関する。DETAILED DESCRIPTION OF THE INVENTION A drawer-type unit is inserted into a bus bar provided in a switchgear cabinet and is electrically connected to the bus bar portion of the connection point, and a wire is attached to the bus bar portion of the connection point as the unit is inserted. A busbar insulating shutter is provided that is pushed up from below and moved by at least one wedge-shaped busbar insulating shutter opening/closing piece to expose the connection point, and when the drawer-type unit is pulled out, the busbar insulating shutter closes the busbar. This invention relates to a switchgear that covers connection points.
