The present invention proposes rod-type tuned mass damper damping device, belongs to amping device technical field, the problem of solving porcelain knob type electrical equipment vibration prevention scarce capacity.The damping device includes support meanss, quality device and stiffness means；The quality device includes N grades of quality loops, wherein, N is positive integer；The stiffness means include N group level rigidity bars, and the quality loop is fixedly installed in above support meanss by rigidity bar, and the anchor ring of N grades of quality loops is in same plane, and using concentric circle patterns layout.The group level of the sum of series rigidity bar of the quality loop is corresponded.The damping device redundancy quality is extremely low, and damping stability is good, can disturb small to controlled device according to that need to use space allocation own dimensions, non-aging.
The present invention relates to rod-type tuned mass damper damping device, belong to amping device technical field.
Earthquake disaster has sudden and destructiveness, seriously threatens the safety of life and property of the mankind.Porcelain knob type is electric Equipment is applied widely in power system, and with the development of power industry, the grade more and more higher of power transmission and transforming equipment, High voltage electric equipment especially superhigh voltage DC power transmission and transforming equipment increasingly with it is fine and soft, top quality is increasing, to its antidetonation The requirement of performance is higher.Porcelain knob type electrical equipment earthquake is very serious in all previous macroseism both domestic and external, it is ensured that porcelain knob type is electric Equipment normal work under geological process is most important to guarantee safe operation of power system.
Damage type in porcelain knob type electrical equipment earthquake is mainly insulator end and broken and oil leak.For this case Problem, lot of domestic and international scholar takes different measures to improve its anti-seismic performance.Have by bracing wire reinforce etc. measure come Lateral rigidity is improved, what is had sets metal damper come the seismic energy that dissipates at lower bracket, also has using base isolation skill Art isolates input earthquake with electrical equipment, among these including laminated rubber bases and friction pendulum support etc..
Tuned mass damper (TMD) is a kind of passive seismic control device for being widely used in civil engineering structure, it Can be according to the seismic calamity of porcelain knob type electrical equipment, the acceleration of the lower porcelain knob type electrical equipment of reduction earthquake motion effect and root should Power is reacted.
TMD is made up of quality system, spring system and damping system.When earthquake occurs, controlled device is acted in earthquake Start vibration under, the vibration of controlled device drives TMD systems to vibrate jointly, because being that elasticity connects between TMD and controlled device Connect, relative motion can be produced between TMD and controlled device, if the TMD natural frequencies of vibration are adjusted into the porcelain knob type electricity with being controlled The close desired value of the gas equipment natural frequency of vibration (exact value can be determined by theoretical calculation), TMD is possible to be supplied to equipment one Individual power in opposite direction with equipment inertia force all the time, so as to reduce the amplitude made a concerted effort acted in equipment, is also just reduced The dynamic response of equipment when earthquake motion is acted on.From the perspective of power consumption, set and damp to TMD, dissipate ground by TMD motion Ground passes to the energy of equipment when shake occurs, and the consumption of energy is focused in TMD devices, and this reduces equipment institute in itself The energy absorbed is needed, the damage that equipment is likely to occur in itself is alleviated, so as to reach the purpose for mitigating equipment earthquake.
The advantage that the present invention is compared with traditional porcelain column type electrical equipment shock-dampening method is made a concrete analysis of below.Existing method is main There are stay-supported shock-dampening method, metal damper shock-dampening method, base isolation technical shock method, insulated full-enclosed formula combined electrical apparatus Power distribution equipment shock-dampening method, multiple ring type tuned mass damper damping device.
(1) stay-supported shock-dampening method：This method is static(al) method for strengthening.Equipment resistance water is improved by increasing superfluous constraint The ability of level land brisance.This method principle is simply clear, but this reinforcing mode is easily fixed in earthquake in pull bar or bracing wire Position is damaged, and new weak link is formed, simultaneously as the requirement of the mounting means and electric insulation of bracing wire, this method pair Space requirement is big.
(2) lead alloy damper shock-dampening method：By installing metal damping shock absorber, change frequency, the increase of equipment The damping of equipment, reduces the earthquake response of equipment.Current this method has some applications at home, and Zhang Xuesong is in article《Install The 220kV breaker shaketalle tests of NEW Pb damper》The shaketalle test result of this damper is given, is as a result shown New lead alloy damper can reduce the acceleration and displacement at the top of breaker, and bottom porcelain bushing shell maximum strain can be reduced More than 50%.But the earthquake motion that this method is enriched for long period composition and Near-field ground motion this two class spy containing velocity pulse The damping effect of different earthquake motion is relatively weak.
(3) laminated rubber damping bearing shock-dampening method：By changing equipment supporting condition, the natural vibration period of extension device, The predominant period section of earthquake motion is avoided, so that dynamic response of the top equipment under earthquake motion effect is reduced, while can also lead to Cross the measures such as increase lead for retractable pencil and carry out dissipation energy.This method has substantial amounts of application example, technology maturation damping effect in different field Also very well, but this method has the following disadvantages, it is the easy aging of rubber first, next to that base isolation would generally increase shock insulation branch There is wire connection the absolute displacement reaction of seat top equipment, most porcelain knob type electrical equipment upper ends, and the increase of displacement is held Easily there is equipment because of the situation that wire is pulled and destroys, the 3rd is shock isolating pedestal not tension, even if not considering laminated rubber shock insulation The both of the aforesaid shortcoming of bearing shock-dampening method, this method is generally also only used for the transformer top set that substrate occurs without tension Pipe damping, is difficult to apply to be directly installed on the damping of the porcelain knob type electrical equipment such as large-scale current transformer, the arrester on ground.
(4) Friction pendulum system shock-dampening method：By changing equipment supporting condition, the natural vibration period of extension device, avoid ground The predominant period section of vibrations is to reduce the dynamic response of equipment.Friction-pendulum shock-insulation support combines the general of sliding bearing and pendular motion Read, mainly determined using the frequency of system after earthquake isolating equipment by the geometric parameter put, while the Friction dissipation for passing through sliding surface Energy.Friction-pendulum shock-insulation device is gone back in the existing substantial amounts of application of building field, but in the damping application of porcelain knob type electrical equipment There are problems that, one be increased top equipment displacement, two be this shock isolating pedestal not tension.
(5) totally enclosed type combined electrical apparatus power distribution equipment (GIS) shock-dampening method:Different from ordinary distribution device, GIS is by open circuit Device, disconnecting switch, it is quick or at a slow speed the element such as earthed switch, current transformer, arrester, bus by closed composition, plus In the storehouse of the SF6 gases full of certain pressure, electric insulation can ensure that SF6 gases are simultaneously by SF6 gases in storehouse Also arc-extinguishing medium is played.The superiority of this method is a lot, and floor space is small, and equipment arrangement center of gravity is low, at home and abroad also should It is more and more.It is 30-40 times of distributing element investment but GIS up-front investments are big；And GIS combination electric appliance once occurs Failure, consequence is much more serious than open type transformer station；Meanwhile, the leakage of sulfur tetrafluoride gas will also result in corresponding environment etc. Problem.
(6) the multiple ring type tuned mass damper damping device (patent No.：ZL 201520260800.7)：This method is adopted Tuned mass damper principle is used, has the advantages that cost is low, small to space requirement, be substantially not present problem of aging.But originally The deformable scope for the ring type spring that method is used is relatively small, not enough to special violent earthquake margin of safety.
