Description

TECHNICAL FIELD [0001] The present invention relates to a magnetic insulator and a method of manufacturing the same,

[0001] The present invention relates to a transmission-type magnetic insulator for allowing an insulator provided on a steel tower to emit a fluorescent substance when insulation breakage and cracks occur, and to make it possible to visually observe the presence or absence of an insulator from a distance.

Insulators are insulators that are positioned between transmission towers and power transmission lines and serve to connect them. These include insulators, insulators, supports, bushings, and insulators.

The types of insulators are classified into magnetic insulators, polymer insulators, and glass insulators. The most commonly used magnetic insulators are classified as feldspathic, cristobalid, and alumina insulators depending on the additive materials. Polymeric insulators are made of polymeric materials, polymeric polymers, and glass insulators are made of thermally tempered glass with silica as the base material.

The structure of the magnetic insulator is composed of magnet, cap, pinball, split pin and cement containing alumina.

On the other hand, the installed insulator is exposed to the external environment for a long time, causing breakdown of insulation, cracking due to external impact, and the like.

Such a breakdown can cause a power outage, which can make life uncomfortable for each family, affecting industrial production and causing enormous damage. If the breakdown is not corrected or replaced on time, the breakdown will progress to the second breakdown .

Therefore, insulators are regularly inspected at regular intervals, and insulators that have reached the end of their life expect to avoid various accidents by replacing them.

However, some insulators have been damaged due to external shocks or manufacturing problems before their lifespan has expired. In the past, inspectors who have encountered such problems have been able to identify themselves with a pylon, or use a telescopic lens I used to observe the heat of Aja. In order to make more accurate judgment, the direct detection method is used by using the measuring equipment.

Many insulators have been introduced to more quickly and accurately inspect such insulators.

For example, Japanese Patent Application Laid-Open No. 10-0778211 (registered on November 14, 2007) relates to an insulation breakdown sensing device for automatically detecting an insulation breakdown of an insulator by an insulation breakdown sensing device of an insulator and informing the operator thereof .

Another example is disclosed in Japanese Unexamined Patent Application Publication No. 2002-0091878 (published on Dec. 11, 2002), which is related to an insulator monitoring device. It senses the leakage current flowing on the insulator surface installed on the high-voltage transmission line, So that it is possible to monitor the fouling condition of the insulator even at a long distance.

The two publications relate to insulators including a device for notifying information when a problem occurs in an insulator, and include a sensor unit for detecting a problem of insulators and a communication device for transmitting a signal to the outside, And there is a problem that a large cost is incurred.

The specific structure or functional description presented in the embodiment of the present invention is merely illustrative for the purpose of illustrating an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention can be implemented in various forms. And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

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

Referring to Fig. 1, a socket cap is coupled to the upper end of an insulator blade in the form of a magnetic insulator, and a ball pin is provided at the center of the insulator blade.

The engaging portion 112 is provided on the upper portion of the insulator 110 and forms a disk shape that becomes wider as it goes down. The inside is empty. The upper end of the socket cap 120 is connected to the end of the ball pin 130 and the upper end of the socket cap 120 is connected to the lower end of the socket cap 120. [ An engaging groove 122 is formed to facilitate the engagement.

The ball pin 130 is vertically positioned inside the coupling portion 112 of the insulator 110 and has one end connected to the upper end of the socket cap 120, And is connected to the groove 122 to connect the plurality of insulators 100 to each other.

On the other hand, the surface of the insulator 110 has two layers. When the fluorescent material 114 is coated on the surface directly contacting the insulator 110 and the drying is completed, the fluorescent material 114 is irradiated to the sunlight Apply the glaze (116) thinly so that it is not exposed directly.

The insulator 100 is classified into a magnetic insulator, a polymer insulator, and a glass insulator according to the material. According to the additive material, the serpentine is classified into a feldspar, a crystal ballid, and an alumina insulator. And the glass insulator is made of a thermally tempered glass made of silica as a base material.

