The electric power is related to the development of national economy, the life of people and the stability of society. The safety of the power grid is an important component of the public safety of the society.
As an important component of "lifeline engineering" which has a great influence on the nationality of people, once an electric power system fails or is damaged, serious disasters and immeasurable economic losses can be caused; the power interruption not only seriously affects normal production life and earthquake relief work, but also possibly causes secondary disasters such as fire and the like, and seriously threatens the life and property safety of people. Among various natural disasters experienced by human beings, a strong earthquake is one of the disasters with the greatest threat to life line engineering. Earthquake disasters are not only reflected in that various structures can be seriously damaged in strong earthquakes, but also can cause the functions of various lifeline engineering systems to be greatly damaged or even completely lost.

Detailed Description
Spatially relative terms such as "above … …", "above … …", "above … …", "above", and the like, may be used herein for ease of description to describe the spatial relationship of one feature or characteristic to another feature or characteristic as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
As shown in figure 1, a GIS equipment vibration isolation design structure is arranged by adopting a sliding vibration isolation device 1 and a rubber vibration isolation device 2, wherein the sliding vibration isolation device is arranged along the axis of the GIS equipment, and the rubber vibration isolation device is arranged around the sliding vibration isolation device as the center.
For equipment such as GIS, the mass of the upper part is not large enough, the gravity center is low, and the rigidity of a rubber shock isolation support system is too large, so that the shock isolation device is difficult to perform effective horizontal motion under the action of an earthquake, and the shock isolation effect is seriously influenced. And the damping of the sliding shock insulation support is relatively small, the horizontal displacement is large, and the damage of equipment is easily caused by the excessive displacement of the shock insulation device in the shock insulation process. In view of this, the two vibration isolation devices are arranged in a mixed mode, so that on one hand, the rigidity and the natural frequency of the system are reduced, and on the other hand, the high-efficiency energy consumption effect of the rubber vibration isolation device is fully exerted.
As shown in the attached figure 1, the arrangement diagram of the vibration isolation devices of certain 220kV GIS equipment is that the sliding vibration isolation devices are arranged along the axis of the GIS equipment, and the rubber vibration isolation devices are arranged around the sliding vibration isolation devices by taking the sliding vibration isolation devices as the center, specifically, the sliding vibration isolation devices are positioned in the center of a Chinese character 'tian', and 8 rubber vibration isolation devices are positioned around the Chinese character 'tian'.
As shown in fig. 2 and 3, the sliding seismic isolation apparatus includes an upper support plate 11, a lower support plate 12, and a hinge slider 13; the bottom of upper bracket board is equipped with slider and holds chamber 14, be equipped with slip sphere 15 on the bottom suspension bedplate, the bottom of articulated slider with the cooperation of slip sphere, the upper portion of articulated slider is deep into the slider holds the intracavity. And the upper support plate and the lower support plate are respectively and correspondingly provided with a limiting block 16. The low friction material 17 is coated between the hinged slider and the sliding spherical surface.
As shown in fig. 4, the rubber-vibration isolation device 2 includes an upper buttress 21, a lower buttress 22, a connecting steel plate 23, an embedded steel plate 24, an embedded sleeve 25, a thin steel plate and rubber; the thin steel plates and the rubber are mutually overlapped and vulcanized to form an integral rubber block 26, the upper end and the lower end of the rubber blocks are respectively connected with the connecting steel plate through bolts, the embedded steel plates and the embedded sleeves are respectively fixed inside the upper buttress and the lower buttress, and the connecting steel plates are connected with the embedded sleeves through mounting bolts 27. The laminated rubber shock isolation device is formed by mutually laminating thin steel plates and rubber layer by layer and bonding the thin steel plates and the rubber through a special vulcanization process, and the structure, the formula and the process of the laminated rubber shock isolation device need special design and belong to a thick rubber product. The mechanical properties of the laminated rubber shock isolation device are as follows: first, compression performance. The longitudinal bearing capacity of the compression performance of the laminated rubber shock isolation device is much larger than that of rubber, and is equivalent to that of a reinforced concrete column with the same section. Second, the tensile properties. The elastic stiffness of the laminated rubber seismic isolation device when being pulled is only about 1/10 when being pressed. When the multilayer rubber is compressed after being subjected to large tensile deformation, the compressive stiffness is reduced to about 1/2 of the initial stiffness. Third, durability. The durability of the laminated rubber seismic isolation device depends on the rubber. Rubber with good durability is adopted as a protective layer, and the rubber with CR and polytetrafluoroethylene coated on the surface of NR meets the durability of the support body for 100 years. Therefore, the laminated rubber seismic isolation device is used as a structural member, and the durability of the laminated rubber seismic isolation device is equivalent to the service life of a building.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
