Abstract

Patente de Invenção:<B>"TRANSFORMADOR DE ALTA VOLTAGEM DE DIODO DIVISOR"<D>. A invenção específica um transformador de alta voltagem de diodo divisor que tem um núcleo, um enrolamento primário e um enrolamento de alta voltagem, que é disposto em câmaras (C1-C12) de um formador de enrolamento, no qual as câmaras (C1-C12) com o enrolamento de alta-voltagem, se situam abaixo do enrolamento primário, um revestimento condutivo (15) é disposto sobre a superfície da cavidade interna do formador de enrolamento, e em virtude de um arranjo e enrolamento correspondente das câmaras (C1-C12), oscilações aparecendo durante a operação no transformador de alta voltagem induz correntes capacitivas sobre o revestimento condutivo (15), cuja soma das correntes capacitivas resulta ser aproximadamente zero. Isto pode ser obtido, por exemplo, em que em virtude de um arranjo e enrolamento simétrico das câmaras (C1-C12) em relação aos diodos (3,4), as oscilações induzem correntes capacitivas sobre o revestimento condutivo (15) que ocorrem em pares com a mesma amplitude mas em oposição de fase e desta forma cancela uma com a outra. Em particular em virtude de uma espessura de fundo idêntica e número de espiras aproximadamente idêntico para todas as câmaras (C1-C12), a corrente capacitiva ocorre com a amplitude quantificada, com o resultado que os valores delas podem ser definidos de uma maneira simples já que as capacitâncias parasitas (SC) são idênticas para todas as câmaras (C1-C12). Este arranjo permite ser omitida a conexão à terra (G) não obstante seja preservado o efeito de "peneiramento" do revestimento condutivo (15).
