Four-point type electrical equipment shock-absorbing method and shock-absorbing system

Abstract

The invention provides a four-point type electrical equipment shock-absorbing method and a shock-absorbing system. The method comprises the following steps: acquiring parameters, wherein the parameters comprises the number n of preset absorbers, edge length of a square formed by four absorbers arranged in a square and symmetric manner, seismic fortification intensity and an attenuation ratio of seismic acceleration reaction, and n is equal to 4; acquiring mass, length, height of centre of gravity, elastic modulus and moment of inertia of electrical equipment, as well as a seismic influence coefficient corresponding to seismic fortification intensity and a site feature cycle corresponding to a design earthquake grouping and site classification in an electrical equipment installation site; determining limitation conditions of absorber parameters; selecting adaptive absorbers for the electrical equipment; and mounting four adaptive absorbers at the root of the electrical equipment in a square and symmetric manner, wherein edge length of the square of the four adaptive absorbers is equal to that of the square formed by the four absorbers arranged in a square and symmetric manner. According to the invention, a prospective shock-absorbing effect is realized with lower cost, and the seismic performance of the electrical equipment is improved.

Description

technical field [0001] The invention relates to shock absorbing technology, in particular to a four-point electric equipment shock absorbing method and a shock absorbing system. Background technique [0002] Strong earthquakes are one of the major disaster sources. Under the action of a strong earthquake, if the electrical equipment, which is an important equipment of the lifeline project, fails or is severely damaged, it may cause serious disasters and incalculable economic losses. For example: power interruption not only seriously affects normal production and life and earthquake relief work , and may cause secondary disasters such as fires, which seriously threaten people's lives and property safety. [0003] In view of the above reasons, domestic and foreign research institutions and electrical equipment manufacturers have conducted in-depth research on the structure of electrical equipment to improve the seismic performance of electrical equipment itself. In addition,...

AI Technical Summary

Problems solved by technology

[0004] However, there are many types and forms of electrical equipment, and the existing technology lacks effective technical means for selecting a shock absorber for a certain electrical equipment, which leads to blindness in the selection of shock absorbers

In the prior art, if the performance of the shock absorber selected for a certain electrical equipment does not match the dynamic characteristics of the electrical equipment itself and the ground motion parameters, the expected shock absorption effect cannot be achieved, and the safety of the electrical equipment under the action of an earthquake cannot be maintained. , which is not conducive to the safe and stable operation of the power grid
