従来の配電盤（キュービクル）を屋内へ搬入する場合、屋内の搬入口に因るが、一般に搬入口は縦幅は大きいが、横幅は小さい。そのため、搬入口に制限がある場合は、搬入口を壊したり窓から搬入したりしなければならない。また、高層ビルなど搬入先が高い場所の場合は、クレーン等で吊り上げて窓枠を外して搬入するなど、相当な工数が必要とされる。 When carrying a conventional switchboard (cubicle) indoors, although it depends on the indoor entrance, the entrance generally has a large vertical width but a small lateral width. For this reason, when there is a restriction on the carry-in port, the carry-in port must be broken or carried through a window. Also, in places with high destinations such as high-rise buildings, considerable man-hours are required, such as lifting with a crane or the like to remove the window frame and carrying in.

特許文献１記載の配電盤は縦方向の分割は可能であるが、横幅を考慮して屋内へ搬入する必要がある。そのため、壁、ドアの撤去や、窓など屋外からの搬入が必要となる場合がある。 Although the switchboard described in Patent Document 1 can be divided in the vertical direction, it is necessary to carry it indoors in consideration of the width. Therefore, it may be necessary to remove walls and doors or carry in from outside such as windows.

The power receiving panel 100a includes a high voltage side device, the low voltage panel 100b includes a low voltage side device, and the transformer panel 100c includes a transformer that converts the voltage to a low voltage. 1 is composed of three panels, but the number of the panels is not limited to this. For example, the panels may be composed of one or two panels.

従来の配電盤を屋内へ搬入する場合、配電盤の幅に比べて搬入口の幅に制限があると搬入することができない。この場合は、搬入口を壊して、または外からクレーン等を用いて窓から搬入しなければならず、工数が掛かる。 When carrying in the conventional switchboard indoors, if there is a restriction | limiting in the width | variety of an entrance compared with the width | variety of a switchboard, it cannot carry in. In this case, it is necessary to break the carry-in port or carry in from the window using a crane or the like from the outside, which takes man-hours.

本実施例では、配電盤の筐体を縦横に分割してユニットとし、ユニットに互いに組み合わさる凹凸等をから成る簡易組立て構造を備えることで、配電盤の搬入、組み立てを容易にする構造を提案する。 The present embodiment proposes a structure that makes it easy to carry in and assemble the switchboard by providing a simple assembly structure in which the casing of the switchboard is divided vertically and horizontally to form a unit and the unit is provided with unevenness combined with each other.

図２に、実施例１の配電盤の組立斜視図を示す。また、図３Ａに第１ユニット（下段ユニット）の斜視図を、図３Ｂに第２ユニット（上段ユニット）の斜視図を示す。 FIG. 2 shows an assembly perspective view of the switchboard of the first embodiment. 3A is a perspective view of the first unit (lower unit), and FIG. 3B is a perspective view of the second unit (upper unit).

