Description
Technical field
The utility model relates to shockproof, antidetonation, the seismic isolation technology field of building, structure and equipment, specifically refers to a kind of UHV shock insulation limit stoper.
Background technique
Converter power transformer is electrical equipment most crucial in the DC transmission engineering, converter power transformer has the advantages that volume is large, quality is large, porcelain bushing shell is longer, under geological process (particularly under the high-intensity earthquake effect), larger seismic force and displacement will be produced, cause the destruction of converter power transformer, threaten the security of operation of converter power transformer, directly cause economic heavy losses, more important is to cause indirectly economic heavy losses and casualties, as affects the earthquake relief work work after the earthquake and produce secondary disaster.By the investigation to domestic and international repeatedly violent earthquake disaster, occured both at home and abroad that a lot of main transformer of transformer substations topple when earthquake, the fracture of slippage and porcelain bushing shell etc., so the anti-seismic problem of transformer is one of the study hotspot in civil engineering, earthquake engineering and electrical engineering field always.Traditional anti-shock methods is intensity, the rigidity that adopts raising equipment, resist geological process, under geological process, this kind method may be damaged under fortification intensity, and cause that unavoidably distance between the toppling of converter power transformer body, slip, fuel tank and device body changes the fault that causes, catches fire or casing failure in that super fortification intensity effect is next, simultaneously, because acceleration ratio is larger, be easier to cause the on fire of converter power transformer.Therefore, for seismic losses mitigation, improve the earthquake safety of UHV and the isolation energy dissipation damping control of carrying out equipment is very important.
Summary of the invention
The purpose of this utility model will provide exactly that a kind of stability is high, good damping effect, has the UHV shock insulation limit stoper of soft spacing and anti-fall function.
For achieving the above object, the UHV shock insulation limit stoper that the utility model provides, comprise up and down parallel upper junction plate and lower connecting plate, its special way is: be provided with four spacing shims between described upper junction plate and the lower connecting plate, described spacing shim is by the thin rubber layer, steel plate, rubber layer be connected the steel plate left-to-right and connect successively and be sulfided into integrative-structure by High Temperature High Pressure, described spacing shim upper and lower end respectively with upper junction plate, lower connecting plate connects, and described spacing shim is positioned at upper junction plate, around the lower connecting plate and with upper junction plate, being wired to of lower connecting plate central point is arranged symmetrically with.
As preferred version, the Thickness Ratio of described thin rubber layer and rubber layer is 1:10; Described envelope steel plate is provided with the connecting bolt hole.
The utility model has the advantage of: this device is when guaranteeing stability, horizontal rigidity is less, can improve the damping effect of shock insulation, has soft spacing function, can guarantee that shock-absorbing and energy-dissipating device is in the super safety of sending out geological process, and when shock-proof device lost efficacy, still have certain damping effect, have the function of Fail safe.This limit stoper cost is lower, simple for structure, handsome in appearance, construction is simple, has good economy, environmental and social benefits.
The utility model is a kind of UHV shock insulation limit stoper with limit function, low-level rigidity, it is handsome in appearance, simple in structure, stable performance, cost are relatively cheap, construction and installation are easy, can be conveniently used in the shock insulation energy-dissipating and shock-absorbing of UHV, greatly improve the earthquake safety that improves UHV, guarantee that particularly UHV is in the super safety of sending out under the geological process.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
UHV shock insulation limit stoper shown in Fig. 1 ~ 2, comprise up and down parallel upper junction plate 1 and lower connecting plate 2, be provided with four spacing shims 3 between upper junction plate 1 and the lower connecting plate 2, spacing shim 3 is for by thin rubber layer 31, steel plate 32, rubber layer 33 be connected that steel plate 34 left-to-right connect successively and be sulfided into integrative-structure by High Temperature High Pressure, spacing shim 3 upper and lower end are connected with upper junction plate 1, lower connecting plate 2 respectively, and spacing shim 3 is positioned at around upper junction plate 1, the lower connecting plate 2 and with upper junction plate 1, being wired to of lower connecting plate 2 central points and is arranged symmetrically with.
Shown in Fig. 3 ~ 4, thin rubber layer 31 is 1:10 with the Thickness Ratio of rubber layer 33; Envelope steel plate 34 is provided with connecting bolt hole 4.
Limit stoper of the present utility model 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 insulation limit stoper is by arranging soft spacing shim, 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.
After the isolation energy dissipation bearing reached predetermined displacement, the envelope steel plate was with the thin rubber of " soft " collision spacing shim, and a nearly step evenly is delivered to the thick rubber layer of spacing shim by steel plate.After the spacing shim compressive strain, rigidity can be increasing, the Horizontal displacement of restriction shock-absorbing and energy-dissipating device.
Spacing shim 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 spacing shim, the thin rubber layer is made by G3 rubber, a nearly step evenly is delivered to the thick rubber layer of spacing shim 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.Spacing shim is connected to the envelope steel plate on the spacing anti-drop device by bolt.
