Description
Technical field
The present invention relates to a kind of pendulum-type damping device, and in particular to a kind of towering porcelain knob type electrical equipment pendulum-type damping dress
Put, belong to electrical equipment fixing device technical field.
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 is more and more elongated, and top quality is increasing, to its shock resistance
The requirement of energy 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 electrically set
The standby normal work under geological process is to ensureing that safe operation of power system is most important.
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 to have using base isolation technology come the seismic energy that dissipates at lower bracket
Input earthquake is isolated with electrical equipment, also had using tuned mass damper cushion technique；But said apparatus is in reality
Many problems are still had in the use of border, damping effect 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：It is static(al) method for strengthening.Equipment resistance is improved by increasing superfluous constraint flatly
The ability of brisance.Its principle is simply clear, but this reinforcing mode easily occurs in earthquake in pull bar or bracing wire fixed position
Damage, forms new weak link, simultaneously as the requirement of the mounting means and electric insulation of bracing wire, the present invention is to space requirement
Greatly.
(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.Its superiority is a lot, and floor space is small, and equipment arrangement center of gravity is low, and that at home and abroad also applies gets over
Come more.But GIS up-front investments are big, be distributing element investment 30-40 times；And GIS combination electric appliance once breaks down, after
Fruit is much more serious than open type transformer station；Meanwhile the leakage of sulfur hexafluoride gas the problems such as will also result in corresponding environment.
(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.It has largely in building structure field
Application example, technology maturation.But this method has two shortcomings to towering porcelain knob type electrical equipment, towering porcelain knob type is electrically set
The standby natural frequency of vibration of itself is just smaller, the damping effect unobvious after shock insulation.Base isolation is more suitable for shearing
The building structure that type destroys, the towering porcelain knob type electrical equipment effect destroyed to flexure type are poor.
(5) the porcelain knob type electrical equipment damping device based on tuned mass damper principle：It uses tuning quality to damp
Device principle, advantage are that cost is low, clear principle, increase top displacement unlike base isolation, can reduce top knot simultaneously
The acceleration and dynamic respond of structure.Shortcoming is that vibration frequency composition is very sensitive over the ground, damping effect with the change of earthquake motion and
Difference is obvious, and deviation is there may be between the actual control frequency of damping device and theoretially optimum value.
Towering porcelain knob type electrical equipment vibration prevention ability extreme difference, but because the requirement of equipment electronic functionality, its top shape
Shape and material not malleable.The present invention is bent according to the Failure type (flexure type destruction) of porcelain knob shape electrical equipment by discharging
The method of the free degree, devise coilable pendulum-type damping device.In addition, towering porcelain knob type electrical equipment is installed in certain height
At the top of the concrete column of degree, cement column bottom is changed to by the present invention on the premise of equipment setting height(from bottom) and shaped upper part is not changed
Mobilizable cambered surface, centre of twist point is located at apart from the position of ground certain altitude, reduce equipment and concrete column composition
Overall focus point distance reverses the distance of point, adds the stability of equipment, and causes equipment that identical windup-degree occurs
When, the horizontal displacement at the top of equipment is smaller.The damping rate of the present invention can be set by adjusting the parameter of spring and damper
Put, show different types of earthquake motion adaptability stabilization.
Compared with bracing wire reinforcement means, this method its upper side is disturbed it is small, it is small to space requirement, will not be formed new thin
Weak position；Compared with metal damping shock absorption method, this method stability is more preferable, and the sensitivity of vibration frequency composition is more over the ground
It is low；Compared with the foundation shock insulation method of the emission levels free degree, the porcelain knob type electrical equipment that this method is destroyed for flexure type
Damping effect is more obvious；Compared with multiple ring type tuned mass damper damping device, stability of the invention is more preferable, damping
Amplitude is higher.
