Description

Insulator Linker For Very High Voltage Distribution Line Of Tension Control}

The present invention relates to an aza linker for tension control of a high-voltage transmission line.

In general, insulators are insulators that are fixed on a wrought iron installed in a pole and used to insulate the spiral portions of transmission and distribution lines and simultaneously maintain or support them mechanically.

Such insulators merely have a function of fixing the transmission line, and in order to install the transmission line in the insulator, the middle part is loosely connected so that the middle part sags downward because it is manually pulled by the worker.

Therefore, if the wind blows strongly, the transmission line will flow (rumble), and the ripples generated by the flow of the transmission line will be transmitted directly to the insulator, resulting in damage to the insulator and severely leaving the steel. Falling accidents used to occur frequently.

In particular, since there is no means to inform in advance that deflection or expansion of the processing wire due to temperature changes, such as summer or winter, there is no means for workers to check the state of the processing wire during the summer or winter. There was a problem of excessive time and cost.

In addition, if the connection is separated or broken due to the sagging or expansion of the processing wire due to temperature change, such as in summer or winter, when repairing for this purpose, work must be carried out with a power cut, which is a great inconvenience for generations that need to use electric power. As there is a problem that causes overrun, researches are actively underway to solve such problems.

On the other hand, there is a conventional insulator as described above Patent No. 10-0989444.

Therefore, studies on the fixed insulators that can be easily installed and dismantled without a separate tool when combining the insulators and the completes have been actively conducted.

The present invention has been made to solve the above problems, it can easily respond to the change of the transmission line according to the seasonal change can prevent the transmission line is separated or broken from the insulator, do not use a separate tool It is an object of the present invention to provide an aggregator for tension control of an extra-high voltage transmission line that can be easily installed and dismantled on a support without any need for installation.

When the temperature rises, the power distribution line (L) is limp, so that the force to pull between the power transmission line (L) fixed to each of the insulator (30) acts.

Therefore, when the transmission line L is limp as described above, the spring 50, 50 'mounted on the insulating bars 20, 20' is reversely applied by the force acting on the transmission line L By keeping the tension to maintain a tension state, it can be prevented from being separated from the insulator 30 by excessive deflection of the transmission and distribution line (L).

On the contrary, in winter, the transmission and distribution line L is contracted so that the length of the transmission and distribution line L is shortened. In this case, the insulation bars 20 and 20 'are moved along the guide rail 11 in the contracted direction. At the same time, the springs 50 and 50 'mounted on the insulation bars 20 and 20' are also tensioned together to prevent breakage of the transmission and distribution line L due to shrinkage, and insulator by excessive contraction of the transmission and distribution line L. Departure from 30 can be prevented, and a series of such embodiments are illustrated in FIG. 5B.

In addition, by providing stoppers 12 at both ends of the guide rail 11, even if the insulation bars 20, 20 'are moved to both ends of the guide rail 11 by the transmission and distribution line L, the guide rail 11 Since the movement of the insulation bars 20 and 20 ′ is limited by the stopper 12 installed in the), it is possible to prevent the insulation bars 20 and 20 ′ from being separated from the outside.

In addition, since the insulator 30 installed on the insulation bars 20 and 20 'can be easily installed and released without a fastening means, the operator does not need to carry a separate tool, and the work time is drastically shortened. This has the advantage of being very convenient.

In addition, by interfering with the view of the bird by reflecting the light of the sun through the eradication mechanism 40 installed in the insulator 30, the bird sitting on the transmission line (L) or nesting on the mount 10 There is an advantage that can be prevented.
