Description

例えば変電所における遮断器と断路器は、それぞれの端子接続部間が、両端に羽子板状の端子を備えた接続線により接続される。この発明は、このような接続線の端子と機器の端子接続部との間に介設されるもので、２つの機器が地震等により互いに離れる方向に揺動したときに、接続線に引かれて機器が破損することを防止するためのフレキシブルジョイントに関するものである。   For example, a circuit breaker and a disconnecting switch in a substation are connected to each other between connecting terminals by connecting wires each having a feather-shaped terminal at both ends. The present invention is interposed between the terminal of such a connection line and the terminal connection part of the device. When two devices swing away from each other due to an earthquake or the like, the connection wire is pulled. The present invention relates to a flexible joint for preventing the device from being damaged.

従来のこの種のフレキシブルジョイントとして、特許文献１に記載されたものが知られている。そのフレキシブルジョイントを図５に示す。フレキシブルジョイント２１は、一方の機器の導体Ｂ１と、それと離れた図示しない他の機器の導体との間を接続する接続線Ｗの端子Ｗ１との間に介設される。フレキシブルジョイント２１は、導体Ｂ１に固着される第１の接続体２２と、接続線の端子Ｗ１に固着され、かつ第１の接続体２２に対して相対変位可能に接続される第２の接続体２３と、第１の接続体２２と第２の接続体２３との相対変位に所定の抵抗を付与するばね部材２５と、第１の接続体２２と第２の接続体２３との間を十分な長さの余裕を保持して電気的に接続する可撓性導体２６とを具備する。第１の接続体２２は、導体Ｂ１に固着される基板２２ａを具備する。第２の接続体２３は、端子Ｗ１に固着される基板２３ａを具備する。第１の接続体の基板２２ａと第２の接続体の基板２３ａは、互いに間隔を置いて重なるように配置されると共に、一方向に直線的にガイドされて相対変位可能に組み合わされる。可撓性導体２６は、屈伸可能に折り曲げられて第１の接続体２２と第２の接続体２３との間を電気的に接続する。接続線Ｗが接続する２つの機器間に地震等による所定以上の大きい相対変位が生じると、第１の接続体２２と第２の接続体２３とが、ばね部材２５による抵抗に抗して相対移動することで、機器の破損を防止する。
特開平９−１９９２５２号公報 As this type of conventional flexible joint, one described in Patent Document 1 is known. The flexible joint is shown in FIG. The flexible joint 21 is interposed between a conductor B1 of one device and a terminal W1 of a connection line W that connects between the conductor B1 of another device (not shown) that is separated from the conductor B1. The flexible joint 21 is a first connection body 22 fixed to the conductor B1 and a second connection body fixed to the terminal W1 of the connection line and connected to the first connection body 22 so as to be relatively displaceable. 23, a spring member 25 that gives a predetermined resistance to the relative displacement between the first connection body 22 and the second connection body 23, and a sufficient space between the first connection body 22 and the second connection body 23. And a flexible conductor 26 that is electrically connected while maintaining a sufficient margin. The first connection body 22 includes a substrate 22a fixed to the conductor B1. The second connection body 23 includes a substrate 23a fixed to the terminal W1. The substrate 22a of the first connection body and the substrate 23a of the second connection body are arranged so as to overlap each other with a space therebetween, and are linearly guided in one direction and combined so as to be capable of relative displacement. The flexible conductor 26 is bent so as to be able to bend and stretch, and electrically connects the first connection body 22 and the second connection body 23. When a large relative displacement greater than or equal to a predetermined value occurs due to an earthquake or the like between the two devices to which the connection line W is connected, the first connection body 22 and the second connection body 23 are opposed against the resistance by the spring member 25. By moving, prevent damage to the equipment.
