Fig. 14 is a photograph showing a shape of a conventional line side metal fitting, Fig. 15 is a view schematically showing a state of a ground side metal fitting, and Fig. 16 is a cross- It is a photograph.

As shown in FIG. 14, the conventional line-side metal fitting includes a horizontal tightening bolt 100-6 and a vertical tightening bolt 100-6 for adjusting the distance between the body 100-1 and the tightening plate 100-8, 100-2, 100-7, a barbell gear 100-5, and horizontal / vertical tightening bolts 100-6 / 100-7. -3) and a vertical tightening ring 100-4.

In order to perform a grounding operation on a conductor (for example, a wire ACSR 480 mm 2) connected to a power facility that has been interrupted, first, the grounding of the grounding- The grounding bracket 30-1 is manually connected to the grounding conductor buried in the ground, the tightening lever 30-2 is turned clockwise by hand to fix the grounding-side metal fitting, The body 100-1 is inserted into the wire ACSR 480 mm 2 with the cutting rod 50 by inserting the first operation ring 40-1 connected to the wire rope 50 into the first operation ring 40 -1 is removed from the body 100-1 and the bent bar 50 is rotated 180 degrees so that the second operation loop 40-2 is inserted into the vertical tightening ring 100-4 when the wire ACSR 480 mm2 is horizontal And when it is in a vertical state, it is inserted into the horizontal tightening ring 100-3 and turned around 18 to 20 times in the clockwise direction to secure the line side bracket to the wire ACSR 480 Mm2 and the cutting rod 50 is removed from the body 100-1, the ground attachment operation is completed.

When the ground is released, the second operation ring 40-2 is inserted into the horizontal / vertical tightening rings 100-3 / 100-4 of the line side metal fittings and the horizontal / vertical tightening bolts 100-6 / 100-7 The second operation ring 40-2 is pulled out of the body 100-1 and the cut rods 50 are rotated 180 degrees in the counterclockwise direction by turning the half- The first operation ring 40-1 is inserted into the connection wire hooking connection ring 100-2 so that the body 100-1 is pushed up by the connection bar 50 and separated from the wire ACSR 480 mm2, The grounding demolition work is completed when the fixed support 30-1 is manually separated from the grounding conductor buried in the ground by turning the tightening lever 30-2 of the grounding metal fitting in the counterclockwise direction by hand.

However, according to the conventional line side fitting to which the ground is attached or removed as described above, there is a problem in the grounding process and the grounding state according to whether the type of the grounding conductor is a wire or a conductor.

First, in case that the conductor to be grounded is an electric wire, in order to attach the line side metal fitting to the electric wire, it is necessary to attach a wire to the wire which is far from the grounding worker as much as the working distance (insulation distance between the grounding conductor and the worker, The body 100-1 is passed through the first operation ring 40-1 of the insulation bar, the first operation ring 40-1 is removed, the insulation bar 50 is rotated 180 degrees, It is necessary to turn the horizontal / vertical tightening ring 100-3 / 100-4 by about 18 to 20 times with the main body 40-2 so that the body 100-1 is fixed to the electric wire and the grounding work is completed, , It is necessary to connect 2 ~ 3 stages of the bent bar with the length of 1M and the weight of 1.5kg so that the length of the bar is 4 ~ 6M and the weight is 3 ~ 4.5kg. It is difficult to attach the rail side bracket to the electric wire, and horizontal / vertical tightening bolts (100-6 / 100-7) The process of inserting the second operation ring 40-2 inserted into the ring 100-3 / 100-4 is also difficult and it is difficult to insert the second operation ring 40-2 into the body 100-1 during the rotation of the horizontal / vertical tightening ring 100-3 / The second operation ring 40-2 is not tightened to the horizontal / vertical tightening rings 100-3 / 100-4 and loosened so that the body 100-1 is not firmly fixed to the electric wire, Causing a power failure.

In addition, when removing the rail side bracket from the wire, the rail side bracket is dropped to the ground due to the working conditions such as the weight and length of the rope, wind strength, and the limit of the worker's strength. The horizontal / vertical tightening bolts (100-6 / 100-7) projecting outwardly like horns due to the impact at this time are easily curved and can not be reused unless they are straightened. Therefore, in order to reuse the rail side metal fittings, And the threads of the horizontal / vertical tightening bolts 100-6 / 100-7 and the barbell gear 100-5 are worn out when the line fittings are used several times, And the fastening plate 100-8, which is a part where the line side metal fittings come into close contact with the electric wire, is often detached or lost, so that the time required for the grounding work is excessively long or delayed. do.

