2 and is fixed to the floor plate 101c via the base 2 (FIG. 12). Subsequently, an attachment member such as an L-shaped frame 104 is fixed to a predetermined vertical column 103 by welding or a bolt. Then, each of the storage devices and the internal components are sequentially fixed to predetermined positions of the closed box 101 by welding or bolts.
The height of the closed switchboard is, for example, 2300 mm, and storage devices and protection plates such as the upper cradle 2, the upper load-side branch conductor 5, and the instrument current transformer 8, which are arranged above a predetermined height. In the mounting operation of the internal components such as 106, the operator performs the mounting operation using a stepladder or a work table. In addition, the weight of the cradle 2 and the current transformer for instrument 8 is, for example, 30 kg and 15 kg, and when mounting a heavy object exceeding a predetermined weight such as the cradle 2 and the current transformer for instrument 8, the worker must use a crane or Mounting work is performed using a cart or with a plurality of workers lifting these heavy objects. Here, the mounting operation of the upper cradle 2 will be described with reference to FIG. FIG. 13 shows FIG.
1 is a cross section XIII-XIII. In the figure, first, both ends of two L-shaped frames 104 are connected to the floor plate 1 of the vertical column 103.
Each is fixed to a predetermined height from 01c by welding. After the upper cradle 2 is lifted by a crane and placed at a predetermined position on the L-shaped frame 104, the upper cradle 2 is attached to the L-shaped frame 104 by bolts. In the mounting operation of the upper cradle 2, the operator performs the mounting operation on a stepladder or a work table. After the upper cradle 2 is attached to the L-shaped frame 104, the four covers 109 are fixed to the upper cradle 2 and the vertical columns 103 by welding or bolts as shown in FIG.
01 is divided into a control compartment 12, a busbar compartment 10, and a cable compartment 11.

Therefore, it takes time to locate and attach the storage device and the internal components, and it has been difficult to reduce the assembly time of the closed switchboard. In addition, since the floor plate 101c of the closed box 101 is formed of only one metal plate,
When the closed switchboard is operated by, for example, a roller pulling operation using a roller or the like, the storage device such as the draw-out circuit breaker 1 is removed from the closed box 101 and the closed switchboard floor plate 101c is not provided with the storage device. It was necessary to prevent the load from being applied. Further, in the mounting work of the storage device and the internal components arranged above the predetermined height, the operator has to perform a high place work using a stepladder or a work table. In addition, when attaching a heavy object exceeding a predetermined weight, it is necessary for the operator to perform heavy lifting work to lift the heavy object.

ンパクトにできる。Next, a method for assembling a closed switchboard using the closed box of the present invention will be described below. As described above, in the closed box 100 of the present invention, the frame to which the storage device and the internal components are attached is divided into the first, second and third frames 30, 40 and 50. ing. Therefore, in the method for assembling the closed switchboard according to the present invention, the work of attaching the storage device and the internal components to the first, second, and third frames 30, 40, and 50 can be performed in parallel. Here, an operation of attaching the cradle 2 to the attachment reference member 44 will be described with reference to FIG. FIG. 5 is a perspective view showing a structure in which the cradle 2 is attached to the attachment reference member 44. In the figure, first, the attachment reference member 44 is horizontally arranged so as to be parallel to the installation surface of the closed switchboard. Next, after the cradle 2 is lifted by a crane and placed at a predetermined position on the attachment reference member 44, the cradle 2 is attached to the attachment reference member 44 by bolts. The L-shaped frames 41a, 41b, 41c, and 41d of the second frame 40 shown in FIG. 2 are fixed to both ends of the attachment reference member 44 in the left and right directions as viewed in FIG. Then, the L-shaped frames 41a, 4
One end of each of 1b, 41c, and 41d is arranged on a cart or the like, and the attachment reference member 44 is horizontally arranged at a predetermined height so that an operator can easily perform the attachment work (not shown). Thus, the positioning operation and the mounting operation of the cradle 2 to the second outer frame 40 are facilitated. In addition, the worker can perform the mounting work without performing a high place work using a stepladder or a work table. Further, the operator can perform the mounting work without performing the heavy lifting work of lifting the heavy cradle 2. Similarly, other storage devices and internal components are attached to the second frame 40. First, in FIG. 1, a front door 10 than the mounting reference member 44
Frame 70 of L-shaped disposed 0a side, the internal components such as upper and lower protective plates 72 and the partition cover 73, the respective from the upper on the paper of FIG. 5 of the mounting reference member 44 disposed horizontally 2 is fixed to the frame 40.
After that, the second frame 40 is rotated by 180 degrees (the state of FIG. 5 is rotated by 180 degrees). And FIG.
, The back cover 100 d
The internal components such as the busbar 3, the current transformer 8 for the instrument, and the cover 74, which are arranged on the side, are respectively located on the second side from the lower side on the paper surface of FIG. Is fixed to the frame body 40. By rotating the second frame 40 provided with the attachment reference member 44 by 180 degrees as described above,
Since the storage device and the internal component members are attached to the mounting reference member 44 from above the mounting reference member 44, the positioning operation of the storage device and the internal component members can be facilitated, and high-place work and heavy-strength work can be performed. The storage device and the internal components can be attached to the attachment reference member 44 without the need. The internal components such as the L-shaped frame 70, the upper and lower protection plates 72, and the partition cover 73 disposed on the front door 100a side from the mounting reference member 44 are mounted on the horizontally mounted mounting reference member 44. After that,
By rotating the second frame 40 by 180 degrees, the mounting reference member 44 is rotated.
The assembling method for attaching the internal components such as the cover 74 and the storage devices such as the busbar 3 and the current transformer 8 disposed on the back cover 100d side to the attachment reference member 44 has been described. Are rotated by 180 degrees, the L-shaped frames 41a, 41b, 41 of the second frame 40 are
The height of the carriage on which one end of each of c and 41d is placed is increased, and the inside of the storage device such as the busbar 3 and the current transformer 8 for the instrument and the cover 74 and the like disposed on the side of the back cover 100d from the mounting reference member 44 The constituent members may be mounted from below the mounting reference member 44 horizontally arranged on the paper surface of FIG. As is apparent from the drawings such as FIG. 1, the attachment reference member 44 is provided on the boundary surface between the breaker compartment 9 and the busbar compartment 10. Also,
Thereby, for example, the work of positioning and attaching the cradle 2 forming the circuit breaker compartment 9 to the second outer frame 40 becomes easy, and the partition structure between the circuit breaker compartment 9 and the busbar compartment 10 can be made compact. .
