Description

Indirect live line full-steel extension arm and indirect live line uninterruptible direct transmission line replacement method using the same without load transfer

[0001] The present invention relates to an indirect live-line operation for replacing a wire in a live-line distribution line, and more specifically, to an indirect live-line extension arm that enables easy replacement of a wire in a distribution line through indirect live-line operation without load transfer by directly transmitting the wire to the main line through movement or temporary installation of the wire with an indirect live-line extension arm, and to an indirect live-line uninterrupted direct transmission wire replacement method using the same that does not require load transfer.

[0002] In response to the recent surge in electricity demand, power facilities are continuously being expanded, and as power users' demands for electricity quality are increasing, even momentary power outages are becoming the subject of public complaints, leading to an increase in collective actions and lawsuits by power users seeking compensation. Therefore, uninterruptible power construction methods are being implemented to ensure a high-quality power supply during power distribution construction without cutting off the power.

[0003] Meanwhile, the existing distribution construction using the uninterruptible power method consists of the mobile transformer car construction method, the bypass cable construction method, and the construction switch construction method, but the bypass cable construction method is equipped with a cable car, cables required for the work section, construction switches, a mobile transformer car, a live-line bucket truck, and all pneumatic tools for live-line work, and bypasses the power supply by installing bypass cables, etc. through direct live-line work, and then replaces the distribution lines and replaces and relocates the wires, and then removes the bypass cables, etc. through direct live-line work to complete the distribution construction.

[0004] In addition, for distribution lines with a power line electric capacity exceeding 5,000 KW, when the existing bypass cable method is applied, since the allowable capacity of the cable for the existing cable method is 5,000 KW or less, a lot of time and labor costs are wasted in transferring the power load to other distribution lines to reduce the capacity of the distribution line to 5,000 KW or less, and there were serious problems in the stable operation of the distribution line system, such as accidents due to human error during load transfer work for temporary power transmission.

[0005] Accordingly, in recent years, indirect live-line work has been utilized to solve the above-mentioned problems by using indirect live-line work sticks and other insulating tools.

[0006] However, the general indirect live-line work as described above has the problem of causing safety accidents because the temporary transmission method using indirect live-line work is not able to properly replace the wires in distribution lines, especially in urban areas with heavy loads.

This can be done by installing it in the steel plate (20) of the position where the old wire (30) has been moved inside the work section using a suspension insulator, etc. through normal long-line and long-line work.

[0234] And when the old wire (30) on the outside of the work section where the moved old wire (30) is extended and the new wire (31) installed on the inside of the work section are connected on both sides with a new jumper wire (51), the moved old wire (30) and the new wire (31) are operated in parallel. After that, the separated primary side lowering wire (81) can be connected to the new wire (31).
