Kev tshuaj xyuas ntawm Induction Melting Rauv Repairing Tas Capacitor

(1) Tshawb xyuas cov capacitors me me hauv qab 10pF. Vim hais tias lub peev xwm ntawm qhov ruaj khov capacitor qis dua 10pF yog qhov tsawg dhau, thaum ntsuas nrog multimeter, nws tsuas yog tuaj yeem kuaj xyuas kom zoo rau kev xau, sab hauv luv luv lossis tawg. Thaum ntsuas, koj tuaj yeem xaiv lub multimeter R × 10k thaiv, thiab siv ob lub meter cwjmem los txuas ob tus pins ntawm lub capacitor random, thiab qhov kev tawm tsam yuav tsum tsis muaj kawg. Yog tias qhov ntsuas ntsuas tus nqi (tus pointer swings mus rau sab xis) yog xoom, nws txhais tau hais tias lub capacitor puas los ntawm kev xau lossis kev poob siab.

(2) Tshawb xyuas seb lub 10pF ~ 1000uF tsau capacitor yog them, thiab tom qab ntawd txiav txim nws qhov zoo, lub multimeter xaiv Rx1k iav. Yog tias tus nqi B ntawm ob lub triodes ntau dua 100, thiab qhov nkag mus rau tam sim no yuav tsum me me, 3Dc6 thiab lwm hom triodes tuaj yeem siv los tsim cov raj sib xyaw. Cov kev xeem liab thiab dub ua rau ntawm lub multimeter txuas nrog rau lub emitter e thiab collector c ntawm cov raj sib xyaw. Vim lub amplification nyhuv ntawm composite transistor, lub them thiab tawm thiab lub hwj chim txheej txheem ntawm lub capacitor nyob rau hauv lub xeem yog amplified, thiaj li hais tias tus pointer viav vias ntawm lub multimeter yog nce. Yog li kom pab tau kev soj ntsuam. Nws yuav tsum tau muab sau tseg tias nyob rau hauv lub xeem ua hauj lwm, tshwj xeeb tshaj yog thaum ntsuas capacitors nrog me me capacitance, tus pin tiv tauj cov ntsiab lus ntawm lub capacitor nyob rau hauv kev ntsuam xyuas yuav tsum tau rov sib pauv, thiaj li hais tias lub zog ntawm tus pointer ntawm lub multimeter yuav pom meej meej. ,

(3) Rau cov kab hluav taws xob ruaj khov siab dua 1000uF, Rx10k cov ntaub ntawv ntawm multimeter tuaj yeem siv los ntsuas ncaj qha seb lub capacitor puas muaj cov txheej txheem them nyiaj, thiab seb puas muaj qhov luv luv hauv Circuit Court lossis to, thiab lub peev xwm ntawm lub capacitor tuaj yeem kwv yees raws li qhov loj ntawm tus pointer viav vias mus rau sab xis.
