Description

[0001] The present invention relates to an insulator having a self-cleaning function (line post insulator device)

The present invention relates to an insulator disposed in a mains lead, and more particularly, to an insulator that automatically removes contaminants when the insulator is contaminated, thereby maintaining a stable insulation performance of the insulator and a self-cleaning function capable of suppressing breakage of the insulator Lt; / RTI >

Power generated by the power plant is transmitted to substations in each region along transmission lines including large-scale power transmission towers, and then transformed at various stages in a substation, and supplied to demand sites such as factories, buildings or apartments.

In one of several ways to supply power to the consumer, a number of poles have been installed at the required spacing and a wire cable is supported on the pole. In order to support the wire cable by using a telephone pole, the insulator is fixed to a horizontal bobbin fixed to the upper end of the telephone pole, and a jumper wire for connecting the wire cable is supported on the insulator.

Insulators are components between high voltage cable cables, between a wire cable and a pylon or between a wire cable and a transmission and distribution equipment, to maintain electrical insulation, to maintain physical spacing, or to provide support. Ceramic, glass or synthetic resin And wrinkles are formed on the other surface to improve the electrical insulation property.

In recent years, a polymer insulator having a relatively good insulation and mechanical characteristics, light weight, and easy processing and installation has been used more than a ceramic insulator. The polymer insulator is formed of a polymer as a main body, and has a plurality of polymer shoulders formed on the outer circumferential surface thereof, and has a clevis or mouth type coupling metal at both ends of the main body.

However, the polymer insulator can be destroyed at any moment due to excessive electrical or mechanical stress or by heat generated by a large power arc, and can be damaged due to temperature changes through the summer and winter, pollution in the atmosphere, salinity in the salt- , And may be easily deteriorated by an abnormal voltage caused by lightning or an outdrive.

On the other hand, the insulator gradually deteriorates the insulation function because foreign matter sticks to the surface of the insulator as the time after installation becomes long. Particularly when salt or dust begins to adhere to the surface, the moisture is very easily coated and the dielectric strength is greatly reduced.

If the electric insulation leaks due to a decrease in the dielectric strength, an electrical safety accident such as a power failure occurs, resulting in a great economic loss. As such, the contamination of the insulator is associated with major power outages or safety accidents, so regular or irregular cleaning and management of insulators is essential.

Conventional insulator cleaning has been carried out in such a manner that a worker rides up a staircase of a steel tower, or rides on a basket of a work boom, and injects wash water using a spray gun while approaching the insulator.

However, this type of manpower is very difficult and difficult in itself, and there is a problem that the risk of electric shock and fall is very high. For example, in the case of a double insulated insulator, it is difficult to clean two insulated insulators at the same time, so that a lot of time is consumed in the cleaning work. In addition, in some cases, in the course of washing a single insulated insulator, If flashover occurs due to indirectly sprayed washing water or contaminated dust, it may be killed by electric shock.

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

Basically, the insulator 18 having the self-cleaning function of the present invention operates when the insulator ability of the insulator deteriorates due to contamination of the insulator surface, thereby removing contaminants on the insulator surface, .

The basic structure of the insulator 18 includes a plurality of insulators fixed to the barb of the electric pole; An insulator pressing band which elastically presses the insulator around the insulator so as to prevent the fragments from being separated when the insulator is physically damaged; A leakage current detector closely attached to the surface of the insulator while being supported by the insulator pressing band and sensing a flow of a leakage current on the insulator surface; A signal relay module fixed to the solid iron and connected to the leakage current detector to receive detection information from the leakage current detector; A controller for receiving leakage current information through the signal relay module and outputting a control signal based on information; A plurality of injection nozzles disposed close to the insulators; A washing water tank which is located at a lower portion of the insulator and accommodates washing water supplied from the outside; A pipeline connecting the wash water tank and the spray nozzle; A pump operated by the controller and pumping wash water in the wash water tank to cause washing water to be sprayed through the spray nozzle to remove foreign matter from the insulator surface; And a solar power generator installed at an upper end of the mainsheet to generate electricity by receiving sunlight when necessary and transmitting the generated power to the leakage current detector, the signal relay module and the pump.

FIG. 1 is a front view showing a total construction of an insulator 18 having a self-cleaning function according to an embodiment of the present invention, and FIG. 2 is a side view of the insulator shown in FIG. Fig. 3 is a partially enlarged view for explaining the detailed configuration of the insulator shown in Fig. 1, and Fig. 4 is a cross-sectional view of the mounting structure of the insulator pressing band 24 and the current detector 32, Fig.

