Izici Ezisebenzayo Zezinhlobo Ezihlukene Zabalawuli Abahlakaniphile
Uhlobo lwe-M: Ngokungeziwe kuzici zokuvikela zezigaba ezine zokulibaziseka kokulayishwa kakhulu isikhathi eside, ukubambezeleka kwesikhathi esifushane kwesekethe, ukuvuza ngokushesha nomhlaba, futhi inenkomba yesimo sephutha, irekhodi lephutha, umsebenzi wokuhlola, isibonisi se-ammeter, isibonisi se-voltmeter, isignali ye-alamu ehlukahlukene. okukhiphayo, njll Inohlu olubanzi lwamanani endawo yesici sokuvikela kanye nemisebenzi ephelele eyisiza.Kuwuhlobo olunemisebenzi eminingi futhi lungasetshenziswa ezinhlelweni eziningi zezimboni ezinezidingo eziphezulu.
H uhlobo: Ingaba nayo yonke imisebenzi yohlobo lwe-M.Ngesikhathi esifanayo, lolu hlobo lwesilawuli lungakwazi ukubona imisebenzi "emine eyirimothi" ye-telemetry, ukulungiswa kwerimothi, isilawuli kude kanye nokusayina okukude ngekhadi lenethiwekhi noma isiguquli esibonakalayo.Ilungele uhlelo lwenethiwekhi futhi ingagadwa phakathi nendawo futhi ilawulwe yikhompyutha ephezulu.
1. Umsebenzi we-ammeter
I-current of the main circuit ingaboniswa esikrinini sokubonisa.Uma ukhiye wokukhetha ucindezelwa, umthamo wamanje wesigaba lapho isibani senkomba sitholakala khona noma isigaba esiphezulu samanje sizoboniswa.Uma ukhiye wokukhetha ucindezelwa futhi, i-current yesinye isigaba izovezwa.
2. Umsebenzi wokuzihlola
◇ Iyunithi yohambo inomsebenzi ◇ wokuxilongwa kwamaphutha wendawo.Uma ikhompuyutha iphuka, ingathumela iphutha elithi “E” isibonisi noma i-alamu, bese iqalisa kabusha ikhompuyutha ngesikhathi esifanayo, umsebenzisi futhi anganqamula i-circuit breaker uma kudingeka.
◇Lapho izinga lokushisa lendawo lendawo lifinyelela ku-80℃ noma izinga lokushisa ekhabetheni lidlula u-80℃ ngenxa yokushisa kothintana naye, i-alamu ingakhishwa futhi isinqamuli sesifunda singavulwa ngomzuzwana omncane (uma kudingwa umsebenzisi)
3. Umsebenzi wokusetha
Cindezela ukubambezeleka okude, ukubambezeleka okufushane, khona manjalo, okhiye bomsebenzi wokusetha phansi kanye no-+, - - ukhiye ukuze usethe isikhathi esidingekayo kanye nesikhathi sokulibaziseka ngokuzenzakalelayo ngokwezidingo zomsebenzisi, bese ucindezela ukhiye wokulondoloza ngemva kokufinyelelwa kwesikhathi esidingekayo samanje noma sokulibala.Ukuze uthole imininingwane, bheka isahluko sokufaka, ukusetshenziswa nokugcinwa.Ukulungiselelwa kweyunithi yohambo kungayeka ngokushesha ukusebenzisa lo msebenzi uma kwenzeka iphutha elidlulele.
4. Umsebenzi wokuhlola
Cindezela ukhiye wokusetha ukuze wenze inani elimisiwe libe manje ekubambezelekeni okude, ukubambezeleka okufushane,isimo esisheshayo, igobolondo lenkomba kanye no-+,- ukhiye, khetha inani lamanje elidingekayo, bese ucindezela ukhiye wokuhlola ukuze wenze uhlolo lokukhulula.Kunezinhlobo ezimbili zokhiye bokuhlola; eyodwa ukhiye wokuhlola ongagibeki, kanti omunye ukhiye wokuhlola okhubekayo.Ukuze uthole imininingwane, bheka ukuhlolwa kwedivayisi ekhubekayo kusahluko sokufaka, ukusetshenziswa nokugcinwa.Umsebenzi wokuhlola wangaphambilini ungenziwa lapho i-breaker yesifunda ixhunywe kugridi yamandla.
Uma i-overcurrent yenzeka kunethiwekhi, umsebenzi wokuhlola ungaphazanyiswa futhi ukuvikelwa kwe-overcurrent kungenziwa.
