Abstract
The utility model discloses a phase column for a vacuum-switch combined electrical apparatus, comprising a switching element, a fuse, an embedded connecting element and an insulating base. The embedded connecting element is connected with the switching element and the fuse. The insulating base is molded outside the switching element in a sealing way, the fuse and the embedded connecting element by means of integrally pouring epoxy resin. As an insulation cylinder of the fuse is poured together with the outer insulation of the switching element (the insulation base), the phase column has the advantages that: 1. the volume of the phase column can be as small as possible, and the vacuum switch-fuse combined electrical apparatus can be smaller; 2. the accuracy of the overall dimension is improved and the assembly errors can be decreased; 3. the fuse is simply installed; and 4. the effects of energy and time saving as well as environment protection are achieved.
