Cov tswv yim kho kom hloov pauv cov khoom siv hluav taws xob tsis raug
Hloov fais fab mov yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob ntau yam, thiab nws qhov kev ua tau zoo yog ncaj qha cuam tshuam nrog kev ntsuas cov khoom siv hluav taws xob thiab seb lawv puas tuaj yeem ua haujlwm nyab xeeb thiab ntseeg tau. Vim yog cov khoom tseem ceeb hauv kev hloov pauv hluav taws xob ua haujlwm nyob rau hauv lub xeev hloov pauv siab, kev siv hluav taws xob tsawg, kev hloov pauv siab, thiab tsuas yog 20 feem pua -30 feem pua ntawm qhov ntim thiab qhov hnyav ntawm cov khoom siv hluav taws xob, nws tau dhau los ua cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob tswj tau. Kev saib xyuas ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob ua raws li lub hauv paus ntsiab lus ntawm kev pib ntawm qhov yooj yim mus rau qhov nyuaj. Yeej, nws pib nrog cov khoom siv hluav taws xob, thiab tom qab paub tseeb tias cov khoom siv hluav taws xob zoo li qub, lwm qhov ntawm cov khoom siv tuaj yeem kho. Fais fab mov faults account rau feem ntau ntawm hluav taws xob faults nyob rau hauv cov khoom siv hluav taws xob. Yog li ntawd, nkag siab txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub zog pib, kev paub txog nws tus kheej nrog nws cov kev txawj tu thiab kev ua haujlwm tsis zoo, yog qhov zoo rau kev kho lub sij hawm luv luv ntawm cov khoom siv hluav taws xob tsis zoo thiab txhim kho cov khoom siv tu tus kheej.
1. Tsis muaj qhov tso zis, lub raj muaj kev nyab xeeb yog qhov qub
Qhov tshwm sim no qhia tau hais tias lub zog hloov pauv tsis ua haujlwm lossis tau nkag mus rau hauv lub xeev tiv thaiv. Ua ntej, nws yuav tsum ntsuas seb tus pin pib ntawm lub hwj chim tswj nti muaj qhov pib voltage. Yog tias tsis muaj qhov pib hluav taws xob lossis qhov pib qhov hluav taws xob qis dhau lawm, nws yuav tsum tau xyuas seb qhov pib ua haujlwm puas thiab cov khoom sab nraud ntawm tus pin pib muaj to. Lub sijhawm no, yog tias lub zog tswj cov nti yog qhov qub, qhov txhaum tuaj yeem tshawb pom sai sai los ntawm kev tshuaj xyuas saum toj no. Yog tias muaj qhov pib qhov hluav taws xob, ntsuas seb puas muaj qhov siab lossis qis dhia ntawm qhov tso zis kawg ntawm cov tswj nti thaum lub sijhawm pib. Yog tias tsis muaj qhov dhia, nws qhia tau hais tias cov nti tswj tau puas lawm, muaj teeb meem nrog lub peripheral oscillation Circuit Court Cheebtsam lossis tiv thaiv circuits. Cov nti tswj tau tuaj yeem hloov ua ntej, thiab tom qab ntawd cov khoom siv peripheral tuaj yeem kuaj xyuas; Yog tias muaj qhov dhia, feem ntau yog vim tsis zoo los yog puas lawm hloov raj.
2. Kev nyab xeeb hlawv lossis kib
Feem ntau tshuaj xyuas qhov loj lim capacitor, rectifier choj diodes, hloov raj, thiab lwm qhov chaw ntawm 300V. Yog tias muaj teeb meem nrog kev cuam tshuam los tiv thaiv Circuit Court, nws tuaj yeem ua rau fuse hlawv thiab blackening. Nws yuav tsum tau muab sau tseg tias fuse burning tshwm sim los ntawm hloov raj tawg feem ntau burns tawm tam sim no nrhiav tau resistor thiab lub hwj chim tswj nti. Tsis zoo kub coefficient thermistors kuj tau yooj yim hlawv tawm nrog rau lub fuse.
3. Muaj qhov tso zis hluav taws xob, tab sis cov zis hluav taws xob siab dhau lawm
Hom kev ua txhaum no feem ntau yog los ntawm cov qauv ntsuas hluav taws xob thiab hluav taws xob tswj hluav taws xob. DC tso zis, sampling resistor, yuam kev sampling amplifier xws li TL431, optocoupler, hwj chim tswj nti, thiab lwm yam circuits ua ke ua ib lub voj kaw kaw. Txhua qhov teeb meem ntawm txhua qhov chaw yuav ua rau muaj qhov nce ntawm qhov tso zis hluav taws xob.
4. Yog hais tias qhov tso zis voltage tsawg dhau, dhau li ntawm qhov voltage stabilizing tswj Circuit Court, kuj muaj qee qhov laj thawj uas tuaj yeem ua rau cov zis hluav taws xob tsawg:
ib. Yog hais tias muaj ib tug luv luv Circuit Court txhaum nyob rau hauv lub load ntawm lub hloov fais fab mov (tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm ib tug luv luv Circuit Court los yog tsis ua hauj lwm ntawm lub DC / DC converter), tag nrho cov loads ntawm lub switching fais fab mov Circuit Court yuav tsum tau disconnected kom paub qhov txawv ntawm qhov chaw. hloov fais fab mov Circuit Court los yog load Circuit Court yog faulty. Yog hais tias qhov hluav taws xob tso tawm ntawm lub disconnected load Circuit Court yog ib txwm, nws qhia tau hais tias lub load yog hnyav heev; Yog hais tias nws tseem txawv txav, nws qhia tau hais tias muaj ib tug malfunction nyob rau hauv lub hloov hluav taws xob Circuit Court.
b. Qhov tsis ua haujlwm ntawm rectifier diode thiab lim capacitor ntawm qhov tso zis voltage kawg tuaj yeem txiav txim los ntawm kev hloov pauv.
c. Qhov txo qis hauv kev ua haujlwm ntawm lub raj hloov pauv yuav ua rau muaj kev cuam tshuam tsis zoo ntawm lub raj hloov pauv tsis tuaj yeem ua haujlwm ib txwm muaj, ua rau muaj kev tiv thaiv sab hauv ntawm cov khoom siv hluav taws xob thiab txo cov khoom nqa.
