Specific embodiment
The contents of the present invention are described in further details with reference to the accompanying drawings and detailed description.
Embodiment:
As shown in fig.3, the damper 100 provided in this embodiment for ultra-high voltage compound brace electrical equipment, this subtracts
Shaking device 100 includes the first cylinder body 1, the second cylinder body 2 and piston rod 3.
Wherein, one end of the piston rod 3 is mounted in the first cylinder body 1, hydraulic oil 4 is filled in the first cylinder body 1, with shape
At damping fuel tank, and the junction of piston rod 3 and the first cylinder body 1 then uses rubbery toroidal ring to guarantee that viscous hydraulic liquid will not occur
It leaks；The other end of piston rod 3 is then mounted in the second cylinder body 2 and flexible company is arranged between 2 bottom end inner wall of the second cylinder body
Fitting 5.That is, flexible connector 5 is mounted in the second cylinder body 2, the inner wall of the second cylinder body 2 can be to elastic connection
The circumferential deformation of part 5 plays solid Shu Zuoyong, improves the critical pressure that flexible connector 5 can bear when being pressurized.
As described in Figure 2, when 100 concrete application of this damper, it is mounted in the insulation in composite post class electrical equipment
On the interlayer diagonal line of son 101, to couple the movement at damper both ends and insulator layer diagonal line end node, make earthquake
It can sufficiently be moved freely with lower damper both ends and largely be consumed by the damping fuel tank of damper and flexible connector system
Seismic energy is dissipated, and the length of piston rod can then carry out accordingly according to the cornerwise length characteristic of be adapted to shock-damping structure interlayer
Adapt to adjustment.
When normal work, damper can carry out Two indices to the uncertain faint power effect occurred immediately and (hinder
Buddhist nun's fuel tank and flexible connector) parameter adaptive equalization consumption, under geological process, the peace of the first cylinder body 1 and the second cylinder body 2
Fill end generate random pulses excitation relative displacement and relative velocity, relative velocity pulse by between hydraulic oil 4 and piston rod 3 with
Speed index controls relevant viscous damping force and balances consumption, and relative displacement pulse by piston rod 3 and flexible connector 5 it
Between the adaptive elastic device balance of relevant to drift index control variation rigidity dissipate, only need to be according to the power of structural system itself
Characteristic matches the suitable coefficient of viscosity and variation rigidity hysteresis loop parameter, and damper can play displacement and speed double coordination optimization control
Effect, under geological process, by response do big layer movement the characteristics of, can be exaggerated instead damper elasticity and it is viscid
Index minimum limit value demand required for damping unit makes damper and Capacitor stack overall structure along tower body long side and short side side
To moving period and viscous damping and the vibration of Capacitor stack related direction meet the rigidity that most preferably consumes energy and damping condition, largely
Seismic energy it is depleted in damper, ensure that remaining geological process for the electrical equipment such as pipe bus 102 of surrounding
Seismic force with 103 internal action of current transformer is well below the limit value for working normally critical state.
It follows that damper provided in this embodiment be based on displacement and speed double coordinate and optimize control principle, pass through by
The both ends of piston rod 3 are separately mounted in the first cylinder body 1 and the second cylinder body 2, and a cylinder body is for balancing consumption relative velocity arteries and veins
Punching, another cylinder body make full use of Capacitor stack interlayer diagonal for balancing dissipation relative displacement pulse, concrete application when installing
The characteristics of knot point intercouples node movement and the movement at damper both ends, makes damper fully absorb seismic energy, enables
Bottom support insulator has to the effect of overall structure shock-damping energy-dissipating, reduces under the premise of meeting its basic function
Power effect of the adjacent interlayer insulator under earthquake, construction and principle are simple, and installation difficulty is not high.
Preferably, the one end of first cylinder body 1 is provided with first node mounting portion 11 to one kind as the damper, this
The one end of two cylinder bodies 2 is provided with second node mounting portion 21, in order to the fixed installation of damper.Specifically, the first segment
Point mounting portion 11 and second node mounting portion 21 are bolt mounting holes, to realize the detachable installation of damper.And the elasticity
Connector 5 is then using variable rate spring.
Simply to illustrate that technical concepts and features of the invention, its purpose is allows in the art above-described embodiment
Those of ordinary skill cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all
