Izixhumi ze-AC ezine-voltage ephansi zisetshenziselwa kakhulu ukuvula nokuvala ukunikezwa kwamandla kagesi, okungalawula okokusebenza kwamandla kusukela ebangeni elide, futhi kugweme ukulimala komuntu siqu lapho uvula futhi uvala ukunikezwa kwamandla kwempahla. Ukukhethwa kwe-AC contactor kubaluleke kakhulu ekusebenzeni okujwayelekile kwemishini yamandla nezintambo zikagesi.
1. Isakhiwo namapharamitha we-AC contactor
Ngokuvamile, idivayisi ye-AC contactor iyadingeka ukuze ibe nesakhiwo esihlangene, esisebenziseka kalula, isisetshenziswa esihle sikazibuthe esivuthela othintana nabo abahambayo nabamile, umphumela omuhle wokucisha i-arc, i-zero flashover, kanye nokukhuphuka okuncane kwezinga lokushisa. Ngokwendlela yokucisha i-arc, ihlukaniswe yaba uhlobo lomoya kanye nohlobo lwe-vacuum, futhi ngokwendlela yokusebenza, ihlukaniswe ngohlobo lwe-electromagnetic, uhlobo lwe-pneumatic kanye nohlobo lwe-electromagnetic pneumatic.
Imingcele ye-voltage elinganiselwe ye-contactor ihlukaniswe ngama-voltage aphezulu kanye ne-low voltage, futhi i-voltage ephansi ngokuvamile i-380V, 500V, 660V, 1140V, njll.
Umsinga kagesi uhlukaniswe waba wamanje oshintshanayo noqondile ngokuya ngohlobo. Amapharamitha amanje ahlanganisa ukulinganisa kokusebenza kwamandla, amandla okushisisa okuvunyelwene ngawo, ukwenza amandla amanje naphephukayo, amandla okushisisa okuvunyelwene ngawo koxhumana nabo abasizayo kanye nokumelana nesikhathi esifushane sokumelana ne-contactor, njll. Amapharamitha wemodeli ye-contactor evamile anika amandla okushisisa okuvunyelwene ngawo, futhi kukhona okulinganiselwe okumbalwa. imisinga esebenzayo ehambisana nokushisisa okuvunyelwene ngakho. Isibonelo, ku-CJ20-63, ukusebenza okulinganiselwe koxhumana naye oyinhloko kuhlukaniswe ku-63A no-40A. I-63 kupharamitha yemodeli ibhekisela ekushiseni okuvunyelwene ngakho, okuhlobene nesakhiwo se-insulation segobolondo le-contactor, futhi ukusebenza kwamanje okulinganiselwe kuhlobene nomthwalo wamanje okhethiwe, ohlobene nezinga le-voltage.
Amakhoyili e-AC contactor ahlukaniswe abe yi-36, 127, 220, 380V njalonjalo ngokuya nge-voltage. Inombolo yezigxobo ze-contactor ihlukaniswe ngezigxobo ezingu-2, 3, 4, 5 njalonjalo. Kunamapheya amaningana othintana nabo abasizayo ngokuya ngokuvamise ukuvuleka nokuvamise ukuvaleka, futhi akhethwa ngokwezidingo zokulawula.
Eminye imingcele ihlanganisa ukuxhuma, izikhathi zokunqamuka, ukuphila kokusebenza, ukuphila kukagesi, imvamisa yokusebenza ephezulu evunyelwe, ubukhulu bobubanzi obuvunyelwe bezintambo, ubukhulu bangaphandle nobukhulu bokufaka, njll.Ukuhlukaniswa kwabathintana nabo
Izinhlobo Zokuthintana Ezivamile
Sebenzisa ikhodi yesigaba ngesibonelo sokulayisha esijwayelekile okokusebenza okujwayelekile
