I-AC contactor isetshenziswa kabanzi kusekethe we-low-voltage, iwuhlobo lokusetshenziswa okuphephile, ukulawula okulula, inani elikhulu kanye nezinhlobonhlobo zezidingo zezimboni.I-China manje isetshenziswa ngokujwayelekile ku-40A futhi ngaphezu komthamo omkhulu naphakathi wama-AC contactors kufanele ngaphezu kwamamitha ayizigidi eziyi-100, uhlelo lwayo lwe-electromagnetic olusebenzayo ekumunceni kokusetshenziswa kwamandla okusebenzayo phakathi kuka-8w-100w.Amandla asebenzayo asetshenzisiwe aphakathi kwenqwaba yezikweletu namakhulu ezikweletu.Ukusatshalaliswa kwamandla asebenzayo asetshenzisiwe cishe ku-65%~75% yensimbi core, short circuit ring 25% ~ 30%, 3% ~ 5% ikhoyili.Ngokubuka inkinga yokusetshenziswa kwamandla okukhulu ekusebenzeni kwama-AC contactors, kusukela ngo-1981, idokhumenti yokukhululwa kazwelonke No.I-56 iveze ukuthi izindlela zokonga amandla zabathintana ne-AC kufanele zisetshenziswe.Ngemva kocwaningo lwesikhathi eside, ezinye izimpumelelo zokonga ziye zafinyelelwa, kodwa ukwakheka kwabathintana nabo bendabuko kuye kwaguqulwa kakhulu, inqubo iyinkimbinkimbi, futhi izindleko zokukhiqiza ukwanda.Umkhiqizo oqediwe uyabiza, noma uhla lokusebenzisa luncane, noma aluhambisani nemikhuba yabantu yokusebenzisa, futhi okunye kuthinta nokuthembeka kwawo ngamazinga ahlukahlukene, okungase kube isizathu esiyinhloko esenza ukuthi imikhiqizo yokonga amandla ye-contactor ingazange yamukelwa kabanzi emakethe.
1 Izindlela ezimbalwa ezijwayelekile zokonga amandla zabaxhumani be-AC emakethe kanye nezinzuzo zabo kanye nokubi:
Umgomo wokusebenza wedivaysi esanda kuthuthukiswa yokonga amandla yoxhumene naye
Idivayisi yokonga amandla inomshini wokukhubeka wamahhala, isebenzisa umgomo wokukhiya isixhumanisi se-crank (vula amandla angu-0.15N-0.3N kuphela), umshini ubambeke ngokuqinile, wenze i-electromagnetic contact ingagcina wonke amaqembu oxhumana nabo ngaphandle kokusebenzisa amandla, ivule inhloso ukonga amandla;ngenxa yokuthi iwumshini wokukhiya, impilo yawo angeke ibe phezulu kakhulu, izikhathi ezingaba ngu-35,000, ngakho isetshenziswa ezenzakalweni zokusebenza eziqhubekayo, njengekhabhinethi yesinxephezelo sefeni, iphampu kanye ne-capacitor. Umgomo wokusebenza umi kanje:
Idivayisi yokonga amandla ixhunywe ku-contactor, okuhlanganisa indlu, i-starter rod, indlela yokukhubeka yamahhala, i-micro switch evamise ukuvala, induku, ikhoyili yokonga amandla kanye nokuhlanganisa ibhande logesi. Qala ukuhambisa ngokuthinta isixhumi, usebenzisa i-crank link by umgomo wokukhiya, umshini obambeke ngokuqinile, i-micropower electromagnetic buckle component core suction extrusion micro switch, yenza ukuthintana kwe-micro switch kuvame kuvalwe ukuze kuvame ukuvuleka ukuxhumana, ikhoyili yamandla othintana naye, i-electromagnetic ngaphandle kokusebenzisa amandla isengakwazi ukugcina konke ukusebenza. isimo seqembu lokuxhumana, elikhona kuphela lisuka kukhoyili yokonga amandla lidlule.Lapho isignali yokulawula isetshenziswa ngokuzumayo noma igridi yamandla ihluleka kungazelelwe, ingxenye yokukhubeka ye-electromagnetic ukusetshenziswa kwe-micropower iphusha isixhumanisi ukuze inqamule indlela yamahhala yokukhubeka, futhi isilinganisi esiqalayo siyabuya. endaweni yokuqala ngaphansi kwe-contactor counterforce spring.Ngenxa yokuthi i-micro-power ukusetshenziswa kwe-electromagnetic unbuckle ingxenye edingekayo ukuze uvule amandla amancane kakhulu angenza ukuvula kazibuthe kagesi, ukufeza injongo yokonga amandla.