Referring to Fig. 2, the insulator is located between the pylon and the wire.

A plurality of assembled insulators 100 are connected to each other and the insulator 150 is installed on the pylon 200. The ball pin 130 installed on the insulator 110 may be connected to the coupling groove 122 of another insulator 100 and then installed on the pylon 200 and the wire 300 may be connected to the end of the insulator 150 , The number of insulators 100 of the insulator 150 may be further increased by a required number according to the magnitude of the power transmission voltage.

The calculation of the quantity of the insulator 100 is performed by calculating the voltage withstand voltage target value / voltage withstand voltage, and the number of the insulators 100 is calculated by the number of calculation values obtained by substituting the withstand voltage per each other depending on the type of insulator 100 It may be preferable to install the pneumatic cylinder 150 in connection.

In the case of the ball pin 130, a low-voltage ball pin is used at a voltage of several hundred volts or less, and a high-voltage ball pin is used at a voltage of several thousand volts or more.

FIG. 3 is a view showing the reaction of the fluorescent material in the broken part of the insulator according to the present invention. FIG.

The insulator 100 having a poor surrounding environment or a shortened life span breaks due to breakage such as cracking of the insulator 100. Heat is generated by the broken insulator 100 and the resistance is lowered. Light and heat may be generated in the light source 100.

Therefore, when the crack 118 of the insulator 100 is directly exposed to the external environment, the phosphor 114 reacts with the sunlight or the near-infrared rays so that it is advantageous to quickly replace the damaged insulator 100, And the light generated at this time does not generate heat.

Since the insulator 100 must be composed entirely of an insulating material, the fluorescent material 114 uses a rare-earth metal such as a non-metal, which does not contain a metal of a conductive material, and is made of a metal such as thulium (Tm), neodymium (Nd), ytterbium Yb) and gadolinium (Gd) are mainly used.

Therefore, in order to check whether or not the insulator 100 is damaged, it is necessary to find the insulator 100 emitting light from the telescope at a long distance and replace the insulator 100 without having to climb directly to the steel tower 200.

The fluorescent material 114 covering the surface of the insulator 100 is sufficiently coated with the glaze 116 so as not to be directly exposed to the sunlight but it must be applied in an appropriate amount so that the site where the crack 118 is generated is exposed to the sunlight something to do.

Referring to Fig. 4, a table regarding the manufacturing process of the insulator is shown.

The raw material mixing step (S10) may be performed using quartz (feldspar or stonewall), clay, kaolin. It is possible to mix the raw materials in consideration of the mechanical and electrical characteristics of the insulators such as alumina, and perform ball milling so as to have a dense structure. In addition to the above-mentioned raw materials, various raw materials may be mixed.

The de-ironing and dewatering step (S20) is a step of making a dough in which the conductive material and moisture are removed from the pulverized raw material, and the de-ironing process must be thoroughly performed because it has a great influence on the insulation.

The vacuum churning step S30 is a step for removing the air contained in the dough formed above and preventing the surface of the insulator from being smooth due to air bubbles in the dough during the firing process.

A shape making step (S40) for making the shape of the insulator, and a drying step (S50) for controlling the prepared insulator at an appropriate temperature and humidity and drying.

Remove the scratches on the smooth surface to facilitate the application of various materials to the dried insulator.

 After the fluorescent material is applied and dried, it is subjected to a squeezing and sanding step (S60) in which the entire surface is covered with the glaze again.

In the sintering step (S70) in which the coated insulator is baked and cooled for a predetermined time, the coating is heated at a maximum of 1350 ° C in a tunnel knife, and then slowly cooled to suppress crystallization on the surface of the glaze. .

After completing the assembling step (S80) of assembling the fused insulator to each part, the inspection step (S90) for confirming whether or not the completed insulator is abnormal completes all the operations.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
