Abstract

The invention relates to a basic shock isolating system for interconnecting electric equipment. An electric equipment bracket is arranged below the electric equipment; the system comprises a bearing table, a shock isolating device and a base box arranged below the bracket in sequence; and a limiting piece for limiting the position of the bearing table is arranged on the side wall of the base box. The shock isolating device is mounted at the bottom of the base box for reducing the transfer of earthquake energy to the upper electric equipment. The bottom of the shock isolating device is fixed with the base box, and the upper part is connected with the bearing table; meanwhile, limiting spring devices are mounted around the base box for preventing the shock isolating device from generating excessive horizontal displacement under the earthquake effect to cause the damage of the shock isolating device; and the limiting springs can achieve the purposes of cushioning the earthquake effect and consuming the earthquake energy. The shock isolating system has such advantages as convenience for construction and clear shock isolating mechanism, and can effectively protect the safety and the stability of the electric equipment under the earthquake effect.

Description

Technical field: [0001] The present invention relates to a base isolation system, and more particularly to a base isolation system for interconnecting 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. Investigations on earthquake damage in recent years have shown that due to the mutual coupling of interconnected electrical equipment under earthquake action, the seismic damage of interconnected equipment is much greater than that of single electrical equipment. In addition, most electrical equipment is composed of brittle ceramic materials, and the The support for fixing electrical equipment has a certain amplification effect on the earthquake, so the electrical equipment, especially the interconnected electrical equipment, has a high vulnerability under the earthquake. [0003] Therefore, it is necessary to propose a technical solution for the ...
