Abstract

patente de invenção: descarregador de sobretensão. a presente invenção refere-se a um descarregador de sobretebsão que tem: um elemento interni de descarregador de sobretensão produzido por meio do empilhamento de uma pluralidade de resistores não lineares; um contêiner de isolamento em forma de cilindro que aloja o elemento interno de descarregador de sobretensão e que aloja um gás de isolamento no interior do mesmo; um condutor lateral de alta-tensão provido em uma porção de extremidade do contêiner de isolamento de maneira a formar uma superfície exposta que fica exposta para o lado de dentro do contêiner de isolamento, e eletricamente conecatdo ao elemento interno de descarregador de sobretensão; e uma camada de resina isolante que cobre pelo menos uma porção de limite entre a superfície exposta do condutor laterak de alta-tensão e uma superfície interna do contêiner de isolamento.patent: overvoltage arrester. The present invention relates to a surge arrester having: an internal surge arrester member produced by stacking a plurality of nonlinear resistors; a cylinder-shaped insulating container housing the internal surge arrester element and housing an insulating gas therein; a high voltage side conductor provided on an end portion of the insulation container to form an exposed surface that is exposed to the inside of the insulation container and electrically connected to the internal surge arrester member; and an insulating resin layer covering at least a boundary portion between the exposed surface of the high voltage laterak conductor and an inner surface of the insulating container.
