Claims

[Claims for Utility Model Registration] At least a cubicle, a switching device disposed within the cubicle and configuring a predetermined power receiving circuit, and an electric power supply and demand instrument transformer connected to a main circuit conductor within the cubicle. In the closed power receiving equipment, a cubicle-side connection terminal connected to a portion of the main circuit conductor in the cubicle to which the electric power supply and demand instrument transformer is connected is led out from a side surface of the cubicle, and the electric power supply and demand The instrument transformer is provided with a transformer-side connection terminal that is removably connected to the cubicle-side connection terminal from a horizontal direction, and the power supply and demand instrument transformer is located outside the cubicle and has a substantially horizontal base. A closed type power receiving equipment, characterized in that moving wheels that roll on the base are attached to the lower part of the electric power supply and demand meter transformer.
