Exposed surface) is exposed outside the cover 8.

第１天板82は、長方形の金属板からなり、トランス４及びトランス４の取付部材を上方から覆うものである。第２天板83は、長方形の金属板からなり、断路器５及び断路器５の取付部材を上方から覆うものである。第１前板80の上端が第１天板82の前端と連結され、第１天板82の後端が第２前板81の下端と連結され、第２前板81の上端が第２天板83の前端と連結されている。ただし、第１天板82並びに第２天板83は、前方に向かって下向きに傾斜している。 The first top plate 82 is made of a rectangular metal plate and covers the transformer 4 and the mounting member of the transformer 4 from above. The 2nd top plate 83 consists of a rectangular metal plate, and covers the disconnect device 5 and the attachment member of the disconnect device 5 from upper direction. The upper end of the first front plate 80 is connected to the front end of the first top plate 82, the rear end of the first top plate 82 is connected to the lower end of the second front plate 81, and the upper end of the second front plate 81 is connected to the second top plate. The front end of the plate 83 is connected. However, the first top plate 82 and the second top plate 83 are inclined downward toward the front.

左側板は、大きさの異なる２つの台形をつなぎ合わせた形状であって、第１前板80、第２前板81、第１天板82、第２天板83の左端と連結されている。また、右側板は、左側板と同一形状であって、第１前板80、第２前板81、第１天板82、第２天板83の右端と連結されている。 The left side plate has a shape obtained by connecting two trapezoids having different sizes, and is connected to the left ends of the first front plate 80, the second front plate 81, the first top plate 82, and the second top plate 83. . The right side plate has the same shape as the left side plate, and is connected to the right ends of the first front plate 80, the second front plate 81, the first top plate 82, and the second top plate 83.

上述のように構成されるカバー８は、左側板及び右側板の後端が本体２の背板に当たり、左側板及び右側板の下端と第１前板80の下端が本体２の底面に当たるようにして本体２内に収納される(図３及び図４参照)。そして、本体２の前面下部に設けられている一対の固定片24に第１前板80がねじ止めされ、且つ支持部材７の一対のカバー固定片715に第２前板81がねじ止めされることによって、カバー８が本体２に固定される。ただし、第２天板83の後端と本体２の背板との間には、微小な隙間が形成される(図４参照)。 In the cover 8 configured as described above, the rear ends of the left and right plates touch the back plate of the main body 2, and the lower ends of the left and right plates and the lower end of the first front plate 80 touch the bottom surface of the main body 2. And stored in the main body 2 (see FIGS. 3 and 4). Then, the first front plate 80 is screwed to the pair of fixing pieces 24 provided at the lower front surface of the main body 2, and the second front plate 81 is screwed to the pair of cover fixing pieces 715 of the support member 7. As a result, the cover 8 is fixed to the main body 2. However, a minute gap is formed between the rear end of the second top plate 83 and the back plate of the main body 2 (see FIG. 4).

蓋体３は、図５に示すように本体２の前面開口を覆う前パネル30、前パネル30の上端及び下端からそれぞれ後方に突出する上側壁31及び下側壁32を有している。なお、前パネル30の左右両端は円弧状に湾曲し、上下両端で上側壁31及び下側壁32と繋がっている。 As shown in FIG. 5, the lid 3 has a front panel 30 that covers the front opening of the main body 2, and an upper side wall 31 and a lower side wall 32 that protrude rearward from the upper and lower ends of the front panel 30. The left and right ends of the front panel 30 are curved in an arc shape, and are connected to the upper side wall 31 and the lower side wall 32 at the upper and lower ends.

下側壁32には、外気を導入するため、多数の通気孔320が左右方向に並べて設けられている。また、下側壁32の後端における左右両端には、鈎形の突片からなる係止部33がそれぞれ設けられている。 The lower side wall 32 is provided with a large number of ventilation holes 320 arranged in the left-right direction for introducing outside air. Further, on both left and right ends of the rear end of the lower side wall 32, locking portions 33 each having a hook-shaped projecting piece are provided.

