Common Fault Analysis ntawm DC Stabilized Power Supply
(1) Kev tshuaj xyuas ntawm kev tswj fais fab
Txhawm rau tiv thaiv overload lossis luv luv Circuit Court, DC stabilized fais fab mov feem ntau txuas nrog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob los ntawm lub fuse, thiab tom qab ntawd txuas mus rau sab nraud Circuit Court los ntawm cov tswv yim thiab cov zis terminals. Ua ntej ntawm tag nrho cov, koj yuav tsum xyuas seb lub fuse yog cua tshuab los yog xoob, seb qhov kev sib txuas ntawm cov input thiab output kab thiab lub fuse yog txhim khu kev qha, seb lub davhlau ya nyob twg yog luv luv los yog xoob, thiab lwm yam. Tom qab kev soj ntsuam, yog tsis muaj. abnormality, qhib lub plhaub ntawm DC stabilized fais fab mov los xyuas seb cov khoom sab hauv puas puas, xws li seb cov resistors, capacitors, diodes, transistors, thiab lwm yam yog tawg, burnt, los yog pwm.
(2) Ntsuas cov zis hluav taws xob rectified
Muaj ib pab pawg ntawm rectified output voltages uas ntsuas tau nyob rau hauv DC stabilized fais fab mov. Kev ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas no tuaj yeem pab txiav txim ntau yam tsis raug hauv Circuit Court. Yog hais tias qhov ntsuas rectified tso zis voltage tus nqi yog txawv txav, ntau yam faults yuav tshwm sim nyob rau hauv lub lag luam ntawm cov tswj fais fab mov. yog li ntawd,
Kev ntsuas qhov ntsuas qhov ntsuas qhov ntsuas hluav taws xob yog qhov tsim nyog.
(3) Ntsuas kev ua haujlwm ntawm cov khoom siv hluav taws xob
Yog hais tias qhov ntsuas rectified tso zis voltage yog ib txwm, tab sis qhov tso zis voltage tsis ruaj khov, ces muaj ib tug txhaum nyob rau hauv lub voltage stabilizing Circuit Court. Vim li no, nws yog ib qho tsim nyog los ntsuas qhov kev ua tau zoo ntawm cov khoom siv siv lead ua xws li kev hloov kho cov raj thiab cov raj amplifier, thiab seb lub capacitor puas puas lawm. Yog tias cov khoom siv hluav taws xob pom tias puas los yog lawv qhov kev ua tau zoo tsis zoo thaum lub sijhawm ua haujlwm no, cov khoom puas yuav tsum tau hloov.
(4) Txheeb xyuas qhov chaw ua haujlwm hauv Circuit Court
Yog hais tias qhov rectified output voltage thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob yog qhov qub, koj yuav tsum xyuas ntxiv seb qhov chaw khiav hauj lwm ntawm lub Circuit Court puas zoo li qub, uas yog, xyuas seb lub transistor puas ua haujlwm hauv cheeb tsam saturation lossis cheeb tsam txiav vim qhov siab. los yog qhov chaw ua haujlwm qis, thiab tsis tuaj yeem ua haujlwm li qub. . Raws li ib txwm muaj, lub transistor ntawm DC stabilized fais fab mov ua hauj lwm nyob rau hauv lub amplification cheeb tsam.
(5) Kev soj ntsuam ntawm kev ua haujlwm Circuit Court
Yog tias tsis muaj teeb meem pom nyob rau hauv cov kauj ruam dhau los, nws yuav tshwm sim los ntawm kev puas tsuaj rau lwm yam hauv Circuit Court. Nyob rau lub sijhawm no, nws yuav tsum ua tib zoo txheeb xyuas txoj hauv kev ua haujlwm ntawm DC tswj cov khoom siv hluav taws xob raws li daim duab kos duab hluav taws xob, nrhiav qhov ua rau tsis ua haujlwm, thiab nrhiav cov khoom puas.
