Figure 7 is a perspective view of the support of the present invention.

The present invention relates to a large polymer insulated arm for transmission line connection.

The construction of power transmission facilities is inevitable due to the continuous increase in electric power demand and regional imbalance of electric power production and demand.However, securing the transition point for power transmission lines due to land price increase and Nimbi phenomenon has already emerged as the biggest issue in the electric power industry. Compensation and construction costs are expected to increase significantly. Since the existing transmission line is a negative factor in the urban aesthetics and land development, it is required to improve this and to introduce a new environmentally friendly transmission equipment technology capable of large capacity transmission.

Accordingly, the compact tower to which the insulation arm using the new polymer material such as the present invention is applied can be lightened and miniaturized, and the appearance is beautiful and the transit tower is less, and the transmission tower is already in use at a high voltage. It has been found that the efficiency and economic effect of boosted power transmission is easy to increase power transmission capacity.

In addition, by compactizing the size of the transmission tower using a polymer insulated arm, construction costs such as material costs and labor costs, paper purchase costs, and maintenance costs due to not using rock materials can be reduced. The expected effect on the economic side is expected to be huge.

That is, in the above-mentioned compact tower, the arm for maintaining the space between the tower and the conductor is replaced by the insulating arm of the present invention instead of the conventional steel arm, and in this case, performs the insulation function performed by the insulator in the existing tower. As a result, the existing form of insufficiency becomes unnecessary.

In addition, if a polymer insulated arm is applied (the main material of the steel tower is steel), it is not necessary to insulate the arm, so the bracket is composed of a minimum device for fixing the arm insulator that holds the wire, so the length is very short. Lose. In addition, in the arrangement of the wires, the arrangement is the same without the distinction between the suspension type and the built-in type.

In summary, the existing transmission towers are seriously causing the problem of increased pollution of the insulator due to the smoke and dust due to overcrowding of the city, and most of the domestic transmission towers are located in the mountainous area, which leads to forest deactivation. Due to the great difficulty in securing the land insulation distance due to the problem, and the problems caused by the reduction of the transitional area near the city center of the narrow country and the high land, there are great difficulties in the operation of the new wire line. This makes it possible to reduce the size and weight of the transmission tower, which reduces not only the unit cost but also the material transportation, installation and construction costs by about 30%, and the construction of the transmission tower is simplified and the weight is reduced to make the appearance beautiful. Not only does the tower's durability increase significantly, but it also reduces maintenance and repair costs. A power transmission tower, which is used as it used to have the characteristics such as the voltage step-up transmission becomes possible in the transmission voltage.

On the other hand, the inventor of the present invention has been registered as a patent registration No. 10-1041666 by applying for a polymer insulating arm having the characteristics and advantages described above, the patent claims;

Two sets of main insulations are formed on the entire outer surface of the FRP mandrel, in which silicon rubber layers with large and small diameter insulating shades are alternately protruded, and the connecting brackets are crimped and fixed on the left and right sides, and are horizontally fixed to the existing transmission tower by a clamp. Cancer;

A silicon rubber layer is formed on the entire outer surface of the FRP mandrel, which is formed by alternately protruding moldings of large and small diameters, and the left and right connecting brackets are crimped and fixed to the existing transmission tower by means of clamps and turn-buckles. Two sets of auxiliary insulated arms supporting the grass;

A connection bracket for impact mitigation, which is connected between a connection bracket of the auxiliary insulating arm and a turn-buckle fastened to each other, and a hole through which a fixing pin for fixing the connection bracket and the turn-buckle passes;

A vertical plate having a hole for assembling the connection bracket of the auxiliary insulation arm with a fixing pin, a hole for fixing the connection bracket of the main insulation arm with a fixing pin, and a hole for fixing a known power line connection device Supporters with horizontal plates;

A fastening ring for impact mitigation, wherein fixing ends having a hole through which a connecting pin of the auxiliary insulating arm and a fixing pin for fixing the supporting bracket pass are formed;

Two projection pieces which are assembled with the horizontal plate of the support and have holes for fixing with fixing pins, and are formed integrally with the center of the opposite side of the protrusions to fix the connection brackets of the main insulating arm with fixing pins. The branch is made of a polymer insulating arm for transmission line connection, comprising an auxiliary tool for mitigating impact having another projecting piece.

It provides a polymer insulation arm that seeks to reduce the weight and size of the three-dimensional solid structure, so that the existing transmission tower can be used as it is and its durability and quality are excellent. It is possible to reduce the cost of transportation and installation of materials by reducing the weight and size of the products. It is also economical. As a result, the reduction of maintenance and repair costs is not only a big advantage, but also considering the use of land use efficiency and the purchase of transmission tower construction site, it has proved to be a useful effect that can generate economically large profits at the national level. However, because the size is small, the user is large It has the following problems were found when requested polymer insulation cancer.

That is, the main insulated arm of the pre-registered patent uses an FRP mandrel 11 having a length of 1959.5 [mm] and a diameter of Φ 80 [mm], and the insulated shade formed on the FRP mandrel is an alternating shade and a large shade is Φ 210 [mm]. ] And 17 small shades are used for Φ172 [mm]. The insulation distance of the main insulation arm main body designed as such is 4,750 [mm] and dry flash distance (air insulation interval) 1,699.5 [mm], so that sufficient insulation distance is maintained. The auxiliary insulation arm is also designed under the above conditions. The rod diameter is 34Φ and the length is slightly shorter than the main insulation arm.

However, in order to configure the large polymer insulating arm of the present invention as shown in FIG. 1, the length of the main insulating arm 20 should be about 5 meters, and the length of the main insulating arm of the pre-registered patent and the length of the auxiliary insulating arm 5 Increasing the inside and outside of the meter, the central portion of the main insulation and secondary insulation arm with heavy load sags, and applies a very large pulling force to the support fixed to the transmission tower, which becomes unstable and violently shakes up, down, left and right by the wind. There is no way to prevent the problem that can not be used as a preferred insulating cancer occurs.

It is therefore an object of the present invention to provide a polymer insulated arm that has a novel structure and solves a structural strength problem as a large size, based on Line Registration No. 10-1041666.
