Description

本発明は、バスダクト の導体中間部において、プラグイン機器を介して電力を分岐するバスダクトのプラグインホールに関する。   The present invention relates to a plug-in hole of a bus duct that branches power through a plug-in device at a conductor intermediate part of the bus duct.

バスダクト は、工場施設やビルの主電力供給ラインなどに広く用いられており、一般に、複数の板状の裸導体を並列させ、各導体間を絶縁材で離間してハウジング内に収納保持するものと、絶縁被覆された板状の電気導体を複数並列させてハウジング内に収納保持されたものが知られている。これらバスダクトのハウジングの一面には、プラグインホールが設けられ、このプラグインホールにプラグイン機器が取り付けられ、バスダクトから電力を分岐することが行われている。   Bus ducts are widely used in factory facilities and main power supply lines of buildings. Generally, a plurality of plate-like bare conductors are arranged in parallel, and the conductors are stored and held in a housing separated by an insulating material. In addition, a plurality of insulating plate-like electric conductors are stored in parallel in a housing. A plug-in hole is provided on one surface of the housing of the bus duct, and a plug-in device is attached to the plug-in hole so that power is branched from the bus duct.

プラグインホールの配列形状は種々のものが知られているが、その内の一つに、図２に示すように、バスダクト１のハウジング２の上面に、中相プラグインホールＡを頂点にして他の２つの外相プラグインホールＢＣが二等辺三角形形状となるように配置された３線式プラグインホールＤが公知である。例えば（特許文献１〜３参照）   Various arrangements of plug-in holes are known, and one of them is shown in FIG. 2, with the middle-phase plug-in hole A at the top of the housing 2 of the bus duct 1. A three-wire plug-in hole D in which the other two external phase plug-in holes BC are arranged in an isosceles triangle shape is known. For example (see Patent Documents 1 to 3)

このような３線式プラグインホールＤには、図２に示すように、プラグインホールＤの三角形形状と略同一に配置された挿入ブスバ１１、１２、１３を底面に持つプラグイン機器１０の前記挿入ブスバ１１、１２、１３をそれぞれ前記プラグインホールＡ、Ｂ、Ｃに差し込むことによって、バスダクト１の各導体ｐｑｒに電気接続された図示しない接触片を介して、各導体ｐｑｒから電力をプラグイン機器１０側に取り出すことができるようになっている。   As shown in FIG. 2, the three-wire plug-in hole D has a plug-in device 10 having insertion bus bars 11, 12, and 13 arranged substantially in the same shape as the triangular shape of the plug-in hole D. By inserting the insertion bus bars 11, 12, and 13 into the plug-in holes A, B, and C, respectively, power is plugged from the conductors pqr through contact pieces (not shown) that are electrically connected to the conductors pqr of the bus duct 1. It can be taken out to the in-device 10 side.

プラグイン機器１０は、プラグインスイッチボックスなどが知られており、プラグイン機器１０の内部には、挿入ブスバ１１、１２、１３と電気的に接続される連結部や、この連結部と電気的に接続されると共に、分岐のための別の二次側ケーブルが接続される図示しない接続端子などを具える。また、連結部と接続端子との間にプラグインブレーカ等を具えるものも存在する。   The plug-in device 10 is known as a plug-in switch box or the like. Inside the plug-in device 10, a connecting portion that is electrically connected to the insertion bus bars 11, 12, and 13, or And a connection terminal (not shown) to which another secondary cable for branching is connected. In addition, some include a plug-in breaker or the like between the connecting portion and the connection terminal.

しかしながら、上記の３線式プラグインホールＤは中相プラグインホールＡを頂点として他の外相プラグインホールＢ、Ｃが二等辺三角形となるように配置されているため、それぞれの挿入ブスバ１１〜１３はそれぞれ特定のプラグインホールＡ〜Ｃにしか差し込むことができず、この結果、プラグイン機器１０を一定の方向にしか配置させることができず、分岐ケーブルである二次側ケーブルの取り出し方向が特定されていた。   However, the above-described three-wire plug-in hole D is arranged so that the other external phase plug-in holes B and C are isosceles triangles with the middle phase plug-in hole A as a vertex. 13 can only be inserted into specific plug-in holes A to C, respectively. As a result, the plug-in device 10 can be arranged only in a certain direction, and the take-out direction of the secondary side cable which is a branch cable Has been identified.

