The present invention relates to a vacuum interrupter including a wrap type seal cup. The present invention provides the vacuum interrupter which includes an insulation container which is formed with a tube shape to form the lateral side of a vacuum container and the wrap type seal cup which is combined with the end of the insulation container to form the upper side or the lower side of the vacuum container. The wrap type seal cup includes a cover part which covers the end of the insulation container and a wrapping protrusion part which protrudes from the cover part and surrounds the outer circumference of the end of the insulation container. The present invention improves insulation resistance against an external insulation breakdown and improves insulation resistance against an internal insulation breakdown. In the vacuum interrupter including the wrap type seal cup according to the present invention, the insulation container is made of silicon materials and the wrap type seal cup is made of OFC materials. |
