では架線工法としてその主流を占めるに到うている。[Prior Art] The prefabricated overhead line construction method, which was proposed by the applicant early on as a labor-saving method for overhead transmission lines, has been used to increase the size and ultra-high voltage of electric wires in response to the subsequent demand for higher capacity transmission lines. Due to changes in the overhead line environment, such as increased multi-conductor lengths and longer spans due to the demand for overhead lines, its advantages have been reconsidered, and today it has become the mainstream overhead line construction method.

となど大きな特徴点があり、人的また時間的省力化効果
はきわめて大きい。This prefabricated overhead wire construction method involves precisely measuring the span length of the tower where the overhead wire is to be installed, calculating the length of the wire that will be wired with a predetermined slack between the five spans, and then The wire is cut to 11 lengths on the ground, and the wire is extended by attaching tie clamps on both ends that can pass through the metal wheels beforehand, and the overhead line work is completed by connecting the tie clamps to the steel tower girders. . It has major features such as crimping of the retaining rungs by stable work on the ground instead of high up on steel towers with poor footing as in conventional construction methods, and the ability to omit the tension work to set the slackness. , the effect of saving manpower and time is extremely large.
しかし、上記のようなすぐれた長所を有するプレハブ架
線工法にも問題点がないわ番フではない。However, the prefabricated overhead wire construction method, which has the above-mentioned advantages, is not without its problems.

は早くより開発され、その構造は例えば第７図に示すよ
うな組成よりなる。One such problem is that the detention flag, which has not been previously attached on the ground, must be passed through the metal wheel as it is. Such a retaining clamp that can pass through the metal wheel was developed earlier, and its structure has a composition as shown in FIG. 7, for example.

ゲット川ボルト孔２−ａ。That is, the retaining clamp is divided into the clamp body 2' and the shunter target (not shown), and the jumper socket is not attached during wire extension, and only the clamp body 2- is attached to the end of the SMI as shown in Figure 7. In order to protect these wire ends, a split wire 10 is applied to the outer periphery, and if it is a drawing wire or simultaneous drawing of multiple spans, the split wire 11 is connected and taken out, and then the wire is transferred to the metal wheel as it is. The wire is extended while passing over the top, and when it reaches the designated steel tower, the protector 6- is removed and the clamp body 2- is connected to the resistor chain, and finally the jumper socket is assembled and the bolt hole 2 -a.

もがなり大径がっ長尺なものとなる。[Problems to be Solved by the Invention] As already explained, as power transmission lines have become increasingly high-voltage in recent years, the detention clamps used have also become extremely large, and when a protector is attached to them, the wire extension The end itself also flexes and becomes large in diameter and long.

が、上記のような急激な変動の場合には、延線中の電線
の地上高をコンｌ−ロールし切れず、延線下の建造物な
どに電線が接触し、双方に損害を与えるおそれかある。When passing such a long and highly rigid wire end over the metal wheel 10, the clamp portion having 10 ticks is first caught on the metal wheel 10, as shown in FIG. Get on top of the car and don't give up. It is necessary to add a large amount of tension to force it to ride on the ground, but
Due to such excessive tension, the metal wheel 1o is damaged as shown in Figure 6.
If you force it to ride on the metal wheel, the clamp part will rapidly slide while it rides on the metal wheel and suddenly roll down from the metal wheel. At this time, the previously excessive tension is released all at once, the wire tension decreases all at once, the wire tumbles in, and the wire sag increases instantaneously. When passing the gold wheel, great care is taken to minimize the above phenomenon, but in the case of sudden fluctuations such as the one described above, it is necessary to adjust the ground height of the electric wire while it is being extended. If the L-roll is not completed completely, the wire may come into contact with the building under the wire, causing damage to both parties.
また、上記延線端の走り込みの際に電線１が局部的に曲

特性に悪影響を与えるおそれもある。Further, when the wire end is run in, the electric wire 1 may be locally bent, deforming the outer layer of the aluminum wire, and adversely affecting the characteristics of the electric wire thereafter.

ていた。In addition, in the case of a completely prefabricated construction method in which the wires are measured at the factory, a retaining clamp is crimped on both ends, the wire is wrapped in a drum, and then shipped to the site.When the retaining clamp becomes large, it is necessary to store and fix it in the drum. The diameter of the flange has to be increased, which increases the cost of modifying the drum and transporting it, which increases costs. It was causing harm.

