Power switching device

摘要

Disclosed is a power switching device provided with: an insertion hole (109a) which is supported by a stationary-side insulating support (105), is formed on a stationary-side contact case (109) for securing the stationary-side of a vacuum valve (110), has a larger inner diameter than the outer diameter of the vacuum valve (110) so that the vacuum valve (110) can be inserted in the horizontal direction, and is inserted and disposed with the stationary-side edge portion of the vacuum valve (110); and a stationary-side connecting conductor (113) which is attached to the stationary-side contact case (109) and which is connected to the stationary-side edge portion of the vacuum valve (110).
