[0005] However, since the conventional body (10) has a hollow structure with a hollow center, in transmission lines with two or more conductors, vibrations caused by wake can easily occur after the wind hits the wire (1), and in transmission lines with four or more conductors, subspan oscillation occurs.

[0006] As such, since the body (10) of the spacer damper is hollow in the center, the wind from the wire (1) and the direct wind pass through the hollow structure hole formed in the center of the body (10), causing noise of a specific frequency range, which resulted in complaints from residents living near the transmission line due to the noise.

[0023] Hereinafter, preferred embodiments of the present invention are described with reference to the accompanying drawings to fully understand the present invention. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. It should be noted that in each drawing, identical components may be illustrated with the same reference numerals. Detailed descriptions of known functions and components that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0024] Referring to FIGS. 3 and 4, the central support type disc-shaped spacer damper device according to an embodiment of the present invention is formed to be installed at regular intervals in the middle of a transmission line between steel towers to prevent damage between lines caused by shaking of the wire (1), and comprises a body (100), a plurality of damping members (110a) (110b) (110c) (110d), and a plurality of clamps (130a) (130b) (130c) (130d).

[0025] That is, the body (100) is a solid disc-shaped body made of a sound-absorbing material having a vibration absorption capacity of at least a certain amount, and a plurality of connecting grooves (102) are formed at regular intervals on the side perimeter so that one end of a plurality of damping members (110a) (110b) (110c) (110d) is inserted into a certain depth inside the body (100), and each of the plurality of connecting grooves (102) is connected so that one end of a damping member (110a) (110b) (110c) (110d) is inserted and is spaced in the direction of the side perimeter of the body (100).

[0026] At this time, the connection gap between the body (100) and the damping members (110a)(110b)(110c)(110d) is filled with a sound-absorbing material having a sound-absorbing capacity greater than a certain amount. The filling of this sound-absorbing material prevents the vortex of wind entering through the connection gap and simultaneously serves to absorb vibration noise caused by the connection gap between the body (100) and the damping members (110a)(110b)(110c)(110d).

[0027] The above body (100) is formed with a symmetrically curved surface (104) such that the side circumference becomes rounded as it extends from the side of the body (100) toward the front and rear, and the curved surface (104) serves to minimize air resistance when struck by wind.

[0028] The above-mentioned multiple damping members (110a) (110b) (110c) (110d) are made of synthetic rubber material having a vibration absorption capacity greater than a certain amount to absorb vibrations of the body (100) or wire (1), and one end of each damping member (110a) (110b) (110c) (110d) is connected to be arranged in four directions around the side perimeter of the body (100), and the other end of each damping member (110a) (110b) (110c) (110d) is connected to a clamp (130a) (130b) (130c) (130d).

[0029] One end of each of the above-mentioned body (100) and a plurality of damping members (110a) (110b) (110c) (110d) is connected by a fastening member (120a) (120b) (120c) (120d) that passes through a connecting groove (102) from the front of the body (100) and penetrates to the rear of the body (100).

[0030] At this time, it is preferable that the plurality of the above-mentioned fastening members (120a)(120b)(120c)(120d) are composed of a combination of bolts and nuts.

[0031] The diameter (A) of the body (100) is made smaller than the length (B) of each of the multiple damping members (110a) (110b) (110c) (110d), thereby minimizing the air contact area applied to the body (100) when the wind blows and serving to reduce noise.

[0032] The above multiple clamps (130a)(130b)(130c)(130d) each serve to clamp the wire (1) of the transmission line.

[0033] As such, since the present invention is a centrally supported disc-shaped spacer damper device with a disc-shaped structure having no hole in the center of the body, horizontal loads caused by wind can be minimized, unpleasant noise previously generated can be reduced to a minimum, and noise complaints from residents living near transmission lines can be resolved and perceptions of power facilities improved through noise reduction in specific frequency ranges.

[0034] In addition, since the body (100) is a central support type disc-shaped spacer damper device in which the damping members (110a) (110b) (110c) (110d) and the body (100) are connected in a central support type while the body (100) is made smaller than the number of damping members (110a) (110b) (110c) (110d), the structure can be simplified compared to a spacer damper having a body with a central hole and a conventional damping member. Furthermore, by reducing the weight of the body (100) by more than 70% and reducing the total weight of the spacer damper by more than half, it is possible to facilitate high-altitude installation / removal work, and there is an advantage of minimizing construction costs and the risk of safety accidents caused by the ease of high-altitude work due to the reduction in total weight.

[0035] Meanwhile, the present invention is not limited to the embodiments described above, but can be implemented with modifications and variations within the scope of the essence of the invention, and such technical concepts to which modifications and variations are applied should also be considered to fall within the scope of the following patent claims.
