[

The input unit 410 constituting the control unit 400, the control unit 420 and the motor driving unit 430 are mounted on a single circuit board and constituted by a control module 440, (450).

In the control box 450, a rechargeable battery 460 for supplying power to the control module 440 is installed.

The control module 440 is provided with a charging circuit unit (not shown) for receiving a commercial current flowing through the power distribution line 50 and outputting a charging current for charging the charging battery 460 to charge the charging battery 460 .

Hereinafter, the opening and closing operation of the insulating cover 100 by the power distribution system operating system of the present invention will be described.

The controller 420 outputs a forward mode operation command to the input unit 410 and the motor driving unit 430 drives the driving motor 320 in accordance with an output command of the controller 420 The forward mode driving signal is transmitted.

Accordingly, the driving motor 320 is driven in the forward mode, the hollow motor shaft 321 is rotated in the forward direction, and the right helical female threaded portion 322 formed on the left half of the inner peripheral surface of the hollow motor shaft 321 and the left helical- The left driving bar 330 is advanced in the advancing direction (left direction in the figure) by the screw action of the right-hand screw portion 331 of the driving rod 330, The right operating rod 340 advances in the advancing direction (the right direction in the drawing) by the screw action of the left helical female threaded portion 323 and the left helical threaded portion 341 of the right driving rod 340.

At this time, since the distal end (left end) of the left driving bar 330 is fixed to the free end outer flange 132 of the left insulating cover 100, the free end of the left insulating cover 100 moves to the left, The cylindrical portion 110 of the corrugated pipe shape of the left insulative cover 100 is unfolded to surround and protect the suspending insulator 30 and the connection port 40. The distal end portion (right end portion) The free end of the right side insulated cover 100 moves to the right side since the insulated cover 100 is fixed to the free end outside flange 132 of the insulated cover 100. Accordingly, So that the suspending member 30 and the connection port 40 are surrounded and protected (see a solid line in FIG. 3).

Therefore, the suspension insulator 30 and the connection port 40 are surrounded by the insulation cover 100 made of rubber excellent in insulation, and are protected from snow and sunlight, thereby minimizing the possibility of short-circuiting, electric shock, short-circuiting.

The free end outer flange 132 of the insulating cover 100 is moved in the linear direction by the guide rod 220 and the guide hole 230 in the process of moving the free ends of the left and right insulation covers 100 to the left or right, The operation of the insulating cover 100 is smoothly performed.

In contrast, when the retraction mode is input to the input unit 410, the control unit 420 outputs a retraction mode operation command, and the motor driving unit 430 transmits a retraction mode driving signal to the driving motor 320. [

As a result, the drive motor 320 is driven in the retraction mode, the hollow motor shaft 321 is rotated in the retracting direction, and the free end of the left insulation cover 100 is rotated in the reverse direction to that in the above- The free end of the right side insulated cover 100 is moved in the retreating direction (the left side direction in the drawing), and the movable insulator 30 and the suspending insulator 30, which are surrounded by the insulated cover 100, The connection portion 40 is exposed (see a virtual line mark in Fig. 3).

This retraction mode is necessary when the field worker checks the suspender insulator 30 and the connection part 40 and the field worker operates the input part 410 provided in the control module 440 in the control box 450 .

Therefore, inspections for maintenance of the suspension insulator 30 and the connection port 40) can be made by inserting the insulating cover.

Further, since the drive motor 320 constituting the opening / closing means 300 for opening and closing the insulating cover 100 is mounted in the motor casing 310, the functional failure does not occur due to rain, snow, and wind, Management and management.

The present invention can be improved in addition to such a configuration so as to secure easiness of the installation work while enhancing the insulation of the brass ball 20. [

That is, since the conventional wire rods 20 are made of a metal material, they can not be manufactured in the form of hollow squares but are free from short-circuiting or lightning, even if they have a sufficient insulation structure due to metallic materials.

In addition, since the clamping method using the band type clamp is used, the assembling operation is difficult and inconvenient, and the control box 450 is also very inconvenient because it must be banded using a separate clamp.

Thus, in the present invention, the above-described structure is intact and facilitated by the fixing structure of the bare iron 20 and the control box 450, and the insulation is enhanced, thereby making it possible to more secure distribution system management operation.

To this end, in the present invention, a rectangular fixing groove 500 is formed at a predetermined depth by being formed at the center of the top surface of the electric pole 10.

A rectangular fixing bar 510 is inserted into the rectangular fixing groove 500 and a rectangular block 520 is integrally fixed to the upper end of the rectangular fixing bar 510.

In addition, a through hole 512 is formed in a part of the length of the rectangular fixing bar 510 in the thickness direction.

A through hole 530 is formed in the periphery of the upper end of the electric pole 10 in a radial direction. The through hole 530 is formed to extend across the rectangular fixing groove 500 to communicate with the through hole 530.

Accordingly, when the rectangular fixing bar 510 is inserted into the rectangular fixing groove 500, the through hole 512 and the through hole 530 are aligned with each other.

When the long bolt 540 is inserted through the through hole 512 and the through hole 530 in a state where the through hole 512 and the through hole 530 are aligned with each other and the binding nut 550 is fastened to the exposed end of the long bolt 540, 510 can be firmly fixed without detaching.

In addition, wedge fixing bolt grooves 522 are formed on both sides of the square block 520.

Particularly, the square block 520 including the rectangular fixing bar 510 is a lightweight molding material having durability and formed of a synthetic resin mixture. Therefore, it is light and easy to climb up, and there is no difficulty to install.

