Abstract
The invention provides a shock insulation device for overhead high-voltage equipment. The shock insulation device consists of a plurality of shock insulation device components(1) connected with one another, and a lower connecting board(2) is arranged at the lower part of the shock insulation device components(1) and connected with a top plate(6) of a frame(4) by bolts; an upper connecting board(3) is arranged at the upper part of the shock insulation device components(1) and is connected with a bottom plate(7) of the high-voltage equipment(5) by bolts; each shock insulation device component(1) consists of two semi-circular structures bended by a metal plate. The shock insulation device has small horizontal rigidity, but bigger vertical tension-compression rigidity, so that when the earthquake happens, the shock insulation device can resist the bigger upsetting moment generated by upper overhead equipment, simultaneously prolong the natural vibration period of the structure along the horizontal direction and reduce the earthquake response of the overhead high-voltage equipment, along with good resistance to capsizing and good shock insulation effect. The shock insulation device can be applied to all types of overhead high-voltage equipment of transformer stations, and the shock resistant and shockproof effects are obvious.
Description
Technical field
The present invention relates to shockproof, the anti-seismic technology field of building, structure and equipment, relate in particular to a kind of earthquake isolating equipment that is used for elevated high voltage electricity.
Background technology
High voltage electric equipment is as the visual plant in the power system, often be installed in and constitute support unit series connection system on the independent cantilever support, because support is to the amplification of seismic wave, and the form of structure of equipment is special, damping ratio is also less, porcelain spare in the equipment belongs to fragile material, plastic deformation ability is relatively poor, is easy to resonate in earthquake, becomes the antidetonation weak link in the power system, in near, modern earthquake, high voltage electric equipment all has infringement in various degree.Therefore, in order to alleviate earthquake loss, to improve the safety of electric fixtures and the damping control of carrying out equipment is very important.
At present, high voltage electric equipment damper commonly used has friction spring, friction pendulum system and elastomeric isolation pad with intermediate layers, use maximum elastomeric isolation pad with intermediate layers that is at home, but because elevated high voltage electricity produces bigger pulling force at the shock insulation layer under geological process, and the tension ability of rubber, drawn badly easily, the top elevated high voltage electricity is toppled.
Summary of the invention
The objective of the invention is to provides a kind of earthquake isolating equipment that is used for elevated high voltage electricity at defective of the prior art, its adopt have bigger vertical tension and compression rigidity, less horizontal rigidity and the stronger good elevated high voltage electricity earthquake isolating equipment of resistance to capsizing, isolating affection, thereby effectively overcome a series of problems of the described existence of background technology.
The technical solution adopted for the present invention to solve the technical problems is: the described earthquake isolating equipment that is used for elevated high voltage electricity, its earthquake isolating equipment is interconnected to constitute by a plurality of earthquake isolating equipment members 1, earthquake isolating equipment member 1 bottom is provided with lower connecting plate 2, and lower connecting plate 2 links to each other with the top board 6 of support 4 by bolt; Earthquake isolating equipment member 1 top is provided with upper junction plate 3, and upper junction plate 3 links to each other with the base plate 7 of high-voltage electrical apparatus 5 by bolt, and earthquake isolating equipment member 1 bends to two semi-circular structures by metal sheet and forms.
The present invention compares with background technology, the useful effect that has is: the earthquake isolating equipment of described elevated high voltage electricity, its horizontal rigidity is less, and vertical tension and compression rigidity is bigger, under geological process, this earthquake isolating equipment can be resisted the bigger overturning moment of the overhead electric generation in top like this, simultaneously in level to natural vibration period that can extending structure, reduce the seismic response of top high voltage electric equipment, resistance to capsizing, isolating affection are good.Can be used for all kinds elevated high voltage electricity in the transformer station, the earthquake resistance and prevention effect is remarkable.

The specific embodiment
Shown in Fig. 1,2,3,4, the earthquake isolating equipment of described elevated high voltage electricity, its earthquake isolating equipment is interconnected to constitute by a plurality of earthquake isolating equipment members 1, and earthquake isolating equipment member 1 bottom is provided with lower connecting plate 2, and lower connecting plate 2 links to each other with the top board 6 of support 4 by bolt; Earthquake isolating equipment member 1 top is provided with upper junction plate 3, and upper junction plate 3 links to each other with the base plate 7 of high-voltage electrical apparatus 5 by bolt, and earthquake isolating equipment member 1 bends to two semi-circular structures by metal sheet and forms.Described earthquake isolating equipment member 1 is that four and structure are identical, the angle a of the line OB of the mounting center point O of outer end points B of the line OA of the intermediate point A of two semi-circular structures of the first earthquake isolating equipment member 1-1 and the mounting center point O of earthquake isolating equipment member 1 and the first earthquake isolating equipment member 1-1, one side and earthquake isolating equipment member 1 approximates 45 ℃, and the first earthquake isolating equipment member 1-1, the second earthquake isolating equipment member 1-2, the 3rd earthquake isolating equipment member 1-3 and the 4th earthquake isolating equipment member 1-4 join end to end and constitute earthquake isolating equipment member 1.Lower connecting plate 2 is located at the both sides of earthquake isolating equipment member 1, and upper junction plate 3 is located at the middle part of earthquake isolating equipment member 1.
During enforcement, the described earthquake isolating equipment that is used for elevated high voltage electricity is arranged at the top of support, the bottom of electric fixtures, because the earthquake isolating equipment horizontal rigidity is smaller, earthquake isolating equipment is equivalent to low pass filter, and when seismic wave passes through the shock insulation layer, high-frequency signal will be filtered, and seismic signal mainly is a high-frequency signal, when seismic wave is delivered to the shock insulation layer, the seismic wave amplitude will reduce greatly like this, therefore can reduce the seismic response of superstructure.The horizontal rigidity and the vertical tension and compression rigidity of the diameter that the earthquake isolating equipment of described elevated high voltage electricity can also be by regulating each semicircle and the thickness adjusted earthquake isolating equipment of steel plate.
