1) Menene bambancin tsarin tsakanin masu tuntuɓar DC da AC ban da nada?
2) Menene matsalar idan wutar AC da wutar lantarki suna haɗa coil a ma'aunin wutar lantarki na coil lokacin da ƙarfin lantarki da na yanzu sun kasance iri ɗaya?
Amsa ga Tambaya ta 1:
Coil na DC contactor yana da ɗan tsayi tsayi kuma sirara, yayin da AC contactor coil gajere kuma mai ƙiba ne.Saboda haka, juriya na nada na DC yana da girma, juriya na nada AC ƙarami ne.
Masu tuntuɓar DC da relays na DC sukan yi amfani da coil biyu, inda ake amfani da coil ɗin yanzu don tsotsa kuma ana amfani da na'urar wutar lantarki don riƙewa.
Mai tuntuɓar AC coil ɗaya ce.
A baƙin ƙarfe core da armature na DC contactor ne dukan lantarki taushi baƙin ƙarfe, da AC contactor ne silicon karfe takardar tari don rage AC asarar.
A juyi a cikin AC contactor core ne alternating kuma yana da kan sifili.A wannan lokaci, da armature zai billa baya a karkashin dauki karfi, sa'an nan kuma rike bayan sifili, don haka AC lamba core bukatar a sanye take da wani gajeren kewaye madauki don kawar da. Magnetic ta hanyar sifili oscillation.
contactors da gudun ba da sanda coils samar da overvoltage a kan saki, DC contactors da relays gaba daya shafe tare da baya diodes, da AC contactors da relays tare da RC da'irori.
DC contactor lamba baka mai wuya, don daidaita Magnetic hur arc.AC contactor ne in mun gwada da sauki baka, ta amfani da C-dimbin yawa tsarin da baka kofa.
Amsa ga Tambaya ta 2:
The DC contactor nada halin yanzu yana da ƙananan lokacin da DC ƙarfin lantarki ne AC tasiri ƙarfin lantarki.Saboda haka, a lokacin da biyu ikon kayayyakin da aka canza, da DC contactor ne mai yiwuwa ba tsunduma a, da kuma AC contactor ƙone nan da nan.
Bugu da kari, da DC contactor nan da nan ya ƙone bayan goyon bayan ci gaba diode a kan AC kewaye.
