1) Kodi pali kusiyana kotani pakati pa DC ndi AC contactors kuwonjezera pa koyilo?
2) Vuto ndi chiyani ngati mphamvu ya AC ndi voteji zikulumikiza koyilo pamagetsi ovotera a koyilo pomwe magetsi ndi magetsi akufanana?
Yankho ku funso 1:
Coil wa DC contactor ndi wamtali ndi woonda, pamene AC contactor koyilo ndi lalifupi ndi fat.Choncho, kukana koyilo ya koyilo DC ndi yaikulu, ndipo kukana koyilo ya AC koyilo ndi kochepa.
Ma contactor a DC ndi ma relay a DC nthawi zambiri amagwiritsa ntchito koyilo yapawiri, pomwe koyilo yapano imagwiritsidwa ntchito poyamwa ndipo koyilo yamagetsi imagwiritsidwa ntchito poyamwa.
The AC contactor ndi koyilo limodzi.
Pakatikati pachitsulo ndi zida za cholumikizira cha DC ndi chitsulo chonse chofewa chamagetsi, ndipo cholumikizira cha AC ndi stack yachitsulo ya silicon kuti muchepetse kutayika kwa AC.
The flux mu AC contactor pachimake ndi alternating ndipo ali pa zero.Panthawi imeneyi, armature adzabwerera mmbuyo pansi anachita mphamvu, ndiyeno kugwira pambuyo ziro, kotero AC kukhudzana pachimake ayenera okonzeka ndi lalifupi dera kuzungulira kuthetsa. maginito kudzera pa zero oscillation.
zolumikizira ndi ma relay ma coil zimatulutsa mphamvu zambiri zikatulutsidwa, zolumikizira za DC ndi ma relay nthawi zambiri amachotsedwa ndi ma diode am'mbuyo, ndi zolumikizira za AC ndi ma relay okhala ndi ma RC mabwalo.
DC contactor kukhudzana arc zovuta, kuti zigwirizane ndi maginito kuwomba arc.AC contactor ndi zosavuta arc, ntchito C woboola pakati dongosolo ndi arc chipata.
Yankho ku funso 2:
The DC contactor koyilo panopa ndi yaing'ono pamene DC voteji ndi AC ogwira voteji.Choncho, pamene magetsi awiri anazimitsa, ndi DC contactor mwina si chinkhoswe, ndi AC contactor amayaka yomweyo.
Komanso, DC contactor yomweyo amayaka pambuyo kuthandiza kupitiriza diode pa AC dera.
