摘要： A transformer apparatus whose transformer (14) and a plurality of circuit-breakers (12, 18) are individually accommodated in a plurality of different casings (20, 22, 24). The casings are stacked one above each other in a plurality of stages with gaps (48) between two subsequent casings and between the casing (24) in the lowermost stage and the floor surface (46) on which the apparatus is mounted. When a specific casing (22) among the plurality of casings which is in an intermediate stage is to be dismounted, support columns (52) are disposed on the outside of the specific casing with their respective ends inserted into the relevant gaps (48) in such a manner that the support columns support the upper subsequent casing (20), thereby enabling the intermediate casing (22) to be dismounted and remounted.

摘要： A switchboard (1) comprises a plurality of bus bars (10, 10a, 10b) as a power source, a plurality of electrical equipments (9, 15, 16, 17) and guide rails (110, 120) carrying at least one of said electrical equipments (9). A plurality of switchboard unit casings (3), which accommodate the respective electrical equipments (9, 15, 16, 17), are attached to a common bus bar casing (2), which accommodates the bus bars (10, 10a, 10b), while permitting detachment therefrom. The bus bars (10, 10a, 10b) extend horizontally and are disposed in the vertical direction with predetermined intervals. At least one of the switchboard unit casings (11) accommodates a plurality of vacuum circuit breakers (9) and a plurality of load side conductors (51) to be connected to load side cables (61), first disconnecting switch units (31) interconnecting the bus bars (10, 10a, 10b) and the vacuum circuit breakers (9), and second disconnecting switch units (34) interconnecting the vacuum circuit breakers (9) and the load side conductors (51). The contact moving axes of the respective vacuum circuit breakers (9) extend horizontally and in the depth direction of the switchboard unit casing (11), which direction is perpendicular to the extending direction of the bus bars (10, 10a, 10b). The vacuum circuit breakers (9) are disposed vertically with predetermined intervals, and the load side conductors (51) extend perpendicularly to the contact moving axes of the vacuum circuit breakers (9) and in the vertical direction.
