Kev kuaj mob thiab kev saib xyuas kev ntsuas thaum ntsib qhov txawv txav ntawm qhov hluav taws xob hloov hluav taws xob
1. Kev tu cov txuj ci rau kev hloov hluav taws xob hloov hluav taws xob tsis muaj qhov tso tawm
Txoj kev kuaj mob yuam kev thiab cov kauj ruam
Lub luag haujlwm tseem ceeb ntawm hom kev daws teeb meem no yog los txiav txim siab seb qhov txhaum puas yog nyob rau hauv lub collector ntawm lub hloov, lub hauv paus ntawm lub hloov los yog hloov. Txoj kev tshwj xeeb yog ntsuas cov khoom siv thiab lub hauv paus voltage ntawm lub raj hloov. Muaj ob peb lub sijhawm ua tau:
(1) Cov khoom siv hluav taws xob ntawm lub raj hloov pauv yog 0v, uas yog 1.4 npaug qis dua li ntawm lub ntsiab. Lub raj hloov pauv tsis muaj qhov ua haujlwm li qub. Yog tias qhov hluav taws xob yog 1.4 npaug, nws txhais tau hais tias qhov ua haujlwm voltage ntawm cov khoom siv hluav taws xob hloov hluav taws xob yog qhov qub, thiab nws txhais tau hais tias AC220V thiab kev hloov kho thiab lim dej ua haujlwm zoo li qub.
(2) Lub hauv paus voltage ntawm lub raj hloov pauv yog 0V (nrog rau lub sijhawm pib). Qhov no qhia tau hais tias qhov pib Circuit Court tsis muab qhov pib (ua) qhov hluav taws xob rau lub hauv paus ntawm lub raj hloov, lossis cov khoom muaj feem cuam tshuam ntawm lub hauv paus thiab cov emitter raug puas tsuaj, thiab pib Circuit Court, lub emitter ntawm lub raj hloov thiab lwm yam khoom. yuav tsum tau kuaj. Yog tias qhov hluav taws xob nyob nruab nrab ntawm 0.6 thiab 0.7 (nrog rau lub sijhawm ntawm lub hwj chim), nws qhia tau hais tias qhov pib-up Circuit Court, emitter thiab cov khoom siv ntawm qhov hloov pauv yog qhov qub. Thaum qhov hluav taws xob siab tshaj 0.7V, nws qhia tau hais tias qhov pib-up Circuit Court yog ib txwm, tab sis cov emitter junction ntawm lub hloov raj los yog nws cov khoom yog qhib Circuit Court los yog tsis kam ntawm tus nqi nce.
(3) Lub raj hloov pauv muaj qhov ua tau zoo: lub hauv paus voltage ntawm lub raj hloov pauv yog 0.6 ~ 0.7V, thiab cov khoom siv hluav taws xob ntau dua 250V, uas txhais tau hais tias lub raj hloov muaj kev ua haujlwm. Qhov txhaum tshwm sim hauv qhov kev tawm tswv yim zoo hauv Circuit Court, suav nrog cov lus pom zoo resistors, capacitors, freewheeling diodes, thiab cov lus qhia zoo windings ntawm switching transformers thiab cov ntawv txuas ntawm lawv.
Thib ob, hloov cov khoom siv hluav taws xob tam sim no qhov hluav taws xob tso tawm cov kev txawj ntse
(1) Dummy load txoj kev
(2) Ntsuas seb cov khoom tiv thaiv puas puas
(3) Txoj kev txiav tawm
(4) Txoj kev nqis tes ua. Thawj lub ntsiab lus yuav tsum tau hais txog lub peev xwm muaj zog ntawm Minrong hloov hluav taws xob, uas tuaj yeem hais tau raws li kev nyab xeeb thiab kev nrhiav. Nws tuaj yeem hais tias Minrong hloov hluav taws xob muaj qhov zoo ntawm kev ua haujlwm siab, kev nyab xeeb siab, tsis tshua muaj kev poob, thiab lwm yam, uas yog sib cais los ntawm kev muaj zog pab. Ib yam li ntawd, lub peev xwm ua tau zoo ntawm Minrong hloov hluav taws xob yog qhov sib cais los ntawm Minrong Electric txoj kev ua raws li kev nyab xeeb thiab kev nrhiav neeg siv.
Txhua qhov kev ua haujlwm Circuit Court step-down nrhiav kom tau. Tom qab txiav txim siab qhov twg ntawm qhov hloov hluav taws xob hloov pauv tsis raug los ntawm cov txheej txheem saum toj no, cov txheej txheem tshuaj xyuas rau txhua ntu yog raws li hauv qab no:
(1) Txheeb xyuas qhov ntsuas pulse width modulation circuit thiab cov lus pom zoo Circuit Court. Muaj ob txoj hauv kev los hloov cov electrolytic capacitor hauv qhov kev tawm tswv yim zoo ntawm cov khoom siv hluav taws xob hloov tam sim no, ib qho yog 0.016UF0.039uf Tus nqi tsis ua haujlwm ntawm lub capacitor yog tsawg heev thiab tuaj yeem raug tshem tawm. los ntawm kev tshuaj xyuas. Lwm qhov yog electrolytic capacitor nyob ib ncig ntawm 10uF. Lub capacitor no tuaj yeem hloov ncaj qha thaum lub sijhawm kho dua.
(2) Thaum tsis muaj AC voltage regulator, rau overvoltage tiv thaiv faults, rau kev nyab xeeb yog vim li cas, koj tuaj yeem ua ntej hloov qhov tsis muaj zog hauv Circuit Court tsim los ntawm kev ua haujlwm voltage ntawm pulse width modulation circuit, uas yog, lim capacitor ( los ntawm ob peb microfarads mus rau 100uF electrolytic capacitor) kom pom tias lub zog hloov hluav taws xob rov qab mus rau qhov qub.
3. Kev tu cov txuj ci rau cov zis hluav taws xob tsawg ntawm kev hloov hluav taws xob
Cov txheej txheem thiab cov kauj ruam ntawm kev kuaj mob
(1) Kev kuaj xyuas tsis raug los ntawm kev ntsuas cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob
(2) Ntsuas qhov hluav taws xob ntawm txhua qhov tso zis hluav taws xob ntawm lub zog hloov hluav taws xob los txiav txim qhov txhaum.
(3) Qhov tso zis hluav taws xob poob yog qhov loj dua ntawm kab, thiab qee qhov tso zis hluav taws xob poob qis dua li ntawm kab