＼の要請が高まっている。Furthermore, even if a large amount of labor is saved by prefabricating the overhead wires, installing the jumper wires using the conventional method would require a certain amount of manpower and time, so even the jumpers should be prefabricated. Demand for prefabricated jumpanos is increasing.

要となり、プレハブ化しても実１ｌＰｊとびなり合致す
るまでに至っていないのが現状である。However, the calculation formula for jumper wires is cumbersome and requires a calculation formula that includes all conditions such as the bending of the support chain, weight, the tension shape of the socket part, and the catenary angle for the tension at the time of overhead wire, so prefabricated. However, the current situation is that it has not yet reached the point where the actual 1lPj matches.

It is intended to provide a prefabricated jumper for use in conjunction with the 10 Tector as well as for attachment to said retaining clamp.

が可能となる。] The restraining clamp is not formed by one rigid body as in the past, but is divided into a plurality of short clamps, and these plurality of short clamps are attached to the electric wire at a distance from each other. Instead of being attached to the entire retaining clamp in two parts as in the past, it is made up of a plurality of piece pieces, and these piece pieces are attached with a small gap between the short clamps. As a result, it is possible to provide flexibility that allows the metal wheel to easily conform to the wheel, and to prevent the occurrence of sudden tension fluctuations when passing the metal wheel.

すればよい。The retaining crank 1, especially the aluminum clamp that serves as a conductive member, must have an effective cross-sectional area commensurate with the current carrying capacity of the power transmission line, so the length of the aluminum clamp is approximately determined by the current carrying capacity. In a large-capacity power transmission system, the length is inevitably long. In the present invention, the elongated aluminum clamp is not constructed from a single tough body;
As shown in a), it is divided into a plurality of short aluminum clamps 2.2 and attached to the electric wire 1 with an appropriate distance between M as shown in the figure. On the other hand, a steel clamp 2a is crimped to the connecting portion of the electric wire 1 to the hook chain as in the conventional example, and the short aluminum clamp 2 is attached thereon. This completes the formation of the clamp body. The figure shows an example in which the short aluminum clamp 2 is attached by the crimping method, but it goes without saying that it is possible to select as appropriate, such as crimping or bolting, and the cross-sectional shape can also be hexagonal, round, etc. You can select it according to your needs.

As shown in the figure, it is composed of a large number of pieces 61.degree. 61 having an outer diameter approximately the same as that of the aluminum clamp 2. piece 6
1 and 61 are attached to the electric wire 1 between a plurality of short aluminum clamps 2.2, or the attachment mode is such that they are not brought into close contact with each other but have a small gap 62.62 as shown in FIG. and install it. By providing such a small gap 62.62,
10 Demonstration When passing the gold wheel, due to its flexibility, it can bend to fit the curvature of the wheel of the gold wheel, so it is difficult to force the gold wheel to pass as in the conventional example described above. There is no need to apply excessive tension, and therefore the tension fluctuation when passing through the safe is small, and there is no risk of running into the wire and instantly increasing the slack of the wire as in the conventional example, so it is possible to achieve extremely stable extension. lines can be implemented.

り締付は固定すればよい。In the present invention, since the clamp main body is divided into a plurality of short aluminum clamps 2.2, a mechanism as shown in FIG. 1 is used to connect the jumper wires to the short aluminum clamps 2.2. That is, as shown in the side view in FIG. 1(c), the revis-type current collector terminals 3.3 are attached to each short aluminum clamp 2.2 as indicated by the arrows in the figure. ! Since the electrical terminal 3 has an insertion groove 3b as shown in field e of the same figure, the terminal 3 has an insertion groove 3b.

。[Effects of the Invention] As described above, according to the present invention, since the regular body at the end of the wire can be configured to be short, the wire can pass through the safe extremely smoothly, and the wire tension can be kept almost constant. It is possible to easily manage and control the height of the electric wire above the ground while the line is being extended. In addition to eliminating the risk of unexpected accidents occurring at times, it also provides a damper effect after the overhead line is completed, eliminating the need to install a damper.Furthermore, it is also possible to pre-crimp the retaining clamp and wrap it in a drum. Their ambition is highly commendable, as they have made the upper jumper wires prefabricated, allowing the advantages of the prefabricated overhead wire construction method to be brought to bear even on the upper floors.
