(1) Thaum muaj hluav taws xob hluav taws xob, 'saib, hnov ​​tsw, nug, ntsuas'

Saib: Qhib lub plhaub ntawm lub tshuab hluav taws xob, xyuas seb lub fuse puas tau tawg, thiab tom qab ntawd saib xyuas qhov xwm txheej sab hauv ntawm lub hwj huam mov.Yog tias muaj cov chaw hlawv lossis cov khoom tawg ntawm PCB pawg thawj coj saib ntawm cov khoom siv hluav taws xob, qhov tseem ceeb yuav tsum tau saib xyuas cov khoom thiab cov khoom siv hluav taws xob cuam tshuam ntawm no.

Hniav: Yog tias muaj ntxhiab tsw ntxhiab hauv lub hwj chim thiab xyuas seb puas muaj cov khoom siv hluav taws kub.

Q: Kuv puas tuaj yeem nug txog cov txheej txheem ntawm cov khoom siv hluav taws xob puas tsuaj thiab seb puas muaj kev ua haujlwm tsis raug cai tau ua tiav ntawm lub tshuab hluav taws xob.

Ntsuas: Ua ntej fais fab tuag, siv lub multimeter los ntsuas qhov voltage ntawm ob qho kawg ntawm high-voltage capacitor.Yog hais tias qhov txhaum yog tshwm sim los ntawm lub hwj chim tsis ua hauj lwm ntawm lub LED zaub screen los yog qhib Circuit Court ntawm lub hloov raj, feem ntau, qhov voltage ntawm ob qho tag nrho ntawm high-voltage filtering capacitor tsis tau tawm, uas yog tshaj 300 volts.Ceev faj.Siv lub multimeter los ntsuas qhov kev tiv thaiv rau pem hauv ntej thiab thim rov qab ntawm ob qho kawg ntawm AC fais fab kab thiab qhov kev them nqi ntawm lub capacitor.Tus nqi kuj yuav tsum tsis txhob qis dhau, txwv tsis pub yuav muaj qhov luv luv hauv cov khoom siv hluav taws xob.Capacitors yuav tsum tau them thiab tso tawm.Tshem tawm cov load thiab ntsuas qhov av tiv thaiv ntawm txhua pab pawg ntawm cov zis terminals.Feem ntau, lub meter koob yuav tsum muaj capacitor them thiab tso tawm oscillation, thiab qhov kawg qhia yuav tsum yog tus nqi tsis kam ntawm kev tawm tsam ntawm lub voj voog.

(2) Lub zog ntawm kev tshawb nrhiav

Tom qab siv hluav taws xob, saib seb cov khoom siv hluav taws xob puas tau hlawv fuses thiab cov khoom siv ib leeg tawm pa taws.Yog tias muaj, txiav tawm cov khoom siv hluav taws xob raws sijhawm rau kev saib xyuas.

Ntsuas seb puas muaj 300V tso zis ntawm ob qho kawg ntawm lub siab-voltage lim capacitor.Yog tias tsis yog, tsom mus rau kev kuaj xyuas lub rectifier diode, lim capacitor, thiab lwm yam.

Ntsuas seb lub coil thib ob ntawm high-frequency transformer muaj cov zis.Yog tias tsis muaj qhov tso tawm, tsom mus rau kev tshuaj xyuas seb lub raj hloov pauv puas puas, txawm tias nws vibrating, thiab seb qhov kev tiv thaiv Circuit Court puas ua haujlwm.Yog tias muaj, tsom mus rau kev kuaj xyuas lub rectifier diode, lim capacitor, peb-txoj kev regulator raj, thiab lwm yam ntawm txhua qhov tso zis.

Yog hais tias lub hwj huam mov pib thiab nres tam sim ntawd, nws yog nyob rau hauv lub xeev tiv thaiv.Qhov voltage ntawm PWM nti tiv thaiv tus pin tuaj yeem ntsuas ncaj qha.Yog hais tias qhov hluav taws xob ntau tshaj li tus nqi teev, nws qhia tau hais tias lub hwj chim mov yog nyob rau hauv ib tug tiv thaiv lub xeev, thiab vim li cas rau kev tiv thaiv yuav tsum tau ua tib zoo xyuas.
