Switching power supply feem ntau tsis ua hauj lwm tsom xam
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. Raws li cov khoom siv hluav taws xob ua haujlwm nyob rau hauv high voltage, high tam sim no lub xeev, qhov hloov ntawm daim phiaj voltage, surge yuav ua rau ib tug instantaneous nce nyob rau hauv tam sim no nyob rau hauv lub hwj chim mov thiab ua rau lub fuse tshuab. Ua kom pom tseeb yuav tsum xyuas lub hwj chim input rectifier diode, high-voltage filtering electrolytic capacitors, inverter fais fab hloov raj, thiab lwm yam., xyuas cov khoom no tsis muaj kev puas tsuaj, qhib Circuit Court, puas, thiab lwm yam .. Yog hais tias lub fuse yog cua tshuab, koj yuav tsum xub saib Nyob rau hauv lub Circuit Court board Cheebtsam, saib cov tsos ntawm cov Cheebtsam tsis tau hlawv, tsis muaj electrolyte overflow, yog hais tias koj tsis pom qhov teeb meem saum toj no, ces siv ib tug multimeter los ntsuas lub switching tube nrog los yog tsis muaj luv-circuit breakdown. Kev saib xyuas tshwj xeeb yuav tsum tau them rau: Tsis txhob hnov qab tias thaum twg cov khoom puas lawm, hloov ncaj qha tom qab khau raj, nws yog qhov yuav tshwm sim vim tias lwm cov khoom siv hluav taws xob tseem tsis raug thiab yuav hloov cov khoom puas tsuaj, nco ntsoov xyuas tag nrho cov khoom siv hluav taws xob. high-voltage Cheebtsam ntawm lub Circuit Court saum toj no ** kuaj ntsuas nyob rau hauv thiaj li yuav txiav txim tag nrho cov txhaum ntawm lub tshuab fuse. Humidity sensor sojntsuam , , Stainless hlau rhaub PT100 sensor , , Cam khwb cia txhuas rhaub , Cua sov coil kua solenoid valve
Tsis muaj DC voltage tso zis los yog tsis ruaj tsis khov voltage tso zis
Yog tias lub fuse tsis zoo, tsis muaj DC qhov hluav taws xob tso tawm ntawm txhua theem hauv qab load. Qhov teeb meem no feem ntau yog tshwm sim los ntawm cov laj thawj hauv qab no: qhib Circuit Court thiab luv luv Circuit Court tshwm sim hauv cov khoom siv hluav taws xob, dhau-voltage thiab dhau-tam sim no tiv thaiv Circuit Court tsis ua haujlwm, pab cuam fais fab tsis ua hauj lwm, oscillation circuit tsis ua hauj lwm, fais fab mov yog overloaded, high- zaus rectifier lim Circuit Court rectifier diode yog punctured, to ntawm lim capacitors thiab hais txog. Nyob rau hauv lub multimeter los ntsuas qhov thib ob Cheebtsam, txiav tawm lub high-frequency rectifier diode breakdown, luv luv-circuit load, yog hais tias cov zis yog xoom nyob rau hauv lub sij hawm no, koj yuav tsum paub tseeb tias lub hwj chim mov tswj Circuit Court tsis ua hauj lwm. Yog hais tias muaj ib feem ntawm cov zis voltage qhia tau hais tias lub pem hauv ntej theem Circuit Court ua hauj lwm zoo, qhov txhaum yog nyob rau hauv lub high-frequency rectifier lim circuit. High-frequency lim Circuit Court yog tsim los ntawm rectifier diode thiab low-voltage filter capacitor DC voltage output, uas rectifier diode breakdown yuav ua rau lub Circuit Court tsis muaj hluav taws xob tawm, lim capacitor to yuav ua rau cov zis tsis ruaj khov thiab lwm yam txhaum. Nrog ib tug multimeter static ntsuas ntawm cov khoom sib thooj tuaj yeem kuaj xyuas ntawm cov khoom puas.
Tsis zoo load peev xwm ntawm lub hwj chim mov
Lub peev xwm tsis zoo ntawm cov khoom siv hluav taws xob yog qhov ua tsis tau zoo, feem ntau nyob rau lub sijhawm qub lossis ntev ua haujlwm ntawm cov khoom siv hluav taws xob, qhov laj thawj tseem ceeb yog kev laus ntawm cov khoom, lub raj hloov pauv tsis ruaj khov, tsis muaj cua sov raws sijhawm thiab lwm yam. Yuav tsum tsom mus xyuas seb qhov voltage regulator diode heat to, rectifier diode puas, high-voltage filter capacitor puas.
