AC Qhagamshelana Definition
AC Qhagamshelana Inkcazelo:
Umnxibelelanisi we-AC Licandelo lolawulo oluphakathi; inzuzo yayo kukuba iyakwazi ukudibanisa rhoqo kwaye ikhuphe imigca kwaye ilawule imisinga emikhulu kunye nemisinga encinci. Ukusebenza nge-thermal overload relay kunokubonelela ngokhuseleko lomthwalo ogqithisiweyo kwisixhobo somthwalo. I-AC contactor sesona sixhobo sisetyenziswa kakhulu kwi-low-voltage control kulawulo oluzenzekelayo kunye neenkqubo zokuqhuba zombane.
Ukusebenza koMnxibelelanisi we-AC:
Ngokubanzi a isigaba sesithathu contactor Inamanqaku asibhozo ewonke: amagalelo amathathu, iziphumo ezintathu, kunye neendawo ezimbini zokulawula. Imveliso kunye negalelo ziyahambelana. Ukuba ufuna ukongeza ukuzitshixa, kufuneka kwakhona uqhagamshele umgca ukusuka kwenye yeetheminali zokuphuma kwindawo yolawulo. Umgaqo we-AC contactor kukusebenzisa umbane wangaphandle ukunika amandla ikhoyili kunye nokuvelisa intsimi ye-electromagnetic. Xa amandla esetyenziswa, indawo yoqhagamshelwano iyanqanyulwa. Abafowunelwa bekhoyili ababini badla ngokufumaneka ezantsi kwe-contactor, enye kwicala ngalinye. Amanye amagalelo kunye neziphumo zidla ngokuba phezulu. Kwakhona, nikela ingqalelo kwi-voltage yonikezelo lwamandla lwangaphandle kunye nokuba ngaba abafowunelwa bavalwa ngokuqhelekileyo okanye bavulwa ngokuqhelekileyo.
Xa ikhoyili yenziwe amandla, umbindi wentsimbi emile uvelisa umtsalane we-electromagnetic, otsala umbindi wentsimbi oshukumayo kunye. Ekubeni inkqubo yoqhagamshelwano idityaniswe nentsimbi ehambayo, iqhuba abafowunelwa abathathu abahambayo ukuba bahambe ngaxeshanye, bavale abafowunelwa abaphambili. Xa uqhagamshelwano oluphambili luvala, uqhagamshelwano oluncedisayo oluqhelekileyo oluvaliweyo luqhagamshelwe ngomatshini kuqhagamshelwano oluphambili luvula, kwaye uqhagamshelwano oluqhelekileyo oluvulekileyo oluncedisayo luyavala, ngaloo ndlela luvula umbane. Xa i-coil i-de-energized, amandla okufunxa ayanyamalala, kwaye inxalenye edibanisayo yentsimbi ehambayo iyahlukana ngenxa ye-spring reaction force. Oku kubangela ukuba uqhagamshelwano oluphambili luvuleke, uqhagamshelwano oluncedisayo oluqhele ukuvalwa ngoomatshini oluqhagamshelwe kuqhagamshelwano oluphambili luvale, kunye noqhagamshelo oluqhelekileyo oluvulelekileyo oluncedisayo ukuze luvuleke, ngaloo ndlela kunqunyulwa unikezelo lwamandla.
Umnxibelelanisi we-AC uphethe umsinga omkhulu. Ukusebenza kwayo ngokuqhelekileyo kulawulwa yi-coil yokutsala yangaphakathi, kwaye i-coil yokulawula iqhutywe ngeentlobo ezininzi ze-relays ezixhunyiwe kwi-series kunye nayo.
Isiphelo:
Kwihlabathi elikhulu lombane kunye ne-electronics, kukho iindidi ezahlukeneyo zoqhagamshelwano. Ziyakwazi ukwahlulwa ngokwezo unikezelo lwangoku, inani leepali, uhlobo lomthwalo, ulwakhiwo kunye neendidi zenkonzo.
