Description
Technical field
The present invention relates to shockproof, antidetonation, the seismic isolation technology neck of building, structures and equipmentTerritory, specifically refers to a kind of UHV shock insulation stopping means.
Background technology
Converter power transformer is electrical equipment most crucial in DC transmission engineering, converter power transformerHave the advantages that volume is large, quality is large, porcelain bushing shell is longer, under geological process (particularlyUnder high-intensity earthquake effect), by producing larger seismic force and displacement, cause change of current transformationThe destruction of device, threatens the security of operation of converter power transformer, directly causes economic great damageLose, more importantly can cause indirectly economic heavy losses and casualties, as affect earthquakeAfter earthquake relief work work and produce secondary disaster. By to repeatedly violent earthquake disaster both at home and abroadInvestigation, there are a lot of main transformer of transformer substations both at home and abroad and inclined in the time of earthquakeCover, the fracture of slippage and porcelain bushing shell etc., therefore the anti-seismic problem of transformer is building work alwaysOne of the study hotspot in journey, earthquake engineering and electrical engineering field. Traditional anti-shock methods isAdopt intensity, the rigidity of raising equipment, resist geological process, under geological process, thisKind method may be damaged under fortification intensity, and next in super fortification intensity effectCan avoid causing that the toppling of converter power transformer body, slip, fuel tank and device body spacing changeThe fault that causes, catch fire or casing failure,, because acceleration ratio is larger, be easier to meanwhileCan cause the on fire of converter power transformer. Therefore, for seismic losses mitigation, raising extra-high voltageThe earthquake safety of converter power transformer and the isolation energy dissipation damping control of carrying out equipment is veryNecessary.
Summary of the invention
Object of the present invention will provide that a kind of stability is high, good damping effect exactly, has softThe UHV shock insulation stopping means of spacing and anti-fall function.
For achieving the above object, the spacing dress of UHV shock insulation provided by the inventionPut, comprise upper and lower parallel upper junction plate and lower connecting plate, its special character is: described inBetween upper junction plate and lower connecting plate, be provided with four spacing shims, described spacing shim is by thinRubber layer, steel plate, rubber layer and envelope steel plate left-to-right are connected successively and pass through HTHP sulphurChange into integrative-structure, described spacing shim upper and lower side connects with upper junction plate, lower connecting plate respectivelyConnect, described spacing shim be positioned at upper junction plate, lower connecting plate surrounding and with upper junction plate, underBeing wired to of connecting plate central point is arranged symmetrically with.
As preferred version, the Thickness Ratio of described TR thin rubber layer and rubber layer is 1:10; DescribedEnvelope steel plate is provided with connecting bolt hole.
The invention has the advantages that: this device is in ensureing stability, and horizontal rigidityLittle, can improve the damping effect of shock insulation, there is soft spacing function, can ensure that shock insulation disappearsCan device in the safety of super generating geological process, and in the time that earthquake isolating equipment lost efficacy, still have oneFixed damping effect, has the function of fail safe. This stopping means cost is lower, structureSuccinctly, handsome in appearance, construction is simple, has good economy, environmental and social benefits.
The present invention is a kind of UHV with limit function, low-level rigidityShock insulation stopping means, it is handsome in appearance, simple in structure, stable performance, cost are relatively cheap,Construction and installation are easy, and the shock insulation power consumption that can be conveniently used in UHV subtractsShake, improves the earthquake safety that improves UHV greatly, particularly ensures specialThe safety of high-voltage commutation transformer under super generating geological process.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
UHV shock insulation stopping means as shown in Fig. 1～2, comprises parallel up and downUpper junction plate 1 and lower connecting plate 2, between upper junction plate 1 and lower connecting plate 2, be provided with four limitsPosition pad 3, spacing shim 3 is by TR thin rubber layer 31, steel plate 32, rubber layer 33 and envelope steel plate34 left-to-right connect successively and are sulfided into integrative-structure by HTHP, on spacing shim 3Lower end is connected with upper junction plate 1, lower connecting plate 2 respectively, spacing shim 3 be positioned at upper junction plate 1,Lower connecting plate 2 surroundings with the symmetrical cloth that is wired to of upper junction plate 1, lower connecting plate 2 central pointsPut.
As shown in Fig. 3～4, TR thin rubber layer 31 is 1:10 with the Thickness Ratio of rubber layer 33; Feng GangPlate 34 is provided with connecting bolt hole 4.
Stopping means of the present invention has limit function, can ensure shock insulation extra-high voltage converterTransformer stablizing under super earthquake intensity geological process. The UHV of application at presentEarthquake isolating equipment does not have spacing function, and in the time there is super generating earthquake, earthquake isolating equipment is likely sent outLife exceeds earthquake isolating equipment extreme displacement, causes unstability, destroys. And this Novel special high pressureConverter power transformer shock insulation stopping means, by soft spacing shim is set, is realized and being done in super generating earthquakeUsed time, the displacement of " soft " restriction shock-absorbing and energy-dissipating device, ensures the stable of shock-absorbing and energy-dissipating device.
When isolation energy dissipation bearing reaches after predetermined displacement, " soft " collided spacing pad by envelope steel plateThe TR thin rubber of sheet, is further evenly delivered to the thick rubber layer of spacing shim by steel plate. LimitAfter the gasket compression distortion of position, rigidity can be increasing, the horizontal position of restriction shock-absorbing and energy-dissipating deviceMove.
Spacing shim is mainly restriction shock-absorbing and energy-dissipating device earthquake isolating equipment under super fortification intensityHorizontal displacement, prevent the excessive and unstability of horizontal displacement. When isolation energy dissipation bearing reaches predeterminedAfter displacement, envelope steel plate is by the TR thin rubber of " soft " collision spacing shim, and TR thin rubber layer is by G3Rubber is manufactured, and is further evenly delivered to the thick rubber layer of spacing shim by steel plate, thick rubberAfter glue-line (being manufactured by G4 rubber) compression, rigidity can be increasing, restriction shock insulationThe horizontal displacement of energy dissipator, thus keep shock-absorbing and energy-dissipating device when " soft " is spacing,Ensure the stable of shock-absorbing and energy-dissipating device. Spacing shim is connected to envelope steel plate spacing by boltOn anti-drop device.
