Description

Extra-high tension support type lead in pole electric power distribution line

[0001] The present invention relates to a high-voltage supported input lead of a distribution line in distribution technology, and more particularly to a high-voltage supported lead- And to provide a high-voltage support type lead-in line for the distribution line.

Generally, in order to increase the efficiency of electricity transmission, the power plant transmits with higher transmission voltage.

However, since such high-voltage electricity can not be used in real life, it can be decompressed through a pillar-type transformer so that it can be used at home.

However, in a place where electric power of a relatively high voltage is used as compared with a home such as a factory, a self-transformer is operated instead of a pillar transformer.

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

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, since the contact area between the rotating body and the cap is large when the position of the first and second insulators is changed, the rotation of the rotating body due to friction is not easy.

Further, in order to prevent contact between the rotating body and the cap, there is a problem that the bolt for coupling the cap to the coarse iron must be loosened, and the cap and bolt may be detached from the coarse iron when the bolt is loosened.

However, according to the present invention, the 'special high-voltage induction mains supported by distribution lines' are replaced with 'special high-pressure supported induction mains for distribution lines' among the configurations disclosed in the above-mentioned Japanese Patent No. 0809098, And a description of the operation is further included, and this part is the most important constitutional feature.

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.

1 and 2, a description will be given of an extra-high voltage supporting type lead wire to a distribution line.

Extra-high voltage support type of distribution line is provided with additional insulator as insulator supporting 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. 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 the distribution line is fixed to the loop, after replacing the insulator, take measures so that high-voltage current can flow through the distribution line.

The bare iron supported by the extra high pressure inlet is composed of cap (150) and 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 components of the extra-high pressure intake except for the mains.

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 an upper portion of the rotating body 130 and a second insulator 120 is coupled to a lower portion of the rotating body 130.

A rotating bar 170 is coupled to the outside of the barrel 160 and a cap 150 is coupled to the other side of the barrel 170.

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 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. However, 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. That is, 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 as much as possible.

The first bolt 110a of the first insulator 110 is pressed and fixed to the swivel base 170 of the wrought iron 160 as shown in FIG.

The second bolt 120a of the second insulator 120 is press-fitted to the swivel base 170 of the wrought iron 160. [

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 can be rotated on the rotating table.

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.

In the present invention, the structure of the guide unit 200 for guiding the rotation of the rotating body 130 smoothly as shown in FIGS.

When the damaged insulator is replaced by replacing the position of the guide part 200 with respect to the first and second insulators 110 and 120, rotation of the rotating body 130 is smoothly performed in a state where the first and second bolts 110a and 120a are loosened .

That is, when the first and second bolts 110a and 120a are loosened, the guide unit 200 is rotated by the rotation of the rotating body 130 such that the contact area with the cap 150 is minimized, (130) is prevented from being smoothly rotated.

The guide part 200 includes a guide ball 210 and an outlet 221 formed at one end of the guide part 210 so that the guide ball 210 is received inside and the outlet 221 faces the rotating body 130 The guide ball 210 is received in the casing 220 and the casing 220 which are respectively buried on the upper and lower sides of the cap 150 so that the guide ball 210 protrudes outward through the outflow inlet 221 while pressing the guide ball 210 (Not shown).

The other end of the cap 150 is coupled to the rotating table 170 by the bolts 180 and is coupled to the outside of the other end of the rotating table 170 with one end being opened.

Therefore, it should be understood that the rotating body 130 and the cap 150 are directed to the electric pole at one end and to the bolt 180 at the other end.

The casing 220 is formed so that both ends thereof extend in a direction intersecting the longitudinal direction of the first and second bolts 110a and 120a and are positioned at the other side of the first and second bolts 110a and 120a, It is preferable to fill it in the upper and lower sides.

At this time, the first and second insulators 110 are disposed on the upper and lower sides of the rotating body 130 and are positioned on the same line as the casing 220 in the longitudinal direction of the wrought iron 160 when viewed from the upper or lower side ≪ / RTI >

The casing 220 may have an open / close cap 240 for opening / closing the other end thereof.

The casing 220 is threaded on the inner circumferential surface of the other end, and the opening and closing cap 240 can be screwed to the casing 220 while a thread is formed on the outer circumferential surface.

The guide part 200 can smoothly guide the guide ball 210 and the spring 230 to the inside of the casing 220 as well as the wear of the guide ball 210 and the spring 230 So that it is possible to smoothly carry out the replacement with the lowering of the elastic force of the elastic member.

The guide ball 210 has a spherical shape and protrudes outward through one end of the cap 150 while protruding outward through the outflow inlet 221 as the spring 230 is pressed.

The cap 150 may be spaced apart from the other end of the rotating body 130 such that one end of the cap 150 is not in contact with the other end of the rotating body 130 in a state where the bolt 180 is coupled to the rotating table 170.

In other words, it is preferable that the cap 150 is coupled to the bare iron 160 by the bolts 180, but is not pressed while being in contact with the rotating body 130.

This is for the purpose of smoothly rotating the rotating body 130 without loosening the bolts 180 in a state where the first and second bolts 110a and 120a are loosened.

Accordingly, it is possible to prevent disengagement of the cap 150 and the bolt 180 due to the loosening of the bolt 180, together with the inconvenience of loosening the bolt 180.

The rotating body 130 has a pair of semicircular grooves 131 and a pair of semicircular grooves 131 for stopping the rotation of the rotating body 130 while the guide ball 210 is drawn into the other end of the rotating body 130, A guide groove 132 is formed to guide the guide ball 210 in accordance with the rotation of the guide plate 130.

The pair of semicircular grooves 131 are disposed on the upper and lower sides of the center of the rotating body 130 and the guide grooves 132 are formed in an annular shape and communicate with the pair of semicircular grooves 131.

The guide groove 132 has a semicircular shape in its longitudinal section and is formed to have a depth shorter than that of the semicircular groove 131 to guide the progress of the guide ball 210 while the guide ball 210 is inserted into the semicircular groove 131 Guide.

The pair of semicircular grooves 131 are formed on the other end of the rotating body 130 so that the rotating body 130 is rotated by 180 degrees when the first insulator 110 and the insulator 120 are changed in position, The guide ball 210 disposed on the upper and lower sides of the guide plate 150 is retracted to stop the rotation.

 The first and second insulators 110 and 120 are maintained in a state in which the guide ball 210 is moved into the semicircular groove 131 by the rotation of the rotating body 130 and the position thereof is changed.

The spring 230 is retracted while the guide ball 210 is pulled into the semicircular groove 131 while the guide ball 210 is retracted into the guide groove 132.

The guide unit 200 may further include binding means 250 for binding the guide ball 210 drawn into the semicircular groove 131.

The binding means 250 is formed of a magnet and embedded in the surface of the guide groove 132, and the guide ball 210 is preferably made of a metal attached to the magnet.

The guide unit 200 can be rotated by the rotation of the rotation unit 170 while the guide ball 210 is drawn into the half circle groove 131 even when the rotation unit 130 is separated from the cap 150. [ Can be prevented.

The guide unit 200 is configured such that when the rotating body 130 is rotated by artificial pressing in a state where the first and second bolts 110a and 120a are loosened, The rotation of the rotating body 130 can be smoothly performed so that the contact area between the rotating body 130 and the cap 150 is minimized.