図８に示すように、本体２の突片22の被係止部220に、下側壁32の係止部33が下から挿通される。そうすると、蓋体３は、被係止部220に係止された係止部33を支点にして、本体２の前面開口を塞ぐ位置(閉位置)と、本体２の前面開口を開放する位置(開位置)との間で回動自在に本体２に取り付けられる。そして、蓋体３は、図６及び図７に示すように閉位置において、前パネル30の上部左右両端に形成されているねじ挿通孔300に挿通されるねじ(図示せず)が、本体２の外鍔21に形成されているねじ孔210にねじ込まれることで本体２に固定される。したがって、蓋体３の上下左右両端で本体２にねじ止めされる場合と比較して、蓋体３を本体２に取り付ける際の作業性の向上を図ることができる。また、蓋体３の後端面に防水パッキンが設けられる場合、蓋体３の上部２箇所をねじ止めするだけで、防水パッキンが本体２前面と蓋体３の後端面との間で圧縮される。 As shown in FIG. 8, the locking portion 33 of the lower side wall 32 is inserted from below into the locked portion 220 of the protruding piece 22 of the main body 2. Then, the lid 3 uses the locking portion 33 locked to the locked portion 220 as a fulcrum to close the front opening of the main body 2 (closed position) and open the front opening of the main body 2 (closed position). (The open position) is attached to the main body 2 so as to be rotatable. As shown in FIGS. 6 and 7, the lid 3 has a screw (not shown) that is inserted into screw insertion holes 300 formed in the upper left and right ends of the front panel 30 in the closed position. It is fixed to the main body 2 by being screwed into a screw hole 210 formed in the outer casing 21. Therefore, workability when attaching the lid 3 to the main body 2 can be improved as compared with the case where the lid 3 is screwed to the main body 2 at both the upper, lower, left and right ends. Further, when the waterproof packing is provided on the rear end surface of the lid 3, the waterproof packing is compressed between the front surface of the main body 2 and the rear end surface of the lid 3 only by screwing the two upper portions of the lid 3. .

図９に示すように建物の外の地面(あるいはコンクリート製の土台など)に架台１が設置され、架台１の上に電気設備100が載置される。なお、架台１と電気設備100の収納ケース101とは、ボルト及びナットを用いて強固に結合される。 As shown in FIG. 9, the gantry 1 is installed on the ground (or a concrete base or the like) outside the building, and the electrical equipment 100 is placed on the gantry 1. Note that the gantry 1 and the storage case 101 of the electric equipment 100 are firmly coupled using bolts and nuts.

上述のように本実施形態の架台１は、配電系機器４，５が取り付けられる取付部材を備え、本体２の天面には配電系機器４，５と電気設備100を電気的に接続するための電線が挿通される挿通孔(窓孔23)が設けられている。そのため、本体２内の空いたスペースを有効活用することにより、配電系機器４，５の設置スペースの削減を図ることができる。 As described above, the gantry 1 of the present embodiment includes an attachment member to which the power distribution system devices 4 and 5 are attached, and electrically connects the power distribution system devices 4 and 5 and the electrical equipment 100 to the top surface of the main body 2. An insertion hole (window hole 23) through which the electric wire is inserted is provided. Therefore, by effectively utilizing the vacant space in the main body 2, it is possible to reduce the installation space for the power distribution system devices 4 and 5.

また、蓋体３の下側壁32に設けられる通気孔320から導入される外気(空気)が、本体２の上面に開口する窓孔23から、電気設備100の収納ケース101の底面に設けられているスリット105を通して収納ケース101内に導入される。そのため、架台１の上に載置された状態においても、電気設備100の放熱性能が阻害されることがない。 In addition, outside air (air) introduced from a vent hole 320 provided in the lower side wall 32 of the lid 3 is provided on the bottom surface of the storage case 101 of the electrical equipment 100 from the window hole 23 opened on the top surface of the main body 2. It is introduced into the storage case 101 through the slit 105. Therefore, even in the state of being placed on the gantry 1, the heat dissipation performance of the electrical equipment 100 is not hindered.

