Zoteteza za DIN 30NF250 Transformer Bushing

Imalongosola kutsatira miyezo ya mafakitale aku Germany, kuonetsetsa kuti pali miyeso yeniyeni, zinthu, ndi magwiridwe antchito. Miyezo monga DIN 42531 kapena DIN 42532 nthawi zambiri imaphimba mitundu iyi ya ma bushing.

Imayimira nominal voltage (Un​) rating mu ma kilovolts (kV). Bushing iyi idapangidwira makina amagetsi omwe amagwira ntchito pa 30 kV. Voltage yayikulu kwambiri yamakina (Um​) yomwe imayesedwa nthawi zambiri ndi 36 kV.

“NF” Imasonyeza mtundu kapena mndandanda womwewo malinga ndi muyezo wa DIN. Izi nthawi zambiri zimatanthauza bushing yakunja yoyenera kugwiritsidwa ntchito ndi ma transformer odzazidwa ndi mafuta.

Ntchito

Amapereka chitetezo chamagetsi pakati pa kondakitala wamoyo ndi thanki ya transformer, amapereka njira yolowera kondakitala, amagwira ntchito ngati malo olumikizirana akunja, ndikutseka kutsegula kwa thanki ya transformer.

Kugwiritsa ntchito

Amagwiritsidwa ntchito makamaka kumbali ya ma transformer ogawa magetsi amphamvu apakati, odzaza mafuta kapena ma transformer ang'onoang'ono amphamvu omwe amagwira ntchito mu gulu la magetsi a 30 kV. Nthawi zambiri amaikidwa panja.

Zinthu Zofunika

Kawirikawiri imapangidwa ndi porcelain yamagetsi yapamwamba kwambiri (nthawi zambiri imakhala yofiirira kapena yaimvi), yodziwika bwino chifukwa cha mphamvu zake zotetezera kutentha komanso kulimba kwake. Zipangizo zopangidwa ndi zinthu zosiyanasiyana (monga rabara ya silicone pamwamba pa fiberglass core) zimagwiritsidwanso ntchito.

Ntchito yomanga

Ili ndi ndodo yapakati yoyendetsera magetsi, thupi loteteza kutentha (porcelain kapena composite) lokhala ndi mashedi akunja (masiketi) kuti liwonjezere mtunda woyenda ndikuletsa kugwedezeka m'malo oipitsidwa kapena onyowa, kuyika zida (monga flange) kuti zigwirizane ndi transformer, ndi ma terminals kumapeto onse awiri kuti alumikizane ndi magetsi (mkati mwa lead yozungulira, kunja kwa chingwe chamagetsi/chingwe).
