Abstract

More particularly, the present invention relates to a lead-in method for guiding an electric wire through which a high-voltage current flows, The present invention relates to a drawing-in main lever for an extra-high pressure machining distribution line so as to maintain the state of the first and second insulator members coupled to the rotating body without being released to the outside.

Description

[0001] The present invention relates to an extreme high tension support type electric power distribution line,

[0001] The present invention relates to a lead-in main conductor for a special high-pressure machining distribution line in the field of power distribution technology, and more particularly to a lead-in main conductor for guiding an electric wire through which a high-voltage current flows, And the first and second insulator members are connected to the rotating body without releasing the first and second insulator members to the outside in accordance with the unclamping rotation of the first and second insulator members.

Generally, in order to increase the efficiency of electricity transmission, the power plant can highly transform the transmission voltage to a high voltage of 154 KV or more according to one embodiment and transmit it to the destination.

However, since such high-voltage electricity can not be used in real life, it is decompressed through a pillar-type transformer or the like, and transformed to be used in a home or a factory.

However, in a place where a relatively high voltage is used compared to a home, such as a large-scale industrial complex, a factory, etc., a self-substation can be operated in place of a pillar transformer.

The power plant uses an extra-high voltage input lead to guide the high-voltage current through the transmission line while increasing the transmission voltage.

Extra-high pressure inlet is equipped with insulator on wand iron to flow high pressure current safely, and high-voltage electric current is flowed by fixing high-voltage wire on insulator.

Extra-high pressure inlet The insulator is a material with a very high resistance to flow the high-voltage current safely.

The high voltage induction furnace has several insulators with high resistance to increase the insulation rate and prevent the current from flowing to the ground.

However, if the insulator installed in the high pressure inlet is damaged, there is a problem in the insulation rate and current may flow to the ground, so that quick replacement of the broken insulator is given priority.

As a conventional technique which partially alleviates such a problem, Korean Patent Registration No. 10-0809098 (Mar. 4, 2008) discloses a special high voltage induction furnace supported by a distribution line.

However, there is a problem that the first and second insulator members can be released to the outside according to the release rotation of the first and second bolts when the rotating body for replacing the insulator is supported by the conventional distribution line .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. And should not be construed as limited to the embodiments described herein.

Since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein.

It should be understood that the embodiments according to the concept of the present invention are not limited to the particular mode of disclosure but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The present invention utilizes the same as that of the later-described Japanese Patent Application No. 0809098, and therefore all of the features of the device configuration described below can be understood as those described in Patent Registration No. 0809098.

However, according to the present invention, the 'high-voltage induction furnace with a distribution line support type' is replaced with 'a high-pressure processing induction furnace lead-in value' among the configurations disclosed in the above-mentioned Japanese Patent No. 0809098, The first and second insulator members are not detached to the outside, and a state in which the first and second insulator members are coupled to the rotating body is maintained.

Therefore, the device structure, features and operation relationship described below will be referred to as the contents of the above-mentioned Japanese Patent Application No. 0809098, and the structure related to the main features of the present invention will be described in detail at the rear end.

Referring to Figs. 1 and 2, a drawing-in master (hereinafter referred to as " drawing master ") of an extra-high pressure machining distribution line according to the present invention further includes an insulator for supporting the distribution line.

The second insulator 120, which is an extra insulator, is located on the opposite side of the first insulator 110 supporting the distribution line.

When a broken insulator is generated in the first insulator 110 supporting the distribution line, the first insulator 110 and the second insulator 120 are rotated to rotate the first insulator 110 and the second insulator 120, After the position of the second insulator 120 is changed, the second insulator 120, which is an extra insulator, is used to support the distribution line.

It is safe to use the first insulator 110 for insulators supporting the distribution line.

When the insulator supporting the distribution line is the first insulator 110, the distribution line is fixed to the clasp 140 and the first insulator 110 and the second insulator 120 are fixed to the rotating body 130 ) To change the position of the insulator to replace the damaged insulator, and fix the power line fixed to the clasp 140 to the second insulator 120 that has been moved.

