Na farko, manyan halaye guda uku na mai tuntuɓar AC:
1. AC contactor nada.Coils yawanci A1 da A2 suna gano su, kuma ana iya raba su zuwa masu tuntuɓar AC da masu tuntuɓar DC.Sau da yawa muna amfani da masu tuntuɓar AC, wanda 220/380V shine mafi yawan amfani da su:
2. AC Contactor Babban lamba.L1-L2-L3 an haɗa shi zuwa layin mashigai na wutar lantarki mai hawa uku, kuma T1 T2-T3 yana haɗa da layin samar da wutar lantarki, kuma ana iya amfani dashi don haɗawa da layin kaya.Babban lambobin sadarwa na AC contactor sau da yawa bude lambobin sadarwa, akasari an haɗa su zuwa babban kewayawa, don sarrafa farawa da tsayawa na motar da sauran kayan aiki!
3. Lambobin taimako na mai tuntuɓar AC.Za'a iya raba abokan haɗin gwiwar zuwa madaidaicin buɗaɗɗen ma'auni NO da madaidaicin rufaffiyar 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 za a iya amfani da matsayin motor aiki. Hasken mai nuna alama, lokacin da wutar mai tuntuɓar AC, sau da yawa buɗaɗɗen wuri NO a rufe, kunna hasken mai nuna alama, don watsa siginar aiki ko motsi.
3-2.Ma'anar rufewa ta al'ada NC na mai tuntuɓar AC.Gabaɗaya, ana amfani da NC galibi don haɗawa da kewayawa da watsa sigina.
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 za a iya amfani da 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 kewayawa yana gudana.
Na biyu, na fahimci halaye guda uku na waje na AC contactor, sa'an nan kuma duba cikin sauki a cikin AC contactor:
Na farko, manyan abubuwan da aka haɗa na AC contactor: nada, baƙin ƙarfe core, sake saiti spring, lamba tsarin da armature da sauran aka gyara kunshi.
1. Kawai fahimtar armature na AC contactor.Armature yana haɗa tsarin tuntuɓar, lokacin da armature ya motsa sama da ƙasa, wurin tuntuɓar zai canza daidai, kamar: sau da yawa buɗaɗɗen wurin NO rufe, sau da yawa rufe madaidaicin NC da sauransu, wannan shine ainihin amfani!
2. Sauran mahimman abubuwan haɗin gwiwa: core, coils da sake saita maɓuɓɓugan ruwa!A takaice fahimtar wannan bayanin shine:
Ga yadda masu tuntuɓar AC ke aiki a cikin yaren da ya fi dacewa:
Kafin AC contactor ba a powered: 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 lokacin da sau da yawa bude batu NO ne a kashe, da sau da yawa rufe batu NC ne. akan, wannan shine yanayin al'ada.
AC contactor lantarki: nada wutar lantarki, baƙin ƙarfe core samar electromagnetic tsotsa, iya shawo kan sake saiti spring elasticity, ja da bit koma ƙasa, wannan lokaci lamba tsarin zai canza: sau da yawa bude batu NO rufe, sau da yawa rufe batu NC katse, wannan shi ne mafi asali. contactor iko, contactor ne ta lamba on-kashe canji don sarrafa da'irar a kaikaice!
