Description

Cable sleeve device{SLEEVE DEVICE FOR CABLE}

The present invention relates to a cable sleeve device, and more specifically, to a cable sleeve device that can automatically collect, fix, and connect the open strands of a jumper wire even if the strands are unraveled.

In general, the large power generated from a power plant is transmitted to each substation as high-voltage power through transmission lines such as transmission towers, and then the substation transforms the transmitted power and supplies it to each region through electric cables so that each customer can use it. .

In addition, power supply to general consumers is supplied through electric poles. At this time, the electric wire cables from each electric pole are of two-wire and three-wire types depending on the distribution line, and these electric wire cables are connected using jumper wires. .

Meanwhile, in modern society, the demand for electricity is rapidly increasing, and the demand for power quality is gradually increasing. Accordingly, the uninterruptible distribution method, which allows construction to be carried out without cutting off power during work to reduce work outages and supply quality power during construction for new construction and maintenance of distribution lines, is mainly adopted and work is being carried out. .

This conventional uninterruptible distribution method using extra-high voltage distribution lines uses an uninterruptible temporary transmission method using bypass jumper cables for live wires, construction switches, uninterruptible transformers, bypass cables, etc.

Recently, as the risks of the direct live wire method have emerged, the ordering company, Korea Electric Power Corporation, abolished the direct live wire method in 2017 and introduced an uninterrupted power distribution method using the indirect live wire method.

At this time, unlike the previous direct live wire method, in which a live wire engineer wears protective gear and directly touches the extra-high voltage of a live wire while working, the indirect live wire method uses insulation for a live wire about 15m to 2m long to ensure a safety distance. This is a live wire construction method that uses insulating sticks to carry out work without directly contacting live extra-high voltage distribution lines.

Meanwhile, referring to Figure 1, a structure supporting the jumper wire 9 is posted. Basically, each distribution line (3) is connected to the support member (2) of the electric pole (1) by a suspension mechanism (3a), and a polymer insulator (4) is installed to prevent electricity from flowing between the distribution line (3) and the support member (2). ) is placed between the distribution line (3) and the support ring (2).

And a branch (5) is disposed on the distribution line (3), and is connected to a jumper wire (9) connecting the distribution lines (3) on both sides through the branch (5).

Normally, the jumper wire (9) is constructed downward, but at this time, the jumper wire (9) is stretched toward the ground due to gravity.

When performing an uninterruptible power distribution method by applying an indirect live wire method to such a jumper wire (9), the jumper wire must be cut, the covering of the jumper wire must be removed, and then the stranded wires with the wire wound multiple times inside must be interconnected.

Referring to FIG. 2, when the jumper wire 9 is peeled off and the stranded wire 9a inside is relatively intact and wound evenly, the stranded wire 9a is well inserted into the sleeve 7; The jumper wires (9) on both sides that were cut can be fixed and connected to each other.

However, referring to FIG. 3, if the stranded wire (9a) is widened for some reason after removing the covering of the jumper wire (9), it is not properly inserted into the sleeve (7).

In this case, the worker must rewind the stranded wire (9a) by hand and push it in with force. However, if the thickness of the stranded wire (9a) is thick, not only does it not wind well, but the worker uses excessive force, which increases work fatigue. there is.

Referring to Figures 4 to 7, the cable sleeve device 10 of the present invention may include a sleeve body 50, a first inlet 51, a second inlet 53, and a twist correction means 70.

The sleeve body 50 may have an overall cylindrical shape, and a through hole 55 may be formed therein. The jumper wire 9 has a generally circular cross-section, and the stranded wire 9a disposed inside the sheath of the jumper wire 9 is also wound in the circumferential direction to form a generally circular cross-section. Therefore, the sleeve body 50 is implemented in a cylindrical shape so that the stranded wire 9a of the jumper wire 9 can be easily inserted.

The first inlet 51 is formed at one end of the sleeve body 50, and a stranded wire 9a of one jumper wire 9 can be inserted. The second inlet 53 is formed at the other end of the sleeve body 50, and a stranded wire 9a of another jumper wire 9 can be inserted.