5. Umsebenzi wokuqapha umthwalo
Setha amanani wokusetha amabili, ububanzi bokusetha be-Ic1 (0.2~1) Ku-Ic2, ububanzi bokusetha (0.2~1) Ngaphakathi, isici sokulibaziseka se-Ic1 siyisici somkhawulo wesikhathi esiphambene, inani laso lokusetha ukubambezeleka lingu-1/2 yenani lokusetha lokulibaziseka okude.Kunezinhlobo ezimbili zezimpawu zokulibaziseka ze-Ic2: uhlobo lokuqala yisici somkhawulo wesikhathi esiphambene, inani lokusetha isikhathi lingu-1/4 yenani lokusetha ukubambezeleka okude;uhlobo lwesibili yisici somkhawulo wesikhathi, isikhathi sokulibaziseka singama-60s.Owokuqala usetshenziselwa ukunqamula umthwalo ongabalulekile kakhulu wesiteji esingaphansi lapho owamanje useduze nenani lokusetha ukulayishwa ngokweqile, owakamuva usetshenziselwa ukunqamula umthwalo ongabalulekile wesiteji esiphansi lapho owamanje udlula inani le-Ic1, bese amaconsi amanje ukwenza izifunda eziyinhloko kanye nezifunda ezibalulekile zomthwalo zihlale zinamandla.Uma okwamanje kwehlela ku-Ic2, kukhishwa umyalo ngemva kokulibaziseka, futhi isekethe enqanyulwe yisiteji esiphansi iyavulwa futhi ukuze kubuyiselwe ukunikezwa kwamandla kwesistimu yonke, kanye nesici sokuqapha umthwalo.
6. Umsebenzi wokubonisa weyunithi yokukhubeka
Iyunithi yokukhubeka ingabonisa ukusebenza kwayo kwamanje (okungukuthi umsebenzi we-ammeter) ngesikhathi sokusebenza, ibonise isigaba esicaciswe izici zayo zokuvikela lapho kwenzeka iphutha, futhi ikhiye isibonisi sephutha kanye nephutha lamanje ngemuva kokuphula isekethe, futhi ibonise okwamanje, isikhathi kanye nesigaba. isigaba sesigaba sokusetha ngesikhathi sokusetha.Uma kuyisenzo esibambezelekile, ukukhanya kwenkomba kukhanya ngesikhathi sesenzo, futhi ukukhanya kwenkomba kuyashintsha kusukela ekukhanyeni kuya ekukhanyeni okuqhubekayo ngemva kokuba i-breaker yesifunda inqanyuliwe.
I-7.MCR ivuliwe-off kanye ne-analog tripping ukuvikelwa
Isilawuli singahlonyiswa nge-MCR uma uvaliwe kanye nokuvikela ukuhamba kwe-analog ngokuya ngezidingo zomsebenzisi.Lezi zindlela ezimbili zombili ziyizenzo ezisheshayo.Isignali yamanje enephutha ithumela imiyalelo yesenzo ngokuqondile ngesekhethi yokuqhathanisa izingxenyekazi zekhompuyutha.Ukusetha amanani amanje ezenzo ezimbili ahlukile.Inani lokusetha lokukhubeka kwe-analogi liphezulu, ngokuvamile okuyivelu enkulu yenani lesizinda sokuvikela esisheshayo sesilawuli (50ka75ka/100kA), Isilawuli sisebenza ngaso sonke isikhathi futhi ngokuvamile sisetshenziswa njengesipele.Nokho, inani lokusetha le-MCR liphansi, ngokuvamile li-10kA.Lo msebenzi usebenza kuphela lapho isilawuli sivuliwe, singasebenzi ngesikhathi sokusebenza okujwayelekile okuvaliwe.Umsebenzisi angadinga inani elikhethekile lokusetha ngokunemba okungu-±20%.
I-Mechanical Interlocking
Umshini wokuxhuma ungaxhumanisa ama-circuit breaker amabili noma amathathu kusistimu yokuphakelwa kwamandla eziteshi eziningi.Idivayisi yokuxhuma ngomshini ifakwe ebhodini elingakwesokudla le-breaker circuit.Uma ifakwe ngokuqondile, i-breaker circuit ihlanganiswe nenduku yokuxhuma;uma ifakwe ngokuvundlile noma iqondile, i-breaker circuit ihlanganiswe nekhebula lensimbi, futhi idivayisi ehlanganisiwe ifakwe ngumsebenzisi.Bheka i-Fig. 1 kanye ne-Fig. 2 ukuze uthole umdwebo we-schematic ohlangene.
◇ Induku yokuxhuma exhumanisa ama-circuit breaker amathathu afakwe mpo
◇ Ikhebula lensimbi lixhuma ama-breaker circuit amabili afakwe avundlile
Ubukhulu bomumo nokufakwa
◇ CAW6-1600(200-1600A uhlobo olungashintshi)
