Bu çalışmada, transformatörlerin kazan kapağı üzerinde alçak gerilim sargılarının bağlantı uçları sebebiyle meydana gelen ve yüksek sıcaklıklara da neden olan eddy akımı kayıpları incelenmektedir. Bu kayıpların azaltılması amacıyla kazan kapağı tasarımı manyetik özellikli olmayan paslanmaz çelik malzeme kullanılarak iyileştirilmektedir. Bu iyileştirme çalışması sırasında imalat koşulları ve maliyet kriterleri de göz önünde tutulmaktadır. Farklı tasarımlar için manyetik akı dağılımları ve eddy akımı kayıpları üç boyutlu sonlu elemanlar yöntemi yardımıyla analiz edilmiş ve deneysel olarak da doğrulanmıştır. Elde edilen sonuçlar, kazan kapağı üzerinde alçak gerilim buşinglerinin bağlantı yüzeyinin paslanmaz çelikten imal edilen I-biçimli tek parça levha kullanılarak üretilmesi sonucunda kapak üzerinde meydana gelen güç kayıplarının tamamına yakınının ortadan kaldırılabildiğini göstermektedir.

Low voltage winding leads cause local eddy current losses in top-plate of the transformer tank. In this paper, this loss component which also causes local hot spots is investigated. Top-plate design is modified using stainless steel non-magnetic material, around the low voltage bushing holes. Manufacturing issues and cost as well as power losses are considered as main criteria during modification study. Magnetic flux distributions and eddy current losses are analysed and compared for different designs. Comparisons are based on 3D finite element simulations and experimental studies. Obtained results show that, insertion of single I-shaped stainless steel plate reduces eddy current losses around low voltage bushing holes to nearly zero.
