Description

A multipurpose variable device for supporting the bended power cable

The present invention, for example, multi-purpose for supporting flexure cable that can support the height and horizontal angle to suit the cable curvature radius to support the bent cable in underground distribution structures such as cable processing chambers, power outlets, manholes in the substation It relates to a variable bracket.

In general, when supporting a large amount of cable in the underground distribution structure, the brackets such as support cable hangers are installed and utilized. When supporting the cables in the cable processing room of the substation using the same brackets as the conventional cable hangers, In other words, when some lines are drawn from the substation blocker to the cable processing room in the basement, the cable movement paths are diversified spatially, so that the vertical and horizontal cable movement paths cannot be made, and the bolts fixing the CD cleats are twisted. In addition, the cable hanger is not able to contact this CD cleat, which leads to a gap, and when it is difficult to maintain the cable allowable radius of curvature, acceleration of mechanical deterioration occurs and a large electric power accident is caused by load concentration on the secondary terminal cable connection point of the substation cutout. There was a problem providing the cause.

In addition, due to long-term changes, there is a high possibility of progressing to damage of the CD cleat due to the cable side pressure.

On the other hand, when using the conventional cable support bracket in the power sphere, the washer of the temporary support bracket of the moving cable between the two side walls in the power sphere is not tolerated by the change in retirement age, and also prevented from falling off the ceiling for a long time, The mechanical deterioration of the cable acts as a cause of insulation deterioration, resulting in a decrease in distribution power quality.

In addition, various problems have been raised in the cable processing chamber of the substation described above.

Finally, when the conventional cable support bracket is used in the manhole, the cable hanger supporting the curvature cable in the manhole is adjusted in a batch, but cannot be varied for each rotation, so that the cable side pressure cannot be dispersed, and eventually the cable hanger Failure to maintain the cable curvature radius due to breakage of the installed cable cleats and loosening of the cleat bolts has resulted in narrowing of the work intermediate and mechanical deterioration of the cable.

Therefore, the present invention was devised to solve the above-described problems, and a plurality of cable lines can be adjusted in different directions in a cable hanger while horizontal and vertical height adjustments are made, and at the same time, a substation cable processing room and a power ceiling Its purpose is to provide a versatile, variable bracket for supporting standard flexure cables that can be installed in all locations of underground distribution structures in sidewalls and manholes.

The present invention for achieving the above object is a cable hanger for holding the cable in various underground power distribution structure, the cable support hanger is a CD top, CD bottom, horizontal rotating upper bracket and CD in contact with the CD fixed upper cover The rotating variable bracket is fixed by bolts in turn, and the CD rotating variable bracket supporting plate is provided with a feldspar in between, and the height adjustment upper bracket and the lower side are adjusted to both sides of the cable hanger in contact with the CD rotating variable bracket supporting plate. Brackets are installed but fastened to their respective bolts.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall separated perspective view of the multi-purpose variable bracket 15 for supporting the bending cable 102 in the underground distribution structure according to the present invention.

The present invention, in the support bracket of the cable hanger for holding the cable 102 in various underground distribution structures, the CD upper portion (2) in contact with the CD fixed upper cover (1), CD lower portion (3), horizontal rotation top The bracket 4 and the CD rotation variable bracket 5 are in turn fixed by the bolts 6, and the CD rotation variable bracket support plate 8 has a CD rotation variable bracket support plate 8 therebetween with a feldspar 7 therebetween. And a height adjusting upper bracket 10 and a lower bracket 11 are installed on both sides of the cable hanger 9 in contact with the CD rotating variable bracket support plate 8, which are respectively bolts 12, 13, 14. Is fastened.

Therefore, in the underground distribution structure 101, the horizontal rotating upper bracket 4, the CD rotating variable bracket 5, and the CD rotating variable bracket support plate 8, in which the CD cleats are variable left and right in a straight cable hanger, are installed 180 in the horizontal direction. It is rotatable at an angle.

Here, the horizontal rotating upper bracket 4 is fixed to the support bolt 6 of the CD cleat, and at the same time, the elliptical groove 4a is arranged to adjust in the horizontal direction.

In addition, a feldspar 7, which is a height-adjusting wing, is placed on the bottom of the CD-rotating variable bracket 5 to compensate for gaps in the coupling parts.

On the other hand, by installing a hinge between the CD rotating variable bracket backing plate (8) and the CD rotating variable bracket (5) to compensate for the gap between the coupling parts, and at the same time to secure the present invention to the cable hanger (9) The elliptical groove and the concave rectangular groove are formed to be able to be changed in any direction so that the radius of curvature of the cable is maintained.
