Description

An insulator for an overhead distribution line with a processing line that can reduce the risk of electric shock.

The present invention relates to a method for preventing an electric shock hazard that can protect a worker from danger such as an electric shock accident while protecting the access of a bird and protecting an electric line and a distribution line from an external force together, Which can reduce the size of the insulated insulator.

Generally, the connection point of the power acid on a high-voltage or extra-high voltage (23 kV) processing power distribution line is connected to a support (pole) composed of insulated electric wire, human clamp, human clamp cover and insulator.

An anthropic clamp cover is put on the anthropic clamp connecting the insulator and the electric wire so that the charged portion of the connection point is insulated and used.

This can be done on the premise that an artificial approach such as live-line work is in progress.

Therefore, in the live-line operation, since the worker and the work equipment are frequently accessed, an insulating cover for the cushioning work having sufficient insulation characteristics and mechanical strength must be provided.

As a result, the Korean Utility Model Registration No. 20-0445173 (an insulating cover for live wire work with a working distribution line) is disclosed, which lowers the manufacturing cost, achieves lighter weight, and realizes safety by fully protecting the live part can do.

However, the above-described conventional technique is applied only to hanging insulators, and thus it is difficult to apply to a PL insulator installed in an ordinary electric pole. In particular, when a bird nestles around a pole around a nest, There has been a problem that an accident such as a short circuit occurs frequently, and further, in the case of the PL insulator, there is a serious problem leading to an electric shock accident when the operator is inadvertently exposed to the outside.

The present invention relates to a method and apparatus for cutting off the access of a bird and simultaneously protecting a worker from danger such as an electric shock accident while protecting a power distribution line and a power distribution line from an external force, There is a purpose to provide the insider.

According to an aspect of the present invention,

A plunger made of a synthetic resin material and having a bolt portion through which a nut of the wire is inserted and a fastening portion radially disposed around the bolt portion, the plunger being made of a synthetic resin material, A distribution line support formed of an insulator body for fixing and supporting a distribution line;

And an insulator is formed on the outer surface so as to face each other when the power line is inserted, and a terminal of the power line is detained at the end of the power line surrounded by the power line moved along the incision, An insulating cover made of a rubber material and having an opening integrally formed with the cover main body and having an opening corresponding to the coupling part and fixed to the plunger by detachment through a fastening means;

A vertical support protruding vertically and integrally with the fixing plate; a horizontal support extending horizontally from the upper end of the vertical support; and a reflector rotatably installed at the distal end of the horizontal support, And an access prevention mechanism.

According to this embodiment, since the distribution line and the distribution line support are enclosed by the insulation cover, contaminants from the outside can be prevented from entering the interior, and the distribution line and the distribution line support can be protected from the external force, In particular, since the rubber cover is in contact with the insulating cover due to the carelessness of the operator, there is an advantage that the operator can be safely protected from the danger such as an electric shock accident.

In addition, the reflection plate of the bird-access preventive device installed on the insulating cover can pre-reflect the sunlight and prevent the reflected light from interfering with the view of the bird, thereby preventing the bird from sitting on a power line or nesting around the wire.

In addition, since the insulating cover is made of rubber, it can be deformed and restored freely. Therefore, it is easy and easy to install the insulating cover by simply fitting it into the lower part or separating it from the upper part in the state where the power distribution line is fixed to the power distribution line support. And can be separated from each other.
