Ukuthetha malunga ne-AC contactor, ndiyakholelwa ukuba abahlobo abaninzi kwishishini lomatshini kunye nombane baqhelene kakhulu nalo, luhlobo lolawulo oluphantsi lwe-voltage kwi-drag yamandla kunye nenkqubo yokulawula ngokuzenzekelayo, esetyenziselwa ukunqumla amandla, ukulawula. umsinga omkhulu kunye nomsinga omncinci.
Ngokuqhelekileyo, i-AC contactor idla ngokuqulunqwa ngamacandelo amaninzi: ukuhamba, ukufowunelwa kwe-static, uqhagamshelwano oluncedisayo, i-arc yokucima isiciko, umbindi wentsimbi ehambayo kunye ne-static kunye nezindlu zesibiyeli.Xa usebenza, i-coil ye-electromagnetic yesixhobo inamandla, kwaye ingundoqo yentshukumo yenza uqhagamshelwano loqhagamshelwano lwentshukumo.Ngeli xesha, isiphaluka sixhunyiwe.Xa i-coil ye-electromagnetic icinyiwe, isiseko sentshukumo sibuyela ngokuzenzekelayo kwisenzo, kwaye isekethe iyahlulwa.
Ngenxa yokuba i-AC yoqhagamshelwano isetyenziselwa ukuqhawula amandla kunye nesekethe yokulawula, uqhagamshelwano oluphambili lwe-contactor luvula kunye nokuvalwa kwesekethe yokubulawa, uqhagamshelwano oluncedisayo lusetyenziselwa ukwenziwa komyalelo wokulawula, ngoko ke uqhagamshelwano oluncedisayo kufuneka luvuleke kwaye ivale abafowunelwa ababini kusetyenziso oluqhelekileyo.Kufuneka sinikele ingqalelo kwinqaku elinye kukuba ngenxa yokuba i-current ephetheyo ye-AC contactor inkulu, kulula ukuhamba xa udibana nemozulu yombane, oku kungenxa yokuba i-AC contactor ngokwayo inomsebenzi wokukhusela ngokugqithisileyo kunye nokukhusela umhlaba, umgca. umbane udibene ngokuzenzekelayo unqamle unikezelo lwamandla ukukhusela izixhobo, ukuthintela umbane ophezulu, umonakalo ophezulu wangoku.
Ukongeza, ukuze kuqinisekiswe ubomi benkonzo ye-ac contactor, abantu ekukhetheni nasekuthengeni izixhobo zokunxibelelana kufuneka badibane ngcono nabasebenzi abafanelekileyo, ngokwezixhobo zabo zombane, ukusetyenziswa komthamo wokukhetha wesekethe kunye nentshukumo ehambelana ne-contactor, eyahlukileyo emanzi, i-asidi kunye nesiseko esisingqongileyo sikwafuna ukukhetha uqwalaselo olukhethekileyo lwe-ac contactor, ukuze ungabangeli ilahleko yemposiso egqithisileyo.
