1) Ndeupi musiyano wezvimiro pakati peDC neAC contactors mukuwedzera kune coil?
2) Dambudziko nderei kana simba reAC uye voltage zvakabatanidza coil pachiyero chevoltage yekoiri kana magetsi uye ikozvino zvakafanana?
Mhinduro kumubvunzo wekutanga:
Iyo coil yeDC contactor yakakura uye yakatetepa, nepo AC contactor coil ipfupi uye ine mafuta.Saka, kupikisa kwekoiri yeDC coil yakakura, uye kupikisa kwecoil yeAC coil idiki.
DC macontactor uye DC relays vanowanzo shandisa kaviri coil, uko iyo yazvino coil inoshandiswa kusveta uye iyo voltage coil inoshandiswa pakusveta.
The AC contactor is a single coil.
Iyo simbi musimboti uye armature yeDC contactor ndiyo yese yemagetsi yakapfava simbi, uye iyo AC yekubatanidza ndiyo silicon simbi sheet stack kuderedza kurasikirwa kweAC.
Iyo flux mu AC contactor core iri kuchinjika uye ine pamusoro zero.Panguva ino, armature inodzokera kumashure pasi pesimba rekuita, uye yobva yabata mushure me zero, saka iyo AC yekubatanidza core inoda kuve yakashongedzerwa nepfupi circuit loop kubvisa. iyo magnetic kuburikidza ne zero oscillation.
macontactor uye relay coils anogadzira overvoltage pakuburitswa, DC macontactor uye relays anowanzo kubviswa ne reverse diodes, uye AC macontactor uye relay neRC maseketi.
DC contactor contact arc yakaoma, kuenzanisa magineti blow arc.AC contactor iri nyore kuita arc, uchishandisa C-shaped structure uye arc gedhi.
Mhinduro kumubvunzo wechi2:
The DC contactor coil current idiki kana DC voltage iri AC inoshanda voltage.Saka, kana magetsi maviri achinja, DC contactor inogona kunge isina kubatanidzwa, uye AC contactor inopisa pakarepo.
Mukuwedzera, iyo DC contactor pakarepo inopisa mushure mekutsigira kuenderera mberi diode pane AC circuit.
