Description
Technical field
The present invention relates to a kind of contact line or the Anti-galloping vibration absorbers of power transmission line.
Background technology
In recent years, high ferro industry in China's is fast-developing, main truss of the contact net as railway electrification project, makees in strong wind
Under, contact line can occur it is different degrees of it is upper and lower wave, contact line failure can be caused if the amplitude of oscillation is excessive, caused larger
Economic loss；Chinese national economy development simultaneously proposes higher demand to power industry, in overhead transmission line operational process
It can equally be waved under wind effect, the harm that conductor galloping generates is various, can such as cause line tripping, lead
Line electric arc burn, gold utensil damage, wire strand breakage, broken string, power transmission tower such as collapse at the consequences, even result in large-area power-cuts, cause weight
Big economic loss.Under high wind effect, transmission line galloping is excessive or even serious disastrous accident can occur.
Contact line or the Anti-galloping safety problem of power transmission line, which are undoubtedly, restricts rail transport industry and power industry development
One key factor.China is to wave disaster one of the countries with the most serious ..., therefore for the Anti-galloping of contact line or transmission line of electricity
Problem is the previous important topic urgently to be resolved hurrily of mesh.
A kind of solution of the above problem is to control power transmission line or contact net by installing Anti-galloping device at present
It waves.Traditional Anti-galloping device can only play the role of fixed wire rod, not any to the swing of wire rod under wind effect
Damping effect, wire rod swing caused by energy can not effectively be consumed, the swing protected mode of wire rod is compared
It is single, it is ineffective.Therefore a kind of waved to contact line or power transmission line charming appearance and behaviour while be fixed and control is developed, moreover it is possible to right
The Anti-galloping vibration absorber that the vibrational energy of wire rod is effectively dissipated is necessary.
Invention content
Goal of the invention：Technical problem to be solved by the invention is to provide a kind of contact line or the Anti-galloping vibration dampings of power transmission line
Device, the device can be applied on the contact net wire rod or power transmission network wire rod of different-diameter, which can not only play fixation
Connect the effect of both threads material, moreover it is possible under wind effect, damping effect be played to the swing of wire rod, to reduce the dance of wire rod
It is dynamic, and wire rod can also be prevented due to waving the danger for touching and causing together.
Invention content：In order to solve the above technical problems, the technology used in the present invention means are：
A kind of Anti-galloping vibration absorber of contact line or power transmission line, including vibration damping portion and it is symmetricly set on vibration damping portion both ends
