And dismantling method of L-shaped end connection part for the transmission line, Drop Cloths and demolition jig to be used in the L-shaped end connection part of the dismantling method for power transmission line

摘要

PROBLEM TO BE SOLVED: To provide a method of disassembling an L-shaped terminating connection portion for a power transmission line, capable of ensuring the reliability of power supply by easily disassembling it in situ and replacing it by a section unit without using a crane or the like in an accident of the L-shaped terminating connection portion by establishing methods for in-situ assembly and disassembly of the L-shaped terminating connection portion, and capable of preventing splash of an insulator oil in a disassembling work or damage to a component such as an epoxy bushing owing to lateral swing in hanging the insulator tube, and to provide a curing sheet and a disassembling tool to be used for the method of disassembling an L-shaped terminating connection portion for a power transmission line.;SOLUTION: After a step of separating a conductor in the insulator tube, this method of disassembling an L-shaped terminating connection portion for a power transmission line has a step in which a cushionable curing sheet formed integrally with a silicone tube for draining an insulator oil is inserted into and closely bonded to the inner surface of the insulator tube, and a step in which the insulator oil in the insulator tube is drained via the silicone tube. Also, it has a step of disassembling the insulator tube for a bushing protective case of the L-shaped terminating connection portion after the step of draining the insulator oil in the insulator tube.;COPYRIGHT: (C)2009,JPO&INPIT
