Abstract

disposição de conexão para enrolamentos de transformador de hvdc ou enrolamentos de reator de hvdc a presente invenção refere-se a uma disposição de conexão (28) para os fios elétricos (29) de enrolamentos de transformador de hvdc (22) ou enrolamentos de reator de hvdc. de acordo com a invenção, pelo menos a camada de isolamento (30) de um tubo de eletrodo (21) é, e de preferência, também as barreiras sólidas (26,32), são produzidas a partir de um material de celulose, a resistividade do qual é diminuída, por meio de um tratamento quando comparado ao material de celulose não tratado e fica assim em linha com a resistividade do óleo de transformador. isso permite que mais economia de espaço e mais seções de isolamento à prova de perfuração (25) sejam produzidas para o componentes de hvdc mencionados acima, o que aumenta, de maneira vantajosa, a liberdade de design para a criação das ditas disposições de conexão.connection arrangement for hvdc transformer windings or hvdc reactor windings The present invention relates to a connection arrangement (28) for the electrical wires (29) of hvdc transformer windings (22) or hvdc. according to the invention at least the insulating layer (30) of an electrode tube (21) is, and preferably also the solid barriers (26,32), are produced from a cellulose material, the resistivity which is decreased by treatment as compared to untreated cellulose material and thus is in line with the resistivity of the transformer oil. This allows more space-saving and more puncture-proof insulation sections (25) to be produced for the aforementioned hvdc components, which advantageously increases the design freedom for creating said connection arrangements.