In addition, when the conductor to be grounded is of the same type, there are problems with the method and problem of attaching or removing the line side bracket to the same base, as well as the following problems.

In other words, since the distance between the end of the body 100-1 of the rail side metal fitting and the tightening plate 100-8 is only 60 mm at maximum, the width of the pedestal 40 mm is longer, 100-3, and 100-4 in order to fix (ground) the line-side metal fittings to the base in this incomplete insertion state. In this incomplete insertion state, the horizontal / vertical tightening rings 100-3 / The body 100-1 can not be detached from the base and can not be fixed (grounded) to the base. Therefore, in order to hold the ground, an incomplete grounding state in which the body 100-1 is made to extend over the pedestal in a state in which the tightening of the horizontal / vertical tightening rings 100-3 / 100-4 is omitted, It is inevitable to cause a safety accident or a power outage failure due to residual charging current or induction voltage.

A latch type grounding tool according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 13 attached hereto. FIG. 1 is a perspective view of a grounding type grounding apparatus according to a first embodiment of the present invention. And a ground wire that interconnects the line-side metal fitting and the ground-side metal fitting.

The line side metal fitting 10 according to the first embodiment of the present invention includes a conductor connecting clamp 1 fixed to the grounding conductor D and a conductor connecting clamp 1 inserted into the inner side of the conductor connecting clamp 1 to be connected to the hinge axis 3 A guide member 3 rotatably coupled via a spring 1 and resiliently supported by a spring 2 and a rotary shaft 4-1 inserted in an inner surface of the other side of the conductor connection clamp 1, And the latching piece 4 is held so as to prevent the torsion of the spring 2 from being released when the grounding conductor D is grounded and the guide member is loosened when the grounding is released, And a rope connecting ring formed on the outer surface of the conductor connecting clamp so as to be coupled with the connecting rope.

The conductor connection clamp 1 is formed so as to be curved at a predetermined curvature so that one side thereof is opened and the bent inner surface thereof surrounds a part of the outer surface of the ground conductor D in close contact.

The conductor connecting clamp 1 and the rope connecting ring 6 constitute a conductor connecting clamp 60. The latching piece 4 and the rotating shaft 4-1 constitute a latching portion 70, The spring 2, the hinge shaft 3-1, and the guide member 3 constitute a spring portion 80.

At this time, the conductor connection clamp 1 may be formed with a connection wire connection ring 5 on one side of the ground wire 20 to which the ground wire 20 is connected, So that the ground bar 50 to which the metal fitting 40 is coupled can be used together.

Hereinafter, the process of attaching and removing the line side metal fitting 10 to and from the ground conductor D will be described. The grounding conductor D according to the first embodiment is described as having a line ACSR of 480 mm 2 and a diameter of 100 × 6t However, the present invention is not limited to this.

10 shows the latching type grounding tool 4 in a normally stored state as shown by the dotted line inside the curved surface of the conductor connecting clamp 1, The end of the member 3 opposite to the portion connected to the hinge shaft 3-1 is positioned on the rotary shaft 4-1 because the torsion of the spring 2 is in a released state. In order to hold the ground using the line-side metal fitting 10 of the present invention in the above-described state, the spring 2 must first be torsed to the state shown in FIG. In order to do so, in FIG. 10, which is a normal storage state diagram, the longer side of the conductor connecting clamp 1 with the cut-off wire connecting ring 5 on the left hand and the opposite side of the cut- The right and left operating grips 90-1 and 90-2 of the operating driver 90 shown in Fig. 1) is hooked on a manipulation ring of a spring (2) shaped like a "C" shaped on the guide member (3) and one end of the driver body (90-2) is connected to the short end of the conductor connection clamp The guide member 3 comes along with the spring 2 on the end of the conductor connecting clamp 1 having a shorter length and at the same time, as shown in Fig. 10 (a), when the handle 90-3 is pushed to the outside of the worker, (1) The latching legs (4), indicated by the dotted lines on the curved surface, And rotated in the direction to latch the guide member 3, whereby changes to the state of the normal storage conditions of 10 the ground work readiness FIG.

