Ama-Schneider magnetic ac contactors

I-Schneider magnetic AC contactor itholakala ezingeni eliphezulu le-thermal protection relay ukuze ixhume noma inqamule ulayini wokuphakelwa kwamandla kagesi. Othintana naye oyinhloko we-contactor ixhunywe emshinini kagesi, futhi ikhoyili ixhunywe kusishintshi sokulawula. Uma i-contactor yonakalisiwe, inani lokumelana loxhumene naye kanye nekhoyili izotholwa. Umdwebo ubonisa umdwebo ojwayelekile wezintambo zokulawula imoto
Ngaphambi kokutholwa, amatheminali we-contactor ahlonzwa ngokuya ngokuhlonza kundlu yokuxhumana. Ngokokuhlonza, amatheminali 1 kanye no-2 amatheminali omugqa wesigaba L1, amatheminali 3 kanye no-4 amatheminali esigaba 12, amatheminali 5 kanye no-6 amatheminali omugqa wesigaba L3, amatheminali 13 kanye no-14 ayizixhumi ezisizayo, futhi A1 kanye no-A2 amakhoyili amatheminali okuhlonza amaphini.
Ukuze wenze umphumela wesondlo unembile, isixhumi se-AC singasuswa emugqeni wokulawula, bese emva kokuqoqwa kwetheminali yezintambo kungahlulelwa ngokuya ngokuhlonza, futhi i-multimeter ingashintshwa ibe “isikhathi sokumelana ne-100″. ukubona inani lokumelana lekhoyili yokuxhumana. Faka amapeni ewashi abomvu namnyama kutheminali yezintambo exhunywe kukhoyili, futhi ngaphansi kwezimo ezivamile, inani lokumelana elilinganiselwe lingu-1,400 Ω. Uma ukumelana kungapheli noma ukumelana kungu-0, i-contactor yonakalisiwe. Isibalo sibonisa inani lokumelana lekhoyili yokuthola
Ngokusho kokuhlonza othintana naye, kokubili othintana nabo abakhulu kanye noxhumana nabo abasizayo be-contactor bavame ukuvuleka othintana nabo. Amapeni ewashi abomvu namnyama abekwa kutheminali yezintambo yanoma iyiphi indawo yokuxhumana, futhi inani lokumelana elilinganiselwe alinamkhawulo. Isibalo sibonisa inani lokumelana noxhumana nabo abatholiwe.
Lapho ibha ephansi icindezelwa ngesandla, othintana naye uzovala, amapeni etafula abomvu namnyama ngeke anyakaze, futhi ukumelana okulinganiselwe kuba ngu-0. Umfanekiso ubonisa inani lokumelana kothintana naye ngokucindezela ibha ephansi.
