That is, as shown in FIGS. 2 to 4, the connection insulator of the extreme-voltage power distribution wire according to the present invention includes the insulator assembly 100.

The insulator assembly 100 includes an insulator main body 110 formed of an insulating material and a special high voltage power line L disposed on the insulator main body 110 to be seated on the insulator main body 110 An insulation cover unit 200 provided to surround the insulator main body 110 and the bracket 120, a displacement sensing unit 300, an alarm unit 400 and a control unit 500, .

This ensures that insulation efficiency of the insulator body 110 is further increased by the insulator cover unit 200 and that before the insulator cover unit 200 is separated from the correct position for protecting the insulator body 110 and the bracket 120 This can be easily recognized by the administrator so that necessary measures can be taken in advance.

The insulator main body 110 is provided on the wire (see FIG. 1) to support the wire and the machined wire L for super high voltage distribution so that they are not in electrical contact with each other. As shown in FIG. 5, the protrusion 111 protrudes in a vertical direction and has a concave portion 113 recessed therein.

In addition, the bracket 120 is provided with a structure in which one side can be pivotally opened to the other side so as to receive and install a special high-voltage distribution work line L that is seated on the upper portion of the insulator body 110, After the dedicated working wire (L) is accommodated, one side is closed by the engaging means or the like.

In addition, a pair of small plates, which are spaced apart from each other so that a piezoelectric element 320, which will be described later, of the displacement sensing part 300 is installed between the bracket 120 and the sensor contact part 121 are provided.

In addition, the insulation cover unit 200 is formed with a cable through hole 201 through which the special high-voltage power distribution work line L supported by the bracket 120 can be easily penetrated. As shown in FIG. 3, And an electromagnetic wave shielding layer 220 formed on both sides of the insulating layer 210 in a cross section. The electromagnetic wave shielding layer 220 is formed on the upper surface of the bracket 120 to cover the bracket 120, And an insulator cover 240 provided at a lower portion of the bracket cover 230 and surrounding the insulator body 110. [

Accordingly, the insulating cover unit 200 made up of the insulating layer 210 and the electromagnetic wave shielding layer 220 can effectively shield electromagnetic waves generated from the special-high-pressure distribution working wire L, The influence of electromagnetic waves on the human can be minimized and the overall breakage of the insulator main body 110 can be minimized by protecting the insulator main body 110 from the corona even if the insulation of the insulator main body 110 is partially broken.

The electromagnetic wave shielding layer 220 may be formed on the outer and inner surfaces of the insulating cover unit 200 as an insulating layer 210 by a method such as spraying zinc, plating, or conductive paint.

The bracket cover 230 is provided in a substantially cylindrical shape with its bottom opened so as to enclose the bracket 120 and the insulator cover 240 has a shape of a convex portion 111 at the uppermost position in the insulator body 110 And the bracket cover 230 and the insulator cover 240 are integrally formed with each other.

3, the van der Waals bonding portion 241 is provided on the inner surface of the upper portion of the insulator cover 240 where the insulating cover unit 200 is in contact with the insulator body 110. As shown in FIG.

The Van der Waals bonding portion 241 is formed by a carbon nano process such that a strong van der Waals adhesive force is applied between the insulating cover unit 200 and the insulator body 110 by about 10 탆 in length and about 5 탆 in diameter And is provided on the upper inner surface of the insulator cover 240 with a plurality of bristles formed thereon.

When the insulator cover unit 200 covers the insulator body 110 and the bracket 120 so that the insulator cover unit 200 covers the insulator cover unit 200, And the upper surface of the insulator main body 110 is strongly acted so that the center of the upper surface of the bracket cover 230 of the insulative cover unit 200 meets the center of the insulator body 110 on a vertical line It is possible to minimize the detachment of the insulating cover unit 200 from the position (see FIG. 3).

2 and 3, at the lower end of the insulating cover unit 200, an engaging portion 243 in the form of a fringe, which is radially cut away when viewed from below, is formed.

When the insulator cover unit 200 covers the insulator body 110 and the bracket 120 so as to enclose the insulator body 110 and the bracket 120, the lower end of the insulator cover 240 is first inserted into the insulator body 110 And the lower end of the insulator cover 240 is inserted into the concave portion 113 of the insulator main body 110, the insulator cover 240 is brought into contact with the convex portion 111 of the insulator main body 110 and is opened by the gaps of the respective insulator binding portions 243. However, The lower end of the insulator body 240 is elastically contracted to closely hold the insulator body 110.

