Description

Jumper wire protector of line post insulator {APPARATUS FOR PROTECTING JUMPER WIRE OF LINE POST INSULATOR}

The present invention relates to a jumper wire protection device of the line post insulator, and more specifically, to separate the parts for fixing the body of the line post insulator and the jumper wire so as to selectively maintain or replace only necessary parts and to wire the jumper wires. It relates to a jumper wire protection device of the line post insulator which can facilitate the

In general, the large power generated in the power plant is transmitted to each substation with high voltage power through transmission lines such as power transmission towers, and then the cable is used in the home or building through a multi-stage transformation process at the substation. It goes through the distribution process to supply to each region.

At this time, the power supply to general customers is supplied through telephone poles installed at regular intervals, and the connection of transmission and distribution wire cables in each telephone pole is connected by using jumper wires. That is, the transmission and distribution wire cable to be connected to the telephone poles are coupled through the insulators on both sides of the complete side installed on both sides of the top of the telephone poles, and the jumper wires are connected between the insulators, but the jumper wires connected to the upper ends of the complete poles. It was used to construct so that it can be supported through the insulator to be installed.

In addition, the line post insulator is an insulator that insulates the transmission and distribution line while being installed on the upper side of the telephone pole through a supporting member such as a stiffener. The jumper wire is fixed in the horizontal direction through the fixing wire as a means to insulate the wires. That is, the transmission and distribution wire cable is equipped with a horizontal rod mounted on the upper side of the body of the telephone pole, and a plurality of line post insulators are mounted on the upper side or the lower side of the complete pole, and the transmission and distribution wire cable and the ground on the upper side of the line post insulator. The jumper wire which insulates is fixed.

In detail, the fixing structure of the line post insulator and the jumper wire is formed. A seating hole is integrally formed at the upper end of the body of the line post insulator, and the jumper wire is fixed to the seating groove formed in the upper surface of the insulator seating hole by the fixing wire. This is to be fixed to prevent.

However, the line post insulator according to the prior art has the following problems. Since the insulator seat is formed integrally with the linepost insulator, when the insulator seat or the body of the insulator is damaged or deformed, the insulator needs to be replaced.

And the direction of the mounting groove is determined at the time of insulator installation. If the direction of the mounting groove does not match the wiring direction of the jumper wire, the wiring direction of the jumper wire will not be changed. There is also the inconvenience of having to reassemble to match the orientation.

In addition, the jumper wire is very cumbersome and inconvenient because the jumper wire should be fixed by being pulled from one side of the fixing wire to the other side.

In addition, the fixed wire is exposed to the air as it is, for example, if the corrosion of the jumper wire to produce a corrosion product due to the reaction with rain water or foreign matters, the life of the jumper wire is shortened, so the various costs associated with the maintenance of the transmission line There is an increasing problem.

According to the invented patent No. 889255 for solving the above problems, a bolt groove for fixing the bolt is provided at the center of the line post insulator, and the bolt that is coupled to the bolt groove is disposed above the base plate. And it is possible to adjust the position of the seat according to the position of the jumper wire by allowing the seating groove formed in the seating groove for the placement of the jumper wire to be fixed in place, and has a structure for fixing the seat with a fixing cap coupled with the bolt, In addition, the fixing cap for preventing the inflow of rainwater is to be screwed with the fastening rod provided in the seating.

According to the registered patent as described above, when the insulator, the base plate and the seating hole is fixed only by the bolt, when the fastening between the insulator and the bolt is incompletely affected, the fixing state of the jumper wire is also affected. There is a very troublesome problem.

The present invention has been made to solve the above problems of the prior art, and can be firmly fixed regardless of the position of the jumper wire, while its purpose is to provide a jumper wire protection device of a line post insulator with a simple installation structure. .

In order to achieve the above object, the present invention is a device for protecting a jumper wire fixed to the line post insulator is installed in the complete fixed to the upper pole, the insulator is formed with a circular spiral groove in the upper center, A circular fastening groove having a flat portion and a threaded portion sequentially formed thereon is formed along the circumference of the spiral groove, and a circular first uneven portion is formed on an upper surface between the spiral groove and the fastening groove, while the spiral groove and the fastening groove are formed. The first and second cylindrical portions are inserted into each of the first and second cylindrical portions are provided, the plurality of first grooves are formed in the horizontal direction on both sides of the outer surface extending upward from the first and second cylindrical portions in a cylindrical shape, A second groove is formed to vertically intersect the first groove, and a top surface is formed with a seating groove in which a jumper wire is disposed across the center thereof, and the bottom surface is fitted with the first uneven portion. Lee, and the lower member a second concave-convex portion is formed; A through hole which is inserted into the second groove and communicates with the same diameter as the first groove is formed and is provided with a vertical portion fixed to the lower member by a fixing pin inserted into the first groove, the dome shape extending from the vertical portion. And an upper member having an upper portion and extending downward from an upper surface of the inner central portion, and having an extension portion configured to press the jumper wire disposed in the seating groove by the support portion rounded on the lower surface thereof.

In this case, an extension groove is formed at the outer end of the first groove, and the fixing pin is provided with an elastic hook at the front end thereof, so that the fixing hook can be pulled out to the inner end of the first groove and at the same time the elastic hook is pulled out. It is characterized in that the separation of the fixing pin from the first groove as it is unfolded in the expansion groove by the restoring force.

In addition, the upper side of the support may be helically coupled to the extension, it is characterized in that the use of the support is different, the radius of curvature of the lower surface.

As described above, the jumper wire protection device of the line post insulator according to the present invention, when the lower member and the insulator are helically coupled to the first and second cylindrical portions, the coupling between the seating grooves and the jumper wires is performed when the wiring direction is aligned. While the installation is completed by a simple process of fixing the upper and lower members with the fixing pin in the stopped state, it is possible to drastically reduce the probability of loss by preventing the fixing pin from falling off. For interchangeable reasons it allows for convenient installation and robust jumper wire support.
