Abstract

The invention provides a lead alloy shearing-type damper used for support column-type electric equipment. The damper comprises a central shaft, a barrel body and a lead alloy component, wherein the central shaft is slidably sleeved in the barrel body; a first groove is formed in the outer wall of the central shaft; a second groove is formed in the inner wall of the barrel body; the first groove corresponds to the second groove in position, and a cavity is defined by the first groove and the second groove; the lead alloy component is embedded in the cavity and is matched with the cavity in shape; the first end of the central shaft is placed out of the barrel body, and is used for being connected with the electric equipment; and the barrel body is used for being connected with the base of the electric equipment. In the lead alloy shearing-type damper, the first groove is formed in the outer wall of the central shaft of the damper; the second groove which corresponds to the first groove in position is formed in the inner wall of the barrel body; the lead-aluminum alloy component is embedded in the cavity formed by the second groove and the first groove; and when the central shaft and the barrel body are diastrophic, seismic energy can be effectively absorbed after the lead-aluminum alloy component is shorn.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a lead alloy shear shock absorber used for pillar electrical equipment. Background technique [0002] 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-type electrical equipment has 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. Therefore, pillar-type electrical equipment in high-intensity earthquake areas often requires Take measures to install shock absorbers to ensure its anti-seismic safety. [0003] Existing shear type lead shock...
