Description

Linker apparatus for controlling tension of distribution line

The present invention relates to an insulator ringer device for a distribution line capable of controlling tension among distribution field technologies, and more specifically, to a left and right overhead distribution line while allowing tension and deflection control for the left and right overhead distribution lines to be simultaneously performed. When the tension applied to the power distribution line is different, the insulator ringer device of the distribution line that can adjust the tension can be adjusted so that the tension and sag of the left and right overhead distribution lines can be more effectively controlled by varying the adjustment width for the left and right overhead distribution lines. it's about

In general, overhead distribution lines have a pole installed at a certain distance along the roadside, a pair of left and right arm bars fixed to the upper part of the pole, an insulator with one end fixed to a pair of left and right arm bars, and a free end of the insulator. It consists of fixed left and right overhead distribution lines, and a jump line connecting the left and right overhead distribution lines.

Such overhead distribution lines are stretched according to changes in temperature, resulting in a change in tension. That is, in summer, it is stretched due to high temperature and sag occurs, and in winter, it is contracted due to low temperature, increasing tension.

Recently, due to environmental pollution, the daily temperature difference between the minimum and maximum temperature is gradually increasing, and abnormal high temperature phenomenon in summer and abnormal low temperature phenomenon in winter are continuing. the current situation.

This change in tension of the overhead distribution line causes an increase in stress and sag on the overhead distribution line, and it affects the stable distribution of the overhead distribution line. there is

The tension control device for overhead distribution lines according to the prior art is to relieve tension by pushing left and right overhead distribution lines by linear actuators, etc. or to relieve sagging by pulling. The jump wire that is supported and connects the left and right overhead distribution lines through the left and right connection ports is supported in an insulated state against the steel through the line post insulator. The distance between the left and right connection ports connecting the jump line becomes greater, and the radius of curvature of the jump line becomes larger. As the distance between them gets closer, the radius of curvature of the jump line becomes smaller.

At this time, when the tension of the left and right overhead distribution lines is relieved, the jump line is tensed and the radius of curvature is increased. If it is not installed with sufficient length, there is a problem that poor contact occurs at the left and right connection ports.

In addition, if the sagging is relieved by pulling the left and right overhead distribution lines, the radius of curvature becomes smaller as the jump line is farther away. There is a problem in that the portion of is bent higher than the support point by the line post insulator, that is, it is bent like a bow, and the support state is poor.

As a prior art for tension control of a conventional overhead distribution line, Korean Patent Laid-Open No. 10-2014-0100175 "A chain-type tension control mechanism capable of adjusting the length of an overhead transmission/distribution line" (hereinafter referred to as 'prior art 1') is Disclosed is a technology that enables the length of overhead transmission and distribution lines to be adjusted without damage to the wires by using a chain-type tension control mechanism instead of a ball shackle that connects light arms and suspension insulators without dismantling the connected dead-end clamps.

In addition, as a prior art for tension control of overhead distribution lines, Republic of Korea Patent No. 10-1002422 "Insulator-fixed wrought iron for tension control of overhead distribution lines" (hereinafter referred to as 'Prior Art 2') has one end of the overhead distribution line fixed An insulator support part on which the insulator is supported, a spring shock absorber for buffering the insulator support part, a pressure sensor for detecting pressure according to the tension applied to the overhead power distribution line, a screw for raising and lowering the insulator support part, and a screw driving device, the pressure Disclosed is a technology for controlling the tension of an overhead power distribution line while the insulator support part ascends and descends by driving a screw drive device according to the pressure sensed by the detection sensor.

In addition, as a prior art for tension control of conventional overhead distribution lines, Republic of Korea Patent No. 10-1466138 "Tension relieving device for transmission towers of overhead wires for transmission" (hereinafter referred to as 'Prior Art 3') is a central A right-hand thread and a left-hand threaded female thread are formed on the left and right sides of the rotation shaft of the driving motor, respectively, and the left and right driving screws, each of which are right-handed and left-handed, are screwed to these female threaded parts, and are connected to the left and right driving screws. By connecting the left and right overhead wires for transmission through an insulator, the tension of the overhead wires for transmission can be simultaneously relieved by using the central drive motor and both sides drive motor without using high-pressure gas, so the installation cost of the transmission tower can be minimized, and components for tension relief such as the central first drive motor, left and right second drive motors, first drive screw, left and right second drive screw, connection means, and tension sensor are included in the protective cover The structure is simple as it is arranged in an in-line structure inside of the transmission tower, and the installation of the tension relief device is completed only by fixing the protection cover to the arm of the transmission tower. Therefore, it is not polluted by snow, rain, dust, etc., so that it does not malfunction or become inoperable. , By connecting the insulator and the overhead wire for transmission through the tension sensing means and the connecting rod to the left and right second drive screws moved left and right by the left and right second drive motors, the operating force for relieving the tension of the overhead wire for transmission is applied. Disclosed is a technology that allows for a smooth tension relief operation by doubling.

However, the prior arts do not solve the problems of the prior art as described above, although they relieve the tension or deflection of the left and right overhead distribution lines like the prior art.

