Abstract

En la presente invención se divulga una estructura de compensación para reducir la corriente de circulación en una ventana de un transformador y un transformador que comprende la estructura de compensación. La estructura de compensación para reducir la corriente de circulación en una ventana de un transformador, el transformador que comprende un devanado (20), un armazón de metal (10) y conductores (50) ubicados en un lado del armazón y separados del armazón, el armazón (10) que comprende bordes y un núcleo de hierro (14) ubicado dentro de una ventana encerrada por los bordes, el devanado (20) que se proporciona alrededor del núcleo de hierro (14), en donde la estructura de compensación comprende al menos un compensador (30; 30') proporcionado en los bordes del armazón (10), el al menos un compensador se elaborada de láminas de acero al silicio de un material magnético, y el al menos un compensador separa al menos una parte de los bordes del armazón (10) de una parte de los conductores (50). La estructura de compensación de la presente invención separa estructuras de hierro entre un lado de alto voltaje y un lado de bajo voltaje, incrementa la impedancia entre el circuito de ventana del armazón y el circuito de corriente de conductores externos, reduciendo de este modo de manera significativa la corriente inducida dentro del armazón y evitando efectos dañinos.
