Description

The polymer lightning arrester installation structure and LP insulator for integrated type electric pole}

The present invention relates to an integral structure of the pole post line insulator (Line Post Insulator (hereinafter referred to as 'LP insulator')) and the polymer arrester installation structure, more specifically, the polymer arrester formed on top of the pole The vertical post-integrated line post insulator and polymer arrester installation structure prevents electric failure caused by foreign matters such as a magpie house, makes installation easier, and reduces maintenance costs. It is about.

In general, electric poles are made of concrete, wood, and iron poles, and are pillars that support a distribution line that directly supplies electricity to a consumer from a nearby substation.

Since these poles are built on the ground and support the wires in the air, abnormal voltages may occur on the wires due to lightning and other surges falling on the poles, so that there is an arrester that prevents abnormal voltages from occurring on the wires. It is installed at the upper end of electric pole applied to processing inlet, underground inlet and high voltage power supply facilities.

In the related art, a lightning arrester is separately installed in a pole, and a power line and an arrester connection wire are installed in a pole, and a plurality of insulators are connected to a sleeve, and the insulator is installed in a complete rod installed in the pole. Is installed by the bracket with the insulator in the complete to be installed separately in the upper end of the pole, the wire connected to the ground to the output of the arrester is complex installation.

Therefore, the completion of installation of the arrester, sleeve and insulator, etc. for the upper part of the pole is installed separately, so the components of the upper part of the pole are very high, so the installation and maintenance cost is high, and the worker's safety accident is caused. It has the disadvantage of being a factor.

In addition, in the prior art, since the wires and the like are very complicatedly entangled in the upper part of the pole, the space becomes narrow, the external objects are easily caught, and the magpie house is built intensively in the installed pole. There is a disadvantage in that power failure and breakage frequently occur due to a short circuit of the wire.

As an installation structure for electric pole arresters for solving the above problems, there is Korea Patent Publication No. 10-0893753 (2009. 4. 9. registration).

The pole arrester installation structure neatly arranges the wires formed on the top of the pole and prevents the top of the pole from being complicated to prevent electric failure due to foreign matters such as magpies, and facilitates the installation work and maintenance cost. It is effective to reduce the cost.

However, the insulator (hereinafter referred to as a 'suspension insulator') used in the pole arrester installation structure is coupled to a claw in the finish, the insulator reinforcement that is the hook and suspension insulator is connected by a pin, and the arrester is in line with the suspension insulator. Is connected, and a dead end clamp is connected to one end of the arrester by a pin, and the structure of fixing the power line with a U-shaped bolt to the dead end clamp.

The insulator, ie the suspension insulator used in the pole arrester installation structure, insulates the extra high voltage power line to be held in the light and light iron pole of the electric pole in the built-in portion of the distribution line or the human part, thereby supporting the power line. It is completely different from insulators.

When the lightning arrester is connected to the suspension insulator in a horizontal manner, the lightning arrester is discharged by a lightning strike, and the dead-and-clamp and pins are pulled in the state where the power line is pulled by using a live work vehicle and a vice to replace the arrester. Loosen the U-shaped bolt, replace the arrester connected to the suspension insulator and install it in reverse order to adjust the tension of the power line.

Therefore, it takes a lot of time for the installation and dismantling of a vise for catching the power line and the power line required to replace the lightning arrester, and the tension adjustment of the power line, which is cumbersome, inconvenient, and has a disadvantage in economical cost.

The present invention has been made to solve the above problems, by combining the LP insulator and the polymer arrester installed in the upper part of the pole, so that the upper part of the pole is not complicated to prevent electrical failure by foreign matters such as magpie house, convenient installation work In addition, it provides a pole line post insulator and polymer arrester mounting structure that reduces material costs by reducing maintenance costs and eliminating other components installed with the polymer arrester.

The present invention uses an insulated hanger on the side of the LP insulator supporting the power line to achieve the above object by vertically integrally forming the polymer arrester using the LP insulator pin screwed to the lower coupling bracket of the LP insulator The means for simple fixation on the finish installed in the system was devised.

In addition, the present invention is to quickly and simply replace the polymer arrester by releasing the clamp of the insulation hanger holding the LP arrester polymer arrester when the lightning arrester is discharged by lightning.

The above-described integral pole line post insulator and polymer lightning arrester installation structure of the present invention does not complicate the upper portion of the pole to prevent electric failure caused by foreign matter such as a magpie house, and facilitates installation work and maintenance cost. Reduces material costs by eliminating other components installed with the polymer arrester, and reduces the product by simply replacing only the polymer arrester coupled to the side of the LP insulator by an insulating hanger when the lightning arrester is discharged. It can have an economic effect.

An integrated pole post insulator (LP insulator) and a polymer lightning arrester installation structure of the present invention are described below in detail with reference to the accompanying drawings.
