Description
Technical field
This utility model is related to cushion technique field, more particularly to it is a kind of for porcelain knob type electrical equipment damping based on every
The mixed control apparatus of shake principle and multiple tuned mass dampers principle.
Background technology
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 ensureing safe operation of power system.
Damage type in porcelain knob type electrical equipment earthquake is mainly insulator end and breaks 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 arranges metal damper come the seismic energy that dissipates at lower bracket, also has using base isolation skill
Art isolates input earthquake with electrical equipment；But said apparatus yet suffer from actual use many problems, damping effect
It is really undesirable, need further to be improved.
The advantage that this utility model compares with traditional porcelain column type electrical equipment shock-dampening method is made a concrete analysis of below.Existing method
Mainly there are stay-supported shock-dampening method, metal damper shock-dampening method, base isolation technical shock method, the combination of insulated full-enclosed formula
Electrical equipment 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 is improved by increasing superfluous constraint resist water
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 of bracing wire and electric insulation, this method pair
Space requirement is big.
(2) lead alloy damper shock-dampening method：By installing metal damping shock absorber, change the frequency of equipment, increase
The damping of equipment, reduces the earthquake response of equipment.At present the method has at home some applications, and Zhang Xuesong is in article《Install
The 220kV chopper shaketalle tests of NEW Pb amortisseur》The shaketalle test result of this amortisseur is given, is as a result shown
New lead alloy damper can reduce the acceleration at the top of chopper and displacement, and bottom porcelain bushing shell maximum strain can be reduced
More than 50%.But the method this two class spy of the Near-field ground motion for the abundant earthquake motion of long period composition and 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, it is quick or at a slow speed the element such as earthed switch, current transformer, spark gap, bus by closed composition, plus
It is mounted 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 little, 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 more serious than open type transformer station much；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, the absolute displacement of superstructure can be increased while damping, the earthquake motion enriched to long period composition
Damping effect is poor.
(5) the porcelain knob type electrical equipment damping device based on tuned mass damper principle：This method adopts tuning quality
Antivibrator principle, advantage is low cost, and clear principle increases top displacement unlike base isolation, can reduce simultaneously
The acceleration and dynamic respond of portion's structure.Have the disadvantage that over the ground vibration frequency composition is very sensitive, damping effect with earthquake motion change
Change and obvious difference, between the actual control frequency of damping device and theoretially optimum value deviation is there may be.
(6) this utility model is a kind of mixing based on base isolation principle and multiple tuned mass dampers shock absorption principle
Control device.This utility model has the respective advantage of Base Isolation Technology multiple tuned mass dampers technology, meanwhile, and greatly
Respective shortcoming is reduced greatly, can significantly reduce the dynamic response when earthquake motion of porcelain knob type electrical equipment is acted on, and to various
Uncertain factor is respectively provided with good robustness.The frequency spectrum that base isolation can change the earthquake motion that ground is transferred to equipment is special
Property so that the frequency content Relatively centralized on top is transferred to, while increasing top MTMD damping effects, MTMD is reduced to earthquake
The sensitivity of dynamic composition, while base isolation causes the vibration shape quality of top equipment basic vibration mode to participate in, than higher, reducing top
The impact of portion MTMD frequency misalignment effects.Compare with base isolation independent role, the utilization of MTMD can reduce equipment earthquake motion
Dynamic respond during effect, the shortcoming for overcoming the earthquake motion damping effect that base isolation enriches to long period composition poor.
Compare with bracing wire reinforcement means, little is disturbed to apparatus body, it is little to space requirement, do not form new weak part；
Compare with metal damping shock absorption method, damping rate and the stability shown to different type earthquake motion are more preferable；And base
Compare in the damping device of tuned mass damper, this utility model damping rate and stability are more preferable, to different type ground
The sensitivity of vibrations is lower；Compare with laminated rubber damping bearing shock-dampening method and Friction pendulum system shock-dampening method, this practicality
New horizontal absolute displacement is low, more preferable to the damping effect of Long-period Ground Motions.
