Isimiso sokusebenza se-AC contactor kanye nencazelo yesakhiwo sangaphakathi

I-AC contactor iyi-electromagnetic AC contactor evame ukuvuleka othintana nabo abakhulu, izigxobo ezintathu, nomoya njengesici sokucisha i-arc. Izingxenye zayo zifaka: ikhoyili, indandatho yesifunda esifushane, umgogodla wensimbi omile, umgogodla wensimbi onyakazayo, ukuthintana okunyakazayo, ukuthintana okumile, ukuthintana okuvamise ukuvuleka, ukuthintana okuvamise ukuvaleka, ucezu lwesiphepho sokucindezela, isiphethu sokuphendula, isiphethu se-buffer, Isembozo sokucisha i-arc nokunye kwasekuqaleni. izingxenye, abathintwayo be-AC bane-CJO, i-CJIO, i-CJ12 neminye imikhiqizo yochungechunge.
Uhlelo lwe-electromagnetic: Luhlanganisa ikhoyili, umongo wensimbi omile kanye nensimbi ehambayo (eyaziwa nangokuthi i-armature).
Isistimu yokuxhumana: Ihlanganisa othintana nabo abakhulu kanye noxhumana nabo abasizayo. Othintana naye oyinhloko uvumela i-current enkulu ukuthi idlule futhi inqamule isekethe enkulu. Ngokuvamile, ubuningi bamanje (okungukuthi i-current rated) evunyelwe othintana naye oyinhloko isetshenziswa njengenye yemingcele yezobuchwepheshe ye-contactor. Oxhumana nabo abasizayo bavumela kuphela i-current encane ukuthi idlule, futhi ngokuvamile ixhunywe kumjikelezo wokulawula lapho isetshenziswa.
Othintana nabo abakhulu be-AC contactor ngokuvamile bavula othintana nabo, futhi abathintwayo abasizayo bavamise ukuvuleka noma kuvame ukuvalwa. I-contactor ene-current encane elinganiselwe inabasizi abane; isixhumi esinamandla amakhulu akalwe sinabasekeli abayisithupha. Othintana nabo abathathu abakhulu be-CJ10-20 contactor ngokuvamile bavuliwe; inoxhumana nabo abane abayisiza, ababili abavamise ukuvuleka kanti ababili bavamise ukuvaleka.
Okubizwa ngokuvamise ukuvuleka nokuvamise ukuvaleka kubhekise kusimo sothintana naye ngaphambi kokuthi isistimu kazibuthe kagesi inganikwa amandla. Ukuthintana okuvamise ukuvuleka, okubuye kwaziwe njengokuthintana okunyakazayo, ukuthintana okuvalekile kusho ukuthi uma ikhoyili ingenawo amandla, othintana nabo abahambayo nabamile bayavaleka:. Ngemva kokuba ikhoyili inikwe amandla, iyanqanyulwa, ngakho-ke oxhumana naye ovamise ukuvaleka ubizwa nangokuthi i-dynamic contact.
Idivaysi yokucisha i-arc Ukusetshenziswa kwedivayisi yokucisha i-arc ukusika ngokushesha i-arc lapho kuvulwa othintana naye oyinhloko. Kungabhekwa njengomfula omkhulu. Uma inganqanyulwa ngokushesha, ukuculwa kokuxhumana okuyinhloko kanye nokushisela kuzokwenzeka, ngakho-ke ama-AC Contactors ngokuvamile anemishini yokucisha i-arc. Koxhumana nabo be-AC abanomthamo omkhulu, amagridi okucisha ama-arc avame ukusetshenziselwa ukuvimbela i-arcing.
Isakhiwo sesimiso sokusebenza sesixhumi se-AC siboniswa emfanekisweni ongakwesokudla. Uma ikhoyili inikwa amandla, umgogodla we-iron udonsa uzibuthe, ukuheha i-armature ukuthi iye phansi, ukuze kuthintwa okuvamise ukuvaleka kunqanyulwe futhi okuvamise ukuvuleka kuvalwe. Lapho ikhoyili ivaliwe, amandla kazibuthe ayanyamalala, futhi ngaphansi kwesenzo samandla okusabela entwasahlobo, i-armature ibuyela endaweni yayo yasekuqaleni, noma ngabe abathintwayo babuyela esimweni sabo sasekuqaleni.
