Embodiment Construction

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0038] The present invention provides a shock absorber for pillar-like electrical equipment in substations, which ensures that the equipment is fixedly connected to the support under normal use, and under the action of an earthquake, reduces the seismic response of the equipment through frictional energy consumption. No residual deformation of the shock absorber.

[0039] In this embodiment, the shock absorber includes a left sleeve 1, a cylinder 2, a sliding wedge 3, a friction wedge, a locking nut 4, a right retaining cylinder ...

Abstract

Disclosed is a centering friction damper for a column-type electrical device, comprising a piston rod (8) and a cylinder barrel (2) provided with a disk spring (9), wherein two sides of the disk spring (9) are respectively connected to a sliding wedge block (3), and friction wedge blocks (5, 6) are provided in the sliding wedge block (3). The piston rod (8), when advancing from an outer side of the cylinder barrel (2) to an inner side thereof, squeezes the friction wedge blocks (5, 6) and the disk spring (9) so as to lower the seismic response of the electrical device by means of frictional energy dissipation. The centering friction damper for the column-type electrical device guarantees that, under the self-supporting effect of the column-type electrical device, no sliding displacement occurs in the damper, the damping efficiency is high, there is no residual deformation after unloading, and the structure is compact, and is convenient for installation.

Description

technical field [0001] The invention relates to a friction shock absorber for electrical equipment, in particular to a centering friction shock absorber for pillar electrical equipment. Background technique [0002] As an important part of lifeline engineering, people pay more and more attention to the anti-seismic ability of electrical equipment. In order to reduce the adverse effects of earthquakes on electrical equipment, not only good process layout is required, but also good anti-seismic / shock-absorbing performance . In the damping control system of electrical equipment, in addition to the need to develop a good performance shock absorber, the installation arrangement of the shock absorber also has an important impact on the performance of the shock absorber. In order to facilitate the popularization and application of the shock absorber, under the condition of satisfying the performance of the shock absorber itself, the shock absorber needs to be installed easily and ...
