1. Ikhoyili ye-AC contactor.Cils ivamise ukuhlonzwa nge-A1 kanye ne-A2 futhi ingahlukaniswa kalula izixhumi ze-AC nezixhumi ze-DC.Sivame ukusebenzisa othintana nabo be-AC, lapho i-220 / 380V isetshenziswa kakhulu:
2. Indawo yokuxhumana eyinhloko ye-AC contactor.L1-L2-L3 ixhunywe kulayini wokungenisa amandla wezigaba ezintathu, futhi i-T1 T2-T3 ixhunywe kulayini wokuphuma kwamandla, futhi ingasetshenziswa ukuxhuma umugqa wokulayisha. othintana nabo abakhulu be-AC contactor bavame ukuvuleka othintana nabo, ikakhulukazi abaxhunywe kumjikelezo oyinhloko, ukulawula ukuqala nokuma kwemoto kanye nezinye izinto zokusebenza!
3. Oxhumana nabo abasizayo be-AC contactor.Othintana nabo abasizayo bangahlukaniswa ngephuzu elivulekile eliqhubekayo CHA kanye nephoyinti elivalekile elingu-NC.
3-1 Iphuzu elivame ukuvuleka elithi CHA, ngokuvamile iphoyinti elivulekile elithi CHA lisetshenziselwa ikakhulukazi isilawuli sokuzikhiya nokudlulisa isignali ukuze isetshenziswe, njengokuthi: I-AC contactor ngokuvamile ivula iphuzu CHA kuya ekukhanyeni okubomvu okungasebenza njengenkomba yokusebenza kwemoto. ukukhanya, lapho isixhumi se-AC sinogesi, ngokuvamile iphoyinti elivuliwe CHA livaliwe, khanyisa isibani senkomba, ukudlulisa isignali yokusebenza kwenjini noma yesifunda.
I-3-2, Iphoyinti elivamile elivaliwe i-NC ye-AC contactor.Ngokujwayelekile, i-NC isetshenziselwa ukuxhuma kanye nokudlulisa isignali.
Isibonelo, i-motor positive kanye ne-reverse control circuit isebenzisa umsebenzi wokuxhuma we-contactor evaliwe njalo iphuzu NC.
Isibonelo, i-AC contactor njalo iphoyinti lokuvala i-NC ixhunywe ekukhanyeni kwenkomba eluhlaza, okungasebenza njengenkomba yokumisa yesekethe noma imoto.Uma isixhumi se-AC sisebenza, indawo yokuvala ehlala njalo i-NC iyanqanyulwa, isibani senkomba yokumisa sivaliwe, ukukhanya kwenkomba yokusebenza okuhambisanayo kuvuliwe, futhi isekethe iyasebenza.
Okwesibili, ngiyaziqonda izimfanelo ezintathu zangaphandle ze-AC contactor, bese sibheka kalula ingaphakathi le-AC contactor:
1. Izingxenye eziyinhloko ze-AC contactor: ikhoyili, i-iron core, i-spring yokusetha kabusha, isistimu yokuxhumana kanye ne-armature nezinye izingxenye.
1. Ukuqonda kalula i-armature ye-AC contactor.I-Armature ixhuma isistimu yokuxhumana, lapho i-armature ihamba phezulu naphansi, othintana naye uzoshintsha ngokufanele, njengokuthi: ngokuvamile iphoyinti elivulekile CHA livaliwe, iphuzu elivaliwe ngokuvamile i-NC inqanyuliwe nokunye, lokhu ukusetshenziswa okuyisisekelo!
2. Ezinye izakhi ezibalulekile: umgogodla, ikhoyili, nokusetha kabusha iziphethu!Ukuqonda kafushane lesi sihloko:
Nansi indlela abathintwayo be-AC abasebenza ngayo ngolimi olufinyeleleka kakhulu:
Ngaphambi kokuthi isixhumi se-AC singafakwa ugesi: ikhoyili ayikwazi ukuba kagesi, ingqikithi ayinawo ukumunca i-electromagnetic, i-armature ngeke inyakaze, ukunwebeka kwentwasahlobo kuhlala kujwayelekile, kulokhu kuvame ukuvula iphuzu elithi NO livaliwe, iphuzu elivame ukuvala i-NC ivuliwe, lesi isimo esijwayelekile.
I-AC contactor kagesi: ikhoyili kagesi, ukumuncwa kwe-iron core electromagnetic, kunganqoba ukusetha kabusha kwe-spring elasticity, ukudonsa kancane ukuhambisa phansi, kulokhu, uhlelo lokuxhumana luzoshintsha: ngokuvamile iphoyinti elivulekile CHA livaliwe, iphuzu elivame ukuvalwa i-NC inqanyuliwe, lena yiyona kakhulu. isilawuli esiyisisekelo sothintana naye, othintana naye ngokushintsha kothintana naye ukulawula ngokungaqondile isekethe!
Ngemuva kokuthi isixhumi se-AC siphelelwe amandla noma ukucisha amandla, ikhoyili ngeke ibe kagesi, ingqikithi ayinawo ukumunca kazibuthe kagesi, ngalesi sikhathi, ukunwebeka kokusetha kabusha kwentwasahlobo kushayela ukusetha kabusha kwe-armature, i-armature bounce, ngalesi sikhathi, idrayivu ye-armature. isistimu yokuxhumana ye-AC contactor ukuhambisa, ukubuyisela esimweni sokuqala: iphuzu elivame ukuvuleka CHA linqanyuliwe, iphuzu elivame ukuvalwa i-NC livaliwe.
