Description

Insulation cover for live wire operation on power line

The present invention relates to an insulation cover for live wire work on a distribution line, and more particularly, a connection portion of a cable and an insulator constituting a distribution line can be covered in a one-touch manner without a separate fastening member and fastening operation, and is separated into a semicircle shape, Since it can be combined in a cylindrical shape, it is installed to wrap the cable, and when separated from the cable, it is separated into a semicircle so that it can be easily removed. When the first case and the second case are separated, the first case is maintained in a cylindrical shape. 2 It relates to an insulation cover for live wire work on a distribution line that can be easily separated from a cable without separate work while the detachable part is released by the operation of the interlocking operation part.

In general, maintenance work on high-voltage or extra-high voltage (23kV) distribution lines maintains the stability of the power supply and minimizes power outages to improve the reliability of power supply to power consumers. desirable.

In order to increase the reliability of power supply as described above, work must be performed in a state where the voltage is alive, that is, in an uninterruptible live wire state, and most of the current work is performed in such a live wire state.

The live wire work of the distribution line is divided into two types, namely, direct live wire work and indirect live wire work.

In the case of indirect live wire work, the work is performed using a tool called a hot stick. This indirect live wire work is a work using a tool, which has safety but takes a lot of work time.

In addition, in the case of direct live wire work, an operator wears insulating gloves and contacts a special high-voltage wire with a voltage of 22.9kV to perform the work. The work time is short, but there is a very high risk. There have been a number of human damages.

However, because of the advantage of requiring less work time, most live wire works are in direct live wire work, so there is a possibility that the problem of personal injury may continue to occur, so a countermeasure is urgently needed.

More specifically, the connection point of the power line on the distribution line is composed of an insulated wire, a human clamp, a human clamp cover, and an insulator, and is connected to a support (electric pole). The human clamp cover that connects the insulator and the wire is covered with a human clamp cover, so that the charging part of the connection point can be insulated and used. This can be done under the premise that there is no artificial approach such as live work.

Therefore, during live wire work, an insulating cover for live wire work with sufficient insulation properties and excellent mechanical strength must be provided, since access to workers or equipment for work is made at any time.

Insulation cover according to the prior art, in order to protect the charging part (connection point) connected to the insulated wire, the insulating cover may be fixed to the charging part by covering the insulating cover for live wire work on the overhead distribution line from the top of the charging part to the bottom.

Therefore, the insulation cover is stably formed in the live part without damage even under the influence of wind or electric wire vibration.

The live part where the insulation cover is to be formed consists of human clamps and suspension insulators, one end of the human clamp is connected to the insulated wire, the other end of the human clamp is connected to one end of the suspension insulator, and the other end of the suspension insulator is connected to the socket eye and the clasp. It forms a structure that connects to the wancheol of the telegraph pole.

There is Patent Document 1 as an insulating cover according to the prior art. The insulation cover according to Patent Document 1 has a shape size sequentially corresponding to a suspension insulator and an insulator or an insulated wire, an insulator, and a suspension insulator, but the size of the human clamp cover to cover the human clamp cover protecting the human clamp When the body cover and the body cover, which are integrated in a sequential shape and size in reflection, are formed by covering the connection points, they are composed of locking rings that fix both sides of the body cover, and only perform a function of covering the charging part.

Therefore, when the live wire working device collides, the insulating cover may be broken and perforated, and thus the function as the insulating cover may not be performed, and the live wire working device may eventually contact the live part, resulting in a personal accident due to conduction.

In addition, when the insulation cover is damaged or damaged, since the insulation cover has an integral structure, the entire insulation cover must be replaced, resulting in high maintenance costs.

In order to solve the above problems, an insulation cover for live work on distribution lines was developed, and the insulation cover according to the prior art wraps and protects the first cover part that wraps and protects the suspension insulator, and the joint of the insulated wire and the human clamp from the human clamp. Consisting of a second cover portion, the first cover portion and the second cover portion, respectively, the 1-1, 1-2, 2-1, 2-2 cover pieces, 1-1, 1-2, and each having a semicircular cross section.
