Umnxibelelanisi sisixhobo solawulo oluzenzekelayo. Isetyenziselwa ikakhulu ukudibanisa rhoqo okanye ukuqhawula, isekethe ye-dc, enomthamo omkhulu wokulawula, inokusebenza umgama omde, kunye ne-relay inokuqonda ukusebenza kwexesha, ukulawulwa kwe-interlocking, ulawulo lobungakanani kunye nokulahlekelwa kwengcinezelo kunye nokukhuselwa kwe-undervoltage, esetyenziswa ngokubanzi kwisekethe yokulawula ngokuzenzekelayo, eyona nto iphambili kuyo. into yokulawula yimoto, ingasetyenziselwa ukulawula omnye umthwalo wamandla, njengesifudumezi sombane, ukukhanyisa, umatshini wokuwelda, ibhanki ye-capacitor, njl. isekethe, kodwa inefuthe eliphantsi lokukhutshwa kombane. Umthamo wolawulo lomnxibelelanisi mkhulu. Ilungele ukusebenza rhoqo kunye nolawulo olukude. Lelinye lawona macandelo abalulekileyo kwinkqubo yolawulo oluzenzekelayo. Kwimizi-mveliso yombane, kukho iimodeli ezininzi zonxibelelwano, okwangoku kwi-5A-1000A, ukusetyenziswa kwayo kubanzi kakhulu.
Ngokweentlobo ezahlukeneyo zangoku eziphambili, abafowunelwa banokwahlulwa babe yi-AC contactor kunye ne-DC contactor.
Umgaqo: i-contactor iqulunqwe kakhulu yinkqubo ye-electromagnetic, inkqubo yoqhagamshelwano, isixhobo sokucima i-arc kunye nezinye iindawo. Umgaqo we-electromagnetic contactor kukuba xa i-coil ye-electromagnetic ye-contactor inikwe amandla, iya kuvelisa indawo eyomeleleyo yamagnetic, ukuze umbindi we-static uvelise ukutsalwa kwe-electromagnetic ukutsala i-armature, kwaye uqhube isenzo soqhagamshelwano: rhoqo uvale umnxibelelwano unqanyuliwe. , rhoqo ukuvula uqhagamshelwano luvaliwe, ezi zimbini zidityanisiwe. Xa i-coil ivaliwe, i-electromagnetic suction iyanyamalala, kwaye i-armature ikhutshwe phantsi kwesenzo sokukhululwa kwentwasahlobo, ukubuyisela umnxibelelwano: uqhagamshelwano oluqhelekileyo oluvaliweyo luvaliwe kwaye uqhagamshelwano oluqhelekileyo oluvulekile luvaliwe.
