Embodiment Construction
[0030] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0031] Such as Figure 1-2 As shown, a method for replacing tension insulators in the whole tower of UHV DC includes the following steps:
[0032] 1) When insulators and construction tools enter the site, arrange the construction tools neatly and conveniently for use; make safety preparations on site, including making construction site fences, placing safety production ten not dry signs clearly, and covering the site with colored strips of cloth ;Assemble the insulator on site for standby;
[0033] 2) Hang semi-permanent grounding wires on the front tension tower and rear tension tower adjacent to the construction tension tower, and use the Dinima rope as an anti-drop safety rope;
[0034] 3) Do ground anchor excavation and buried depth work well before the winching mill enters the site, and set up the pulley group at the steel wir...
