Description

Electric pole with lightning protection and eco-friendly function and power distribution method using it {Pro-environmatal electric pole safe from lightening and distributing method using the same}

The present invention is to install a neutral wire at the top of the pole without installing a separate processing wire, so that the role of the processing ground can be performed at the same time, to extend the range to be protected from lightning, and there is no risk of power failure accident By providing a nesting space for bird nests, it is transformed into a breakthrough environment-friendly power distribution facility that can protect insulators and power lines from lightning strikes, prevent foreign contact accidents, minimize waste materials, and recycle waste resources. The state relates to electric poles with lightning protection and eco-friendly functions, and power distribution methods using the same.

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. As a result, national efforts are being made to prevent power outages.

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

First, work outages, which accounted for the largest proportion, were solved by the development and application of the method.

Second, power outages caused by poor press release have been greatly reduced by the development and supply of high quality materials.

Third, the blackout caused by external contact, which has been resolved somewhat by the insulation of the track and simple tide avoidance type (jumper downlink and LHC construction method) and relief (驅除: how to shoot magpies). It is assumed that it is the cause of the cease-fire, and the complaints of environmental protection organizations cannot be ignored.

Fourth, a blackout accident caused by lightning strikes was established and operated by the Korea Electric Power Corporation's design standard [3800] distribution line tolerant standard [provisional]. The direct lightning protection was based on the installation of overhead lines, and in order to increase the reliability of supply, the installation of lightning arresters and the like was greatly solved.

Fifth, other blackout accidents are caused by natural disasters such as typhoons and floods, customer equipment defects, public errors, worker errors, 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.

Among them, the first is that the reality of having to fight the war with magpies and the fact that most of the accidents are unknown are estimated to be foreign-contact accidents caused by birds. The installation of the support and the wire is in a situation where structural dynamics are exposed to natural disasters such as typhoons and floods due to incomplete load eccentricity or construction beyond the lightning protection angle.

Second, KEPCO enacted the distribution line tolerant standards for improvement of power quality, and processed the mines as well as direct lightning strikes to protect the distribution lines from lightning strikes to prevent lightning strikes on the distribution lines. It was implemented by changing the installation of the ground wire to the basic, but in order to construct additional overhead wire on the existing distribution line, it was unavoidable to relay the wires around the circumference (extended by tying the poles and the complete wire) to install the overhead wires. Small steel plates) are developed and used continuously to connect the poles. If the finished steel sheets or steel sheets lack the basic safety factor, they should be reinforced so that the safety factor can be maintained by branch lines, etc. There is a vulnerability to collapse.

This is not only the reality of using the step-by-step or puppet old-fashioned construction methods, which were used in times of difficulty in the difficult environment of the economic development era in which past funds were scarce, but also as rags in the economically present day. Although it has been developed and applied to the electric cable line, it requires a more robust and perfect method to solve all of these problems, such as the limitation of not being able to secure the lightning protection shielding angle in the complete cable owner.

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 the demolition materials unconditionally, it not only wastes resources but also pollutes the environment.In the 22.9KV multi-grounding method, overhead wires and neutral wires are being invested in the same function, which increases the load on the support with unnecessary overhead wires. Rather, it is unstable power facility due to relay construction. Vulnerable to disasters, and there is a problem in the ground to secure the support.

Looking at the conventional electric pole and the distribution line using the same as described above, as shown in Figs. 4 and 5, the processing line support 22 is installed on the upper end, the lower portion 23 provided with a plurality of insulators 24 ) Is installed, a plurality of poles (1) having a rack (26) is installed on the bottom of the ground, and the processing line support 21 is connected to the processing line support 22, the insulator (24) of the stub 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 (wire under tension). 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, if 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 pillars. It's working.

1. Vertical load

A) the weight of the main body, cast iron, insulator and

B) If the vertical angle is large, the vertical component of the line tension

C) Vertical component by branch tension

2. Horizontal Lateral Load

A) wind pressure on the main body, insulator and substation line;

B) The horizontal lateral force produced by the assumed maximum tension of the subsurface when there is a horizontal angle in the line (hereinafter referred to as the horizontal angular load).

3. Horizontal longitudinal load

A) wind pressure applied to the main body, insulator and steel

B) non-average tension equal to the assumed maximum tension

C) the mean tension of one-third of the maximum tension assumed

D) in the reinforcement column, the average tension of 1/6 of the maximum tension assumed

However, the jumper wire down pole and LHC [LONG, High, Cover] construction methods are all used for the purpose of simply preventing external accidents caused by algae without considering the effects of various loads. Although it is applied to the distribution line, when constructing the subsidiary line asymmetrically, although additional reinforcement is required for more kinds of loads, it is constructed without considering this, so that the very weak distribution line is made throughout the country, such as typhoons and floods. Natural disasters are easily collapsed and devastatingly damaged, resulting in large national economic losses.

In addition to the foregoing, excellent new equipment has been developed in an effort to prevent power failure due to poor distribution equipment, and the existing suspension and line port insulators have been replaced with newly developed materials. Although possible, there is a problem in that waste is disposed of and environmental damage and resources are wasted.

