I-KYN28A-12(Z)(GZS1) yohlobo lwe-switchgear yensimbi ekhishwa insimbi ye-AC ekhishwayo, ifanele isistimu yamandla ye-AC 50Hz yezigaba ezintathu, esetshenziselwa ukwamukela nokusabalalisa amandla kagesi nokulawula, ukuvikela nokuqapha isekethe.
Lo mkhiqizo uhlangabezana namazinga: I-GB3906 “I-switchgear yamanje evalekile yensimbi eshintshwayo kanye negiya lokulawula lamandla kagesi akalwe ngaphezu kuka-3.6kV nokufika futhi ahlanganise 40.5kV”, GB/T11022 “Izincazelo ezivamile zezindinganiso zokushintshwa kwamandla kagesi aphezulu”, i-lEC60298 “ I-switchgear yensimbi efakwe i-AC kanye negiya lokulawula elilinganiswe ngama-voltage angaphezu kuka-1 kV nokufika futhi kuhlanganise no-52kV” .
Imibandela Yokusebenzisa Okuvamile
● Izinga lokushisa lomoya elizungezile: -15℃~+40℃.
● Izimo zokuswakama: Umswakama omaphakathi wansuku zonke ohlobene: ≤95%.
Isilinganiso sansuku zonke sokucindezela komhwamuko wamanzi ≤2.2kPa.
Isilinganiso sanyanga zonke somswakama ohlobene singama-90%.
Isilinganiso sanyanga zonke somfutho womoya wamanzi ngu-1.8kPa.
● Ukuphakama: ● Amandla okuzamazama komhlaba: ≤8 degrees.
● Umoya ozungezile akufanele ungcoliswe kakhulu igesi ebolayo noma evuthayo, umhwamuko wamanzi, njll.
● Izindawo ezingenakho ukudlidliza okuvamile.
● Uma isetshenziswa ngaphansi kwezimo ezijwayelekile ezedlula i-GB3906, umsebenzisi nomkhiqizi bazoxoxisana.
Izici Zomkhiqizo
● Indawo ebiyelwe yomkhiqizo yenziwe ngokuphelele ngeshidi lensimbi elakhiwe nge-aluminium-zinc elicutshungulwe ngamathuluzi omshini futhi lihlanganiswe namabhawudi ngemva kokugoba nokwakheka okuningi. Inamandla aphezulu emishini, eqinisekisa ngempumelelo ukuhlanzeka nobuhle bomkhiqizo. Umnyango wekhabhinethi umbozwe ngepulasitiki. Inokumelana nomthelela oqinile nokumelana nokugqwala, kanye nendawo ebiyelwe yomkhiqizo enezinga lokuvikela le-IP4X.
● Iswishi eyinhloko yalo mkhiqizo ingahlonyiswa nge-VD4 uhlobo lwe-vacuum breaker kanye ne-C3 yochungechunge lwe-fixed load switch ekhiqizwa i-ABB, futhi ingafakwa ngezinhlobonhlobo zama-circuit breaker asekhaya (njenge-VS1, VH1, VK, ZN28) esikhundleni somkhiqizo ofanayo wangaphandle.
● Kungakhathaliseki ukuthi i-circuit breaker ekhethiwe, ibanga lokufakwa komoya lekhondatha elingenalutho lingaqinisekiswa ukuthi likhulu kuno-125mm, futhi ukwahlukanisa okuyinhlanganisela kungaphezu kuka-60mm. Ama-circuit breaker anezinzuzo eziyingqayizivele zempilo ende, imingcele ephezulu, ukugcinwa okuphansi, nosayizi omncane. I-KYN28-12 metal-claded metal-claded switchgear-enclosed metal-enclosed switchgear ifaneleka ku-3.6-12kV amagridi kagesi ezigaba ezintathu ze-AC 50Hz, esetshenziselwa ukwamukela nokusabalalisa amandla kagesi, kanye nokulawula, ukuqapha nokuvikela amasekhethi. Ingasetshenziselwa ibhasi elilodwa, uhlelo lwesigaba sebhasi elilodwa noma uhlelo lwamabhasi amabili. I-switchgear ithobelana ne-IEC298 “i-AC metal-enclosed switchgear kanye negiya lokulawula lama-voltage akalwe ngenhla kwe-1kV futhi afika futhi ahlanganise no-52kV”, IEC694 “Izigatshana ezivamile zezindinganiso zegiya elinamandla kagesi kanye negiya lokulawula” I-China GB3906 ” Iswishi yensimbi yamanje nevaliwe izinto zokulawula amandla kagesi akalwe ngaphezu kuka-3.6kV futhi afika futhi ahlanganise 40.5kV” kanye ne-DL404 “I-alternating-current metal-enclosed switchgear kanye ne-controlgear yama-voltage akalwe angaphezu kuka-3.6kV afika futhi ahlanganise no-40.5kV” Germany 0670 “Ac switchgear and controlgear for voltages ngaphezu kwe-1kV” namanye amazinga. Futhi inomsebenzi ophelele futhi onokwethenjelwa wokulwa ne-misoperation.

Imisebenzi
Isakhiwo se-switchgear siboniswa esithombeni esingezansi. Isakhiwo somhlangano we-metal-metal modular, umzimba wekhabhinethi wenziwe ngepuleti ye-aluminium-zinc engenisiwe enekhono eliqinile lokulwa nokugqwala, ngaphandle kokwelashwa okungaphezulu, okucutshungulwe yimishini ye-CNC yokunemba okuphezulu, kusetshenziswa ubuchwepheshe obuphambili bokugoqa okuningi, ukuxhumana Ixhunywe nayo. amantongomane ayimpumputhe e-rivet nama-bolts anamandla amakhulu, ngokunemba okuphezulu, isisindo esincane namandla amahle.
I-switchgear ingafakwa ngochungechunge lwe-ZN63A-12 (VS1), uchungechunge lwe-VD4, uchungechunge lwe-ZN65 namanye ama-vacuum breaker akhiqizwa yi-Ghorit, anokuguquguquka okubanzi nokushintshashintsha okuqinile. Inqola yesandla ifakwe indawo yokusebenza, indawo yokuhlola, futhi indawo ngayinye inedivayisi yokuma neyokubonisa, ephephile futhi ethembekile.
Igumbi lekhebula lingahlonyiswa ngezintambo eziwumgogodla owodwa ongu-9. Imishini inokhiye othembekile wemishini kanye nogesi ukuze uhlangabezane ngokugcwele nezidingo "zokuvimbela ezinhlanu". Igumbi ngalinye lifakwe imigudu yokusiza ingcindezi ukuze kuqinisekiswe ukuphepha komuntu siqu ngesikhathi sokusebenza.
