Abstract

BUCHA PARA UM SISTEMA DE ENERGIA E SISTEMA COMPREENDENDO TAL BUCHA. Bucha (1) que compreende um núcleo condensador disposto para alojar um condutor elétrico (15) ao longo de um eixo central (X) do núcleo do condensador (3), em que a bucha (1) tem uma parte de extremidade afilada (3 - 2a) disposta para estar em contato com um fluido dielétrico tendo maior resistência dielétrica de força do que o ar, a parte da extremidade afilada (3-2a) que apresenta uma superfície que tem uma primeira parte (4-1) com uma primeira inclinação (I-1) em uma direção axial e uma segunda parte (4-2) com uma segunda inclinação (I-2) na direção axial, em que a segunda inclinação (I-2) é diferente da primeira inclinação (I-1). A parte de extremidade afilada (3-2a) do núcleo condensador compreende camadas condutoras dispostas concentricamente em torno do eixo central (X), em que as camadas condutoras estão dispostas numa formação de escada axialmente, com uma camada condutora mais profunda tendo uma borda que define a primeira etapa e a camada condutiva mais profunda tendo uma borda que define a última etapa. Um sistema que compreende tal bucha também é apresentado aqui.BUSHING FOR A POWER SYSTEM AND SYSTEM COMPRISING SUCH BUSHING. Bushing (1) comprising a capacitor core arranged to house an electrical conductor (15) along a central axis (X) of the capacitor core (3), wherein the bushing (1) has a tapered end portion (3 - 2a) arranged to be in contact with a dielectric fluid having greater dielectric strength strength than air, the tapered end part (3-2a) having a surface having a first part (4-1) with a first inclination (I-1) in an axial direction and a second part (4-2) with a second inclination (I-2) in the axial direction, wherein the second inclination (I-2) is different from the first inclination (I- 1). The tapered end portion (3-2a) of the capacitor core comprises conductive layers arranged concentrically about the central axis (X), wherein the conductive layers are arranged in a ladder formation axially, with a deeper conductive layer having an edge that defines the first step and the deeper conductive layer having an edge that defines the last step. A system comprising such a bushing is also presented here.