In addition, the conventional simple bird failure avoidance type pole installation has been derived for the purpose of simply preventing the external contact due to the algae without considering various loads, the following problems were derived.

First of all, in order to construct the jumper line downward as a problem of eccentric load, it is impossible to install the suspension insulator in the center of Jeonju. There are frequent accidents that come into contact with Jeonju due to winds such as typhoons, passing downward close to the side of the bridge. Especially, in case of the two-stage track, the distance between the top and bottom is not enough, so the installation is larger than the standard distance. Additional poles should be installed.

Secondly, LHC [LONG, High, Cover] construction method is applied to all distribution lines as the representative of simple avoidance type, but this is because the subsidiary line is constructed asymmetrically. Construction farther from the support increases eccentric loads and torsional loads, and distance increases the difficulty of manpower construction.There is a risk of safety accidents.The jumper wires are constructed higher to escape the shielding angle of the processing line and adversely affect the horizontal load. Increasing the construction cost by using Jeonju as a heavy load while increasing the difficulty of construction and construction, and increasing the construction cost due to the indiscriminate Kabaryu construction, which makes it difficult to check the track maintenance.

Third, as a new developer material, the use of a single built-in block for preventing bird failure is not a simple avoidance method but an active avoidance method. It contains all the problems listed above. Serious problems that require changes to all material standards and the owners of the materials are heavy and difficult to work, which leads to risk of safety accidents and does not consider various loads on the cable line, resulting in national budget waste and enormous losses.

In addition, the conventional construction method has the problem of rising construction cost due to overlapping investment due to parallel operation of the wire of the same function, for 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 lines of the distribution line to prevent lightning strikes on the distribution lines are 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 the overlapping investment of distribution lines with the same function.

In addition, the problem of destruction of the natural ecosystem occurs due to the magpie relief mobilized by the leaves.

In 2000, the magpie, the legendary magpie that delivers good grace, and the magpie that delivers the good news, was designated as an ideological assistant by the Ministry of Environment. This can lead to obvious environmental ecosystem destruction.

What is clear is that when humans destroy nature, they are devastated without knowing.

In the power facility management agency, the magpie kills magpies with its own hunters and receives hunting permits, and carries weapons and kills anytime and anywhere immediately regardless of the hunting period and location throughout the year. Accidental deaths occur in some areas, poaching in some areas, caught by prosecutors and investigated, and there is always a dangerous and social spread.

The following describes the problems in terms of power facility management agency of the conventional distribution method.

The L.H.C. method is an environmentally exclusive distribution method for avoiding tide of birds, and the following problems have been derived by constructing them exclusively for the purpose of simply avoiding foreign contact accidents caused by algae without considering various loads on the cables.

First of all, in order to construct the jumper line downward, the torsion insulator hangs eccentrically to one side in the center of Jeonju. Due to the lack of separation distance between the upper and lower ends of the single track, the Jeonjujang is bigger and a heavy load electric pole must be installed.

Secondly, in the state where the arrangement of the subwire is asymmetrically constructed, the subwire is constructed farther from the support, thereby increasing the eccentric load and the torsional load and increasing the distance.

Thirdly, the method using LP No. 3 pin has a problem of exceeding the lightning protection shield angle of the processing ground wire, which not only escapes the processing ground lightning protection shield angle by constructing the jumper wire higher, but also withstands horizontal horizontal load and becomes dangerous. The construction cost is increased due to the bad impact such as reinforcement with the thick and heavy LP4 hoffin and increasing the construction cost by increasing the difficulty of construction, and increasing the cost of construction by indiscriminate construction of the tracks. There is a problem with ascension.

In particular, the construction method of distribution lines (aka L.H.C construction, down jumper construction) is constructed indiscriminately without scientific review, but rather, it is making double investment for expansion of risk facilities and maintenance.

The present invention has been made to solve the above problems,

By constructing electric pole that can use processed ground wire and neutral wire as a single power line, it also serves as a neutral wire, reducing the cost of construction cost and simplifying the line by reducing the cost of construction and eliminating the ground height of the neutral wire. Forming a bird nest space part in an environment-friendly way, and installing a bird nest induction pin on the lower power line leads the bird nest to the farthest and safest place from the power line to prevent bird outages while protecting birds and recycling suspended insulators that are disposed of waste. It saves resources and prevents environmental pollution, and prevents accidents caused by lightning strikes by securing a safer and more convenient lightning protection shielding angle, and provides a solid power distribution facility and external contact against natural disasters such as typhoons and floods. Lightning protection and eco-friendly to prevent unknown power failure A pole and distribution method using the same having the function there is an object of the present invention to provide.

