Abstract

The invention discloses a damper. The damper comprises a center shaft, a cylinder body and a lead element, wherein the center shaft is rotatably sleeved in the cylinder body, moreover, a first groove is arranged at the outer wall of center shaft, a second groove is arranged at the inner wall of the cylinder body, the first groove is opposite to the position of the second groove and the first groove and the second groove are surrounded into a cavity; the first groove and the second groove are both in a square shape; the lead element is arranged in the cavity in an embedded mode and matched with the shape of the cavity; the first end of the center shaft is located outside the cylinder body and used for being connected with an electrical equipment; the cylinder body is used for being connected with an electrical equipment bracket. According to the damper, by mutual matching between the first groove and the second groove which are both in a square shape, stress area of the lead element is increased, when the center shaft and the cylinder body moves mutually crisscross, shearing force of the lead element is increased, so that under the condition of small area of the lead element, the yield force is increased, the distribution area of the stress flow is also increased, more earthquake dynamic energy is able to be absorbed continually, and the damping efficiency of the damper is improved.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to a shock absorber. Background technique [0002] At present, my country is located between the Eurasian seismic belt and the circum-Pacific seismic belt, and is an earthquake-prone country. The power equipment in substations and converter stations is a key link in the "lifeline project", so the importance of earthquake resistance is self-evident. Among them, pillar electrical equipment such as lightning arresters, transformers, pillar insulators, and switchgear equipment have structural characteristics that are not conducive to earthquake resistance, such as high center of gravity, large length-to-diameter ratio, natural vibration frequency close to seismic wave frequency, and high earthquake vulnerability. The pillar electrical equipment in the substation and converter station in the high seismic intensity area often needs to be installed with shock absorbers to en...
