Feem ntau faults thiab txij nkawm ntawm kev lag luam induction cookers

Feem ntau muaj peb yam txhaum hauv kev lag luam induction cookers:
1. Kev tawg - hlawv fuse thiab IGBT. Qhov tshwj xeeb tshwm sim yog tias tsis muaj lus teb thaum lub tshuab hluav taws xob, thiab tag nrho lub tshuab tsis ua haujlwm. Thaum peb qhib lub tshuab, peb yuav pom tias lub fuse tau tawg, thiab nws tau tawg heev heev. Lub iav phab ntsa ntawm lub fuse tau blackened tawm. Peb tau tshawb xyuas ntxiv thiab pom tias IGBT nyob rau hauv lub tshuab hluav taws xob loj kuj tau tawg, qee zaum txawm hlawv tus choj rectifier. Txawm li cas los xij, tus choj rectifier muaj zog ntau dua li IGBT, thiab feem ntau, tsuas yog IGBT raug hlawv.
Hauv qhov xwm txheej no, peb yuav tsum tsis txhob maj hloov cov khoom thiab kuaj lub tshuab. Kuj xyuas seb puas muaj lwm yam puas lawm. Thaum kuv ntsib qhov teeb meem no, kuv yuav ntsuas tag nrho cov kev tawm tsam ntawm lub cev loj nrog qhov muaj txiaj ntsig zoo hauv Circuit Court, nrog rau ob lub transistors (80508550) uas tsav IGBT. Kuv tseem yuav ua tib zoo saib ntawm 300V lim capacitor thiab 0.33uF resonant capacitor kom pom tias lawv puas. Yog tias tag nrho cov no tsis zoo, hloov tag nrho cov khoom puas tsuas yog IGBT. Lub sijhawm no, lub zog ntawm lub tshuab ntsuas thiab ntsuas seb puas ntxiv 5V, ntxiv rau 15V, lossis ntxiv rau 18V, thiab B ncej 0V ntawm IGBT yog qhov qub. Tsuas yog thaum cov voltages zoo li qub tuaj yeem ntsia tau IGBT. Qhov no tuaj yeem tshem tawm feem ntau ntawm lub tshuab tawg ua txhaum.
2. Lub tshuab tag nrho tsis teb, tab sis tsis muaj kev sim tawg. Tag nrho lub tshuab tsis ua haujlwm. Tom qab disassembled lub induction cooker, nws tau pom tias lub fuse tsis zoo. Qhov teeb meem no feem ntau yog tshwm sim los ntawm lub zog hloov pauv nti ntawm lub induction cooker raug hlawv. Nws feem ntau tsim ib qhov hluav taws xob ntawm 18V, uas tom qab ntawd hloov mus rau hauv qhov hluav taws xob ntxiv 5V rau CPU ua haujlwm. Yog tsis muaj ntxiv 5V, CPU yuav tsis ua haujlwm, thiab tau kawg, tag nrho lub tshuab yuav tsis ua haujlwm. Cov hom chips hauv induction cookers feem ntau yog siv, xws li viper12a, viper22a, thx203h, thiab lwm yam. Kuaj lub peripheral ntawm lub hwj chim hloov dua siab tshiab nti kom pom tias muaj cov khoom me me uas puas lawm. Yog tias muaj, hloov lawv.
3. Nws tuaj yeem qhib tau, tab sis kev pom cov lej txhaum yuav tsum nkag siab lub ntsiab lus ntawm cov lej ua ntej lub hom phiaj kev saib xyuas. Muaj ntau ntau qhov txhaum cai rau induction cookers online, thiab peb tuaj yeem siv tag nrho lawv. Hom kev ua txhaum no feem ntau yog tshwm sim los ntawm kev hloov pauv ntawm qhov kev tiv thaiv ntawm cov neeg muaj qhov tseem ceeb ntawm kev tiv thaiv loj thiab cov duab loj, uas tuaj yeem ntsuas ib qho los ntawm ib qho. Yog tias muaj kev hloov pauv, hloov lawv. Nyob rau tib lub sijhawm, xyuas cov transformer, 300v / 5uF capacitor, thermistor thiab tsuas yog potentiometer hauv induction cooker. Tsuav yog pom cov chaw no, tej kev txhaum no feem ntau yuav raug tshem tawm. Ob peb kuj tuaj yeem tshwm sim los ntawm kev puas tsuaj rau LM339, uas tuaj yeem tshawb xyuas los ntawm kev hloov pauv.
Lub 4 lub luag haujlwm tsis zoo, thiab qee qhov tsis teb thaum nias lub zog khawm. Hom malfunction no yog qhov zoo tshaj plaws kho, feem ntau yog vim lub pob tawg los yog lub pob board yog qias neeg lossis hluav taws xob. Hloov khawm lossis ntxuav lub pob khawm tuaj yeem daws qhov teeb meem no.
Kev ua txhaum xws li tawg 5 CPU feem ntau tsis tuaj yeem kho, thiab nws yog qhov zoo tshaj kom tsis txhob nkim sij hawm vim tias cov CPUs no nyuaj kom tau txais.
6. Tsis muaj cua sov lossis cua sov tsis sib xws. Hom kev txhaum no tsis yooj yim kho. Qhov ntsuas kub ntsuas ntsuas, synchronous oscillation circuits, IGBT drives, IGBT C siab voltage tiv thaiv circuits, tam sim no nrhiav pom circuits, PWM modulation circuits, thiab CPU circuits tej zaum yuav tag nrho muaj feem xyuam rau hom kev txhaum no. Kev kho tej yam tsis zoo no yog qhov kev sim ntawm peb lub siab ntev.

Cov ntsiab lus saum toj no yog tsim los ntawm Superb heater Company, super heater. Kev tsim khoom tseem ceeb: cov khoom siv cua sov, ntsuas kub, cov khoom siv, cov khoom siv, thiab cov khoom siv raw xws li tubular rhaub, tubular rhaub, siv cua sov, ceramic rhaub, silicone roj hmab rhaub, thermocouples, thiab lwm yam.
