Generally, the current generated in a power plant is converted into a high-voltage current suitable for transmission in a substation, and then transmitted through a transmission transmission cable supported in an insulated state via an insulator to a transmission tower installed at regular intervals on the ground.

The transmission tower is installed in a standard tower which is used for standard span according to the length of the span (the distance between the support points of the wire between the tower and the tower) and in a place where it can not be used other standard tower And special steel towers.

Standard steel towers are divided into rectangular steel towers, square steel towers, gantry towers, woofer steel towers, revolving steel towers and MC (Motor Columbus) steel towers.

Also, it can be divided into straight tower, angled tower, anchor tower, and strain tower depending on the purpose of use.

In Korea, rectangular steel towers designed to have the same strength of the steel towers in the direction of the cable track are used mainly among the standard steel towers to be applied between the short diameter because they are easy to design and have a high degree of safety.

Hereinafter, a process of connecting the working transmission cables L1 and L2 and the wire ropes 30 and 40 by the corridor body fixing device for the working transmission line according to the present invention will be described.

The fastening bolts 54c and 64c of the fastening means 54 and 64 are disengaged from the bolt fastening holes 54b and 64b and taken out from the bolt through holes 54a and 64a as shown in Figure 5 (a) The first connection plates 55 and 65 and the second connection plates 56 and 66 are rotated in the direction away from each other with the hinge pins 53c and 63c of the rotation connecting means 53 and 63 as the center, The wire rope rings 51 and 61 and the insulator rings 52a and 62a and 52b and 62b are connected to the wire rope loop support pins 55b and 65b and the insulator ring support pins 55d and 65d, The first connecting plates 55 and 65 and the second connecting plates 56 and 66 are placed on the hinged orbit of the rotating connecting means 53 and 63 as shown in Figure 5 (b) The wire rope loop support pins 55b and 65b and the insulator ring support pins 55d and 65d and 55f and 65f are connected to the wire rope rings 51 and 61 And the insulator rings 51 and 61, and as shown in Fig. 5 the wire rope loop supporting pins 55b and 65b and the insulator ring supporting rods 56 and 66 are brought into contact with each other when the first connecting plates 55 and 65 and the second connecting rods 56 and 66 are brought into contact with each other, The pins 55d, 65d, 55f and 65f pass through the wire rope rings 51 and 61 and the insulator rings 51 and 61 and then the wire rope loop supporting pin grooves 56b and 66b and the insulator ring supporting pin grooves 56d , 66d, 56f, 66f.

At this time, the wire rope rings 51 and 61 and the insulator rings 52a, 52b, 62a and 62b are inserted into the wire rope loop inserting grooves 55a, 65a, 56a and 66a and the insulator ring inserting grooves 55c, 65c, 66c.

In this state, when fastened to the bolt fastening holes 54b, 64b of the second connection plates 56, 66 through the bolt through holes 54a, 64a of the first connection plates 55, 65, the wire rope rings 51 61a and insulator rings 52a, 62a, 52b and 62b are inserted into wire rope loop insertion grooves 55a, 65a, 56a and 66a and insulator ring insertion grooves 55c, 65c, 56c and 66c, L12, L21 and L22 of the wire ropes 30 and 40 and the left and right working transmission cables L1 and L2 are supported by the support pins 55d, 65d, 55f and 65f, 50, 60) and insulators (i11, i12, i21, i22).

As described above, according to the corridor body fixing device for a working transmission line according to the present embodiment, the left and right working transmission cables L1 and L2 made up of the small conductors L11, L12, L21 and L22 are connected to each other by bolts The risk of a safety accident can be greatly reduced.

Particularly, since the processed transmission cable is a complicated operation in which the work is performed at the upper end of the steel tower, the accident of people can be greatly reduced.

Hereinafter, the process of relaxing the tension of the working transmission cables L1 and L2 made up of the small conductors L11, L12, L21 and L22 by the corridor fixing device for the working transmission line according to the present embodiment will be described.

The working transmission cables L1 and L2 made up of the small conductors L11, L12, L21 and L22 are expanded or contracted according to the temperature. When they are excessively stretched, they sag downward. When they are excessively contracted, So that the supporting state of the working transmission cables L1 and L2 with respect to the power transmission towers T may become unstable.

To cope with this, in this embodiment, the winding drum 20, the left wire rope 30, the right wire rope 40, the left and right connecting means 50 and 60, the driving motor 70 and the transmission means 80, The sensor 90 and the control unit 100 can compensate for the expansion and contraction of the working transmission cables L1 and L2.

