Kutembenuza kwa Voltage Yaikulu

DIN 24KV250 Transformer Bushing Insulators CD525
Kanema
Mafotokozedwe Akatundu
Chotchingira cha DIN 24kV 250A Transformer Bushing chokhala ndi Creepage Distance (CD) ya 525mm.
Mafotokozedwe: Muyezo woyenera mwina ndi DIN 42531, yomwe imakhudza makamaka ma bushing akunja a ma transformer mu magulu amagetsi a 12 kV ndi 24 kV.
Mphamvu ya Voltage: 24kV (Um)
Izi zikutanthauza mphamvu yamagetsi yapamwamba kwambiri yomwe insulator imapangidwira kuti igwire ntchito mosalekeza. Izi nthawi zambiri zimagwirizana ndi mphamvu yamagetsi yokhala ndi mphamvu yamagetsi (Un) ya 20 kV.
Kuyeza kwa Pakali pano: 250A
Izi zikutanthauza mphamvu yokhazikika yomwe woyendetsa bushing amatha kuigwira popanda kupitirira malire a kutentha.
Mtunda wa Creepage (CD): 525mm
Uwu ndi mtunda waufupi kwambiri pamwamba pa insulator pakati pa terminal yolimbikitsidwa ndi flange yokhazikika. Mtunda wokwera wa 525 mm ndi wodziwika bwino wa ma bushing a 24kV (Um) omwe amapangidwa kuti agwiritsidwe ntchito panja pansi pa mikhalidwe yabwinobwino kapena yocheperako mpaka yocheperako (monga, yofanana ndi Pollution Level I kapena II).
Kufotokozera Kwathunthu
Chigawochi ndi chotchingira chakunja cha transformer chomwe chapangidwa motsatira miyezo ya ku Germany kuti chigwiritsidwe ntchito pa ma transformer odzaza mafuta omwe amagwira ntchito mkati mwa ma network a 20 kV nominal voltage (mpaka 24 kV maximum system voltage). Chimapereka njira yotetezeka komanso yodalirika kuti kondakitala wonyamula mpaka 250A adutse pakhoma la thanki lokhazikika la transformer pamene akusunga kutchinjiriza kwamagetsi.
Zinthu Zofunika
Kawirikawiri amapangidwa kuchokera ku porcelain yamagetsi yapamwamba kwambiri (nthawi zambiri imakhala ndi glaze yofiirira) chifukwa cha mphamvu zake zabwino zotetezera kutentha komanso kukana nyengo.
Ntchito yomanga
Ili ndi ndodo yapakati ya conductor, thupi lalikulu lotetezera kutentha lomwe lili ndi ma sheds a nyengo (masiketi) kuti liwonjezere njira yothandiza pamwamba (kusweka) ndikuletsa kuphulika, flange yoyikira kuti imamatire bwino ndi kukhazikika ku transformer, komanso malo olumikizira kumapeto onse awiri.
Kugwiritsa ntchito
Amagwiritsidwa ntchito kwambiri mbali yamagetsi amphamvu kwambiri ya ma transformer odzaza mafuta omwe amapezeka m'malo osungiramo zinthu akunja kapena malo oyikapo ndodo m'makina ogawa a 20 kV. Mtunda wa 525mm wokwera umapangitsa kuti ukhale woyenera malo akunja komwe kuipitsidwa kwambiri si vuto lalikulu.
