuas pib, cov mottimeter yuav tsum deflect rau sab xis los ntawm lub kaum sab xis tseem ceeb thiab tom qab ntawd rov qab mus rau sab laug. Txog thaum nws nres ntawm ib qho taw tes, ntsuas ntsuas tus nqi yog lub rwb rwb thaiv tsev tsis kam ntawm lub catchitor. Qhov tsis kam ntsuas tom qab muab cov phiaj xwm tawm ntawm cov phiaj xwm yog qhov rov qab rwb thaiv tsev tiv thaiv ntawm lub capacitor.
Yog tias tus pointer ntawm lub ntsuas ntawm lub ntsuas tsis txav, nws qhia tau tias lub capacitance ntawm tus capacitor no tau ploj mus los yog muaj kev sib tw sab hauv.
Yog tias lub ntsuas ntsuas ntsuas kom ua ntej thiab thim rov qab ntawm lub capacitor tsis kam ntawm lub capacitor yog me me lossis xoom, nws qhia tau tias lub capacitor tau muaj qhov xau dej tsis txaus.
Digital motionims rau detecting capactror ua txhaum
Tso cov digital motimital hauv cov capacitores ntau thiab xaiv cov kev ntsuas kom haum raws li cov hluav taws xob. Tom qab cov capatored tau raug rho tawm tag nrho, ncaj qha Plug ob pins ntawm lub capacitor mus rau hauv qhov kev ntsuas kom ntsuas; Hloov pauv, siv ob txoj kev sim ncaj qha kov tus capactracator tus lej rau kev ntsuas, Capacitor yuav raug tso tawm ncaj qha rau ntawm multimeter.
Thaum ntsuas qhov ntsuas electrolytic nrog cov digital motimeter, tom qab kev soj ntsuam liab yuav tsum txuas nrog tus ncej tsis zoo ntawm lub capacitor. Txij ntawm no, ntsuas kev ntsuas zoo ntawm lub caporitoration ntawm lub capacitor tau, thiab vice versa, ntsuas kev tawm tsam yog lub rwb thaiv tsev tsis zoo.
Kev hloov kho cov txheej txheem rau kev tsim hluav taws xob:
1. Lub peev xwm ntawm tus neeg hloov chaw hloov chaw yuav tsum yog tib yam li ntawm lub capators.
2. Lub zog hluav taws xob siab capacitors tuaj yeem hloov voltage tsis muaj peev xwm tsis tuaj yeem hloov voltitors tsis tuaj yeem hloov voltage siab capacitors.
3. Kev sib txuas ua kom sib txuas ntawm lub peev xwm me me Capacitors tuaj yeem hloov tau lub peev xwm loj censab Capitors; Loj muaj peev xwm capacitors nyob rau hauv series tuaj yeem hloov chaw muaj peev xwm me me Capacitors.
4. Electrolytic capacitors hauv cov kab ntawv rov qab tuaj yeem siv los hloov cov chaw tsis-polar capacitors.
5. Rau cov nquag nquag oscillation capacitors thiab lub zog hluav taws xob lim dej capacitors, capacitors siv tau tsis tuaj yeem siv rau hloov chaw.
