Description

Distribution line with optical fiber composite neutral line for communication network construction in overhead neutral line distribution line that combines overhead line and extra high voltage neutral line

The present invention is a special high-pressure processing neutral ground wire installed in a position to secure the lightning shielding angle of the high-voltage power line by using a combination of the overhead line and the special high voltage neutral wire that serves as a return of unbalanced current and fault current in the distribution line The present invention relates to a distribution line capable of simultaneously performing an optical communication line for constructing a communication network. More specifically, a fiber optic composite neutral line is installed at the top of a pole without the construction ground line, the neutral line, and the optical communication line. And processing lines, which can serve as communication lines as well as expanding the range of use, while reducing the cost of construction costs and simplifying the lines to reduce the load on the supporting equipment. Optical fiber for communication network construction in overhead neutral cable distribution line It relates to a distribution line having a neutral complex.

As electricity is an essential means of our lives, with the development of civilization, modern society demands high-quality electric power in the times, and the instantaneous power failure as well as the work interruption causes great inconvenience to people's life and corporate production activities. Doing a power outage

The national level is trying to prevent it.

As part of these efforts to prevent blackouts, the average blackout time per house in the country has been greatly reduced from 100 minutes to 19 minutes per year. Became,

Second, power outages due to poor equipment have been greatly reduced by the development and supply of high quality materials.

Third, the blackout accidents caused by lightning strikes were established and operated by the Korea Electric Power Corporation's Design Standard [3800] Distribution Line Landing Standard, which prevents lightning strikes of the distribution lines to prevent lightning strikes. Based on the installation of overhead lines, the installation was largely solved by installing lightning arresters and the like in order to increase supply reliability.

Fourth, other blackout accidents are caused by natural disasters such as typhoons and floods, poor customer equipment, public error, worker error, and unknown reasons.

As enumerated above, it can be seen that there are still many cumulative problems to be solved in order to prevent a power failure.

First of all, KEPCO established the distribution line tolerant standards for improvement of power quality, and to protect the distribution lines from mines as well as direct lightning strikes to prevent lightning strikes on the distribution lines. It was implemented by changing the installation of the processing ground to the basic, but in order to construct additional processing ground on the existing distribution line, it was unavoidably relayed to the entire circumference (extended by enclosing the pole and the complete) to install the processing ground. By developing branch supporters (small steel sheets) and continuing to use the method of connecting poles, if the finished steel sheets or steel sheets lack the basic safety factor, they should be reinforced to ensure the safety ratio by branch lines, but it is not sufficient. There is a vulnerability that easily collapses in a disaster.

This is not only the situation of using rags or dolls' old-fashioned construction methods, which were used in times of difficulty in the difficult environment of the economic development era where funds were lacking in the past, as rags, even in economical times. Even the support has been developed and applied to the electric cable line, but the complete straight pole has a limit to fail to secure the lightning protection shielding angle.

In addition, foreign contact accidents and unknown causes that occur during the blackout's spawning period account for about 43% of total failures.However, despite efforts to prevent accidents, accidents are not reduced. The method of reversing the protection of the environmental ecosystem and the construction method of distribution lines (aka LHC method, down jumper construction) are also expanding the hazardous facilities due to indiscriminate construction without sufficient scientific review. By disposing of possible demolition materials unconditionally, it not only wastes resources but also pollutes the environment.In the 22.9KV multi-grounding method, processing ground wire and neutral wire are connected to each other every week. The overhead line equipment not only increases the load on the support, In addition, it is vulnerable to natural disasters due to unstable power facilities due to the relaying method and there is a problem in securing the ground height of the support.

Looking at the conventional electric pole and the distribution line using the same as shown in Figure 1, as shown in Figure 1, the processing line support 22 is installed on the top of the pole 28, the lower side having a plurality of insulators 24 ( 23) is installed, and a plurality of poles (1) having a rack 26 is installed on the bottom of the ground, and the processing branch line 21 is connected to the upper end of the processing line support 22 by a jump line 27, The insulator 24 of the 23 is connected to the power line 25, the rack 26 is a combination of the neutral wire 20

Referring to the problems of the conventional electric pole constructed as described above and the power distribution method using the same in detail as follows.

Firstly, unstable bird failure avoidance construction makes power facilities vulnerable and damages to natural disasters are explained in detail.

According to various engineering and scientific grounds, Korea's power distribution line established the design standards for power distribution field from July 1, 1975 to secure the construction quality and to design, construct, and inspect to fully endure natural disasters. The strength of concrete column and finished steel used as support of cable line is to select proper design load according to outer diameter, span and wind pressure load of reinforcement line. That is, in this case, consideration should be given to the increase in the outer diameter of the electric wire due to the future line increase, the length, and the insulation, and to adopt the load of the part of the load that causes a large stress on the member. .

