Kho cov lus qhia rau kev hloov hluav taws xob tsis muaj hluav taws xob tawm
Cov kev kuaj mob yuam kev thiab cov kauj ruam
Thawj txoj haujlwm ntawm kev daws qhov teeb meem no yog los txiav txim siab seb qhov txhaum puas nyob ntawm tus sau ntawm lub raj hloov, lub hauv paus ntawm lub raj hloov lossis lub raj hloov. Txoj kev tshwj xeeb yog ntsuas cov khoom siv thiab lub hauv paus voltage ntawm lub raj hloov. Cov xwm txheej hauv qab no yuav tshwm sim:
(1) Cov khoom siv hluav taws xob ntawm lub raj hloov pauv yog 0v, uas yog 1.4 npaug qis dua lub zog hluav taws xob. Lub raj hloov tsis muaj qhov ua haujlwm voltage. Yog tias qhov hluav taws xob yog 1.4 npaug, nws txhais tau hais tias qhov kev ua haujlwm ntawm qhov hloov pauv yog qhov qub, qhia tias AC220V thiab rectifier lim circuit ua haujlwm ib txwm.
(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 cuam tshuam ntawm lub hauv paus thiab lub emitter puas lawm. Pib Circuit Court, hloov raj emitter thiab lwm yam khoom yuav tsum tau soj ntsuam. Yog tias qhov hluav taws xob nyob nruab nrab ntawm 0.6 thiab 0.7 (nrog rau lub sijhawm ntawm lub hwj chim), nws txhais tau hais tias qhov pib Circuit Court, emitter thiab cov khoom siv ntawm qhov hloov pauv yog qhov qub. Thaum qhov hluav taws xob siab tshaj 0.7V, nws txhais tau hais tias qhov pib Circuit Court yog qhov qub, tab sis cov emitter hlws ris ntawm lub raj hloov los yog nws cov khoom yog qhib Circuit Court los yog resistive. tus nqi nce.
(3) Lub raj hloov pauv muaj cov kev coj ua: lub hauv paus voltage ntawm lub raj hloov pauv yog 0.6 ~ 0.7V, thiab cov khoom siv hluav taws xob ntau dua 250V, qhia tias lub raj hloov tau ua haujlwm. tej yam kev mob. Qhov txhaum tshwm sim hauv qhov kev tawm tswv yim zoo, suav nrog cov lus pom zoo resistor, capacitor, freewheeling diode thiab cov lus pom zoo winding ntawm lub switching transformer thiab lub rooj sib txuas ntawm lawv.
Cov lus qhia txog kev hloov pauv hluav taws xob nrog cov zis hluav taws xob tam sim
(1) Txoj kev thauj khoom tsis raug (2) Ntsuas seb qhov kev tiv thaiv puas puas (3) Txoj kev txiav tawm (4) txoj kev txo qhov hluav taws xob. Thawj lub ntsiab lus yuav tsum tau hais txog lub peev xwm muaj zog ntawm Minrong hloov hluav taws xob, uas tuaj yeem hais tias ua tiav 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 qhov kev thov rau kev nyab xeeb thiab nrhiav cov neeg siv.
Kev ntsuas hluav taws xob txo qis rau txhua qhov kev ua haujlwm hauv Circuit Court. 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 qhia zoo Circuit Court. Muaj ob txoj hauv kev los hloov cov khoom siv hluav taws xob electrolytic hauv cov lus pom zoo ntawm cov khoom siv hluav taws xob hloov tam sim no. Ib qho yog 0.016UF0.039uf capacitor. Tus nqi tsis ua haujlwm yog tsawg heev thiab tuaj yeem raug tshem tawm los ntawm kev saib xyuas. Lwm qhov yog electrolytic capacitor txog 10uF. Lub capacitor no tuaj yeem hloov ncaj qha thaum kho.
(2) Thaum tsis muaj AC voltage regulator, rau kev tiv thaiv overvoltage txhaum, rau kev nyab xeeb, koj tuaj yeem ua ntej hloov cov khoom hnav 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.
