A package panel switchgear comprising; a load switch a power fuse which is connected to a secondary side of the load switch; an instrument transformer which is connected to a secondary side of the power fuse; a potential transformer which is connected to a secondary side of the instrument transformer; a vacuum breaker which is connected to a secondary side of the potential transformer is disclosed. The load switch, the power fuse, the instrument transformer, the potential transformer, and the vacuum breaker are connected by a circular bus bar and package panel switchgear is formed of one panel including a first section and a second section. The load switch, the instrument transformer, and the vacuum breaker are located on the first section and the circular bus bar is located on the second section. The second section is in the air break state and the load switch is connected to a bushing for the load switch which is installed on a boundary aspect of the first and second sections. The instrument transformer is connected to a bushing for a transformer which is installed on the boundary aspect of the first and second sections. The vacuum breaker is connected to a bushing for the vacuum breaker which is installed on the boundary aspect of the first and second sections. |
