Nws zoo nkaus li tias kev tsim cov roj teeb lub roj tsheb tsuas yog rau kev tshaj lij xwb. Qhov tseeb, koj tuaj yeem tsim qhov khoom siv no nrog koj tus kheej txhais tes, los ntawm txhais tau tias tsim kho, txawm hais tias qhov no yuav xav tau qee yam txuj ci kev paub. Txhawm rau ua qhov no, koj yuav xav tau cov khoom seem uas tej zaum yuav pom nyob hauv koj lub tsev, piv txwv, sab laug los ntawm lub khoos phis tawm qub.
Nws yog qhov tsim nyog
- • Lub zog hloov hluav taws xob TS-180-2, xov hlau txuas nrog ntu ntawm 2.5 mm2, plaub diodes D242A, ntsaws hluav taws xob, soldering hlau, solder, fuses 0, 5A thiab 10A;
- • cov teeb lub teeb hauv tsev nrog lub zog loj txog 200 W;
- • hluav taws xob semiconductor diode uas coj hluav taws xob hauv ib qho kev taw qhia nkaus xwb. Lub laptop laptop charger yuav siv tau xws li lub diode.
Cov Lus Qhia

Kev siv lub roj teeb hluav taws xob yooj yim tuaj yeem tsim los ntawm lub khoos phis tawm ntawm lub computer qub. Txij li thaum them lub roj teeb yuav tsum tau 10% ntawm tag nrho cov roj teeb muaj peev xwm, txhua lub zog muaj hluav taws xob uas muaj peev xwm ntau dua 150 volts tuaj yeem yog qhov muaj txiaj ntsig zoo ntawm kev siv. Yuav luag txhua cov khoom siv hluav taws xob muaj cov PWM tswj hwm raws li TL494 nti (lossis zoo ib yam li KA7500). Ua ntej tshaj plaws, koj yuav tsum tshem tawm cov xaim ntxiv (los ntawm qhov chaw -5V, -12V, + 5B, + 12B). Tom qab ntawd tshem tawm lub resistor R1 thiab hloov nws nrog trimmer resistor nrog tus nqi siab tshaj plaws ntawm 27 kOhm. Lub kaum rau davhlau ya nyob twg kuj tseem txiav tawm ntawm lub xov hlau tseem ceeb, kaum plaub thiab kaum tsib yog txiav ntawm qhov kev sib tshuam.

Txhawm rau cov txheej txheem yooj yim, nws yog qhov zoo dua los npaj lub zog tiv thaiv ua ntej. Nws kuj tuaj yeem tsim los ntawm txhais tes: txuas ib khub ntawm 5 qhov hluav taws xob tam sim no kev txiav txim siab resistors. Tag nrho cov hwj huam yuav yog 10 volts thiab qhov tsis kam yuav yog 0.1 ohm. Lub charger yuav tsum tau teeb tsa rau tib lub rooj tsavxwm. Ua li no, lub ntsuas phoo txuas nrog nws. Txhawm rau tshem tawm qhov tshwm sim ntawm qhov tsis tsim nyog txuas ntawm tus ncej thiab Circuit Court loj, nws yog qhov tseem ceeb kom tshem tawm ib feem ntawm cov ntawv luam. Qhov no yog qhov tseem ceeb vim tias, ua ntej, rooj plaub hlau ntawm lub zog txuas hluav taws xob yuav tsum tsis txhob nkag mus rau hauv galvanic txuas nrog lub roj teeb them Circuit Court, thiab, thib ob, lub cab kis tau raug tshem tawm.

Tam sim no peb yuav tsum los nrog pins 1, 14, 15 thiab 16. Ua ntej, lawv yuav tsum tau irradiated. Ua li no, cov hlau raug ntxuav ntawm rwb thaiv tsev thiab hlawv nrog hlau soldering. Qhov no yuav tshem tawm cov oxide zaj duab xis, tom qab ntawd cov hlau siv thov rau daim ntawm rosin, thiab tom qab ntawd nias dua nrog cov hlau soldering. Cov hlau yuav tsum tig daj-xim av. Tam sim no koj yuav tsum tau muab nws txuas rau ib daim ntawm solder thiab nias nws rau qhov thib peb, kawg lub sijhawm nrog hlau soldering. Cov xaim yuav tsum tig nyiaj. Tom qab qhov kawg ntawm tus txheej txheem no, nws tseem mus rau seem ntau ntawm cov xaim nyias daim hlau.

Idling yuav tsum tau teeb nrog qhov ntsuas qhov ntsuas nyob ntawm qhov chaw nruab nrab ntawm potentiometer R10. Lub tshuab hluav taws xob qhib hluav taws xob yuav teeb tsa tag nrho cov nqi ntawm 13.8 txog 14.2 volts. Clips raug ntsia ntawm qhov kawg ntawm cov terminals. Nws yog qhov zoo dua los ua cov kab insulating ntau cov xim txhawm rau txhawm rau txhawm rau txhawm rau hauv cov xov hlau. Qhov no tuaj yeem ua kev puas tsuaj ntawm lub cuab yeej. Liab feem ntau yog hais txog ntxiv thiab dub rau Rho tawm.

