Description
Technical field
The present invention relates to lightning rod technical field, is a kind of steel pipe lightning rod for mitigating wind-induced vibration.
Background technology
For preventing impact of the thunder and lightning to transformer station's transmission line of electricity, lightning rod is widely used in high voltage substation, and which belongs to high
Towering cantilever member, with slenderness ratio big, rigidity is little, shell is thin, from heavy and light the features such as, be typical wind sensitive structure, easily exist
There is wind-induced vibration under wind action, wind load often becomes one of primary load of control structure design；On the other hand, I
Before the substation section addressing Yushan Hill of the Northwest of state on the Gobi desert of alluviation flood sector, in site, physical features is open, subregion
The average maximum wind velocity of the high 10min of 10m that meets for interior 50 years one reaches 36.1m/s, and corresponding blast reaches 0.81kN/m2, and annual is big
Wind number of days 148.1 days, most Windy Days 202 days（More than 7 grades is strong wind, wind speed about 17m/s）, belong to continual strong wind environment,
Lightning-Rod Protection Disign In Substations under this specific harsh weather occur the probability that wind ruins accident greatly increase.
Content of the invention
The invention provides a kind of steel pipe lightning rod for mitigating wind-induced vibration, overcomes the deficiency of above-mentioned prior art, its
Under wind action, easily there is wind-induced vibration and reduce the power transformation under harsher wind conditions harsh weather in energy effectively solving lightning rod
Lightning rod of standing occurs wind to ruin the problem of the probability of accident.
The technical scheme is that and realized by following measures：A kind of steel pipe lightning rod for mitigating wind-induced vibration,
Including lightning rod body and steel pipe, on lightning rod body, coiling is fixed with steel pipe from bottom to top.
The further optimization and/or improvements being presented herein below to foregoing invention technical scheme：
Above-mentioned lightning rod body includes that hypomere, stage casing and epimere, hypomere and stage casing are fixedly installed togather, and stage casing and epimere are fixed
It is installed together, hypomere, stage casing and epimere link together tapered structure.
Above-mentioned hypomere, stage casing are identical with the wall thickness of epimere, and hypomere, stage casing and epimere wall thickness are 4cm to 8cm.
A diameter of 3cm to 5cm of above-mentioned steel pipe, the wall thickness of steel pipe is 0.5cm to 1cm.
Above-mentioned hypomere and stage casing are fixed together by flange, and stage casing and epimere are fixedly connected on one by flange
Rise.
Above-mentioned steel-pipe welding is on the outer wall of lightning rod body.
Present configuration is reasonable and compact, easy to use, is wound with steel pipe on lightning rod outer wall, in lightning rod wind-engaging
When, its leeward side will not form stable vortex, can effectively improve lightning rod starting of oscillation wind speed, mitigate lightning rod wind-induced vibration same
When the Lightning-Rod Protection Disign In Substations wind that reduces under harsher wind conditions harsh weather ruin the generation of accident.
Description of the drawings
Accompanying drawing 1 is the main structure diagram of preferred embodiment.
Coding in accompanying drawing is respectively：1 is hypomere, and 2 is stage casing, and 3 is epimere, and 4 is steel pipe.
Specific embodiment
The present invention is not limited by following embodiments, can technology according to the present invention scheme and actual conditions concrete to determine