図２に示すように、本実施例では、配電盤の筐体１を縦横に分割する。図の例では、縦方向に２分割、横方向に３分割している。分割ユニットは、互換性のある２種類のユニットとする。図３Ａに示される第１のユニット（下部ユニット）２は、直方体形状をしており、その上面には奥行き方向に直線状の凹部から成る２つのレール構造１１を備えている。また、その右側面には、前部および後部に高さ方向に延びる、両端が閉じた直線状の位置決め凹部１５を備えている。なお、図３Ａには示されていないが、左側面には、位置決め凹部１５と反対の位置に両端が閉じた直線状の位置決め凸部１６を備えている。図３Ｂに示される第２のユニット（上部ユニット）３も、直方体形状をしており、その下面には、奥行き方向に直線状の凸部から成る２つのレール構造１２を備えている。また、その右側面には、前部および後部に高さ方向に延びる、両端が閉じた直線状の位置決め凸部１６を備えている。なお、図３Ｂには示されていないが、左側面には、位置決め凸部１６と反対の位置に両端が閉じた直線状の位置決め凹部１５を備えている。第１ユニットの直線状の凹部から成るレール構造１１に、第２ユニットの直線状の凸部から成るレール構造１２を差し込むことにより、第２ユニット３が奥行き方向にスライド可能となる。第１のユニットと第２のユニットの高さ寸法は、第１ユニット２の高さが第２ユニット３よりも大きく設定されているが、同じ高さでも、また、第２ユニット３の高さを第１ユニット２の高さよりも大きくしても良い。 As shown in FIG. 2, in this embodiment, the casing 1 of the switchboard is divided vertically and horizontally. In the example shown in the figure, it is divided into two parts in the vertical direction and three parts in the horizontal direction. The division unit is assumed to be two types of compatible units. The first unit (lower unit) 2 shown in FIG. 3A has a rectangular parallelepiped shape, and has two rail structures 11 formed of linear recesses in the depth direction on the upper surface thereof. Moreover, the right side surface is provided with a linear positioning recess 15 extending in the height direction at the front and rear and closed at both ends. Although not shown in FIG. 3A, a linear positioning convex portion 16 having both ends closed at a position opposite to the positioning concave portion 15 is provided on the left side surface. The second unit (upper unit) 3 shown in FIG. 3B also has a rectangular parallelepiped shape, and has two rail structures 12 formed of linear convex portions in the depth direction on the lower surface thereof. In addition, the right side surface includes linear positioning convex portions 16 extending in the height direction at the front and rear portions and closed at both ends. Although not shown in FIG. 3B, the left side surface includes a linear positioning recess 15 whose both ends are closed at a position opposite to the positioning protrusion 16. The second unit 3 can be slid in the depth direction by inserting the rail structure 12 including the linear convex portion of the second unit into the rail structure 11 including the linear concave portion of the first unit. As for the height dimension of the first unit and the second unit, the height of the first unit 2 is set to be larger than that of the second unit 3, but the height of the second unit 3 is also the same. May be larger than the height of the first unit 2.

図３Ｃに、第１のユニット２と第２のユニット３とを上下に組み合わせた上下連結ユニット構造４を示す。第１のユニット２の上面の、直線状の凹部から成るレール構造１１に、第２のユニット３の下面の、直線状の凸部から成るレール構造１２を嵌め合わせ、レール構造により、第２のユニット３を前後に移動させて、第１のユニットと第２のユニットの位置合わせを行う。上段の第２のユニット３の下部にある凸部から成るレール構造１２を、下段の第１ユニット２の上部にある凹部から成るレール構造１１に差し込むことで、上下のユニット間の連結作業を容易とし、組立て作業効率を上げることができる。また、下段の第１ユニット２に上段の第２ユニット３を差し込む際に、凸部の接触面にグリス等を塗布することで容易に差し込むことが可能となり、挿入時に発生する恐れのある傷や塗装剥離の発生率を低減することも可能となる。 FIG. 3C shows an upper and lower connection unit structure 4 in which the first unit 2 and the second unit 3 are vertically combined. The rail structure 11 consisting of a straight convex part on the lower surface of the second unit 3 is fitted to the rail structure 11 consisting of a linear concave part on the upper surface of the first unit 2, and the second The unit 3 is moved back and forth to align the first unit and the second unit. By connecting the rail structure 12 consisting of the convex part at the lower part of the upper second unit 3 to the rail structure 11 consisting of the concave part at the upper part of the lower first unit 2, it is easy to connect the upper and lower units. As a result, the assembly work efficiency can be increased. Further, when the upper second unit 3 is inserted into the lower first unit 2, it can be easily inserted by applying grease or the like to the contact surface of the convex portion, and scratches or It is also possible to reduce the rate of occurrence of paint peeling.

図３Ｄに、第１ユニット２と第２ユニット３を横方向に組み合わせた左右連結ユニット構造５を示す。図では見えないが、第１ユニット２の右側面に設けた位置決め凹部１５に、第２ユニット３の左側面に設けた位置決め凸部１６が嵌まり込み、第１ユニット２と第２ユニット３とが位置決めされる。このように、分割された第１ユニットおよび第２ユニットには左右の側面に凹凸構造を備えているため、ユニット組立て時にはユニット同士を位置決めして、横から嵌め込み固定することができる。ユニット左右の凹凸は凹み加工を行った板金部品を用いればよい。 FIG. 3D shows a left and right connecting unit structure 5 in which the first unit 2 and the second unit 3 are combined in the horizontal direction. Although not visible in the figure, the positioning convex portion 16 provided on the left side surface of the second unit 3 is fitted into the positioning concave portion 15 provided on the right side surface of the first unit 2, and the first unit 2, the second unit 3, Is positioned. Thus, since the divided first unit and second unit are provided with uneven structures on the left and right side surfaces, the units can be positioned and fitted and fixed from the side during unit assembly. For the unevenness on the left and right sides of the unit, a sheet metal part subjected to dent processing may be used.