Yog tias cov cuab yeej tsuas yog siv los them lub roj teeb, koj tuaj yeem ua yam tsis muaj voltmeter thiab ammeter. Nws yuav txaus siv cov ntsuas ntsuas ntawm potentiometer R10 nrog tus nqi ntawm 5, 5-6, 5 amperes. Cov txheej txheem kev them nyiaj los ntawm cov cuab yeej siv no yuav tsum yooj yim, tsis siv neeg thiab tsis xav tau koj cov kev siv zog ntxiv. Cov charger no zoo tshem tawm qhov ua tau los ntawm overheating lossis overcharging lub roj teeb.

Lwm txoj hauv kev ntawm kev tsim cov roj teeb tsheb nrog koj tus kheej txhais tes yog raws li siv cov kev hloov kho ntawm kaum ob-volt adapter. Nws tsis tas yuav lub tsheb roj teeb hluav taws xob tiv thaiv. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub roj teeb ntawm lub roj teeb thiab qhov ntsuas hluav taws xob ntawm lub zog hluav taws xob yuav tsum sib npaug, tsis li lub charger yuav tsis muaj nuj nqi.

Ua ntej koj yuav tsum txiav thiab txiav qhov kawg ntawm tus xaim adapter mus rau 5 cm. Tom qab ntawd cov kab hluav taws xob sab nraud tau raug sib cais los ntawm 40 cm. Tam sim no koj yuav tsum muab tso rau ntawm daim tawv ntoo zaws ntawm txhua tus xov hlau. Nco ntsoov nqa cov yeeb yuj thaij xim kom tsis txhob thim rov qab qhov polarity. Nws yog ib qho tsim nyog yuav tsum sib txuas txhua lub davhlau ya nyob nrog cov roj teeb, ua raws li lub hauv paus ntsiab lus "los ntawm ntxiv rau ntxiv" thiab "los ntawm rho tawm mus rau rho tawm". Tam sim no nws tseem nyob tig rau lub adapter. Txoj kev no yog qhov yooj yim heev, tsuas yog qhov nyuaj yog xaiv qhov muaj hwj huam. Xws li lub roj teeb tuaj yeem ua kom sov dhau thaum them nyiaj, yog li nws tseem ceeb heev uas yuav saib xyuas nws thiab cuam tshuam ib ntus thaum muaj overheating.

Lub roj teeb lub roj teeb tuaj yeem tsim los ntawm lub teeb hloov kho dua li niaj zaus thiab diode. Xws li cov cuab yeej siv yuav yooj yim heev thiab yuav tsum muaj ob peb qho tseem ceeb thaum pib ua: lub teeb hluav taws xob, lub xov hluav taws xob me me, cov xov hluav taws xob nrog cov cim thiab ntsaws. Lub qhov muag teeb yuav tsum txog 200 វ៉ុល. Qhov siab zog nws lub zog, cov txheej txheem kev them nyiaj sai dua. Ib semiconductor diode yuav tsum tsuas ua hluav taws xob nyob rau hauv ib qho kev taw qhia xwb. Koj tuaj yeem nqa, piv txwv li, them nyiaj los ntawm lub laptop.

Lub teeb lub teeb yuav tsum tau taws ntawm ib nrab ntawm qhov sib tw, tab sis yog tias nws tsis pom txhua lub sijhawm, lub Circuit Court yuav tsum tau hloov kho. Nws yog tau hais tias lub teeb yuav tua thaum lub roj teeb lub roj teeb tau siab, tab sis qhov no tsis zoo li. Them nrog lub cuab yeej zoo li no yuav siv sijhawm li 10 teev. Tom qab ntawd nws yog qhov tsim nyog yuav tsum txiav tawm ntawm lub network, txwv tsis pub dhau overheating yog kev tsis pom kev, uas yuav txiav tawm lub roj teeb.

Yog tias qhov xwm txheej yog qhov tseem ceeb, thiab tsis muaj sijhawm rau kev tsim cov khoom siv hluav taws xob ntau dua, koj tuaj yeem them lub roj teeb uas siv cov diode muaj zog thiab lub rhaub siv tam sim no los ntawm lub ntsiab. Koj yuav tsum txuas rau lub network hauv cov txheej txheem hauv qab no: diode, tom qab ntawd rhaub, tom qab ntawv roj teeb. Txoj kev no tsis muaj txiaj ntsig, vim nws siv ntau qhov hluav taws xob, thiab qhov ua tau zoo yog tsuas yog 1%. Yog li no, lub thawv hluav taws xob no yog qhov tsis tseem ceeb, tab sis kuj yog cov yooj yim tshaj plaws los tsim khoom.
