Xhumana nomgomo wabaxhumi be-AC.
Lapho ikhoyili ixhunyiwe, umgogodla wensimbi we-static transformer ubangela amandla e-eddy adsorption wamanje ukuthi agaye futhi amunce inkaba yensimbi ye-dynamic transformer.Ngenxa yokuthi isofthiwe yesistimu yephoyinti lokuxhumana ixhunywe nomgogodla wensimbi ye-transformer ehambayo, umgogodla we-iron transformer onyakazayo uphusha amaphuzu amathathu okuxhumana ahambayo ngesikhathi esisodwa, othintana naye oyinhloko uyavala, usize ukuthintana okuvamise ukuvaleka ukuthi kuphuke, isiza iphuzu elivame ukuvaleka ukuze vala, bese uxhuma ugesi wokushintsha.
Lapho ikhoyili icishiwe, amandla e-adsorption ayadamba, futhi ingxenye exhumayo yomgogodla we-iron we-transformer enyakazayo ihlukaniswa amandla okubuyela emuva kwe-torsion spring, iphula i-breaker circuit main, kanye nokuxhumana okuvamisile okuvamise ukuvala okuxhunywe Umkhono wephoyinti lokuxhumana eliyinhloko uvaliwe ukusiza oxhumana naye ovamile ovaliwe.Iphoyinti lokuvala liphukile, futhi ukunikezwa kwamandla okushintshwa kuyanqanyulwa.
I-contactor yokuxhumana isetshenziswa kuphela ukuxhumana nomzila wokuxhumana.Uma isixhumi se-AC kufanele sixhunywe ku-DC, isiphetho kufanele kube ukuthi umzila ngisho nemishini nemishini konakele kakhulu.
Ingxenye ebalulekile yesixhumi sokuxhumana.
(1) Isofthiwe yohlelo lokungeniswa kwe-electromagnetic, okuhlanganisa amakhoyili ahehayo, insimbi ye-transformer ehambayo kanye nezinhlayiya zensimbi ezimile;
(2) Isofthiwe yesistimu ye-circuit breaker ihlanganisa amaqembu amathathu ama-breaker circuit main kanye neqembu elilodwa kuya kwamabili okuvula nokuvala.I-auxiliary circuit breaker evamile evaliwe ixhunywe kumgogodla wensimbi we-transformer ehambayo;
(3) Izinto ezifutha kazibuthe, izixhumi ze-AC ezinomthamo omkhulu ngokuvamile zifakelwe okokusebenza kazibuthe, okulungele ukunqamula ngokushesha ukuhlukaniswa kukagesi futhi kuvimbele ukushiswa kwe-breaker circuit;
(4) Ibhokisi lebhokisi le-insulation layer kanye nezinsiza, iziphethu ezihlukahlukene, izindlela zokudlulisela, izindandatho zamaphutha e-short-circuit, amatheminali, njll.
Xhumana nendlela yezintambo yesixhumi se-AC.
Kukhona i-logo ku-contactor (ngokusekelwe eqinisweni)
I-1L3L5L, ehambisana ne-2T4T6T, iyisixhumi esibonakalayo esibalulekile.
Amakhoyili ahambisanayo anamatheminali A1A2.
Oxhumana nabo abasizayo bangafaniswa.
13.14 ikhombisa ukuthintana okuyisizayo koxhumene naye, CHA ikhombisa ukuvuleka nokucisha, okungukuthi, i-13.14 inqanyuliwe ngaphandle kokuxhuma, futhi i-13.14 ivaliwe ngemva kokuxhuma. yeluphu yokulawula ukuze kuzuzwe injongo yokusebenza okuqhubekayo.
Ukuxhumana kwe-AC contactor umdwebo wezintambo.
Lungisa iluphu yokulawula ukusebenza okubuyisela emuva.
1. Hlola ukuthi izintambo zesekethe enkulu zilungile yini.Ukuze kuqinisekiswe ukuthi oxhumana nabo ababili bangakwazi ukufaka esikhundleni ngokuthembekile intambo ephilayo engathathi hlangothi yemoto lapho besuswa, izintambo zangaphandle ze-contactor kufanele zihambisane futhi zilungiswe emgodini ophansi we-contactor.
