Description

{APPARATUS FOR REPLACING INSULATOR}

The present invention relates to an insulator replacement apparatus which can be quickly operated so as not to be exposed to a danger for a long time when a damaged insulator is replaced due to a lightning or other impact.

Insulators located between the transmission line and the high-voltage wire are made of hard magnetic material and have good electrical insulation and are widely used because they do not deteriorate from the outside.

However, the insulators installed in the transmission line are subject to mechanical friction in longitudinal and transverse directions, depending on the vibration of the electric wire, and are often damaged by the leakage current and surge due to the high voltage power.

In order to replace the damaged insulator, the operator directly climbs up the transmission line and performs a replacement operation.

However, the replacement equipment used was so heavy that the worker had difficulty in carrying the equipment and climbing to the transmission line, and was also exposed to large and small risks at work. Especially, when the worker worked on the transmission line, the number of parts was considerable, and the time required was considerable.

As a conventional technique for solving such a problem, there have been proposed a plurality of interrupter exchangers which are lighter and can shorten the working time.

For example, a registration utility model 20-0303375 (registered on January 24, 2003) is provided with two rows of parallel wire ropes spaced apart with insulator supports having an insulator support, I suggest a replacement for my handicapped person.

As another example, the registrant's utility model No. 20-0477170 (registered on May 5, 2015) discloses a pair of insulators each of which is detached from each of the insulators located on both sides of the insulator, An attachment groove formed concavely in the inner circumferential surface of each of the pair of fixing portions, and an insulator replacement unit in which an outer circumferential surface is detachably coupled to the attachment groove to replace the defective insulator.

However, the alternator of this proposal was heavy and had a difficulty in working well.
