Embodiment Construction
[0034] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, the embodiment shown below is only an example, and various embodiment can be acquired within the scope of the present invention.
[0035]
[0036] figure 1 is the front view of the spacer. figure 2 It is a plan view of the spacer bars holding the power lines. image 3 is a front view showing the linker structure. The spacer bars 1 hold a plurality of power lines 10 independently so as not to come into contact with each other.
[0037] The spacer 1 includes a clip 2 , a support body 3 and a connecting body 4 .
[0038] (clamp)
[0039] Such as figure 1 , figure 2 As shown, the clamps 2 are tools for clamping the power transmission line 10 , for example, four are provided relative to the support body 3 . Thereby, one spacer bar 1 can sandwich four power transmission lines 10 . In addition, the number of clamps 2 is not limited to four,...

Abstract
The invention provides a spacer and a design method for the spacer. The spacer can relieve external force acting on a clamped part while power transmission lines generate sub-span vibration. The spacer (1) includes: a plurality of line clamps (2) for each independently clamping a plurality of power transmission lines (10); a support body (3) for supporting all the line clamps in the state that all the power transmission lines clamped by all the line clamps keep interval; and connection members (4) for connecting the line clamps and the support body and allowing the line clamps to rotate relative to the support body. Each connection body is provided with a frame (41) arranged on the support body, a shaft body (42) which is freely and rotabably embedded in the frame and has a plurality of projections (42b), and an elastic body (43) arranged between the frame and the shaft body, wherein sections orthogonal to the axial direction of the shaft body of the projections are roughly similar in shape in the axial direction and have pins for connecting the line clamps to specified positions.
Description
technical field [0001] The invention relates to a spacer bar and a design method of the spacer bar, which keeps a distance between a plurality of power transmission lines and clamps them to prevent them from contacting each other. Background technique [0002] In multi-conductor transmission lines, in order to prevent damage caused by collision between transmission lines, spacers are generally used as spacers. However, the transmission lines between the spacers sometimes generate low-frequency, relatively large-amplitude self-excited vibrations, that is, sub-gap vibrations due to wind, which can cause damage to the transmission lines and spacers. [0003] The spacer bar includes a plurality of clamps that independently hold each power transmission line, a support body that supports each clamp while maintaining a predetermined interval, and a connecting body that connects the clamps and the support body. [0004] The connecting body is composed of a box-shaped connecting por...
