Description

Space maintenance device of distribution line {SPACE MAINTAINING APPARATUS OF DISTRIBUTION LINES}

The present invention relates to a space maintenance device of the distribution line, more specifically, the space of the distribution line that can prevent the line failure and wire breakage accident due to the wire contact by maintaining a constant distance between the wires between the wire support points It relates to a holding device.

In general distribution lines, supports such as steel towers and long poles are installed to support the wires.However, the distance between the wires is not kept constant in the sections between the supports, that is, the long span, where the wires are in contact with each other. This may occur or be disconnected. Conventionally, in order to prevent such an accident, the long distance section is made of a wider band than the normal one, and the distance between the wires is farther away from the normal band, or an H-type pole is installed to separate the wires. Secured distance.

However, this method has to be different from the standard of the completion of installation in Changzhou according to the length of the span. Therefore, the uniformity of the installation in Changzhou can not be achieved, resulting in an increase in cost and a decrease in work efficiency in terms of material procurement and construction work. Even if the separation distance between wires is larger than the normal standard, the risk of track accident always existed because it is difficult to maintain the separation distance between wires stably regardless of the climatic conditions such as wind volume in the long span section.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a space maintenance device of a distribution line that constantly supports the separation distance between the wires so that the separation distance between the wires is kept constant in the long span section of the distribution line. It is done.

In order to achieve the above object, the present invention has first and second housings each having a hemispherical groove formed therein and hinged to each other so as to form a through groove through which an electric wire passes. A clamp having a crevis formed on a side of the first housing and an eye formed on an opposite side of the second housing; And a space between the clamps, the spacers having one end formed with a crevis at one end and the other end formed with a child at the other end so as to be coupled to the eye or the crevis of the clamp.

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

Referring to the drawings, the space holding device of the distribution line according to the present invention is installed between the clamp 10 for clamping the wire 1 and the clamp for holding the wire 2 to maintain a spacer 30 It is configured to include).

The clamp 10 is formed by hinged first and second housings 12 and 14. The first and second housings 12 and 14 are hinged to each other by fixing pins 22 at an upper side thereof. Hemispherical grooves 16 and 18 are formed in the housings 12 and 14. Accordingly, when the first and second housings 12 and 14 are engaged with each other, each of the hemispherical grooves 16 and 18 is coupled to each other to form a through groove which is clamped as the wire 1 penetrates in the longitudinal direction.

Sides of the first and second housings 12 and 14 form coupling parts to which the spacers 30 are coupled. Creses 24 are formed on the side surfaces of the first housing 12, and the second housing ( On the opposite side of 14, an eye 26 is formed. The eye 26 and the crevis 24 are positioned on the same line upon engagement, so that the ends of the spacer 30 are each engaged.

A coupling portion is formed opposite the hinge portion of the clamp 10, and the coupling portions are formed with flanges 27 and 28 in the first and second housings 12 and 14, respectively, and bolts are provided in the flanges 27 and 28. The ball is formed and secured by the bolt 4 and the nut 6 as shown in FIG. As a result, the bare wires or the insulated wires can be fixed after being arranged to pass through the through grooves.

The spacer 30 is formed of an insulator, and an eye 32 is formed at one end thereof, and a crevis 34 is formed at the other end thereof. The eye 32 of the spacer 30 is coupled to the crevis 24 of the clamp 10, the crevis 34 is coupled to the eye 26 of the clamp 10 and installed in the form shown in FIG. 4. The crevises 24 and 34 and the eyes 26 and 32 are coupled to each other by means of fixing pins 23 and 35 or bolts. This prevents the spacer 30 from moving or falling off.

The polymer suspension insulator is preferably used as the spacer 30. The polymer suspension insulator is an insulating part having a certain insulation ability in the air, and has a core made of FRP between both ends of the bracket where the eye 32 or the crevis 34 is formed. 36 is provided, and a plurality of ring-shaped insulators 38 formed of silicon or the like are formed on the outer circumferential surface of the core 36.

Referring to FIG. 4, when the present invention is installed, a distribution line space holding device is installed at a predetermined point in a long span section, and each of the distribution line wires 1 is clamped by being clamped by 10. The polymer suspension insulator, which is the spacer 30, is coupled between the clamps 10 clamping the respective wires to maintain the separation distance between the wires 1 and to ensure insulation between the power phases.

According to the present invention, the clamp 10 is firmly supported by the clamp 10, and a polymer suspension insulator, which is a spacer 30, is installed between the clamps 10, so that the wire is not dropped even by vibration of the wire 1 or the like. It is possible to produce and use the clamp 10 of different standards for each type of wire.

According to the present invention, it is possible to clamp the wires in the long span section between the wire support in the distribution line by the clamp, and to maintain the separation distance between the wires by coupling the spacers between the clamps, the wires to each other It is possible to prevent track failure such as mixing or disconnection.
