のとするおそれがある。 In general, a vacuum switch consists of a vacuum container made by closing both ends of an insulating tube made of glass or ceramic with end plates made of metal, and a pair of electrode rods with contacts at the inner ends inside the vacuum container. It is constructed by introducing relatively freely approaching and separating. However, in recent years, as it is planned to increase the insulation capacity of vacuum switches, the diameter of the contact point has inevitably been increased, and the diameter of the insulating tube has also been forced to increase. However, it is extremely difficult to manufacture a large-diameter insulating cylinder made of glass or ceramic while maintaining the dimensional accuracy of its inner and outer diameters within a specified range, and there is a risk that the vacuum switch will become extremely expensive. There is.
