Umgaqo we-AC contactor kukuba amandla atsalwa, uqhagamshelwano oluphambili luvaliwe kwaye luvuliwe, kwaye i-motor igijima.Eli nqaku lazisa i-self-locking yesekethe ye-AC contactor kwaye yintoni i-self-locking ye-contactor
1. Yima iqhosha
I-wiring yeqhosha lokumisa kufuneka liqhagamshelwe kuqhagamshelwano oluqhelekileyo oluvaliweyo.Yintoni edla ngokuvalwa?Uyakwazi ukuyiqonda ngolu hlobo, ukuba asicinezeli iqhosha lokuyeka, iqhosha lokumisa lihlala livuliwe, cofa iqhosha lokuyeka ukuqhawula, kwaye ukhulule iqhosha lokuyeka, lisaxhunyiwe, ngoko kulula ukuyiqonda!
2. Iqhosha lokuqala
Iqhosha lokuqala kufuneka liqhagamshelwe kumfowunelwa ovulwa ngokuqhelekileyo.Unako kwakhona ukuqonda okuvulwa ngokuqhelekileyo njengeqhosha lokumisa.Iqhosha lokuqala lihlala likhutshiwe ukuba asicofa iqhosha lokuqala.Cinezela iqhosha lokuqala kwaye umgca uxhunyiwe.Emva kokuyikhulula, umgca unqanyuliwe kwaye iqhosha lokuqala Kwaye iqhosha lokumisa likwayinto yokuqhawula okwethutyana kunye nokudibanisa, ngoko uqonde!
3. Fuse
Unokucinga ngayo njenge fuse, kulula ukuyiqonda!
Intshayelelo yomgaqo:
Kulo mzobo, sinokubona i-breaker circuit, i-contactor, amaqhosha amabini, iqhosha lokumisa, kunye neqhosha lokuqala.Ekubeni yi-contactor self-locking circuit, sisebenzisa iqhosha lokuqala.Ekubeni inokuqaliswa, kufuneka imiswe, ngoko sisebenzisa iqhosha lokumisa.Iqhosha livalwa ngesiqhelo.
Amanyathelo ocingo:
Kwi-circuit breaker 2p, umgca we-blue zero ungena kwi-coil yoqhagamshelwano i-A1, umgca ophilayo ungena kwiqhosha elibomvu = iqhosha lokumisa livalwe ngokuqhelekileyo, kwaye umsebenzi umisa isiphaluka.Emva kokuba iqhosha lokumisa livalwe ngokuqhelekileyo, imigca emibini iphuma, kwaye enye ingena kuqhagamshelwano oluncedisayo loqhagamshelwano.Vula HAYI (umfowunelwa u-L1--L2----L3 umfowunelwa okanye umfowunelwa oyintloko uchazwe apha).Ngokusebenzisa i-NO evulekileyo eqhelekileyo yoqhagamshelwano oluncedisayo, ingena kwi-coil A2, kwaye enye ingena kwi-normal open of the start iqhosha, kwaye umsebenzi uqala.Iqhosha lokuqala lihlala livulekile kwaye umgca ophumayo ungena kwi-coil A2 ye-contactor.
Yenza idemo:
Cinezela iqhosha lokuqala i-SB2, i-coil ye-contactor inikwe amandla, ngexesha elifanayo uqhagamshelwano oluphambili lwe-contactor luvaliwe, kwaye uqhagamshelwano oluncedisayo luvaliwe.Umbane oyintloko wombane udlula kwi-fuse kwi-contactor contactor, kwi-relay ye-thermal, ukuya kwisiphaluka, kunye noqhagamshelwano oluncedisayo lwe-contactor luvaliwe.Ngeli xesha, i-contactor inikwe amandla ngenxa yesiphaluka solawulo oluvaliweyo loqhagamshelwano oluncedisayo.
Uhlalutyo lwemigaqo:
Ulawulo lwesiphaluka, ngenxa yokuba isiphaluka solawulo siqhagamshelwe kwi-relay ye-thermal ngokuqhelekileyo ivaliwe, ngoko ke umbane udlula kwi-relay ye-thermal ngokuqhelekileyo ivaliwe i-KM yoqhagamshelwano yokuncedisa, xa sicinezela iqhosha lokuqala, uqhagamshelwano oluncedisayo loqhagamshelwano luvala unikezelo lwamandla ngokusebenzisa contactor umnxeba oncedisayo kwikhoyili yoqhagamshelwano.Ngoko ke i-contactor isoloko inikwe amandla kwaye injini iyaqhubeka isebenza.
