I-6kV-220kV I-Wall bushing

Imikhiqizo eyinhloko ekhiqizwa inkampani ihlanganisa:

12kV ~ 252kV irabha efakwe i-fiber capacitive wall bushing;

12kV ~ 252kV capacitive composite bushing odongeni;

12kV ~ 252kV capacitive porcelain odongeni bushing;

40.5kV ~ 252kV udonga olomile olunamandla kagesi aphezulu olunomshini wamanje;

35kV ~ 126kV uhlobo olomile lwe-transformer yamanje yamandla aphezulu;

10kV ~ 35kV i-coupler capacitive ehlanganisiwe;

Inkampani yethu inamandla ezobuchwepheshe aqinile, ubuchwepheshe obuphambili, uhlelo lokuphatha oluphelele, imishini yokuhlola ikhwalithi ephelele, kanye nomkhiqizo oqinile we-R & D namandla okukhiqiza. Ihambisana nefilosofi yebhizinisi "yokuthambekela emakethe, ikhwalithi njengempilo, ukuphatha njengokuyisisekelo, isayensi nobuchwepheshe kuqala, okugxile kubantu", inkampani ikhuthaza isiko lebhizinisi lobuqotho, ukusungula izinto ezintsha, ukusebenza kahle nokuvumelana, isebenzela umphakathi ngezinga eliphezulu- imikhiqizo yekhwalithi namanani aphusile, futhi ihlangabezana nezidingo ezihlukene zamakhasimende. Ububanzi bebhizinisi lenkampani lusatshalaliswa kuwo wonke amazinga amagridi kagesi namaphrojekthi amakhulu wamandla e-China, futhi ihlinzeka ngekhwalithi ephezulu ye-silicone eyinhlanganisela yenjoloba esekela imikhiqizo esekela abakhiqizi bemishini kagesi abadumile emhlabeni wonke.

2, Isingeniso somkhiqizo

I-Fcrgj glue impregnated fibre capacitive wall bushing kancane kancane inciphisa amandla kagesi aphezulu ngokusebenzisa isimiso sokuhlukanisa i-capacitive voltage. Ekusebenzeni okuvamile, ukuhola kwesikrini sokuphela kuyalingana ne-flange futhi kusekelwe ku-flange. Ukuze umthofu we-high-voltage ukwazi ukudlula odongeni noma phansi ngokuphepha futhi udlale indima yokwehlukanisa nokusekela ukuphambukisa.

Yakhiwe ngokusonta okuyisisekelo, i-sheath yangaphandle, isiketi sesambulela serabha ye-silicone, ikhava yokulinganisa ukucindezela emikhawulweni yomibili, i-flange kanye ne-conductive wire clamp.

3. Ukwakhiwa kwezindonga

Isibonelo, incazelo ye-fcrgj-24 / 3150: i-rubber impregnated fibre capacitive wall bushing ene-voltage elinganiselwe engu-24kV kanye nesilinganiso samanje esingu-3150A.

Incazelo ye-fcrgj-252 / 2500: glue impregnated fibre capacitive wall bushing ene-voltage elinganiselwe engu-252kV kanye nesilinganiso samanje esingu-2500A.

4. Izimo zokusebenzisa:

1. Izimo zomoya ezizungezile: izinga lokushisa lomoya elizungezile: ubuningi obungu-55 ℃, ubuncane - 60 ℃.

2. Ukukhethwa kwebanga elithile le-creepage kuzohambisana nezinhlinzeko ze-GB / T 5582.

Ibanga elithile le-Creepage lihlukaniswe ngamaleveli angu-4:

Ikilasi I: 16mm / kV; Isigaba II: 20mm / kV; Isigaba III: 25mm / kV; Ibanga IV: 31 mm / kV

Iphutha elivumelekile elibi elivumelekile lebanga langempela le-creepage le-bushing ngu-0.04l + 1.5mm (L: ibanga elincane le-creepage le-creepage).

Uma umsebenzisi engenazo izidingo, okumisiwe kungu-31mm/kV

5, Imingcele yezobuchwepheshe eyinhloko yomkhiqizo

1. Ithebula 1 linikeza i-voltage elinganiselwe, i-voltage yokusebenza yesistimu, yamanje elinganiselwe, izinga lokuhlukanisa kanye neminye imingcele yohlobo lwe-fcrgj yodonga.

2. Ngaphansi kwe-voltage engu-1.05ur / √ 3 kanye ne-ur, isici sokulahlekelwa kwe-dielectric TG δ ≤0.4%.

3. Umthamo wokukhipha wendawo: ≤ 5pc ngaphansi kwe-voltage elinganiselwe ye-1.05ur / √ 3.

4. Ukunyuka kwezinga lokushisa ≤ 60K, ukusebenza kwesikhathi eside ku-inom yamanje elinganiselwe

5. Umsinga okwazi ukumelana nokushisa: ith = 25inom, 3C

6. Ezinye izimo zobuchwepheshe zizohambisana namazinga e-IEC 60137-2017 kanye ne-GB / T 4109-2008 ama-insulating bushings ane-AC voltage ephakeme kuno-1000V.

6, Ezokuthutha kanye nokuphakanyiswa

1. Ukuthuthwa komkhiqizo

1.1 imikhiqizo ingathuthwa ngesitimela, umkhumbi, imoto, indiza nezinye izinto zokuhamba. Indawo yesitimela, indawo yomkhumbi kanye nendawo yezimoto ethwala imikhiqizo kufanele igcinwe ihlanzekile futhi ingenazo izinto ezingcolisayo.

1.2 ukulayishwa kwemikhiqizo kuzohlangabezana nezidingo emithethweni yezokuthutha, futhi imikhiqizo izobekwa ngokuqinile. Akukho ukuzamazama, ukungqubuzana nokunyakaza okuvunyelwe ngesikhathi sokuthutha.

1.3 ngesikhathi sokuthutha umkhiqizo, ukuthambekela akufanele kube kukhulu kuno-30 °.

1.4 ngemva kokuba imikhiqizo idluliselwe esikhumulweni semikhumbi noma yehliswa esikhumulweni sezindiza, ukupakishwa akufanele kudlule izingqimba ezintathu, futhi ezinye izinto azivunyelwe ukuthi zipakishwe nazo.

ISIHLOKO-UHLOBO-1

Ama-capacitor ahambisanayo kagesi aphezulu afanele ukuxhumana okuhambisanayo kumasistimu kagesi e-AC anefrikhwensi yamandla (50Hz noma 60Hz) we-1kV nangaphezulu. Asetshenziselwa ukunxephezela amandla asebenzayo e-inductive, ukuthuthukisa isici samandla, ukuthuthukisa ikhwalithi kagesi, ukunciphisa ukulahleka kolayini, nokusebenzisa ngokugcwele ukusebenza kahle kokuphehla ugesi kanye nezisetshenziswa zokuphakela.
