Description

  The present invention relates to a jumper wire reinforcement device for a transmission line, and more particularly to a jumper wire reinforcement device that can be easily attached to a connecting plate of a wedge-type retaining clamp (MAT).

  A reinforcing device is attached to the jumper line of the power transmission line for the purpose of securing the tower clearance and reducing the stress generated in the jumper line at the time of lateral swing. Regarding the attachment of the reinforcing device, the metal fittings for attaching the reinforcing wire are previously inserted between the clamp and the tension device, or a part of the metal fitting of the tension device has been diverted.

  FIG. 3 is an installation view of a conventional jumper wire reinforcing device. In FIG. 3, after the reinforcing wire mounting bracket 91 of the conventional jumper wire reinforcing device 90 is attached between the tension device 70 that is attached to the steel tower and tensions the transmission line and the clamp 80 that holds the transmission line. The jumper wire 60 is reinforced by attaching the reinforcement wire 34 of the jumper wire reinforcement device 90 to the reinforcement wire mounting bracket 91 and fixing the jumper wire 60 and the reinforcement wire 34. FIG. 4 is another installation view of the conventional jumper wire reinforcing device. In FIG. 4, after the jumper wire reinforcing device 90 is attached to the bolt hole 72 of the horizontal yoke 71 of the tension device 70, the jumper wire 60 and the reinforcing wire 34 are fixed to reinforce the jumper wire 60. It was.

  However, in the case of FIG. 3, in order to attach the reinforcing wire mounting bracket 91, it is necessary to similarly attach the reinforcing wire mounting bracket 91 to the other tension device 70 side of the steel tower, and keep the jumper wire in a predetermined shape. There was a case where a problem that could not be made occurred. Further, in the case of FIG. 4, there are cases where the bolt holes 72 are not opened at all in the horizontal yoke 71, and there is a problem that the jumper wire reinforcing device 90 cannot be attached.

  Patent Document 1 discloses a jumper wire blow-up prevention device that includes a copper wire that is conductively connected to a jumper wire, is rotatably supported, and has a spiral-shaped wind receiving portion that receives wind to be blown. However, it has a resistance rotating member erected on the outer peripheral surface and a rotating blade that receives the wind to be blown, and the lower wind receiving portion is directed in the forward direction with respect to the wind blowing direction of the resistance rotating member, There is a description that it is provided with a rotation start mechanism that rotates the upper wind receiving portion in the opposite direction.
