Ama-contact ahlukaniswe ama-AC contactor (voltage AC) kanye ne-DC contactors (voltage DC), asetshenziswa emandleni, ekusabalaliseni nasezikhathini zikagesi. Ngomqondo obanzi, othintana naye ubhekisela ezintweni zikagesi zezimboni ezisebenzisa ikhoyili ukugeleza kugesi. yamanje ukukhiqiza inkambu kazibuthe futhi uvale abathintwayo ukuze ulawule umthwalo.
Ku-electrology, ngoba inganqamula ngokushesha i-ac ne-DC main loop futhi ingavula njalo kanye nokulawula kwamanje okuphezulu (kufika ku-800A) isekethe, evame ukusetshenziswa enjinini njengento yokulawula ingasetshenziswa futhi njengejeneretha ye-heater yemishini yokulawula. kanye nomthwalo ohlukahlukene wamandla, i-contactor ayikwazi kuphela ukuvula nokusika isifunda, kodwa futhi ibe nomphumela wokuvikela ukukhululwa kwe-voltage ephansi.Umthamo wokulawula i-Contactor mkhulu, ulungele ukusebenza okuvamile nokulawula okukude, ingenye yezingxenye ezibalulekile ohlelweni lokulawula okuzenzakalelayo. .
Kugesi wezimboni, kunamamodeli amaningi okuxhumana, futhi ukusebenza kwamanje kuyahlukahluka ku-5A-1000A, futhi ukusetshenziswa kwayo kusakazeke kakhulu.
Indlela kasonkontileka iyasebenza
Isimiso sokusebenza se-contactor siwukuthi: lapho ikhoyili ye-contactor inikwa amandla, ikhoyili yamanje izokhiqiza insimu kazibuthe, inkambu kazibuthe yenza umgogodla omile ukhiqize ukumuncwa kwe-electromagnetic ukuheha umgogodla, futhi ishayele isenzo sephuzu le-AC contactor, ngokuvamile kuvale othintana naye. inqanyuliwe, ngokuvamile ivula othintana naye ivaliwe, kokubili kukhona ukuxhumana.Lapho ikhoyili ivaliwe, ukumuncwa kuka-electromagnetic kuyanyamalala, futhi i-armature ikhishwa ngaphansi kwesenzo somthombo wokukhululwa, okwenza othintana naye alulame, ukuthintana okuvame ukuvuleka kuyanqanyulwa, futhi othintana naye ovamise ukuvaleka uyavaleka.Oxhumana nabo be-DC basebenza ngendlela ethi ayifane neshintshi yezinga lokushisa.Indlela yokuhlanganisa izintambo ze-AC
1,3,5 Okokuphakelwa kukagesi wezigaba ezintathu, (ingxenye yesekethe enkulu)
2,4, kanye no-6 Xhuma kumotho enezigaba ezintathu
I-A1, i-A2 amakhoyili we-contactor, exhunywe kumjikelezo wokulawula, kanye ne-motor elawula isekethe (enkulu) ngokulawula ikhoyili ye-contactor (A1, A2).
13,14 Imele ukuthintana okuyisizayo koxhumene naye, futhi CHA ivamise ukuvuleka, okusho ukuthi u-13,14 unqanyuliwe, futhi u-13,14 uvaliwe ngemva kokukhanyisa. , ukufeza inhloso yokusebenza okuqhubekayo.
Okokuqala, othintana nabo bamandla abathathu abakhulu L1, L2, L3 ye-contactor, bese kuba izintambo ezintathu ezivela ku-T1, T2, T3 ye-contactor, ngenhla yisifunda esikhulu.
Umjikelezo wokulawula: kusuka ku-L1 kuholela enkinobho yokumisa uxhumano lwentambo (inkinobho yokumisa ivamise ukuvalwa, inkinobho yokuqala ivame ukuvuleka, lokhu kufanele ukwazi!) omunye umkhawulo wesinye isiphetho se-axiliary contact (le ngxenye iyazikhiya), ikhoyili A1 kanye nekhoyili A2 ixhuma i-L2 noma i-L3.
Okokuqala, siqala ukuqonda ulwazi oluyisisekelo oluningi lwe-Schneider AC contactor lunezinto ezimbili eziyisisekelo, ukuthintana okuyinhloko kanye nekhanda elisizayo, ukuthintana okuyinhloko kusetshenziselwa ukuxhumana nemishini kagesi noma exhunywe kumjikelezo oyinhloko, ukuthintana okusizayo kuxhunywe ekulawuleni. i-circuit, esetshenziselwa ukulawula isifunda esikhulu.
Othintana naye oyinhloko ngokuvamile uxhunywe kumjikelezo oyinhloko, ngokuqondene ne-oda lapho kungekho zidingo ezikhethekile, othintana naye osizayo uxhunywe kumjikelezo wokulawula, ngokuvamile ukukhetha ukuthi ngokuvamile iphoyinti lokuxhumana elivulekile noma iphuzu lokuxhumana elivaliwe ngokuvamile.Lokhu kukhetha kusekelwe ezidingweni zeluphu yokulawula.Ngokuvamile, uma i-AC contactor ivame ukuvuleka futhi othintana nabo abavaliwe abanele, thatha i-Schneider njengesibonelo, inhlangano ingangezwa phezulu.Okufana nokuxhumana okujwayelekile okuvulekile nabavaliwe kuyatholakala ukuze kusetshenziswe.
Ukwahlulela kothintana naye we-AC kuvame ukuvuleka futhi kuvame ukuvala uhla lokushintsha kungasebenzisa ithebula lomhlaba wonke, lapho ukulinganisa kwetafula kwendawo yonke kuzwakala ukufakazela ukuthintana okuvalekile njalo, lapho ithebula lendawo yonke lingazwakali kuvame ukuthintana ovulekile, cindezela insizakalo. inkinobho evame ukuvuleka izokhala, ngokuvamile ivaliwe ngeke ikhale.
