Uma ngikhuluma nge-AC contactor, ngikholwa ukuthi abangani abaningi embonini yemishini nekagesi bajwayelene kakhulu nayo.Iwuhlobo lokulawula okunogesi ophansi kusistimu yokudonsa amandla kanye ne-othomathikhi, esetshenziselwa ukunqamula amandla, nokulawula i-current enkulu ngomsinga omncane.
Ngokuvamile, isixhumi se-AC sivame ukwakhiwa izingxenye eziningana: ukunyakaza, ukuthintana okuyinhloko okumile, ukuthintana okuyisizayo, isihlangu se-arc, ukunyakaza, umgogodla wensimbi omile kanye nezindlu zamabakaki. nokuxhumana okuguquguqukayo kuthintwa ngenxa yokumunca.Lapho isifunda sixhunyiwe.Uma ikhoyili ye-electromagnetic icishiwe, umgogodla onyakazayo ubuyiselwa ngokuzenzakalelayo, futhi ukunyakaza nokuxhumana okuguquguqukayo kuyahlukaniswa, futhi isekethe iyahlukaniswa.
Ngenxa yokuthi othintana nabo be-AC basetshenziselwa kakhulu ukunqanyulwa kwamandla kanye nesekethe yokulawula, lapho ukuthintana okuyinhloko kwe-contactor ikakhulukazi ukwenza ukuvulwa nokuvala kwesekethe, futhi othintana naye osizayo usetshenziselwa ukuyala ukulawulwa kokulawula, oxhumana naye osizayo kufanele. zilungiselele othintana nabo ababili abavame ukuvuleka nokuvala ngesikhathi sokusetshenziswa okujwayelekile.Kufanele kunakwe lokho ngoba i-AC contactor ephethe i-current inkulu, kulula ukukhubeka uma uhlangana nesimo sezulu sombani, lokhu kungenxa yokuthi i-AC contactor ngokwayo ine-overcurrent. kanye nekhono lokuvikela umhlabathi, umugqa uhlangabezane nombani unqamule ngokuzenzakalelayo ukunikezwa kwamandla ukuze kuvikelwe imishini, ukuvimbela i-voltage ephezulu, umonakalo omkhulu wamanje.
Ngaphezu kwalokho, ukuze kuqinisekiswe impilo yesevisi ye-AC contactor, abantu abakhetha futhi bathenge imishini yokuxhumana kufanele baxhumane kangcono nabasebenzi abafanelekile, ngokuya ngezinto zabo zikagesi, ukusetshenziswa kwesekethe ukukhetha umthamo kanye nemvamisa yesenzo esihambelanayo, okuhlukile okumanzi. , imvelo ye-asidi nesisekelo nayo ifuna ukukhetha ukucushwa okukhethekile kwe-AC contactor, ukuze ungagwemi ukulahlekelwa okuningi okubangelwa ukulahlekelwa.