In addition, as a prior art to solve the problems of the prior art, Republic of Korea Patent No. 10-1884290 "Insulator-fixed arm iron for tension control of a processing distribution line" (hereinafter referred to as 'prior art 4') is between the left and right arm irons. Through left and right suspension insulators to left and right operating screws having male threads engaged with left and right female threads formed by different spiral directions respectively on the left and right half of the inner peripheral surface of the hollow motor shaft of the drive motor fixed to the By connecting the left and right overhead distribution lines, the tension and sag of the left and right overhead distribution lines can be relieved, and the line post insulator can be raised and lowered by interlocking the tension and deflection relief operation to support the jump line in a more stable state. Disclosed is a technology that is positioned on the same vertical plane as the left and right overhead distribution lines, and the middle part is supported by the line post insulator to keep the jump line more stable.

However, it is possible to adjust the tension according to the change in the tension of the overhead power distribution line, and since the adjustable width to maintain the overhead power distribution line more stably is limited to the distance from the middle to the left end of the hollow motor shaft and the distance from the middle to the right end of the drive motor Since it is less than half of the total length, the adjustment width is small, so there is a problem in that tension control and sag relief of overhead distribution lines are not sufficiently performed.

Since such a control means can be variously configured by adopting a conventional control method, a detailed description thereof will be omitted.

Hereinafter, the operation of the insulator ringer device of the distribution line capable of adjusting the tension according to the present invention will be described.

As shown in FIG. 4 when the insulator ringer device for a distribution line capable of adjusting tension according to the present invention is initially installed, the slider 710, the first driving motor 730, and the first pinion 720 are the guide 200. It is located in the middle of the, the left moving rack 300 protrudes from the left arm convex 21 to the left by about half, and the right moving rack 400 is installed in a state in which it protrudes about half to the right from the right arm convex 22.

In this state, the control means sets the pressure detected by the left and right pressure sensors 500 and 600 as a reference value, and later, when the pressure value detected by the left and right pressure sensors 500 and 600 is greater than the reference value, the tension is increased. It is determined that it is increased, and in the opposite case, it is determined that the tension is decreased, that is, sagging has occurred, so that the first driving means 700 and the second driving means 800 can be controlled.

In this state, the tension applied to the left and right overhead distribution lines 41 and 42 is installed between the left and right insulator connectors 330 and 430 of the left moving rack 300 and the left and right insulator connectors 37 and 38. , is detected by the right pressure sensors 500 and 600, when the tension values detected by the left and right pressure sensors 500 and 600 are the same, the second driving means 800 is not operated by the control means, and the second driving means 800 is not operated. Only one driving means 700 may be controlled to be operated.

When the temperature is low, such as in winter, the left and right overhead distribution lines 41 and 42 contract and the tension increases, and when the tension value sensed by the left and right pressure sensors 500 and 600 increases, the first driving motor The 730 is activated so that the first driving motor shaft 731 and the first pinion 720 coupled thereto rotate counterclockwise when viewed from above, and the rack portions 340 and 440 engaged with the first pinion 720 . ), the left moving rack 300 moves to the left and the right moving rack 400 moves to the right by the gear action.

When the left moving rack 300 moves to the left and the right moving rack 400 moves to the right, the left insulator connector 37 and the left insulator 31 are connected to the left insulator connection part 330 of the left moving rack 300. and the left processing distribution line 41 connected through the left connector 51 is pushed to the left, and the right insulator connector 38 and the right insulator 32 and the right insulator connector 430 of the right moving rack 400 are connected to the right The right overhead distribution line 42 connected through the connection port 52 is pushed to the right, so that the tension of the left and right overhead distribution lines 41 and 42 is relieved (refer to FIG. 5).

Conversely, when the temperature is high, such as in summer, the left and right overhead power distribution lines 41 and 42 are stretched to cause sagging, and when the tension values detected by the left and right pressure sensors 500 and 600 decrease, the first drive The motor 730 is operated so that the first driving motor shaft 731 and the first pinion 720 coupled thereto rotate clockwise when viewed from above, and the rack parts 340 and 440 engaged with the first pinion 720 . ), the left moving rack 300 moves to the right, and the right moving rack 400 moves to the left due to the gear action.

When the left moving rack 300 moves to the left and the right moving rack 400 moves to the right, the left insulator connector 37 and the left insulator 31 are connected to the left insulator connection part 330 of the left moving rack 300. and the left processing distribution line 41 connected through the left connection port 51 is pushed to the right, and the right insulator connector 38 and the right insulator 32 to the right insulator connection part 430 of the right moving rack 400 and the right overhead distribution line 42 connected through the right connection port 52 is pulled to the left, so that the sagging of the left and right overhead distribution lines 41 and 42 is alleviated (see FIG. 6 ).

