1. Ukuhlelwa kwabafowunelwa:
● Ngokwe-voltage eyahlukeneyo yekhoyili yolawulo, inokwahlulwa ibe yi: DC contactor kunye ne-AC contactor
● Ngokwesakhiwo sokusebenza, yahlulwe yaba: i-electromagnetic contactor, i-hydraulic contactor kunye ne-pneumatic contactor.
● Ngokwemowudi yesenzo inokwahlulwa ibe: i-contactor yentshukumo ngqo kunye ne-rotary contactor.
2. I-Electromagnetic contactor
● Indima kunye nokuhlelwa kwabafowunelwa
I-Electromagnetic contactor yisekethe yolawulo esebenzisa uqhagamshelwano oluphambili ukuvala okanye ukwaphula isekethe yemoto okanye isekethe yomthwalo weminye imisebenzi.Iyakwazi ukufikelela rhoqo umgama omde wokusebenza, unamaxesha amaninzi amakhulu kunomsebenzi wangoku okanye namaxesha alishumi okutshintsha kunye nokuqhawula amandla, kodwa ayikwazi ukwaphula isiphaluka esifutshane.Ngenxa yobukhulu bayo obuncinci, ixabiso eliphantsi kunye nokugcinwa lula, lisetyenziswa ngokubanzi.Ukusetyenziswa okuphambili kwe-contactor kukulawula ukuqala, ukuguqulwa, ukulawulwa kwesantya kunye ne-braking ye-motor.Yeyona nto ibalulekileyo kunye neyona nto isetyenziswayo yokulawula isixhobo sombane kwinkqubo yokulawula ukutsalwa kombane.
Ngokwefom yelophu yoqhagamshelwano oluphambili, yahlulwe yaba yi-contactor ngqo kunye ne-AC contactor.
Ngokwendlela yokusebenza, yahlulwe yaba: i-electromagnetic contactor kunye ne-magnetic contactor esisigxina.
Ngokwenani leepali zoqhagamshelwano oluphambili (oko kukuthi, inani labafowunelwa abaphambili), abafowunelwa be-DC abakwi-unipolar kunye ne-bipolar;ii-AC zoqhagamshelwano zineepali ezintathu, iipali ezine kunye neepali ezintlanu.
● Umgaqo wokusebenza womnxibelelanisi
Xa i-coil ye-AC ye-contactor inikwe amandla, i-flux magnetic yenziwa kwi-core core.Ngoko ke, ukufunxa kuveliswa kwi-gap ye-armature, okwenza i-armature ivelise isenzo sokuvala, kwaye uqhagamshelwano oluphambili luvalwe yi-armature, ngoko ke isiphaluka esiphambili sixhunyiwe.Kwangaxeshanye, i-armature iphinda iqhube intshukumo yoqhagamshelwano encedisayo, yenza unxibelelwano lwangaphambili oluvulekileyo lwe-axiliary luvalwe, kwaye luvule unxibelelwano lwangaphambili oluvaliweyo.Xa i-coil ivaliwe okanye i-voltage iyancipha kakhulu, i-suction iyanyamalala okanye iyancipha, i-armature ivuliwe phantsi kwesenzo sokukhutshwa kwentwasahlobo, kwaye oonxibelelwano oluphambili kunye nabancedisayo babuyiselwa kwimeko yokuqala.
I-contactor isebenzisa uqhagamshelwano oluphambili ukuphula isiphaluka esiphambili, kunye noqhagamshelwano oluncedisayo ukuphula i-loop yokulawula.
