AC Contactor Definition
Incazelo Yesixhumi se-AC:
Isixhumi se-AC Kuyingxenye yokulawula okuphakathi; inzuzo yayo ukuthi ingaxhuma njalo futhi inqamule imigqa futhi ilawule imisinga emikhulu ngemisinga emincane. Ukusebenza nge-thermal overload relay kungase futhi kunikeze ukuvikelwa kokulayisha ngokweqile kwempahla yokulayisha. I-AC contactor futhi iyidivayisi esetshenziswa kakhulu yokulawula i-low-voltage ekulawuleni okuzenzakalelayo kanye nezinhlelo zokushayela zikagesi.
I-AC Contactor Operation:
Ngokuvamile a isixhumi esinezigaba ezintathu Inamaphuzu ayisishiyagalombili esewonke: okokufaka okuthathu, okuphumayo okuthathu, namaphoyinti okulawula amabili. Okukhiphayo nokokufaka kuyahambisana. Uma ufuna ukwengeza ukuzikhiya, udinga futhi ukuxhuma umugqa osuka kwenye yamatheminali okukhiphayo uye endaweni yokulawula. Umgomo we-AC contactor ukusebenzisa amandla angaphandle ukuze unike amandla ikhoyili futhi ukhiqize insimu ye-electromagnetic. Uma amandla esetshenziswa, indawo yokuxhumana iyanqanyulwa. Amakhoyili amabili othintana nawo ngokuvamile atholakala ngaphansi kwe-contactor, eyodwa ohlangothini ngalunye. Okunye okokufaka nokuphumayo kuvamise ukuba phezulu. Futhi, naka amandla kagesi angaphandle nokuthi abathintwayo bavamise ukuvaleka noma bavamise ukuvuleka.
Lapho ikhoyili inikwa amandla, i-static iron core ikhiqiza ukukhanga kukagesi, okudonsa umongo wensimbi onyakazayo ndawonye. Njengoba isistimu yokuxhumana ixhunywe kumongo wensimbi onyakazayo, ishayela othintana nabo abathathu abahambayo ukuthi banyakaze kanyekanye, ivale abathintwayo abakhulu. Lapho othintana naye oyinhloko evala, oxhumana naye oyisisizi ovame ukuvaleka oxhunywe koxhumene naye oyinhloko uyavuleka, bese kuthi oxhumana naye ovamise ukuvuleka uyavala, ngaleyo ndlela uvule ukunikezwa kwamandla. Lapho ikhoyili iphelelwa amandla, amandla okumunca ayanyamalala, futhi ingxenye exhumayo yensimbi ehambayo iyahlukana ngenxa yamandla okusabela entwasahlobo. Lokhu kubangela ukuthi othintana naye oyinhloko avuleke, oxhumana naye ovamise ukuvaleka ongumsizi oxhunywe koxhumene naye oyinhloko avale, kanye nokuxhumana okuyisisizi okuvamise ukuvuleka kuvuleke, ngaleyo ndlela kunqandwe ukunikezwa kwamandla.
Isixhumi se-AC siphethe umsinga omkhulu. Ukusebenza kwayo ngokuvamile kulawulwa ikhoyili yokudonsa yangaphakathi, futhi ikhoyili yokulawula isetshenziswa izinhlobo eziningana zama-relay axhunywe ochungechungeni nayo.
Isiphetho:
Emhlabeni omkhulu kagesi nezinto zikagesi, kunezinhlobo ezahlukene zoxhumana nabo. Bangahlukaniswa ngezabo ukuhlinzeka kwamanje, inombolo yezigxobo, uhlobo lomthwalo, izakhiwo kanye nezigaba zesevisi.