2. Ngemuva kokuhlola ukuthi i-wiring ilungile, ukuhlolwa kwe-plug-in kufanele kwenziwe.Ukuze ugweme ukulimala, nqamula izintambo zenjini kuqala.Ukulungiselela izimo zephutha elivamile;
1. Akukho ukusebenza;esinye sezizathu ukuhlola ukuthi umshwalense wezohwebo i-FU unomjikelezo omfushane, ukuthi isixhumi se-FR se-thermal relay sisetshenziswa ngokungalungile noma sinokuthintana okungekuhle, nokuthi isixhumi esivalekile senkinobho ye-SB1 asilungile yini.Isici sesibili izintambo ezingalungile zokhiye ozikhiyayo ozikhiyayo.
2. Ngesikhathi sokusebenza, i-contactor ayimunyi;lokhu kungenxa yokuthi othintana naye ovamise ukuvaleka we-contactor uxhumeke ngokungalungile ku-interlock yokuzikhiya, futhi ukuthinta okuzivalelayo nokuzingenelayo kuzikhiyela.Lapho isebenza, indawo yokuxhumana evamise ukuvaleka isixhumi sikagesi sokumunca ikhoyili yekhoyili.Ngemva kokuba ikhoyili ye-contactor icishiwe, ikhoyili ye-contactor iyayekwa amandla futhi ikhululwe, isixhumi esivamise ukuvaleka siyakhululwa, isixhumi simuncwa futhi, bese kuthi esixhumene naye sinqanyulwe futhi.Ngakho-ke, i-contactor ayidonswa kalula.
3. Isixhumi esizikhiyayo asikwazi ukunqanyulwa.Lokhu kubangelwa i-wiring engalungile yokuxhumana okuzikhiya kanye nokusebenza okubuyisela emuva kwe-motor.Ukuze unike amandla kangcono injini ukuthi ijikelezise phambili futhi ihlehle, izixhumi ezimbili ze-KM1.KM2 motor ezintathu Isigaba samandla esiphakeli sentambo engathathi hlangothi intambo ephilayo, kodwa izixhumi ezimbili azikwazi ukugayeka nokumuncwa.Uma kugaywe futhi kumuncwa ngesikhathi esifanayo, kuzodala ingozi yokuphepha kwesekethe efushane kagesi.Ukuze ugweme izingozi zokuphepha, isifunda sokuphakela amandla kufanele sisebenzise i-interlock ethembekile yokuzikhiya.
I-anatomy yomzila ibukeka kanje:
1. Ukugijima ngendlela eqondile:
1. Cisha inkinobho yokuvuza komoya i-QF bese uxhuma ugesi wezigaba ezintathu.
2. Cindezela bese ubamba inkinobho yokuya phambili ethi SB3, i-KM1 ixhunyiwe, idonswe ngaphakathi futhi izikhiya, futhi i-circuit breaker eyinhloko ivaliwe futhi ivaliwe ukuze kuxhunywe injini.Ngalesi sikhathi, ucingo olungathathi hlangothi lwe-motor luyi-L1.L2.L3, okungukuthi, lusebenza ngendlela enhle.
2. Ukugijima kwelinye icala:
1. Cisha inkinobho yokuvuza komoya i-QF bese uxhuma ugesi wezigaba ezintathu.
2. Cindezela bese ubamba inkinobho yokusebenza ethi SB2 iye kolunye uhlangothi, i-KM2 iyazivala ngokuya kothintana naye oyisizayo, ivamise ukucisha othintana naye oyinhloko, bese ibuyisela ucingo olungathathi hlangothi kanye nocingo olubukhoma lwezigaba ezintathu zamandla kagesi. .Ngalesi sikhathi, umugqa we-zero we-motor L3.L2.L1, okungukuthi, usebenza ngokuphambene.
3. Isiteji sokuzikhiya nesokuhlangana: Sinomsebenzi owenqatshelwe ngokuphelele futhi sinomphumela wokuqinisekisa ukuphepha emugqeni wokusabalalisa.
