Isixhumi se-AC kanye nesixhumi se-DC

1) Uyini umehluko wesakhiwo phakathi kwe-DC kanye ne-AC contactors ngaphezu kwekhoyili?

2) Iyini inkinga uma amandla kagesi kanye ne-voltage ye-AC kuxhuma ikhoyili ku-voltage elinganiselwe yekhoyili lapho i-voltage ne-current kufana?

Impendulo yombuzo 1:

Ikhoyili ye-DC contactor yinde futhi izacile, kuyilapho ikhoyili ye-AC contactor imfushane futhi namafutha.Ngakho-ke, ukumelana nekhoyili yekhoyili ye-DC kukhulu, futhi ukumelana kwekhoyili kwekhoyili ye-AC kuncane.

Ama-DC contactor kanye nama-DC relay avame ukusebenzisa ikhoyili ekabili, lapho ikhoyili yamanje isetshenziselwa ukumunca futhi ikhoyili ye-voltage isetshenziselwa ukubamba.

Isixhumi se-AC ikhoyili eyodwa.

I-iron core kanye ne-armature ye-DC contactor iyonke insimbi ethambile kagesi, futhi isixhumi se-AC siyisitaki seshidi le-silicon ukuze kwehliswe ukulahleka kwe-AC.

I-flux ku-AC contactor core iyashintshana futhi inoziro. Ngalesi sikhathi, i-armature izobuyela emuva ngaphansi kwamandla okusabela, bese ibamba ngemva kukaziro, ngakho-ke i-AC contact core idinga ukuhlonyiswa ngeluphu yesekethe emfushane ukuze iqedwe. i-magnetic ngokusebenzisa i-zero oscillation.

othintana nabo namakhoyili adluliselwe akhiqiza ukugcwala ngokweqile lapho ekhululwa, oxhumana nabo be-DC namarelayidi ngokuvamile asuswa ngama-diode ahlehlayo, nezixhumi ze-AC kanye namasekhethi e-RC.

I-DC contactor arc arc kunzima, ukufanisa magnetic blow arc.AC contactor kulula uma kuqhathaniswa ne-arc, kusetshenziswa isakhiwo esimise okwe-C nesango le-arc.

Ikhoyili yekhoyili ye-DC incane uma amandla kagesi e-DC kuyi-voltage esebenzayo ye-AC.Ngakho-ke, lapho izinto ezimbili zikagesi zishintshwa, isixhumi esithinta i-DC cishe asibandakanyiwe, futhi isixhumi se-AC siyasha ngokushesha.

Ngaphezu kwalokho, i-DC contactor iyasha ngokushesha ngemva kwe-diode eqhubekayo esekela kusekethe ye-AC.