3, the displacement sensing unit 300 includes a fixing unit 310 fixed to the center of the upper surface of the bracket cover 230 and a fixing unit 310 fixed to the bracket cover 230 by the fixing unit 310. [ A piezoelectric element 320 generating electric power by pressing the sensor contact portion 121 provided on the bracket 120 when the insulating cover unit 200 is tilted off the predetermined position, The connecting rod 330 connected to the piezoelectric element 320 is connected to one end of the bracket cover 230 and the other end of the connecting rod 330 is connected to the piezoelectric element 320, .

5, when the insulating cover unit 200 slips from the upper surface of the insulator main body 110 and is displaced from the correct position due to sagging of the extreme-pressure power supply processing electric wire L or the like, The piezoelectric element 320 which is fixedly connected to the sensor contact portion 230 and is installed between the sensor contact portions 121 may be pressed by the sensor contact portion 121 to generate electricity to operate the alarm portion 400.

At this time, the piezoelectric element 320 uses artificial crystals such as barium titanate and the like by using a Piezo effect in which a voltage is generated by electric polarization when a pressure is applied to the crystal.

Meanwhile, the displacement sensing unit 300 may be connected to the control unit 500 via the fixing unit 310 so that the displacement sensing unit 300 can transmit and receive wireless signals.

5, the alarm unit 400 is provided to be exposed to the outside from the top of the bracket cover 230. The alarm unit 400 receives an electrical signal generated by the displacement sensing unit 300, And informs the outside.

Accordingly, when the insulative cover unit 200 deviates from the correct position for protecting the insulator body 110 and the bracket 120, the administrator can easily recognize the insulator cover unit 200 from the outside.

In this case, it is preferable that an LED warning light is provided at the top of the alarm unit 400, and the warning signal generated by the alarm unit 400 may be a light signal.

However, the present invention is not limited to this and may be an acoustic signal, or a transmission signal sent to a manager at a remote place.

4, when the control unit 500 determines that the inclination of the insulating cover unit 200 is out of the allowable range based on the result detected by the displacement sensing unit 300, The alarm unit 400 may be provided on the complete chassis where the insulator main body 110 is installed to control the alarm unit 400 so that a warning signal is generated at the remote sensing unit 300 or the alarm unit 400 at a remote location.

Accordingly, when the displacement sensing unit 300 senses that the insulating cover unit 200 deviates from the correct position for protecting the insulator body 110 and the bracket 120, the controller 500 can easily recognize the insulator cover unit 200 from the outside, The alarm unit 400 can be operated under the control of the control unit 400. [

For example, the permissible range of inclination of the insulating cover unit 200 may be about +5 to -5 degrees.

The angle at which the insulation cover unit 200 tilts can be determined by the controller 500 based on the magnitude of the voltage generated in the piezoelectric element 320 of the displacement sensing unit 300.

The operation of the insulator assembly 100 constituting the connection insulator of the high-voltage power distribution wire according to the present invention will now be described with reference to FIGS. 2 to 5. FIG.

In the state where the center of the upper surface of the bracket cover 230 of the insulating cover unit 200 is in a straight position on the vertical line with the center of the insulator body 110, no warning signal is generated in the alarm unit 400 .

Next, when the insulating cover unit 200 is detached from the correct position due to the squeezing or the like of the extra high-voltage power distribution work line L, the bracket cover 230 of the insulating cover unit 200 is inclined, 230 are also tilted together. Pressure is applied to the piezoelectric element 320 by any one of the plates of the sensor contact portion 121 formed of a pair of plates.

When a pressure is applied to the piezoelectric element 320, electricity is generated in the piezoelectric element 320. The electric signal is transmitted to the controller 500 and converted into a warning signal by the alarm unit 400 Respectively.

As described above, according to the present invention, the insulating cover unit 200 can effectively shield the electromagnetic waves generated from the special-high-voltage distribution work line (L) so that the influence of the electromagnetic waves on a person located at a nearby distance can be minimized And can be easily recognized by the administrator before the insulating cover unit 200 is removed from the correct position to protect the insulator body 110 and the bracket 120 to take necessary measures in advance.

Here, since a plurality of insulator bodies 110 used for insulation are mainly made of porcelain, they have a disadvantage in that they are excellent in insulation property but weak in impact strength and fragile.

