Yintoni umahluko phakathi koqhagamshelwano lwe-AC kunye ne-DC contactor?

1) Uthini umahluko wesakhiwo phakathi kwe-DC kunye ne-AC contactors ngaphezu kwekhoyili?

2) Yintoni ingxaki ukuba i-AC amandla kunye ne-voltage idibanisa i-coil kwi-voltage elinganisiweyo ye-coil xa i-voltage kunye ne-current ifana?

Impendulo kumbuzo 1:

Ikhoyili ye-DC contactor ide kwaye incinci, ngelixa i-coil ye-AC contactor imfutshane kwaye inamafutha.Ngoko ke, ukuxhathisa i-coil ye-coil ye-DC inkulu, kunye nokumelana ne-coil ye-coil ye-AC incinci.

Abafowunelwa be-DC kunye nokuhanjiswa kwe-DC bavame ukusebenzisa i-coil ephindwe kabini, apho i-coil yangoku isetyenziselwa ukufunxa kwaye i-coil ye-voltage isetyenziselwa ukubambelela.

Umnxibelelanisi we-AC yikhoyili enye.

Undoqo wentsimbi kunye nezixhobo zomnxibelelanisi we-DC yintsimbi yonke ethambileyo yombane, kwaye isiqhagamshelanisi se-AC sisitaki se-silicon yentsimbi ukunciphisa ilahleko ye-AC.

I-flux kwi-AC contactor core iyatshintshana kwaye ine-zero.Ngeli xesha, i-armature iya kuphinda ibuyele phantsi kwe-reaction force, kwaye ibambe emva kwe-zero, ngoko ke i-AC yoqhagamshelwano ingundoqo kufuneka ixhotyiswe nge-loop emfutshane yesiphaluka ukuphelisa. imagnethi nge-zero oscillation.

abafowunelwa kunye neekhoyili ezidluliswayo zivelisa ukugqithiswa kwe-overvoltage ekukhululweni, abafowunelwa be-DC kunye neelayidi zipheliswa ngokubanzi ngeediode ezibuyela umva, kunye nee-AC zoqhagamshelwano kunye nokuhanjiswa ngeesekethe zeRC.

DC contactor contact arc nzima, ukudibanisa ukuvuthela magnetic arc.AC contactor kulula noko arc, usebenzisa isakhiwo C-ezimilise kunye nesango arc.

I-DC contactor coil yangoku incinci xa i-voltage ye-DC iyi-voltage esebenzayo ye-AC.Ngoko ke, xa umbane ombini utshintshiwe, i-DC contactor kungenzeka ukuba ayibandakanyekanga, kwaye i-AC contactor ivutha ngokukhawuleza.

Ukongeza, i-DC contactor itshisa ngokukhawuleza emva kwe-diode eqhubekayo exhasayo kwisekethe ye-AC.
