Automotive roj teeb - lub roj teeb hluav taws xob rau tsheb. Lub roj teeb muaj zog rau ntau lub tsheb, xws li lub cav tswj lub cav, tus ntsuas roj, tus pib, cov khoom siv hluav taws xob. Ntau yam roj teeb tau siv los them lub roj teeb. Yog tias koj paub ua haujlwm nrog hlau soldering thiab nkag siab txog kev tsim qauv ntawm hluav taws xob hluav taws xob kos duab, koj tuaj yeem sib sau tus nqi yooj yim hauv ib hmos.
Nws yog qhov tsim nyog
- -tus neeg txhais lus los ntawm cov raj TV - 1;
- - diodes KD 2010 - 4;
- - 600 ohm resistor, 5 watts - 1;
- -tau rau 15 A, 250 V - 1;
- - LED rau 12-15 V - 1;
- - lub ntsiab fuse rau 1 A - 1;
- - network ntsaws - 1.
Cov Lus Qhia
Kauj ruam 1
Yuav lub hwj chim uas hloov pauv kom muaj zog ntawm lub tsev xa hluav taws xob ntawm lub raj roj teeb dub thiab dawb hauv TV hauv xov tooj cua. Yog tias koj muaj lub TV nyob ib puag ncig hauv tsev, rhuav lub transformer los ntawm nws. Tso cov hluav taws xob hloov mus ntxiv los ntawm txhawm rau windings los ntawm cov tub ntxhais. Txheeb xyuas qhov chaw ntawm qhov hloov hluav taws xob loj yog nyob ntawm qhov hloov pauv. Txhawm rau ua qhov no, tshawb xyuas qhov tsis kam ntawm txhua qhov windings nrog multimeter. Lub ntsiab winding yuav muaj qhov zoo tshaj plaws ohmic tsis kam. Tshem tag nrho cov kab cua ntawm lub tshuab hloov hluav taws xob thiab tawm tsuas yog cov mains. Ntawm cov xov uas koj tshem tawm yuav yog cov tooj liab ntev nrog txoj kab uas hla 2 millimeters. Cua lub caij hloov ceev thib ob ntawm lub tshuab hloov pauv nrog nws tus nqi ntawm 55 lem nrog tus kais los ntawm 10 thib.

Yuav cov khoom siv hluav taws xob zoo (semiconductor diodes), piv txwv li KD 2010, los ntawm lub khw xov tooj cua. Lawv yuav tsum ua tus choj txuas rau - qhov txuas ntawm lub network. Lub yees duab ntawm sab laug qhia cov hom pom zoo ntawm tus choj diode nce. Yog hais tias cov diodes ua kub dhau heev thaum lub sijhawm ua haujlwm, nruab lawv txhua tus ntawm lub ntsuas kub cais me me. Nyob rau hauv tib qho chaw, yuav lub qhov hluav taws xob loj, ib qho 1 amp mains fuse, ib qho 600 ohm 5 watt resistor, ib yam li LED tsim rau qhov hluav taws xob tsawg kawg 12 volts.

Pib sib sau lub charger ua ntej raws li daim duab schematic daim duab uas pom nyob hauv daim duab ntawm sab laug. Txuas lub mains fuse FU1 mus rau lub ntsiab ntsaws. Solder qhov tshwm sim luv luv-thaiv kev tiv thaiv mus rau thawj winding ntawm Tr1 main transformer. Ntxiv mus, raws li daim duab saum toj no, sib sau ua ke hauv lub vev xaib rectifier - lub diode choj ntawm lub rooj tsav xwm nyias. Txuas nws mus rau theem nrab winding ntawm transformer raws li daim duab schematic. Los ntawm tus tes hloov qhov hluav taws xob txuas, txuas lub diode choj txuas rau 10 volt thiab 15 volt transformer outputs. Muag cov saw uas muaj cov resistor R1 thiab LED La1 rau qhov tso tawm rectifier. Lub resistor txwv qhov tam sim no ntws los ntawm LED. Lub LED yog siv los qhia txog kev ua haujlwm ntawm lub cuab yeej. Yog tias LED tsis pom kev, hloov nws cov ua haujlwm.

Los ntawm hloov qhov chaw ntawm lub pob hluav taws xob hloov, koj yuav tau txais hluav taws xob sib txawv thiab qhov sib txawv them tam sim no ntawm cov zis ntawm tus them. Qhov ntsuas hluav taws xob yog 15 volts, raws li lub phiaj xwm - rau kev ceev ceev ntawm lub roj teeb (tsis pub dhau 6 teev). Qhov ntsuas hluav taws xob yog 10 volts, raws li daim duab - rau kom qeeb, tab sis zoo dua roj teeb kev them nqi (tsis pub dhau 10 teev). Tom qab sib dhos thiab tshawb xyuas lub sijhawm ua haujlwm ntawm lub cuab yeej, saib rau lub tsev uas sib phim rau qhov loj me ntawm cov qauv koj tau sib sau ua ke.