As shown in the drawing, the insulator 18 having the self-cleaning function according to the present embodiment includes a plurality of insulators 20 fixed to the barrel 12 of the electric pole 10, a plurality of insulator compression bands 20 surrounding the insulator 20, The pump 24, the leakage current detector 30, the signal relay module 34, the controller 36, the injection nozzle 48, the washing water tank 42, the pump 41, the pipeline, .

First, the mains lead 10 is a power cable supporting means commonly seen in the vicinity, and has two rows of bridges 12 at the upper end thereof. The brass bars 12 serve to support a plurality of insulators 20 and other components as horizontal bars fixed to the telephone pole 10. [

The insulator 20 in this embodiment supports the jumper wire 14 as a line post insulator. However, any kind of insulator of different kind or design can be applied.

The insulator 20 comprises an insulator main body 22 fixed to the upper portion of the solid wire 12 and a cable holder 23 connected to the upper portion of the insulator main body 22. At the upper end of the insulator main body 22, a wire receiving groove 22a for receiving the jumper wire 14 is formed. The engagement of the jumper wire 14 with the insulator 20 is maintained by connecting the cable holder 23 to the insulator body 22 with the jumper wire 14 inserted in the wire receiving groove 22a.

The shape of the insulator main body 22 is composed of a plurality of disk portions 22b spaced apart from each other in parallel and a connecting portion 22c located between the disk portions integrally with the disk portion 22b. In particular, a fitting groove 22d is formed on the outer circumferential surface of the disk portion 22b. The fitting groove 22d extends along the circumferential direction of the disc portion 22b and receives the insulator pressing band 24 as a groove at which both ends thereof meet.

The insulator pressing band 24 is mounted on a selected one of five disk portions 22b in the figure. However, it can be mounted on all discs as required.

The insulator pressing band 24 surrounds the insulator and resiliently presses it, for example, to prevent the detachment of fragments upon physical breakage of the insulator, and to support the detection part 32. [ The insulator pressing band 24 will be described first with reference to FIG.

5 is a perspective view showing the insulator pressing band 24 and the leakage current detector 30 shown in Fig.

As shown in the figure, the insulator pressing band 24 includes a band body 24a which is a closed curve and fits in the fitting groove 22d of the disk portion 22b, and a supporting body 24b integrally formed on one side of the band body 24a. And a portion 24b. The band body 24a is made of rubber or silicone and is elastically deformable. The band body 24a is filled with the fitting groove 22d while being stretched by the operator. Since the band body 24a is filled with tension, the contracting force of the band body 24a is transmitted to the fitting groove 22d. In other words, the disk portion 22b is fastened to the band body 24a.

Therefore, even if the insulator 20 is cracked due to the use of the insulator 20 for a long period of time, the insulator 20 can keep its shape continuously as long as the band body 24a applies the contracting force It is. Even if the insulator is damaged, it will hold for a while.

The support block portion 24b serves to support the leakage current detector 30 as a portion exposed to the outside of the fitting groove 22d. That is, the leakage current detector 30 is supported on the insulator pressing band 24.

The leakage current detector 30 is composed of a pair of plate springs 31 and a detection part 32 supported at the extending end of each plate spring 31. The leaf spring 31 is a resilient member having a predetermined width and bent at its central portion and each extending to the upper and lower portions of the disc portion 22b with one end of the leaf spring 31 being fixed to the support block portion 24b. Particularly, each plate spring 31 is elastically biased toward the disk portion 22b side, and presses the detection portion 32 in the direction of arrow f in Fig.

The leaf spring 31 is made of a synthetic resin having no elasticity. In some cases, a metal elastic plate (not shown) may be embedded in the inside of the leaf spring 31 to achieve a more elastic force. The shape of the leaf spring 31 can be variously changed as long as the detection portion 32 can be elastically pressed in the direction of arrow f.

The detection part 32 is an electronic part fixed to the extending end of each plate spring 31. [ This senses the flow of the leakage current in a state of being interviewed on the upper and lower surfaces of the disk portion 22b. The detection unit 32 includes a close contact case 32d in the form of a substantially hexahedron, a current sensor 32a fixed in the close contact case 32d, a battery 32b and a communication unit 32c.

The close contact case 32d is inserted into fixing grooves (22e in Fig. 4) separately formed on the upper and lower portions of the disc portion 22b. The fixing method of the close contact case 32d with respect to the fixing groove 22e can be variously applied. For example, the press fitting fixing method may be applied.

The fixing grooves 22e may not be formed in some cases. For example, if the close contact case 32d can be stably fixed to an arbitrary surface of the insulator main body 22, it is not necessary to form the fixing groove 22e and fit the close contact case 32d in the fixing groove. The close contact case 32d can be made of an insulating synthetic resin or rubber.