Here, the left moving rack 300 can pass through the left rectangular hole 110 of the left arm 21 as well as the right rectangular hole 120 of the right arm 22, and the right side of the right moving rack 400 Since the right square hole 120 of the armrest 22 as well as the left square hole 110 of the left armrest 21 can pass through, the left and right movement distance is greater than the interval between the left and right armholes 21 and 22. As it becomes longer, the adjustment width for tension and sag control becomes large, and the tension and sag control of the left and right overhead distribution lines 41 and 42 are more fully performed, so that the left and right overhead distribution wires 41 and 42 can be maintained more stably. there will be

On the other hand, if the amount of sunlight and the influence of wind on the left and right overhead distribution lines 41 and 42 are different depending on the location where the overhead distribution line is installed, different tension and deflection may occur in the left and right overhead distribution lines 41 and 42. may be

In this case, despite the difference in tension and deflection that occur substantially, when the tension and deflection are adjusted only by the first driving means 700 as described above, the tension and deflection for the left and right overhead distribution lines 41 and 42 are different. Adjustment may not be done properly.

Therefore, in this case, the slider 710, the first pinion 720, the first driving motor 730, and the left and right moving rack 300 constituting the first driving unit 700 by the second driving unit 800 are , 400), of course, by moving the second pinion 820 and the second driving motor 830 of the second driving means 800 to the left or right, the tension and deflection of the left and right overhead distribution lines 41 and 42 Adjustments can be made to be appropriate.

That is, when the tension of the left overhead power distribution line 41 sensed by the left pressure sensor 500 is large and the tension of the right overhead power distribution line 42 sensed by the right pressure sensor 600 is small, the second drive motor ( 830 is activated, so that the second driving motor shaft 831 and the second pinion 820 coupled thereto rotate counterclockwise when viewed from the front.

When the second pinion 820 rotates in the counterclockwise direction, the second pinion 820 and the second driving motor 830 are driven by the gear action of the rack portion 820 of the second pinion 820 and the fixed rack 810. It moves to the left, and since the second drive motor 830 is coupled to the slider 710, the slider 710, the first drive motor 730, and the first pinion 720 of the first drive means 700 and Left and right moving racks 300 and 400 are moved to the left.

In this state, as described above, when the left moving rack 300 is moved to the left by the first driving means 700 and the right moving rack 400 is moved to the right to adjust the tension, the left processing distribution line 41 ), the tension control width for the right overhead distribution line 42 is larger than the tension control width for the left and right overhead distribution lines 41 and 42 are properly adjusted.

Conversely, when the tension of the right overhead distribution line 42 is large and the tension of the left overhead distribution line 41 is small, the second driving motor 830 is operated to operate the second driving motor shaft 831 and the second coupled thereto. The pinion 820 rotates clockwise when viewed from the front.

When the second pinion 820 rotates in the clockwise direction, the second pinion 820 and the second driving motor 830 move to the right due to the gear action of the second pinion 820 and the rack part 820 of the fixed rack 810. and the second drive motor 830 is coupled to the slider 710, so the slider 710, the first drive motor 730, the first pinion 720 and the left side of the first drive means 700 , the right moving rack (300, 400) is moved to the right.

In this state, when the left moving rack 300 is moved to the right by the first driving means 700 as described above in this state, and the right moving rack 400 is moved to the left to adjust the tension,

The tension adjustment width for the right overhead distribution line 42 is greater than the tension adjustment width for the left overhead distribution line 41, so that the tension adjustment for the left and right overhead distribution lines 41 and 42 is appropriately performed.

In addition, the control means is in the summer when sagging occurs in the left and right overhead power distribution lines 41 and 42, when the pressure detected by the left pressure sensor 500 and the right pressure sensor 600 is smaller than the reference value and different from each other, the left overhead power distribution line 41 ) and the right processing distribution line 42 are determined to have different sags, and the second driving means 800 is controlled to move the first driving means 700 and the left and right moving racks 300 and 400 to the side with a small sag. It can be moved so that the sag of the left and right overhead distribution lines 41 and 42 can be adjusted appropriately.

That is, when the tension of the left overhead power distribution line 41 sensed by the left pressure sensor 500 is large and the tension of the right overhead power distribution line 42 sensed by the right pressure sensor 600 is small, the left overhead distribution line 41 ) is greater than the deflection of the right overhead distribution line 42, the first driving means 700 and the left and right moving racks 300 and 400 by the second driving means 800 as in the above-described tension adjustment. is moved to the right so that the sag control width for the left overhead distribution line 41 is larger than the sag control width for the right overhead distribution line 42, so that the sag adjustment of the left and right overhead distribution lines 41 and 42 can be properly performed. There is (see Fig. 7).

Conversely, when the tension of the right overhead power distribution line 42 sensed by the right pressure sensor 600 is high, the pressure of the left overhead power distribution line 41 sensed by the left pressure sensor 500 is large, and by the right pressure sensor 600 When the sensed pressure is small, the first driving means 700 and the left and right moving racks 300 and 400 are moved to the left by the second driving means 800, and the main and right processing distribution lines 41 and 42 are By making the sag control width for the left and right overhead distribution lines 41 and 42 larger than the sag control width for the left overhead power distribution line 41, the sag adjustment of the left and right overhead power distribution lines 41 and 42 can be properly performed (see FIG. 8).
