Abstract

The invention provides a damping device and a design method thereof. The damping device comprises a supporting mechanism (10) and a plurality of dampers (11); each damper (11) comprises a shell, an energy consumption element located in each shell, an elastic piece and a transmission shaft (3) sequentially penetrating through each shell and each elastic piece; and the supporting mechanism (10) is arranged in the middle of the bottom of electrical equipment (12), and the dampers (11) are fixed to the electrical equipment (12) through transmission shafts (3). Earthquake energy is dissipated through work of the energy dissipation element, and the damping effect is improved; and after the earthquake action disappears, the elastic piece can help the electrical equipment (12) restore the initial state.

Description

technical field [0001] The invention relates to an anti-seismic safety protection technology for electric facilities, in particular to a shock absorbing device and a design method of the shock absorbing device. Background technique [0002] Due to the uneven distribution of energy bases and power loads, a large number of substations (conversion) stations need to be built in unfavorable areas with high seismic intensity. More than 60% of the key equipment in the substation (converter) station are pillar electrical equipment (12) (circuit breakers, transformers, etc.). Such equipment usually uses porcelain materials to ensure insulation performance, and equipment to meet electrical clearance requirements The structure is thin and high, and it is difficult to take into account the seismic performance in design and manufacture, so the earthquake damage of pillar equipment is serious. [0003] The traditional shock absorbing device dissipates the seismic energy introduced into t...
