Description
Technical field
The invention belongs to converting equipment anti-seismic technology field, especially relate to a kind of Anti-seismic transformer station pillar equipment connecting device of adjustable mounting position.
Background technology
Transformer station is the key component of electric power lifeline engineering, in the transformer station of voltage levels, and the structure type of most of equipment to be top be porcelain or compound insulator or sleeve pipe, bottom is steel construction pillar or support frame, as circuit breaker, and lightning arrester, capacitor, isolating switch etc.High pressure class electric equipment quality is large, and center of gravity is high, easily destroys under action of strong earthquake, and then causes the paralysis of electric power system to be disintegrated even comprehensively.The inefficacy of electric power system can cause serious disaster and huge economic loss, not only disaster relief work after impact shake, and thing followed secondary disaster also may cause more serious consequence.
The structure " top-heavy " of Switch equipment, easily produces larger inertia force under earthquake motion effect; Natural frequency and earthquake motion close, under earthquake motion effect, easily cause class to resonate; And damping is smaller, responds under earthquake motion effect comparatively greatly, decay slowly, very easily destroy in earthquake.In Tangshan Earthquake, circuit breaker damages and reaches 58%, and the spoilage of isolating switch is up to 30%, and lightning arrester damages and reaches 66%.In Wenchuan earthquake, electric equipment infringement is also very serious, wherein more than 252kV infringement 40, and more than 126kV damages 51.
In addition, due to the raising of electric pressure, porcelain equipment is difficult to meet requirement of strength, and composite material kind equipment use amount increases gradually.After stressed, as shaken minutely and under wind-force effect, easily occurring that slight residual is out of shape, there is the problems such as tractive in the coupling arrangement making Switch equipment be difficult to close a floodgate and pipe bus connects.In reality operation, also occurred that the quiet side contact of isolating switch after little shake produced distortion and situation about cannot normally close a floodgate, and made electric power system be difficult at short notice recover, cause large indirect economic loss.According to Practical Project service condition, for equipment such as isolating switches, due to the needs of its switching, error when it is installed or uses should be less than 1mm, for the post insulator that pipe bus connects, its required precision for position is higher, therefore uses the damping device that can regulate installation site, effectively can solve installation question and the response of reduction equipment under earthquake motion effect.
Because the damping of pillar class electric equipment is smaller, therefore become conventional selection to its increase high damping shock absorption facility.Within 1985, Zhou Shurui installs damping shock absorber research additional on rod insulator, find that damping efficiency can reach more than 50%, the people such as Huang Feng in 2010 use Finite Element to establish GW7-252 isolating switch model, and input resonance amplitude-modulated wave carries out seismic response analysis, finally between porcelain vase and support, adopt shock mitigation system, analysis result shows that damping effect reaches as high as 75%.The people such as Zhang Xuesong in 2013 are by test, and demonstrate and install before and after lead metal damping shock absorber, lightning arrester device frequency reduces, damping increased 3 times more originally, and make the strain of porcelain bushing root reduction reach more than 46%, and the earthquake motion of input is stronger, strain reduces more.
As shown in Figure 1; when using lead alloy damper; be that a metal protuberance thing is installed between electric equipment 1 body and pillar 4, play the effect of fulcrum, then on the flange in the bottom connecting plate 2 of electric equipment body, lead alloy damping device 3 is installed; during geological process; electric equipment 1 body around fulcrum, thus plays the object of protection electric equipment 1 body, but; due to its structure build-in attribute, there is following shortcoming in lead alloy damping device 3:
(1) vertically there is no damping effect, may destroy because electric equipment 1 body occurs to clash into fulcrum under Vertical Earthquake Loads;
(2) yield strength due to lead material is very little, and long wind action etc. can make connection loosen;
