Description

Fireproof prevention system of distribution line electric pole

The present invention relates to a fire prevention system for a telegraph pole of a processed distribution line in the field of distribution technology, and more specifically, to guide a distribution line through which a high-voltage current flows, while a fire occurs due to a short circuit or short circuit due to damage to an insulator. It relates to a fire prevention system of an overhead power distribution line so that replacement of a damaged insulator can be done quickly and smoothly.

In general, in order to increase the transmission efficiency of electricity, the power plant transmits with a high transmission voltage.

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

However, in places where electricity of a relatively high voltage is used, such as a factory, a self-transformation room is operated in place of a column transformer.

The power plant uses a special high-voltage lead column to guide the electric wire through which high-voltage current flows when transmitting with high transmission voltage.

The special high voltage injector is equipped with an insulator on the armature to safely flow the high pressure current, and the high voltage wire is fixed on the insulator to flow the high voltage current.

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

The special high voltage lead-in is equipped with several insulators with high resistance to increase the insulation rate to prevent current from flowing to the ground.

However, if the insulator installed in the special high-voltage lead-in is damaged, a problem in insulation rate may occur and current may flow to the ground, so quick replacement of the damaged insulator takes priority.

As a conventional technology that partially improves these problems, Korean Patent Registration No. 10-0809098 (2008.03.04.) discloses a'distribution line-supported extra-high voltage inflow line'.

However, the conventional distribution line-supported special high-pressure injector has a problem in that the cap is not securely fixed to the rotating body as the bolt is incompletely coupled to the steel or loosened by external force.

Accordingly, the cap is not in close contact with the rotating body, there is a problem that the rotating body is shaken or rotated by an external force or the like.

Referring to Figures 1 to 2, the fire protection system of the overhead distribution line of the overhead power distribution line according to the present invention is further provided with an extra insulator as an insulator 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 damaged insulator occurs in the first insulator 110 supporting the distribution line, the first insulator 110 and the second insulator 120 are rotated to rotate the fixed rotating body 130 and the first insulator 110 and the first insulator 110 are disposed. 2 After changing the position of the insulator 120, the second insulator 120, which is an extra insulator, is used to support the distribution line.

  That is, the replacement of the damaged insulator is performed quickly and smoothly so that a fire does not occur due to a short circuit or a short circuit due to the insulator's damage.

It is safe to use the first insulator 110 for the insulator 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 for replacing the insulator, and the first insulator 110 and the second insulator 120 are fixed to the rotating body 130 ) To replace the damaged insulator by changing the position of the insulator to fix the distribution 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 so that the positions of the insulators are changed to replace each other.

The first insulator 110 or the second insulator 120 is provided with a screw thread on an axis for fixing the insulator, so that the screw thread of the insulator and the rotating body 130 are combined and fixed to the rotating body 130.

The clasp 140 is located on the armature 160 to temporarily fix the distribution line when replacing the insulator.

Wancheol 160 is installed to protrude in the horizontal direction to the top of the telegraph pole.

When replacing insulators, no current should flow through the distribution line. When the insulator is damaged, current leakage may occur in the distribution line.

Find where the current is leaking and replace the broken insulator.

The first insulator 110 or the second insulator 120 increases the number of insulators in the first insulator 110 or the second insulator 120 so as to flow a high voltage current greater than the high voltage current supported by the insulator. Allow high-voltage current to flow.

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

After the distribution line is fixed to the ring, the replacement of the insulator is completed so that a high-voltage current flows through the distribution line.

The insulator is supported by a cap 150, which is composed of a cap 150 and a rugged end 160.

The rotating body 130 is positioned between the cap 150 and the armature 160 so that the rotating body 130 can rotate.

When the rotating body 130 rotates, the first insulator 110 and the second insulator 120 fixed to the rotating body 130 rotate to change the upper and lower positions.

The cap 150 is fastened to the swivel 170 of the wrought iron 160 by a bolt 180 to form one wrought iron.

Rotating body 130 is coupled to the swivel 170 of the finished iron 160, and the bolt 180 is fastened to the swivel 170 of the finished iron 160 through the cap 150, so that the cap 150 rotates 130 ) Prevents separation from the swivel 170, so that one rotating body 130 is easily rotated on the swivel 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 large number of insulators.

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

Looking at the components of the incoming and outgoing equipment excluding telegraph poles are as follows.

The first insulator 110, the second insulator 120, the swivel 170, the cap 150, and the armature 160 are coupled to the rotating body 130.