図３Ｅに、図３Ｃの上下連結構造と図３Ｄの左右連結構造を組み合わせた上下左右連結ユニット構造６の正面図を示す。また、図３Ｆに、上下左右連結ユニット構造６の斜視図を示す。図に示すように、連結ユニット構造では、左側では第１ユニット２を下段とし、第２ユニット３を上段に配置する。そして、右側では第２ユニット３を下段とし、第１ユニット２を上段に配置する。図３Ｃに示す上下連結ユニット４と図３Ｄに示す左右連結ユニット５を組み合わせることにより、前後の揺れまたは衝撃に対して強度を増すことができる。第１ユニットと第２ユニットの高さ寸法を変えることにより、分割箇所の位置がずれて段差状になるため、前後の揺れまたは衝撃にも強度が増し、より安定化することができる。 FIG. 3E shows a front view of an upper / lower left / right connection unit structure 6 in which the upper / lower connection structure of FIG. 3C and the left / right connection structure of FIG. 3D are combined. FIG. 3F shows a perspective view of the upper / lower / left / right connecting unit structure 6. As shown in the figure, in the connection unit structure, on the left side, the first unit 2 is arranged on the lower stage, and the second unit 3 is arranged on the upper stage. On the right side, the second unit 3 is arranged at the lower stage, and the first unit 2 is arranged at the upper stage. By combining the upper and lower connecting unit 4 shown in FIG. 3C and the left and right connecting unit 5 shown in FIG. 3D, the strength can be increased against forward and backward shaking or impact. By changing the height dimensions of the first unit and the second unit, the positions of the divided portions are shifted to form a stepped shape, so that the strength is increased even when the front and rear shakes or impacts, and the stability can be further stabilized.

FIG. 5 is a front sectional view of the casing 1 of the switchboard of the first embodiment shown in FIG. FIG. 5 is a cross-sectional view of the unit at the positions of the positioning concave portion 15 and the positioning convex portion 16.

図に示すように、第１ユニット２と第２ユニット３とが、上下に２つ、左右に３つ組み合わされている。そして、左右方向には、第１ユニットおよび第２ユニットの側面に設けた位置決め凹部に位置決め凸部を嵌め合わせることにより、位置決めをすることができる。また、第１ユニットの上面に設けた直線状の凹部から成るレール構造１１に、第２のユニット３の下面に設けた直線状の凸部から成るレール構造１２を差し込むことにより、上段のユニットをスライドさせて取り付けることができる。ドア７は、上下連結ユニット４に１枚ずつ取り付けられている。なお、実施例１では、配電盤の筐体１を、上下２段および左右３つに分割したが、図３Ｅおよび図３Ｆに示されるように、上下２段および左右２つに分割しても良いし、上下を３段以上或いは左右を４つ以上に分割しても良い。 As shown in the figure, the first unit 2 and the second unit 3 are combined in two vertically and three horizontally. And in the left-right direction, it can position by fitting a positioning convex part to the positioning recessed part provided in the side surface of a 1st unit and a 2nd unit. In addition, by inserting the rail structure 12 including the linear convex portion provided on the lower surface of the second unit 3 into the rail structure 11 including the linear concave portion provided on the upper surface of the first unit, the upper unit is Can be installed by sliding. One door 7 is attached to each of the upper and lower connecting units 4. In the first embodiment, the casing 1 of the switchboard is divided into two upper and lower stages and three left and right. However, as shown in FIGS. 3E and 3F, it may be divided into two upper and lower stages and two left and right. However, the upper and lower sides may be divided into three or more stages or the left and right sides may be divided into four or more.
