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 lukagesi olusebenzayo ekumunceni kokusetshenziswa kwamandla okusebenzayo phakathi kuka-8w-100w. Amandla asebenzayo asetshenzisiwe aphakathi kwenqwaba yezikweletu namakhulu Izikweletu.Ukusatshalaliswa kwamandla asebenzayo asetshenzisiwe cishe kungu-65%~75% we-iron core, i-short circuit ring 25%~30%, 3% ~ 5% ikhoyili.Ngokubuka inkinga yokusetshenziswa kwamandla okukhulu ekusebenzeni kwezixhumi ze-AC, kusukela ngo-1981, idokhumenti kazwelonke yokukhululwa 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, kanti okunye kuthinta nokuthembeka kwawo ngamazinga ahlukahlukene, okungase kube yisizathu esikhulu esenza imikhiqizo yokonga amandla othintana naye ayamukelwanga 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 isimiso sokukhiya, umshini obambeke waqina, 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, uzibuthe kagesi ngaphandle kokusebenzisa amandla usengakwazi ukugcina sonke isimo sokusebenza seqembu lokuxhumana, elisebenza kuphela ukusuka kukhoyili yokonga amandla. ingxenye yokukhubeka iphusha isixhumanisi ukuze inqamule indlela yamahhala yokukhubeka, futhi isilinganisi esiqala sibuyela endaweni lapho siqala khona ngaphansi kwe-contactor counterforce spring.Ngenxa yokuthi ukusetshenziswa kwamandla amancane kwe-electromagnetic unbuckle ingxenye edingekayo ukuze Ukuvula amandla amancane kakhulu kungenza ukuvula kazibuthe, ukufeza inhloso 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 Dlala
Idivayisi yokonga amandla ilenga ngokuqondile emikhiqizweni ye-contactor, i-contactor endala noma i-relay ingasetshenziswa ngaphandle kokuguqulwa; ukufakwa okulula, ububanzi bokusebenzisa.
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.
