Shock insulation support and power supply system

Abstract

The invention provides a shock insulation support and a power supply system. The shock insulation support comprises an upper support plate, a lower support plate, a sliding block, a fixing device and a telescopic combined component. When an earthquake occurs, the shock insulation support consumes most of earthquake energy through friction sliding between the upper support plate and the sliding block and between the lower support plate and the sliding block. When the vertical earthquake action is large, the telescopic combined component increases the vertical rigidity of the support through connection of a vertical connecting rod, and meanwhile, the telescopic combined component is effectively connected with the fixing device, so that the combined structure can further increase the vertical anti-pulling rigidity of the support through the self weight of the fixing device and anchoring of the fixing device to the ground, so that the support is prevented from being pulled up or overturned due to the vertical earthquake, and the long-term effectiveness of the shock insulation support is protected.

Description

technical field [0001] The present application relates to an earthquake protection device, in particular to a shock-isolation support and a power supply system. Background technique [0002] As an important node in the UHV DC transmission project, the converter station can realize voltage rise and fall and AC-DC conversion, and the converter transformer is the key equipment in the station, and its safety affects the safety and stability of the entire transmission line. Due to electrical performance requirements, cantilever components such as bushings and low-strength materials such as ceramics are used in converter transformers, making them highly vulnerable to earthquakes and easily damaged. Therefore, the safety of key electrical equipment such as converter transformers is particularly important, which requires the use of shock-isolation supports to protect them. [0003] Sliding friction pendulum shock-isolation bearings have been used in building structure seismic isola...
