Description

Protection method for live wire work {PROTECTION METHOD FOR LIVE WIRE WORKING}

The present invention relates to a protection method for a live wire operation, and more particularly, to a protection device for a live wire operation capable of protecting all electrical power equipment without contacting the electric power equipment.

When working on a live wire in a distribution line, if there is a risk that an operator may come close to a 22.9kV power facility, a protective device should be used to protect the power facility. In this case, a generally used protective device is a rubber insulation blanket. This work can only be carried out with a direct live wire in which the worker directly contacts the power facility, but the current safety-oriented social atmosphere requires that it be performed with a non-contact indirect live wire work using an insulating stick for the safety of the worker.

In order to protect power equipment by indirect live wire work, it is necessary to use an insulation stick for indirect live wire to cover the electric power equipment with a rubber insulation blanket and fix it with insulating tongs. The conventional rubber insulation blanket was heavy and hard, so it was very difficult to handle it with an indirect live wire stick. Indirect live line protection is not possible with any type of protection equipment.

In addition, the rubber insulation blanket is heavy and hard, so it is difficult for two workers to lift it at the same time, and it is very difficult to fix the power equipment and the rubber insulation blanket together with the insulation tongs even if the rubber insulation blanket is covered because general electric power equipment is bent. . Therefore, the protective work of the rubber insulation blanket is carried out with a live wire directly in contact with the power equipment while wearing safety protection equipment such as rubber insulation sleeves and insulation rubber gloves.

A portion 140 may be formed. The penetrating portion 130 may be formed approximately in the central portion of the insulating sheet 100 , and the cutout 140 may be cut from one side of the through portion 130 to one side of the insulating sheet 100 , but The number and position of 140 can be variously applied as needed.

The insulating sheet 100 of this type can be used to wrap the insulating object 10 such as a steel rod or a transformer, and can be fixedly installed on the insulating object 10 by the gripping force of the sheet clip 200 to be described later. .

The seat clip 200 of the seat clip fixing step S300 shown in FIG. 1 or the seat clip mounting step S10 shown in FIG. 2 attaches the insulating sheet 100 to the outside of the insulating object 10 by the gripping force. In order to do this, the seat clip 200 is provided at the rear end of a pair of grippers 210 correspondingly rotatable with respect to the rotational shaft 201 and the gripper 210 with respect to the rotational shaft 201, and rotates. It may be provided with a pair of manipulation units 220 for closely contacting or spaced apart the holding unit 210 by the .

A pair of grippers 210 according to an embodiment of the present invention may have a gripping groove 211 concave on one surface facing each other so as to surround the outside of the insulating sheet 100 as shown in FIGS. 6 and 7 . The gripping groove 211 may form a concave curvature along the front and rear directions to wrap the outside of the insulating object 10 such as the electric pole 11 , and the gripping portion 210 may be made of high-strength plastic or the like.

A pair of gripping parts 210 according to another embodiment of the present invention has a concave wire fixing groove 212 on the opposite surface so as to wrap an insulating object 10 such as an electric wire 12 as shown in FIGS. 6 and 7 . can be formed to be A plurality of wire fixing grooves 212 may be arranged in a spaced apart state along the front-rear direction of the gripper 210 , and have different sizes to correspond to the diameter of the wire 12 and the like.

The protection method for live wire work according to the present invention is when performing indirect live wire work in a location where access is concerned within a safe distance (90Cm) between distribution line and live wire (e.g., when fastening a cable clamp with an indirect live wire during construction of a portable transformer method) , when the operator works within a safe distance from the transformer down-line and COS), and when there is concern about approaching within a safe distance from the existing live line section when working with an oblique line due to extension of high-voltage line or new branch construction (e.g., terminal high-voltage pole) It can be used when extending the line from the current line, protecting the existing line, installing insulators and wires, and then compressing the existing and new wires with an indirect live wire).

For example, in the case of protecting general materials such as insulators, steel rods, and devices, the insulation sheet (normal type, cut-out type, 100) is attached with the insulation stick 20 and then the insulation object 10 to be protected is covered. Thereafter, the holding part 210 of the sheet clip 200 may be spread apart with the insulating stick 20 to fix the insulating sheet 100 to the insulating object 10 to be protected.

In case of protecting wires such as jumper wires and transformer down wires, the wire to be protected is by attaching the seat clip 200 with the insulation stick 20 after combining the insulation sheet (straight type, 100) and the seat clip 200 (12) is fixed. Thereafter, the sheet clip 200 may be spread with the insulating stick 20 to secure the insulating sheet 100 to the wire to be protected.

The protection method for live wire work according to the present invention can radically prevent safety accidents by fundamentally blocking the worker's contact with the power line by working with an indirect live wire when carrying out protective work on an extra-high voltage distribution line.

And, by replacing the existing rubber insulation blanket with the insulation sheet 100, it is possible to protect the power equipment using the insulation stick 20 for indirect live wires easily, and to operate with the insulation stick 20 for indirect live wires. The insulating sheet 100 can be easily fixed to the power equipment by using a seat clip 200 that can be used.

In addition, when performing direct live wire protection work with the existing rubber insulation blanket, workers had to wear heavy safety protective gear. It's easier than this.

Although specific embodiments of the protection method for live wire work according to the present invention have been described so far, it is apparent that various implementation modifications are possible within the limits that do not depart from the scope of the present invention.

Therefore, the scope of the present invention should not be conveyed limited to the described embodiments, and should be defined by the following claims as well as the claims and equivalents.

That is, it should be understood that the above-described embodiment is illustrative in all respects and not restrictive, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and the meaning and scope of the claims; All changes or modifications derived from the concept of equivalents thereof should be construed as being included in the scope of the present invention.
