Description

Overhead Obstacles in Power Transmission Line {A Apparatus for Overcoming Obstacles in Power Transmission Line}

The present invention relates to an apparatus for overcoming transmission line obstacles, and more particularly, to an apparatus for overcoming a transmission line obstacle that can continue driving after passing through an obstacle while traveling on a transmission line of a single conductor and a multiple conductor type.

In general, overhead transmission lines are intended to send power generated by power plants to substations, including tracks, supports, insulators, and grounding devices. The overhead transmission line transmits the boosted power according to the increase of the transmission capacity, and uses the multi-conductor method which constitutes the transmission line by several conductors instead of the single conductor method which constitutes the transmission line by one conductor.

In the multiconductor mode, one conductor constituting the multiconductor is called a small conductor. In general, the multi-conductor method is used to make 2N (N: natural number) small conductors such as corridors (two small conductors), four conductors (four small conductors), and six conductors (six small conductors) constitute one overhead transmission line. do. In the ultra-high voltage transmission transmission line of 345kV or more, four- or six-conductor type is mainly used to increase transmission capacity and solve corona problems.

In such a transmission line, obstacles due to the temporary construction exist.

The obstacles include space dampers, suspension insulators, and people with disabilities. The space dampers are provided with vibration dampers for adjusting vibrations of the small conductors in a spacer for maintaining a constant interval between small conductors of a multiconducting overhead transmission line. In order to maintain the spacing between the small conductors and to prevent torsion and slip jumping, they are installed at regular intervals on the overhead transmission line.

However, since the registered patent is configured to move the obstacle overcoming mechanism by mounting the rail on one line of the processing line, there is a disadvantage in that the settlement of the obstacle overcoming mechanism is not stable.

In addition, when the rail part is composed of the first and second rail parts, and the two rail parts are seated on the processing land line, and an obstacle appears on the processing land line, any one rail part is separated, and only the remaining rail parts are connected to the processing land line. Although it is described that the obstacle is overcome by passing through the obstacle and re-seating while supporting the hanging, only one rail part is inclined by the weight of the obstacle overcoming mechanism in the state in which only one rail part is suspended from the processing line. Reaching the overhead line is a real challenge.

First, the up and down sliding motor 148 of the pair of driving parts 100 located in front of the drive the rotation of the pinion gear 146, through which the drive roller 112 in the vertical direction which is a direction to escape from the wire 114 is moved.

As such, when the driving rollers 112 and 114 move in the vertical direction, as shown in FIG. 10, since the driving part 100 is separated from the electric wire, an obstacle such as the spacer damper 4 may pass.

Subsequently, when the horizontal sliding motor 250 of the horizontal moving unit 200 is driven to rotate the pinion gear 240, the first rack gear 232 and the second rack gear (which are engaged with the pinion gear 240) are rotated. 234 moves from side to side to open the driving unit 100 from side to side as shown in FIG. 11.

In that state, two pairs of traveling parts 100 holding the electric wire travel and pass the obstacle.

After passing through the obstacle, the horizontal sliding motor 250 is driven in the opposite direction, so that the first rack gear 232 and the second rack gear 234 move in the opposite direction, and thus the driving part 100 that is opened to the left or right is opened. ) Is returned to its original position, and the up and down sliding motor 148 is also driven in the opposite direction so that the upper and lower driving rollers 112 and 114 can be remounted on the power transmission line 2a.

Thereafter, the pair of driving units 100 located in the middle are separated from the wire in the same manner as above. At this time, the four running parts 100 in the front and the rear run in a state of holding the wires so that the pair of running parts 100 located in the center pass through the obstacle.

Thereafter, the pair of driving units 100 located in the center may catch the wire again, and finally, the pair of driving units 100 positioned at the rear may automatically escape the obstacles through the order of avoiding the obstacles.

As described above, since the transmission line obstacle overcoming device 10 of the present invention is installed such that the traveling unit 100 formed of a pair of left and right forms three rows, two of three rows are paired in a state where the transmission line is seated on the transmission line. By sequentially passing obstacles, the driving unit 100 may pass through obstacles in the transmission line 2a.

The above description is only illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. In addition, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention.
