Cov khoom siv hluav taws xob feem ntau xav tau 12 volt DC fais fab mov. Ua-nws-koj tus kheej hloov cov khoom siv hluav taws xob tau sib sau ua ke ntawm lub hauv paus ntawm microcircuit nrog rau qhov tsim nyog tsis. Nws kev xaiv yog ua raws li cov lus xov tooj cua. Cov kauj ruam-down transformer yog qhov txhab ntawm lub nplhaib ferrite, cov khoom qib yog M200MN.
YTransformer manufacturing
Tus thawj winding muaj ib tug insulated hlau MGTF 0, 7, lub thib ob ntawm cov hlau PEV-1, folded nyob rau hauv ib nrab. Nruab nrab ntawm lawv yuav tsum muaj ib txheej insulating, uas yog ua los ntawm fluoroplastic daim kab xev. Qhov thib ob winding nyob rau hauv nruab nrab ib feem muaj ib tug ntxiv ceg rau powering lub microcircuit tswj. Sab nraud, cov xov hlau raug kaw nrog ob txheej ntawm PTFE daim kab xev.
Ua-nws-koj tus kheej hloov cov khoom siv hluav taws xob tau teeb tsa rau ntawm lub rooj tsav xwm luam tawm ua los ntawm ib sab fiberglass. Kev siv tshuab ntau lawmcov khoom zoo li no tau piav qhia meej hauv cov ntaub ntawv uas cuam tshuam thiab dhau ntawm cov kab lus. Kev kos duab ntawm cov khoom nqa tam sim no rau lub rooj tsav xwm luam tawm tau tsim los ntawm lub hauv paus ntawm daim duab kos duab ntawm lub cuab yeej. Cov transistors yuav tsum tau heatsinks, uas yog tsim los ntawm txhuas phaj.
xav tau xov tooj cua
Raws li kev tawm tswv yim choke, nws yog qhov tsim nyog los siv cov chokes npaj txhij, cov no feem ntau yog ntsia rau hauv cov khoom siv hluav taws xob rau cov khoom siv lossis cov khoos phis tawj. Lub capacitor yog xam raws li qhov piv ntawm capacitance thiab lub zog ib mus rau ib qho. Lub rectifier yog tsim los ntawm tus choj diode nrog kev ua haujlwm tsawg zaus. Xws li cov cuab yeej muaj peev xwm muab qhov tam sim no txog li 3 amperes ntawm cov zis.
Hloov cov khoom siv hluav taws xob siv hauv xov tooj cua hluav taws xob, hluav taws xob hluav taws xob uas tau ua haujlwm thiab sim tau ntev, muaj cov hloov pauv hloov pauv. Kev xaiv ntawm triodes yog ua raws li cov kev txwv tsis pub, IRF 840 lossis VT 1 thiab VT3 series tau ua pov thawj lawv tus kheej zoo. Txhawm rau kom ntseeg tau tias qhov ntsuas kub xav tau, transistors yuav tsum muaj lub tshuab cua txias kom tshem tawm cov cua sov ntau dhau.
Ua-nws-koj tus kheej hloov cov khoom siv hluav taws xob tau sib sau ua ke nrog cov khoom siv hluav taws xob hauv Circuit Court, sawv cev los ntawm chokes raws li cov ferrite cylinders txog 40 hli ntev nrog txoj kab uas hla ntawm 3 hli. Tight winding yog tsim los ntawm tib cov hlau raws li qhov thib ob winding ntawm lub transformer. Nws muaj peev xwm siv lwm txoj hauv kev kom ruaj khov rau pawg tso zis, tab sis cov txheej txheem pov thawj tau ntseeg tau. Nrhiav lwm txoj kev daws teeb meem hauv qhov no yuav yog qhov nkim sijhawm.
Sib dhos thiab teeb tsa
Qhov zoo tshaj plaws ua-nws-koj tus kheej lub zog hluav taws xob yog soldered ntawm lub rooj tsavxwm npaj. Thaum ua tiav kev teeb tsa, nws yog ib qho tsim nyog los xyuas kom meej lub teeb pom kev zoo ntawm qhov chaw ua haujlwm thiab qhov cua. Tom qab soldering, nws raug nquahu kom kuaj xyuas qhov kev ntseeg siab ntawm kev teeb tsa ntawm cov khoom siv hauv xov tooj cua thiab kev sib cuag ntawm lawv thiab cov lem tam sim no. Solder residues raug tshem tawm ntawm sab hauv, uas tuaj yeem ua rau luv luv.
Hloov cov khoom siv hluav taws xob, sib sau ua ke thiab npaj rau kev tshaj tawm nrog koj tus kheej txhais tes, raug pom zoo kom thauj khoom nrog lub ntsuas hluav taws xob tam sim no thaum kuaj. Hauv lub peev xwm no, 60 W incandescent teeb tuaj yeem siv tau, nws qhov kev suav nrog lub sijhawm luv luv yuav ua qhov qhia txog kev sib dhos kom raug.
