Abstract
A kind of release type damping conductor spacer that is used to keep power main interfascicular distance, by the chuck body, the chuck cover plate, support is formed, and the chuck body is fixedlyed connected with support, chuck body and chuck cover plate are rotationally connected, on the chuck body, be provided with chuck damping pad, on the chuck cover plate, be provided with chuck damping pad, on the chuck body, be provided with the dismountable bearing pin that is used for the tensioning clip epicranial plate, on chuck body and chuck cover plate, be respectively equipped with installing hole, on the chuck body, be provided with release aperture.Because the utility model has been offered release aperture on the chuck body, but form breaking section, make the utility model can either guarantee normal use, can make it again when meeting with power transmission line generation broken string accident, when chuck of the present utility model collision catenary baffle plate reaches certain impulsive force, but rupture at chuck body breaking section place, chuck comes off automatically, discharge lead, the tension force that prevents to break infringement electric power pylon.
Description
Technical field
The utility model relates to the electric power equipment of the clamping lead on a kind of AC, relates in particular to a kind of release type damping conductor spacer.
Background technology
In the high voltage large capcity transmission line, adopt large-section leads more, and whenever form, remain unchanged for guaranteeing every phase multiple conducting wires wire harness spacing by multiple conducting wires, prevent whiplash, inhibition aeolian vibration, inhibition subspan oscillation between the sub-conductor, need to install damping conductor spacer.
Big cross over that the transmission line span is big, lead intensity height, iron tower cost be also high.When broken string took place lead, if the conductor spacer wire clamp does not discharge lead, and broken string tension force reached certain degree, and then iron tower will suffer damage, and is serious even can cause down tower.For when breaking, protecting iron tower effectively, need conductor spacer is made release type.
Summary of the invention
It is a kind of when broken string takes place lead that the utility model provides, and the conductor spacer chuck can discharge the release type damping conductor spacer of lead.
The utility model adopts following technical scheme:
A kind of release type damping conductor spacer that is used to keep power main interfascicular distance, by chuck body 1, chuck cover plate 4, support 6 is formed, chuck body 1 is fixedlyed connected with support 6, chuck body 1 is rotationally connected with the chuck cover plate, on chuck body 1, be provided with chuck damping pad 2, on chuck cover plate 4, be provided with chuck damping pad 3, on chuck body 1, be provided with the dismountable bearing pin 5 that is used for tensioning clip epicranial plate 4, on chuck body 1 and chuck cover plate 4, be respectively equipped with installing hole, it is characterized in that on chuck body 1, being provided with release aperture 11.
Compared with prior art, the utlity model has following advantage:
Because the utility model has been offered release aperture on the chuck body, but form breaking section, make the utility model can either guarantee normal use, can make it again when meeting with power transmission line generation broken string accident, when chuck of the present utility model collision catenary baffle plate reaches certain impulsive force, but rupture at chuck body breaking section place, chuck comes off automatically, discharge lead, the tension force that prevents to break infringement electric power pylon.
