Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cable support device for a power distribution cable,

The present invention relates to an electric wire supporting apparatus for an electric wire of a power distribution system, and more particularly, to an electric wire supporting apparatus for an electric wire of a power distribution system, which can fix an insulator supporting the electric wire to a pole without a separate fastening member, And more particularly, to a wire support apparatus for an electric pole of a power distribution system, which can reduce the time and cost required for installation and replacement of a device.

Generally, when a power path is examined, a high-voltage power is transmitted from a power plant to each substation through a power transmission line of a power transmission tower, and a multi-stage transforming process is performed. Then, along a power distribution path such as a concrete pole, .

Therefore, a support (referred to as Kwangwang Gold) is installed on the top of the pole, and the high-voltage cables are connected and fixed.

The shinkansen which is installed at the upper part of the electric pole is used to connect a plurality of suspending insulators and supporting insulators to the electric pole so as to be able to install the electric cable. The light pole is arranged on both sides of the pole, and a separate "U" (Hereinafter referred to as "U " -type bolt), which is wrapped around the pole and is fastened to the pole by means of a fastening nut.

However, since the conventional light-weight mounting structure as described above is simply supported by the "U" -shaped fasteners, when the fatigue load by the cable is continuously applied to the fasteners, The gold is sagged to the bottom, which causes the bearing capacity of the high-voltage cable to remarkably decrease, which eventually leads to a problem of triggering a safety accident. In addition, since a large number of fasteners are required in the installation of a large number of light guide bars, there is a problem in that construction is difficult. In the conventional light guide plate installation structure, a jumper wire connecting the high- Therefore, it is pointed out that the connection part with the high-voltage cable is lost.

Patent Document No. 10-818556 (Patent Document 1) has been proposed as a method for solving such conventional problems. However, the upper and lower ends of the pair of right and left shafts are supported by a high-tension cable that always requires tension from the line post insulator Since the supporting plate shape is formed in a direction orthogonal to the direction of the tensile force of the high-voltage cable, the structure for supporting a strong external force that is not expected due to the elastic supporting force of the supporting plate When the unexpected large external force is applied to the high-voltage cable or the electric wire, it can not guarantee the stable support by the mechanical strength alone.

These unexpected external forces occur in a variety of ways, for example, when a high-altitude ladder for lifting ladders loses its center when the ladder is lifted, a safety accident that covers the high-voltage cable by surrounding buildings or electric poles, It is not easy to prevent accidents because the force direction of the external force acts radially when there is an uneven settlement in the ground where the electric pole is installed.

In order to solve these problems, the present invention has proposed Registration Practical Utility Model No. 20-0445770 (Patent Document 2) and Registration Practical Utility Model No. 20-0445769 (Patent Document 3) filed by the applicant.

Patent Literature 2 and Patent Literature 3 disclose a pail upper support including a pair of upper and lower front and rear support rods formed on the upper and lower portions of the pore to form a pore in preparation for an external force, A support bar having a male screw portion on both side edges of the support bar and a supporting bar which is provided at equal intervals between the outer side surfaces of the upper and lower end front and rear prevention zones, A spring stay having a release spring at the edge of the spring stay and having a female screw threadedly engaged with a male screw portion of the support bar in a direction facing the spring stay, And the cap nut. The upper and lower end front and rear supports In order to provide an elastic force against the tensile force applied to the upper and lower ends of the upper and lower ends, a structure including a flexible elastic rubber material and an elastic spring constituting a composite structure is provided on the front and rear support rods, The intersection of the front and back supports and the pores is weak. Of course, the impact of the external force can be partially absorbed by the elastic means provided at the upper and lower ends of the front and rear support rods. However, since the upper and lower front and rear zones opposed to each other at the spacing meet at the intersection with the rhombus, Often occurs.

In addition, since the external force acts in an irregular direction in which the force does not act in a certain direction but is radial, there is a limitation in absorbing the impact only by the tension means provided on the upper and lower stage front and rear support members.

In order to solve the above-mentioned problems, a wire support apparatus has been developed. The wire support apparatus according to the related art includes a support member inserted in the left and right square rods of the cap unit, The supporting member 20 includes a plurality of fastening pieces for bolt-fastening the high-voltage cable from the front to the rear in a multi-step manner so as to face each other while being continuously formed in the upper and lower vertical directions with reference to the hollow inserted into the left and right rectangular rods, Each of the recessed rounding portions formed on the inner surface of the piece to control a stepped portion movement force of the rod inserted into the slot which reacts to a radial acting force when an external force is generated, The rod is inserted in the transverse direction and inserted into the rod, allowing movement of the rod in response to the radial force acting on the external force. Each of the elongated holes being formed in a rectangular shape at the center of the supporting member and inserted into the left and right rectangular bars of the cap portion to control the idle rotation of the supporting member when an external force is generated And a fastening hole for fastening the support member, which is connected to the high-voltage cable in a front-rear direction, with a bolt inserted into the rectangular bar.