The fixed wrought iron 20 'according to the present invention, which is improved from the wrought iron 20 according to the present invention, differs from the above-described metallic material in the shape of a rectangular metal bar, in which a solid body formed of the same synthetic resin mixture as described above, .

The insulating cover 100, the insulating cover supporting means 200, the opening and closing means 300 and the like provided on the fixed wrought iron 20 'are also mounted on the fixed wrought iron 20' And only the assembled structure between the electric pole 10 and the fixed wrought iron 20 'is improved.

To this end, bolts are fixed to both sides of the square block 520 in a state in which a pair of fixed wrought iron 20 'as shown in FIG.

At this time, a pair of the fixed wrought iron pieces 20 'are spaced apart by the gap maintaining bar 600. The gap maintaining bar 600 includes a central locking part 610, And an insertion portion 620 having a smaller diameter than the central locking portion 610.

The fixed wedge 20 'is inserted into the inserting portion 620, and the fixed wedge 20' is not inserted because the central wedge portion 610 has a step.

Here, the length of the central locking part 610 should be smaller than the width of the rectangular block 520 to which the fixed wrought iron 20 'is to be closely attached.

The coil spring 630 is inserted into the inserting portion 620 exposed through each of the fixed wrought iron pieces 20 'and the head-shaped fixing pin 640 is bolted to the end face of the inserting portion 620 .

Thus, one end of the coil spring 630 is fixed to each outer side of the fixed wedge 20 ', and the other end is fixed to the head portion of the head type fixing pin 640 to provide an elastic force.

These structures are arranged so as to be spaced apart in pairs,

Therefore, when the fixed wrought iron 20 'is installed, the fixed wrought iron 20' is held on the square block 520 and the coil spring 630 is pulled in the opposite direction to compress the coiled spring 60 ' Put and put what you pulled.

This is possible because the fixed wedge 20 'is tightly adhered to both sides of the square block 520 by the elastic returning force of the coil spring 630. This is because the length of the central locking portion 610 is rectangular Is less than the width of the block 520.

Thereafter, when the fixed wrought iron 20 'is fastened and fixed to the square block 520 using the fixing bolts BLT, the fixed wrought iron 20' can be assembled easily and conveniently.

Moreover, they are safer because they are molded into a synthetic resin mixture with electrical insulation and durability.

In addition, in the present invention, an installation hole 700 is formed through one of the fixed wrought iron pieces 20 'so as to penetrate upward and downward, and a stopping jaw 710 having a step at a predetermined depth position is formed in the installation hole 700 .

That is, it is understood that the engagement protrusion 710 is formed to have a smaller diameter than the installation hole 700.

A spring SPR is interposed between the latching protrusion 710 and the lower end surface of the head unit 810. The spring SPR is preferably inserted into the fixing rod 800. [

Therefore, due to the spring SPR, the fixing rod 800 can elastically move upward and downward within the mounting hole 700.

A rod thread 820 of 2-3 pitches is formed around the head portion 810 at a position spaced apart from the upper end by a predetermined distance to prevent the fixing rod 800 from being detached and separated. A mounting bore thread 720 of 2-3 pitches is also formed on the inner diameter of the bore 700.

When the fixing rod 800 is mounted, the rod thread 820 is screwed to the mounting boss thread 720 so that the rod thread 820 is routed over the mounting boss thread 720, And is assembled so as to pass over the bore threads 720.

However, since the rod thread 820 is caught by the mounting bore thread 720, the fixing rod 800 can not move upward and downward, (SPR) is positioned so as to have elasticity while being suppressed.

In this state, when the box fastening tool 900 is fastened to the box fastening bolt groove 812 through the ceiling face of the box body 451 (see FIG. 1), the control box 450 is also very complicated, So that it can be fixed and installed easily, conveniently and safely.

Further, the above-mentioned thiocyan copper is added as a copper-based antifouling agent in order to suppress foreign matter adhesion and to enhance moisture resistance, i.e., moisture resistance.

Further, the F-T wax (Fischer-Tropsch Wax) is added for the purpose of controlling the viscosity and increasing the crosslinkability and suppressing the deformation of the coating.

In addition, the sodium silicates are added to improve the binding between the compositions.

In addition, the atactpulse is added for thickening and bulking. However, in the present invention, it is added in order to strengthen the elasticity and increase the heat resistance according to the improvement of the elongation due to the fibrous structure.

The pozzolan is mainly used as a concrete admixture, but it is an artificial pozzolan. In the present invention, natural pozzolans collected from weathered volcanic rocks and volcanic rocks are used to increase acid resistance, corrosion resistance, durability and waterproof property, The particle size is preferably 0.1-0.2 mm.

In addition, the polybutene is added to enhance ultraviolet rays, heat and chemical stability.

In addition, the monoglyceride is added to enhance the anti-foreign material property by promoting emulsification and inhibiting foreign matter from adhering to the surface.

The ethylene glycol monomethyl ether is added to enhance durability by enhancing adhesion and maximizing adhesion.

In addition, sebaceous acid is added to enhance the function of inhibiting foreign body adhesion.

The terbium is added as a rare earth metal belonging to the lanthanide group to enhance abrasion resistance. The alkylene amide is added in order to maintain lubricity and stability, so that the mixing is smoothly performed, and after the mixing, Lt; / RTI >

The polycarbonate resin is a base resin for enhancing abrasion resistance by establishing strong durability and hardness characteristics while ensuring transparency.