2, the grounding wire 20 is connected to the connecting bolt hole of the grounding wire 20 pierced from the long side to the short side of the conductor connecting clamp 1 at the bottom of the wire connecting rod 5 in Fig.

Meanwhile, as described above, the grounding conductor D is generally installed at a height of 4 to 5M or more from the grounding worker to the ground. In order to carry out the grounding work, the operator needs a separate work- An operating metal fitting 40 integral with the annual rods 50 is also necessary. For reference, the bent bar 50 referred to in the electric equipment maintenance work site also means the entirety shown in FIG. 2, the conductor connecting clamp 1 of the line side metal fitting 10 of Fig. 2 is inserted into the circular arc shaped connecting ring 5 of Fig. 2, (D) wire ACSR 480 mm < 2 > The above is described in more detail as follows.

In FIG. 5, the first operation ring 40-1 integrated with the bent bar 50 is inserted into the bent bar connecting ring 5, and then the conductor connecting clamp 1 is connected to the wire ACSR 480 mm 2 by an insulating bar.

Then, the first operation ring 40-1 is removed from the cutoff connection ring 5 and the cutoff bar 50 is rotated 180 degrees so as to connect the second operation hook 40-2 to the cutoff connection ring 5, by pulling the bending rod 50 once vertically downward, the wire side bracket 10 of the present invention as shown in Fig. 7 firmly attaches to the wire ACSR 480 mm 2, which is the ground conductor D .

That is, when the bent bar 50 is pulled downward once as shown in FIG. 6, the bent bar connecting link 5 acts downward and the force of the wire ACSR 480 mm 2 acts upward. 10, the latch is released and the guide member 3 is moved upward in the clockwise direction due to the restoring force of the spring 2. As a result, And the lower end of the wire ACSR 480 mm 2 is supported, and the conductor connecting clamp 1 supports the upper side of the wire ACSR 480 mm 2, so that the wire side metal fitting 10 of the present invention is fixed to the wire ACSR 480 mm 2 as shown in FIG. 7 .

On the other hand, in order to remove the line side metal fitting 10 fixed to the wire ACSR 480 mm 2 from the wire ACSR 480 mm 2 as shown in FIG. 7, the first operation ring 40 - The wire side bracket 10 of the present invention is removed from the wire ACSR 480 mm 2 as the ground conductor D by pushing the bent-apart bar 50 upward vertically once in this state.

That is, when the bent bar 50 is pushed upward one time as shown in FIG. 8, the bent bar connecting link 5 acts upward and the force of the wire ACSR 480 mm 2 acts downward. The guide member 3 supporting the lower side of the wire ACSR 480 mm 2 is pushed downward as shown in Fig. 8 and the wire ACSR 480 mm 2 is pulled downward as shown in Fig. It is removed to the lower opening and the demolition work is completed.

When the demolition work is carried out, the latching legs (4) are placed on the upper side of the ACSR 480 mm of the wire, and when the ACSR 480 mm 2 wire completely deviates from the conductor connecting clamp (1) toward the opening of the conductor connecting clamp 10 by the guide member 3 to be restored to the position shown in Fig. Accordingly, the appearance of the latch type grounding tool of the present invention in which the demolition work is completed is shown in Fig. 10, which is a shape of a normally stored state.

Hereinafter, the ground mounting and demounting method and operation principle of the latch type grounding tool of the present invention with respect to all the grounded conductors D are the same as those described above.

As in the case of the wire ACSR 480 mm < 2 > in the case where the grounding conductor D is of the same length (100 x 6 t) as shown in the photograph of Fig. 9, the grounding state is very good and firm. 7, the wire ACSR 480 mm 2 is fixed to the curved surface of the conductor connecting clamp 1 when the grounding conductor D is the wire ACSR 480 mm 2, whereas the conductor connecting clamp 1) is contacted with a surface having a width of 100 mm, and a surface having a width of 6t is brought into contact with the curved surface of the conductor connection clamp (1), so that the grounding area is wide and stable and stable and completely grounded It is applicable to the grounding conductor (D).