The current sensor 32a senses a minute current flowing through the surface of the insulator body 22 as an electronic material that is in contact with the surface of the insulator body 22. The current sensing principle of the current sensor 32a may vary as much as possible. The sensed information sensed by the current sensor 32a is delivered to the signal relay module 34 in real time. The signal relay module 34 is wired or wirelessly connected to the detection unit 32 and receives the contents detected by the detection unit 32 and delivers the received contents to the external controller 36.

The battery 32b supplies electric power to the current sensor 32a and the communication unit 32c as a rechargeable battery. For example, it supplies power for driving the current sensor 32a and the communication unit 32c. Particularly, the battery 32b can be charged by the solar power generation unit 70 to be described later. The solar power generation unit 70 generates electric power for driving the agitator device 18 and a part of the electric power generated by the solar power generation unit 70 is transferred to the battery 32b. The charging method of the battery 32b may be a wireless charging method or a wire charging method.

The signal relay module 34 is fixed to the barrel 12 and transmits information received from each insulator 20 to the controller 36. The installation position and number of the signal relaying module 34 can be changed as needed.

On the other hand, the insulator 18 of the present embodiment further includes a wash water supply unit 40 and a pipeline. The wash water supply unit 40 is composed of a wash water tank 42 and a pump 41 and supplies the wash water through the pipeline.

The wash water tank 42 is a water tank for receiving wash water supplied from the outside. 1, the position of the washing water tank 42 can be changed, although the washing water tank 42 is fixed to the telephone main body 10. [ For example, it may be buried in the ground at the bottom of the telephone pole 10, or may be disposed at a point away from the telephone pole 10.

Since the washing water is for washing the surface of the insulator 20, it should be fresh water free from foreign matter. An antifreeze may be added to the wash water, especially during cold weather.

The pump 41 is controlled by the controller 36 and pumps the wash water in the wash water tank 42 and supplies it to the pipeline. The controller 36 may operate based on information received through the signal relaying module 34 or may operate through the administrator terminal 38.

The information received through the signal relaying module 34 is information that a minute current flows through the insulator main body 22. In the case where the surface of the insulator main body 22 is contaminated with dust or contaminants, fine current flows on the surface thereof, so that contamination can be judged based on the presence or absence of a fine current flow.

The controller 36 activates the pump 41 to spray the washing water to the insulator 20 when the controller 36 determines that a current is flowing through the insulator surface through the signal relaying module 34. [ The cleaning of the insulator 20 is automatically implemented.

The controller 36 may be operated manually through the administrator terminal 38. [ The administrator terminal 38 is, for example, a smart phone or a tablet PC. The manager can check the comprehensive state of each electric pole 10 while moving the manager terminal 38 while carrying it, and can operate the controller 36 as needed. For example, to cool the insulator in a chilly period, or to spray chilled water to chase a bird when building a bird house on a barrel 12.

As a result, irrigation water can be injected into the insulator 20 whenever necessary, irrespective of whether it is an irregular periodic period or a current leaked through the insulator.

The pipeline includes a supply pipe 43 fixed to the outer peripheral surface of the electric pole 10 and extending upwardly, a horizontal pipe 44 horizontally piped to the wrought iron 12, 20). ≪ / RTI > The washing water pumped by the pump 41 is supplied to each of the vertical pipes 46 via the supply pipe 43 and the horizontal pipe 44.

In addition, a plurality of injection nozzles 48 are installed in each vertical pipe 46. The injection nozzle 48 injects the washing water supplied through the vertical pipe 46 toward the surrounding insulator 20 to remove foreign matter adhering to the surface of the insulator 20. [

A surveillance camera 50 is installed at the upper end of the vertical pipe 46. The surveillance camera 50 captures the state of the insulator 20 and transmits the photographed contents to the controller 36. The image information transmitted to the controller 36 is processed appropriately and then transmitted to the administrator terminal 38. And it is also possible to directly transmit the shooting information of the surveillance camera 50 to the administrator terminal 38 as needed.

The manager can visually confirm the status of the barrel 12 via the manager terminal 38 on the ground, even if he or she does not get up on the telephone pole.

Meanwhile, a solar power generator 70 is installed at an upper end of the electric pole 10. The solar power generating unit 70 has a pair of solar battery boards 78, and is unfolded to produce electric power during use. The power produced by the solar power generation unit 70 is used to drive the agitator device 18.

The detailed configuration of the solar power generating unit 70 is shown in Figs. 8 and 9. Fig. Fig. 8 shows a state when the solar power generating section 70 is opened and used, and Fig. 9 shows a state when the solar power generating section 70 is not used. For example, when a strong wind is blown, the solar power generating unit 70 is folded to temporarily stop use.

8 and 9, the solar power generator 70 includes a housing 71 having a housing space 71a, a support disk 79, a spring 74, a hinge bracket 76, A rotation plate 75, a solar panel 78, a tension wire 84, and a winding means.

