Description

本発明は、単相三線式電路の導電バーの両側に、プラグイン端子を有する回路遮断器を接続して成る分電盤の導電バー構造に関するものである。 The present invention relates to a conductive bar structure of a distribution board in which circuit breakers having plug-in terminals are connected to both sides of a conductive bar of a single-phase three-wire circuit.

従来、図３に示すように、分電盤に組み込まれる導電バーは、Ｎ相３１、Ｌ１相３２、Ｌ２相３３の順に上から配列され、導電バーの両側にプラグイン端子３４を有する回路遮断器３５を接続していた。プラグイン端子３４は、回路遮断器３５の側面に上下に配列された凹部に端子を設けて成る。三本の導電バーを１００Ｖで使用するとき、同種の回路遮断器３５を接続すると、同じ位置に端子が設けられているため、どれも同じ相の導電バーに接続されてしまう。工事者が相間のバランスを考えて回路遮断器３５を選択し取り付けなくてはならず、作業に手間が掛かっていた。 Conventionally, as shown in FIG. 3, the conductive bars incorporated in the distribution board are arranged from the top in the order of the N phase 31, the L1 phase 32, and the L2 phase 33, and the circuit breaker has the plug-in terminals 34 on both sides of the conductive bar. Device 35 was connected. The plug-in terminal 34 is formed by providing a terminal in a concave portion arranged on the side surface of the circuit breaker 35. When three conductive bars are used at 100 V, if the same type of circuit breaker 35 is connected, since terminals are provided at the same position, all of them are connected to the same phase conductive bar. The operator had to select and install the circuit breaker 35 in consideration of the balance between the phases, and the work was troublesome.

そして、手間無くバランスよく回路遮断器が組み付けられるように、特許文献２に記載のような分岐部構造が用いられるようになった。

しかしながら、図４〜図５に示すように、特許文献２記載の分岐部構造では、複雑で、製造コストを引き上げてしまうという欠点があった。また、導電バーの、回路遮断器の端子部と接続される部分が細く、導電バーの表面積が小さいため、発熱量が多く、温度上昇しやすいという欠点があった。 However, as shown in FIGS. 4 to 5, the branch structure described in Patent Document 2 is complicated and has a drawback of increasing the manufacturing cost. In addition, since the portion of the conductive bar connected to the terminal portion of the circuit breaker is thin and the surface area of the conductive bar is small, there is a drawback that the amount of heat generation is large and the temperature is likely to rise.

そこで本発明は、簡単な構造で、施工が容易である分電盤の導電バー構造を提供することを目的とし、その構造は、最上段に板状の導電バーを配置し、中段、下段に配置する導電バーは、略Ｕ字状の板状体の略中央部に垂直部を形成し、垂直部の上下端部はそれぞれ反対側に折曲し、分電盤に組み込む場合には、導電バーを二本一組とし互いに組み合わせ、中段及び、下段の左右に配置される導電バーはそれぞれ異なる相となるようにしたことを特徴とする。 Therefore, the present invention has an object of providing a conductive bar structure of a distribution board that has a simple structure and is easy to construct. The structure includes a plate-shaped conductive bar at the uppermost stage, and a middle stage and a lower stage. The conductive bar to be arranged forms a vertical part at the substantially central part of the substantially U-shaped plate, and the upper and lower end parts of the vertical part are bent to the opposite sides, and when incorporated in the distribution board, the conductive bar The bars are combined in pairs, and the conductive bars arranged on the left and right of the middle and lower stages are in different phases.

本発明に係る分電盤の導電バー構造は、最上段に板状の導電バーを配置し、中段、下段に配置する導電バーは、略Ｕ字状の板状体の略中央部に垂直部を形成し、垂直部の上下端部はそれぞれ反対側に折曲し、分電盤に組み込む場合には、導電バーを二本一組とし互いに組み合わせ、中段及び、下段の左右に配置される導電バーはそれぞれ異なる相となるようにしたため、回路遮断器の取り付ける位置によって相が替わり、工事者が相間のバランスを特別に考慮しなくても良いので、施工の時間が大幅に短縮できる。また、導電バーは幅広く設定できるので、表面積が広く、発熱量を抑えることができる。 In the conductive bar structure of the distribution board according to the present invention, a plate-like conductive bar is arranged at the uppermost stage, and the conductive bars arranged at the middle and lower stages are perpendicular to the substantially central part of the substantially U-shaped plate-like body. When the upper and lower ends of the vertical part are bent to the opposite side and incorporated in the distribution board, the conductive bars are combined in pairs, and the conductors are arranged on the left and right of the middle and lower stages. Since the bars are in different phases, the phases change depending on the position where the circuit breaker is attached, and the builder does not need to consider the balance between the phases, so the construction time can be greatly reduced. In addition, since the conductive bar can be set widely, the surface area is large and the heat generation amount can be suppressed.

