Uma ngikhuluma nge-AC contactor, ngikholelwa ukuthi abangani abaningi embonini yemishini nekagesi bajwayelene kakhulu nayo, iwuhlobo lokulawulwa kwamandla kagesi aphansi ohlelweni lokudonsa nokulawula okuzenzakalelayo, olusetshenziselwa ukunqamula amandla, ukulawula amandla amakhulu amancane okwamanje.
Ngokuvamile, isixhumi se-AC sivamise ukwakhiwa ngokuthintana okuyinhloko okuguquguqukayo nokumile, ukuthintana okuyisizayo, ikhava yokucisha i-arc, ingqikithi yensimbi eguquguqukayo nemile kanye negobolondo labakaki.Lapho usebenza, ikhoyili kagesi yemishini inikwa amandla, bese kuthintwa othintana nabo abaguqukayo nabamile ngenxa yomongo wokumunca.Ngalesi sikhathi, isifunda sixhunyiwe.Uma ikhoyili ye-electromagnetic icishiwe, umgogodla onyakazayo ubuyela ngokuzenzakalelayo esenzweni, futhi okuthintana naye okuguquguqukayo kuyahlukaniswa, futhi isekethe iyahlukaniswa.
Ngenxa yokuthi i-AC contactor isetshenziswa kakhulu ukucisha nokulawula amasekhethi, ukuthintana okuyinhloko kwe-contactor ikakhulukazi ukwenza ukuvula nokuvala isekethe, futhi ukuthintana okuyisizayo kusetshenziselwa ukulawula ukulawulwa kwemiyalelo, ngakho-ke oxhumana naye osizayo kufanele. yiba noxhumana nabo ababili endaweni evamile evulekile futhi evaliwe ekusetshenzisweni okuvamile.Okudingayo ukunaka iphuzu elilodwa ukuthi ngenxa yokuthi i-current current ye-AC contactor inkulu, kulula ukukhubeka uma umbani.Lokhu kungenxa yokuthi i-AC contactor ngokwayo inomsebenzi wokuvikela okudlulele kanye nokuphansi.Lapho umbani, ulayini unqamula ngokuzenzakalelayo ukunikezwa kwamandla ukuze kuvikelwe okokusebenza futhi kuvinjwe umonakalo nge-voltage ephezulu kanye namandla aphezulu.
Ngaphezu kwalokho, ukuze kuqinisekiswe impilo yesevisi ye-ac contactor, abantu abasemishini yokuxhumana yokuthenga kungcono kakhulu bangathintana nabasebenzi abafanelekile, ngokuya ngezinto zabo zikagesi, ukusetshenziswa komthamo wokukhetha wesekethe kanye ne-action frequency contactor ehambisanayo, okuhlukile okumanzi, imvelo ye-asidi ne-alkali nayo kufanele ikhethe ukucushwa okukhethekile kwe-ac contactor, ukuze kugwenywe iphutha eleqile.
