Multi-dimensional combined seismic isolation support

Abstract

The invention discloses a multi-dimensional combined seismic isolation support. The multi-dimensional combined seismic isolation support comprises a support panel 1, the support panel 1 is fixedly supported by at least four single vibration isolators 2, the support panel 1 is used for mounting pillar type electrical equipment 3, and the center position of the support panel 1 is used for mounting the pillar type electrical equipment 3. Each single vibration isolator 2 comprises a bottom mounting plate 21, rubber steel wire rope dampers 22, a top mounting plate 23 and a viscous damper 24, the at least two overlapped rubber steel wire rope dampers 22 are mounted in the middle of the bottom mounting plate 21, the axes of the rubber steel wire rope dampers 22 coincide with the symmetry axis of the bottom mounting plate 21, the top mounting plate 23 is mounted above the rubber steel wire rope dampers 22 on the uppermost layer, and the viscous damper 24 is further connected between the top mounting plate 23 and the bottom mounting plate 21. According to the multi-dimensional combined seismic isolation support, the multi-dimensional seismic mitigation and isolation requirement of ground input can be met, the rotation effect of equipment under the seismic action can be achieved, the equipment distance requirement is met, and good multi-dimensional seismic mitigation and isolation efficiency is provided.

Description

technical field [0001] The invention belongs to the technical field of shock absorption and isolation for electric equipment, and in particular relates to a multi-dimensional earthquake combined shock isolation support. Background technique [0002] As an important infrastructure related to national security and the lifeline of the national economy, the power system must not only meet reliable operation under normal circumstances, but also need to be able to maintain necessary functions when extreme disasters such as earthquakes occur. Therefore, building a resilient power grid with resilience has gradually become a national strategy for governments to develop. [0003] Earthquake disasters in recent years have shown that due to the large height, high center of gravity and low strength, the pillar electrical equipment in substations and converter stations has high seismic vulnerability. From an electrical point of view, a typical substation contains a complete set of interc...