As a result, the latch type grounding tool of the present invention has a configuration in which the second operation ring 40-2 is inserted into the connection rod 5 in all the types of ground conductors D and pulled once in the vertical downward direction, The first operation ring 40-1 is inserted into the insulation bar connection ring 5 and is pushed vertically upward one time so that the ground can be dismantled. As a result, it is possible to attach and demount the ground by one operation, It is very simple and easy to use, which reduces labor costs due to safety accidents and shortens grounding work time, and increases stable power supply capability and supply and demand. It should be understood, however, that the specific terminology used herein is for the purpose of describing the present invention and, therefore, may be used interchangeably in the field of the art. Instead of the actuating driver 90, It is also possible to torsion the spring by using a finger or stop.

Meanwhile, unlike the grounding work of a substation or a power distribution facility that performs grounding work on the ground as described above, the grounding work of a power transmission facility that grounds or demolishes grounding to a steel tower in the past has a problem in that, Since the ACSR 480 mm2 is located at the bottom of the worker 4 ~ 5M, it is more difficult and difficult to untie the ground, causing safety accidents and delaying work time.

Thus, the present invention has one or more rope connection rings 6 provided outside the curved surface of the conductor connection clamp 1 to increase the convenience and efficiency of the removal work while solving the conventional problems to increase safety.

The plurality of rope connecting rings 6 may be formed along the longitudinal direction on the bent outer surface of the other side opposite to the opened side of the conductor connecting clamp 1, but the rope connecting ring 6 according to the first embodiment ) Is formed on the outer side of the curved surface of the conductor connecting clamp 1. [

Here, as shown in FIGS. 12 and 13, a connecting rope 7 made of a material such as nylon, which is light and freely bendable and can not be easily broken, is connected to the rope connecting ring 6.

The rope connecting ring 6 and the connecting rope 7 are connected to a ground line (not shown) coupled to one end of the conductor connecting clamp 1 while the conductor connecting clamp 1 is engaged with the ground conductor D The conductor connecting clamp 1 which is hooked on the ground conductor D when the connecting rope 7 is pulled toward the worker during the ground breaking operation can be fixed to the steel tower so as not to flow by the wind etc., So that it can be easily detached from the grounding conductor (D) by being rotated along the outer surface of the grounding conductor (D) through the rope connecting ring (6).

For this purpose, the position at which the rope connecting ring 6 is formed is a position at which the conductor connecting clamp 1 is located at a position midway between the curved inner side center of the conductor connecting clamp 1 and the curved outer side center of the curved surface of the conductor connecting clamp 1, It is preferable that the length of each of the light-shielding portions is formed within a range of 45 degrees in both the shorter side and the longer side.

The reason for this is that the maximum amount of rotation of the conductor connection clamp 1 that rotates through the rope connection ring 6 when the connection rope 7 is pulled out is such that the rope connection ring 6 is in a straight line The conductor connecting clamp 1 rotated through the rope connecting ring 6 and the connecting rope 7 is positioned so as to be closer to the grounding conductor D as the one opened side thereof approaches the opposite side of the worker towing the tower, As shown in FIG.

The connecting rope 7 is attached to the outer surface of the conductor connecting clamp 1 such that the rope connecting ring 6 is formed on the outer surface of the conductor connecting clamp 1 while the grounding wire 20 is fixed to the steel tower. So that the support groove 8 can be formed. This support groove 8 allows the conductor connecting clamp 1 fixed to the steel tower through the connecting rope 7 and the grounding line 20 to remain firmly fixed without being arbitrarily moved during the grounding operation, So that the conductor connecting clamp 1 and the conductor to be grounded D are separated more quickly and easily by allowing the connecting rope 7 to move along the supporting groove 8 when pulled toward the operator.

The conductor connecting clamp 1 is further provided with the rope connecting ring 6, the connecting rope 7 and the supporting groove 8 so that the conductor connecting clamp 1 and the ground connecting wire 1, The conductor connecting clamp 1 and the grounding wire 20 are quickly moved from the grounding conductor D and the steel tower to each other when the grounding demolition is carried out after completion of the operation while allowing the grounding wire 20 to be stably grounded in a state of being fixed to the steel tower It can be easily separated (removed).

Accordingly, since it is unnecessary to use the cutting rods 50 having a length of 2 to 3 stages as in the prior art, it is possible to prevent a safety accident that may occur when the cutting rods 50 fall to the ground, There is an effect to be improved.

In addition, since the procedure of inserting and separating the operating metal fitting 40 into the metal-insulated connecting rod 5 by using the metal-insulated rod 50 is omitted, the convenience and efficiency of the grounding operation and the ground removing operation are increased, The labor cost can be reduced by shortening the time required.