This can be attributed to the easily deteriorated nature of the product because it repeats thermal expansion during the cold and hot periods under outdoor exposure conditions.

6, the insulator 115 protrudes from the lower center of the insulator main body 110 and the insulator groove 117 is formed at the center of the insulator 110 to be vertically stacked The chamber 119 is filled with a thermally colloidal liquid CL and the thermally colloidal liquid CL is introduced into a kind of heat capacity capacitor. The heat insulating force is maintained by the thermally colloidal liquid (CL) even if the temperature of the outside air is greatly changed by performing the role, so the heat distortion of the insulator body 110, that is, heat shrinkage and thermal expansion, It can be constituted so as to suppress the occurrence of cracks and to have characteristics that are resistant to impacts.

15% by weight of striped laminaroxysilicate titanium, 10% by weight of gadolinium sulfate, 15% by weight of a mixture of xylitol and erythritol in a weight ratio of 1: 1, glacial acetic acid, 10% by weight, lithium bromide (LiBr) 10% by weight and the remaining liquid paraffin.

In this case, the striped lambda gadolinium titanium oxide is a phase-transition material having a stripe shape, which is a heat-retaining material that repeats heat storage and heat release according to a change in temperature around room temperature. The gadolinium sulfate is a sulfuric acid of gadolinium (Gd) , Gadolinium is a rare earth transition metal belonging to Group 3 of the periodic table and is a ductile silver-white element that slowly reacts with oxygen and water, ferromagnetic at temperatures below 17 ° C, Superconductivity. Such gadolinium sulfate is self-cooling and reinforced, so that a cooling effect can be obtained.

The xylitol and erythritol react with moisture with sugar alcohol to cause an endothermic reaction, thereby depriving the surrounding heat, thereby increasing the cooling property.

The Glacial Acetic Acid has a characteristic of freezing at room temperature of 14.5 ° C or higher and enhances the cooling property. Lithium bromide (LiBr) is highly hygroscopic and attracts moisture from the surrounding area to increase the cooling property Is added.

In addition, the liquid paraffin as a typical PCM (phase change material) enhances the cooling and regenerating properties.

In addition, an injection port IJ is formed at one side of the insulator main body 110 so that the thermally colloidal liquid CL can be injected and sealed.

The upper end of the mandrel 600 is inserted into the insulator groove 117 of the uppermost insulator body 110. The upper end of the mandrel body 110 is inserted into the insulator groove 117 of the uppermost insulator body 110, (PNT).

A control screw 610 is formed on a lower part of the mandrel 600 and a bearing ring 620 is fastened to the adjusting screw 610. The bearing ring 620 is inserted into the mandrel 600 For controlling the height of the plurality of insulator bodies 110.

6 and 7, the height varies depending on the number of the insulator main body 110 fitted. When the upper end of the mandrel 600 and the upper end of the uppermost insulator main body 110 do not coincide with each other, The support ring 620 may be provided to rotate the support ring 620 to change the support position of the bottom of the lowermost insulator main body 110 so that the installation height of the insulator main body 110 can be easily and quickly set .

Particularly, in the present invention, in order to securely fix the mandrel 600 to the wrought iron 7, as shown in Figs. 8 and 9, the wand iron 7 is divided into the upper wand iron 7a and the lower wand iron 7b And they are assembled to each other in a sliding fit manner to constitute one brass bar 7.

To this end, a worm wheel assembly groove (HOM) shaped like a tongue is formed on both ends of the upper wedge iron 7a, and a worm wheel assembly protrusion DOL having a corresponding shape is formed on both upper end surfaces of the lower wedge iron 7b So that they are assembled in a sliding manner.

Therefore, it is not separated in the vertical direction after the assembly, but can be slid in the longitudinal direction.

9, a locking member FX is further provided on one side of the lower crown iron 7b to prevent the sliding in the longitudinal direction and to secure a strong positional stability, A stator (MXT) is further installed to firmly and securely fix each other.

The locking member FX includes a fixed latch FRT that is screwed to one side of the outer surface of the lower crown iron 7b and a floating latch MRT is provided with a hinge axis RT And a torsion spring TSP fitted to the hinge axis RT is provided between the fixed latch FRT and the floating latch MRT so as to be rotatably connected to the fixed latch FRT with a floating latch MRT Are provided so as to be elastically rotatable.

