Makhalidwe atatu akuluakulu a AC contactor

Zolumikizira za ACndi zinthu zofunika kwambiri m'makina amagetsi, makamaka powongolera kuyambika ndi kuyimitsa kwa ma mota ndi zida zina. Ma contactor awa ali ndi makhalidwe angapo ofunikira omwe ndi ofunikira kuti dera liziyenda bwino. Zinthu zitatu zazikulu zomwe zimapangitsa kuti contactor ya AC igwire ntchito ndi monga coil ya contactor ya AC, main contacts ndi ma contact othandizira. Chikhalidwe chilichonse chimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti makina amagetsi akugwira ntchito bwino.

Choyamba, coil ya contactor ya AC ndiye chinthu chofunikira chomwe chimasiyanitsa ma contactor a AC ndiMa contactor a DCMa coil awa ali ndi zilembo za A1 ndi A2 ndipo makamaka ndi omwe amapanga mphamvu ya maginito yofunikira pakugwira ntchito kwa contactor. Kawirikawiri, ma coil a AC amagwiritsidwa ntchito m'njira zambiri, amatha kusintha mphamvu zamagetsi kukhala mphamvu yamakina, zomwe zimathandiza contactor kutseka ndikumaliza dera. Izi zimathandiza contactor ya AC kuwongolera bwino kayendedwe ka magetsi ndikuthandizira kuyambika ndi kuyimitsa kwa zida zosiyanasiyana zamagetsi.

Kachiwiri, kulumikizana kwakukulu kwa cholumikizira cha AC ndi gawo lofunikira kwambiri polumikiza chingwe chamagetsi chomwe chikubwera cha magawo atatu ndi chingwe chamagetsi chotuluka. Mawaya omwe akubwera amalembedwa kuti L1-L2-L3 ndipo mawaya omwe atuluka amalembedwa kuti T1-T2-T3. Mawaya akuluakulu nthawi zambiri amakhala otseguka ndipo amatenga gawo lofunikira pakulamulira magwiridwe antchito a mota ndi zida zina. Mawaya akuluakulu amatsimikizira kuti makina amagetsi amagwira ntchito bwino poyambitsa kuti dera litseguke kapena kutsekedwa, zomwe zimathandiza kuti zida ziziyang'aniridwa bwino.

Pomaliza, ma contactor othandizira a AC contactor amapereka ntchito yowonjezera popereka ma point otseguka nthawi zambiri (NO) ndi otsekedwa nthawi zambiri (NC). Malo otseguka nthawi zambiri amagwiritsidwa ntchito polamulira okha contactor komanso kutumiza chizindikiro cha ntchito. Mosiyana ndi zimenezi, malo otsekedwa nthawi zambiri a contactor ya AC amagwiritsidwa ntchito makamaka polumikiza ma circuit ndi kutumiza chizindikiro. Izi zimathandiza kuti ma circuit circuit azisinthasintha, zomwe zimathandiza kuti pakhale magwiridwe antchito abwino komanso chitetezo.

Mwachidule, makhalidwe atatu akuluakulu a AC contactor—coil ya AC contactor, main contact, ndi assistant contact—amatsimikizira ntchito yofunika kwambiri yomwe zigawozi zimachita mu dongosolo lamagetsi. AC contactors zimatha kusintha mphamvu zamagetsi kukhala mphamvu yamakina, kuwongolera mphamvu yamagetsi ndikupereka ntchito zina kudzera mu ma contacts othandizira. Ndi gawo lofunikira pakuwonetsetsa kuti ma circuit akuyenda bwino komanso motetezeka. Kaya amagwiritsidwa ntchito m'mafakitale kapena m'mabizinesi, makhalidwe amenewa amachititsa kuti ma contactors a AC akhale ofunikira kwambiri popereka kuwongolera kodalirika komanso kolondola kwa zida zamagetsi. Chifukwa chake, kumvetsetsa makhalidwe ofunikira awa ndikofunikira kwambiri kuti tidziwe kuyenerera ndi kugwira ntchito bwino kwa ma contactors a AC m'machitidwe osiyanasiyana amagetsi.
