I-Magnetic ac contactor 9A ukuya ku-95A

1. Indlela yokubona i-AC contactor
Umnxibelelanisi we-AC ubekwe kwinqanaba eliphezulu le-relay yokukhusela i-thermal ukuxhuma okanye ukuqhawula umgca wokubonelela umbane wesixhobo.Uqhagamshelwano oluphambili lwe-contactor luxhunyiwe kwisixhobo sombane, kwaye i-coil ixhunyiwe kwi-switch control switch.Ukuba i-contactor yonakalisiwe, ixabiso lokumelana nomnxeba kunye nekhoyili iya kubonwa.Umzobo ubonisa umzobo oqhelekileyo wokulawula i-motor wiring diagram
Ngaphambi kokufunyanwa, ii-terminals ze-contactor zichongwa ngokuchongwa kwi-contactor housing.Ngokutsho kokuchongwa, iitheminali 1 kunye no-2 ziziitheminali zomgca wesigaba L1, iitheminali 3 kunye no-4 ziitheminali zomgca wesigaba 12, iitheminali 5 kunye no-6 ziitheminali zomgca wesigaba L3, iitheminali 13 kunye ne-14 zii-axiliary contacts, kunye ne-A1 kunye ne-A2. ziitheminali zekhoyili zokuchongwa kwephini.
Ukuze wenze isiphumo sogcino sichaneke, i-AC contactor inokususwa kumgca wolawulo, kwaye emva kokuba iqela le-terminal ye-wiring igwetywe ngokuchongwa, kwaye i-multimeter inokulungiswa kwi-"100" ixesha lokumelana. ukufumanisa ixabiso lokumelana nekhoyili yoqhagamshelwano.Beka iipeni zokubukela ezibomvu kunye ezimnyama kwi-terminal ye-wiring exhunywe kwikhoyili, kwaye phantsi kweemeko eziqhelekileyo, ixabiso elilinganisiweyo lokumelana yi-1,400 Ω.Ukuba ukuchasana akupheli okanye ukuxhathisa yi-0, i-contactor yonakalisiwe.Umzobo ubonisa ixabiso lokumelana nekhoyili yokufumanisa
Ngokuchongwa kwe-contactor, bobabini abafowunelwa abaphambili kunye nabancedisi abancedisayo be-contactor bahlala bevula oonxibelelwano.Iipeni zokubukela ezibomvu nezimnyama zibekwe kwi-terminal ye-wiring yayo nayiphi na indawo yoqhagamshelwano, kwaye ixabiso elilinganisiweyo lokumelana lingenasiphelo.Umzobo ubonisa ixabiso lokumelana nabafowunelwa abachongiweyo.
Xa ibha ephantsi icinezelwe ngesandla, umnxibelelwano uya kuvala, iipeni zetafile ezibomvu kunye ezimnyama aziyi kuhamba, kwaye ukuchasana okulinganisiweyo kuba ngu-0. Umzobo ubonisa ixabiso lokumelana nomnxeba ngokucinezela ibha ephantsi.
