In the device described in Japanese Utility Model Publication No. 40-25398, the amount of extension of the tensioner by shearing with the shear pin corresponds to the length of the slit 29 of the movable link member 28 on the axis of the tensioner. Therefore, since the length of the tensioning device increases as the amount of stretching increases, it is difficult to apply this method to applications that require a certain amount of stretching, such as preventing collapse of a support structure for a tensioning device. Also, Utsukai Showa 58-3780
In the device described in the publication, the amount of elongation of the tensile device due to shear pin shearing is calculated from the sum of the lengths of the hypotenuses of the triangle obtained by connecting the connecting shafts 39, 36, and 40 of the pair of connecting members 33 and 34 to the length of the base. Corresponds to the length obtained by subtracting . For this reason, the amount of extension is even shorter than that of the above-mentioned other conventional device, and the tension reduction effect is further reduced. Furthermore, the conventional device as described above is disposed on the wire side and cannot work on live wires, and there is a risk of corona generation due to the protrusion.

In order to solve the above-mentioned problems, in the present invention, the support structure side yoke of the tension insulator device is divided into a support structure side yoke part and an insulator side yoke part, and both yoke parts have a connecting piece that is bent and extended by a pivot. Connect the two freely connected connecting members with a support shaft, and connect the opposing support shafts of both yoke parts with a broken member while both connecting members are folded so that the pivot is located at the center of the yoke.

In the present invention, the two connecting members that connect the two yoke parts normally carry the load of the electric wires etc. in the folded state, but they are designed to be resistant to ice and snow adhering to the electric wires. When abnormal tension is applied to the wire due to wind pressure or extremely strong wind pressure such as a typhoon, the broken material breaks, and as a result, the wire flows from the insulator side yoke toward the wire side, and both connecting materials open to both sides. Therefore, the shock absorbing material also breaks, and the connecting material opens until the pivot and both support shafts are in a straight line, obtaining a large amount of stretch and relaxing the tension in the wire. At this time, the shock caused by the breakage of the breakable material is alleviated by the shock absorbing material that breaks subsequent to the breakage of the breakable material.

Embodiments of the present invention will be described with reference to the drawings. 1st
In the figure, reference numeral 1 denotes an abnormal tension reducing device installed at the yoke on the tower side of the tension insulator device, which is constructed by connecting the yoke part 2 on the tower side and the yoke part 3 on the insulator side by a connecting mechanism 4. Part 2 is attached to a steel tower arm (not shown) via right angle clevis 5, right angle clevis link 6, etc., and insulator side yoke part 3 is attached to right angle clevis link 7, insulator 8, right angle clevis 9, double yoke 10, right angle clevis. 11 to a tension clamp 12.

A connecting member 15 formed by connecting a set of connecting pieces 13 and one connecting piece 13 having a bifurcated portion at one end in a flexible and extensible manner with a pivot 14 is attached to both ends of the yoke portions 2 and 3 so as to be rotatable with a support shaft 16, respectively. At the same time, with the connecting member 15 folded so that the pivot shaft 14 is located at the center of the yoke, both ends of the opposing pivot shaft 14 are connected by shock absorbing members 18 each having a notch 17, and further, at the yoke end. Both ends of opposing support shafts 16 are connected by breakable members 20 each having a notch 19. Therefore, the four breakable materials 20 are designed so that they break when abnormal tension occurs, and the shock absorbing material 18
The spacing between the notches is determined so that the connecting members 15 are broken by the opening force of the connecting members 15 after the breaking member 20 is broken.

置、鉄塔に与える悪影響を防止している。 Since this embodiment has the above-mentioned configuration, the connecting member 15 normally carries the load of the electric wires etc. in the folded state, but it is difficult to prevent ice and snow from adhering to the electric wires, and is resistant to icing and snow. If abnormal tension is applied to the wire due to wind pressure or extremely strong wind pressure such as a typhoon, four pieces of broken material 20
is broken at 19 notches, and as a result, the insulator side yoke portion 3 flows toward the wire side, and both connecting members 1
5 opens to both sides, and the shock absorbing material 18 also breaks.
As a result, the insulator side yoke portion 3 is pulled out until the pivot shaft 14 and the two support shafts 16 are aligned in a straight line as shown in FIG. 6, and the tension of the electric wire is relaxed. That is, in this embodiment, the breakable material 20 is first broken and then the shock absorbing material 18 is broken due to the generation of abnormal tension, so that the shock caused by the breakage of the breakable material 20 is alleviated, while both the connecting members 15 are By stretching from the folded state in the wire tensioning direction, a large amount of stretch can be obtained, which can effectively relax the tension of the wire and prevent abnormal tension from having a negative effect on the tension insulator device and the steel tower. ing.

Alternatively, a plurality of connecting members 15 may be connected in series while keeping the width of the yoke portion unchanged.

As is clear from the above explanation, according to the present invention, the connecting member interposed in the support structure side yoke in a folded state is greatly expanded due to the generation of abnormal tension, so that the wire tension is reduced. The condition can be effectively relaxed, and damage to the tension-resistant insulator device and supporting structure due to abnormal tension can be reliably prevented. In particular, in the present invention, a considerable amount of elongation can be obtained without making the normal tension insulator device length too long.
This helps prevent the support structure from collapsing due to excessive tension imbalance between the left and right spans that sandwich the support structure. In addition, since the device of the present invention is installed at the yoke on the support structure side, there is no need to worry about corona generation, and live wire work can be performed if necessary.Furthermore, existing tension insulator devices can be modified relatively easily. It is economical because it can be applied in