In the case where wind pressure is applied in the direction perpendicular to the wire, the vertical load and the horizontal lateral load are applied simultaneously.In the case where the wind pressure is applied in the direction of the wire, the vertical load, horizontal longitudinal load and horizontal angular load are applied. At the same time, when the arrangement of the subwire is asymmetrical in the support, the vertical eccentric load must be added, and the load due to the torsion (torsional force) must be added to the human and internal columns, and various loads are applied to the cable line. .

In addition, the conventional construction method has a problem of rising construction cost due to overlapping investment due to parallel operation of the processing ground wire and the neutral wire every week, the same function as the following reasons.

Based on the installation of overhead lines, the current overhead line is installed on the top of the pole, and the overhead line of the distribution line to prevent lightning strike of the distribution line is protected. The shielding angle is 45 °, and the distance between the long span and the place where there is a fear of mixing is increasing the separation distance. It is relayed and constructed.

The ground of overhead wire is shared with neutral wire within 200m, and grounding resistance is less than 50Ω, and the overhead wire and neutral wire are connected to each pole.

Here, it can be seen that the processing branch wire and the neutral wire are used in common.

The multi-grounded neutral wire of extraordinary high pressure (or high pressure) is shared with the low voltage neutral wire of the same system or the ground side wire.In this case, the thickness of the common neutral wire is the larger of the extra high neutral wire thickness and the low pressure neutral wire. Since it can be used as a neutral cable, the cost of construction is rising due to overlapping investment in distribution lines with the same function.

On the other hand, in order to solve the above problems, the applicant of the present invention, such as patent registration No. 10-0725382 has applied for a pole pole with a processing ground wire combined processing neutral ground wire and a distribution method using the same,

Through this, the poles can be used as a single power line without the risk of overvoltage and heavy current caused by the direct brain, and the overhead line can be used as a neutral wire to reduce construction costs and simplify the line. The load was reduced and the ground clearance of the neutral wire was eliminated.

On the other hand, in the modern electric power business, the demand for the construction of the power company's own information and communication network is increasing due to distribution automation and smart grid.In response to this demand, the communication line is allowed to each telecommunication company in Jeonju to provide a separate communication line to the distribution line. The utility company leases the installed communication line and uses it as its own information network.

However, the construction of the communication line as described above requires the construction of another communication line separately from the processing ground line and the neutral line, which causes the fatigue of the distribution line due to the increase of the distribution line fatigue due to the communication processing equipment exceeding the load of the distribution line. Accidents occur frequently, and also increase the cost of construction and hinders the aesthetics of the city, and in particular, the distribution operators pay a separate charge for the distribution line automation telecommunications carriers.

The present invention has been made in order to solve the above problems, by installing a high-voltage processing neutral wire and an optical fiber composite neutral wire compounded in the optical communication optical fiber is installed at the top of the pole, the role of the neutral line and the processing branch line Of course, the use of optical communication lines can be expanded at the same time, and the scope of use can be extended, and the cost of construction and the simplification of the lines can be reduced to reduce the load of supporting materials, thereby preventing the breakdown of poles. By renting optical communication lines to telecommunications operators, it is possible to generate large profits, and by securing its own network, it is possible to reduce the lease cost of communication lines, thereby processing overhead lines that combine high-voltage neutral lines with overhead lines that enable high value-added power facilities. Provides a distribution line having a fiber-optic neutral cable for establishing a communication network in the distribution line It is an object of the present invention.

In addition, in line with the trend of modern society, where the demand for power facilities is increasing and the demand for advanced information communication networks is increasing due to advanced IT, processing overhead lines and special features that enable excellent information transmission without any confusion and loss are possible. Another object of the present invention is to provide a distribution line having an optical fiber composite neutral line for establishing a communication network in a processed neutral branch line distribution line that also serves as a high-voltage neutral line.

In a specific means for achieving the above object, in the distribution line is installed with a complete insulator with a plurality of insulators connected to the power line,

At the top of the pole, a fiber-optic composite wire serving as a processing ground wire, a neutral wire, and an optical communication line is installed by the composite line support.

This can be achieved by installing a composite line support so that the insulator and power line are positioned within the lightning protection shield angle of the fiber optic neutral cable during a lightning strike.

As described above, by constructing a distribution line having an optical fiber composite neutral line for constructing a communication network in a processing neutral branch line distribution line which combines the processed ground line and the special high voltage neutral line of the present invention, the use scope is expanded and the cost of construction is reduced and the line is simplified. By reducing the load of the furnace support, it is possible to obtain the effect of preventing the breakage of the pole.

In addition to the automation of distribution, it is possible to generate large profits by improving the urban aesthetics and leasing optical communication lines to telecommunications operators. Also, it can reduce the lease cost of communication lines by securing its own communication network, thereby increasing the added value of distribution lines. You can get it.

In addition, in line with the current trend in which the demand for power facilities is increasing and the demand for advanced information and communication networks has been increased due to high-tech IT, it is possible to obtain an effect capable of delivering excellent information without any confusion and loss. .