このため、二次側ケーブルの取り出し方向を上記の反対側から取り出すためには、プラグイン機器１０の挿入ブスバ１１〜１３の配置位置を１８０度回転させたものにするか、プラグインホールＡ〜Ｃの配置位置を１８０度回転させたものにするか、または設計時に二次側ケーブルの引き出し方向を反対側にしたものを構成するなどが必要であった。   For this reason, in order to take out the direction of taking out the secondary cable from the opposite side, the arrangement position of the insertion bus bars 11 to 13 of the plug-in device 10 is rotated 180 degrees, or the plug-in holes A to It was necessary to make the arrangement position of C rotated 180 degrees, or to configure the secondary cable with the drawing direction of the secondary cable opposite at the time of design.

本発明は、かかる点に鑑みなされたもので、バスダクトの一面に、中相プラグインホールを頂点にして他の外相プラグインホールが三角形状に形成された3線式プラグインホールにおいて、前記他の外相プラグインホールを基準とする前記中相プラグインホールの対称位置に第二の中相プラグインホールが配置されていることを特徴とする３線式プラグインホールである。   The present invention has been made in view of the above points. In the three-wire plug-in hole in which another external phase plug-in hole is formed in a triangular shape on the one surface of the bus duct with the middle-phase plug-in hole as a vertex, the other A three-wire plug-in hole is characterized in that a second medium-phase plug-in hole is disposed at a symmetrical position of the medium-phase plug-in hole with respect to the outer-phase plug-in hole.

本発明は、他の外相プラグインホールを基準にして前記中相プラグインホールの対称位置に第二の中相プラグインホールが配置されているため、プラグイン機器に形成された中相挿入ブスバを第二の中層プラグインホールに差し替えることにより、容易にプラグイン機器の配置向きを変えることができ、いずれの方向からも二次側ケーブルを取り出すことができる効果を有する。   In the present invention, since the second intermediate phase plug-in hole is arranged at a symmetrical position of the intermediate phase plug-in hole with respect to another external phase plug-in hole, the intermediate phase insertion bus bar formed in the plug-in device is provided. Is replaced with the second middle layer plug-in hole, so that the orientation of the plug-in device can be easily changed, and the secondary cable can be taken out from either direction.

以下本発明を図示した実施例により説明する。図において、Ｅは本実施例における３線式プラグインホールを示すものである。本３線式プラグインホールＥは図２に示すプラグインホールＤに比較して、外相プラグインホールＢ、Ｃを基準とする中相プラグインホールＡの線対称位置に第二の中相プラグインホールＡ'が配置されている点が異なり、その他の構成は同一である。   The present invention will be described below with reference to illustrated embodiments. In the figure, E indicates a three-wire plug-in hole in this embodiment. Compared with the plug-in hole D shown in FIG. 2, the three-wire plug-in hole E is a second medium-phase plug at a position symmetrical with respect to the medium-phase plug-in hole A with respect to the external phase plug-in holes B and C. The other points are the same except that the in-hole A ′ is arranged.

第二の中相プラグインホールＡ'の位置におけるハウジング２内には、中相プラグインホールと同様の導体に接続された図示しない接触片が配置されている。なお、図１において、１０'はプラグイン機器１０を１８０度回転させたものを示している。   In the housing 2 at the position of the second middle phase plug-in hole A ′, a contact piece (not shown) connected to the same conductor as the middle phase plug-in hole is arranged. In FIG. 1, reference numeral 10 ′ denotes the plug-in device 10 rotated 180 degrees.

これによって、本発明の実施例は、プラグイン機器１０の挿入ブスバ１１〜１３を従来と同様にプラグインホールＡ〜Ｃに挿入することができ、またプラグイン機器１０を１８０度回転させたプラグイン機器１０'の挿入ブスバ１１〜１２をプラグインホールＡ'、Ｂ、Ｃに挿入させることができる。
この結果、容易にプラグイン機器の向きを変えることができる。 Thus, according to the embodiment of the present invention, the insertion bus bars 11 to 13 of the plug-in device 10 can be inserted into the plug-in holes A to C as in the prior art, and the plug device 10 is rotated 180 degrees. The insertion bus bars 11 to 12 of the in-device 10 ′ can be inserted into the plug-in holes A ′, B, and C.
As a result, the orientation of the plug-in device can be easily changed.
