[0010] However, in such various replacement devices,
When it became necessary to replace not the insulator alone but the entire insulator series, there was a problem that it was difficult to respond efficiently.
For example, at the time of replacement work, it is necessary to prepare a dedicated device for the insulator on the ground side, the line side, and the intermediate part, and to perform the replacement work, which is a dangerous work at a high place, sequentially at those three places. was there. Furthermore, since the insulator ream is usually composed of a large number of insulators alone, the insulator in the middle part cannot be replaced at one time, and the replacement work of the middle part must be performed several times according to the number of insulators. There is a problem that it is necessary to carry out the steps in sequence and it takes a lot of man-hours.

After being arranged in this manner, the hydraulic expansion / contraction device 53 of the link rod 5 is operated so as to shorten the entire length of the link rod 5. In this case, the entire load on the power transmission line and the like that the strain insulator device has borne is to be borne by the insulator ream 1a and the link rod 5 located laterally from the link rod 5. That is, since no load is applied to the insulator train 1b adjacent to the link rod 5, the connection between the respective constituent insulators is relaxed, and the insulator train 1b can be removed. In this case, the entire insulator row 1b can be removed at the same time, and, of course, it is possible to remove the insulator pieces 1b one by one upward from the lowermost insulator.

As described above, according to the attachment of this embodiment, the yoke can be easily bolted and fixed by using a pre-made bolt hole for mounting a horn or the like. Furthermore, the attachment has a large-diameter bolt hole 4 so that the end face of the yoke can be pressed when the link rod is contracted.
Since the four and 46 are provided, there is an advantage that the fixing strength of the yoke and the attachment in the contracting operation of the link rod or the structural strength required for the operation can be set to a sufficient marginal condition.
