1) Phapang ea meralo ke efe pakeng tsa li-contact tsa DC le AC ho phaella ho coil?
2) Bothata ke bofe haeba matla a AC le motlakase li hokahanya coil ka mocheso o lekantsoeng oa coil ha motlakase le hona joale li tšoana?
Karabo ea Potso ea 1:
Motlakase oa mochine oa DC o batla o le molelele ebile o mosesaane, ha AC contactor coil e khutšoanyane ebile e mafura.Ka hona, khanyetso ea li-coil ea DC e kholo, 'me khanyetso ea coil ea AC e nyenyane.
Li-contactor tsa DC le li-relay tsa DC hangata li sebelisa khoele e habeli, moo khoele ea hona joale e sebelisetsoang ho hula le khoele ea motlakase e sebelisetsoang ho ts'oara.
The AC contactor ke khoele e le 'ngoe.
Mokotla oa tšepe le lihlomo tsa DC contactor ke tšepe eohle e bonolo ea motlakase, 'me sehokelo sa AC ke stack ea sheet sheet ea silicon ho fokotsa tahlehelo ea AC.
The flux in the AC contactor core is alternating and has over zero.At this time, the armature will bounce back under the reaction force, and then hold after zero, kahoo AC contact core e hloka ho hlomelloa le short circuit loop ho felisa. ho sisinyeha ha makenete ka zero.
li-contact le li-coil tsa relay li hlahisa overvoltage ha li lokolloa, li-contact tsa DC le li-relay hangata li felisoa ka li-diode tse ka morao, le li-contact tsa AC le li-relay tse nang le li-circuits tsa RC.
DC contactor arc arc thata, ho bapisa makenete kotlo arc.AC contactor ke batlang e le bonolo ho arc, ho sebelisa C-e bōpehileng joaloka le khoro heke.
Karabo ea Potso ea 2:
The DC contactor coil current e nyane ha motlakase oa DC e le AC e sebetsang hantle.Ka lebaka leo, ha lisebelisoa tse peli tsa motlakase li fetoha, ho ka etsahala hore mochine oa DC o sa kopane, 'me mochine oa AC o chesa hang-hang.
Ho phaella moo, DC contactor hang-hang chesa ka mor'a ho tšehetsa tsoela pele diode ka AC potoloho.
