This is about the live safety separation method.

As electric power demand has surged, electric power facilities corresponding thereto have been continuously expanded. As the demand level of electric power users has increased, momentary power outage has become a subject of complaints, and group actions of electric users such as compensation claims, There is an uninterrupted construction method in which the construction is carried out in a state in which the power is not cut off for the supply of good quality power during the power distribution work.

On the other hand, the conventional uninterruptible power distribution system consists of a mobile transformer, a by-pass cable system, and a construction switch system. However, the bypass cable system requires a cable, It is equipped with switchgear, mobile transformer car, live barge truck, and live air work unit. Bypass cable is installed by direct live operation to bypass power supply, and then replacement of power line, replacement of wastage and replacement work. And the bypass cable should be removed again for the job live operation to complete the distribution work.

In order to solve the above problems, the applicant of the present invention has proposed a method of securing a working space between the new and old wires in the Jeonju by using a wire line in Jeonju as shown in No. 20-0252786, Work was performed.

However, the above-mentioned wire-changing device is structured so that it is very difficult to manufacture, and it is possible to separate and connect the wire only within a certain range in which the rocking body rotates. In such a case, There is a problem in that it is impossible and ineffective as an indirect live-wire operation in the process of replacing the electric wire and the electric pole, which require a relatively sufficient safety work space.

Also, there is a serious problem that safety of a worker is threatened in a work process, such as that the wire line mechanism as described above is directly installed on the wire and directly performs live wire work to fix the live wire to the roller.