A stator MXT protrudes from the outer surface of the upper bridge iron 7a so that the floating latch MRT can be engaged with the outer surface of the upper bridge iron 7a and a latching protrusion DT protrudes vertically from the outer surface of the stator MXT. The stator MXT is elastically deformable.

Accordingly, when the upper and lower rigid iron 7a and the lower rigid iron 7b are in contact with each other, when the rotary latch MRT is rotated and pressed, the leading end of the floating latch MRT falls over the locking projection DT, , When the tip of the floating latch (MRT) is lifted up slightly and only the part hanging on the latching protrusion (DT) is turned over, the normal state of the chain is automatically canceled.

This is possible because the stator MXT is a resiliently deformable structure, and the bottom edge of the locking projection DT is preferably chamfered for the original activation of the operation.

Therefore, the clamping structure between the lock member FX and the stator MXT facilitates quick and easy tightening or unlocking operations.

Of course, the lock member FX and the stator MXT should be formed on both sides of the bare iron 7, respectively.

An insulator plate 710 formed of a synthetic resin is screwed to the bottom surface of the lower bridge iron 7b and the insulator plate 710 An insulating boss 720 protrudes from the center of the plate surface and the lower end of the mandrel 600 passes through the insulator installation hole 700 and then is screwed into the insulation boss 720.

Further, in order to further enhance the insulation property, the insulator mounting hole 700 may be further formed with a cylindrical insulating bush 730 formed of a polystyrene resin and having an inner and outer surfaces wavyly embossed.

In addition, since the solid iron 7 is a metal material, it can be easily corroded when exposed to the outside. Of course, when manufactured using corrosion-resistant steel, the corrosion rate can be reduced, but the cost increases sharply.

Accordingly, in the present invention, a reinforcing coating layer (CT, see FIG. 6) can be further formed on the outer surface of the brass 7 so as to enhance not only the durability but also the insulation property at a low cost with increased corrosion resistance.

The reinforcing coating layer (CT) according to the present invention is preferably formed by spray coating the following coating composition.

At this time, the coating composition to be spray coated was a mixture of 5 wt% of a mixture of nylon 66 and aluminum powder in a weight ratio of 9: 1, and a mixture of polyisoprene and silica powder having a particle size of 0.1-0.2 μm at a weight ratio of 4: 1 10 wt% of a molded product in the form of a mixture of barium ricinoleate, 2.5 wt% of sodium silicate, 1.5 wt% of N-ethyl-carbazole methacrylate, 1.5 wt% of tetraisopropyltitanate, 3% by weight of behenic acid, 2.5% by weight of dioctyl azide (DOA), 5% by weight of carboxymethylcellulose salt, 2.5% by weight of styrene monomer, 2% by weight of dicyanamine and the remaining bisphenol A type epoxy resin powder.

At this time, the mixture of the nylon 66 and the aluminum powder in a weight ratio of 9: 1 is added to effectively apply the insect repellency of the nylon 66 and the heat dissipation characteristics of the aluminum powder on the coated surface.

In addition, the polyisoprene and the silica powder having a particle size of 0.1-0.2 μm are mixed in a weight ratio of 4: 1. The polyisoprene is a natural rubber component having excellent insulating properties, and the silica powder Is not only a crystalline structure with a high Mohs hardness but also a very low degree of thermal expansion, thus enhancing the crack resistance against changes in the external atmosphere.

In addition, the barium ricinoleate is added in order to suppress the thermal decomposition of the coating layer as much as possible and prevent the coating layer from easily deteriorated, thereby improving shape retentivity.

In addition, the sodium silicates are added to enhance the heat stability and insulation of the coating layer by inducing gelation to form a coating.

In addition, the N-ethyl-carbazole methacrylate is added in order to prevent cracking of the coating layer while enhancing transparency.

Furthermore, the tetraisopropyltitanate is added as a coupling agent having an organic titanate structure to enhance both the durability and the heat resistance by enhancing the interfacial adhesion between the polymer resin and the inorganic material.

The behenic acid is added to enhance the lubricity of the resin to improve the coating property, and the dioctyl azide (DOA) is added to increase the cold resistance of the coating layer while increasing the plasticity of the resin.

In addition, the styrene monomer is added to increase the cross-linking density of the coating layer to increase impact resistance and abrasion resistance.

By such a constitution, it becomes possible to maximize the heat-resistant stability and the insulation stability while increasing the rigidity of the insulator.
