Abstract

anel de graduação para um enrolamento de transformador de ccat ou um enrolamento de reator de ccat a presente invenção refere-se a um anel de graduação (24) para um enrolamento de transformador de ccat ou um enrolamento de reator de ccat. o referido enrolamento compreende um núcleo anular (28), que tem uma superfície condutora (29) e é circundada por uma camada (30) produzida de material de celulose. de acordo com a presente invenção, a referida camada (30) é projetada como um compósito, em que a resistividade do referido compósito é reduzida em comparação a um material de celulose não tratado. isso tem a vantagem de que a queda na voltagem é melhor distribuída sobre a camada (30) do anel de graduação quando um campo de corrente elétrica direta é apicado ao anel de graduação. picos de carga podem assim ser reduzidos, e como um resultado o anel de graduação (24) pode vantajosamente ter uma altura mais baixa (h) e/ou menor raio (r) dos cantos de seção transversal do anel de graduação e/ou uma espessura mais delgada de camada (s) da camada (30). a liberdade de configuração para criar o anel de graduação pode assim vantajosamente ser aumentada e a necessidade de material pode ser reduzida.
