- Kev ceev faj txog kev nyab xeeb rau kev ua haujlwm hluav taws xob.
Yog tias tsim nyog los kho cov kab hluav taws xob, tus kws hluav taws xob yuav tsum paub thiab nthuav dav nws cov kab hluav taws xob, thiab tuaj yeem kuaj xyuas qhov ua tsis tiav.
Kev txawj
Kev cob qhia rauhluav taws xob instills cov txheej txheem ua haujlwm tsim nyog. Ib tus kws tshaj lij kawm nyeem cov kab kos duab thiab cov kab kos duab, suav cov kab lus hla ntawm cov xov hlau, ua haujlwm nrog cov cuab yeej ntsuas, nws tus kheej sib sau ua ke cov hluav taws xob yooj yim, thiab solder lossis twist lub rooj sib txuas ntawm kev sib txuas.
Main tool
Cov khoom tsim nyog rau kev ua haujlwm ntawm tus kws kho hluav taws xob tau muab faib ua plaub pawg:
- hand tool;
- lub cuab tam;
- ntsuas ntsuas;
Yuav khoom thiab khoom siv.
Cov cuab yeej siv tes yog tus kheej rau txhua tus kws kho hluav taws xob. Tab sis muaj lub hauv paus tsim nyog. Tom qab ua tiav kev cob qhia ua tus kws tshaj lij hluav taws xob, tus kws tshaj lij cov tub ntxhais hluas yuav paub txog kev ua haujlwm nrog cov pliers (nippers), mounting lossis riam riam, ib txheej ntawm cov ntsia hlau thiab cov ciaj ntswj, rauj, chisel, siv daim kab xev ntsuas, stripper thiab hluav taws xob soldering hlau.
Yog tias kev tsim hluav taws xob ua haujlwm yuav tsum muaj kev cuam tshuam loj dua, ces koj yuav xav tau lub puncher nrog lub adapter cartridge thiab ib txheej ntawm nozzles, grinder rau txiav steel fab rau lub hauv paus system los yog nteg ib tug strobe nyob rau hauv cables. Koj tseem yuav xav tau lub laum hluav taws xob, uas, yog tias tsim nyog, tuaj yeem ua haujlwm ua tus ntsia hlau ntsia hlau.
Raws li hauv qab no los ntawm chav kawm "Electricians for Beginners", ntsuas cov cuab yeej niaj hnub no ua tau ntau yam haujlwm thiab lawv tsim nyog hauv kev ua haujlwm. Ib qho ntawm cov tseem ceeb tshaj plaws yog kev sojntsuam rau lub xub ntiag ntawm ib theem hauv cov hluav taws xob network. Zoo li lub taub hau, tab sis lub cev tsis ruaj khov,vim cov cuab yeej muaj lub hom phiaj sib txawv. Xav paub ntau ntxiv tuaj yeem nyeem los ntawm universal multimeter. Ntxiv nrog rau kev ntsuas yooj yim, nws muaj peev xwm txheeb xyuas qhov tseeb ntawm cov cuab yeej nruab lossis cov kev sib txuas. Tam sim no clamps tso cai rau koj mus txuas yam tsis cuam tshuam lub network thiab ntsuas.
Cov khoom siv pabcuam tsis suav nrog hauv cov npe yuav tsum tau ua, tab sis pab txhawb kev ua haujlwm ntawm tus kws tshaj lij. Nws tuaj yeem yog tus ntaiv, tus nqa khoom, lub teeb pom kev ywj pheej, cov cim, cov xaum siv, qib, calipers, thiab lwm yam.
