Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric power transmission line,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a corridor connection structure for a transmission line, and more particularly to a spacer function for maintaining a gap between a plurality of small conductors, a damping function for elastically supporting a small conductor, It has the function of marking and minimizes the influence of the wind to increase the stress generated at the connection between the steel tower, the insulator, the insulator and the small conductor, and to prevent the connection failure or dropout of the connection part. And relates to a corridor body connection structure.

Generally, the voltage developed in the power plant is distributed to the vicinity of the customer through the substation and the transmission line of various stages and finally through the distribution transformer and the distribution line, and is introduced into the customer through the lead line from the distribution line.

Distribution lines are divided into processing distribution lines installed on the ground and underground distribution lines installed on the ground.

The working transmission line according to the present invention is composed of a power transmission tower installed at a certain interval on the ground and a transmission power line supported in an insulated state through an insulator in a transmission tower.

Conventional transmission towers are classified into square towers, square towers, door towers, woofer towers, rotary towers, and MC towers according to their types. In Korea, square towers are widely used.

The rectangular steel tower is composed of a steel tower main body and three arms arranged on the upper part of the steel tower main body. The upper end of the insulator is supported at the end of the arm, and the machining power transmission line is supported at the lower end of the insulator.

Each of the arms is provided with a transmission line corresponding to each phase, and two transmission lines are formed on the left and right sides, one by one.

Here, the transmission line supported by each arm can be constituted by one conductor or by a corridor (multi-conductor).

In the case of using an aisle body, it is necessary to install a shunt reactor in order to prevent the parity phenomenon, and there is a disadvantage that a spacer is required to prevent collision between conductors, but the inductance is decreased and the working electrostatic capacity is increased There is an advantage of increasing the allowable current, increasing the transmission capacity, increasing the stability, preventing the corona, increasing the corona threshold voltage, and lowering the potential hardness of the wire surface.

A transmission line using a conventional corridor constitutes a transmission line by using a plurality of small conductors. The transmission line includes 2 corners (2 conductors), 4 conductors and 6 conductors in order of 2N (N is a natural number) . At this time, the spacer damper is provided with a spacer for keeping the interval of the small conductors of the corridor transmission line constant, a damper for connecting the clamp and the spacer for fixing the small conductor, and preventing vibration.

These spacer dampers maintain the spacing between the small conductors and are essentially used at certain intervals.

Conventional airborne fault lamps are installed in the transmission tower, and it is difficult to identify the transmission line at night, and there is a risk of safety accidents of aircraft, workers, or the general public.

As a prior art for solving such conventional problems, Korean Patent Registration No. 10-1064705 (published on Sep. 14, 2011) discloses a spacer damper comprising a plurality of clamps for fixing small conductors, a current induction portion formed inside the clamps, A power supply unit connected to the current induction unit to receive the induction current induced from the current induction unit to generate a power source, and an air fault lamp to be turned on by a power source supplied from the power source unit, And it is possible to identify a transmission line at night to prevent a safety accident of an aircraft, a worker, or the general public.

However, the prior art includes a spacer vertically installed with a constant area, four clamp arms extending vertically and horizontally at 45 degrees in the vertical direction, and a clamp installed at an end of the clamp arm to clamp the small conductor, An air obstacle lamp and a power source are installed in a spacer, and the sintered body is tensed or vibrated by the wind which is caught by the spacer, the air obstacle lamp, and the power source, and the stress generated at the connection portion between the steel tower and the insulator, As a result, there is a problem that connection failure or dropout occurs at the connection portion.

Therefore, it is possible to minimize the influence of wind while providing a spacer function for maintaining a gap between a plurality of small conductors, a damping function for elastically supporting the small conductor, and an aviation obstacle mark function, It is required to develop a technique for increasing the stress generated in the connection portion and preventing the connection failure or dropout of the connection portion.