本発明に係る分電盤の導電バー構造を図１〜図２の添付図面に基いて説明する。 A conductive bar structure of a distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

分電盤は三相の導電バーから構成されている。最上段には中性のＮ相バー１が配置され、中段、下段には電圧のかかるＬ１相バー２とＬ２相バー３とが配置される。これらの導電バーの両側には、プラグイン端子を有する回路遮断器４を配列し導電バーはプラグイン端子と接続する。回路遮断器４は、プラグイン方式のもので、側面に複数の凹部５を設け、この凹部５に必要に応じて端子６を備えて構成する。１００Ｖ回路の場合には、上部５ａと下部５ｃの凹部に、２００Ｖ回路の場合には上部５ｂと中央部５ｃの凹部に端子６を備えて用いる。 The distribution board is composed of three-phase conductive bars. A neutral N-phase bar 1 is arranged in the uppermost stage, and an L1 phase bar 2 and an L2 phase bar 3 to which voltage is applied are arranged in the middle and lower stages. Circuit breakers 4 having plug-in terminals are arranged on both sides of these conductive bars, and the conductive bars are connected to the plug-in terminals. The circuit breaker 4 is of a plug-in type, and a plurality of recesses 5 are provided on the side surface, and terminals 6 are provided in the recesses 5 as necessary. In the case of a 100V circuit, terminals 6 are provided in the recesses of the upper part 5a and the lower part 5c, and in the case of a 200V circuit, terminals 6 are provided in the recesses of the upper part 5b and the central part 5c.

上段に配置されたＮ相バー１は、板状に形成されている。中段、下段に配置されるＬ１相バー２とＬ２相バー３は、同形状のもの二本一組で構成する。その形状は、Ｌ１相バー２、Ｌ２相バー３それぞれ略Ｕ字状の板の中央部分に折曲形成により、垂直部２ａ、３ａを設ける。垂直部２ａ、３ａの両端は、それぞれ反対側に折曲し端子接続部２ｂ、３ｂを形成する。Ｌ１相バー２とＬ２相バー３を配列した時、垂直部２ａ、３ａを挟んで上下左右に隣接する端子接続部２ｂ、３ｂは異なる相が配置される。例えば、中段右側がＬ１相バー２の端子接続部２ｂとすると、Ｌ１相バー２から垂直部２ａを挟んだ反対側の端子接続部２ｂは、下段左側である。また中段左側のＬ２相バー３の端子接続部３ｂから垂直部３ａを挟んだ反対側の端子接続部３ｂは下段右側である。 The N-phase bar 1 arranged in the upper stage is formed in a plate shape. The L1 phase bar 2 and the L2 phase bar 3 arranged in the middle and lower stages are composed of a pair of the same shape. The L1 phase bar 2 and the L2 phase bar 3 are provided with vertical portions 2a and 3a by bending at the center portions of the substantially U-shaped plates, respectively. Both ends of the vertical portions 2a and 3a are bent to the opposite sides to form terminal connection portions 2b and 3b. When the L1 phase bar 2 and the L2 phase bar 3 are arranged, different phases are arranged in the terminal connection portions 2b and 3b adjacent vertically and horizontally with the vertical portions 2a and 3a interposed therebetween. For example, if the right side of the middle stage is the terminal connection part 2b of the L1 phase bar 2, the terminal connection part 2b on the opposite side of the L1 phase bar 2 with the vertical part 2a interposed therebetween is the lower left side. Further, the terminal connection part 3b on the opposite side across the vertical part 3a from the terminal connection part 3b of the L2 phase bar 3 on the left side of the middle stage is the lower right side.

上記導電バーを組み付けた分電盤に用いる回路遮断器４の端子は、１００Ｖ回路であるなら、上部５ａと下部５ｃの凹部に端子６を備える。その状態の回路遮断器４をただ、導電バーの左右に振り分けて接続することで、バランスよく電圧をとることができる。導電バーの中段と下段の相が左右で異なっているので、回路遮断器４の端子位置を変更することなく、施工に時間を掛けずにバランスよく電圧をとることができる。 If the terminal of the circuit breaker 4 used for the distribution board assembled with the conductive bar is a 100V circuit, the terminal 6 is provided in the recesses of the upper part 5a and the lower part 5c. By simply connecting the circuit breaker 4 in this state to the left and right of the conductive bar, the voltage can be taken in a balanced manner. Since the middle and lower phases of the conductive bar are different on the left and right, the voltage can be taken in a balanced manner without changing the terminal position of the circuit breaker 4 and without taking time for the construction.

導電バーは、垂直部も端子接続部も板状体であるので、表面積が大きく放熱しやすいため、導電バーの温度上昇を抑えることができる。 Since the conductive bar is a plate-like body in both the vertical portion and the terminal connection portion, the surface area is large and the heat can be easily radiated, so that the temperature rise of the conductive bar can be suppressed.

プラグイン式の回路遮断器に接続される導電バーの構成を中段と下段で二本一組とし、左右上下に隣接する導電バーの相が異なるように配置したことで、導電バーへの回路遮断器の接続作業が容易で相のバランスよく電圧がとれるようになる。 The configuration of the conductive bars connected to the plug-in circuit breaker is a set of two at the middle and the lower, and the arrangement of the conductive bars adjacent to each other on the left, right, top, bottom is different so that the circuit is cut off to the conductive bars The unit can be connected easily, and the voltage can be taken with a good balance of phases.
