Iinxalenye kunye nomgaqo wokusebenza we-AC contactor

Izixhobo zokunxibelelana ze-ACziyinxalenye ebalulekileyo ekusebenzeni kweenkqubo ezininzi zombane. Zidlala indima ebalulekileyo ekulawuleni ukuhamba kombane nokuqinisekisa ukusebenza kakuhle kwezixhobo ezahlukeneyo kunye nezixhobo. Kweli nqaku, siza kujonga ngokunzulu izinto kunye nemigaqo yokusebenza kwee-contactors ze-AC, sicacise ukubaluleka kwazo kunye nemisebenzi yazo.

I-AC contactor ikakhulu inamacandelo amane abalulekileyo asebenzisanayo ukwenza umsebenzi wayo. Inxalenye yokuqala yinkqubo ye-electromagnetic, equlathe ikhoyili yokutsala, isiseko sesinyithi esihambayo, kunye nesiseko sesinyithi esingashukumiyo. Xa ikhoyili yokutsala inikwe amandla, iya kuvelisa amandla e-electromagnetic, aza kutsala isiseko sesinyithi esihambayo siye kwisiseko sesinyithi esingashukumiyo. Olu hambo lubalulekile ekusebenzeni ngokufanelekileyo kwekhontactor.

Inxalenye yesibini ye-AC contactor yinkqubo yoqhagamshelwano. Ibandakanya iiseti ezintathu ze-contacts eziphambili kunye neseti enye okanye ezimbini ze-contacts ezivulekileyo nezivaliweyo. Ezi contacts ziqhagamshelwe kwi-iron core ehambayo kwaye zidibene ngobuchule. Xa amandla e-electromagnetic etsala kwi-iron core, iqhuba i-contacts kunye, ibangele ukuba zivaleke. Eli nyathelo livumela ukuba umbane udlule kwi-contactor, uvumela izixhobo okanye izixhobo eziqhagamshelwe kuzo ukuba zisebenze.

Ukuqinisekisa ukusebenza ngokukhuselekileyo kwe-AC contactor, ixhotyiswe ngesixhobo sokucima i-arc, esenza inxalenye yesithathu. Olu phawu ludla ngokufumaneka kwii-contactors ezinomthamo omkhulu. I-arc yenzeka xa i-contact ephambili iphantsi kombane ophezulu kwaye emva koko ivuleka. Isixhobo sokucima i-arc sinoxanduva lokunqumla i-arc ngokukhawuleza, sithintele umonakalo kwii-contacts eziphambili kwaye siqhawule ngokulula.

Inxalenye yesine neyokugqibela yeIsixhobo soqhagamshelwano lwe-ACIqulathe indawo yokukhusela ubushushu kunye nezinye izixhobo ezahlukeneyo ezifana nezipringi, iindlela zokudlulisa umbane, izangqa zesekethe emfutshane kunye neeterminal. Ezi zinto zibalulekile ekuboneleleni ngokhuseleko kunye nokhuseleko ukuqinisekisa ukusebenza ngokufanelekileyo kunye nobomi benkonzo yecontactor.

Ukuqonda indlela ezisebenza ngayo ii-contactors ze-AC kubalulekile ekuqondeni indlela ezisebenza ngayo. Xa i-coil kwi-contactor inikwe amandla, i-static iron core ivelisa amandla e-electromagnetic. La mandla atsala i-iron core ehambayo aye kwi-iron core engashukumiyo, nto leyo ebangela ukuba ii-contacts zivaleke. Ngenxa yoko, i-AC contactor iyavulwa, isekethe iqhagamshelwe, kwaye umbane uyahamba.

Ngokwahlukileyo koko, xa ikhoyili ingasebenzi okanye iqhawukile, amandla e-electromagnetic aveliswa yi-static iron core awasekho. Ngenxa yoku, i-moving iron core iyahlukana ne-stainless iron core ngenxa yamandla okusabela entwasahlobo. Ngenxa yoko, oonxibelelwano bayavuleka kwaye umbane oya kwisixhobo esiqhagamshelweyo uyanqanyulwa. Oku kuyayiqhawula ngempumelelo isekethe kwaye kuqinisekisa ukhuseleko lwenkqubo yombane.

Ngamafutshane, i-AC contactor ineenxalenye ezine ezisisiseko ezisebenza ngokuvumelanayo ukulawula ukuhamba kombane. Ukusebenza kwazo ngokufanelekileyo kubalulekile ekusebenzeni kakuhle kofakelo kunye nezixhobo ezahlukeneyo. Ukuqonda ukwakheka kunye nemigaqo yokusebenza kwee-AC contactors kusenza siqonde ukubaluleka kwazo kwaye siqinisekise ukusetyenziswa kwazo ngokufanelekileyo kwiinkqubo zombane.
