EN 24kV250A Transformer Bushing Type 2

H=385mm

D=150mm

Kutalikirana kwa Creepage: Min525mm

Voltage Yovomerezeka: 24KV

Yoyesedwa Pakali pano: 250A

Mphamvu Yothamanga Yopirira Voltage Youma: 70KV

Muyezo

EN - Imasonyeza kutsatira Malamulo aku Europe (miyezo yopangidwa ndi mabungwe okhazikitsa miyezo aku Europe monga CENELEC). Pa ma bushing amtunduwu, EN 50180 ("Ma bushings mpaka 36 kV ndi kuyambira 250 A mpaka 3,15 kA a ma transformer odzazidwa ndi madzi") ndi yofunika kwambiri chifukwa imatchula miyeso ndi mitundu yosinthira. Zofunikira zonse mwina zimagwirizananso ndi EN IEC 60137 ("Ma bushings otetezedwa a ma voltages osinthika opitilira 1000 V").

Voltage Yovomerezeka 24KV

Munthawi ya muyezo wa EN, izi nthawi zambiri zimatanthauza mphamvu yayikulu yamagetsi (Um). Mphamvu yofanana yamagetsi yamagetsi (Un) nthawi zambiri imakhala 20 kV.

Yoyesedwa Pano 250A

Iyi ndi mphamvu yokhazikika (Ir) yomwe bushing imatha kunyamula.

Mtundu wachiwiri umatanthauza mtundu wa mawonekedwe omwe afotokozedwa mu EN 50180. Ma bushing a mtundu wachiwiri ali ndi miyeso yofanana, makamaka ya flange yokonzera ndi kumapeto kwapansi (kulumikizana kwa mbali yamafuta), kuonetsetsa kuti zinthu zosiyanasiyana za opanga zikugwirizana ndi muyezo. Pa mulingo wa 24kV 250A, miyeso ya Mtundu wachiwiri nthawi zambiri imachokera ku zomwe zafotokozedwa m'mbiri mu muyezo wa Germany DIN 42531.

Iyi ndi transformer bushing yopangidwa motsatira miyezo ya ku Ulaya (EN) kuti igwiritsidwe ntchito pa ma transformer odzaza madzi (nthawi zambiri amafuta amchere). Imayesedwa pamakina amagetsi okhala ndi voteji ya 20kV (yokwera kwambiri 24kV) ndipo imatha kuyendetsa mpaka 250A nthawi zonse.

Kugwiritsa ntchito

Cholinga chake chachikulu ndi kuyika panja pa ma transformer ogawa omwe amagwiritsidwa ntchito mu ma network amagetsi a 20 kV ku Europe ndi madera ena omwe amagwiritsa ntchito miyezo ya EN.

Zinthu Zofunika

Kawirikawiri amapangidwa kuchokera ku porcelain yamagetsi yapamwamba kwambiri (yokhala ndi bulauni kapena imvi) kapena zinthu zomwe zingakhale zophatikizika (zitseko za rabara za silicone pamwamba pa fiberglass core).

Ntchito

Amapereka chitetezo chamagetsi chodalirika, amalola kondakitala kudutsa mu thanki ya transformer, amapereka chithandizo chamakina, amagwira ntchito ngati malo omalizira akunja, ndipo amaonetsetsa kuti chosindikiziracho chili cholimba motsutsana ndi madzi a transformer ndi malo akunja.

Mtunda Wozungulira

Ngakhale kuti "EN 24KV250 Type 2" sinatchulidwe ndi "EN 24KV250 Type 2" yokha, tchire lenilenilo lidzakhala ndi mtunda wodziwika bwino woti lizitha kukwera (monga, 525 mm kapena kuposerapo) wosankhidwa kutengera momwe chilengedwe chimafunira (mlingo wa kuipitsa) malinga ndi miyezo ya EN/IEC.
