Feem ntau faults ntawm tswj fais fab mov
tshuab fuse
Feem ntau, lub tshuab hluav taws xob qhia tias muaj teeb meem nrog cov kab hluav taws xob sab hauv ntawm cov khoom siv hluav taws xob. Vim tias cov khoom siv hluav taws xob ua haujlwm nyob rau hauv lub xeev ntawm high voltage thiab high tam sim no, qhov hloov pauv thiab surge ntawm daim phiaj voltage yuav ua rau cov tam sim no nyob rau hauv lub hwj chim mov yuav nce instantaneously thiab ua rau lub fuse tshuab. Lub hom phiaj yuav tsum tau xyuas cov rectifier diodes ntawm lub hwj chim input kawg, high-voltage lim electrolytic capacitors, inverter fais fab hloov raj, thiab lwm yam., thiab xyuas seb cov khoom no puas muaj kev puas tsuaj, qhib Circuit Court, puas, thiab lwm yam. Yog hais tias lub fuse yog tseeb. tshuab, koj yuav tsum xub xyuas cov khoom ntawm lub rooj tsav xwm hauv Circuit Court kom pom tias cov tsos ntawm cov khoom no puas tau hlawv lossis yog cov electrolyte dhau lawm. Yog tias qhov xwm txheej saum toj no tsis pom, 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 qee yam khoom puas lawm, nws yuav tsum tsis txhob muab tso ncaj qha tom qab hloov. Qhov no yuav ua rau muaj kev puas tsuaj rau cov khoom hloov pauv vim yog lwm cov khoom siv hluav taws xob uas tseem muaj qhov tsis raug. Tag nrho cov high-voltage Cheebtsam nyob rau hauv lub Circuit Court saum toj no yuav tsum muaj kev nyab xeeb tom qab kuaj xyuas thiab ntsuas, qhov txhaum ntawm lub tshuab fuse tuaj yeem txiav tawm tag nrho.
Tsis muaj DC voltage tso zis los yog tsis ruaj tsis khov voltage tso zis
Yog tias lub fuse tsis zoo, tsis muaj qhov tso tawm ntawm DC voltage ntawm txhua theem hauv qab load. Qhov xwm txheej no feem ntau yog tshwm sim los ntawm cov laj thawj hauv qab no: qhib Circuit Court thiab luv luv hauv lub zog hluav taws xob, tsis ua haujlwm ntawm overvoltage thiab overcurrent tiv thaiv Circuit Court, tsis ua haujlwm ntawm cov khoom siv hluav taws xob, tsis ua haujlwm ntawm oscillating circuit, overload ntawm lub hwj huam mov, thiab rectification. diodes nyob rau hauv lub siab zaus rectification lim Circuit Court. Kev tawg, lim capacitor leakage, thiab lwm yam. Tom qab ntsuas cov khoom sib txuas nrog lub tshuab multimeter thiab tsis suav nrog qhov kev puas tsuaj ntawm cov khoom siv hluav taws xob rectifier diode thiab luv luv Circuit Court ntawm lub load, yog tias cov zis yog xoom nyob rau lub sijhawm no, nws yog qhov tseeb tias kev tswj hwm. Circuit Court ntawm lub hwj chim mov yog faulty. Yog hais tias muaj ib feem ntawm qhov tso zis voltage, nws txhais tau hais tias lub pre-theem Circuit Court ua hauj lwm ib txwm, thiab qhov txhaum yog nyob rau hauv high-frequency rectification thiab filtering Circuit Court. Lub high-frequency lim Circuit Court yog tsim los ntawm ib tug rectifier diode thiab ib tug low-voltage lim capacitor los tso zis DC voltage. 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 tsis muaj zog xws li cov zis tsis ruaj khov. Cov khoom puas tuaj yeem raug kuaj xyuas los ntawm kev ntsuas qhov sib thooj nrog lub multimeter.
Tsis zoo zog load peev
Lub peev xwm thauj khoom tsis zoo ntawm cov khoom siv hluav taws xob yog qhov ua txhaum ntau, uas feem ntau tshwm sim hauv cov khoom siv hluav taws xob qub lossis cov khoom siv hluav taws xob 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 dissipation tsis ua raws sijhawm. Nws yuav tsum tsom mus xyuas seb lub Zener diode puas muaj cua sov, lub rectifier diode puas, thiab lub high-voltage lim capacitor puas.