10 (a) shows a state in which the working transmission cables L1 and L2 do not expand and contract beyond the normal range in the middle temperature range as in spring and autumn, and FIG. 10 (b) FIG. 10 (c) shows a state in which the deflection of the working transmission cables L1 and L2 is compensated by pulling the working transmission cables L1 and L2 extended beyond the normal range when the range is in the range The processed transmission cables L1 and L2 contracted beyond the normal range are pushed out to compensate the tension of the working transmission cables L1 and L2.

In the case where the temperature is in the middle temperature range as in spring and autumn, the degree of winding of the left and right wire ropes 30 and 40 with respect to the winding drum 20 becomes intermediate as shown in FIG. 10 (a) The left and right wire ropes 30 and 40 are kept in a state of having a winding allowance and a winding allowance for the winding drum 20, respectively.

When the small conductors L11, L12, L21, and L22 constituting the transmission power transmission cables L1 and L2 are in a temperature range high enough to be stretched as in the summer, the temperature sensor 90 senses this, The controller 100 outputs a forward rotation (counterclockwise rotation) command in accordance with the temperature detection signal received from the temperature sensor 90. When the drive motor 70 is in the forward direction Counterclockwise).

When the drive motor 70 rotates counterclockwise when viewed from the front, the first worm 81 rotating integrally with the motor shaft 72 rotates counterclockwise when viewed from the front, and the first worm 81 The first worm wheel 82 engaged with the first worm wheel 81 rotates in a clockwise direction when viewed from the plane and the second worm 83 rotating integrally with the first worm wheel 82 rotates clockwise And the second worm wheel 84 engaged with the second worm 83 rotates counterclockwise when viewed from the front.

The second worm wheel 84 is fixedly coupled to the rear drum shaft 23b of the winding drum 20 so that the winding drum 20 rotates in the counterclockwise direction and the left worm wheel 84 of the winding drum 20 rotates counterclockwise, The left wire rope 30 wound rightward on the winding portion 21 and drawn to the left from the lower side of the winding portion 21 and the winding wire 22 wound on the winding portion 22 are wound on the upper side of the winding portion 21 The right wire rope 40 drawn to the right side is wound on the winding portions 21 and 22, respectively.

Left and right wire ropes 30 and 40 are wound on the winding portions 21 and 22 so that the left and right wire ropes 30 and 40 are connected to the left and right connecting means 50 and 60 and the insulators i11, L12, L21, and L22 constituting the working transmission cables L1 and L2 connected to each other through the cables i1 and i22 are pulled.

The small conductors L11, L12, L21 and L22 constituting the elongated working transmission cables L1 and L2 are stably supported on the arm A of the power transmission towers T without falling down .

On the other hand, when the small conductors L11, L12, L21 and L22 constituting the working transmission cables L1 and L2 are in a temperature range low enough to shrink, as in the winter, the temperature sensor 90 senses this, The controller 100 outputs a reverse rotation (clockwise rotation) command in response to the temperature sensing signal of the temperature sensor 90. When the driving motor 70 is in the reverse direction Direction).

The first worm 81 rotating integrally with the motor shaft 72 rotates in a clockwise direction when viewed from the front and the first worm 81 The second worm 83 rotating integrally with the first worm wheel 82 rotates in the counterclockwise direction when viewed from the plane. The first worm wheel 82 rotates counterclockwise when viewed from above, And the second worm wheel 84 engaged with the second worm 83 rotates clockwise when viewed from the front.

The second worm wheel 84 is fixedly coupled to the rear side drum shaft 23b of the winding drum 20 so that the winding drum 20 rotates in the clockwise direction and the left winding portion of the winding drum 20 21 and wound on the left side of the wire rope 30 and the winding portion 22 that are drawn out from the lower side of the winding portion 21 to the left side and wound on the right side of the winding portion 21 from the upper side The right wire rope 40 pulled out by the winding portions 21 and 22 is released.

As the left and right wire ropes 30 and 40 are loosened to the winding sections 21 and 22, the left and right wire ropes 30 and 40 are connected to the left and right connecting means 50 and 60 and the insulators i11, i12 and i21 L12, L21, and L22 constituting the working transmission cables L1 and L2 connected to each other through the power lines i1 and i22.

As a result, the small conductors L11, L12, L21 and L22 constituting the contracted transmission power transmission cables L1 and L2 are sagged by their own weights and the tension is relaxed so that the small conductors L1 and L2, (L11, L12, L21, L22) are stably supported on the arm (A) of the transmission tower (T)
