1. Ukuhlelwa koxhumana nabo:
● Ngokuya nge-voltage ehlukene yekhoyili yokulawula, ingahlukaniswa: I-DC contactor ne-AC contactor
● Ngokuya ngesakhiwo sokusebenza, ihlukaniswe ngokuthi: i-electromagnetic contactor, i-hydraulic contactor kanye ne-pneumatic contactor.
● Ngokwemodi yesenzo zingahlukaniswa zibe: isithintana esiqondile esinyakazayo kanye nesixhumi esijikelezayo.
2. Isixhumi sikagesi
● Iqhaza nokuhlukaniswa kwabathintana nabo
I-electromagnetic contactor iyisekhethi yokulawula esebenzisa othintana naye oyinhloko ukuvala noma ukuphula isekethe yemoto noma isekethe yomthwalo weminye imisebenzi.Ingakwazi ukufeza ukusebenza kwebanga elide njalo, inezikhathi eziningana ezinkulu kuneyamanje yokusebenza noma izikhathi eziyishumi amandla okushintsha nokuphuka, kodwa ayikwazi ukuphula amandla wesifunda esifushane.Ngenxa yobuncane bayo, intengo ephansi kanye nokugcinwa kulula, isetshenziswa kabanzi.Ukusetshenziswa okuyinhloko kwe-contactor ukulawula ukuqala, ukuguqulwa, ukulawulwa kwesivinini kanye nokubhuleka kwemoto.Ibaluleke kakhulu futhi iyisisetshenziswa sikagesi sokulawula esivame ukusetshenziswa kakhulu ohlelweni lokulawula ukudonsa kagesi.
Ngokwesimo se-loop yokuxhumana yokuxhumana eyinhloko, ihlukaniswe yaba yi-contactor eqondile kanye ne-AC contactor.
Ngokusho kwendlela yokusebenza, ihlukaniswe yaba: i-electromagnetic contactor kanye ne-contactor kazibuthe unomphela.
Ngokwenombolo yezigxobo zothintana naye oyinhloko (okungukuthi, inombolo yoxhumana nabo abakhulu), othintana nabo be-DC bane-unipolar ne-bipolar;ama-AC contactors anezigxobo ezintathu, izigxobo ezine nezigxobo ezinhlanu.
● Umgomo wokusebenza we-contactor
Lapho ikhoyili ye-AC contactor inikwa amandla, i-flux kazibuthe ikhiqizwa engxenyeni yensimbi.Ngakho-ke, ukumunca kukhiqizwa esikhaleni se-armature, okwenza i-armature ikhiqize isenzo sokuvala, futhi othintana naye oyinhloko uvalwe yi-armature, ngakho-ke isifunda esikhulu sixhunyiwe.Ngesikhathi esifanayo, i-armature iphinde iqhube ukunyakaza kokuxhumana okusizayo, okwenza oxhumana naye ovulekile ovulekile oyisizayo avaliwe, futhi avule oxhumana naye wokuqala ovaliwe oyisizayo.Uma ikhoyili ivaliwe noma i-voltage incishisiwe kakhulu, ukumunca kuyanyamalala noma kuba buthakathaka, i-armature ivulwa ngaphansi kwesenzo se-spring spring, futhi othintana nabo abakhulu nabasizayo babuyiselwa esimweni sokuqala.
I-contactor isebenzisa othintana naye oyinhloko ukuze aphule isifunda esikhulu, kanye noxhumana naye osizayo ukuze aphule iluphu yokulawula.
