Umgomo we-AC contactor ukuthi amandla adonswa ngaphakathi, othintana naye oyinhloko uvaliwe futhi uvule, futhi injini igijima.Lesi sihloko sethula isifunda sokuzikhiya se-AC contactor futhi kuyini ukuzivala kwe-contactor
1. Inkinobho yokumisa
Izintambo zenkinobho yokumisa kufanele zixhunywe koxhumana naye ovamise ukuvaleka.Yini evamise ukuvalwa?Ungakuqonda ngale ndlela, uma singacindezeli inkinobho yokumisa, inkinobho yokumisa ihlezi ivuliwe, cindezela inkinobho yokumisa ukuze unqamule, futhi ukhulule inkinobho yokumisa, isaxhumekile, ngakho kulula ukuyiqonda!
2. Inkinobho yokuqala
Inkinobho yokuqala kufanele ixhunywe koxhumana naye ovame ukuvuleka.Ungakwazi futhi ukuqonda okuvamise ukuvulwa njengenkinobho yokumisa.Inkinobho yokuqala ihlale inqanyuliwe uma singacindezeli inkinobho yokuqala.Cindezela inkinobho yokuqala futhi umugqa uxhunyiwe.Ngemva kokuwukhulula, umugqa unqanyuliwe kanye nenkinobho yokuqala Futhi inkinobho yokumisa iphinde ibe ukunqanyulwa kwesikhashana nokuxhumeka, ngakho-ke qonda!
3. I-Fuse
Ungacabanga ngakho njenge-fuse, kulula ukuyiqonda!
Isethulo sesimiso:
Emfanekisweni, singabona i-circuit breaker, i-contactor, izinkinobho ezimbili, inkinobho yokumisa, nenkinobho yokuqala.Njengoba kuyisiyingi sokuzikhiya se-contact, sisebenzisa inkinobho yokuqala.Njengoba ingaqalwa, kufanele imiswe, ngakho sisebenzisa inkinobho yokumisa.Inkinobho ivamise ukuvalwa.
Izinyathelo zokufaka izintambo:
Ku-circuit breaker 2p, ulayini we-zero oluhlaza okwesibhakabhaka ungena kukhoyili yokuxhumana ethi A1, umugqa obukhoma ufaka inkinobho ebomvu = inkinobho yokumisa ivamise ukuvalwa, futhi umsebenzi umisa isekethe.Ngemva kokuthi inkinobho yokumisa kuvame ukuvalwa, imigqa emibili iyaphuma, futhi eyodwa ingena koxhumana naye osizayo.Vula CHA (othintana naye L1--L2---L3 othintana naye noma othintana naye oyinhloko uchazwe lapha).Nge-NO evame ukuvuleka yokuxhumana nomsizi, ingena kukhoyili A2, futhi enye ingene ekuvuleni ngokuvamile kwenkinobho yokuqalisa, bese umsebenzi uqala.Inkinobho yokuqala ivamise ukuvuleka bese ulayini ophumayo ungena kukhoyili A2 yesixhumi.
Qalisa idemo:
Cindezela inkinobho yokuqala SB2, ikhoyili yokuxhumana inikwa amandla, ngesikhathi esifanayo othintana naye omkhulu uvaliwe, futhi oxhumana naye osizayo uvaliwe.Ukunikezwa kwamandla kalayini oyinhloko kudlula i-fuse kothintana naye othintana naye, ku-relay eshisayo, kumjikelezo, futhi ukuthintana okusizayo koxhumana naye kuvaliwe.Ngalesi sikhathi, i-contactor inikezwe amandla ngenxa yesifunda sokulawula esivaliwe soxhumana naye osizayo.
Ukuhlaziya izimiso:
Isifunda sokulawula, ngoba isifunda sokulawula sixhunywe kusilayidi esishisayo esivame ukuvaleka, ngakho-ke amandla kagesi adlula endaweni edluliselwe ezishisayo evamise ukuvala othintana naye osizayo we-KM, lapho sicindezela inkinobho yokuqala, othintana naye osizayo uvala ugesi ngokusebenzisa othintana naye noma osizayo kukhoyili yokuxhumana.Ngakho-ke i-contactor ihlale inikwe amandla futhi injini iyaqhubeka nokusebenza.