When the distribution line is wired using the electric pole of the present invention configured as described above, the rack 11, 2c, and 2d in the upper part of Fig. 2a is composed of 8, and Fig. 2a neutral wire support (3) and Fig. 2b neutral wire support ( 3 ') or FIG. 2c neutral pole support (3 "), the pole is provided with a plurality of insulators (7) and a bird (6) provided with a bird nest guide pin (9) (9') A large number of (1) is installed on the ground, and the neutral wire support (3) (3 ') (3 ") at the top is connected to the neutral wire (2) to simultaneously perform the roles of the processing ground wire and the neutral wire, and the completion (6) The power line 5 is connected to the insulator 7 on the upper part, and the power line 5 and the insulator 7 of FIGS. 2A, 2B, 2C, and 2D are installed, but the lightning protection shield angle of the neutral line 2 is shown in FIG. 3. Lightning protection and eco-friendly functions, which can be constructed according to the shape of the complete (6) and insulator (7), neutral wire support (3) (3 ') (3 ") so as not to escape the (??) Boat using electric pole It is a major method.

When the electric wire is installed using the electric pole constructed as described above, since the neutral wire 2 connecting the top end of the electric pole 1 plays the role of the conventional processing ground wire as shown in FIG. In addition to reducing the cost of materials, it prevents contact accidents between jumper wires and poles, eliminates eccentric and torsional loads, and makes construction easier and safer and eliminates the risk of accidents.

In addition, as shown in Fig. 2a, a nest-inducing pin 9, 9 'with a plurality of pins protruding on the outer circumferential surface is provided on the finishing 6, on which the power line 5 is installed, or as shown in Figs. 2b and 2c. By installing the bird nest guide pins (9) and (9 ') in the finishing (6) where the power line (5) is installed, and forming a bird nest space part by the finishing (8) in the neutral wire connection, there is no risk of power failure By providing a space for birds to nest in a safe location, the birds can be protected and at the same time, the bird's nest guide pins (9) and (9 ') can be prevented from momentary power failure due to foreign contact. To ensure that

On the other hand, the electric pole of the present invention as shown in Figure 3, the insulator (7) and the complete 6, the power line 5 is installed is spaced apart by a distance that can be protected by the neutral line (2) during lightning strike and conveniently adjusted Because it can be installed, the power line can be safely protected even during lightning strikes to prevent power outages.

Hereinafter, the operation and effects of the present invention will be described in detail.

The current distribution line is connected to the processing line and the midline, so it is the same as if it is directly hit by the neutral line even if it is directly hit by the processing line. The ground connection shall be disconnected and all grounds shall be separated from the neutral ground and overhead ground.

However, although the processing ground wire and the neutral wire of the distribution line formally share the roles of lightning protection, special high pressure neutral wire, and low pressure neutral wire, they are electrically operated in parallel but differ in their positions. Since the existing neutral line is installed at the processing branch line and the processing branch line is replaced by the neutral line, there is no problem in the electric technology even if the track is operated by the processing line and the neutral line.

Therefore, at present, distribution lines and neutral lines are interconnected and shared by every pole, so the facility is doubled. When the neutral line is wired to the processing line position, the neutral line acts as the processing line line and the neutral line to reduce the cost of construction cost. And the simplification of the track reduces the load on the support and eliminates the ground clearance of the neutral wire.

In addition, unlike the existing methods such as blackout accidents caused by magpies, which occupy 43% of momentary power failures and temporary failures, and removal of magpies by mobilizing personnel, the present invention is an intelligent environmentally friendly power distribution method. By intelligently interpreting the characteristics and selecting the most favorable place when the magpie nests, the neutral wire is grounded and irrelevant to the blackout accident. It provides an environment.

In addition, the poles of the lower power line should be constructed as a solid standard pole which is not eccentric in load, but the phases on both sides will be lowered by the jumper, and the center phase will be constructed by bypassing the end of the finish and the nest guide pin (9) Install a pin and install a BAP (Bird Accident Protect) plate on the suspension or polymer insulator in the middle to prevent the bird's nest from contacting the power line and lead it to a safe place. It is less than%, but it prevents power failure even if nests near power lines do not occur.

In addition, the present invention is a reusable suspension insulator due to the development of the polymer suspension insulators and is a waste of resources and environmental pollution to encourage the use of discarded suspension insulators in the neutral wire and also to develop a conventional insulator by using the same It can be used as a substitute for insulators, reducing waste of resources, reducing material costs, and improving material quality.

As described above, the present invention constitutes a pole that can be used in common with the processing ground wire and the neutral wire, and serves as the processing ground wire with the neutral wire to reduce the cost of the construction cost and simplify the track, thereby reducing the load of the support and eliminating the ground height of the neutral wire. Of course, it provides environment-friendly bird nesting space on the neutral line and installs bird nest induction pin on the lower power line to guide the bird nest to a safe place where there is no danger of contact with the power line to prevent the power failure and protect birds. It can save resources and prevent environmental pollution by recycling suspended insulators that are disposed of waste, prevent accidents caused by lightning strikes by securing a more convenient and safe lightning protection shield angle, and prepare for natural disasters such as typhoons and floods. It is possible to prevent unknown power failure due to a solid power distribution facility and external contact. It is a miracle that effect.
