Embodiment Construction

[0032] The embodiments will be described in detail hereinafter, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following examples do not represent all implementations consistent with this application. These are merely examples of systems and methods consistent with aspects of the present application as recited in the claims.

[0033] The lightning arresters, transformers, post insulators and other equipment in the substation have a slender structure, and the multi-section equipment components are connected together by flanges to form a columnar structure, so they are collectively referred to as support equipment. Most of these devices are composed of brittle ceramic materials, which have poor energy consumption and deformation ability. Under earthquak...

Abstract

The invention provides a combined type damping device, a shock insulation support and a power supply system. The combined type damping device comprises a hanging ring, an inhaul cable, an annular spring damper, a fixing platform and a support body. During use, the hanging ring is fixed to the upper portion of electrical equipment, one end of the inhaul cable is connected with the hanging ring, the other end of the inhaul cable is connected with the annular spring damper, the fixed platform is arranged on the support body, and the annular spring damper is fixed to the fixed platform. When an earthquake comes, the inhaul cable and the annular spring damper jointly act to reduce the earthquake response of the electrical equipment, the inhaul cable can transmit the top displacement of the electrical equipment to the annular spring damper, the annular spring is continuously compressed through piston movement of the long-handle end plate, kinetic energy of the earthquake is converted into potential energy of the spring, and heat energy is generated through friction; and finally, the displacement of the top of the electrical equipment is reduced, and a good damping effect is provided for the electrical equipment.

Description

technical field [0001] The application relates to an earthquake protection device, in particular to a composite damping device, a shock-isolation bracket and a power supply system. Background technique [0002] The lightning arresters, transformers, post insulators and other equipment in the substation have a slender structure, and the multi-section equipment components are connected together by flanges to form a columnar structure, so they are collectively referred to as support equipment. This type of equipment is mostly composed of brittle ceramic materials, which have poor energy consumption and deformation capacity. When an earthquake occurs, due to the columnar structure of the pillar equipment, resonance is easy to occur. The natural frequency of this type of equipment is distributed between 1 and 10Hz. Especially for UHV equipment, its natural frequency is distributed around 2Hz, which is close to the excellent frequency of seismic waves, and it is easy to be damaged...
