Ukuthetha nge-AC contactor, ndiyakholelwa ukuba abahlobo abaninzi kwishishini lomatshini kunye nombane baqhelene kakhulu nalo, luhlobo lolawulo lwamandla aphantsi kwi-drag yamandla kunye nenkqubo yokulawula ngokuzenzekelayo, esetyenziselwa ukunqumla amandla, ukulawula umsinga omkhulu kunye nomncinci. yangoku.
Ngokuqhelekileyo, i-AC contactor idla ngokuqulunqwa ngoqhagamshelwano olutshintshayo kunye ne-static, uqhagamshelwano oluncedisayo, isiciko sokucima i-arc, undoqo wentsimbi oguqukayo kunye ne-static kunye neqokobhe lesibiyeli.Xa usebenza, i-coil ye-electromagnetic yesixhobo inamandla, kunye noqhagamshelwano oluguquguqukayo kunye noluzinzileyo ngenxa yondoqo wokufunxa.Ngeli xesha, isiphaluka sixhunyiwe.Xa i-coil ye-electromagnetic icinyiwe, i-core ehambayo ibuyela ngokuzenzekelayo kwisenzo, kwaye abafowunelwa abaguquguqukayo bayahlulwa, kwaye isiphaluka sahluliwe.
Ngenxa yokuba i-AC contactor isetyenziselwa ukucima umbane kunye nokulawula iisekethe, uqhagamshelwano oluphambili lwe-contactor lukwenza ukuvulwa kunye nokuvalwa kwesekethe, kwaye uqhagamshelwano oluncedisayo lusetyenziselwa ukulawulwa kokulawulwa kwemiyalelo, ngoko uqhagamshelwano oluncedisayo kufuneka. Yiba nabafowunelwa ababini kwindawo eqhelekileyo evulekileyo kwaye ivale kusetyenziso oluqhelekileyo.Into ekufuneka sinikele ingqalelo kuyo inqaku kukuba ngenxa yokuba umsinga wonxibelelwano we-AC mkhulu, kulula ukukhubeka xa umbane wemozulu.Oku kungenxa yokuba i-AC contactor ngokwayo inomsebenzi we-overcurrent kunye nokukhusela umhlaba.Xa umbane, umgca unqumle ngokuzenzekelayo unikezelo lwamandla ukukhusela izixhobo kunye nokuthintela umonakalo ngombane ophezulu kunye nokuphezulu kwangoku.
Ukongeza, ukuze kuqinisekiswe ubomi benkonzo ye-ac contactor, abantu abakwi-contactor yokuthenga izixhobo kungcono banokubonisana nabasebenzi abafanelekileyo, ngokwezixhobo zabo zombane, ukusetyenziswa komthamo wokukhetha wesekethe kunye ne-frequency ye-frequency ehambelana ne-contactor, eyahlukileyo emanzi, i-asidi kunye ne-alkali bume kufuneka ikhethe uqwalaselo olulodwa lwe-ac contactor, ukuze kuthintelwe impazamo egqithisileyo.
