Inqubo kanye nendlela yokuhlola uhambo kanye nokwehluleka ukuvala kabusha kwe-air circuit breaker(ACB)

I-air circuit breaker(I-ACB) ukukhubeka, ukuvala kabusha kwehlulekile

1. Okokuqala thola ukuthi iI-air circuit breakerayikhubeki ngephutha

Uhambo olungelona lwengozi lusho uhambo olungenawo umjikelezo omfushane noma iphutha lokugcwala kakhulu.Kunezizathu eziningi zalokhuI-air circuit breakerhhayi ukuvala.Okokuqala, kuyadingeka ukunquma uhambo olubangelwa ukujikeleza okufushane nokugcwala ngokweqile, noma ii-air circuit breakerngokwayo noma iluphu yokulawula inephutha.Thola futhi unqume ukuthi isekethe inephutha noma i-i-air breakeryona ngokwayo inephutha.
Ngemuva kokunquma iphutha le-air circuit breaker, khipha i-circuit breaker (ibhekisela ku-i-drawer yohlobo lwe-air circuit breaker) ukuze zihlolwe.

2. I-Universal Type circuit breaker ukulungisa izinkinga ezivamile

(1) I-breaker circuit ayikwazi ukuvalwa ngenxa yokuphelelwa amandla kudivayisi yokukhubeka engaphansi kwe-voltage.Uma i-voltage iphansi kakhulu noma ikhoyili ye-undervoltage tripping device iphelelwe amandla, i-circuit breaker izokhubeka futhi ayikwazi ukuphinda ivalwe.Lezi zimo ezine ezilandelayo zingenza ikhoyili ye-undervoltage tripper iphelelwe amandla.

• (1) I-fuse yesekethe yokuvikela ishaywa umoya, njenge-RT14, okuholela ekuvinjweni kwesekethe kanye nokuphelelwa amandla ekhoyili ekhubekayo yedivayisi yokukhubeka engaphansi kwamandla;
• (2) Inkinobho yokuvala, ukuthintana kwe-relay, i-circuit breaker yokuxhumana nomsizi wekhanda ukuthintana okubi, ukonakala kwengxenye, kungaholela ekuvinjweni kwesekethe, ukukhubeka kukagesi ikhoyili;
• (3) Intambo yokuxhuma ku-loop iphukile, futhi isikulufu se-crimping sikhululekile futhi sikhululekile, okuzophinde kuholele ekutheni isekethe ivinjwe, futhi ikhoyili ekhubekayo inqanyuliwe;
• (4) Ngenxa yokuthi ikhoyili yokukhishwa kwe-undervoltage isesimweni sokusebenza kukagesi isikhathi eside, ukungcoliswa kwemvelo nezikhali akuguquguquki, noma igebe lomoya phakathi komgogodla ne-armature likhulu kakhulu, kulula yenza i-current ibe nkulu kakhulu futhi iholele ekushiseni nasekushiseni kwekhoyili, ilahlekelwe umsebenzi wekhoyili yokukhulula.
• Iphutha elingenhla ngokubheka kanye nokuhlola okulula nokuhlola kungenza isinqumo esifanele, ngakho-ke uma iphutha litholakele kufanele liqedwe ngesikhathi, njengokuthintana okuxekethile ukuze kuqiniswe, ukulimala kwezingxenye kanye nokushiswa kwamakhoyili okudingeka kushintshwe.

(2) Ukuhluleka kwesistimu yemishini, okuholela ekutheni i-circuit breaker ayikwazi ukuvala.Ngemva kokukhubeka nokuvala indlela yokusebenza ye-circuit breaker izikhathi eziningi, umshini ugqokwa kakhulu futhi amaphutha alandelayo angase avele.

• (1) Ukuguga kwemishini yokuhambisa imoto, njenge-ME switch worm gear, ukulimala kwezikelemu, akukwazi ukushayela ibhande lendlela yokusebenza ye-circuit breaker, vala.Igiya lezikelemu, ukushintshwa kwezikelemu kuyinkimbinkimbi kakhulu, isidingo sokulondolozwa kochwepheshe.
• (2) ukuguga kwamahhala kwemishini yokukhubeka, ukuze isinqamuli sesifunda sibe nzima ukusibopha, sikhubeke kalula, kwesinye isikhathi siphoqwe ukuba sibophe, uma kwenzeka ukudlidliza, uhambo;Ngezinye izikhathi ngemva kwebhande, ibhande elivaliwe lizoshelela.Ngalesi sikhathi, isikulufu sokulungisa kufanele sijikelezwe ukuze kulungiswe indawo ehlobene yokukhubeka kwe-half shaft kanye nebhande elikhubekayo, ukuze indawo yokuxhumana ibe ngu-2.5mm2, futhi izingxenye ezihambisanayo kufanele zishintshwe uma kunesidingo.
• (3)Isiphethu sokugcina amandla sendlela yokusebenza sinephutha.Isiphethu sokugcina amandla esiphukayo sendlela yokusebenza siyaxegisa noma silahlekelwe ukunwebeka ngemva kokunwebeka okuningi, futhi amandla okuvala abe mancane.Lapho uvala, indlela ye-4-bar ye-circuit breaker ayikwazi ukuphushwa endaweni yephuzu elifile, futhi umshini awukwazi ukuzigcina usendaweni yokuvala.Ngakho-ke, i-breaker circuit ayikwazi ukuvalwa ngokujwayelekile.Isiphethu sokugcina kufanele sishintshwe.
• (4)Indlela yokusebenza ayiguquki, futhi kukhona into ebambekile.Ngenxa yokuthi lolu hlobo lwe-circuit breaker aluvalwanga ngokugcwele, uma izikulufi, amantongomane nezinye imizimba yangaphandle zishiywe ngephutha endleleni yokusebenza, ukuze umsebenzi we-circuit breaker ubambezeleke, kuzothinta ukuvala;Ngaphezu kwalokho, ukujikeleza kanye nezingxenye ezishelelayo azinawo amafutha okugcoba, indawo yokugcina amandla yokuvula indlela yokusebenza ikhubazekile kancane, futhi i-breaker circuit ayikwazi ukuvala ibhuleki.Ngakho-ke, lapho ukwehluleka okungenhla kwenzeka, ngaphezu kokuhlola indlela yokusebenza, akukho mehluko, kodwa futhi ukujova igrisi yokugcoba engxenyeni yokujikeleza kanye ne-sliding.
