I-Frame circuit breaker (ACB)

I-Frame circuit breaker ibizwa nangokuthi i-universal circuit breaker.Zonke izingxenye zayo zifakwe ohlakeni lwensimbi oluvalekile, oluvame ukuvuleka.Ingahlonywa izesekeli ezihlukahlukene.Kuyinto elula ukushintsha othintana nabo kanye nezingxenye, futhi isetshenziswa kakhulu ekushintsheni okuyinhloko ekugcineni kwamandla.Kukhona i-electromagnetic, electronic and intelligent over-current release.I-circuit breaker inezigaba ezine zokuvikela: ukubambezeleka isikhathi eside, ukubambezeleka okufushane, iphutha elisheshayo kanye nomhlabathi.Inani lokusetha lesivikelo ngasinye lilungiswa phakathi kobubanzi obuthile ngokuya ngeleveli yegobolondo lalo.
I-breaker circuit yefreyimu iyasebenza kunethiwekhi yokusabalalisa ene-AC 50Hz, i-voltage elinganiselwe engu-380V kanye ne-660V, kanye nesilinganiso samanje esingu-200a-6300a.Ngokuyinhloko isetshenziselwa ukusabalalisa amandla kagesi futhi ivikele imigqa kanye nemishini yokuhlinzeka ngamandla kusukela ekulayisheni ngokweqile, ngaphansi kwe-voltage, i-short circuit, i-single-phase grounding namanye amaphutha.I-circuit breaker inemisebenzi eminingi yokuvikela ehlakaniphile futhi ingafinyelela ukuvikelwa okukhethiwe.Ngaphansi kwezimo ezijwayelekile, ingasetshenziselwa ukushintsha ulayini okungajwayelekile.I-circuit breaker engaphansi kuka-1250A ingasetshenziselwa ukuvikela ukugcwala kanye nesifunda esifushane semoto kunethiwekhi nge-AC 50Hz voltage engu-380V.
I-breaker circuit yohlobo lwefreyimu nayo ivame ukusetshenziswa ekushintsheni okuyinhloko komugqa ophumayo, iswishi yethayi yebhasi, inkinobho enkulu yokuphakela umthamo kanye neswishi yokulawula imoto enkulu ohlangothini lwe-400V lwe-transformer.

I-Yuye yethu yohlaka lwe-circuit breaker ihlanganise wonke ama-currents alinganiselwe, afika ku-6300A, futhi isiphumelele isitifiketi se-CQC.

Imingcele yesici esiyisisekelo se-circuit breaker

(1) I-voltage yokusebenza elinganiselwe i-Ue

I-voltage yokusebenza elinganisiwe ibhekisela ku-voltage yegama le-breaker circuit, engasebenza ngokuqhubekayo ngaphansi kwezimo ezishiwo ezijwayelekile zokusetshenziswa nokusebenza.
I-China ibeka ukuthi amandla kagesi aphezulu okusebenza izikhathi ezingu-1.15 zevolthi elinganiselwe yohlelo ezingeni lika-voltage elingu-220kV nangaphansi;Izinga lika-voltage elingu-330kV nangaphezulu liyizikhathi ezingu-1.1 ze-voltage elinganiselwe njengamandla kagesi aphezulu kakhulu okusebenza.I-circuit breaker ingagcina ukufakwa ngaphansi kwe-voltage ephezulu kakhulu yokusebenza yesistimu, futhi ingenza futhi iphule ngokuvumelana nezimo ezishiwo.

(2) Ikalwe okwamanje (in)

Isilinganiso samanje sisho okwamanje ukukhishwa okungadlula isikhathi eside lapho izinga lokushisa le-ambient lingaphansi kuka-40 ℃.Ku-circuit breaker enokukhululwa okulungisekayo, yizinga eliphezulu lamanje ukukhululwa okungadlula isikhathi eside.
Uma izinga lokushisa le-ambient lidlula ku-40 ℃ kodwa lingekho ngaphezu kuka-60 ℃, kuvunyelwe ukunciphisa umthwalo nokusebenza isikhathi eside.

(3) Inani lamanje lesethingi lokukhishwa kwe-IR

Uma i-current idlula inani lamanje lokusetha i-IR yokukhishwa, i-circuit breaker izolibazisa ukukhubeka.Iphinde imele ubuningi bamanje i-circuit breaker engamelana nayo ngaphandle kokukhubeka.Leli nani kumelwe libe likhulu kunomkhawulo ophezulu wokulayisha wamanje ongu-IB kodwa libe ngaphansi komkhawulo we-iz wamanje ovunyelwe umugqa.
I-IR yokunqanyulwa kokuxhumeka okushisayo ingalungiswa kububanzi obungu-0.7-1.0in, kodwa uma kusetshenziswa okokusebenza kwe-elekthronikhi, ububanzi bokulungisa bukhulu, ngokuvamile bungu-0.4-1.0in.Okwesiphazamisi sesifunda esifakwe ukudluliselwa kohambo lwe-overcurrent okungalungiseki, i-IR = in.

(4) Inani lezilungiselelo zamanje zokukhishwa kwesekethe emfushane im

I-short-circuit tripping relay (ukubambezeleka ngokushesha noma okufushane) isetshenziselwa ukukhuba isinqamuli sesekethe uma kwenzeka iphutha eliphezulu, futhi umkhawulo wayo wokukhubeka uthi im.

(5) Ilinganiselwe ukumelana ne-ICW yamanje

Isho inani lamanje elivunyelwe ukudlula phakathi nesikhathi okuvunyelwene ngaso.Inani lamanje lizodlula kumqhubi phakathi nesikhathi okuvunyelwene ngaso, futhi umqhubi ngeke alimale ngenxa yokushisa ngokweqile.

(6) Ukuphula amandla

Umthamo wokuphuka we-circuit breaker ubhekisela ekhonweni le-breaker circuit ukuze linqamule ngokuphephile i-current yephutha, okungahlobene ngempela nomthamo wayo olinganiselwe.Kukhona 36ka, 50kA kanye neminye imininingwane.Ivamise ukuhlukaniswa ngomthamo we-ICU wokuphuka kwesekethe emfishane kanye nokusebenza kwama-IC wamandla okuphuka isikhashana.
