Hloov cov khoom siv hluav taws xob tswj kev txawj ntse
1. Rau qhov tsis ua hauj lwm ntawm lub fuse hlawv los yog tawg, feem ntau xyuas cov lim loj capacitor ntawm 300V, lub diodes ntawm tus choj rectifier thiab lub raj hloov thiab lwm yam. Qhov teeb meem ntawm kev tiv thaiv kev cuam tshuam Circuit Court kuj yuav ua rau lub fuse hlawv thiab tig dub.
Nco tseg: Lub fuse hlawv vim qhov tawg ntawm lub raj hloov pauv feem ntau yuav kub hnyiab tawm qhov ntsuas tam sim no thiab lub zog tswj nti. Tsis zoo kub coefficient thermistor kuj yooj yim rau hlawv tawm nrog rau fuses.
2. Vim tsis muaj qhov tso tawm, qhov tshwm sim uas lub fuse yog ib txwm qhia tias lub zog hloov hluav taws xob tsis ua haujlwm lossis tau nkag mus rau hauv lub xeev tiv thaiv. Hluav taws xob ntiaj teb
Ua ntej, ntsuas seb tus pin pib ntawm lub hwj chim tswj nti muaj qhov pib-up voltage. Yog tias tsis muaj qhov pib-up voltage lossis qhov pib-up voltage tsawg dhau, xyuas seb qhov pib-up resistor thiab cov khoom txuas nrog tus pin pib yog qhov tam sim no. Yog tias lub hwj chim tswj nti yog qhov qub, qhov kev tshuaj xyuas saum toj no Faults tuaj yeem pom sai.
Yog tias muaj qhov pib-up voltage, ntsuas seb qhov tso zis hluav taws xob ntawm cov khoom siv hluav taws xob tau dhia ntawm qib siab thiab qis thaum lub sijhawm fais fab. Yog tias tsis muaj qhov dhia, nws txhais tau hais tias cov nti tswj tau puas lawm, cov khoom siv hluav taws xob peripheral oscillation Circuit Court lossis kev tiv thaiv Circuit Court muaj teeb meem, thiab kev tswj tau tuaj yeem hloov ua ntej. Chip, thiab tom qab ntawd xyuas cov khoom siv peripheral; yog tias muaj qhov dhia, nws feem ntau yog qhov hloov pauv tsis zoo lossis puas lawm.
3. Rau qhov ua txhaum ntawm cov zis voltage, tab sis cov zis voltage siab dhau lawm, nws feem ntau yog los ntawm voltage stabilization sampling thiab voltage stabilization tswj Circuit Court. (www.dgjs123.com) Lub 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, ib qho teeb meem yuav ua rau cov zis voltage nce.
4. Lub load ntawm cov khoom siv hluav taws xob hloov hluav taws xob muaj qhov cuam tshuam luv luv (tshwj xeeb tshaj yog DC / DC converter yog luv luv lossis muaj kev ua haujlwm tsis zoo, thiab lwm yam). Lub sijhawm no, tag nrho cov khoom siv hluav taws xob hloov hluav taws xob yuav tsum raug txiav tawm kom paub qhov txawv ntawm qhov hloov hluav taws xob hloov hluav taws xob lossis cov khoom siv hluav taws xob tsis raug.
Yog hais tias qhov hluav taws xob tso zis ntawm lub disconnected load Circuit Court yog ib txwm, nws txhais tau hais tias lub load hnyav dhau lawm; lossis yog tias nws tseem txawv txav, nws txhais tau hais tias qhov hloov hluav taws xob hloov hluav taws xob tsis raug.
5. Rau qhov tsis ua hauj lwm ntawm rectifier diode thiab lim capacitor ntawm qhov tso zis voltage kawg, nws tuaj yeem txiav txim los ntawm txoj kev hloov pauv.
Hauv luv luv, kev saib xyuas ntawm kev hloov hluav taws xob tsis ua haujlwm yog ib qho yooj yim lossis nyuaj, tab sis tsuav yog koj nkag siab nws cov khoom tseem ceeb, uas yog, paub meej txog cov qauv thiab cov yam ntxwv ntawm kev hloov hluav taws xob, nws tuaj yeem tshem tawm kev hloov pauv hluav taws xob tsis raug thiab. ua tiav cov nyhuv multiplier.