The first insulator 110 and the second insulator 120 are rotated by the rotating body 130 to change the positions of the insulators so that the insulators are exchanged with each other.

The first insulator 110 or the second insulator 120 is provided with a thread on a shaft for fixing the insulator so that the thread of the insulator and the thread of the rotating body 130 are coupled to each other to be fixed to the rotating body 130.

The latch (140) is located in the solid iron (160) and serves to temporarily fix the distribution line when the insulator is replaced.

The coarse iron 160 is installed so as to protrude in the horizontal direction at the upper end of the electric pole.

When replacing the insulators, there should be no current in the distribution line. Current leakage may occur in the distribution line when an insulator is damaged.

Find the place where the current leakage occurred and replace the broken insulator.

The first insulator 110 or the second insulator 120 may increase the number of insulators in the first insulator 110 or the second insulator 120 so as to allow a current of a higher voltage than that of the high voltage supported by the insulator to pass therethrough So that a high-voltage current can flow.

At the top of the insulator is a loop that supports the distribution line.

After fixing the distribution line in the loop, after the replacement of the insulator is completed, take measures so that high-voltage current can flow through the distribution line.

The bare iron supported by the lifting base is composed of the cap 150 and the bare iron 160.

Between the cap 150 and the solid iron 160, the rotating body 130 is positioned to rotate the rotating body 130.

When the rotating body 130 rotates, the first insulator 110 and the second insulator 120 fixed to the rotating body 130 rotate, and the positions of the first insulator 110 and the second insulator 120 are changed.

The cap 150 is fastened to the swivel base 170 of the wrought iron 160 by the bolts 180 to form a single wrought iron.

The rotating body 130 is coupled to the rotating shaft 170 of the solid iron 160 and the bolts 180 are coupled to the rotating shaft 170 of the solid iron shaft 160 through the cap 150, So that one rotating body 130 can be easily rotated on the rotating table 170 while preventing the rotating body 130 from being separated from the rotating table 170.

The rotating body (130) has a screw groove to replace the insulator.

If it is necessary to flow a higher extra-high voltage current, replace it with a larger number of insulators.

The replaced insulator is fixed to the rotating body 130 so that the distribution line can be positioned.

The following is a description of the parts constitution of the withdrawal master cap except for the pole pole.

A first insulator 110, a second insulator 120, a swivel base 170, a cap 150 and a wrought iron 160 are coupled to the rotating body 130.

A first insulator 110 is coupled to the upper portion of the rotating body 130 and a second insulator 120 is coupled to the lower portion of the rotating body 130. A swivel 170 is coupled to the outside of the swivel 160, 170 are coupled to one side of the cap 150.

The first insulator 110 and the second insulator 120 coupled to the rotating body 130 are provided with a loop for fixing the distribution line.

When the distribution line is fixed to the loop, the pre-operation to blur the high voltage current is completed.

The rotating body 130 has a bearing structure capable of rotating at a position where the cap 150 and the bare iron 160 are coupled.

The rotating body 130 is configured as a plate bearing, and when the rotating body 130 is rotated by holding an insulator coupled to the rotating body 130, the rotating body 130 rotates.

The swivel (170) is positioned on the extension line of the wrought iron (160) and constitutes one wrought iron.

The swivel (170) is coupled with the wrought iron (160) so that it can maintain a fixed position even if an arbitrary force is applied.

The swivel arm 170 is integrally formed with the rotating body 170 and the first insulator 110. The swivel arm 170 is coupled to the rotating body 130, the cap 150, The first bolt 110a of the second insulator 120 and the second bolt 120a of the second insulator 120 pass through the rotating body 130 and are coupled to the rotating shaft 170 of the wrought iron 160, And the solid iron (160).

The first insulator 110 is provided with a first bolt 110a which passes through one side of the rotating body 130 and is press-fixed to the bare iron 160, thereby forming a first insulator member.

The second insulator 120 is provided with a second bolt 120a which passes through the other side of the rotating body 130 and is pressed and fixed to the coarse iron 160 to form a second insulator member.

