The beneficial effects of the utility model are as follows:
One, novel UHV shock-absorbing and energy-dissipating device horizontal rigidity are little, and converter power transformer is had good damping effect.Shock-absorbing and energy-dissipating device for converter power transformer is not yet arranged at present.The utility model proposes a kind of novel UHV shock-absorbing and energy-dissipating device first, the rubber earthquake isolation support individual layer rubber layer thickness that it adopts is more than the twice of rubber earthquake isolation support for building, total height remains unchanged, unidimensional novel shock-absorbing and energy-dissipating device is that rubber earthquake isolation support for building is below 0.5 times, can effectively reduce the horizontal rigidity of damping support, significantly improve the earthquake isolation effect to UHV, and stability be substantially constant.
Two, novel UHV shock-absorbing and energy-dissipating device has limit function, can guarantee shock insulation UHV stablizing under super earthquake intensity geological process.The UHV shock-proof device of using does not at present have spacing function, and when super earthquake occured, shock-proof device might exceed the shock-proof device extreme displacement, causes unstability, failure.And this novel UHV shock-absorbing and energy-dissipating device is by arranging soft limit stoper, is implemented in superly when sending out geological process, and the displacement of " soft " restriction shock-absorbing and energy-dissipating device guarantees the stable of shock-absorbing and energy-dissipating device.
Three, novel UHV shock-absorbing and energy-dissipating device has anti-drop, can guarantee the vertical stability of shock insulation UHV under super earthquake intensity geological process, and after shock-absorbing and energy-dissipating device lost efficacy, still has certain damping effect.The UHV shock-proof device of using at present is when vertical unstability, and then converter power transformer will fall from damping support, cause the destruction of converter power transformer.
Four, novel UHV shock-absorbing and energy-dissipating device cost is low.If shock-absorbing and energy-dissipating device directly adopt common buildings with damping support to the UHV shock insulation, in order to reduce the horizontal rigidity of shock-proof device, usually adopt the mode of series parallel connection damping support to the UHV shock insulation, each shock-proof device is then minimum like this forms (damping support is two-layer, four every layer) by 8 above damping supports.And the damping support that this novel UHV shock-absorbing and energy-dissipating device adopts is comprised of single damping support, then reduces by a relatively large margin engineering cost.
Working principle of the present utility model and process are as follows: this installs between UHV and basic raft plate, shock insulation energy-dissipating device top is connected with UHV by precast reinforced concrete beam plate or girder steel, the bottom directly is connected with basic raft plate, adopt this scheme can make the arrangement of shock insulation energy-dissipating device not be subjected to top UHV equipment shape limitation, be convenient to the standardization of arrangement, 9 independently shock insulation energy-dissipating devices are set under each UHV of this arrangement.
Each novel shock-absorbing and energy-dissipating device presses damping support and four spacing anti-drop devices to form by a low rigidity, bottom surface, by upper lower connecting plate and converter power transformer ground be connected the raft plate top surface and be connected.Under geological process, after the displacement of isolation energy dissipation bearing reached predetermined displacement, the thickening envelope steel plate of damping support was with the soft collision limit stoper, and the Horizontal displacement of restriction shock-absorbing and energy-dissipating device prevents the excessive unstability that causes of isolation energy dissipation bearing Horizontal displacement.
Each spacing anti-drop device is comprised of a limit stoper and an anti-drop device.After the isolation energy dissipation bearing reached predetermined displacement, the envelope steel plate was with the thin rubber of " soft " collision limit stoper, and a nearly step evenly is delivered to the thick rubber layer of limit stoper by steel plate.After the limit stoper compressive strain, rigidity can be increasing, the Horizontal displacement of restriction shock-absorbing and energy-dissipating device.
Damping support in the shock insulation energy-dissipating device loses vertical stability, and after the inefficacy, then the top converter power transformer is then by the anti-drop device vertical supporting, when falling, anti-drop device is supported by the thin rubber of anti-drop device first, plays buffer function, then is delivered to thick rubber layer, cause thick rubber layer vertical deformation, along with distortion increases, rigidity is increasing, the restriction vertical deformation, anti-drop device can produce shear deformation in the horizontal direction simultaneously, and substantially horizontal plays cushioning effect.
Damping support of the present utility model has bottom surface pressure, end horizontal rigidity.It adopts the individual layer rubber layer thickness is more than the twice of rubber earthquake isolation support for building, total height remains unchanged, unidimensional novel shock-absorbing and energy-dissipating device is that rubber earthquake isolation support for building is below 0.5 times, therefore can effectively reduce the horizontal rigidity of damping support, thereby improve the earthquake isolation effect to UHV, and stability is substantially constant.
Limit stoper mainly is the Horizontal displacement of restriction shock-absorbing and energy-dissipating device shock-proof device under super fortification intensity, prevents the excessive and unstability of Horizontal displacement.After the isolation energy dissipation bearing reaches predetermined displacement, the envelope steel plate is with the thin rubber of " soft " collision limit stoper, the thin rubber layer is made by G3 rubber, a nearly step evenly is delivered to the thick rubber layer of limit stoper by steel plate, after thick rubber layer (being made by the G4 rubber) compressive strain, rigidity can be increasing, the Horizontal displacement of restriction shock-absorbing and energy-dissipating device, thereby keep shock-absorbing and energy-dissipating device when " soft " is spacing, guarantee the stable of shock-absorbing and energy-dissipating device.Limit stoper is connected to the envelope steel plate on the spacing anti-drop device by bolt.
Anti-drop device is comprised of thin layer rubber (G3 rubber), one deck laminated steel plate and envelope steel plate.After lead for retractable pencil shock-proof device in the novel shock-absorbing and energy-dissipating device lost efficacy, the top converter power transformer is with the Contact Thin rubber layer, " soft " of realizing converter power transformer falls, converter power transformer gravity evenly is delivered to thick rubber layer by steel plate, thick rubber layer vertical deformation, rigidity is increasing, the restriction vertical deformation, anti-drop device can produce shear deformation in the horizontal direction simultaneously, and substantially horizontal plays cushioning effect.When therefore anti-drop device has anti-drop, have certain damping effect, realize that novel shock-absorbing and energy-dissipating device has the function of Fail safe.
