Description

[Detailed Description of the Invention] (Industrial field of application) When a jumper wire or jumper wire reinforcing metal fittings are shaken by wind from the side, or when a large amount of air is blown to the windward side of the jumper wire or jumper wire reinforcing metal fittings. If there is snow, the tension device may be twisted and the jumper wire may approach the tower. The present invention relates to a jumper wire-reinforced tensioning device with a weight for preventing twisting of a tensioning device in which ball-socket insulators are continuously connected in such a case.

(Prior Art) FIGS. 6 and 7 show a conventional tensioning device of this type. Fig. 6 shows a tensioning device using an insulator chain in which clevis insulators are connected.

Horn, 7 is a series of insulators connecting clevis insulators, 8 is a horn mounting bracket, 9 and 10 are arc horns, 11 is a parallel clevis, 12 is a jumper wire reinforcing bracket, 13 is a jumper wire reinforcing bracket, and 14 is a parallel clevis. , 15 is a fan-shaped link, 16 is a parallel clevis, 17 is a compression type clamp,
18 is a jumper line.

In the conventional tension device shown in FIG. 6 and FIG. 7 described above, the jumper wire and the jumper wire reinforcing metal fittings are shaken by the wind from the side or the wind of the jumper wire and the jumper wire reinforcing metal fittings. As a result of a large amount of snow accumulating on the upper side, even if a twisting force is applied to the tensioning device, the conventional device shown in Figs. 6 and 7 is free because all the connecting parts are of the clevis and link type. It was supposed to not turn to.

(Problems to be solved by the invention) Recently, it has been demanded to increase the diameter of a conductor. However, since increasing the diameter of the conductor increases the tensile strength of the insulator insulator, the tensile strength device for the conductor has a tensile strength. There is a demand for an insulator having high strength and excellent stain resistance (salt resistance). However, an insulator having a high tensile strength and a function excellent in antifouling performance is a ball socket type insulator.

However, since the ball-socket insulator has a structure in which the socket portion of the cap fitting and the ball portion on the pin side are connected to each other, when the ball-socket insulator is incorporated in the tension device, the socket portion and the pin portion are Since the insulator rotates with the side ball part, the jumper wire and jumper wire reinforcing metal fittings become unstable, and when they are shaken by the wind from the side, or to the windward side of the jumper wire and jumper wire reinforcing metal fittings. When a large amount of snow is generated, the tension device is twisted, and as a result, the jumper wire approaches the tower.

Moreover, even if an attempt is made to swing the jumper wire or jumper wire reinforcement fittings to the side away from the tower, the weight of the jumper wire or jumper wire reinforcement fittings further promotes the twisting of the tensioning device, and the jumper wires, etc. There was also a problem that it could not be avoided from the tower.

(Means for Solving Problems) In order to solve the above-mentioned problems, in the present invention, via a jumper wire reinforcement attachment fitting on the line side of a tensioning device in which ball-socket insulators are continuously connected, Jumper wire reinforcement fittings equipped with a catenary angle adjustment plate, a swing angle adjustment plate, and a horizontal angle adjustment plate that can swing the jumper wire sideways in a predetermined direction toward this tension device. At the same time as mounting, a weight composed of a split piece is provided on the symmetrical side of the jumper wire reinforcing metal fittings through the jumper wire reinforcing tool mounting metal fitting, and another weight is provided directly below the connecting central axis of the tension resistant device through a rod. A weight is provided to suppress the rotation of the tensioning device with respect to the central axis of connection, thereby forming a jumper wire reinforced tensioning device with a weight.

(Operation) As described above, the tension device of the present invention uses the insulator string in which the ball-socket insulators are continuously connected, so that the tensile strength is increased and the stain resistance performance such as salt resistance is also improved.

Also, since the weights of the jumper wires and jumper wire reinforcing metal fittings swung up to the side away from the steel tower are counteracted and the weights are provided on the symmetrical side of them, it is possible to suppress the rotation of the tension resistant device and stabilize the device. .
