Description
Technical field
The utility model relates to power accessories technical field, especially particularly relates to a kind of two Split type lead spacer.
Background technology
The main application of power transmission sequence bundle conductor conductor spacer is relative motion between siding stopping wire and the geometry keeping bundle conductor under normal operating conditions.At a distance, the every phase conductor of jumbo ultra high-tension transmission line adopts two, four and above bundle conductor.The power transmission line of current 220KV and 330KV adopts binary fission wire, and 500KV power transmission line adopts tripartition and conductors on quad bundled, and voltage adopts six division and more polytomic wires higher than the ultra high-tension transmission line of 500KV.In order to ensure that bundle conductor wire harness spacing remains unchanged to meet electric property, reduce surface voltage gradient, and in a short-circuit situation, unlikely generation electromagnetic force between wire harness, cause the collision that attracts each other, though or cause the attraction collision of moment, accident can return to normal condition after eliminating, and thus separated by a distancely in span has installed conductor spacer.Installation interval rod also can play certain inhibitory action to the vibration of secondary span and aeolian vibration.
In China's 220kV binary fission transmission line of alternation current, 40-100 rice of being separated by each span will install a type bipartition conductor spacer, be used for maintenance two root wire spacing and suppress aeolian vibration, secondary span vibration, to ensure the safe operation of transmission line.But existing type bipartition conductor spacer is made up of the metal vaulting pole of two ends band bulb and the wire clamp of band ball-and-socket.Because described conductor spacer is all-metal manufacture, and do not have mosaic rubber block in wire clamp, it can only play interval supporting role to binary fission wire, can not keep the insulation between two root wires, and the performance eliminating conductor vibration is also very poor; But be among the natural environment of field due to a lot of wire, temperature changes with seasonal variations, and the cold phenomenon of heat expansion of wire can make the diameter of wire change to some extent, thus causes the hold power of conductor spacer on wire to be subject to certain impact; Again due to wire at run duration because diversified factor causes its operating temperature also to have change by a relatively large margin thereupon, the action effect of this variations in temperature is similar to thermal cycle, finally also wire clamp may be caused to decline to the power that holds of wire because causing bolt torque to decline.Conductor spacer directly may have influence on conductor spacer to the lower general who has surrendered that wire holds power may occur that slippage channels bit; cause the best position of conductor spacer off-design thus; thus do not have the fixing cord of design, protection circuit should be effective; even may new danger vibration be brought to wire in the position residing for certain conductor spacer particular moment, stress increases; even cause wire fatigue rate to be accelerated, and then cause serious accident and the losses such as circuit damage.
