Closed box of closed switchboard and method of assembling closed switchboard using the same

摘要

PURPOSE:To provide an enclosure box, for an enclosed switchboard, in which the assembly time of the enclosed switchboard can be reduced, in which a housing apparatus and an internal constitution member can be attached to the enclosed switchboard without performing a heavy-physical labor and a high-place operation and in which the structure strength of the bottom part of the enclosure box for the enclosed switchboard can be enhanced. CONSTITUTION:A floor part 20 is constituted of a floor plate 21a which is arranged in parallel with the installation face of an enclosed switchboard and of strength constitution parts 21b which are installed perpendicularly to the floor plate 21a. Frame bodies 30, 40, 50 are divided into at least two parts in the depth direction of the enclosed switchboard. A housing apparatus and an internal constitution member are fixed respectively in parallel in at least two out of the frame bodies 30, 40, 50. Thereby, the assembly time of the enclosed switchboard is reduced.
