Uma ngikhuluma nge-AC contactor, ngikholelwa ukuthi abangani abaningi embonini yemishini nekagesi bajwayelene nayo kakhulu, iwuhlobo lokulawula i-voltage ephansi ohlelweni lokudonsa amandla kanye nesistimu yokulawula okuzenzakalelayo, esetshenziselwa ukudlulisa amandla, ukulawula i-current enkulu. ngomsinga omncane.
Ngokuvamile, i-AC contactor ngokuvamile yakhiwa izingxenye eziningana: ezihambayo, ukuthintana okuyinhloko okumile, ukuthintana okuyisizayo, ikhava yokucisha i-arc, insimbi ehambayo kanye ne-static core kanye nezindlu zamabakaki. Lapho usebenza, ikhoyili ye-electromagnetic yemishini iba namandla, futhi umnyombo wokunyakaza uyaxhumana. Ngalesi sikhathi, isifunda sixhunyiwe. Uma ikhoyili ye-electromagnetic icishiwe, umgogodla wokunyakaza ubuyela ngokuzenzakalelayo esenzweni, bese isekethe ihlukaniswe.
Ngenxa yokuthi i-AC contactor isetshenziswa kakhulu ukucisha nokulawula isekethe, ukuthintana okuyinhloko kwe-contactor ikakhulukazi ukuvulwa nokuvalwa kwesekethe yokubulawa, futhi othintana naye osizayo usetshenziselwa ukuyala ukwenziwa kokulawula, ngakho-ke oxhumana naye osizayo kufanele alungiselelwe. koxhumana nabo ababili ngokuvamile bavula futhi bavalwe ngokusetshenziswa okuvamile. Kudingeka sinake iphuzu elilodwa ingoba i-AC contactor ephethe i-current inkulu, kulula ukukhubeka uma ihlangana nesimo sezulu sombani, lokhu kungenxa yokuthi i-AC contactor ngokwayo inomsebenzi wokuvikela ngokweqile kanye nokuvikela phansi, umugqa uhlangabezane nombani ngokuzenzakalelayo. ukunqamula ukunikezwa kwamandla ukuvikela okokusebenza, 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 komthamo wokukhetha wesekethe kanye nemvamisa yesenzo esihambelanayo, okumanzi okuhlukile, i-asidi nemvelo yesisekelo nayo ifuna ukukhetha ukucushwa okukhethekile kwe-ac contactor, ukuze ingabangeli ukulahlekelwa kwamaphutha amaningi.
