うにしたことを特徴とする真空ヒユーズ。 A vacuum fuse is constructed by arranging opposing electrodes in a vacuum container and connecting a fusible conductor between the electrodes, in which ceramic disks are bonded to both ends of a cylindrical envelope made of a metal that can be bonded to ceramic. ,
Moreover, the conductive rod supporting the electrode and the ceramic disk arranged facing each other are provided with a metal flange so that an insulating distance can be maintained even if conductive substances are attached to the inner surface of the ceramic due to the arc generated during interruption. 1. A vacuum fuse characterized in that the conductive rod has a structure in which the conductive rod is connected to an external conductor, and the entire fuse tube except for the external conductor connection surface of the conductive rod is covered with an insulating resin.