The bolt 180 is coupled to the cap 150 so that the rotating body 130 is fixed to the rotating table 170 of the wrought iron 160 so that the first bolt 110a of the first insulator 110 And prevents the rotating body 130 from being separated to the outside when the second bolt 120a of the second insulator is separated.

The first insulator 110 or the second insulator 120 is provided with a ring for fixing the distribution line.

When the distribution line is located in the loop, an insulator is positioned between the loop and the wedge and acts as an insulator.

The insulator acting as an insulator varies in resistance value depending on the number of insulators.

In the present invention, the number of openings of the first insulator 110 and the second insulator 120 is determined to be the same, but the number of openings of the first insulator 110 and the second insulator 120 may be different.

If the number of insulators is different, the insulation rate of the insulator is changed and when the high voltage current needs to flow through the distribution line, the number of insulators can be replaced with a large insulator.

The latch 140 provided on the solid wire 160 temporarily fixes the distribution line so that the insulator replacement operation can be smoothly performed.

The latch 140 may also be located in the cap 150 instead of the solid iron 160. Since the latch 140 serves to temporarily fix the power distribution line, it may or may not be located in the cap 150 or the wrought iron 160 as needed.

If the latch 140 is not needed, the work device for replacing the distribution line should have a latch. Since the latch 140 helps smooth the insulator replacement work, the latch 140 can be provided to the lead-in bar as required.

The positions of the first insulator 110 and the second insulator 120 are changed by the rotation of the rotating body 130.

When the rotating body 130 rotates, the positions of the first insulator 110 and the second insulator 120 are changed.

The first insulator 110 or the second insulator 120 serves as an extra insulator as needed.

The first insulator 110 and the second insulator 120 have a loop to fix the distribution line. It is advantageous to use the second insulator 120 if the strength of the loop fixing the distribution line is large but it is more advantageous to use the first insulator 110 if the strength of the loop is insufficient to fix the distribution line.

In the case where the distribution line is located in both the first insulator 110 and the second insulator 120, it is possible to disperse a load due to the sagging of the distribution line due to the rotation of the rotation body 130.

When the load applied to the rough iron is dispersed, the rotating body 130 can rotate naturally according to the movement of the distribution line.

If the rotation of the rotating body 130 is excessive, a load applied to the rotating body 130 is increased to cause breakage between the rotating body 130 and the wrought iron. Therefore, It is preferable to avoid separating the first bolt 110a of the insulator 110 from the second bolt 120a of the second insulator 120. [

3, the first insulator 110 is pressed and fixed to the rotating table 170 by the first bolt 110a and the second insulator 120 is fixed to the rotating table 170 by the second bolt 120a. As shown in Fig.

The first bolt 110a of the first insulator 110 and the second bolt 120a of the second insulator 120 are pressed against the rotating table 170 and the first bolt 110a and the second bolt 120a, The rotating body 130 is rotatable on the rotating table 170. [

The cap 150 is fixed to the swivel base 170 by the bolts 180 to prevent the swivel 130 from deviating outward when it rotates on the swivel base.

The cap 150 may be pressed and fixed to the bare iron 160 by the bolts 180 in order to prevent the rotating body 130 from rotating on the rotating table 170.

That is to say, the rotation of the rotation body 130 prevents the rotation of the rotation body 130 on the rotation table 170 by pressing and fixing the cap 150 to the rotation body 130 by tightening the bolts 180 of the cap 150 do.

In the present invention, the first and second bolts 110a and 120a are not loosened and the first and second insulator members are not released to the outside according to the release rotation of the first and second bolts 110a and 120a, The configuration of the departure-avoiding portion 200 for maintaining the state of being coupled to the base 130 is further realized.

The departure prevention unit 200 prevents the first and second insulator members from being detached from the rotating body 130 when the first and second insulators 110 and 120 are changed in position.

This is because the loosening of the first and second bolts 110a and 120a is performed for the rotation of the rotating body 130 so that the first and second insulator members may be separated from each other.

