Frictional damping shock absorption device for electrical equipment

Abstract

The invention discloses a frictional damping shock absorption device for electrical equipment. The electrical equipment is pillar type electrical equipment, the device is located between the electrical equipment and an equipment support, and the device comprises a cylinder, a transmission shaft arranged coaxially with the cylinder, upper and lower frictional assemblies arranged symmetrically and coaxially, and a coaxial connecting rod located on one side of the inner wall of the cylinder, wherein the upper and lower frictional assemblies are composed of an inner ring and an outer ring with conical surfaces attached. According to the shock absorption device, the damping performance of the damping device is effectively improved through the two modes of friction and damping, and the service life of the damping device is greatly prolonged.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to a frictional damping shock absorbing device used for pillar electrical equipment in a substation. 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. The key equipment in the substation (converter) station is the pillar electrical equipment (lightning arrester, transformer, etc.). Such equipment usually uses porcelain materials to ensure insulation performance. However, the electrical clearance requires the equipment to be thin and high. Therefore, the design of the equipment It is difficult to balance the seismic performance with manufacturing, resulting in serious earthquake damage to pillar equipment. [0003] However, the existing shock absorbing devices have deficiencies in both structural design and material selection. T...

Problems solved by technology

The key equipment in the substation (converter) station is the pillar electrical equipment (lightning arrester, transformer, etc.). Such equipment usually uses porcelain materials to ensure insulation performance. However, the electrical clearance requires the equipment to be thin and high. Therefore, the design of the equipment It is difficult to balance the seismic performance with manufacturing, resulting in serious earthquake damage to pillar equipment

[0003] However, the existing shock absorbing devices have deficiencies in both structural design and material selection. The shock absorbing effect is only realized by frictional energy consumption, which makes it difficult to ensure the safety of electrical equipment and the stability of seismic performance, and cannot meet the requirements of electrical equipment in areas with high seismic intensity. equipment requirements