ここで、直接若しくは電気設備100の収納ケース101内を伝って、窓孔23から本体２内へ雨水が浸入する場合がある。本実施形態では、本体２内の配電系機器４，５がカバー８で覆われており、且つ本体２の天面に対向するカバー８の第１天板82及び第２天板83が下向きに傾斜する傾斜面となっている。そのため、窓孔23から浸入した雨水は、第１天板82又は第２天板83を伝って本体２の底面へ落ちるので、配電系機器４，５に雨水が掛かることがなく、且つカバー８の上に雨水が溜まることもない。しかも、蓋体３の通気孔320から本体２の窓孔23に至る空気の流路がカバー８で塞がれることがないため、電気設備100の放熱性が阻害されることもない。なお、本体２の底面へ落ちた雨水は、本体２の前面下端部に設けられている排水溝25を通して、本体２の外に排水される。また、配電系機器４，５で発する熱は、第２天板83と本体２の背板との間に設けられた隙間を通してカバー８の外に放熱される。ただし、前記隙間は、上下方向から見て本体２の天面の投影範囲内に隠れているので(図３(ｂ)参照)、雨水が浸入する可能性は極めて低い。 Here, rainwater may enter the main body 2 from the window hole 23 directly or through the storage case 101 of the electrical equipment 100. In the present embodiment, the distribution system devices 4 and 5 in the main body 2 are covered with the cover 8, and the first top plate 82 and the second top plate 83 of the cover 8 facing the top surface of the main body 2 face downward. It has an inclined surface. Therefore, rainwater that has entered from the window hole 23 passes through the first top plate 82 or the second top plate 83 and falls to the bottom surface of the main body 2, so that the rainwater does not splash on the power distribution equipment 4, 5 and the cover 8. Rainwater does not collect on the top. Moreover, since the air flow path from the vent hole 320 of the lid 3 to the window hole 23 of the main body 2 is not blocked by the cover 8, the heat dissipation of the electrical equipment 100 is not hindered. Note that rainwater that has fallen to the bottom surface of the main body 2 is drained out of the main body 2 through a drainage groove 25 provided at the lower end of the front surface of the main body 2. Further, the heat generated by the power distribution system devices 4 and 5 is radiated out of the cover 8 through a gap provided between the second top plate 83 and the back plate of the main body 2. However, since the gap is hidden within the projection range of the top surface of the main body 2 when viewed from above and below (see FIG. 3B), the possibility of rainwater entering is extremely low.

本実施形態では、本体２内に収納される配電系機器としてトランス４と断路器５を例示したが、これに限定する趣旨ではなく、トランス４及び断路器５以外の配電系機器が本体２内に収納されてもよい。ただし、水害によって本体２内に多量の水が浸入した場合、配電系機器からの漏電などが生じる虞がある。この場合、配電系機器が交流配電系の機器(トランス４など)であれば、電力系統側のブレーカ(分電盤の主幹ブレーカなど)で電路が遮断されて配電系機器への通電も停止するので、漏電などの不具合が生じることはない。 In the present embodiment, the transformer 4 and the disconnector 5 are illustrated as the distribution system devices accommodated in the main body 2. However, the present invention is not limited to this, and the distribution system devices other than the transformer 4 and the disconnector 5 are included in the main body 2. It may be stored in. However, when a large amount of water intrudes into the main body 2 due to water damage, there is a risk of leakage from the distribution system equipment. In this case, if the distribution device is an AC distribution device (transformer 4 or the like), the circuit is cut off by the power system breaker (such as the main breaker of the distribution board), and the power supply to the distribution device is also stopped. So there will be no problems such as leakage.