The first insulator 110 is coupled to the upper portion of the rotating body 130, the second insulator 120 is coupled to the lower portion of the rotating body 130, and the rotating table 170 is coupled to the outside of the armature 160 and the rotating table ( The cap 150 is coupled to one side of the 170).

The first insulator 110 and the second insulator 120 coupled to the rotating body 130 have a ring for fixing the distribution line.

When the distribution line is fixed to the ring, the preliminary work that can cause high-voltage current to flow is completed.

The rotating body 130 has a bearing structure that can rotate in a position where the cap 150 and the armature 160 are combined.

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

The swivel 170 is located on the extension line of the armature 160 and constitutes one armature.

The swivel 170 is combined with the armature 160 so as to maintain a fixed position even when an arbitrary force is applied.

The rotating table 170 serves to combine the rotating body 130, the cap 150, and the complete iron 160. The rotating base 170 provided in the complete iron 160 is formed integrally with the first insulator 110. ) 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 swivel 170 of the finished iron 160 to stably rotate the rotating body 130. And the armature 160 is positioned.

The first insulator 110 forms a first insulator member while being provided with a first bolt 110a that is penetrated through one side of the rotating body 130 and is pressed and fixed to the armature 160.

The second insulator 120 forms a second insulator member while being provided with a second bolt 120a that is penetrated through the other side of the rotating body 130 and is pressed and fixed to the armature 160.

The bolt 180 is coupled to the cap 150 so that the rotating body 130 is fixed to the swivel 170 of the armature 160 and the first bolt 110a of the first insulator 110 in the rotating body 130. When the second bolt 120a of the second insulator is separated, the rotating body 130 is prevented from being separated to the outside.

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 ring, an insulator is placed between the ring and the complete iron to act as an insulator.

Insulators acting as insulators have different resistance values depending on the number.

In the present invention, the number of insulators of the first insulator 110 and the second insulator 120 is determined to be the same, but the number of insulators of the first insulator 110 and the second insulator 120 may be configured differently as necessary.

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

The clasp 140 provided on the complete iron 160 temporarily fixes the distribution line so that the insulator can be replaced smoothly.

The clasp 140 may be located on the cap 150 instead of the wrought iron 160. The clasp 140 serves to temporarily fix the power distribution line, so it may or may not be located on the cap 150 or the armature 160, if necessary.

When the clasp 140 is not required, the clasp must be provided in the work device for replacing the distribution line. Since the clasp 140 helps smoothly replace the insulator, the clasp 140 may be provided in the incompleteness of the inlet as needed.

The positions of the first insulator 110 and the second insulator 120 are changed by 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 if necessary.

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

When the distribution lines are located in both the first insulator 110 or the second insulator 120, the load applied to the ruggedness due to the sag of the distribution line can be distributed by the rotation of the rotating body 130.

In the case of dispersing the load applied to the perfect iron, the rotating body 130 can naturally rotate according to the movement of the distribution line.

If the rotation of the rotating body 130 is excessive, the load applied to the rotating body 130 becomes large, and thus damage may occur between the rotating body 130 and the finished steel. It is desirable to avoid the separation of the first bolt 110a of the insulator 110 from the second bolt 120a of the second insulator 120.

Referring to FIG. 3, the first insulator 110 is compressed and fixed by the first bolt 110a to the swivel 170, and the second insulator 120 is swivel 170 by the second bolt 120a. Is fixed to the crimping.

The first bolt 110a and the second bolt 120a while the first bolt 110a of the first insulator 110 and the second bolt 120a of the second insulator 120 are squeezed onto the swivel 170 When is released, the rotating body 130 is rotatable on the rotating table 170.

The cap 150 is fixed to the swivel 170 by a bolt 180 to prevent the rotor 130 from deviating to the outside when rotating in the swivel.

In order to prevent the rotating body 130 from rotating on the rotating table 170, the cap 150 may be compressed and fixed to the armature 160 by the bolt 180.

That is, the rotating body 130 is prevented from being rotated on the rotating table 170 by the cap 150 being compressed and fixed to the rotating body 130 by tightening the bolt 180 of the cap 150. do.

On the contrary, the fixing member 232 is released from the support bar 210 in accordance with the loosening rotation, so that the binding means 220 together with the connection bar 231 can be separated from the support bar 210. Accordingly, the support means 230 installed on the support bar disposed on the upper part of the pair of support bars 210 may be replaced with another insulator due to damage to any one of the first and second insulators 110 and 120. Accordingly, the installation of other support bars can be smoothly performed.
