Ukuthetha nge-AC contactor, ndiyakholelwa ukuba abahlobo abaninzi kwishishini lomatshini kunye nombane baqhelene kakhulu nalo, luhlobo lolawulo lwamandla aphantsi kwi-drag yamandla kunye ne-automatic control system, esetyenziselwa ukudlulisa umbane, ukulawula umbane omkhulu. ngomsinga 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.Ngeli xesha, isiphaluka sixhunyiwe.Xa i-coil ye-electromagnetic icinyiwe, isiseko sentshukumo sibuyela ngokuzenzekelayo kwisenzo, kwaye isekethe iyahlulwa.
Ngenxa yokuba i-AC contactor isetyenziselwa ukucima umbane kunye nokulawula isiphaluka, uqhagamshelwano oluphambili lwe-contactor ikakhulu ukuvulwa kunye nokuvalwa kwesekethe yokubulawa, kunye noqhagamshelwano oluncedisayo lusetyenziselwa ukuyalela ukulawulwa kokulawulwa, ngoko uqhagamshelwano oluncedisayo kufuneka lulungiswe. kubafowunelwa ababini bahlala bevula kwaye bavale kusetyenziso oluqhelekileyo.Kufuneka sinikele ingqalelo kwinqaku elinye kukuba i-AC contactor ethwele yangoku inkulu, kulula ukuhamba xa udibene nemozulu yombane, oku kungenxa yokuba i-AC contactor ngokwayo inomsebenzi wokukhuselwa kwe-overcurrent kunye nomgangatho, umgca udibene nombane ngokuzenzekelayo. ukucima unikezelo lwamandla ukukhusela izixhobo, ukuthintela amandla ombane aphezulu, umonakalo omkhulu 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, iasidi kunye nokusingqongileyo kwesiseko nazo zifuna ukukhetha uqwalaselo olukhethekileyo lwe-ac contactor, ukuze ingabangeli ilahleko ezigqithisileyo.
