Description
Technical field
The present invention relates to cushion technique field, more particularly to it is a kind of former based on shock insulation for porcelain knob type electrical equipment damping
The mixed control apparatus of reason and multiple tuned mass dampers principle.
Background technology
Earthquake disaster has sudden and crushing, and serious threat 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 that insulator end is broken and oil leak.For this case
Problem, lot of domestic and international scholar take different measures to improve its anti-seismic performance.Some by bracing wire reinforce etc. measure come
Lateral rigidity is improved, some sets metal damper also to have using base isolation skill come the seismic energy that dissipates at lower bracket
Art isolates input earthquake with electrical equipment；But said apparatus still has many problems, damping effect in actual use
Fruit is undesirable, needs further to be improved.
The advantages of concrete analysis present invention is compared with traditional porcelain column type electrical equipment shock-dampening method 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.By increasing superfluous constraint water is resisted to improve equipment
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 forms new weak link, 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, reduce the earthquake response of equipment.This method has some applications at home at present, and Zhang Xuesong is in article《Installation
The 220kV breaker shaketalle tests of NEW Pb damper》Give the shaketalle test result of this damper, the results showed that
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) 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, quick or the element such as earthed switch, current transformer, arrester, bus by closed composition, adds at a slow speed
In the storehouse of the SF6 gases full of certain pressure, electric insulation can rely on SF6 gases in storehouse to ensure that SF6 gases are simultaneously
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.But GIS up-front investments are big, be distributing element investment 30-40 times；And GIS combination electric appliance once occurs
Failure, consequence are much more serious than open type transformer station；Meanwhile the leakage of sulfur tetrafluoride gas will also result in corresponding environment etc.
Problem.
(4) foundation shock insulation method：By changing equipment supporting condition, the natural vibration period of extension device, earthquake motion is avoided
Predominant period section, so as to reduce dynamic response of the top equipment under earthquake motion effect, while can also be by increasing lead for retractable pencil etc.
Measure carrys out dissipation energy.This method has substantial amounts of application example in different field, and technology maturation damping effect is also fine, but this
There are two shortcomings in method, can increase the absolute displacement of superstructure, the earthquake motion enriched to long period composition while damping
Damping effect is poor.
(5) the porcelain knob type electrical equipment damping device based on tuned mass damper principle：This method uses tuning quality
Damper principle, advantage are that cost is low, clear principle, increase top displacement unlike base isolation, can reduce simultaneously
The acceleration and dynamic respond of portion's structure.Shortcoming is that vibration frequency composition is very sensitive over the ground, damping effect with earthquake motion change
Change and difference is obvious, damping device actual control there may be deviation between frequency and theoretially optimum value.
(6) present invention is a kind of mixing control based on base isolation principle and multiple tuned mass dampers shock absorption principle
Device.The advantages of present invention has Base Isolation Technology multiple tuned mass dampers technology each, meanwhile, greatly reduce again
The shortcomings that respective, can significantly reduce the earthquake motion of porcelain knob type electrical equipment effect when dynamic response, and to it is various it is uncertain because
Element is respectively provided with good robustness.Base isolation can change the spectral characteristic that ground is transferred to the earthquake motion of equipment so that pass
The frequency content Relatively centralized on top is handed to, while increasing top MTMD damping effects, reduces MTMD to earthquake motion composition
Sensitivity, while base isolation make it that the vibration shape quality participation ratio of top equipment basic vibration mode is higher, reduces top MTMD frequencies
The influence of rate effect of detuning.Compared with base isolation independent role, MTMD utilization can be reduced when equipment earthquake motion acts on
Dynamic respond, overcome the shortcomings that base isolation is to long period composition abundant earthquake motion damping effect difference.
Compared with bracing wire reinforcement means, it is small to apparatus body interference, it is small to space requirement, new weak part is not formed；
Compared with metal damping shock absorption method, damping rate and the stability shown to different type earthquake motion are more preferable；And base
Compared in the damping device of tuned mass damper, damping rate of the present invention and stability are more preferable, to different type earthquake motion
Sensitivity it is lower；Compared with laminated rubber damping bearing shock-dampening method and Friction pendulum system shock-dampening method, water of the invention
Flat absolute displacement is low, more preferable to the damping effect of Long-period Ground Motions.
The content of the invention
Instant invention overcomes above-mentioned the deficiencies in the prior art, there is provided a kind of mixing for porcelain knob type electrical equipment damping
Control device.The present invention has good damping effect and damping stability, can effectively prevent electrical equipment from making in macroseism
Destruction under.
