Kutembenuza kwa Voltage Yaikulu
01
EN 24KV250 Transformer Bushing Type 3
Kanema
kukula
Muyezo: EN 50180 / EN 60137 (Miyezo yaku Europe ya HV bushings)
Voltage Yoyesedwa: 24 kV (voltage ya dongosolo)
Mtundu Wosankhidwa: Mtundu 3
Kuchuluka kwa Pakadali pano: 250 A (kopitilira)
Mulingo Woyambira Woteteza (BIL): 125 kV
Zosankha Zazinthu:
Kunja: Porcelain
Kutchinjiriza Mkati: Pepala lamafuta
Mtunda wa Creepage: ≥450 mm
Kuyika: Flange kapena mtundu wa through (zimadalira kapangidwe ka transformer)
Mapulogalamu Oyambirira
Ma transformer ogawa mafuta (kalasi ya 20/24 kV)
Zosinthira zoyikidwa pa Pad kapena substation
Makina a mphamvu zongowonjezedwanso (ma transformer a mphepo/dzuwa)
Magawo amphamvu a mafakitale (migodi, mafakitale achitsulo)
Zomangira panja (kapangidwe koteteza nyengo)
Kutsatira Miyezo: EN 50386
Kugwiritsa Ntchito & Kugwiritsa Ntchito:
Udindo Waukulu:
Amapereka chitetezo chamagetsi komanso chithandizo chamakina kwa ma conductors omwe amadutsa mu thanki ya transformer.
Makonzedwe Ofala:
Ma transformer amphamvu (magawo ogawa/malo osinthira magetsi).
Zida zosinthira magetsi, ma reactor, kapena ma capacitor banks.
Yoyenera ma transformer oviikidwa mu mafuta kapena ouma.
Ntchito Zofunika Kwambiri:
Zimaletsa ma circuit afupikitsa pakati pa ma conductor amoyo ndi zida zokhazikika.
Amatseka mafuta/gasi wa transformer (ngati kuli koyenera).
Imapirira kupsinjika kwa chilengedwe (kuipitsa, chinyezi, UV).
Zosiyanasiyana ndi Njira Zina:
Mapepala ophimbidwa ndi mafuta (a ma transformer odzazidwa ndi mafuta).
Ma bushings a mtundu wouma kapena epoxy resin (osagwiritsidwa ntchito popanda kukonza).
Ma bushings a SF₆-insulated (a machitidwe otetezedwa ndi mpweya).
Kufotokozera Kwathunthu
Kugwiritsa ntchito
Amagwiritsidwa ntchito makamaka poyika panja pa ma transformer ogawa mkati mwa makina amagetsi a 20 kV m'madera otsatira miyezo ya EN. Amasankhidwa makamaka pamene kapangidwe ka transformer kakufuna mawonekedwe akuluakulu oyika a Type 3.
Zinthu Zofunika
Kawirikawiri amapangidwa ndi zinthu zopangidwa ndi porcelain yamagetsi yapamwamba kwambiri (nthawi zambiri zofiirira kapena zofiirira) kapena zinthu zopangidwa ndi zinthu zosiyanasiyana (monga zitseko za rabara za silicone pamwamba pa fiberglass core).
Ntchito
Imateteza bwino kondakitala wamoyo kuchokera ku thanki yomwe yakhazikika pansi, imapereka njira yotsekedwa ya kondakitala, imapereka chithandizo chamakina, ndipo imagwira ntchito ngati malo olumikizirana akunja. Gulu la Mtundu Wachitatu limatsimikizira kuti likugwirizana ndi matanki a transformer okonzedwa ndi dongosolo lalikulu loyikira.
Mtunda Wozungulira
Gawo ili (monga 525 mm, 600 mm, 720 mm, ndi zina zotero) liyenera kusankhidwa kutengera kuchuluka kwa kuipitsidwa kwa chilengedwe komwe matabwa adzayikidwe, motsatira malangizo a miyezo ya EN/IEC.