Umfanekiso 1 wumdwebo wephrofayela wothintana naye noma idivayisi ekhethekile yokonga amandla kanye nesixhumi noma isidluliseli.
I-FIG.2 wumdwebo wokuxhumana kwesekethe wedivayisi ekhethekile yokonga amandla kanye ne-contactor noma i-relay.
3. Izici zedivayisi esanda kwakhiwa ekhethekile yokonga amandla yabathintana nabo
3.1 Akukho ukusetha kabusha okwenziwa ngesandla: igridi yamandla icima ngokuzumayo, isekethe enkulu izonqanyulwa ngokuzenzakalela, ngaphandle kokusetha kabusha mathupha;
3.2 Umsebenzi wokuhlanganisa imishini uqinisekisa ukuphepha nokwethembeka kwemikhiqizo
Idivayisi iphinde ifakwe umsebenzi wokuxhumanisa ngomshini, uma ilokhi ingawuvimbi ngokuqinile umshini, ikhoyili eku-contactor ngeke ivalwe, ukuze othintana naye oyinhloko aqhubeke evaliwe, ngakho-ke uma idivayisi ingakwazi ukusetshenziswa ngokuthembekile. noma ezilimele, ngeke kuthinte ukusetshenziswa okuvamile kwesixhumi soqobo, kodwa umkhiqizo awusawongi amandla.
3.3 Akukho ugesi osizayo odingekayo
Njengoba kuboniswe kuMfanekiso 3, idivayisi yokonga amandla ayidingi ukunikezwa kwamandla asizayo, kanye nesiphakeli samandla esikhulu, futhi ingangeza inkinobho yokumisa ukuze ilawule ukude isixhumi, ngaphandle kwezingozi zokuphepha.
3.4 Xhuma futhi udlale
Idivayisi yokonga amandla ilenga ngokuqondile emikhiqizweni ye-contactor, i-contactor endala noma i-relay ingasetshenziswa ngaphandle kokuguqulwa;ukufakwa okulula, ububanzi bokusetshenziswa.
3.5 Ukusebenza kahle okuphezulu nokonga amandla angaphezu kwama-90%
Uma isetshenziswa nedivayisi, i-AC contact core ayikhiqizi ukumuncwa ngezikhathi ezithile, akukho vibration, ngakho-ke akukho msindo, kunganciphisa kakhulu ukusetshenziswa kwamandla, ukugcinwa okulula, ukunciphisa ngempumelelo izindleko zokusebenza.
3.6 Ungaphazamisi umsebenzi wangempela wokuxhumana noma, kodwa futhi nabanye oxhumana nabo abasizayo abasebenzayo bangengezwa
Ungahlali othintana naye wokuqala wokusiza, kodwa futhi ngokwesidingo, umklamo wokwengeza oxhumana naye osizayo, umsebenzi wokulibaziseka kanye ne-capacitor idivayisi ekhethekile yokonga amandla, ukuze ibe nemisebenzi ehlukene.
3.7 Inganweba umsebenzi kagesi we-anti-sway
Le divayisi inomsebenzi othile wokulibaziseka, ukuxazulula ngempumelelo inkinga "yokunyakazisa ugesi".Okwamanje, ngaphansi kwezimo ezifanayo, impilo yokuxhumana ye-AC contactor yokonga amandla kanye ne-AC contactor yendabuko yanda izikhathi ezingu-3-5, ukunciphisa ukusebenza. kanye nezindleko zokunakekela.
3.8 Ububanzi be-voltage ebanzi
Ukumunca i-voltage ebanzi engu-0.8-1.1US, i-voltage yokukhulula engu-20%~75%US, i-AC-DC yokuxhumana nendawo yonke.
