BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-

The present invention relates to a connection insulator structure of an extra high voltage distribution machined wire in the field of distribution technology, and more particularly, to a connecting insulator structure of a high voltage distribution distribution wire which can be installed relatively easily and stably on the upper end of the insulator main body, The present invention also relates to a connection insulator structure of an extra high voltage power distribution machining wire for adjusting the tension of a working wire while allowing a replacement work to be carried out easily even when the insulator main body is damaged.

Generally, electric power generated by a power plant is supplied to a demanding place of industry or each household through a substation through a high-voltage transmission / distribution line. A transmission / distribution line for supplying electricity from a power plant to a substation is made up of a steel tower, Or shape depending on voltage or terrain.

The steel tower usually supports two wires of three phases, ie six wires, and the distance between the towers is about 20 ~ 30m. The electric wires installed on the tower are determined by the electric equipment technology from the ground.

However, when a railway crosses a river or a deep valley, the tension of the wire increases as the span becomes longer. Therefore, a steel tower with a stronger structure is required.

In this case, the transmission / distribution line is normally installed at a high position, so that it can be managed relatively safely. However, when a crane, an excavator, a ladder or the like is used, a direct impact may be applied to the transmission / distribution line due to carelessness.

When the strong shock is applied to the transmission and distribution line through the insulation insulator, the insulation between the insulation insulator and the transmission and distribution line is broken and the connection is released or the transmission and distribution line is crashed and the transmission and distribution line is severely broken Electric shock accidents may occur.

As a conventional technique which partially improves such a problem, Korean Patent Registration No. 10-1365654 (Feb. 24, 2014) discloses a connection plug of an extra-high voltage distribution processing wire.

However, there is a problem that it is difficult to control the tensile force of the working wire because the connection insulator of such conventional high-voltage power distribution working wire is difficult to control.

[

The insulator main body 10 is formed of an insulative material such as polymer or ceramic in the shape of a sack and is mounted on the fixing plate 11. The fixing plate 11 is fastened to the main body P by the fastening bolt 12. [ So that the machined wire L can be held mechanically and firmly by being bound on the coarse iron S.

The first cushioning member 20 includes a disk-shaped seating portion 21a and a connecting arm 21b inclined to both sides from the seating portion 21a and connected to each other so as to face each other, Shaped extension plate 21c which is held in a state of being in a state of being in a state of being in a state of being in a state of being.

A metal reinforcing piece 14 for fastening the fixing bolt 13 is embedded in the center portion of the insulator body 10 at the seating portion 21a of the first cushioning member 20, The vibration damping pad 15 and the anti-loose washer 16 are interposed between the first cushioning members 20.

The second cushioning member 30 can be fixed on the extension plate 21c of the first cushioning member 20 by fastening bolts 31. The cover 32b is formed on the cylindrical casing 32a, Is fixed by a fastening bolt (33), and a moving rod (35) which elastically moves up and down by a spring (34) and the spring (34).

Each wire fixing member 40 is provided on the upper side of the moving rod 35 constituting the second buffer member 30 so that the working wire L can be mechanically gripped and held firmly.

Meanwhile, when the working wire (L) is relatively weakly shaken due to the deterioration of the weather such as a strong wind or a typhoon, the fixed wire The load is transmitted to the second buffer member 30 through the second elastic member 42, but the moving rod 35 moves up and down by the elastic force of the spring 34 to perform the buffering function.

A load acts on the first cushioning member 20 together with the second cushioning member 30. When a strong load is applied to the working cable L, a load acts on the first cushioning member 20 together with the second cushioning member 30. However, 21b are able to buffer the load by receiving their own elastic force like the leaf spring.

Since the first buffer member 20 and the insulator body 10 are bound to each other via the dust-proof pad 15, the first buffer member 20 and the second buffer member 20, 2 cushioning member 30 as well as the load applied to the insulator main body 10 can be reduced.

In the present invention, the configuration of the tension adjusting unit 100 for adjusting the tension of the working wire L is further implemented as shown in FIGS. 5 to 6, including the above configuration.

The tension adjusting unit 100 adjusts the tension of the working wire L so that the tension applied to the second cushioning member 30 can be adjusted by appropriately adjusting the tensile force, So that the buffer can be smoothly performed.

Accordingly, the tension adjuster 100 smoothly buffers the second buffer member 30 by appropriately adjusting the tension of the working wire L between the second buffer members 30 .

The tension adjusting unit 100 includes a support plate 110 disposed below the working cable L so as to be positioned between the second buffer members 30 and a support plate 110 extending from the connection arm 21b to the support plate 110. [ A clamp 130 connected to the working wire L and a clamp 130 for supporting the clamp 130 from the supporting plate 110 while controlling the tension of the working wire L And a tension adjusting means (140).

Both ends of the support plate 110 extend in the longitudinal direction of the working wire L.

