Title:
METHOD FOR PERFORMING UNINTERRUPTIBLE POWER DISTRIBUTION WORK WITHIN SECTION IN DE-ENERGIZED LINE STATE BY SEPARATING WIRES WITHIN POLE-TO-POLE SPAN BY MEANS OF INSULATED LIVE WIRE GRIP AND BYPASS JUMPER CABLE
Document Type and Number:
WIPO Patent Application WO/2018/128269
Kind Code:
A1
Abstract:
The present invention relates to a method for performing uninterruptible power distribution work on a distribution line and, more specifically, to a method for performing uninterruptible power distribution work within a working section in a de-energized line state by separating wires within a pole-to-pole span by means of an insulated live wire grip and a bypass jumper cable, wherein: uninterruptible power distribution work can be forcibly performed directly on a live wire between poles located at the beginning and end of a working section without installing a bypass cable at the work site, the occurrence of safety accidents can be significantly reduced, and thus safe and efficient uninterruptible power distribution work can be carried out; and the work process employs a direct power transmission method in which power distribution work is performed by bypassing new and old wires, whereby, even when transformers are located at several points within a working section, uninterruptible power distribution work can be performed via one uninterruptible transformer apparatus by using, as the interruptible power distribution method, the direct power transmission method which requires no load transfer in the case of a heavy load line. Therefore, the working convenience, safety and economical efficiency can be improved.
