An anti-seismic support frame for an electrical system

Abstract

The invention relates to the technical field of electric engineering equipment, in particular to an anti-seismic supporting frame for an electrical system. The anti-seismic supporting frame comprises an upper support, a lower support, a clamp, a buffering locking device and an elastic buffering cushion block. The buffering locking device is arranged on the inner wall of the clamp in a sleeving manner. A hollow cavity with an opening is formed in the buffering locking device, and symmetric beryllium copper elastic pieces are arranged at the upper end and the lower end of the hollow cavity. The elastic buffering cushion block comprises a bearing block, and supporting blocks integrally formed with the bearing block are symmetrically distributed at the left end and the right end of the bearing block. The bottom end of the upper support is located in the beryllium copper elastic pieces at the upper end of the hollow cavity and is connected with protrusions of the beryllium copper elastic pieces at the upper end of the hollow cavity in a clamping manner. The top end of the lower support is located in the beryllium copper elastic pieces at the lower end of the hollow cavity and connected with protrusions of the beryllium copper elastic pieces at the lower end of the hollow cavity in a clamping manner. The supporting blocks are embedded in the hollow cavity. The anti-seismic supporting frame has the beneficial effects that the structure is simple, maintenance is convenient, the effect of isolating earthquakes and buffering earthquakes is achieved, and meanwhile the anti-seismic supporting frame has the good bending resisting capability.

Description

technical field [0001] The invention relates to the technical field of electric power engineering equipment, in particular to an anti-seismic support frame of an electrical system. Background technique [0002] The power facilities in substations in earthquake areas not only need good process layout, but also need to have good shock resistance and shock absorption performance. At present, there are few applications of shock absorption systems for electrical equipment in power facilities in my country, and the existing shock absorption devices cannot meet the requirements. The requirements for electrical equipment during actual construction cannot ensure that the entire power system can operate more safely. [0003] Such as (China) application number 201010524100.6, a shock absorbing device for electrical equipment, can improve the seismic performance of electrical equipment, and can also improve the safety margin of electrical facilities, whether it is better under normal con...

Problems solved by technology

The vibration isolation support is transmitted through the bonding or friction between the steel plate teeth and the rubber unit, so that although the stiffness and damping of the support can be adjusted and controlled according to the actual situation, the effect of vibration isolation and shock absorption is achieved, but the steel plate teeth and the rubber unit Once the bonding or frictional damping between the plate teeth and the rubber unit become smaller, its ability to withstand a certain bending moment will be weakened, and the greater the damping, it will be difficult for relative sliding to occur between the plate teeth and the rubber unit, and a good shock absorption effect cannot be achieved.
