Abstract

The present invention relates to a method for mounting a human clamp cover using a jumper wire bend, wherein the step-by-step process comprises: a first step of attaching a rotor stick to the rotor stick coupling portion of the jumper wire band; a second step of seating the jumper wire bend on the jumper wire attached to the human clamp; a third step of operating the rotor stick to bend the angle of refraction of the jumper wire to the jumper wire extraction angle of the human clamp cover; and a fourth step of attaching the human clamp cover to the human clamp to which the bent jumper wire is attached using an auxiliary arm.

Description

Deadend Clamp Cover Installation Method Using Jumper Wire Bending Divide The present invention relates to a method of installing a human clamp cover to insulate the live part of the human clamp to which the jumper wire is attached, after bending the jumper wire (power line) drawn out from the human clamp to match the angle of the outlet of the human clamp cover when working with an indirect live line method of a 22.9KV-Y overhead distribution line. During periods when power quality was not critical for overhead distribution line work, the dead-line work method was applied after de-energizing the line. However, as industrial development has led to a demand for high-quality power without power outages, the direct live-line work method is being applied. While the direct live-line work method can improve the quality of power supplied compared to the dead-line work method, it has fatal problems that cause harm to workers, such as electric shock accidents. Accordingly, an indirect live-line method using insulating sticks and the like, which can ensure worker safety while maintaining high-quality power, has been developed and is being applied. However, when installing the human clamp cover on the human clamp, the jumper wire outlet of the human clamp cover is not straight but bent at about 50°, so the wire connected to the human clamp must also be bent to correspond to the angle of the jumper wire outlet of the human clamp cover. However, since the indirect live-line method does not involve the worker directly bending it by hand, the angle of the jumper wire connected to the human clamp and pulled out does not match the angle of the jumper wire pulled out of the human clamp cover, making it difficult to install the human clamp cover.