The housing 71 is fixed to the upper end of the electric pole 10 and takes the form of a column extending in the vertical direction. The diameter of the housing 71 is equal to the diameter of the upper end of the electric pole 10. The housing 71 may be formed of concrete, or may be made of FRP or hard plastic.

The accommodation space 71a is a space opened to the upper and side portions of the housing 71 and has an engagement protrusion 71b on its inward surface. The latching jaw 71b is a jaw supporting the lower end of the spring 74. [

The support disk 79 is a plate-shaped member that can be lifted and lowered in the accommodation space 71a, and has a through hole 79a at the center thereof, and moves up and down while maintaining the horizontal position. If necessary, a separate guide means for guiding the lifting and lowering of the support disk 79 may be added.

The spring 74 is provided at a lower portion of the support disk 79 and supports the support disk 79 in an upward direction while the lower end of the spring 74 is caught by the engagement protrusion 71b.

The hinge bracket 76 is a member fixed to the center of the support disk 79 and has a tension wire 84 at its bottom surface. The tension wire 84 is connected to the bottom of the hinge bracket 76 and extends downwardly through the through hole 79a to be connected to the winding means.

The winding means includes a winding pulley 82 for winding a tensioning wire 84 and a motor 81 for driving a winding pulley 82. The motor 81 is controlled via the controller 36 to unwind or unwind the winding pulley 82.

At both ends of the hinge bracket 76, a pivot shaft 77 is provided and a pivot plate 75 is connected to each pivot shaft 77. The pivot plate 75 is rotatable in the direction of the arrow z and the opposite direction while being supported by the pivot shaft 77.

The solar panel 78 is mounted on each of the rotation plates 75. As shown in Fig. 8, the solar panel 78 absorbs sunlight in a deployed state to produce electric power. The power generation mode of the solar panel 78 itself is the same as that of a general solar panel.

The rotation plate 75 and the solar panel 78 maintain the unfolded state as shown in FIG. 8 by the action of the spring 74 and the support disk 79. At this time, the tension wire 84 must also be released.

8, in order to withdraw the solar panel 78 (for any reason), the motor 81 is operated to stretch the tension wire 84 in the direction of the arrow e. When the hinge bracket 76 is lowered as the tension wire 84 is pulled downward, the pivotal plates 75 on both sides extend over the upper end of the housing 71 and are gathered in the direction of the arrow z, It folds in.

The support disk 79 and the hinge bracket 76 compress the spring 74 to descend and the pivoting plate 75 is rotated in the direction of the arrow e as shown in FIG. And is completely inserted into the accommodating space 71a.

9, when the winding pulley 82 is rotated in the opposite direction to release the tension wire 84, the support disk 79 is raised by the action of the spring 74, 71a and is unfolded to become the state shown in Fig. In some cases, a separate elastic member may be provided between the pivot plates 75 to guide the pivoting of the pivot plate 75.

Hereinafter, the same reference numerals as those of the above-mentioned reference numerals denote like members having the same function, and unnecessary repetitive descriptions related thereto will be omitted.

Referring to FIG. 5, it can be seen that the arch-pressing band 60 is filled in the arbitrary disc portion 22b of the plurality of disc portions 22b. The insulator pressing band 60 is a resilient member and is filled in an optional disc portion 22b in a state of being stretched by an operator to press the disc portion 22b. The insulator pressing band 60 can be made of elastic rubber having elasticity.

The insulator pressing band (60) has a band body (61) having a certain thickness and width and a supporting block part (62) integrally formed on the outer surface of the band body (61). The band body 61 protects and presses the disc portion 22b. As in the case of the above-mentioned insulator pressing band 24, even if a crack occurs in the insulator body 22 or even if the insulator detonates at all, it is possible to hold the insulator's fragments to maintain the insulator shape to some extent (before maintenance).

A plurality of ventilation holes 64 are formed in the band body 61. The air vent 64 is a hole through which air passes, and serves as a passage for discharging the heat of the disk portion 22b.

The support block portion 62 serves to support the leakage current detector 30. [ The rear end portion of the leaf spring 31 of the leakage current detector 30 is fixed to the support block portion 62 to support the detection portion 32 while being fixed. The detection unit 32 receives elastic force from the leaf spring 31 and is elastically held in the fixing groove 22e.

As shown in Fig. 7, most of the insulator body 22 may be wrapped with the insulator pressing band 60. Fig. For example, in the case of an insulator applied to a frigid region, the insulator body 22 can be entirely covered because the insulator can easily explode.

7, the plate spring 31 is omitted for installing the detection unit 32. In this case, The detection unit 32 forms a mounting hole (not shown) in the eraser pressing band 60 and fixes it by fitting the mounting hole.