Alternatively, the first and second insulator members may be released to the outside according to the incomplete coupling state of the first and second bolts 110a and 120a.

The separation preventing part 200 includes a coupling ring 210 coupled to the outside of the first and second bolts 110a and 120a, a supporting means 220 fixed to the rotating body 130, And a connection line 230 connecting to the connection terminal 220.

The coupling rings 210 are paired and coupled to the outside of the first and second bolts 110a and 120a, respectively.

The rotating body 130 is formed with a pair of coupling grooves 131 which are recessed inward from the outer circumferential surface so as to be positioned at one side of the first and second bolts 110a and 120a.

The coupling groove 131 extends inward from the outer circumferential surface of the rotating body 130 and faces the longitudinal direction of the first and second bolts 110a and 120a.

The support means 220 includes a support bolt 221 having a head portion 221a formed at one end portion thereof inserted into each coupling groove 131 and the other end protruding outwardly of the rotary body 130, A compression member 222 coupled to the outside of the support bolt 221 so as to be received in the coupling groove 131, a support ring 223 coupled to the outside of the rotation body 130 and through which the other end of the support bolt 221 passes And a nut 224 screwed to the support bolt 221 so as to be positioned on the outside of the compression member 222.

The supporting ring 223 is circular and is coupled to the outside of the rotating body 130 so as to cover the coupling groove 131.

6, a pair of through-holes 223a through which the other end of the support bolt 221 passes are formed in the support ring 223.

Preferably, the through hole 223a extends through the inner and outer peripheral surfaces, and extends from the center of the support ring 223 to one side. Accordingly, the through hole 223a has a 'U' shape in which one side is open when viewed from above.

This is for the purpose of facilitating the connection to the support bolt 221.

The support means 220 may further include a contact member 225 disposed between the support ring 223 and the rotating body 130.

The contact member 225 may be made of silicone or rubber so that movement or shaking of the support ring 223 does not occur in a state where the support ring 223 is disposed at a predetermined position.

The support bolts 221 are formed as a pair and are received in the coupling grooves 131 so as to be movable in the longitudinal direction.

The support bolt 221 is received in the coupling groove 131 and the other end passes through the support ring 223 and protrudes to the outside of the rotating body 130.

It can be understood that the support bolts 221 are disposed on the upper and lower sides of the rotating body 130 on the basis of a state where the first and second insulator members are disposed on the upper and lower sides of the rotating body 130.

The supporting means 220 may further include a reinforcing rib 226 coupled to the coupling groove 131 with both ends thereof opened.

It is preferable that the reinforcing ribs 226 are smoothly brought into contact with the pressing member 222 while unevenness (not shown) is formed on the inner peripheral surface.

It is preferable that the head portion 221a has a hexagonal shape and the coupling groove 131 has the same shape as the head portion 221a.

It is preferable that the reinforcing ribs 226 have the same inner and outer peripheries as those of the engaging grooves 131, and have a hexagonal shape.

This is to prevent the support bolt 221 from rotating together with the rotation of the nut 224.

The pressing member 222 is made of urethane or the like and is coupled to the outside of the supporting bolt 221 in a cylindrical shape opening up and down.

The compression member 222 is expanded or restored outwardly between the support ring 223 and the head portion 221a as the support bolt 141 is moved in the longitudinal direction when the nut 224 rotates.

The nut 224 is moved in the outward direction of the rotating body 130 by the rotation of the nut 224 so that the pressing member 222 is expanded outward between the supporting ring 223 and the head portion 221a, So that the means (220) is fixed to the rotating body (130).

It is preferable that the connection line 230 is formed of a wire and the coupling ring 210 coupled to the first and second bolts 110a and 120a is connected to the first and second bolts 110a and 120a, So that it is connected to the support bolt 221.

The coupling ring 210 and the supporting bolt 221 may be formed with hooks 211 and 221b to which the connecting line 230 is connected.

Therefore, the first and second afore-mentioned members can be prevented from being detached from the rotating body 130 while being fixed to the rotating body 130.
