Abstract:
A switching mechanism for a tap selector of an on-load tap changer according to one embodiment of the present invention comprises a fixed part, a movable part, a biasing member, and a guide. The fixed part has a fixed contact point. The fixed part is formed in an annular shape. The movable part has a movable contact point that can be connected to the fixed contact point. The movable part is capable of moving in the circumferential direction of the fixed part. The biasing member biases the movable part toward the fixed part. The guide is provided to the fixed part. The guide guides the movable part between a connection location at which the movable contact point comes into contact with the fixed contact point and a non-connection location at which the movable contact point is out of contact with the fixed contact point.
