Description

Insulator integrated power line fixing device

The present invention relates to an insulator-integrated power line fixing device, and more particularly, by being implemented as an insulator-integrated type, it prevents inconvenience and loss of work time due to assembly with an insulator, and can be mounted and disassembled by using a tool for non-contact by an operator. It relates to an insulator-integrated power line fixing device that not only improves work efficiency by reducing the time required for installation and installation by providing a structure, but also prevents safety accidents, provides reliability of fixing power lines and convenience of disassembling power lines.

In general, a wangeum, which is an iron bar, is installed on the pole of a distribution line supplying electricity, and an insulator corresponding to a fraudulent insulator is installed on the wangeum to support the power line on the pole, and the separation of the power line on the insulator is installed. In order to prevent it, binds are used to tie the power lines to the insulator.

However, when the tide puts a tree branch or wire on the pole to build a house on the pole, the power line installed on the pole fails to block contact with the power line, resulting in an unexpected power outage, and the cover of the bind is damaged. There was a problem that caused the contact between the and Wankeum.

In addition, since the bind requires a lot of effort and time at the time of dismantling, it has a problem that not only significantly lowers the efficiency of the replacement work of the bind or insulator, but also impairs the safety of the worker.

In order to improve this problem, the Korean Utility Model No. 20-1999-0038816, "Bindless line post cover for power outage prevention," has been proposed. This is a combination of a plurality of fastening means being fastened to the fastener, but at both ends in the longitudinal direction. A binding line post cover in which a first connector having the same diameter and opened front and rear is formed, and a pedestal is formed to maintain coexistence with birds while a birdhouse is raised in the center; A clamp that is fastened by a fastening means, but is in close contact with the upper circumferential surface of the insulator and is symmetrical in a semicircular shape to firmly fix the bindless line post cover; One side is opened in the longitudinal direction to further extend the insulation length of the power line supported by the bindless line post cover, and then fixed with a plurality of latches and fastening bands integrally formed, and the length of the bindless line post cover A second connector that is larger than the diameter of the first connector is formed on one side so that any one of the first connectors formed at both ends of the direction can be inserted, and the other side is the same diameter as the first connector so that continuous insulation of the power line can be extended. It is composed of a connecting pipe formed with a third connector.

However, such a prior art requires considerable attention in handling the power line, due to the structural characteristic of being fixed to the insulator only when the power line is inevitably inserted first, and there are many risks in the replacement and installation of the bindless line post cover. As a result, it takes a lot of time and effort to work related to the power line, and has a problem that greatly impairs the safety of workers.
