(1) Uma kwenzeka kunqamuka ugesi, 'bheka, nuka, buza, kala'

Bheka: Vula igobolondo lokunikezwa kwamandla, hlola ukuthi i-fuse ishaywa yini, bese ubheka isimo sangaphakathi sokunikezwa kwamandla.Uma kunezindawo ezishile noma izingxenye eziphukile ebhodini le-PCB lokuphakelwa kukagesi, ukugxila kufanele kube ekuhloleni izingxenye nezingxenye zesekethe ezihlobene lapha.

Ukuhogela: Hola uma kunephunga elivuthayo ngaphakathi kugesi futhi uhlole ukuthi azikho yini izingxenye ezishile.

Umbuzo: Ngicela ukubuza mayelana nenqubo yokumosheka kokuphakelwa kukagesi nokuthi ngabe kukhona yini imisebenzi engekho emthethweni eke yenziwa ekuhlinzekweni kukagesi.

Kala: Ngaphambi kokukhanyisa, sebenzisa i-multimeter ukukala i-voltage kuzo zombili iziphetho ze-high-voltage capacitor.Uma iphutha libangelwa ukwehluleka kwamandla kwesikrini sokubonisa i-LED noma isifunda esivulekile seshubhu yokushintsha, ezimweni eziningi, i-voltage emikhawulweni yomibili ye-high-voltage filtering capacitor ayizange ikhishwe, engaphezu kuka-300 volts.Qaphela.Sebenzisa i-multimeter ukukala ukumelana nokuya phambili nokuhlehla kuzo zombili iziphetho zolayini wamandla we-AC kanye nesimo sokushaja se-capacitor.Inani lokumelana akufanele libe liphansi kakhulu, ngaphandle kwalokho kungase kube nesifunda esifushane ngaphakathi kokunikezwa kwamandla.Ama-Capacitor kufanele akwazi ukushaja futhi akhiphe.Nqamula umthwalo bese ukala ukumelana nomhlabathi kweqembu ngalinye lamatheminali okukhiphayo.Ngokuvamile, inaliti yemitha kufanele ibe nokushaja kwe-capacitor nokukhipha i-oscillation, futhi isibonakaliso sokugcina kufanele sibe yinani lokumelana lokumelana nokukhishwa kwesifunda.

(2) Amandla okuthola

Ngemva kokukhanyisa, bheka ukuthi ugesi unawo yini ama-fuse ashile futhi izingxenye ngazinye zikhipha intuthu.Uma kunjalo, nqamula ugesi ngesikhathi ukuze ulungiswe.

Linganisa ukuthi ingabe kukhona okukhiphayo okungu-300V kuzo zombili iziphetho ze-high-voltage filter capacitor.Uma kungenjalo, gxila ekuhloleni i-rectifier diode, i-filter capacitor, njll.

Linganisa ukuthi ikhoyili yesibili ye-high-frequency transformer inomphumela yini.Uma kungekho okukhiphayo, gxila ekuhloleni ukuthi ishubhu yokushintsha yonakele yini, iyadlidliza, nokuthi isifunda sokuvikela siyasebenza yini.Uma likhona, gxila ekuhloleni i-diode yokulungisa kabusha, i-filter capacitor, ishubhu yesilawuli sezindlela ezintathu, njll. ohlangothini ngalunye lokuphumayo.

Uma ukunikezwa kwamandla kuqala futhi kuma ngokushesha, kusesimweni esivikelekile.I-voltage yephinikhodi yokufaka yokuvikela i-chip ye-PWM ingalinganiswa ngokuqondile.Uma i-voltage idlula inani elishiwo, libonisa ukuthi ukunikezwa kwamandla kusesimweni esivikelwe, futhi isizathu sokuvikela kufanele sihlolwe ngokucophelela.
