Description

Line post insulator having a through-hole for passing an electronic cable}

The present invention relates to a line post insulator having wire through holes. More particularly, the present invention relates to a line post insulator having a wire through hole formed in a structure in which a passage through which an electric wire passes through is installed at the center of the insulator to support and insulate the electric wire.

In general, a line post insulator is an insulator that insulates transmission and distribution lines in a state of being installed through a support member such as a wrought iron on the upper side of the telephone pole, and the line post insulator insulates the transmission and distribution lines and the ground on the upper side of the body. The jumper wire is fixed in the horizontal direction through the bind as a means for the purpose.

For example, as shown in FIG. 1, the line post insulator 130 has a fastening line 131 integrally formed on the head, and the jumper wire 131 is horizontally seated in a concave groove forming the upper surface thereof. 140 is fixed by bind 150 so that flow remains in a prevented state.

Therefore, when the jumper wire 140 is fixed to the line post insulator 130 mounted on the support member of the telephone pole, and both ends of the jumper wire 140 are connected to the electric flow line of the power line, the support member Various transmission and distribution lines installed on the upper side of the insulation is to prevent equipment accidents.

However, if the coating of the jumper wire 140 is damaged due to its own hardness or the coating of the jumper wire 140 is damaged by the electromagnetic force of the jumper wire 140 in the process of strongly winding the bind 150, the jumper wire There was a problem of shortening the service life of the transmission and distribution line due to an equipment accident such as disconnection of 140.

In addition, the bind 150 is exposed to the air as it is, for example, when the corrosion caused by the reaction with the rain water or foreign matter to generate a corrosion product on the coating of the jumper wire 140, as well as shorten the life of the jumper wire 140 In addition, the damage to the upper side of the body caused a problem that the various additional costs according to the maintenance of the transmission line.

Accordingly, the present invention is to solve such a problem of the prior art, in order to support and insulate wires such as jumper wires instead of bind fixed line post insulators which are fixed to the head of the line post insulator and bind with wires as in the prior art. It is to provide a line post insulator having a wire through hole that can support the insulator and maintain the insulation by forming a passage through which the wire can pass on the upper side of the body, as well as to minimize the damage to the coating of the wire.

The line post insulator having the wire through hole of the present invention has a structure in which an upper portion of the body can be divided into two parts along a longitudinal dividing line, and through which a wire such as a jumper wire can pass in the transverse direction A hole is formed, and the concave groove formed on one surface in the direction perpendicular to the through hole and the convex protrusions formed on the opposite surface thereof are characterized in that the structure is made of a structure that can be firmly engaged with each other.

The line post insulator having the wire through hole of the present invention has the upper part of the body of the insulator to support and insulate an electric wire such as a jumper wire instead of the bind-fixed line post insulator that fixes and binds the wire to the head of the line post insulator as in the related art. By forming a passage through which the wire can pass, the insulator can support the wire, maintain insulation, and minimize the damage to the wire sheath.

Hereinafter, embodiments will be described so that those skilled in the art can easily implement the present invention, but the present invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

When a part in the specification includes a certain component it means that it can further include the component rather than control other components unless otherwise stated.

FIG. 2 is a side view of a line post insulator having a wire through hole according to the present invention. In FIG. 2, a split line in a longitudinal direction is provided at a central portion of an upper portion of the body of the line post insulator 20. (21) is formed, and this dividing line 21 means that the upper part of the body of the insulator can be divided into two parts, and is designed to pass through the center line of the through-hole 22 described later. In addition, the through hole 22 is formed in the housing 24 located at the center of the upper side of the body, and the wire of the overhead line, such as a jumper wire, penetrates, and the insulator itself supports the wire while insulating it. consist of. In Fig. 2, reference numeral 23 is a skirt, 24 is a housing, 25 is an upper body, and 26 is a base bracket.

Looking at the internal structure of the line post insulator having a wire through hole according to the present invention, Figure 3 in the line post insulator 20 of the present invention by cutting a portion of the upper side along the dividing line 21 of FIG. As shown in the figure, the inner surface of the upper body side of the line post insulator 20, specifically, a wire such as a working line or a jumper line in the transverse direction to the housing 24 portion instead of the skirt 23 portion, the arrow direction. When the concave through hole 22 which can pass through is formed, and the through hole 22 in FIG. 3 is engaged with the concave through hole 22 of the other cutout illustrated in FIG. 4 as shown in FIG. 2. A circular hole will be created, wrapped around the wire passing through it, and will be insulated.

The diameter of the through hole 22 is preferably designed to have a diameter slightly smaller than the size of the wire so that the through hole 22 can support the wire more strongly.

According to FIG. 3, the concave grooves 27 concave orthogonal to the concave through-holes 22 are formed in the longitudinal direction from the central surface of the upper body 25 through the through-holes 22 to the next skirt 23. Then, it extends to the edge end of the skirt 23 in the state bent in the direction perpendicular to the portion where the housing 24 and the skirt 23 meet each other. This recessed part 27 is a part which is firmly fastened when engaging with the convex protrusion part of FIG. 4 mentioned later.

FIG. 4 is a perspective view illustrating the internal structure of the line post insulator 20 of the cut and separated portion of FIG. 3. As described above, FIG. 4 illustrates a structure of the same structure at a position corresponding to the concave recess 27 of the housing 24. The through-hole 22 is formed, and the convex protrusion part 28 is formed in the position corresponding to the recessed recess 27 also.

The line post insulator of FIG. 3 and the cut and separated line post insulator of FIG. 4 may be bound by bind when mutually binding, and may be more firmly and fastened by concave grooves and convex protrusions.

5 illustrates a state in which a line post insulator 20 having a wire through hole according to the present invention is coupled, and a high voltage wire 29 such as a jumper wire is actually penetrated through the through hole, and the wire 29 is bound ( 30), the line post insulator 20 is also wound and fixed together.

The line post insulator having the wire through hole according to the present invention is a conduit and the convex protrusions are in contact with each other to be firmly fastened to create a passage (penetration hole) through which the wire can be made, the center passage of the insulator It is a structure that the high voltage wire penetrates and is primarily supported by the insulator itself, and is insulated. Secondly, the wire is supported by bind, which minimizes damage to the covering of the wire by dispersing the overall force. There is an advantage that can be completely prevented from wire disconnection due to breakage of the upper body of the insulator.

In addition, since only insulators in the defective hanger part need to be replaced when repairing insulators, there is an advantage of reducing work time and construction costs due to partial replacement.
