Contactor ndi chida chowongolera chodziwikiratu.Amagwiritsidwa ntchito pafupipafupi kapena kulumikizidwa pafupipafupi, dera la dc, lokhala ndi mphamvu yayikulu yolamulira, limatha kugwira ntchito mtunda wautali, ndi chingwe cholumikizira amatha kuzindikira nthawi yayitali, kuwongolera kolumikizana, kuwongolera kuchuluka ndi kutayika kwamphamvu ndi chitetezo cha undervoltage, chomwe chimagwiritsidwa ntchito kwambiri poyang'anira dera, chachikulu chake. kulamulira chinthu ndi galimoto, angagwiritsidwenso ntchito kulamulira katundu wina mphamvu, monga chotenthetsera magetsi, kuyatsa, kuwotcherera makina, capacitor banki, etc. contactor osati kulumikiza ndi kudula dera, komanso ali otsika voteji kumasulidwa. chitetezo mphamvu.The contactor ulamuliro mphamvu ndi lalikulu.Zoyenera kugwira ntchito pafupipafupi komanso kuwongolera kutali.Ndi chimodzi mwa zigawo zofunika kwambiri mu dongosolo basi kulamulira.Mu mafakitale magetsi, pali zitsanzo zambiri za contactors, panopa mu 5A-1000A, ntchito yake ndi yaikulu ndithu.
Malinga ndi mitundu yosiyanasiyana ya panopa, contactors akhoza kugawidwa mu AC contactor ndi DC contactor.
Mfundo: contactor makamaka wapangidwa ndi maginito dongosolo, kukhudzana dongosolo, arc kuzimitsa chipangizo ndi mbali zina.Mfundo ya electromagnetic contactor ndi yakuti pamene koyilo yamagetsi ya contactor imapatsidwa mphamvu, idzatulutsa mphamvu ya maginito, kotero kuti chigawo chokhazikika chimapanga mphamvu yamagetsi kuti ikope armature, ndikuyendetsa kukhudzana: nthawi zambiri kutseka kukhudzana kosagwirizana. , nthawi zambiri kutsegula kukhudzana kutsekedwa, awiriwa amagwirizana.Koyiloyo ikazimitsidwa, kuyamwa kwamagetsi kumasowa, ndipo chidacho chimatulutsidwa pansi pa kasupe wotulutsa, ndikubwezeretsanso kukhudzana: kulumikizidwa komwe kumatsekedwa kumatsekedwa ndipo kulumikizidwa komwe kumatseguka kumachotsedwa.
