PURPOSE:To eliminate the need of a distribution board exclusively used for a transformer so as to improve the workability by fixing the transformer on a channel base in the space surrounded by a breaker board and distribution board. CONSTITUTION:After arranging a breaker board 2 and distribution board 3 in a U-shape on a channel base 1, a control line duct 4 is assembled from the top. Then, a house transformer 8 covered with a grounding metal is fixed on the base 1 in the space surrounded by the base 1, back panel 5 of the breaker board 2, back panel 6 of the distribution board 3, and the partition 7 of the duct 4. Therefore, the cost of a metallic enclosed type switchgear can be reduced, because no exclusive enclosure is required for housing the transformer 8. In addition, no dismantling work is required at the factory nor restoring work is required on the spot, because the switchgear can be transformed in one body. |
