Feem ntau tsis ua hauj lwm ntawm cov tswj fais fab mov units
tshuab fuse
Feem ntau, lub tshuab hluav taws xob qhia tau hais tias muaj teeb meem nrog cov kab hluav taws xob sab hauv ntawm cov khoom siv hluav taws xob. Txij li thaum lub zog hluav taws xob ua haujlwm ntawm high voltage thiab high tam sim no, kev hloov pauv thiab nce siab hauv daim phiaj hluav taws xob yuav ua rau cov khoom siv hluav taws xob tam sim no nce sai sai thiab ua rau lub fuse tawg. Lub hom phiaj yuav tsum tau xyuas lub rectifier diode, high-voltage lim electrolytic capacitor, inverter fais fab hloov raj, thiab lwm yam. ntawm lub hwj chim input kawg los xyuas seb cov khoom no puas puas lawm, qhib Circuit Court, puas, thiab lwm yam. Yog hais tias lub fuse yog kiag li tshuab. , koj yuav tsum xub xyuas cov khoom sib txawv ntawm lub rooj tsav xwm hauv Circuit Court kom pom tias cov tsos ntawm cov khoom no raug hlawv thiab seb cov electrolyte tau dhau lawm. Yog tias tsis pom cov xwm txheej saum toj no, siv lub tshuab multimeter los ntsuas seb lub raj hloov pauv puas muaj qhov tawg lossis luv luv. . Kev saib xyuas tshwj xeeb yuav tsum tau them rau: thaum pom tias muaj kev puas tsuaj, koj yuav tsum tsis txhob tig ncaj qha tom qab hloov nws. Qhov no tuaj yeem ua rau cov khoom hloov pauv puas vim tias lwm cov khoom siv hluav taws xob siab tseem faulty. Tag nrho cov khoom siv high-voltage hauv Circuit Court saum toj no yuav tsum tau tshuaj xyuas ib zaug. Tsuas yog tom qab kuaj xyuas thiab ntsuas qhov ua txhaum ntawm lub tshuab fuse raug tshem tawm tag nrho.
Feem ntau ua txhaum ntawm cov khoom siv fais fab
Tsis muaj DC voltage tso zis los yog tsis ruaj tsis khov voltage tso zis
Yog hais tias lub fuse tsis zoo, yuav tsis muaj DC voltage tso tawm ntawm txhua theem nyob rau hauv load. Qhov xwm txheej no feem ntau tshwm sim los ntawm cov laj thawj hauv qab no: qhib Circuit Court lossis luv luv hauv lub zog hluav taws xob, tsis ua haujlwm ntawm overvoltage thiab overcurrent tiv thaiv Circuit Court, pab fais fab mov tsis ua hauj lwm, oscillation circuit tsis ua hauj lwm, overload ntawm lub hwj chim mov, rectifier diode nyob rau hauv lub siab. -frequency rectifier lim Circuit Breakdown, lim capacitor to, thiab lwm yam. Tom qab ntsuas cov khoom thib ob nrog lub tshuab multimeter thiab txiav txim siab tawm qhov kev puas tsuaj ntawm high-frequency rectifier diode thiab load luv Circuit Court, yog tias cov zis yog xoom nyob rau lub sijhawm no, nws yog paub tseeb tias cov tswj Circuit Court ntawm lub hwj chim mov yog faulty. Yog tias muaj qee qhov tso tawm hluav taws xob, nws txhais tau hais tias lub hauv ntej-kawg Circuit Court ua haujlwm ib txwm, thiab qhov txhaum nyob rau hauv high-frequency rectifier thiab lim circuit. Lub high-frequency lim Circuit Court mas muaj ib tug rectifier diode thiab ib tug low-voltage lim capacitor los tsim ib tug DC voltage tso zis. Kev tawg ntawm lub rectifier diode yuav ua rau lub voj voog tsis muaj qhov hluav taws xob tawm, thiab cov dej ntws tawm ntawm lub lim capacitor yuav ua rau cov zis tsis ruaj khov thiab lwm yam tsis raug. Cov khoom puas tuaj yeem raug kuaj pom los ntawm kev ntsuas qhov sib thooj nrog lub multimeter.
Tsis zoo zog load peev
Lub peev xwm tsis zoo ntawm cov khoom siv hluav taws xob yog qhov ua txhaum ntau. Nws feem ntau tshwm sim hauv cov khoom siv hluav taws xob ua haujlwm qub lossis ua haujlwm ntev. Qhov laj thawj tseem ceeb yog vim li cas cov khoom muaj kev laus, lub raj xa hluav taws xob tsis ruaj khov, thiab cov cua sov tsis tau tawg rau lub sijhawm. Koj yuav tsum tsom mus xyuas seb lub Zener diode puas kub thiab tawg, lub rectifier diode puas, lub high-voltage lim capacitor puas, thiab lwm yam.
