Ekusetyenzisweni kwemihla ngemihla, ngenxa yendawo entsonkothileyo yokusetyenziswa kunye nomonakalo wecandelo, kusenokubakho kungabikho mveliso emva kokuba umbane oqalayo ukutshintshela ubushushu obuphantsi kakhulu uvuliwe, nto leyo eya kwenza ukuba isekethe elandelayo ingakwazi ukusebenza ngokuqhelekileyo. Ngoko ke, zeziphi izizathu eziqhelekileyo zokuqalisa ukutshintshela umbane kubushushu obuphantsi kakhulu?
1. Ukubetha kombane, ukunyuka okanye ukunyuka kwe-voltage xa kufakwa
Jonga ukuba i-fuse, i-rectifier bridge, i-plug-in resistor kunye nezinye izixhobo ezikwi-input front end yemveliso zonakele na, kwaye uhlalutye i-radio waveform ngokusebenzisa uvavanyo oluhlukileyo. Kucetyiswa ukuba isetyenziswe kwindawo ehlangabezana neemeko ze-EMS kwincwadi yemiyalelo yobugcisa. Ukuba kufuneka isetyenziswe kwindawo embi, isihluzi se-EMC kunye nesixhobo sokulwa nokunyuka kwamanzi kufuneka kongezwe kwi-front end yemveliso.
2. I-voltage yokufaka idlula inkcazo yemveliso yombane
Jonga ukuba i-fuse, i-plug-in resistor, i-capacitor enkulu kunye nezinye izixhobo ezikwisiphelo sokufaka imveliso zikwimeko entle na, kwaye uvavanye i-input voltage waveform ukuze ugwebe. Kucetyiswa ukuba ulungise i-input voltage, usebenzise umbane one-voltage efanelekileyo njenge-input, okanye uwutshintshe ngombane ophezulu wokufaka.
3. Izinto zangaphandle ezifana namaconsi amanzi okanye i-tin slag zinamathela kwimveliso, nto leyo ebangela ukuba kubekho i-internal short circuit.
Jonga ukuba ukufuma okungqongileyo kungaphakathi koluhlu oluchaziweyo. Okwesibini, qhaqha imveliso uze ujonge ukuba kukho izinto ezahlukeneyo kumphezulu wepatch kwaye nokuba umphezulu ongaphantsi ucocekile na. Kucetyiswa ukuqinisekisa ukuba indawo yovavanyo (yokusetyenziswa) icocekile, ubushushu kunye nokufuma kungaphakathi koluhlu oluchaziweyo, kwaye imveliso igqunywe ngepeyinti yokuqinisekisa ezintathu xa kuyimfuneko.
4. Umgca wokufaka wombane wokuqalisa oshushu kakhulu ucinyiwe okanye i-port yomgca wokudibanisa ayihambelani kakuhle.
Ukusombulula iingxaki: vavanya ukuba ingaba i-voltage yokufaka iqhelekile na ukusuka kwisiphelo sokufaka esisezantsi kwemveliso. Kucetyiswa ukuba kutshintshwe umgca wokudibanisa ongasebenziyo, kwaye ukuqhekeka kwesango lomgca wokudibanisa kufuneka kuqiniswe ukuze kuthintelwe ukudibana okubi.
Xa yonke into ilungile kwaye iqalisiwe ngokusesikweni, akukho mveliso okanye iingxaki kunye nokuxhuma okufunyenweyo. Isenokubangelwa kukuphazamiseka kwendalo yangaphandle okanye umonakalo kwizinto zangaphandle, njengomthwalo ogqithisileyo wokukhupha okanye umthwalo we-short circuit / capacitive odlula ixabiso lenkcazo, okubangela ukugqithisa ngokukhawuleza ngexesha lokuqalisa.
Okwangoku, sicebisa ukuba umthengi atshintshe imo yedrive yomthwalo we-back-end kwaye angasebenzisi i-direct drive yemveliso yombane.
