Isicelo se-Magnetic AC contactor

Okokuqala, izici ezintathu ezinkulu ze-AC contactor:
1. Ikhoyili ye-AC contactor.Ama-Ccoil ngokuvamile ahlonzwa nge-A1 kanye ne-A2, futhi angahlukaniswa kalula abe othintana nabo be-AC kanye nezixhumi ze-DC.Sivame ukusebenzisa othintana nabo be-AC, lapho i-220 / 380V isetshenziswa kakhulu:
2. I-AC Contactor Oxhumana naye oyinhloko.I-L1-L2-L3 ixhunywe kumugqa wokungenisa amandla wezigaba ezintathu, futhi i-T1 T2-T3 ixhunywe kulayini wokuphuma kwamandla, futhi ingasetshenziswa ukuxhuma kulayini 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 boxhumana naye we-AC.Othintwayo abasizayo bangahlukaniswa ngephuzu elivulekile eliqhubekayo CHA kanye nendawo evamise ukuvaleka engu-NC.
I-3-1 Iphuzu elivame ukuvuleka CHA, ngokuvamile iphoyinti elivulekile elithi NO lisetshenziselwa ikakhulukazi isilawuli sokuzikhiya nokudlulisa isignali ukuze isetshenziswe, njengokuthi: I-AC contactor ngokuvamile ivula iphuzu CHA kuya ekukhanyeni okubomvu kungasetshenziswa njengendlela yokusebenza kwemoto. ukukhanya kwenkomba, lapho amandla okuthinta i-AC, ngokuvamile avula iphoyinti CHA ivaliwe, khanyisa isibani senkomba, ukudlulisa isignali yokusebenza kwenjini noma yesekethe.
3-2.Iphoyinti elivamile elivaliwe NC yesixhumi se-AC.Ngokuvamile, i-NC isetshenziselwa ikakhulukazi ukuhlanganisa isifunda 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, engasetshenziswa njengenkomba yokumisa yesekethe noma imoto.Uma isixhumi se-AC sinikwa amandla, indawo yokuvala ehlala njalo i-NC iyanqanyulwa, isibani senkomba yokumisa sicishiwe, ukukhanya kwenkomba yokusebenza okuhambisanayo kuvuliwe, futhi isekethe iyasebenza.
Okwesibili, ngiyaziqonda izimfanelo ezintathu zangaphandle ze-AC contactor, bese sibheka kalula ngaphakathi kwe-AC contactor:
Okokuqala, izingxenye eziyinhloko ze-AC contactor: ikhoyili, i-iron core, intwasahlobo yokusetha kabusha, isistimu yokuxhumana kanye ne-armature nezinye izakhi.
1. Mane uqonde i-armature yesixhumi se-AC.I-armature ixhuma isistimu yokuxhumana, lapho i-armature ihamba phezulu naphansi, indawo yokuxhumana izoshintsha ngokufanele, njengokuthi: ngokuvamile iphuzu elivulekile CHA livaliwe, iphuzu elivame ukuvala i-NC linqanyuliwe nokunye, lokhu ukusetshenziswa okuyisisekelo!
2. Ezinye izakhi ezibalulekile: umnyombo, amakhoyili kanye nokusetha kabusha iziphethu!Ukuqonda kafushane lolu lwazi yilokhu:
Nansi indlela abathintwayo be-AC abasebenza ngayo ngolimi olufinyeleleka kakhulu:
Ngaphambi kokuthi isixhumi se-AC singasebenzi: ikhoyili ayikwazi ukuba ngugesi, ingqikithi ayinawo ukumuncwa kwe-electromagnetic, i-armature ngeke inyakaze, ukunwebeka kwentwasahlobo kuhlala kujwayelekile, kulokhu indawo evame ukuvuleka i-NO icishiwe, indawo evame ukuvalwa i-NC phezu, lesi isimo esijwayelekile.
I-AC contactor kagesi: ikhoyili kagesi, insimbi ikhiqiza ukumuncwa kuka-electromagnetic, inganqoba ukunwebeka kokusetha kabusha kwentwasahlobo, ukudonsa kancane kuhanjiswe phansi, lesi sikhathi uhlelo lokuxhumana luzoshintsha: ngokuvamile iphoyinti elivulekile CHA livaliwe, iphuzu elivame ukuvala i-NC linqanyuliwe, lokhu kuyisisekelo kakhulu. control contactor, contactor kuyinto contact on-off ushintsho ukulawula ngokungaqondile isekethe!
