Ntau tus neeg tsav tsheb muaj qhov xav tau los txuas cov khoom siv hluav taws xob ntau rau hauv lub network. Ntawm lawv yog lub xov tooj txawb them nyiaj, lub tshuab nqus tsev, TV, laptop. Qhov xwm txheej tsis yooj yim yog tias cov khoom siv sib txuas tau raug tsim los txhawb los ntawm on-board network. Thiab yog tias qhov voltage ntawm cov cuab yeej tsis tsim rau qhov voltage uas muaj nyob hauv lub tsheb network? Xws li lub cuab yeej yog lub laptop.
Cov Lus Qhia
Kauj ruam 1
Yuav cov cuab yeej tshwj xeeb - pib hloov kho rau lub laptop, uas yuav tsum muaj lub tshuab luam yeeb sib dua ntais. Thov nco ntsoov tias lub teeb hluav taws xob ntawm lub laptop fais fab mov thiab lub cuab yeej siv yuav tsum zoo ib yam. Kev khiav hauj lwm voltage ntawm koj lub computer yog li 15 txog 24 volts.
Kauj ruam 2
Nco ntsoov tias lub hwj huam hluav taws xob thiab kev hloov kho yuav tsum ib txwm muaj tib lub voltage ua hauj lwm, qhov tsis sib xws ntawm tsuas yog ib lub volt raug tso cai. Cov cuab yeej siv plugs muaj cov qauv tsim thiab txuas polarity. Lub cim polarity ntawm qhov pib hloov kho thiab lub laptop yuav tsum sib phim.
Kauj ruam 3
Muaj cov hloov hluav taws xob ntau uas muaj qhov hloov hluav taws xob tawm. Ntawm no koj tuaj yeem tsis quav ntsej qhov tsis haum ntawm cov tsis, qhov no yog ua tiav los ntawm kev teeb tsa qhov xav tau voltage nrog lub hloov. Cov kev hloov kho no muaj nyob rau ob hom: nrog cov zis tam sim no ntawm 4.7 amperes rau lub laptop nrog kab pheeb ces kaum ntawm 17 nti thiab nrog tam sim no ntawm 3.7 amperes rau kab pheeb ces kaum ntawm 15 nti.
Kauj ruam 4
Yuav ib lub inverter yog tias koj xav ua lub chaw txawb nruab nrab ntawm koj lub tsheb, kev txuas ntawd kuj tseem muaj lub tshuab luam ntawv thiab lub scanner. Cov hloov hluav taws xob hloov lub tshuab cov hluav taws xob loj rau 220 volts, uas yog cov qauv. Lawv txawv nyob rau hauv lub hwj chim, thiab cov khoom siv sib txuas ntau dua, cov hwj huam loj dua ntawm inverter.