The strand correction means 70 is formed on the sleeve body 50, collects the strands 9a of the jumper wire 9 inserted into the first and second inlets 51, 53, and is located inside the through hole 55. It can be inserted smoothly.

This strand correction means 70 may include a first extension part 20, a second extension part 30, and a center fixing part 40.

The first extension 20 is formed between the center fixing part 40 and the first inlet 51 inside the through hole 55, and extends from the center fixing part 40 to the first inlet 51. The cross-sectional area may be gradually expanded.

The second expansion part 30 is formed between the center fixing part 40 and the second inlet 53 inside the through hole 55, and extends from the center fixing part 40 to the second inlet 53. The cross-sectional area may be gradually expanded.

The center fixing part 40 is disposed in the center of the through hole 55 and may be formed in a size corresponding to the size of the stranded wire 9a of the jumper wire 9. This secures the outer circumference of the stranded wire (9a) in the center fixing part (40) to secure the stranded wires (9a) of the jumper wire (9) inserted on both sides and firmly connects the outer circumference of the stranded wire (9a) to each other. The inner circumference size of the center fixing part 40 is set to a size corresponding to .

Referring to FIG. 4, a state in which a jumper wire (9) with the stranded wire (9a) spread apart is being inserted into the cable sleeve device (10) of the present invention is shown.

In the cable sleeve device 10 of the present invention, a center fixing part 40 having an inner circumference size corresponding to the outer circumference size of the stranded wire 9a is disposed in the central part, and the center fixing part 40 is gradually disposed on both sides of the center fixing part 40. First and second expansion parts 20 and 30 of which the cross-sectional area increases are disposed.

Accordingly, it can be confirmed that the first and second inlets 51 and 53 are formed larger than the widened strand 9a due to the first and second expansion parts 20 and 30.

Next, referring to FIG. 5, a state in which the open stranded wire 9a is inserted into the first and second inlets 51 and 53 is shown. Because the size of the first and second inlets 51 and 53 can accommodate the widened wire 9a due to the first and second expansion parts 20 and 30, the widened wire 9a can be used in the first and second expanded parts ( 20,30) can be easily inserted into the interior.

Next, referring to FIG. 6, the open stranded wire 9a is inserted deep into the through hole 55 along the first and second extensions 20 and 30. At this time, the cross-sectional area of the first and second expansion parts (20, 30) gradually decreases as it moves toward the center fixing part (40), so the more deeply the ends of the widened strand (9a) are inserted, the smaller the cross-sectional area of the first and second expansion parts (20, 30) become. It comes in contact with the inner wall and collects.

And when the center fixing part 40 is inserted, as described above, the center fixing part 40 has an inner circumference corresponding to the size of the outer circumference of the stranded wire 9a, so the stranded wire 9a is connected to the center fixing part 40. ), the widened strands 9a are naturally brought together.

Therefore, as shown in FIG. 6, the open strands (9a) are gathered together to form a strand (9a) of one jumper wire (9) and a strand (9a) of the other jumper wire (9) inside the center fixing part (40). are fixed and connected to each other.

Figure 7 is an external representation of the state in which a pair of jumper wires 9 inserted into the cable sleeve device 10 of the present invention are stably fixed and connected.

That is, as shown in FIG. 6, when the stranded wire 9a of a pair of jumper wires 9 is fixed and connected inside the cable sleeve device 10, it looks the same as shown in FIG. 7 when viewed from the outside.

Through the above-described structure, the cable sleeve device 10 of the present invention can automatically collect, fix, and connect the open strands 9a of the jumper wire 9 even if the strands 9a are unwound and widened. Through this, the work speed of the indirect live wire method can be increased, and there is a technical feature that can reduce the excessive workload of workers.

The above merely shows a specific embodiment of the cable sleeve device.

Therefore, we wish to make it clear that those skilled in the art can easily understand that the present invention can be substituted and modified in various forms without departing from the spirit of the present invention as set forth in the claims below. do.
