Therefore, the plating applied to the surface of the contact portion of the fixed conductor that comes into contact with the spring contact is worn. Since wear delamination progresses for each opening and closing operation, the conductor base material is finally exposed. If the base material of the conductor is exposed, the contact state of the contact changes every opening and closing operation, and the contact resistance between the fixed conductor and the spring contact becomes unstable and gradually increases, leading to a rise in the temperature of the contact portion. There is a risk. In other words, suppressing the wear of the plating improves the reliability of the contact portion and thus the switchgear itself.

- the abrasion peeling that occurs at the tip of the bus-side fixed conductor 18A proceeds to the stop position of the spring contact 22A on the inner surface of the bus-side fixed conductor 18A. Since this wear peeling gradually progresses by sliding of the bus-side fixed conductor 18A and the spring contact 22A, that is, by repeating the opening and closing operation, the base material of the bus-side fixed conductor 18A is finally exposed, and the bus-side fixed There is a possibility that the contact resistance between the conductor 18A and the spring contact 22A will increase.

Wear delamination can be suppressed. Therefore, it is possible to maintain a stable low contact resistance for a long period of time, and to improve the reliability, such as preventing a temperature rise of the energization part.

As a method of change, when the movable conductor slides inside the fixed conductor, it is sufficient that the diameter in a substantially vertical direction is consistently reduced from the protruding portion toward the contact portion. When the movable conductor slides, it may be a direction that increases consistently.

While achieving the effect of the first embodiment, the frictional force immediately after the spring contact 22A contacts the front end of the bus-side fixed conductor 28A can also be suppressed.
- the portion where the bus-side fixed conductor 28A and the movable conductor 20 slide is described as a representative, but other slides such as the ground disconnection portion intermediate fixed conductor and the ground disconnection portion ground fixed conductor are described. The same applies to conductors involved in movement, without needing to be redundantly described.
