1. Lub fuse lossis fuse yog tshuab tshuab

Feem ntau kuaj cov diodes ntawm Rectifier Choj, Loj lim caccharacitors, Thiab Tub Tub. Cov teeb meem nrog kev tawm tsam kev tawm tsam yuav ua rau fuses lossis fuses mus hlawv thiab tig dub. Nws yog tsim nyog sau cia tias lub tshuab fuse lossis fuse ua los ntawm kev sib tsoo yog feem ntau nrog kev puas tsuaj rau kev xaiv overcurrent thiab lub zog tswj chip, thiab qhov ntsuas kub tsis zoo coefficient thermistor kuj tseem tsis yooj yim hlawv tawm ua ke nrog lub fuse lossis fuse .

2. Tsis muaj qhov zis, tab sis lub fuse lossis fuse yog li qub

Qhov tshwm sim no qhia tau tias qhov hloov pauv fais fab tsis ua haujlwm, lossis tau nkag mus rau lub xeev tiv thaiv tom qab ua haujlwm. Thawj, ntsuas seb tus pin pib ntawm lub zog tswj chip muaj qhov hluav taws xob pib. Yog tias tsis muaj qhov pib voltage lossis pib voltage qis dhau lawm, Tom qab ntawd xyuas seb puas muaj xau nyob rau hauv lub pib resistor thiab sab nraud cov khoom sib txuas nrog tus lej Pin Start. Yog tias lub zog tswj nti yog ib txwm nyob rau lub sijhawm no, Kuaj cov kev kuaj xyuas saum toj no tuaj yeem nrhiav tau ua txhaum sai sai. Yog tias muaj lub tshuab hluav taws xob pib, ntsuas seb tus tsav tawm ntawm tus pin ntawm tswj chip (Daim duab tuab-zaj duab xis tsis muaj ib txoj kev tsav tsheb pin) muaj qhov siab-theem qis dhia thaum lub sijhawm ntawm lub zog-ntawm. Yog tias tsis muaj kev dhia, Nws txhais tau tias tus tswj chip yog puas, Thiab muaj teeb meem nrog lub peripheral reccuit coents lossis tiv thaiv Circuit Court. Koj tuaj yeem hloov tus tswj chip ua ntej, thiab tom qab ntawd xyuas cov khoom siv uas ntev. Yog tias muaj dhia, Nws yog feem ntau vim tias cov raj hloov hluav taws xob puas yog puas lossis puas.

3. Muaj cov zis hluav taws xob, Tab sis cov zis hluav taws xob yog qhov siab dhau

Qhov kev txhaum no feem ntau yog los ntawm qhov hluav taws xob cov kev cai txwv thiab voltage kev tswj hwm cov kev cai. Peb paub tias kev ncig ua si xws li DC tso zis, Sampling resistor, Yuam kev ua piv txwv amplifier (xws li TL431), Photocoupler thiab Fais Fab Tswj Chip ua ke ua ib lub voj kaw. Qhov hluav taws xob nce.

Rau lub zog hluav taws xob nrog cov kev tiv thaiv kev tiv thaiv, Yog tias cov zis hluav taws xob ntau dhau, Lub Cirvoltage Oferverence Circuit Court yuav ua thawj zaug ua haujlwm. Lub sijhawm no, Qhov Kev Tiv Thaiv Kev Tiv Thaiv Circuit Court tuaj yeem raug txiav tawm los txiav tawm cov kev tiv thaiv kev tiv thaiv, thiab lub ntsiab voltage ntawm lub zog fais fab thaum lub caij pib tuaj yeem ntsuas tau. Yog hais tias ntsuas tus nqi yog siab dua li qub, Cov zis hluav taws xob siab dhau lawm. Hauv kev saib xyuas tiag, Nws yog ib txwm muaj rau kev ntsuas tsis kam hloov, Qhov yuam kev Amplifier lossis PSOCOEDPLER yuav tsum.

4. Cov zis hluav taws xob qis dhau

Raws li kev kho cov kev paub, Ntxiv nrog rau cov hluav taws xob regulator tswj lub voj voos ua rau cov zis hluav taws xob kom qis qis dhau, Muaj lwm cov laj thawj uas yuav ua rau cov zis hluav taws xob kom qis dhau. Muaj ntau cov ntsiab lus hauv qab no.

①THY hloov cov khoom siv fais fab tuag muaj qhov sib txig luv luv. Lub sijhawm no, Txhua lub zog ntawm lub hloov hluav taws xob Circuit Court yuav tsum tau disconnected kom paub qhov txawv txawm tias hloov fais fab khoom siv hluav taws xob tsis zoo lossis lub zog. Yog hais tias lub voltage tawm ntawm lub disconnected load Circuit Court yog ib txwm, Nws txhais tau tias lub nra hnyav dhau. Yog tias nws tseem tsis txawv txav, Nws txhais tau hais tias lub hloov hluav taws xob fais fab yog faulty.

Tam sim no tsis ua haujlwm ntawm lub ntsuas hluav taws xob thiab cov tshuaj lim hluav taws xob ntawm cov zis hluav taws xob tsis tuaj yeem raug txiav txim los ntawm kev hloov pauv.

③the ua tsis tiav kev ua yeeb yam ntawm kev hloov lub raj yuav tsis muaj txiaj ntsig rau qhov tsis ua tiav ntawm lub tshuab hloov pauv ib txwm muaj, uas yuav nce sab hauv kev tawm tsam ntawm lub zog hluav taws xob thiab txo cov load nqa muaj peev xwm.

④ Cov hloov pauv tsis zoo tsis yog ua rau cov zis hluav taws xob kom poob, tab sis kuj ua rau muaj kev zam tsis txaus ntawm txoj hlab, ua rau rov ua kev puas tsuaj rau txoj hlab.

ToveChe lim caub loj Capacitor (uas yog, Lub 300v Lim Cap Capritor) yog tsis zoo, ua rau muaj kev ruaj khov ntawm lub zog hluav taws xob, thiab cov zis hluav taws xob yuav poob thaum lub nra tau txuas.
