Attach the jumper reinforcing rod 35 with a bolt 36 that pivotally supports the base end and a bolt 39 inserted through the elongated hole 38 at the base end and one through hole 40 of the adjustment plate 34, and attach the jumper reinforcing rod 35 to the jumper reinforcing rod 35. 41 was used to reinforce the jumper wire. The inclination angle of the jumper reinforcing rod 35 and the shape and slackness of the jumper wire 41 can be adjusted using the bolt 3 inserted into the elongated hole 38.

By the way, the jumper wire becomes long in the conductor tensioning equipment used to stretch ultra-high voltage power transmission lines.
In order to avoid the adverse effects of snow caps that form across the insulators and the tower arms, conductor tension devices installed in areas with heavy snowfall are equipped with tower arm 1 as shown in Figure 1.
Although a long rod 4 is interposed between the insulator and the insulator chain 3, the jumper wire becomes long in this case as well. In cases where the jumper wire becomes long in this way, reinforcement with only one reinforcing rod 35 as shown in Fig. 4 is extremely insufficient, and the jumper wire may be damaged by falling snow from the conductor tension device, large upward wind pressure, etc. Due to the jump, the permissible insulation distance between the conductor tension device and the steel tower could not be maintained, leading to a power outage.

煩雑で時間のかかる作業を必要とした。 In addition, the bolt 3 at the base end of the reinforcing rod 35
Since the length between 6 and 39 is very short compared to the length between the wire clip near the adjustment plate for attaching the jumper wire 41 to the jumper reinforcing rod 35 and the pivot bolt 36, the passage of the adjustment plate 34 is Even if the pitch of the holes 40 is made smaller, there is a problem in that the slackness of the jumper wire changes greatly. Furthermore, according to the method described in Japanese Utility Model Publication No. 40-7004 as a means for adjusting the slackness of the jumper wire, multiple replacement holes on the fan-shaped support plate are selected and installed using a fixture fixed to the stretched wire. Each time the slackness of the jumper wire was changed, the stretched electric wire was removed from the fan-shaped support plate and reattached, which was a complicated and time-consuming task.

を提供することを目的とする。 The present invention has been developed in view of the above points, and has a relatively simple structure that greatly enhances the effect of preventing jumper wire from jumping up, and also allows the shape and slack of the jumper wire to be easily changed without impairing this effect. Moreover, it is an object of the present invention to provide a jumper reinforcing device that can be finely adjusted.

A connecting fitting 6 in which one insulator chain 3 and one conductor clamp 5 are connected in series in a conductor tension device has a plurality of jumper reinforcing materials 11 formed on the lower conductor side and the upper end of the jumper reinforcing material 11 on the lower insulator side. The upper end of the connecting member 14 is attached to one of the attachment holes 16 by a connector so as to be movable up and down, and the lower end of the connecting member 14 is connected to the lower end side of the jumper reinforcing member 11 by a connector. As a result, the jumper reinforcing material 11 forms a downward triangular frame with the connecting fittings 6 and the connecting members 14, so that the rigidity of the jumper reinforcing material 11 in the vertical direction is particularly increased. For this reason, the deterrent force against deflection of the jumper wire 17, especially against jumping of the jumper wire 17, is large. Furthermore, since the connecting fittings 6 for attaching the jumper reinforcing material 11 and the connecting material 14 are stretched in a straight line together with the insulator chain 3, the conductor clamp 5, and the conductor, the jumper wire can be efficiently
Prevents the jump of 7.

ることになる。 Therefore, since the connecting member 14 is adapted to change its attachment position to the connecting fitting 6 by using the plurality of attachment holes 16 of the connecting fitting 6, the slackness and shape of the jumper wire 17 depend on the amount of attachment position displacement. It will change accordingly.

い。 It should be noted that the present invention is not limited to the above embodiments, and can be modified in various ways without departing from the gist of the present invention. For example, although the conductor tension device of the embodiment has the long rod 4, it goes without saying that it can also be applied to a normal conductor tension device without a long rod.

調整することができる。 The connecting member, which connects the upper end to the conductor side of the connecting fitting and the lower end to the lower end side (free end side) of the jumper reinforcing material, is not only used to reinforce the jumper reinforcing material, but also to be formed on the lower insulator side of the connecting fitting. By changing the mounting position to the connecting fitting using multiple mounting holes, the shape and slackness of the jumper wire changes in accordance with the amount of displacement of the mounting position, so the shape and slackness of the jumper wire can be easily adjusted. Moreover, it can be finely adjusted.
