I-Gas Insulated Switchgear GRM6-24

GRM6-24 uchungechunge lwe-SF6 igesi evalekile yensimbi evalekile (ngemuva kwalokhu ebizwa ngokuthii-gas insulated switchgear ) ifanele i-AC 50Hz yezigaba ezintathu, isistimu yokusabalalisa amandla kagesi ka-24kV, ukuphuka nokuvala umthamo wamanje, ukulayisha ngokweqile, ukuvala nokuvala isifunda esifushane. Nqamula imithwalo ye-capacitive efana nama-no-load transformers, imigqa ephezulu, izintambo zekhebula namabhange e-capacitor ebangeni elithile, futhi udlale indima yokusabalalisa amandla, ukulawula nokuvikela ohlelweni lwamandla. I-GRM6-24 yamukela isakhiwo esivalekile ngokugcwele, zonke izindikimba ezishajwayo zivalwa egumbini lomoya elishiselwe amapuleti ensimbi engagqwali, futhi izinga lokuvikela lifinyelela ku-IP67. Kuyi-switchgear yenethiwekhi eyindilinga eneziyingi eziningi esebenza ngokuphephile futhi enokwethenjelwa okuphezulu engakwazi ukuzivumelanisa nezimo zemvelo ezihlukahlukene ezinzima njengenkungu emanzi nenosawoti, njengezikhukhula nokungcola okukhulu. Isetshenziswa kakhulu emapaki ezimboni, emigwaqweni, ezikhumulweni zezindiza, ezindaweni zokuhlala, ezikhungweni zezentengiselwano eziphithizelayo, njll. Iwumshini olungele ukusabalalisa inethiwekhi ezishintshayo. Ibuye isetshenziswe: iziteshi ezincane zohlobo lwamabhokisi ahlangene, amabhokisi egatsha ekhebula, i-switchgear, iziteshi zamandla omoya, amalambu angaphansi komhlaba kanye nomhubhe.

GRM6-24 Amamojula Atholakalayo

•layisha i-switch break module

• ikhebula lemojula eneswishi yomhlaba

• Imojula yokuxhuma ikhebula ngaphandle kokushintsha komhlaba

• imojula kagesi yenhlanganisela ye-switch-fuse

• Imodyuli ye-vacuum circuit breaker

• imojula yokushintsha ingxenye yebha (switch load)

• imojuli yokushintsha ingxenye yebha yebhasi (i-vacuum circuit breaker)

• I-SV njalo ihlangene nemojuli yokuphakamisa ibha yebhasi

• ibhasi grounding module

• Imojula yemitha

Sebenzisa Isimo

• Izinga lokushisa le-ambient: -40℃~+40℃ (ngezansi -30℃ kufanele kuxoxiswene ngalo ngumsebenzisi nomkhiqizi);

• Ukuphakama:

• Amandla okuzamazama komhlaba: akukho ngaphezu kwama-degree angu-8;

• Isilinganiso esiphezulu somswakama ohlobene: 24h isilinganiso

• Izindawo ezingenamlilo, ukuqhuma, ukugqwala kwamakhemikhali kanye nokudlidliza okunodlame.

Isici Sesakhiwo

• Idizayini evalekile ngokugcwele futhi evalekile ngokugcwele: Zonke izingxenye ezibukhoma ze-GRM6-24 zivaliwe ebhokisini elishiselwe ipuleti lensimbi engagqwali elingu-304, ibhokisi ligcwele igesi ye-SF6 enokucindezela kokusebenza okungu-1.4bar, futhi izinga lokuvikela yi-IP67. Ifanele ukufakwa ezindaweni ezinomswakama ophezulu kanye nokungcola kothuli, ikakhulukazi ezifanele izimayini, iziteshi ezincane zohlobo lwamabhokisi nanoma yiziphi izindawo ezijwayele ukuvela ngaphandle ngenxa yokungcoliswa komoya. Umkhiqizo ufakwe ngomkhono ojwayelekile we-DIN47636, futhi uxhunywe kukhebuli ngejoyinti lekhebula elivaleke ngokuphelele, elivalwe ngokugcwele, nelivikelwe.

• Ukuthembeka okuphezulu nokuphepha komuntu siqu: zonke izingxenye ezibukhoma zivaliwe ekamelweni lomoya le-SF6; ikamelo lomoya linesiteshi sokusiza ingcindezi enokwethenjelwa, esidlule ukuhlolwa kwe-arc yephutha langaphakathi le-20kA/0.5s: inkinobho yokulayisha kanye ne-grounding switch yizimo ezintathu ezishintshayo, okwenza kube lula ukuhlangana phakathi kwabo. Kukhona ukuxhuma okuthembekile komshini phakathi kwesembozo sekhompathi yekhebula kanye neswishi yokulayisha, okungavimbela ngempumelelo ukungena esikhawulweni esibukhoma ngephutha.

• Umjikelezo wempilo ongalondolozi futhi ende Umkhiqizo uklanywe ngomjikelezo wempilo weminyaka engama-30. Phakathi nomjikelezo wempilo yomkhiqizo, iswishi eyinhloko ayidingi ukulungiswa. Izinga lokuvuza lonyaka lomkhiqizo ngu-

• Isakhiwo esihlangene: Ngaphandle kwekhabhinethi yemitha ye-air-insulated kanye nekhabhinethi ye-PT, wonke amamojula anobubanzi obungu-350mm kuphela, futhi izintambo zokuxhuma ikhebula zawo wonke amayunithi anobude obufanayo phansi, obulungele ukwakhiwa endaweni.

• I-GRM6-24 ingalungiselelwa ngamadivayisi okulawula ahlakaniphile (ongakukhetha), inikeze isivikelo esisebenzayo, isilawuli kude nezinhlelo zokuqapha, kanye nokusekela ukuzenzekelayo kwezinhlelo zokusabalalisa amandla.

• I-GRM6-24 ihlinzeka ngezindlela ezimbili zokuvikela ama-transformer: inhlanganisela ye-fuse yokushintshanisa umthwalo kanye ne-circuit breaker enokuvikelwa kwe-relay. Izinto zikagesi ezihlanganisa i-fuse ye-load switch zisetshenziselwa ama-transformer angu-1600kVA nangaphansi, kuyilapho ama-circuit breaker anama-relay angasetshenziswa ukuvikela i-transformer yamakhono ahlukahlukene.

• Ukuvikelwa kwemvelo: Ukuthuthukiswa kwe-GRM6-24 akubandakanyi umkhiqizo ngokwawo kuphela, kodwa futhi nokuvikelwa kwemvelo kusukela kunqubo yokukhiqiza kuya ekusebenzeni kwesikhathi eside kweswishi. Zonke izinto zokwakha zikhethwa ukuthi zibe nobungane bemvelo, futhi kwamukelwa inqubo yokuhlanza i-zero-leakage. Umkhiqizo uvalelwa impilo yonke, futhi u-90% kuya ku-95% wezinto ezibonakalayo zingagaywa kabusha ngemva kokuphela komjikelezo wempilo yomkhiqizo.

Imingcele Eyinhloko Yezobuchwepheshe

Qaphela:

1 ) Kuncike kumthamo olinganiselwe we-fuse;

2) Ikhawulelwe i-fuse yamandla kagesi aphezulu.
