本発胡は、架空送電線接続部の放熱装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a heat dissipation device for connecting parts of overhead power transmission lines.
最近、電力需要が旺盛で、特に夏期のピーク時に、送電
線に大電流が長時間継続して流れると、送電線の接続部
で発熱の問題が生じる。Recently, there has been a strong demand for electricity, especially during peak periods in the summer, and when large currents continue to flow through power transmission lines for long periods of time, heat generation occurs at the connections of the power lines.
また現在では通常の耐熱電線以外に、常時使用温度が２
００℃を越える超耐熱電線が使用されており、接続部の
過熱防止対策は一層重要な課題となりつつある。In addition to regular heat-resistant wires, there are also
Ultra-heat resistant electric wires exceeding 00°C are being used, and measures to prevent overheating of connections are becoming an increasingly important issue.

昭５９−１０７０１号公報）。Therefore, attempts have been made to suppress the temperature rise at the connection by attaching a radiator to the wire at the mouth of the compression fitting that connects the overhead power transmission line, or to the outer periphery of the fitting itself (Utility Model Publication No. 59-10701). Public bulletin).

が互いに衝突するおそれもあり、またコロナ特性上も問
題がある。However, the above structure may not be able to sufficiently dissipate heat generated at the connection portion. In other words, when a large current flows, such as in the super heat-resistant wires mentioned above, the amount of heat generated at the connections becomes extremely large, so in order to suppress this to a sufficiently low temperature, the heat sink must be extremely large or the , the number of pieces increases, making it impractical. If the radiator becomes larger, there is a risk that the radiators attached to each elementary conductor will collide with each other in a multi-conductor power transmission line, and there is also a problem in terms of corona characteristics.

具２２により締め付けられる構造となっている。The heat dissipation device 11 of this overhead power transmission line connection section is for a retaining clamp, and grip fittings 13.1 each have heat dissipation fins 15 at both ends of a flexible conductor 12 made of twisted aluminum wire or the like.
4 are compressed and connected. Grip fitting 13.14
In this example, one of the gripping metal fittings 13 grips the main body 17 of the restraining clamp that compresses the main line 16 of the overhead power transmission line, and the other gripping metal fitting 14 grips the main body 17 of the overhead power transmission line. The jumper socket 19 in which the jumper wire 18 is compressed is held. For this reason, both gripping fittings 13 and 14 have a structure in which two halves are hingedly connected on one side by a pin 21, and bolts and nuts are tightened by a tool 22 on the other side.

。As shown in FIIJ-2, one of the gripping metal fittings 13 has a regular hexagonal inner surface in order to directly grip the retaining clamp body 17 compressed into a regular hexagonal cross section, while the other gripping metal fitting 14 has a regular hexagonal inner surface as shown in Figure 3. As shown in FIG. 2, the jumper socket 19 is gripped through a two-split collar 23 whose inner surface is a regular hexagon and whose outer surface is circular. This is because the direction of the compressed new surface of the retaining clamp body 17 and the compressed cross section of the jumper socket 19 do not necessarily have a constant relationship.

This heat dissipation device 11 for the overhead power transmission line is also for a straight sleeve 26 for compressively connecting the main parts 1i16 of the overhead power transmission line, and is for the flexible conductor 1.
A gripping metal fitting 24 having a heat radiation fin 15 is connected to one end of the wire by compression, and a wire gripping metal fitting 27 without radiation fins is connected to the other end by compression. Each of the gripping metal fittings 24 and 27 is divided into two parts, and one gripping metal fitting 24 grips one end side of the linear sleeve 26, and the other gripping metal fitting 27 grips the main line 16 of the overhead power transmission line near the other end of the linear sleeve 26.

効果がある。またこのため放熱装置を小型化できる利点
がある。As explained above, if the heat dissipation device according to the present invention is used, the heat dissipation effect of the heat dissipation fins and the reduction in the amount of heat generated by the compression fitting due to the current being divided between the compression fitting and the heat dissipation device will reduce the heat dissipation of the compression fitting. It has the effect of efficiently suppressing temperature rise. Moreover, this has the advantage that the heat dissipation device can be made smaller.
