1. A AC contactor coil.Cils yawanci gano da A1 da A2 kuma za a iya kawai raba AC contactors da DC contactors.Sau da yawa muna amfani da masu tuntuɓar AC, wanda 220/380V shine mafi yawan amfani da su:
2. Main lamba batu na AC contactor.L1-L2-L3 an haɗa zuwa uku-lokaci iko mashiga line, da kuma T1 T2-T3 an haɗa zuwa ikon kanti line, kuma za a iya amfani da su haɗa da load line. manyan lambobi na AC contactor sau da yawa bude lambobin sadarwa, akasari an haɗa zuwa babban da'irar, don sarrafa farawa da tsayawa na mota da sauran kayan aiki!
3. Auxiliary lambobin sadarwa na AC contactor.The karin lambobin sadarwa za a iya raba zuwa m bude batu NO da kullum rufe batu NC.
3-1 Sau da yawa bude batu NO, yawanci sau da yawa bude batu NO ne yafi amfani da contactor kai-kulle iko da canja wurin siginar aiki don amfani, kamar: AC contactor sau da yawa bude batu NO zuwa ja nuna haske iya aiki a matsayin motor aiki nuna alama. haske, lokacin da mai tuntuɓar AC yana da wutar lantarki, sau da yawa buɗaɗɗen wuri NO a rufe, kunna fitilar mai nuna alama, don watsa siginar aiki ko motsi.
3-2, Al'ada rufaffiyar batu NC na AC contactor.Generally, da NC da ake amfani da interlocking da sigina watsa.
Alal misali, da mota tabbatacce da kuma baya kula da kewaye yana amfani da interlocking aiki na contactor akai rufaffiyar batu NC.
Misali, AC contactor akai-akai rufe batu NC an haɗa zuwa kore nuna alama haske, wanda zai iya zama a matsayin tasha nuna alama na kewaye ko mota.Lokacin da aka kunna mai tuntuɓar AC, madaidaicin madaidaicin madaidaicin NC ya katse, hasken mai nuna alamar tsayawa yana kashe, hasken aikin da ya dace yana kunne, kuma kewaye yana gudana.
Na biyu, na fahimci halaye guda uku na waje na mai tuntuɓar AC, sannan in yi dubi cikin sauƙi ga cikin mai tuntuɓar AC:
1. Babban abubuwan da aka haɗa na AC contactor: coil, iron core, reset spring, lamba tsarin da armature da sauran aka gyara.
1. Kawai fahimtar armature na AC contactor.Armature yana haɗa tsarin tuntuɓar, lokacin da armature yana motsawa sama da ƙasa, lambar sadarwa za ta canza daidai, kamar: sau da yawa buɗaɗɗen batu NO rufe, sau da yawa rufe batu NC da sauransu, wannan. shine ainihin amfani!
2. Sauran muhimman abubuwan da suka shafi: core, coil, and reset springs!Taƙaitaccen fahimtar wannan labarin shine:
Ga yadda masu tuntuɓar AC ke aiki a cikin yaren da ya fi dacewa:
Kafin AC contactor ba a electrified: nada ba zai iya zama lantarki, da core ba shi da wani electromagnetic tsotsa, da armature ba zai motsa, da spring elasticity zauna al'ada, wannan lokaci sau da yawa bude batu NO ne a kashe, sau da yawa rufe batu NC ne a kunne. wannan shi ne yanayin al'ada.
AC contactor lantarki: nada lantarki, baƙin ƙarfe core electromagnetic tsotsa, iya shawo kan sake saiti spring elasticity, ja da bit matsawa ƙasa, wannan lokaci, da lamba tsarin zai canza: sau da yawa bude batu NO rufe, sau da yawa rufe batu NC katse, wannan shi ne mafi. na asali contactor iko, contactor ne ta lamba canji don sarrafa da'irar a kaikaice!
Bayan mai tuntuɓar AC ɗin ya rasa wuta ko kashe wutar lantarki, nada ba zai zama lantarki ba, ainihin ba shi da tsotsawar electromagnetic, a wannan lokacin, elasticity na sake saitin bazara yana tafiyar da sake saitin armature, billa armature, a wannan lokacin, armature yana motsawa. tsarin tuntuɓar mai tuntuɓar AC don motsawa, mayar da shi zuwa yanayin farko: sau da yawa buɗaɗɗen batu NO katse, sau da yawa rufaffiyar batu NC ya rufe.
