Description

Power cable space for power transmission tower

The present invention relates to an interphase space for a transmission line, and more particularly, a transmission between a transmission line having a different height on the same vertical line and a transmission line interposed therebetween to maintain a tensioned state of the tension of the transmission line by adjusting a gap therebetween. By improving the structure of the interphase space for overhead lines, the components can be simplified to reduce manufacturing costs and improve construction convenience, while minimizing their own loads to prevent sagging of transmission lines caused by structures installed on transmission lines. It relates to the interphase space for transmission line.

In general, electric power is transmitted from a power plant to a substation through a transmission line supported by a steel tower and the like, and is supplied to general consumers (homes) along a distribution line of Jeonju after several stages of transformation.

The shape of the steel tower used as a support for such a transmission line depends on the transmission power, voltage, and topography of the line, and the main material is steel having an L-shaped cross section. In addition, the horizontal cross-section of the pylon is often square, and thus the foundation is also produced through the concrete curing process at the vertex of the square (頂點).

Usually, the pylons of power transmission lines support three-phase, two-wire, or six wires with insulators, and the distance between the pylons is 20 to 30 m. It is.

In addition, when crossing a wide river or a deep valley, the span is long, and thus the tension of the electric wire is increased, so a particularly strong structure is required. Even if it is a transmission line, it is a small one, or a pontoon built on a single foundation as a support for a distribution line or a telephone line.

have.

These transmission line pylons connect a plurality of transmission lines to each other, and these transmission lines are installed under high conditions such as vibration or amplitude due to climatic influences such as wind or snow rain due to the characteristics of being installed at high altitudes. In order to solve the problem, conventionally, a spherical weight, that is, a weight, was installed at regular intervals of a transmission line to prevent the transmission line from shaking due to the influence of the climate.

However, it is clear that the above-described conventional technology can be expected to be easy to install, but as mentioned above, simply hanging weights individually for each transmission line has a limit to effectively prevent up and down shaking between transmission lines.

Accordingly, recently, a collision between transmission lines using a folding clamp connected to power transmission lines, a rod body connected and supported between the folding clamps, an insulator tube attached to the rod, and a plurality of wing plates is provided. Was to prevent.

However, the conventional invention configured as described above has various problems in the use of the bar. First, it is designed to receive a lot of wind resistance due to its external structure, which causes a severe shaking phenomenon. That is, because a severe resistance phenomenon between the wind and the wing plate is caused. Second, there is a problem that the structure is made of a rather heavy load causing a change in the tension of the transmission line causing the transmission line sagging phenomenon.

Therefore, the situation is actively developing the phase spacer for the transmission overhead line to prevent the vertical shaking between the transmission and distribution.

Such a technology related to a phase spacer for a conventional overhead line has been disclosed through Korean Patent No. 10-0865074, and FIG. 1 is a cross-sectional view of a main part of the phase spacer for a transmission overhead line disclosed in Korean Patent Registration No. 10-086074.

The front and rear upper and lower portions of the spacer 20, the left and right vertical support plates 30 and 30a for guiding the lifting and lowering of the upper and lower end line spacers 10 and 20 from the left and right, and the left and right vertical support plates 30 and 30a are blocked to prevent the inflow of foreign substances. It includes a front and rear sealing plate (not shown) and a plurality of accessory components for operation and assembly thereof.

However, the conventional interphase spacer for overhead lines has a complicated structure, which makes it difficult to require high construction costs and construction, and also improves the structure for reducing the load. There was a structural problem that the effect is significantly lowered.

The present invention has been made in view of the above-described problems, the purpose of which is interposed between the transmission line and the transmission line having a different height on the same vertical line, the transmission processing so that the tension of the transmission line to maintain the tension between the transmission line between them By improving the structure of the interphase space for the track, the components can be simplified to reduce the manufacturing cost and improve the convenience of construction, and to minimize the self-load so as to prevent the sagging of the transmission line caused by the structure installed on the transmission line.
