Abstract

transformador, método de controlar a ruptura de um transformador durante as condições de excesso de pressão e radiador de um transformador. a presente invenção refere-se a um transformador que inclui um tanque fechado tendo um interior e um radiador encerrado, espaçado do tanque e em comunicação fluida com o interior. o radiador inclui dois painéis unidos para definir um espaço substancialmente fechado. os painéis têm faces opostas e extremidades de fundo. as extremidades de fundo dos painéis são unidas por uma primeira solda e partes das faces opostas dos painéis são unidas por uma pluralidade das segundas soldas. a primeira solda e a pluralidade das segundas soldas são construídas e dispostas de modo que quando ocorre uma condição de excesso de pressão no tanque e assim no radiador, as segundas soldas se romperão uniformemente permitindo que os painéis se expandam em geral uniformemente, direcionando uma ruptura do radiador para ocorrer na primeira solda, sem que qualquer ruptura do tanque ocorra.
