Nkag siab txog kev saib xyuas lub xov tooj ntawm tes thiab kev daws teeb meem

Cov hluav taws xob zoo li qub thaum ntxuav. Ntxuav lub charger thiab chaw nres nkoj tsis tu ncua. Thaum ntxuav, siv ib daim ntaub ntub dej los yog daim ntaub antistatic. Tsis txhob siv daim ntaub qhuav (tus nqi zoo li qub)!

Waterproof thiab moistureproof. Raws li cov khoom siv hluav taws xob, dej tsis pom kev lossis raug huab cua ntub rau lub sijhawm ntev yam tsis siv yuav ua rau ntau qib ntawm corrosion lossis oxidation ntawm nws cov khoom siv hluav taws xob sab hauv.

Poob thiab poob siab. Lub xov tooj ntawm tes charger yog qhov tsis yooj yim, thiab cov khoom sab hauv tsis tuaj yeem tiv taus qhov sib tw. Tshwj xeeb tshaj yog, tiv thaiv kev sib tsoo thaum siv. Tsis txhob muab pov, ntaus lossis co lub charger. Rough kho ntawm lub charger yuav rhuav tshem lub sab hauv Circuit Court board

Txias thiab kub-pov thawj. Tsis txhob muab lub charger tso rau hauv qhov chaw uas qhov kub thiab txias heev. Qhov kub thiab txias tuaj yeem ua rau lub neej ntawm cov khoom siv hluav taws xob luv luv, ua kom puas lub charger, thiab deform lossis yaj qee qhov yas. Tsis txhob khaws lub charger rau hauv qhov chaw txias heev. Thaum lub charger ua hauj lwm nyob rau hauv ib qho chaw txias, thaum lub sab hauv kub nce, noo noo yuav tsim nyob rau hauv lub charger thiab puas lub Circuit Court board.

Cov tshuaj muaj zog. Tsis txhob siv cov tshuaj muaj zog, tshuaj ntxuav tes lossis tshuaj ntxuav tes kom huv si. Tshem tawm cov tsos ntawm lub charger stains tuaj yeem siv cov cawv me me los so nrog me me ntawm cawv.

1. Tom qab lub roj teeb thiab lub hwj huam sib txuas, qhov taw qhia lub hwj chim thiab ntsuas ntsuas lub teeb, thiab lub teeb them thiab qhov taw qhia tag nrho tsis nyob, tsis muaj hluav taws xob tawm, thiab lub roj teeb tsis tuaj yeem them.

Kev tshuaj xyuas thiab kev saib xyuas: Hom kev ua tsis tiav no feem ntau tshwm sim los ntawm lub charger hloov oscillation circuit tsis ua haujlwm. Nyob rau hauv txoj kev kho tiag tiag, nws tau pom tias lub raj hloov VT2 thiab cov resistor R6 puas feem ntau. Raws li ib txwm muaj, qhov kev khiav hauj lwm voltage ntawm lub charger Circuit Court ntawm lub roj teeb E yog qhov tsawg, thiab qhov tshwm sim ntawm kev puas tsuaj ntawm nws cov khoom tsis loj, uas yog, qhov tshwm sim ntawm kev puas tsuaj ntawm Circuit Court tom qab qhov thib ob ntawm kev hloov pauv hloov T1 yog. tsis loj heev.

2. Tom qab lub roj teeb thiab lub hwj chim sib txuas, cov xwm txheej qhia tau hais tias ib txwm muaj, tab sis lawv tsis tau them lossis them rau lub sijhawm ntev.

Kev tshuaj xyuas thiab kev saib xyuas: Hom kev ua txhaum no yog tshwm sim los ntawm kev puas tsuaj rau transistor VT3 (8550). Tom qab hloov nws nrog cov yeeb nkab ib txwm, qhov txhaum tuaj yeem raug tshem tawm. Yog hais tias lub triode VT3 yog ib txwm, ces siv ib lub 'meter' los ntsuas qhov voltage hla lub capacitor C3 (100μF / 16V), uas yog hais txog 8.5V DC. Yog tias qhov hluav taws xob zoo li qub, kos cov resistor R7 lossis IC1. Qhov ib txwm tsis muaj ntawm txhua tus pin ntawm IC1 tau qhia hauv cov lus txuas. Yog tias qhov hluav taws xob tsawg, ces ntsuas qhov hluav taws xob theem nrab ntawm qhov hloov pauv hloov T1, feem ntau txog 5.5V AC. Yog tias qhov hluav taws xob zoo li qub, lub capacitor C3 lossis lub rectifier diode VD3 puas lawm; Yog tias qhov hluav taws xob tsawg, lub transformer T1 thiab nws cov khoom ua ntej yuav tsum tau kuaj xyuas.