The supporting means 120 includes a lower binding member 121 having a lower portion fixed to the connecting arm 21b so as to be disposed on both sides of the fixing bolt 13 and having an upper portion opened and a thread formed on an inner peripheral surface thereof, And a thread is formed on the inner circumferential surface of the support bar 122 to form a thread on the upper outer circumferential surface of the support bar 122. The support bar 122 is screwed to the lower binding member 121, And an upper binding member 123 screwed to an upper portion of the supporting bar 122 to bind the supporting plate 110 to the supporting bar 122.

The supporting bar 122 includes a lower bar 124 screwed to the lower binding member 121 and a lower bar 124 extending upward from the upper portion of the lower bar 124 and screwed to the upper binding member 123, And an upper bar 125 formed on the upper side.

The lower bar 124 is formed to have a larger diameter than the upper bar 125 and has a step 124a for supporting the support plate 110 thereon.

Accordingly, the support means 120 can be smoothly attached to and detached from the connection arm 21b, and the support plate 110 can be stably supported.

The clamp 130 connects the first and second side plates 132 and 133 disposed on both sides of the working wire L and the lower ends of the first and second side plates 132 and 133 and supports the working wire L And a detachment preventing means 135 for preventing the detachment of the working wire L from the securing frame 131.

It is preferable that the connection plate 134 has a curved shape in which both ends are integrally connected to the lower portions of the first and second side plates 132 and 133 and the lower ends thereof protrude downward.

Accordingly, the fastening frame 131 has a 'U' shape in which the first and second side plates 132 and 133 and the connecting plate 134 are integrally connected and the machining wire L is seated inward.

One end of the release preventing means 135 is located inside the fastening frame 131 and the other end is passed through the first side plate 132 of the first and second side plates 132 and 133, An anti-tamper bar 136 which is movably coupled to the first side plate 132 in the opposite end directions, an engaging member 137 which is engaged with one end of the anti- And a spring 138 coupled to the outside of the bar 136 to prevent the bar 138 from being damaged.

The prevention bar 136 may be formed of a bolt having a head at the other end and a thread formed on the outer circumference.

The coupling member 137 may be formed of a nut having a thread formed on an inner peripheral surface thereof.

The spring 138 urges the engaging member 137 to the second side plate 133 to close the upper portion of the first and second side plates 132 and 133, And the upper end of the fastening frame 131 is opened while the one end of the preventing bar 136 is contracted in the outward direction.

That is, when the upper portion of the fastening frame 131 is opened, the release preventing means 135 pulls the other end portion of the preventive bar 136 outward so that the engaging member 137 engages with the second side plate 133 So that the spring 138 is compressed and opened.

Thus, the machining wire (L) can be received in the fastening frame (131) or the machining wire (L) can be drawn out from the fastening frame (131).

On the other hand, when the upper portion of the fastening frame 131 is closed, the anti-departure means 135 may prevent the prevention bar 136 from being lifted by the elastic force of the spring 138 due to release of the pressure to the prevention bar 136, Is returned to its original state and closed.

Accordingly, it is possible to prevent the machining wire (L) received in the inside of the fastening frame (131) from coming off.

The tension adjusting means 130 includes a control bar 141 which supports the clamp 130 from the support plate 110 and forms a screw thread on the outer circumferential surface thereof and a screw thread formed on the inner circumferential surface thereof to be screwed to the control bar 141 And a control member 142 rotatably connected to the support plate 110 to fix the control bar 141 to the support plate 110.

The adjusting member 142 may be rotatably connected to the support plate 110 by a bearing or the like.

The upper portion of the control bar 141 is connected to the fastening frame 131 and the lower portion of the control bar 141 extends downward to be passed through the control member 142 while being screwed to the control member 142.

The control member 142 is rotated and lifted by the control bar 141 so that the working wire L together with the clamp 130 is pulled up or pulled back to adjust the tension.

For example, when the working wire L is laid on the basis of a horizontal state, the adjusting member 142 is tightened and rotated to move the adjusting bar 141 up and down, So that the tension can be adjusted.

On the contrary, when the adjusting member 142 is loosened and the adjusting bar 141 is lowered, the working wire L is kept substantially horizontal and the tension is controlled.

The tension adjusting means 140 may further include a release preventing member 143 coupled to the lower portion of the control bar 141 to be positioned below the control member 142.

The release preventing member 143 can be understood as a nut having a thread on the inner peripheral surface.

The control bar 141 includes an upper control bar 144 whose upper portion is connected to the coupling frame 131 and is screwed to the control member 142 and a lower control bar 144 extending downward from the lower portion of the upper control bar 144 And a lower control bar 145 formed with threads on the outer circumferential surface thereof and screwed to the release preventing member 143.

The upper adjustment bar 144 has an outer diameter larger than the outer diameter of the lower adjustment bar 145 and has a lift preventing jaw 144a for preventing the lift preventing member 143 from moving up and down.

Accordingly, when the release preventing member 143 is screwed into the lower control bar 145, the separation preventing member 143 can be prevented from moving up and down to the upper control bar 144, It is possible to prevent the control bar 141 from coming off.

Therefore, the tension adjuster 100 can smoothly buffer the second buffer member 30 by appropriately adjusting the tension of the working wire L between the second buffer members 30 .
